    Fragmented and variable perioperative care exposes patients to unnecessary risks and handoff errors. The perioperative surgical home aims to optimize quality, value-based care. We performed a retrospective evaluation of how a preoperative assessment center could coordinate care through e-mails sent to a patient's healthcare team that initiate discussion on critical clinical information. During 100 clinic days on which 8122 patients were evaluated, 606 triggered e-mails, with a potential impact on 19 elements across the perioperative care spectrum. Four cases were canceled, and 42 cases were rescheduled. By fostering information exchange, these communications could advance patient-centered, value-enhanced quality and safety outcomes.

    The aims of this integrative literature review are to define the role of a preoperative nurse and to describe the main components and hypothetical outcomes of a preoperative nursing care structure before a surgical patient arrives to an elective procedure. The development of medical care has impacted surgical processes, and patients are now spending less time in hospital settings. Patients often enter the hospital on the day of a procedure and are discharged as soon as it is medically safe, creating challenges for nursing care. Preoperative clinics have been opened, and the importance of preoperative nursing care has been widely understood. Previous literature has provided descriptions about the roles, tasks and outcomes of preoperative nurses; however, the terminology is heterogeneous, and the optimal model remains unknown. A systematic procedure for searching, selecting, and evaluating the literature was followed. The data were collected from PubMed and CINAHL between 1 January 2004 and 20 September 2014. In total, 41 articles were included in the study and were analysed by qualitative inductive content analysis. The data provided seven main tasks of a preoperative nurse, tools to support preoperative nursing and outcomes of structured preoperative nursing care. A preoperative nurse is a specialised coordinator of patient care, and the main purposes of this role are to meet the patient's and the family's needs individually and to prepare them for the scheduled procedure and postoperative recovery. By following the structure of the seven main tasks and using different supportive tools, preoperative nursing can positively impact patient and provider satisfaction, patient safety, quality of care and cost savings. A preoperative nursing care structure should be implemented in clinical practice and then evaluated to measure whether the hypothetical outcomes reported in this literature review can be achieved. © 2016 John Wiley & Sons Ltd.

    This article reviews holistic caring-healing therapies that may decrease preoperative anxiety for the surgical patient, based on the philosophy and science of caring developed by Jean Watson, RN, PhD, FAAN. Dr Watson reveals a new paradigm emerging in health care that blends the compassion and caring of nursing in harmony with the curative therapies of medicine. Hypnosis, aromatherapy, music, guided imagery, and massage are integrative caring-healing therapies that may minimize preoperative anxiety. Alternative therapies offer a high-touch balance when integrated with high-tech conventional surgical treatments.

    Patients with valvular heart disease or with a prosthetic heart valve replacement are seen with increasing frequency in clinical practice. The medical care and evaluation of patients with valvular heart disease before valve surgery, but also the post-operative treatment is complex and managed by general practitioners, cardiologists and cardiac surgeons. In this mini-review we will first discuss the preoperative assessment of the two most common valvulopathies, aortic stenosis and mitral regurgitation. Then we will discuss the post-operative care, which includes the management of anticoagulation, serial follow up and as well as the diagnostic assessment of complications such as thromboembolism, hemolysis, endocarditis and valve dysfunction.

    Advances in laser technology have allowed the application of lasers to cosmetic facial skin resurfacing. While this application has been extremely advantageous to patients, the development of pre- and postoperative therapeutic regimens was necessary to mitigate potential complications associated with laser resurfacing. Potential complications of laser resurfacing include prolonged postoperative erythema, hyperpigmentation, hypopigmentation, herpetic, bacterial or candidal infection, and other concerns including scarring and abnormal wound healing. In this report we review the state of the art of preoperative and postoperative care for cosmetic laser resurfacing.

    Research that aimed to analyze the care of nurses to patients, in the daily professional practice, provided in the preoperative period for patients undergoing elective surgery. It is a descriptive research with a qualitative approach that involved 15 nurses from Surgical Units and two nurses from the Surgical Centre of a hospital in the southern region of Brazil. Data was collected in semi-structured interviews conducted from April to July 2011. Data was analyzed using the Collective Subject Discourse (CSD) technique. The information obtained generated three CDS focused on the following ideas: administrative care, instruction in the preoperative period and surgical care in the immediate preoperative period. The results showed that caring consists mostly of giving instructions to the patient in the preoperative period. It is concluded that the care was directed to the physical aspects to the detriment of the psychological, in disagreement with the assistance methodology adopted in the hospital, supported by the Theory of Basic Human Needs.

    Aims To explore the issues and challenges of care transitions in the preoperative environment. Background Ineffective transitions play a role in a majority of serious medical errors. There is a paucity of research related to the preoperative arena and the multiple inherent transitions in care that occur there. Design Qualitative descriptive design was used. Methods Semi-structured interviews were conducted in a 975 bed academic medical center. Results 30 providers and 10 preoperative patients participated. Themes that arose were: (1) Need for clarity of purpose of preoperative care (2) Care coordination (3) Inter-professional boundaries of care (4) Inadequate time and resources. Conclusion Effective transitions in the preoperative environment require that providers bridge scope of practice barriers to promote good teamwork. Preoperative care that is a product of well-informed providers and patients can improve the entire perioperative care process and potentially influence post-operative patient outcomes. Relevance to Clinical Practice Nurses are well positioned to bridge the gaps within transitions of care and accordingly affect health outcomes. PMID:27706872

    This is a case study research that aimed to know, with the adoption of the Theory of Human Caring, the meanings of therapeutic interpersonal relationship between nurse and user on the preoperative nursing visit after the experience of the surgical process. The convenience sample was composed of three nurses and three users of an institution that has updated records to perform highly complex cardiovascular surgery, comprising nine combinations of therapeutic interactions. It was used instruments, structured according to the theory of Jean Watson and North American Nursing Diagnosis Association, Nursing Intervention Classification and Nursing Outcomes Classification taxonomies. The legal and ethical aspects of research involving human subjects were assured. The results revealed three clusters to grasp the significance of preoperative visits by users and five clusters to capture the perception of nurses when they experience this clinical experience.

    Evidence suggests that preoperative clinics, like other hospital outpatient clinics and inpatient wards, fail to systematically provide smoking cessation care to patients having planned surgery. The aim of the study was to assess the efficacy, acceptability, and cost of a multifaceted intervention to facilitate the provision of comprehensive smoking cessation care to patients attending a preoperative clinic. Two hundred ten smoking patients attending a preoperative clinic at a major teaching hospital in Australia took part in the study. One hundred twenty-four patients were randomly assigned to an experimental group and 86 patients to a usual cessation care group. A multifaceted intervention was developed that included the use of opinion leaders, consensus processes, computer-delivered cessation care, computer-generated prompts for care provision by clinic staff, staff training, and performance feedback. Ninety-six percent of experimental group patients received behavioral counseling and tailored self-help material. Experimental group patients were significantly more likely than usual care patients to report receiving brief advice by nursing (79% vs. 47%; P < 0.01) and anaesthetic (60% vs. 39%; P < 0.01) staff. Experimental group patients who were nicotine dependent were also more likely to be offered preoperative nicotine replacement therapy (NRT) (82% vs. 8%; P < 0.01) and be prescribed postoperative NRT (86% vs. 0%; P < 0.01). The multifaceted intervention was found to be acceptable by staff. A multifaceted clinical practice change intervention may be effective in improving the delivery of smoking cessation care to preoperative surgical patients.

    The incidence of obstructive sleep apnea (OSA) has reached epidemic proportions, and it is an often unrecognized cause of perioperative morbidity and mortality. Profound hypoxic injury from apnea during the postoperative period is often misdiagnosed as cardiac arrest due to other causes. Almost a quarter of patients entering a hospital for elective surgery have OSA, and >80% of these cases are undiagnosed at the time of surgery. The perioperative period puts patients at high risk of apneic episodes because of drug effects from sedatives, narcotics, and general anesthesia, as well as from the effects of postoperative rapid eye movement sleep changes and postoperative positioning in the hospital bed. For adults, preoperative screening using the STOP or STOP-Bang questionnaires can help to identify adult patients at increased risk of OSA. In the pediatric setting, a question about snoring should be part of every preoperative examination. For patients with known OSA, continuous positive airway pressure should be continued postoperatively. Continuous pulse oximetry monitoring with an alarm system can help to prevent apneic catastrophes caused by OSA in the postoperative period.

    The records of 70 patients with oral cancer who were treated at a single institution between 2008 and 2014 were reviewed. The body temperature, white blood cell count, and C-reactive protein (CRP) levels were compared between those who had received preoperative oral care (oral care group) and those who had not received any (non-oral care group). When the patients were divided into those who underwent minimally invasive surgery and those who underwent severely invasive surgery, the mean CRP level in the early postoperative period was lower in the oral care group as compared with the non-oral care group in those who underwent minimally invasive surgery as well as those who underwent severely invasive surgery. However, the mean CRP level was most evidently reduced in the severely invasive group on days 1 and 3–5. However, no significant differences were observed with regard to the percentage of postoperative infectious complications (for example, surgical site infection, anastomotic leak and pneumonia) between the oral care (13.6%) and non-oral care (20.8%) groups, though a reduced prevalence of postoperative complications following preoperative oral care was noted. The results of the present study suggest that preoperative oral care can decrease inflammation during the early postoperative stage in patients with oral cancer who undergo severely invasive surgery.

    Uterine morcellation in minimally invasive surgery has recently come under scrutiny because of inadvertent dissemination of malignant tissue, including leiomyosarcomas commonly mistaken for fibroids. Identification of preoperative risk factors is crucial to ensure that oncologic care is delivered when suspicion for malignancy is high, while offering minimally invasive hysterectomies to the remaining patients. The aim of this study was to characterize risk factors for uterine leiomyosarcomas by reviewing preoperative, intraoperative, and postoperative data with an emphasis on the presence of concurrent fibroids. A retrospective case-control study of women undergoing hysterectomy with pathologic diagnosis of uterine leiomyosarcoma at a tertiary care center between January 2005 and April 2014. Thirty-one women were identified with leiomyosarcoma and matched to 124 controls. Cases with leiomyosarcoma were more likely to have undergone menopause and to present with larger uteri (19- vs 9-week sized), with the most common presenting complaint being a pelvic mass (35.5% vs 8.9%). Controls were ten times more likely to have undergone a tubal ligation (30.6% vs 3.2%). Endometrial sampling detected malignancy preoperatively in only 50% of cases. Leiomyosarcomas were more commonly present when pelvic masses were identified in addition to fibroids on preoperative imaging. Most leiomyosarcoma cases (77.4%) were performed by oncologists via an abdominal approach (83.9%), with only 2 of 31 leiomyosarcomas being morcellated. Comparative analysis of preoperative imaging and postoperative pathology showed that in patients with leiomyosarcoma, fibroids were misdiagnosed 58.1% of the time, and leiomyosarcomas arose directly from fibroids in only 6.5% of cases. Leiomyosarcoma risk factors include older age/postmenopausal status, enlarged uteri of greater than 10 weeks, and lack of previous tubal ligation. Preoperative testing failed to definitively identify leiomyosarcomas, although

    Preanesthesia preparation will continue to stimulate creativity and debate. Strategies for process improvement will take various shapes and require tools previously unfamiliar to many medical managers. At UNC Health System, anesthesiologists currently are committed to the centralized preanesthesia clinic approach used in PreCare. To date, their strategies have been validated by their institutional measures of success: a 0.7% first-case AM work-up rate, a 5% no PreCare visit rate, a 5% consent problem rate, and a 0% rejected specimen rate, with a 43% blood-draw rate for all patients. As their health system expands, however, other strategies and preparation modalities may become necessary. Telemedicine and Internet-dependent processes are appealing in the highly educated and technologically sophisticated marketplace. As the region becomes increasingly urbanized, local employment patterns prevent easy access to services, and functional compromises, such as bypassing PreCare or reliance on telephone or on-line interviews for preparation, may become necessary. The need to expand PreCare in the near future is already evident. As was found during initial planning, process improvement and space planning are enhanced by computer modeling. UNC Health System employed a proprietary animated simulation modeling (ASM) tool, MedModel, (ProModel, Orem, UT), although other techniques exist for the same purpose. Use of ASM as a strategy management tool allowed generation of ideal space-time-personnel scenarios that could expose potential problems before resources and physical restructuring occurred. ASM also can be used to compare data obtained from real-time observations to any reference scenario, including any that looks at economic measures of process, to help refine strategic visions before instituting tactical solutions. Used in this manner, ASM can reveal physical, temporal, personnel, and policy-related factors not otherwise seen as exerting effects on overall preprocedural

    2017-01-01

    Background Bilateral breast magnetic resonance imaging (MRI) is commonly used in the diagnostic workup of breast cancer (BC) to assess extent of disease and identify occult foci of disease. However, evidence for routine use of pre-operative MRI is lacking. Breast MRI is costly and can lead to unnecessary tests and treatment delays. Clinical care pathways (care paths) are value-based guidelines, which define management recommendations derived by expert consensus and available evidence based data. At Cleveland Clinic, care paths created for newly diagnosed BC patients recommend selective use of pre-operative MRI. We evaluated the number of pre-operative MRIs ordered before and after implementing an institution wide BC care paths in April 2014. Methods A retrospective review was conducted of BC cases during the years 2012, 2014, and part of 2015. Patient, tumor and treatment characteristics were collected. Pre-operative MRI utilization was compared before and after care path implementation. Results We identified 1,515 BC patients during the study period. Patients were more likely to undergo pre-operative MRI in 2012 than 2014 (OR: 2.77; P<0.001; 95% CI: 1.94–3.94) or 2015 (OR: 4.14; P<0.001; 95% CI: 2.51–6.83). There was a significant decrease in pre-operative MRI utilization between 2012 and 2014 (P<0.001) after adjustment for pre-operative MRIs ordered for care path indications. Conclusions Implementation of online BC care paths at our institution was associated with a decreased use of pre-operative MRI overall and in patients without a BC care path indication, driving value based care through the reduction of pre-operative breast MRIs.

    Pre-operative assessment is required prior to the majority of elective surgical procedures, primarily to ensure that the patient is fit to undergo surgery, whilst identifying issues that may need to be dealt with by the surgical or anaesthetic teams. The post-operative management of elective surgical patients begins during the peri-operative period and involves several health professionals. Appropriate monitoring and repeated clinical assessments are required in order for the signs of surgical complications to be recognised swiftly and adequately. This article examines the literature regarding pre-operative assessment in elective orthopaedic surgery and shoulder surgery, whilst also reviewing the essentials of peri- and post-operative care. The need to recognise common post-operative complications early and promptly is also evaluated, along with discussing thromboprophylaxis and post-operative analgesia following shoulder surgery.

    To estimate the preoperative levels of anxiety and depression in patients awaiting heart surgery and to identify the risk factors associated with the development of these mood disorders. To evaluate the relationship between preoperative anxiety and depression and postoperative morbidity. Prospective longitudinal study in a sample of 100 patients undergoing heart surgery. We carried out a preoperative structured interview in which the patient completed the Hospital Anxiety and Depression Scale, and sociodemographic (age, sex, marital status, and income) and surgical variables (surgical risk, type of surgery, length of preoperative hospital stay, and surgical history) were also recorded. Pain, analgesic use, and postoperative morbidity were evaluated in the intensive care unit. Thirty-two percent of the patients developed preoperative anxiety and 19%, depression. Age < 65 years (odds ratio=3.05; 95% confidence interval, 1.27-7.3) was the only significant risk factor for developing preoperative anxiety. A length of preoperative hospital stay ≥ 3 days was the main risk factor for preoperative depression (odds ratio=4.59; 95% confidence interval, 1.6-13.17). Preoperative anxiety significantly increased the postoperative pain and analgesic consumption. Neither anxiety nor depression significantly modified the rest of the postoperative variables associated with morbidity in the intesive care unit. Anxiety and depression are mood disorders that are detected in patients awaiting heart surgery, with age <65 years and a prolonged preoperative hospital stay being decisive factors in the development of these conditions. Although preoperative anxiety increased the postoperative pain in these patients, their state of mind did not modify their postoperative course. Copyright © 2011 Sociedad Española de Cardiología.

    Health-care costs following acute hospital care have been identified as a major contributor to regional variation in Medicare spending. This study investigated the associations of preoperative physical therapy and post-acute care resource use and its effect on the total cost of care during primary hip or knee arthroplasty. Historical claims data were analyzed using the Centers for Medicare & Medicaid Services Limited Data Set files for Diagnosis Related Group 470. Analysis included descriptive statistics of patient demographic characteristics, comorbidities, procedures, and post-acute care utilization patterns, which included skilled nursing facility, home health agency, or inpatient rehabilitation facility, during the ninety-day period after a surgical hospitalization. To evaluate the associations, we used bivariate and multivariate techniques focused on post-acute care use and total episode-of-care costs. The Limited Data Set provided 4733 index hip or knee replacement cases for analysis within the thirty-nine-county Medicare hospital referral cluster. Post-acute care utilization was a significant variable in the total cost of care for the ninety-day episode. Overall, 77.0% of patients used post-acute care services after surgery. Post-acute care utilization decreased if preoperative physical therapy was used, with only 54.2% of the preoperative physical therapy cohort using post-acute care services. However, 79.7% of the non-preoperative physical therapy cohort used post-acute care services. After adjusting for demographic characteristics and comorbidities, the use of preoperative physical therapy was associated with a significant 29% reduction in post-acute care use, including an $871 reduction of episode payment driven largely by a reduction in payments for skilled nursing facility ($1093), home health agency ($527), and inpatient rehabilitation ($172). The use of preoperative physical therapy was associated with a 29% decrease in the use of any post-acute care

    The aim of this study was to evaluate parental satisfaction with preoperative assessment and education in a pediatric presurgical care center (PSCC) as well as parental use of a computer instructional video, EMMI, which is a product of Emmi Solutions (Chicago, IL), a health information company for patients. A prospective, exploratory, comparative, and correlational descriptive design was implemented. A 23-item questionnaire was completed by 542 parents or legal guardians at the end of their child's PSCC visit. Very high overall satisfaction was seen with the visit. Highest overall satisfaction was seen related to nurse practitioner and registered nurse behaviors and lowest satisfaction to operational aspects. This study validates parents' perceptions of the high value of nurses' explanations, respect shown, and response to questions during preoperative assessment of the child and education of the family anticipating surgery. Identification of less satisfying aspects of the presurgical experience provides opportunities for improvement. Copyright © 2015 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc.

We retrospectively analysed the independent association of pre-operative variables with postoperative critical care admission using multivariable logistic regression for patients undergoing elective surgery from January to December 2011. Of 5432 patients, 338 (6.2%) were admitted postoperatively to the critical care unit. In multivariate analysis, the odds ratios (95% CI) for critical care admission were: 2.2 (1.1-4.6), p = 0.037; 3.2 (1.2-8.1), p = 0.017; and 5.1 (1.8-14.9), p = 0.002, for STOP-BANG scores of 4, 5 and ≥ 6, respectively.

    Abstract Objective: estimate the prevalence of anxiety in laryngectomy patients in the pre and postoperative periods and its relation with the self-care level. Method: observational research of 40 patients with stage IV laryngeal cancer. Three observations took place: in the preoperative phase, at seven and at 14 days after the surgery; between June 2010 and December 2012. Two self-care levels were defined: self-sufficient and needing help for activities of daily living and treatment-related activities. To assess the anxiety levels, Zigmond's hospital anxiety scale (1983) was used. Results: in the preoperative and postoperative phases, the patients presented high levels of anxiety. Concerning self-care, on average, self-sufficient patients presented lower levels of anxiety than patients who needed help to accomplish activities of daily living and activities deriving from the surgery, without significant differences. Conclusion: anxiety is present at all times in laryngectomy patients and the reduction of the self-care deficit seems to decrease it, without putting a permanent end to it. PMID:27305181

    Reducing postoperative morbidity and mortality is important not only for patients' outcome but for reduction of financial burden on society. Precise and accurate preoperative evaluation of surgical risk factors is crucial to plan appropriate postoperative allocation of medical resources. American Society of Anesthesiologists physical status is a traditional measure to describe preoperative risk of patients undergoing surgery. In the last decade, several scoring systems with better sensitivity and specificity were reported and validated. Charlson Age-comorbidity Index, Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) are frequently used scoring systems. Several lines of evidence indicate that negligence of medical caregivers cause substantial numbers of errors to patients and often leads to severe complications or deaths. Full compliances to surgical checklists and implementation of medical team will help reduce these errors and lead to better patients' postoperative outcomes.

    Objective: To determine whether the use of a set of preoperative variables can predict the need for postoperative ICU admission. Methods: This was a prospective observational cohort study of 120 patients undergoing elective pulmonary resection between July of 2009 and April of 2012. Prediction of ICU admission was based on the presence of one or more of the following preoperative characteristics: predicted pneumonectomy; severe/very severe COPD; severe restrictive lung disease; FEV1 or DLCO predicted to be < 40% postoperatively; SpO2 on room air at rest < 90%; need for cardiac monitoring as a precautionary measure; or American Society of Anesthesiologists physical status ≥ 3. The gold standard for mandatory admission to the ICU was based on the presence of one or more of the following postoperative characteristics: maintenance of mechanical ventilation or reintubation; acute respiratory failure or need for noninvasive ventilation; hemodynamic instability or shock; intraoperative or immediate postoperative complications (clinical or surgical); or a recommendation by the anesthesiologist or surgeon to continue treatment in the ICU. Results: Among the 120 patients evaluated, 24 (20.0%) were predicted to require ICU admission, and ICU admission was considered mandatory in 16 (66.6%) of those 24. In contrast, among the 96 patients for whom ICU admission was not predicted, it was required in 14 (14.5%). The use of the criteria for predicting ICU admission showed good accuracy (81.6%), sensitivity of 53.3%, specificity of 91%, positive predictive value of 66.6%, and negative predictive value of 85.4%. Conclusions: The use of preoperative criteria for predicting the need for ICU admission after elective pulmonary resection is feasible and can reduce the number of patients staying in the ICU only for monitoring.

    Surgery for elderly women is likely to increase steadily as the population of elderly people increases globally. Although increasing age increases perioperative morbidity and mortality, the functional age and physiologic reserve rather than chronological age is more important in preventing complications. Preparation for surgery, with special attention to functional capacity and activity, mental status, and existing comorbid conditions, can improve outcomes. Perioperative management must be tailored to physiologic changes of ageing, which affect respiratory, cardiac and renal function, as well as guidelines for preventing infection and thrombotic events. Of particular note is the enhanced effect of narcotic medications in elderly people, which affects intraoperative and postoperative management of pain. Prevention of postoperative delirium is accomplished through preoperative and postoperative planning. Discharge planning, particularly for frail elderly people, must start before surgery.

    Long-term multidisciplinary care after bariatric surgery is important for weight maintenance and management of co-morbidities. Despite this, the rate of attendance to follow-up appointments is universally low. To identify patient factors that contribute to adherence to follow-up care after bariatric surgery. Three university-affiliated hospitals in Canada A cohort study of 388 patients who underwent bariatric surgery from January 2011 to December 2011 was performed. This program mandates multidisciplinary follow-up care at 3, 6, and 12 months, and annually thereafter. Patients' socioeconomic, psychosocial, and medical and psychiatric co-morbidities were recorded prospectively. Adherence to follow-up care was defined as having attended the majority of clinic visits (3 or 4 out of 4); all other patients were considered nonadherent. The mean age of patients was 45.0 years, 81.2% were female, and the majority underwent a gastric bypass (91.8%) versus a sleeve gastrectomy (8.2%); 62.1% of patients were adherent to follow-up appointments. Patients older than 25 years had a higher adherence rate than those who were younger (63.2% versus 37.5%, P = .040). Patients with full-time or part-time employment had a significantly higher adherence rate than those who were unemployed or retired (65.6% versus 50.0%, P = .017, odds ratio 1.9). Patients with obstructive sleep apnea (OSA) before surgery had higher follow-up adherence than those without OSA (62.2% versus 37.8%, P = .044). In multivariate analysis, employment remained an independent predictor of follow-up adherence (P = .017). Employment was the strongest predictor of attendance to follow-up clinic. Patients with OSA and older patients were also more likely to return consistently for scheduled follow-up. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc.

    Hygiene is becoming more and more important in long-term care facilities. Long-term care facilities are subject to monitoring by the Public Health Service (PHS) and other authorities. For the PHS in Bavaria the Bavarian Health and Food Safety Authority (Landesamt für Gesundheit und Lebensmittelsicherheit, LGL) published a hygiene monitoring concept and there exists an inspection guide developed by a specialist department for nursing homes and institutions for the handicapped (Fachstelle für Pflege und Behinderteneinrichtungen, FQA). Because inspections are performed in multiprofessional teams, it makes sense to use a coordinated inspection catalog. The aim was to integrate hygienic requirements specified in the Bavarian guidelines for hygiene by the LGL into the inspection guide published by the FQA to obtain a quality assured surveillance. The involved parties were questioned about the inspection guide and their hygiene management and then the hygiene criteria of the LGL were implemented into the inspection guide. Questions dealing with hygiene requirements concerning intensive care, management of multidrug resistant bacteria and interviews with the person responsible for infection control in the facility itself were developed for the first time and were integrated into the inspection guide. The revised inspection guide was tested for its applicability. With the revised inspection guide there now exists a tool which allows not only comprehensive inspections of the facilities including hygiene issues but also a good cooperation of the various parties involved. There are many actions which have to be conveyed into the future, especially programs to train staff to apply the inspection guide and to enhance the ability of all participants to act in cooperation. The guide will also allow the facilities to cooperate more easily and more closely, as the guide takes the respective problems and challenges of the different facilities into consideration.

Three observations took place: in the preoperative phase, at seven and at 14 days after the surgery; between June 2010 and December 2012. Two self-care levels were defined: self-sufficient and needing help for activities of daily living and treatment-related activities. To assess the anxiety levels, Zigmond's hospital anxiety scale (1983) was used. in the preoperative and postoperative phases, the patients presented high levels of anxiety. Concerning self-care, on average, self-sufficient patients presented lower levels of anxiety than patients who needed help to accomplish activities of daily living and activities deriving from the surgery, without significant differences. anxiety is present at all times in laryngectomy patients and the reduction of the self-care deficit seems to decrease it, without putting a permanent end to it. estimar a prevalência de ansiedade do paciente laringectomizado no pré-operatório e pós-operatório e sua relação com o nível de autocuidado. pesquisa observacional de 40 pacientes com câncer da laringe estágio IV.

    Screen-based computer simulations are considered a method of skill teaching in health education. This study examined the effect of screen-based computer simulation on knowledge, skill, and the clinical decision-making process in teaching preoperative and postoperative care management to second-year students in an undergraduate school of nursing. It is a randomized controlled study. The study sample was composed of 82 students. They received education in screen-based computer simulation (n = 41) and skill laboratories (n = 41). Three instruments were used: a preoperative and postoperative care management cognitive level assessment test, skill control lists of preoperative and postoperative care management, and the Clinical Decision Making in Nursing Scale. There was not a significant difference between the students' posteducation knowledge levels (P = .421), practical deep breathing and coughing exercise education skills (P = .867), or clinical decision-making scale total and subscale scores (P = .065). However, a significant difference was found between the admission of the patient in the surgical clinic after surgery skill scores of the students (P = .04). Education provided in the screen-based computer simulation laboratory was equivalent to that provided in the skill laboratory.

    Background American College of Cardiology/American Heart Association guidelines describe the perioperative evaluation as “a unique opportunity to identify patients with hypertension,” however factors such as anticipatory stress or medication noncompliance may induce a bias toward higher blood pressure, leaving clinicians unsure about how to interpret preoperative hypertension. Information describing the relationship between preoperative intake blood pressure and primary care measurements could help anesthesiologists make primary care referrals for improved blood pressure control in an evidence-based fashion. We hypothesized that the preoperative examination provides a useful basis for initiating primary care blood pressure referral. Methods We analyzed retrospective data on 2807 patients who arrived from home for surgery and who were subsequently evaluated within 6 months after surgery in the primary care center of the same institution. After descriptive analysis, we conducted multiple linear regression analysis to identify day-of-surgery (DOS) factors associated with subsequent primary care blood pressure. We calculated the sensitivity, specificity, and positive and negative predictive value of different blood pressure referral thresholds using both a single-measurement and a two-stage screen incorporating recent preoperative and DOS measurements for identifying patients with subsequently elevated primary care blood pressure. Results DOS systolic blood pressure (SBP) was higher than subsequent primary care SBP by a mean bias of 5.5mmHg (95% limits of agreement +43.8 to −32.8). DOS diastolic blood pressure (DBP) was higher than subsequent primary care DBP by a mean bias of 1.5mmHg (95% limits of agreement +13.0 to −10.0). Linear regression of DOS factors explained 19% of the variability in primary care SBP and 29% of the variability in DBP. Accounting for the observed bias, a two-stage SBP referral screen requiring preoperative clinic SBP≥140mmHg and DOS

    To compare the clinical competencies of second-year anaesthesiology residents and physician assistants (PA) in the preoperative anaesthesiology outpatient clinic. Comparative qualitative observational study. The two study groups were compared using 5 test stations representing 5 different cases of varying degrees of complexity with standardized patients. For each case, the patients and two anaesthesiologists assessed the results of the PAs and the residents using a quantitative scoring system for 4 clinical skills relevant to the preoperative anaesthesiology outpatient clinic. These skills were history-taking, physical examination, communication, and reporting. At each station, a score was calculated for each skill. The groups' scores were subsequently compared. 9 PAs and 11 residents carried out the station tests. There were no significant differences between the two groups of participants. In this study in a preoperative anaesthesiology outpatient clinic no difference in clinical competencies was found between PAs and second-year anaesthesiology residents.

    Introduction Patients and their families are understandably anxious about the risk of complications and unfamiliar experiences following cardiac surgery. Providing information about postoperative care in the intensive care unit (ICU) to patients and families may lead to lower anxiety levels, and increased satisfaction with healthcare. The objectives of this study are to evaluate the effectiveness of preoperative patient education provided for patients undergoing elective cardiac surgery. Methods and analysis 100 patients undergoing elective coronary artery bypass graft, with or without valve replacement surgery, will be recruited into a 2-group, parallel, superiority, double-blinded randomised controlled trial. Participants will be randomised to either preoperative patient education comprising of a video and ICU tour with standard care (intervention) or standard education (control). The primary outcome measures are the satisfaction levels of patients and family members with ICU care and decision-making in the ICU. The secondary outcome measures are patient anxiety and depression levels before and after surgery. Ethics and dissemination Ethical approval has been obtained from the Joint Chinese University of Hong Kong—New Territories East Cluster Clinical Research Ethics Committee (reference number CREC 2015.308). The findings will be presented at conferences and published in peer-reviewed journals. Study participants will receive a 1-page plain language summary of results.

    Obtaining appropriate preoperative risk-specific staging investigations for localized renal cell carcinoma (rcc) is a recognized quality indicator. The goal of the present work was to determine the use and appropriateness of preoperative investigations in patients undergoing curative surgery for rcc. This population-based retrospective study of patients having surgery for localized rcc recorded the use of preoperative imaging and laboratory investigations within 6 months of surgery. "Appropriate" stage-specific investigations were determined using recognized published guidelines. The study cohort consisted of 544 patients with 72.8% being stage i, 18.4% being stage ii, and 8.8% being stage iii by clinical TNM (2002) criteria. In 61.6%, chest imaging was obtained by chest radiography or computed tomography (ct) within 3 months preoperatively; in 75.6%, such imaging was obtained within 6 months. Abdominal ct imaging was obtained in 97.1% of patients before surgery, with 77.5% of patients receiving such imaging within 3 months of surgery. Complete blood count, electrolytes, and creatinine were measured in 99.1% of patients, but those tests plus other recommended blood tests including calcium, alkaline phosphatase, and liver function were measured in only 17.7%. In this study, most patients received appropriate abdominal imaging, but chest imaging was underutilized in the overall cohort. Despite being recommended, blood tests such as liver function, alkaline phosphatase, and calcium were completed in fewer than 2 of 10 patients. This analysis provides the groundwork for quality improvement initiatives directed to the use of preoperative investigations in localized rcc.

    Patent ductus arteriosus (PDA) is common in premature infants. In very low birth weight infants (VLBWI), PDA requires surgical therapy in many cases. It is unclear to know at-risk infants showing cardio-dysfunction after PDA surgery. The purpose of this study was to identify at-risk infants showing cardio-dysfunction after surgery for patent ductus arteriosus (PDA). We examined the relationship between left ventricular (LV) performance before and after PDA ligation in a retrospective observational cohort study. We studied 64 preterm neonates with symptomatic PDA before and after surgical ligation. Echocardiographic examinations were performed pre- and postoperatively. M-mode measurements included left ventricular internal dimension in end-diastole (LVIDd) and LV fractional shortening (FS). All cases showed decreased LVFS after PDA closure. Most cases (49/64, 77%) showed postoperative FS decreased to below normal (<28%). Preoperative relative LVIDd was significantly larger in abnormal FS infants (137 ± 18%) than in normal FS infants (118 ± 11%; p<0.01). A cut-off value of preoperative relative LVIDd (absolute LVIDd/normal value) for predicting postoperative cardio-dysfunction was 127.4% (sensitivity, 0.735; specificity, 0.933; area under curve, 0.817). Determination of preoperative LVIDd might facilitate earlier identification of infants needing early PDA surgery and postoperative intensive care. © 2013 Elsevier Ireland Ltd. All rights reserved.

    Evaluate the factors associated with postoperative ICU admission in patients undergoing surgical management of degenerative lumbar spine disease. Patients undergoing surgery for degenerative lumbar spine disease were enrolled into a prospective registry over a 2-year period. Preoperative variables (age, gender, ASA grade, ODI%, CAD, HTN, MI, CHF, DM, BMI, depression, anxiety) and surgical variables (instrumentation, arthrodesis, estimated blood loss, length of surgery) were collected prospectively. Postoperative ICU admission details were retrospectively determined from the electronic medical record. Student's t test (continuous variables) and Chi-square test (categorical variables) were used to determine the association of each preoperative and surgical variable with ICU admission. 808 Patients (273 laminectomy, 535 laminectomy and fusion) were evaluated. Forty-one (5.1%) patients were found to have postoperative ICU admissions. Reasons for admission included blood loss (12.2%), cardiac (29.3%), respiratory (19.5%), neurologic (31.7%), and other (7.3%). For preoperative variables, female gender (P < 0.001), history of CAD (P = 0.003), history of MI (P = 0.008), history of CHF (P = 0.001), age (P = 0.025), and ASA grade (P = 0.008) were significantly associated with ICU admission. For surgical variables, estimated blood loss (P < 0.001) and length of surgery (P < 0.001) were significantly associated with ICU admission. Age, female gender, ASA grade, cardiac comorbidities, intraoperative blood loss, and length of surgery were associated with increased risk of postoperative ICU admission. Knowledge of these factors can aid surgeons in patient selection and preoperative discussion with patients about potential need for unexpected admission to the ICU.

    Platelet dysfunction is an important cause of bleeding early after cardiac surgery. Whole-blood multiple electrode aggregometry (MEA), investigating the adhesion and aggregation of activated platelets onto metal electrodes, has shown correlations with platelet concentrates transfusion in this setting. Platelet activity in vivo is dependent on shear stress, an aspect that cannot be investigated with MEA, but with the cone and plate(let) analyzer (CPA) Impact-R that measures the interaction of platelets and von Willebrand factor (vWF) in whole blood under shear. We hypothesized that preoperative CPA may show better correlation with platelet concentrates transfusion post-cardiac surgery than MEA, since it is dependent on both platelet activity and platelet interaction with vWF multimers. Blood was obtained preoperatively from 30 patients undergoing aorto-coronary bypass (ACB) and 20 patients with aortic valve (AV) surgery. MEA was performed in hirudin-anticoagulated blood. The Impact-R analyses were performed in blood anticoagulated with hirudin, heparin or the standard anticoagulant citrate. For the light microscopy images obtained, the parameter surface coverage (SC) was calculated. Preoperative Impact-R results were abnormally decreased in AV patients and significantly lower than in ACB patients. For the Impact-R analysis performed in citrated blood, no correlation with platelet concentrates transfusion was observed. In contrast, MEA was comparable between the groups and correlated significantly with intraoperative platelet concentrates transfusion in both groups (rho between -0.47 and -0.62, p < 0.05). Multiple electrode aggregometry appeared more useful and easier to apply than CPA for preoperatively identifying patients with platelet concentrates transfusion in cardiac surgery.

    As the need for joint replacements will continue to rise, the outcome of primary total hip replacement (THR) must be improved and stabilised at a high level. In this study, we investigated whether pre-operative risk factors, such as gender, age and body weight at the time of the surgery or a restricted physical status (ASA-Status > 2 or Kellgren and Lawrence grade > 2) have a negative influence on the post-operative results or on patient satisfaction. Retrospective data collection and a prospective interview were performed with 486 patients who underwent primary total hip replacement between January 2007 and December 2010 in our hospital. The patients' satisfaction and quality of life were surveyed with the WOMAC-Score, SF-36 and EuroQol-5. Differences between more than two independent spot tests were tested with the non-parametric Kruskal-Wallis test. Differences between two independent spot tests were tested with the non-parametric Mann-Whitney U test. The frequencies were reported and odds ratios calculated. The confidence interval was set at 95 %. The level of significance was p < 0.05. The average WOMAC-Score was 77.1 and the total score of the SF-36 was 66.9 points. The patients declared an average EuroQol Index of 0.81. Our data show that the patients' gender did not influence the duration of surgery or the scores. However, female patients tended to exhibit more postoperative complications. However, increased patient age at the time of surgery was associated with an increased OR for duration of surgery, length of stay and risk of complications. Patients who had a normal body weight at time of the surgery showed better peri- and post-operative results. We showed that the preoperative estimated Kellgren and Lawrence grade had a significant influence on the duration of surgery. The ASA classification influenced the duration of surgery as well the length of stay and the rate of complications. The quality of results after primary THR depends on

    Older patients are at greater risk for postoperative complications, yet they are less likely than younger patients to ask questions about surgery. To design an intervention to improve preoperative decision making and manage postoperative expectations. A Patient and Family Advisory Council (PFAC) was created to help identify preoperative decisional needs. The PFAC included 4 men and women who had previous experience with high-risk surgery as older patients or their family members; the PFAC met monthly at a local library from May 2014 to April 2015 to examine findings from a prior qualitative study and to integrate themes with PFAC members' experiences. Patient observations included 91 recorded conversations between patients and surgeons and 61 patient interviews before and after surgery. The PFAC members and other stakeholders evaluated 118 publicly available questions and selected 12 corresponding to identified needs to generate a question prompt list (QPL). Three focus groups, including 31 community members from diverse backgrounds, were conducted at community centers in Madison and Milwaukee, Wisconsin, to refine the QPL. A clinical pilot with 42 patients considering surgery was conducted in one outpatient surgical clinic in Madison. Generation of a QPL to address patients' preoperative informational and decisional needs. Through exploration of qualitative data, the PFAC noted 3 critical problems. Patients and family members believed surgery had to be done, were surprised that postoperative recovery was difficult, and lacked knowledge about the perioperative use of advance directives. The PFAC identified a need for more information and decisional support during preoperative conversations that included clarification of treatment options, setting postoperative expectations, and advance care planning. The following 3 question prompt categories arose: "Should I have surgery?" "What should I expect if everything goes well?" and "What happens if things go wrong?" The

    Self-reported information about smoking habit and cigarette consumption can be inaccurate and subject to bias in the clinical setting. Accurate assessment of a given smoking history at point-of-care is valuable. We describe the use of a comprehensive smoking questionnaire and the use of a disposable biomarker test to verify and quantify the exposure to tobacco smoke. This point-of-care test (SmokeScreen) is a 6-min, easy-to-use urine test that measures nicotine and its breakdown products. One hundred consecutive patients attending plastic surgery pre-assessment clinic filled in the questionnaire and gave a consented urine sample. Qualitative and semi-quantitative assessment of tobacco consumption was observed by a simple sample colour change set against a standardised colorimetric chart for nicotine metabolite containing urine. The questionnaire self-reported smoking prevalence was 30% with 98% test specificity. The cotinine validated smoking prevalence was 54% with a 26% self-denial rate. Half the patients (n = 15) who admitted smoking on the questionnaire underreported the amount they smoked daily, as quantified by biochemical measurement. Objective biochemical assessment shows that 26% of self-reporting non-smokers via self-completed questionnaire studies are actual smokers attending this pre-assessment clinic. When patients did report smoking there was consistent underreporting of cigarette consumption.

    Purpose: The German rectal study determined that preoperative radiation therapy (RT) as a component of combined-modality therapy decreased local tumor recurrence, increased sphincter preservation, and decreased treatment toxicity compared with postoperative RT for rectal cancer. We evaluated the use of preoperative RT after the presentation of the landmark German rectal study results and examined the impact of tumor and sociodemographic factors on receiving preoperative RT. Methods and Materials: In total, 20,982 patients who underwent surgical resection for T3-T4 and/or node-positive rectal adenocarcinoma diagnosed from 2000 through 2006 were identified from the Surveillance, Epidemiology, and End Results tumor registries. We analyzed trends in preoperative RT use before and after publication of the findings from the German rectal study. We also performed multivariate logistic regression to identify factors associated with receiving preoperative RT. Results: Among those treated with RT, the proportion of patients treated with preoperative RT increased from 33.3% in 2000 to 63.8% in 2006. After adjustment for age; gender; race/ethnicity; marital status; Surveillance, Epidemiology, and End Results registry; county-level education; T stage; N stage; tumor size; and tumor grade, there was a significant association between later year of diagnosis and an increase in preoperative RT use (adjusted odds ratio, 1.26/y increase; 95% confidence interval, 1.23-1.29). When we compared the years before and after publication of the German rectal study (2000-2003 vs. 2004-2006), patients were more likely to receive preoperative RT than postoperative RT in 2004-2006 (adjusted odds ratio, 2.35; 95% confidence interval, 2.13-2.59). On multivariate analysis, patients who were older, who were female, and who resided in counties with lower educational levels had significantly decreased odds of receiving preoperative RT. Conclusions: After the publication of the landmark German rectal

    Evaluation of the patient's medical history and a physical examination are the cornerstones of risk assessment prior to elective surgery and may help to optimize the patient's preoperative medical condition and to guide perioperative management. Whether the performance of additional technical tests (e.g. blood chemistry, ECG, spirometry, chest-x-ray) can contribute to a reduction of perioperative risk is often not very well known or controversial. Similarly, there is considerable uncertainty among anesthesiologists, internists and surgeons with respect to the perioperative management of the patient's long-term medication. Therefore, the German Scientific Societies of Anesthesiology and Intensive Care Medicine (DGAI), Internal Medicine (DGIM) and Surgery (DGCH) have joined to elaborate and publish recommendations on the preoperative evaluation of adult patients prior to elective, non-cardiac and non-lung resection surgery. In the first part the general principles of preoperative evaluation are described (part A). The current concepts for extended evaluation of patients with known or suspected major cardiovascular disease are presented in part B. Finally, the perioperative management of patients' long-term medication is discussed (part C). The concepts proposed in these interdisciplinary recommendations endorsed by the DGAI, DGIM and DGCH provide a common basis for a structured preoperative risk assessment and management. These recommendations aim to ensure that surgical patients undergo a rational preoperative assessment and at the same time to avoid unnecessary, costly and potentially dangerous testing. The joint recommendations reflect the current state-of-the-art knowledge as well as expert opinions because scientific-based evidence is not always available. These recommendations will be subject to regular re-evaluation and updating when new validated evidence becomes available.

    Evaluation of the patient's medical history and a physical examination are the cornerstones of risk assessment prior to elective surgery and may help to optimize the patient's preoperative medical condition and to guide perioperative management. Whether the performance of additional technical tests (e.g. blood chemistry, ECG, spirometry, chest-x-ray) can contribute to a reduction of perioperative risk is often not very well known or controversial. Similarly, there is considerable uncertainty among anesthesiologists, internists and surgeons with respect to the perioperative management of the patient's long-term medication. Therefore, the German Scientific Societies of Anesthesiology and Intensive Care Medicine (DGAI), Internal Medicine (DGIM) and Surgery (DGCH) have joined to elaborate and publish recommendations on the preoperative evaluation of adult patients prior to elective, non-cardiac and non-lung resection surgery. In the first part the general principles of preoperative evaluation are described (part A). The current concepts for extended evaluation of patients with known or suspected major cardiovascular disease are presented in part B. Finally, the perioperative management of patients' long-term medication is discussed (part C). The concepts proposed in these interdisciplinary recommendations endorsed by the DGAI, DGIM and DGCH provide a common basis for a structured preoperative risk assessment and management. These recommendations aim to ensure that surgical patients undergo a rational preoperative assessment and at the same time to avoid unnecessary, costly and potentially dangerous testing. The joint recommendations reflect the current state-of-the-art knowledge as well as expert opinions because scientific-based evidence is not always available. These recommendations will be subject to regular re-evaluation and updating when new validated evidence becomes available.

    Preoperative serum alpha-fetoprotein levels can have predictive value for hepatocellular carcinoma survival. Our aim was to analyze the correlation between preoperative serum alpha-fetoprotein levels and survival, following the surgical treatment of hepatocellular carcinoma. Nineteen patients were prospectively followed (07/2005-01/2016). An ROC curve was created to determine the sensitivity and specificity of alpha-fetoprotein in relation to survival (Kaplan-Meier). Of the 19 patients evaluated, 57.9% were men. The mean patient age was 68.1 ± 8.5 years and survival at 1, 3, and 5 years was 89.4, 55.9, and 55.9%. The alpha-fetoprotein cutoff point was 15.1 ng/ml (sensitivity 100%, specificity 99.23%). Preoperative alpha-fetoprotein levels below 15.1, 200, 400, and 463 ng/ml correlated with better 1 and 5-year survival rates than levels above 15.1, 200, 400, and 463 ng/ml (P<.05). Elevated preoperative serum alpha-fetoprotein levels have predictive value for hepatocellular carcinoma survival. Copyright © 2017 Asociación Mexicana de Gastroenterología.

    To assess the preoperative serum levels of CA 125 with its diagnostic role and to evaluate the p53 expression in patients of primary ovarian neoplasms. We also wished to judge their relationship with other parameters like clinical staging and histopathologic tumor type. The present study was conducted on 86 patients during the study period of 2.5 years. Preoperative CA 125 levels were evaluated by an automated immunoassay analyzer. p53 expression was judged immunohistochemically with pre-diluted monoclonal antibody. An objective scoring was done depending on distinct nuclear immunopositivity. Median value of preoperative CA 125 levels was 32 U/mL in benign surface epithelial-stromal tumors (BSEST), 53 U/mL in borderline surface epithelial-stromal tumors (BOT), 346 U/mL in malignant surface epithelial-stromal tumors (MSEST) and 560 U/mL in serous adenocarcinomas (SAC). Most of ovarian tumors were in the FIGO stage I (64 cases, 74.4%), but higher stages (II, III, IV) were observed mostly in MSESTs. SACs displayed the maximum p53 expression. Considering the cut-off value of more than 35 U/mL in CA 125 levels, the sensitivity to diagnose MSESTs was 94.7%. Preoperative CA 125 levels strongly and positively correlated with FIGO staging and p53 expression. Similarly p53 expression strongly and positively correlated with FIGO staging and histopathological categories. Higher values of preoperative CA 125 levels and higher expression p53 are associated with MSESTs and BOTs especially of serous type. They strongly correlate with each other and with tumor stage. But there is no serum CA 125 concentration that can clearly differentiate benign and malignant ovarian masses.

    Laparoscopic radical prostatectomy (LARP) may cause stress urinary incontinence (SUI). This study reports the effects of preoperative pelvic floor muscle therapy (PFMT) on SUI and quality of life (QoL) in men undergoing LARP. In this single-center randomized controlled trial, 122 patients undergoing LARP were assigned to an intervention group of PFMT with biofeedback once a week preoperatively, with 4 weeks' follow-up or to a control group receiving standard care. Randomization and allocation to the trial group were carried out by a central computer system. The primary analysis was based on 121 (n = 65; n = 56), comparing SUI rates and QoL in the two groups in a 1-year follow-up. Validated questionnaires, the Pelvic Floor Inventories (PeLFls), the King's Health Questionnaire (KHQ), the International Prostate Symptom Score (IPSS), a bladder diary, a 24-hr pad test and pelvic floor examination were used. Continence was defined as no leakage at all. All analyses were performed according to intention-to-treat. One hundred twenty-two patients were randomized, 19 patients were excluded from analysis because of early drop-out. There were no significant differences between both groups in the incidence of SUI and QoL based on the KHQ, IPSS, and pad tests (P ≥ 0.05). In all patients continence was achieved in 77.2% at 1 year postoperatively. Preoperative PFMT does not appear to be effective in the prevention of SUI and QoL following LARP. © 2014 Wiley Periodicals, Inc.

    Preoperative analysis in rhinoplasty consists in analyzing individual anatomical and functional characteristics without losing sight of the initial requirements of the patient to which priority should be given. The examination is primarily clinical but it also uses preoperative photographs taken at specific accurate angles. Detecting functional disorders or associated general pathologies, which will reduce the risk of complications. All of these factors taken into account, the surgeon can work out a rhinoplasty plan which he or she will subsequently explain to the patient and obtain his or her approbation.

    Neurological diseases are prevalent in the general population, and the neurohospitalist has an important role to play in the preoperative planning for patients with and at risk for developing neurological disease. The neurohospitalist can provide patients and their families as well as anesthesiologists, surgeons, hospitalists, and other providers guidance in particular to the patient’s neurological disease and those he or she is at risk for. Here we present considerations and guidance for the neurohospitalist providing preoperative consultation for the neurological patient with or at risk of disturbances of consciousness, cerebrovascular and carotid disease, epilepsy, neuromuscular disease, and Parkinson disease.

  9. Music interventions for preoperative anxiety.

    2013-06-06

    Patients awaiting surgical procedures often experience significant anxiety. Such anxiety may result in negative physiological manifestations, slower wound healing, increased risk of infection, and may complicate the induction of anaesthesia and impede postoperative recovery. To reduce patient anxiety, sedatives and anti-anxiety drugs are regularly administered before surgery. However, these often have negative side effects and may prolong patient recovery. Therefore, increasing attention is being paid to a variety of non-pharmacological interventions for reduction of preoperative anxiety such as music therapy and music medicine interventions. Interventions are categorized as 'music medicine' when passive listening to pre-recorded music is offered by medical personnel. In contrast, music therapy requires the implementation of a music intervention by a trained music therapist, the presence of a therapeutic process, and the use of personally tailored music experiences. A systematic review was needed to gauge the efficacy of both music therapy and music medicine interventions for reduction of preoperative anxiety. To examine the effects of music interventions with standard care versus standard care alone on preoperative anxiety in surgical patients. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 7), MEDLINE (1950 to August 2012), CINAHL (1980 to August 2012), AMED (1985 to April 2011; we no longer had access to AMED after this date), EMBASE (1980 to August 2012), PsycINFO (1967 to August 2012), LILACS (1982 to August 2012), Science Citation Index (1980 to August 2012), the specialist music therapy research database (March 1 2008; database is no longer functional), CAIRSS for Music (to August 2012), Proquest Digital Dissertations (1980 to August 2012), ClinicalTrials.gov (2000 to August 2012), Current Controlled Trials (1998 to August 2012), and the National Research Register (2000 to September 2007).

    PubMed

    Clevenger, B; Richards, T

    2015-01-01

    Pre-operative anaemia is a relatively common finding, affecting a third of patients undergoing elective surgery. Traditionally associated with chronic disease, management has historically focused on the use of blood transfusion as a solution for anaemia in the peri-operative period. Data from large series now suggest that anaemia is an independent risk associated with poor outcome in both cardiac and non-cardiac surgery. Furthermore, blood transfusion does not appear to ameliorate this risk, and in fact may increase the risk of postoperative complications and hospital length of stay. Consequently, there is a need to identify, diagnose and manage pre-operative anaemia to reduce surgical risk. Discoveries in the pathways of iron metabolism have found that chronic disease can cause a state of functional iron deficiency leading to anaemia. The key iron regulatory protein hepcidin, activated in response to inflammation, inhibits absorption of iron from the gastrointestinal tract and further reduces bioavailability of iron stores for red cell production. Consequently, although iron stores (predominantly ferritin) may be normal, the transport of iron either from the gastrointestinal tract or iron stores to the bone marrow is inhibited, leading to a state of 'functional' iron deficiency and subsequent anaemia. Since absorption from the gastrointestinal tract is blocked, increasing oral iron intake is ineffective, and studies are now looking at the role of intravenous iron to treat anaemia in the surgical setting. In this article, we review the incidence and impact of anaemia on the pre-operative patient. We explain how anaemia may be caused by functional iron deficiency, and how iron deficiency anaemia may be diagnosed and treated.

    Esophageal cancer is an aggressive malignancy with increasing incidence, and the prognosis of patients treated by surgery alone remains dismal. Preoperative treatment can modestly prolong overall survival. Preoperative chemotherapy or chemoradiation is the standard of care for resectable esophageal cancer (greater than clinical stage I and less than clinical stage IV). One of the challenges is to predict complete response in the surgical specimen from preoperative therapy and to avoid surgery in some patients but also predict ineffectiveness of preoperative therapy if the tumor is resistant and avoid such therapies altogether. In-depth understanding of the molecular biology could lead to personalized therapy, and in the future, clinical trials designed according to molecular features are expected. Here, we summarize preoperative treatment for esophageal adenocarcinoma and their potential. PMID:28491289

    The use of enteral formulas with immunonutrients in patients with gastrointestinal malignancies susceptible to surgery can reduce postoperative morbidity, at the expense of reduced infectious complications, with the consequent reduction in hospital stay and health care costs. Prospective randomized study. 84 patients operated on a scheduled basis for resectable colorectal cancer were recruited. In the group YES IN Impact © Oral was administered for 8 days (3 sachets a day), compared with the NOT IN group who did not receive it. 40.5% (17) patients without immunonutrition suffered infectious complications vs. 33.3% (14) of YES IN. In patients with rectal cancer NOT IN, 50% (8) suffered minor infectious complications (p=.028). In each group (YES IN, NOT IN, colon and rectal cancer) when infectious complications were observed, the variables total hospital stay and costs doubled, with significant differences. These variables showed higher values in the group NOT IN compared with those who received immunonutrition, although these differences were not statistically significant. NOT IN patients suffered infectious complications more frequently than YES IN, with significant results in the subgroup of patients with rectal cancer. The total hospital stay and costs were slightly higher in the group not supplemented, doubling in each category significantly (YES IN, NOT IN, colon and rectal cancer), when infectious complications were observed.

    Postoperative pulmonary complications (PPCs) are common after major non-thoracic surgery and associated with significant morbidity and high cost of care. A number of risk factors are strong predictors of PPCs. The overall goal of the preoperative pulmonary evaluation is to identify these potential, patient and procedure-related risks and optimize the health of the patients before surgery. A thorough clinical examination supported by appropriate laboratory tests will help guide the clinician to provide optimal perioperative care. Copyright © 2016 Elsevier Inc. All rights reserved.

    The perioperative morbidity of diabetic patients is related to preoperative end-organ damage. Due to the microvascular pathology, autonomic neuropathy is common and cardiovascular abnormalities such as hypertension, painless myocardial ischemia, and orthostatic hypotension may predispose patients to perioperative cardiovascular instability. Autonomic dysfunction also contributes to delayed gastric emptying, and preoperative administration of a histamine antagonist and a gastric emptying agent is needed. Chronic hyperglycemia leads to glycosylation of tissue proteins and the accumulation of abnormal collagen can cause stiff joint syndrome resulting in difficult tracheal intubation. The primary goal of pre and intraoperative blood glucose control is to avoid hypoglycemia and ketosis. Moreover, the tight glycemic control has been reported to improve survival in critically ill patients who were treated in the intensive care unit.

    2017-03-01

    The number of patients undergoing revision surgery following failure of anterior cruciate ligament (ACL) reconstruction has increased over the recent past, following the overall increased number of primary ACL reconstruction performed. Failure of primary ACL reconstruction can be attributed to technical errors, biological failures, or new traumatic injuries. Technical errors include femoral and/or tibial tunnels malposition, untreated associated ligaments insufficiencies, uncorrected lower limb malalignment, and graft fixation failures. Candidates for revision surgery should be carefully selected, and the success of ACL revision requires precise preoperative planning to obtain successful results. Preoperative planning begins with the analysis of the mechanisms of ACL reconstruction failure, and information regarding previous surgery, such as the type of graft implanted, and the position of existing hardware. Appropriate imaging is necessary to evaluate the position of the femoral and tibial tunnels, and abnormal tunnel widening. On the basis of clinical examination and imaging, surgeon can perform an ACL revision procedure in 1 or 2 stages.

    BACKGROUND Routine preoperative testing is not recommended for patients undergoing cataract surgery, because testing neither decreases adverse events nor improves outcomes. We sought to assess adherence to this guideline, estimate expenditures from potentially unnecessary testing, and identify patient and health care system characteristics associated with potentially unnecessary testing. METHODS Using an observational cohort of Medicare beneficiaries undergoing cataract surgery in 2011, we determined the prevalence and cost of preoperative testing in the month before surgery. We compared the prevalence of preoperative testing and office visits with the mean percentage of beneficiaries who underwent tests and had office visits during the preceding 11 months. Using multivariate hierarchical analyses, we examined the relationship between preoperative testing and characteristics of patients, health system characteristics, surgical setting, care team, and occurrence of a preoperative office visit. RESULTS Of 440,857 patients, 53% had at least one preoperative test in the month before surgery. Expenditures on testing during that month were $4.8 million higher and expenditures on office visits $12.4 million higher (42% and 78% higher, respectively) than the mean monthly expenditures during the preceding 11 months. Testing varied widely among ophthalmologists; 36% of ophthalmologists ordered preoperative tests for more than 75% of their patients. A patient’s probability of undergoing testing was associated mainly with the ophthalmologist who managed the preoperative evaluation. CONCLUSIONS Preoperative testing before cataract surgery occurred frequently and was more strongly associated with provider practice patterns than with patient characteristics.

    Anxiety is common in surgical patients, with an incidence of 60% to 92%. There is little information on the incidence and severity of preoperative anxiety in patients scheduled for neurosurgery. The aim of this study was to measure the level of preoperative anxiety in neurosurgical patients and to assess any influencing factors. After the Institutional Review Board approval and informed written consent, 100 patients booked for neurosurgery were interviewed preoperatively. Each patient was asked to grade their preoperative anxiety level on a verbal analog scale, Amsterdam Preoperative Anxiety and Information Scale, and a set of specific anxiety-related questions. The anxiety scores and the responses to the questions were compared between the sex, age, weight, diagnosis, and history of previous surgery. The mean age (+/-SD) was 50+/-13 years. The preoperative diagnosis was tumor (n=64), aneurysm (n=14), and other (n=22). Overall verbal analog scale was 5.2+/-2.7; the score was higher for female (5.8+/-2.8) than male patients (4.6+/-2.5) (P<0.05). Amsterdam Preoperative Anxiety and Information Scale anxiety and knowledge scores were greater for surgery than for anesthesia. Questionnaire results showed that the most common anxieties were waiting for surgery, physical/mental harm, and results of the operation. In conclusion, our study showed that neurosurgical patients have high levels of anxiety, with a higher incidence in females. There was a moderately high need for information, particularly in patients with a high level of preoperative anxiety.

    This paper is a report of a study to examine nurses' perceptions of the importance of providing preoperative information to ambulatory surgical patients, and factors that might influence their provision of such teaching. Ambulatory surgery is now widespread and creates a challenge for nurses to provide preoperative teaching in the limited contact time they have with patients. Although nurses act as key educators in patient teaching, little is known about their perceptions of the importance of preoperative teaching, or about current practice in the provision of such teaching for ambulatory surgical patients. A self-administered questionnaire including demographics and the Preoperative Teaching Questionnaire was completed by 91 of the 169 eligible nurses (response rate 53.8%) working in day-surgery units, operating theatres or outpatient clinics providing ambulatory surgery services in two public hospitals in Hong Kong in 2005. A discrepancy between nurses' perceptions and practice in relation to the provision of preoperative information was found. Limited teaching aids, tight operation schedules and language barriers affected the delivery of preoperative information to ambulatory surgical patients. The results highlight the importance of reviewing current preoperative teaching methods and improving the effectiveness of such teaching to enhance the quality of care for ambulatory surgical patients.

    Background A comprehensive preoperative evaluation is critical for providing anesthetic care for patients from the intensive care unit (ICU). There has been no preoperative evaluation form specific for ICU patients that allows for a rapid and focused evaluation by anesthesia providers, including junior residents. In this study, a specific preoperative form was designed for ICU patients and evaluated to allow residents to perform the most relevant and important preoperative evaluations efficiently. Methods The following steps were utilized for developing the preoperative evaluation form: 1) designed a new preoperative form specific for ICU patients; 2) had the form reviewed by attending physicians and residents, followed by multiple revisions; 3) conducted test releases and revisions; 4) released the final version and conducted a survey; 5) compared data collection from new ICU form with that from a previously used generic form. Each piece of information on the forms was assigned a score, and the score for the total missing information was determined. The score for each form was presented as mean ± standard deviation (SD), and compared by unpaired t test. A P value < 0.05 was considered statistically significant. Results Of 52 anesthesiologists (19 attending physicians, 33 residents) responding to the survey, 90% preferred the final new form; and 56% thought the new form would reduce perioperative risk for ICU patients. Forty percent were unsure whether the form would reduce perioperative risk. Over a three month period, we randomly collected 32 generic forms and 25 new forms. The average score for missing data was 23 ± 10 for the generic form and 8 ± 4 for the new form (P = 2.58E-11). Conclusions A preoperative evaluation form designed specifically for ICU patients is well accepted by anesthesia providers and helped to reduce missing key preoperative information. Such an approach is important for perioperative patient safety. PMID:23853741

    INTRODUCTION Fundoplication for laryngopharyngeal disease with oesophageal dysmotility has led to mixed outcomes. In the presence of preoperative dysphagia and oesophageal dysmotility, this procedure has engendered concern in certain regards. METHODS This paper describes a consecutive series of laryngopharyngeal reflux (LPR) patients with a high frequency of dysmotility. Patients were selected for surgery with 24-hour dual channel pH monitoring, oesophageal manometry and standardised reflux scintigraphy. RESULTS Following careful patient selection, 33 patients underwent fundoplication by laparoscopy. Surgery had high efficacy in symptom control and there was no adverse dysphagia. CONCLUSIONS Evidence of proximal reflux can select a group of patients for good results of fundoplication for atypical symptoms.

Preoperative transfusion versus no preoperative transfusion Two trials (434 participants) compared a preoperative transfusion plus standard care to a group receiving standard care. Overall, the quality of the evidence was low to very low across different outcomes according to GRADE methodology. This was due to the trials being at high risk of bias due to lack of blinding, and outcome estimates being imprecise. One trial was stopped early because more people in the no transfusion arm developed an acute chest syndrome. There was no difference in all-cause mortality between people receiving preoperative transfusions and those receiving no preoperative transfusions (two trials, 434 participants, no deaths occurred). There was significant heterogeneity between the two trials in the number of people developing an acute chest syndrome, a meta-analysis was therefore not performed. One trial showed a reduced number of people developing acute chest syndrome between people receiving preoperative transfusions and those receiving no preoperative transfusions, risk ratio 0.11 (95% confidence interval 0.01 to 0.80) (65 participants), whereas the other trial did not, risk ratio 4.81 (95% confidence interval 0.23 to 99.61) (369 participants).

It is associated with increased peri-operative allogeneic blood transfusions, longer hospital lengths of stay and increased morbidity and mortality. Iron deficiency is one of the most common causes of this anaemia. Oral iron therapy has traditionally been used to treat anaemia but newer, safer parenteral iron preparations have been shown to be more effective in other conditions such as inflammatory bowel disease, chronic heart failure and post-partum haemorrhage. A limited number of studies look at iron therapy for the treatment of pre-operative anaemia. The aim of this Cochrane review is to summarise the evidence for use of iron supplementation, both enteral and parenteral, for the management of pre-operative anaemia. The objective of this review is to evaluate the effects of pre-operative iron therapy (enteral or parenteral) in reducing the need for allogeneic blood transfusions in anaemic patients undergoing surgery. We ran the search on 25 March 2015. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic and EMBASE (Ovid), CINAHL Plus (EBSCO), PubMed, clinical trials registries, conference abstracts, and we screened reference lists. We included all randomised controlled trials (RCTs) which compared pre-operative iron monotherapy to placebo, no treatment, standard of care or another form of iron therapy for anaemic adults undergoing surgery. Anaemia was defined by haemoglobin values less than 13 g/dL for males and 12 g/dL for non-pregnant females. Data were collected by two authors on the proportion of patients who receive a blood transfusion, amount of blood transfused per patient (units) and haemoglobin measured as continuous variables at pre-determined time-points: pre

    Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR assessment of prognostic factors prior to therapy has been found to be of value in assessing treatment modalities and outcomes that are targeted to these preoperative prognostic subgroups and in providing a quantifiable assessment of the efficacy of particular chemoradiation treatment protocols by comparing pre-treatment MR staging with post therapy histology assessment. At present, we are focused on achieving clear surgical margins of excision (CRM) to avoid local recurrence. We recommend that all patients with rectal cancer should undergo pre-operative MRI staging. Of these, about half will have good prognosis features (T1-T3b, N0, EMVI negative, CRM clear) and may safely undergo primary total mesorectal excision. Of the remainder, those with threatened or involved margins will certainly benefit from pre-operative chemoradiotherapy with the aim of downstaging to permit safe surgical excision. In the future, our ability to recognise features predicting distant failure, such as extramural vascular invasion (EMVI) may be used to stratify patients for neo-adjuvant systemic chemotherapy in an effort to prevent distant relapse. The optimal pre-operative treatment regimes for these patients (radiotherapy alone, systemic chemotherapy alone or combination chemo-radiotherapy) is the subject of current and future trials.

    Surgery and anaesthesia are significant sources of anxiety for children. In the preoperative period, reducing anxiety helps in preventing the negative consequences that may occur after surgery. The predetermined high-risk children in terms of the development of anxiety play an important role in reducing the negative consequences. Recently featured approaches are modelling and coping techniques, although many techniques are used in the preoperative psychological preparation. The use of computer programs in this area may facilitate important achievements, and it needs to support new studies to be performed. PMID:27366525

    ABSTRACT Objective: To identify pediatric caregivers' reactions in outpatient surgery settings. Methods: A quantitative descriptive/exploratory survey-based study involving application of a semi-structured questionnaire to 62 caregivers in two hospitals. Results: Most caregivers (88.7%) were mothers who submitted to preoperative fasting with their children. Nervousness, anxiety and concern were the most common feelings reported by caregivers on the day of the surgery. Conclusion: Medical instructions regarding preoperative procedures had significant positive impacts on patient care, and on patient and caregiver stress levels. PMID:27759831

    Preoperative anxiety is a common and poorly evaluated condition in patients who will undergo an anesthetic and surgical intervention. The objective of this study was to determine the prevalence of anxiety in a group of patients undergoing elective surgery, as assessed by the Amsterdam Anxiety Preoperative and Information (AAPI) scale. We studied 135 patients scheduled for elective surgery applying the AAPI scale 24 h before the surgical procedure to evaluate the presence of anxiety and patient characteristics. A descriptive analysis with mean +/- standard deviation for categorical variables was done. For intragroup differences, chi(2) test was used. Pearson correlation for the association between anxiety and postoperative complications was carried out. A value of p =0.05 was considered significant. One hundred six patients were surgically treated, 88% were female (average age 44 +/- 12 years). Some degree of preoperative anxiety was present in 72 patients (76%; p = 0.001) with a grade point average on the AAPI scale equal to 17 +/- 7 points, of which 95 (70%, OR = 5.08; p = 0.002) were females. Results of this study suggest the presence of high levels of preoperative anxiety in patients scheduled for elective surgery. The origin of the anxiety appears to be related to many factors that can be evaluated in pre-anesthetic consultation. Further study is needed to prevent the presence of this disorder.

    A recent international consensus conference on the reduction in mortality in cardiac anesthesia and intensive care included intraoperative aortic balloon pump among the ancillary (i.e. non-surgical) drugs/techniques/strategies that might influence survival rates in patients undergoing cardiac surgery. The consensus conferences state that "Pre-operative intraoperative aortic balloon pump might reduce 30-day mortality in elective high risk patients undergoing coronary artery bypass surgery unless specifically contraindicated". The authors of this "expert opinion" presents their insights into the use of the preoperative intraoperative aortic balloon pump and conclude that based on available limited randomized controlled trials and clinical experience preoperative intraoperative aortic balloon pump saves lives in unstable patients.

    Use of vitamin K antagonists creates a risk for patient health and safety. The Dutch framework “Nationwide Standard Integrated Care of Anticoagulation” propagates a shared plan and responsibility by surgeon and anesthesiologist together in the preoperative setting. In our institution, this framework had not been implemented. Therefore, a quality-improvement project was started at the Anesthesia Department to improve perioperative safety. After exploration of barriers, multiple interventions were carried out to encourage co-workers at the preoperative screening department to take shared responsibility: distribution of prints, adjustments in electronic patient records, introduction of a protocol and education sessions. Efficacy was measured retrospectively performing a before-after study collecting perioperative data of patients using vitamin K antagonists. The primary outcome measure was the percentage of predefined safe preoperative plans. Secondary outcome measures were (1) incidence of postoperative bleeding and thrombo-embolic events within the first 24 hours after intervention and (2) necessity to preoperative correction of anticoagulation. Before intervention 72 (29%) safe, 93 (38%) partially unsafe and 83 (33%) unsafe arrangements were made. After the intervention these numbers were 105 (80%), 23 (17%) en 4 (3%), respectively: a significant 51% increase in safe preoperative plans (P<0.001). We observed no significant difference (P=0.369) regarding bleeding and thrombo-embolic events: pre-intervention 12 (5%) cases of postoperative bleeding were documented, vs. 6 (5%) post intervention and the number of thrombo-embolic events was 5 (2%) vs. 0. Also, no significant differences concerning preoperative correction of anticoagulation were observed: 11 (4%) vs. 8 (6%) (P=0.489). This quality improvement project demonstrates a major improvement in safer preoperative arrangements in our institution regarding vitamin K antagonists, using the described interventions

    Preoperative vascular mapping increase rate of successful hemodialysis vascular access operation. Several studies recommend using this procedure routinely. But some studies recommend using this procedure in selected patients. So this study aims to determine the impacts of preoperative vascular mapping in unfavorable-examined patients. 55 patients were studied retrospectively from August 2006 to October 2009. Before April 2008, the operative plans were based on physical examination (group 1). After April 2008, the surgeon did preoperative vascular mapping prior to the operation in unfavorable-examined patients (group 2). The results were compared. There were high maturation rates in favorable-examined patients. In unfavorable-examined patients, preoperative vascular mapping can identified nonpalpable favorable vein which successful maturation of 18.75%. Complementary duplex scan decrease rate of unsuccessful operation significantly (p = 0.037) but does not increase maturation rate. Careful physical examination is important part before operation. Preoperative vascular mapping has benefit only in patients with unfavorable-examined patients. It finds some nonpalpable favorable vein and decrease unsuccessful exploration.

    Haemodialysis treatment requires reliable vascular access. Optimal access is provided via functional arteriovenous fistula (fistula), which compared with other forms of vascular access, provides superior long-term patency, requires few interventions, has low thrombosis and infection rates and cost. However, it has been estimated that between 20% and 60% of fistulas never mature sufficiently to enable haemodialysis treatment. Mapping blood vessels using imaging technologies before surgery may identify vessels that are most suitable for fistula creation. We compared the effect of conducting routine radiological imaging evaluation for vascular access creation preoperatively with standard care without routine preoperative vessel imaging on fistula creation and use. We searched Cochrane Kidney and Transplant's Specialised Register to 14 April 2015 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. We included randomised controlled trials (RCTs) that enrolled adult participants (aged ≥ 18 years) with chronic or end-stage kidney disease (ESKD) who needed fistulas (both before dialysis and after dialysis initiation) that compared fistula maturation rates relating to use of imaging technologies to map blood vessels before fistula surgery with standard care (no imaging). Two authors assessed study quality and extracted data. Dichotomous outcomes, including fistula creation, maturation and need for catheters at dialysis initiation, were expressed as risk ratios (RR) with 95% confidence intervals (CI). Continuous outcomes, such as numbers of interventions required to maintain patency, were expressed as mean differences (MD). We used the random-effects model to measure mean effects. Four studies enrolling 450 participants met our inclusion criteria. Overall risk of bias was judged to be low in one study, unclear in two, and high in one.There was no significant differences in the number of fistulas that were successfully created (4

    The FFTF will become operational with criticality early in 1980. This facility is composed of the test reactor, fuel examination cells, expended fuel storage systems and fuel handling systems. The reactor and storage systems are sodium-cooled with the heat load dumped to the ambient air through heat exchangers. In order to assure that the operation of the FFTF has minimal impact on the environment, a monitoring program has been established. Prior to operation of a new facility, a preoperational environmental survey is required. It is the purpose of this report to briefly describe the environmental survey program and to provide the background data obtained during the preoperational phase of the survey program. Nine stations in the program of particular importance to FFTF are discussed in detail with results of monitoring given. No unexplained trends were noted.

    Anesthesiology societies have issued various guidelines on preoperative fasting since 1990, not only to decrease the incidence of lung aspiration and anesthetic morbidity, but also to increase patient comfort prior to anesthesia. Some of these societies have been updating their guidelines, as such that, since 2010, we now have 2 evidence-based preoperative fasting guidelines available. In this article, an attempt is made to review these updated guidelines, as well as the current instructions for more controversial patients such as infants, the obese, and a particular type of ophthalmic surgery.

    2015-06-01

    Hemoglobin optimization and treatment of preoperative anemia in surgery with a moderate to high risk of surgical bleeding reduces the rate of transfusions and improves hemoglobin levels at discharge and can also improve postoperative outcomes. To this end, we need to schedule preoperative visits sufficiently in advance to treat the anemia. The treatment algorithm we propose comes with a simple checklist to determine whether we should refer the patient to a specialist or if we can treat the patient during the same visit. With the blood count test and additional tests for iron metabolism, inflammation parameter and glomerular filtration rate, we can decide whether to start the treatment with intravenous iron alone or erythropoietin with or without iron. With significant anemia, a visit after 15 days might be necessary to observe the response and supplement the treatment if required. The hemoglobin objective will depend on the type of surgery and the patient's characteristics.

    The objective of this study was to define how preoperative nutritional face-to-face counseling on child's fasting affects parental knowledge, preoperative need-for-information, and anxiety, in pediatric ambulatory tonsillectomy. The participants in the prospective, randomly allocated study were parents (intervention 62/control 62) with children (4-10 years) admitted for ambulatory tonsillectomy. Data were collected by the knowledge test designed for the study and with The Amsterdam preoperative anxiety and information scale (APAIS). The intervention group was invited to a preoperative visit to receive written and verbal face-to-face counseling. They were initiated into the child's active preoperative nutrition. The parents of the control group received current information without face-to-face counseling. The parents followed the instructions. Their knowledge about the child's fast increased (p=0.003), and need-for-information and anxiety decreased (p<0.0001) significantly. The preoperative face-to-face counseling with written information improves parental knowledge about the child's fasting and active preoperative nutrition, and relieves their need-for-information and anxiety. The primary responsibility remains with the health care professionals when the active preoperative nutrition of the child and counseling on it are introduced into nursing practice.

    2008-05-01

    The preoperative evaluation serves several purposes for the gynecologist. Patients with previously undiagnosed, or incompletely managed, medical concerns are identified and appropriate treatment initiated. In women with known medical concerns, the surgeon can anticipate problems and plan for appropriate postoperative care. In certain cases, the preoperative evaluation identifies medical conditions that are unstable enough to adversely affect the postoperative outcome, and appropriate referral for medical management can be made. One of the most important aspects of the evaluation is the identification of women at high risk for cardiovascular complications. A stepwise approach is useful to identify those women who may proceed to surgery and those who need further testing. Much of the preoperative evaluation of the woman with pulmonary disease can be done during the history and physical examination without additional testing. Deep venous thrombosis is a significant concern in gynecologic surgery; appropriate identification of the woman at risk is important, with initiation of prophylaxis occurring shortly after the surgery concludes. Many women undergoing gynecologic surgery have diabetes. Careful management of diabetes in the perioperative period has become more germane, with evidence of improved outcomes as tight control is achieved. Much of the preoperative evaluation falls easily into the purview of the gynecologist, with advice presented as to when medical consultation should be considered.

We will try to review the current literature dealing with the recommendations about withdrawing or continuing these drugs.

  1. Do psychological interventions reduce preoperative anxiety?

    PubMed

    Renouf, Tessa; Leary, Alison; Wiseman, Theresa

    The systematic review investigates whether, during preoperative assessments, nurse-delivered psychological interventions reduce anxiety levels preoperatively for patients undergoing elective surgery. Seventeen studies met the inclusion criteria for data extraction and in-depth critiquing. Of these, two were discarded due to lack of validity, while the remaining studies were organised thematically in a narrative synthesis, generating two principal results: patients' preoperative anxieties were lowered by nurse-delivered general preoperative psychological interventions; and patients valued individualised preoperative interventions delivered by nurses. However, the single oncology study in the review showed an elevation in preoperative anxiety, regardless of intervention, and highlights the need for more research in this under-reviewed area. In the meantime, the authors believe that service improvements should be implemented to ensure that, where possible, psychological preoperative interventions are individualised.

    Awake surgery emerges as a standard of care for brain tumors located in or near eloquent areas. Levels of preoperative anxiety in patients are important, because anxiety can influence cognitive performance and participation, hence altering the outcome of the procedure. In this study we analyzed the prevalence and potential clinical predictors of anxiety in the pre-operative phase of an awake brain tumor surgery. Seventy consecutive candidates for an awake brain tumor surgery were included. All patients received a neuropsychological pre-operative work-up. The Hospital Anxiety and Depression Scale (HADS) was administrated to investigate symptoms of anxiety. Demographic and medical data were extracted from patients' charts. Linear regression analyses, multiple regression analyses, t-tests for parametric and Mann-Whitney U tests for non-parametric data were used to analyze the relation between demographic and medical variables and pre-operative anxiety. Mean score on the anxiety scale of the HADS was 6.1 (SD=4.2, range 1-19) and 25% of the patients scored on or above the cut-off for anxiety symptoms (score >7). Women reported higher levels of anxiety than men (p<0.01). Furthermore, younger patient were more anxious than older patients (p<0.05). No other variables were significantly related to pre-operative anxiety. Merely, one in every four patients reported significant anxiety symptoms in the pre-operative phase. Besides gender and age, none of the other demographic or medical factors were significantly associated with the level of anxiety. Copyright © 2017 Elsevier B.V. All rights reserved.

    We studied the effect of preoperative determinants on early outcomes of 1028 consecutive infant heart operations in a limited-resource setting. Comprehensive data on pediatric heart surgery (January 2010-December 2012) were collected prospectively. Outcome measures included in-hospital mortality, prolonged ventilation (>48 hours), and bloodstream infection (BSI) after surgery. Preoperative variables that showed significant individual association with outcome measures were entered into a logistic regression model. Weight at birth was low in 224 infants (21.8%), and failure to thrive was common (mean-weight Z score at surgery was 2.72 ± 1.7). Preoperatively, 525 infants (51%) needed intensive care, 69 infants (6.7%) were ventilated, and 80 infants (7.8%) had BSI. In-hospital mortality (4.1%) was significantly associated with risk adjustment for congenital heart surgery-1 (RACHS-1) risk category (P < 0.001). Neonatal status, preoperative BSI, and requirement of preoperative intensive care and ventilation had significant individual association with adverse outcomes, whereas low birth weight, prematurity, and severe failure to thrive (weight Z score <-3) were not associated with adverse outcomes. On multivariable logistic regression analysis, preoperative sepsis (odds ratio = 2.86; 95% CI: 1.32-6.21; P = 0.008) was associated with mortality. Preoperative intensive care unit stay, ventilation, BSI, and RACHS-1 category were associated with prolonged postoperative ventilation and postoperative sepsis. Neonatal age group was additionally associated with postoperative sepsis. Although severe failure to thrive was common, it did not adversely affect outcomes. In conclusions, preoperative BSI, preoperative intensive care, and mechanical ventilation are strongly associated with adverse outcomes after infant cardiac surgery in this large single-center experience from a developing country. Failure to thrive and low birth weight do not appear to adversely affect surgical

    The radiologist plays an important role in detection, diagnosis, localization, pathologic correlation, and follow-up imaging of breast cancer. A successful breast surgical treatment program relies on the image guidance tools and skills of the radiologist and surgeon. This article reviews the evolving tools available for preoperative localization. Non-wire devices provide a safe, efficient, noninferior alternative to wire localization and can be placed 0 to 30 days before scheduled surgery. This technology may evolve to other longer-term, efficient, and cost-effective applications for patients who require neoadjuvant treatment or who have findings visible only at MR imaging.

    Because most older adults with hip fractures require urgent surgical intervention, the preoperative medical evaluation focuses on the exclusion of the small number of contraindications to surgery, and rapid optimization of patients for operative repair. Although many geriatric fracture patients have significant chronic medical comorbidities, most patients can be safely stabilized for surgery with medical and orthopedic comanagement by anticipating a small number of common physiologic responses and perioperative complications. In addition to estimating perioperative risk, the team should focus on intravascular volume restoration, pain control, and avoidance of perioperative hypotension. Copyright © 2014 Elsevier Inc.

    Twenty-eight patients were investigated psychologically before surgery. The purposes of the study were (1) to discover the nature of preoperative anxiety, and (2) to compare direct questioning with an indirect method. The merits and shortcomings of the two types of assessment emerged. The findings suggest that, in addition to worries about the operation and the anaesthetic, there was concern about leaving the home and family, which was accentuated by lack of communication and contact with hospital staff, including the surgical team. Pain was found to have a variety of implications including loneliness. These and other findings are discussed in relation to psychological theories. PMID:4819911

    Based on previous studies, we hypothesized that the clinical phenomena of preoperative anxiety, emergence delirium, and postoperative maladaptive behavioral changes were closely related. We examined this issue using data obtained by our laboratory over the past 6 years. Only children who underwent surgery and general anesthesia using sevoflurane/O(2)/N(2)O and who did not receive midazolam were recruited. Children's anxiety was assessed preoperatively with the modified Yale Preoperative Anxiety Scale (mYPAS), emergence delirium was assessed in the postanesthesia care unit, and behavioral changes were assessed with the Post Hospital Behavior Questionnaire (PHBQ) on postoperative days 1, 2, 3, 7, and 14. Regression analysis showed that the odds of having marked symptoms of emergence delirium increased by 10% for each increment of 10 points in the child's state anxiety score (mYPAS). The odds ratio of having new-onset postoperative maladaptive behavior changes was 1.43 for children with marked emergence status as compared with children with no symptoms of emergence delirium. A 10-point increase in state anxiety scores led to a 12.5% increase in the odds that the child would have a new-onset maladaptive behavioral change after the surgery. This finding is highly significant to practicing clinicians, who can now predict the development of adverse postoperative phenomena, such as emergence delirium and postoperative behavioral changes, based on levels of preoperative anxiety.

    Inguinal hernia is one of the most common surgical pathologies in childhood. Any of the abdominal organs can slide into the hernial sac and become incarcerated there. In girls, the fallopian tubes, ovaries, uterus, and-rarely-ovarian cysts can form the sliding component of an inguinal hernia. The aim of this study was to investigate the diagnostic value of preoperative sonographic examination in girls with nonreducible inguinal masses. Nine girls ranging in age from 2 months to 8 years who were admitted to our clinic with nonreducible inguinal masses were included in the study. All patients underwent sonographic examination followed by surgery on the day of admission. A definitive diagnosis was obtained in 6 patients on preoperative sonographic evaluation, whereas 3 patients were misdiagnosed. One patient was diagnosed sonographically as having lymphadenopathy, but surgery revealed an ovarian cyst sliding into the hernial sac. A second patient was found to have an infected lymph node at surgery instead of a strangulated bowel loop as diagnosed on sonographic examination. In the third patient, the preoperative sonographic diagnosis was an ovarian cyst in the hernia sac, but surgery revealed a cyst of the canal of Nuck. Inguinal masses in young girls must be carefully evaluated, because the sonographic preoperative diagnosis may be misleading. (c) 2008 Wiley Periodicals, Inc.

    Background Preoperative anaemia is associated with adverse outcomes after surgery but outcomes after liver surgery specifically are not well established. We aimed to analyze the incidence of and effects of preoperative anemia on morbidity and mortality in patients undergoing liver resection. Methods All elective hepatectomies performed for the period 2005–2012 recorded in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database were evaluated. We obtained anonymized data for 30-day mortality and major morbidity (one or more major complication), demographics, and preoperative and perioperative risk factors. We used multivariable logistic regression models to assess the adjusted effect of anemia, which was defined as (hematocrit <39% in men, <36% in women), on postoperative outcomes. Results We obtained data for 12,987 patients, of whom 4260 (32.8%) had preoperative anemia. Patients with preoperative anemia experienced higher postoperative major morbidity and mortality rates compared to those without anemia. After adjustment for predefined variables, preoperative anemia was an independent risk factor for postoperative major morbidity (adjusted OR 1.21, 1.09–1.33). After adjustment, there was no significant difference in postoperative mortality for patients with or without preoperative anemia (adjusted OR 0.88, 0.66–1.16). Conclusion Preoperative anemia is independently associated with an increased risk of major morbidity in patients undergoing hepatectomy. Therefore, it is crucial to readdress preoperative blood management in anemic patients prior to hepatectomy. PMID:27017165

We herein review the literature concerning preoperative optimization of these patients. Salient findings are that end-organ dysfunction and medication should be optimized before surgery. Specifically: (1) reversible causes of anemia should be treated and a preoperative hemoglobin level of 100 g/L obtained; (2) renal function and volume status should be optimized; (3) liver function must be carefully evaluated; (4) nutritional status should be assessed and cachexia treated to achieve a preoperative albumin level of at least 30 g/L and a body mass index > 20; and (5) medication adjustments performed, such as withholding inhibitors of the renin-angiotensin-aldosterone system before surgery and continuing, but not starting, β-blockers. Levels of natriuretic peptides (brain natriuretic peptide [BNP] and N-terminal proBNP) provide additional prognostic value and therefore should be measured. In addition, individual patient's risk should be objectively assessed using standard formulas such as the EuroSCORE-II or Society of Thoracic Surgeons risk scores, which are simple and validated for various cardiac surgeries, including left ventricular assist device implantation. When patients are identified as high risk, preoperative hemodynamic optimization might be achieved with the insertion of a pulmonary artery catheter and hemodynamic-based tailored therapy. Finally, a prophylactic intra-aortic balloon pump might be considered in certain circumstances to decrease morbidity and even mortality, like in some high risk heart failure patients who undergo cardiac surgery, whereas routine preoperative inotropes are not recommended and should be reserved for patients in shock, except maybe for levosimendan.

    OBJECTIVE Surgical site infections (SSIs) are costly to patients and the health care system. Pediatric neurosurgery SSI risk factors are not well defined. Intraoperative protocols have reduced, but have not eliminated, SSIs. The effect of preoperative intervention is unknown. Using quality improvement methods, a preoperative SSI prevention protocol for pediatric neurosurgical patients was implemented to assess its effect on SSI rate. METHODS Patients who underwent a scheduled neurosurgical procedure between January 2014 and December 2015 were included. Published evidence and provider consensus were used to guide preoperative protocol development. The Model for Improvement was used to test interventions. Intraoperative and postoperative management was not standardized or modified systematically. Staff, family, and overall adherence was measured as all-or-nothing. In addition, SSI rates among eligible procedures were measured before and after protocol implementation. RESULTS Within 4 months, overall protocol adherence increased from 51.3% to a sustained 85.7%. SSI rates decreased from 2.9 per 100 procedures preintervention to 0.62 infections postintervention (p = 0.003). An approximate 79% reduction in SSI risk was identified (risk ratio 0.21, 95% CI 0.08-0.56; p = 0.001). CONCLUSIONS Clinical staff and families successfully collaborated on a standardized preoperative protocol for pediatric neurosurgical patients. Standardization of the preoperative phase of care alone reduced SSI rates. Attention to the preoperative in addition to the intraoperative and postoperative phases of care may lead to further reduction in SSI rates.

    Performing preoperative skin antisepsis to remove soil and microorganisms at the surgical site may help prevent patients from developing a surgical site infection. The updated AORN "Guideline for preoperative skin antisepsis" addresses the topics of preoperative patient bathing and hair removal, selection and application of skin antiseptics, and safe handling, storage, and disposal of skin antiseptics. This article focuses on key points of the guideline to help perioperative personnel develop protocols for patient skin antisepsis. The key points include the need for the patient to take a preoperative bath or shower and the need for perioperative personnel to manage hair at the surgical site, select a safe and effective antiseptic for the individual patient, perform a safe preoperative surgical site prep, and appropriately store skin antiseptics. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures.

    Protein-energy undernutrition, or the possibility of its development, has been documented to occur frequently in surgical patients admitted to hospital. Nutritional status is known to deteriorate over the course of the hospital stay, with poor awareness by medical and nursing staff as to the deleterious effects of impaired nutritional status on clinical outcome and hospital costs. While there is no consensus on the best method for assessment of the nutritional status of surgical patients pre-operatively, there are a number of techniques available. These techniques can be divided into two types, those suitable for screening for nutrition risk on admission to hospital and those used to fully assess nutritional status. Both techniques have their limitations, but if used correctly, and their limitations recognized, should identify the appropriate degree of nutritional intervention for an individual patient in a timely and cost-effective manner. The techniques currently available for nutritional screening and nutritional assessment are reviewed, and their applicability to the Irish setting are discussed in the present paper.

    Preoperative anxiety is prevalent in surgical patients who may require anxiety medications, thus impacting preoperative teaching and patient satisfaction. No studies were found in a comprehensive search on the effect of essential oils on anxiety in the preoperative setting. The purpose of this experimental study was to investigate whether the essential oil lavandin is more effective than standard care in reducing preoperative anxiety. A convenience sample of 150 adult patients were randomly assigned to either control (standard care), experimental (standard care plus essential oil lavandin), or sham (standard care plus jojoba oil) groups. Visual analog scales were used to assess anxiety on admission and OR transfer. Controlling for baseline anxiety and pain, the lavandin group had significantly lower anxiety on OR transfer, suggesting that lavandin is a simple, low-risk, cost-effective intervention with the potential to improve preoperative outcomes and increase patient satisfaction. Future studies should test the effects of lavandin in the postoperative phase and in specific populations with documented high anxiety.

    This study investigated the pathophysiology of preoperative hyponatremia in elderly patients with a large pituitary tumor. The tumor size, initial symptoms, and preoperative pituitary hormonal function were analyzed in 96 patients, consisting of 82 younger than 70 years old (mean age 49.7 years) and 14 older than 70 years old (mean age 72.0 years). There was no difference in tumor size between the two age groups. The initial symptom of all younger patients was visual disturbance. Preoperative hormonal evaluations revealed subclinical panhypopituitarism in four patients (4.9%). Five of the 14 older patients had severe hyponatremia (107-117 mEq/l) based on panhypopituitarism, and four of these five patients showed consciousness disturbance as the initial symptom, initiated by physical and/or psychological stress, or occurrence of intratumoral hemorrhage. Preoperative subclinical panhypopituitarism was found in another patient. The overall occurrence rate of preoperative panhypopituitarism in the older patients was 42.9%. The difference in the frequency of preoperative panhypopituitarism was statistically significant between the two groups. Preoperative severe hyponatremia associated with a large pituitary tumor is characteristic of elderly patients. The number of receptors for adrenocorticotropic hormone in the adrenal cortex decreases during the aging process. Additional physical and/or psychological stress prompts pituitary dysfunction in such patients, causing the manifestation of acute symptoms of adrenal insufficiency based on panhypopituitarism. Primary care using high dose hydrocortisone and electrolyte fluid is critical.

    Preoperative fasting period is required in order to reducing the risk of pulmonary aspiration which may occur during pediatric general anesthesia. Overnight fasting is still prevalent in Japan. Children could be easily dehydrated or have hypoglycemia after such long fasting period. American Society of Anesthesiologists (ASA) issued a simple guideline as "practice guidelines for preoperative fasting and the use of pharmacologic agents to reduce the risk of pulmonary aspiration" in 1999. Cochrane Database evaluated this guideline twice in 2005 and in 2009. In this article, recent tactics of preoperative fasting in children is reviewed along the ASA guideline and the Cochrane report.

    Preoperative definitive diagnosis of intradural lumbar disc herniation (ILDH) is difficult despite the availability of various neuroradiological investigative tools. We present a case of ILDH diagnosed preoperatively by discography and computed tomography-discography (disco-CT).The patient was a 63-year-old man with acute excruciating right leg pain. Discography and disco-CT demonstrated leakage of the contrast medium into the intradural space. Based on these findings, a right L5 nerve root disturbance caused by ILDH was diagnosed. A right L5 hemi-laminectomy and a dorsal durotomy were performed. The herniated disc was carefully dissected and then completely removed. Three months after surgery, the patient had fully recovered. This report highlights the importance of making a definitive diagnosis of ILDH preoperatively for better surgical planning and improved clinical outcomes. Furthermore, discography and disco-CT are both useful preoperative diagnostic tools for the diagnosis of ILDH. PMID:27559461

    Postoperative mortality remains alarmingly high with a mortality rate ranging between 0.4% and 4%. A small subgroup of multimorbid and/or elderly patients undergoing different surgical procedures naturally confers the highest risk of complications and perioperative death. Therefore, preoperative assessment should identify these high-risk patients and stratify them to individualized monitoring and treatment throughout all phases of perioperative care. A "tailored" perioperative approach might help further reduce perioperative morbidity and mortality. This article aims to elucidate individual morbidity-specific risks. It further suggests approaches to detect patients at the risk of perioperative complications.

    The aim of this is study is to determine if preoperative trophic feeds (TFs) can improve outcomes after Norwood palliation. This is a retrospective cohort study. The setting is a pediatric cardiovascular intensive care unit in a tertiary hospital. The patients were 50 consecutive patients with hypoplastic left heart, excluding 5 patients with prematurity or other significant comorbidities. Thirty-one patients that received preoperative TFs (20-30 mL/kg) were compared with 14 that remained nothing by mouth. Decision to initiate feeds was based on attending preference. All patients had protocolized feeds postoperatively, with initiation via transpyloric tube when patient was on minimal inotropes. Demographic, feeding, and other clinical outcome data were collected retrospectively from the patient medical record. There were no differences in demographics or preoperative risk factors (mechanical ventilation and lowest pH) between the two groups. Overall survival to discharge was 78% (25/31 TF, 10/14 nothing by mouth, P = .7). Neonates receiving TFs had less fluid administration in the cardiovascular operating room (P = .002), a more negative 48-hour postoperative fluid balance (P = .03), and median 3 days shorter duration of mechanical ventilation (P = .006). Trophic feeds patients also had a nonsignificant trend toward lower peak lactic acid (P = .06), lower inotropic score (P = .15), shorter hospital length of stay (P = .19), and faster time to tolerance of full enteral and oral feeds by 3 and 8 days, respectively (P = .06 and .01). There were no episodes of necrotizing enterocolitis in either group. Preoperative TFs before Norwood palliation appear safe and are associated with shorter duration of mechanical ventilation, a trend toward more stable postoperative hemodynamics, less fluid overload, and earlier postoperative feeding tolerance. © 2014 Wiley Periodicals, Inc.

    National guidelines do not support preoperative body washing to reduce surgical site infections, instead recommending bathing or showering with soap. Yet preoperative body washing continues to be widely used in many hospitals across Europe. This paper suggests that existing trials of preoperative body washing, upon which guidelines are based, are dated and proposes a new investigation of preoperative body washing using modern definitions of surgical site infection with standardised patient follow up, modern surgical techniques and well designed trials. This paper provides a critique of existing guidelines and describes a randomised trial with 60 participants to compare the effect of soap and two antiseptic washing products on colony forming units (CFUs) for up to six hours. Chlorhexidine gluconate and octenidine were significantly more effective than soap in reducing CFUs in the underarm, and chlorhexidine was significantly more effective than soap in reducing CFUs in the groin.

    We developed and validated a prediction rule for the occurrence of early postoperative severe pain in surgical inpatients, using predictors that can be easily documented in a preoperative setting. A cohort of surgical inpatients (n=1416) undergoing various procedures except cardiac surgery and intracranial neurosurgery in a University Hospital were studied. Preoperatively the following predictors were collected: age, gender, type of scheduled surgery, expected incision size, blood pressure, heart rate, Quetelet index, the presence and severity of preoperative pain, health-related quality of life the (SF-36), Spielberger's State-Trait Anxiety Inventory (STAI) and the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The outcome was the presence of severe postoperative pain (defined as Numeric Rating Scale > or =8) within the first hour postoperatively. Multivariate logistic regression in combination with bootstrapping techniques (as a method for internal validation) was used to derive a stable prediction model. Independent predictors of severe postoperative pain were younger age, female gender, level of preoperative pain, incision size and type of surgery. The area under the receiver operator characteristic (ROC) curve was 0.71 (95% CI: 0.68-0.74). Adding APAIS scores (measures of preoperative anxiety and need for information), but not STAI, provided a slightly better model (ROC area 0.73). The reliability of this extended model was good (Hosmer and Lemeshow test p-value 0.78). We have demonstrated that severe postoperative pain early after awakening from general anesthesia can be predicted with a scoring rule, using a small set of variables that can be easily obtained from all patients at the preoperative visit. Before this internally validated preoperative prediction rule can be applied in clinical practice to support anticipatory pain management, external validation in other clinical settings is necessary.

    Parents feel fear and anxiety before surgery is performed on their child, and those feelings could obstruct their preparation for the surgery. Preoperative information could relieve those feelings. To determine the preoperative information needs of parents of children undergoing elective surgery. A study was conducted on the parents of children who underwent elective surgery. Demographic data of parents were recorded. Preoperative information received or would like to have received was assessed in terms of contents, methods, opportunity, place and informant. Descriptive statistics were used. Thirteen hundred parents were surveyed. More than 80% of them want preoperative information about anaesthesia, surgery, preoperative fasting, drugs and anaesthetic complications, monitoring, intravenous line management, pain treatment, postoperative feeding, anxiety control, hospitalisation room, recovery room, and entertainment in recovery room. Most want to be informed verbally, one to two weeks in advance and not on the same day of surgery. The informant should be the surgeon and in his office. In addition, they want information through leaflets, videos and simulation workshops, or guided tours. Parents need complete preoperative information about anesthesia, surgery and postoperative care, received verbally and in advance. Copyright © 2015 Sociedad Chilena de Pediatría.

  9. Preoperative assessment and planning of haemodialysis vascular access

    PubMed Central

    Lomonte, Carlo; Basile, Carlo

    2015-01-01

    Effective haemodialysis (HD) requires a reliable vascular access (VA). Clinical practice guidelines strongly recommend the arteriovenous fistula (AVF) as the preferred VA in HD patients. The creation of an AVF should be promoted in all eligible patients who choose HD, as it improves outcomes and reduces costs when compared with central venous catheters. Fistula eligibility is a ‘work in progress’. Three steps in order to increase the pool of eligible patients can be individualized: (i) process of care, which includes three fundamental items: the VA team, early VA education and timely VA surgery referral; (ii) preoperative evaluation; (iii) surgical strategy. Nephrologists should be able to play a leading and coordinating role of the VA team. They should design a plan that identifies a sequence of options that can be used to provide adequate renal replacement therapy throughout the life span of every end-stage renal disease patient. The main points of this strategy are (i) early vascular education, in which a ‘save the vein program’ should always be implemented; (ii) timely VA surgery referral and preoperative evaluation: careful examination of arterial and venous beds is mandatory before VA placement; physical examination in addition to colour Doppler ultrasound mapping improves AVF outcomes; (iii) surgical strategy: a successful VA strategy must take into account vascular anatomy, clinical factors and prognosis.

    The management of pain is one of the greatest clinical challenges for nurses who care for patients during the postoperative period. It can be even more challenging for patients who must manage their own pain after discharge from the health care facility. Research shows that postoperative pain continues to be undermanaged despite decades of education and evidence-based guidelines. Ineffective management of postoperative pain can negatively impact multiple patient outcomes. The purpose of this quality improvement project was to evaluate the effectiveness of a preoperative pain management patient education intervention on improving patients' postoperative pain management outcomes. The project was conducted with patients undergoing same-day laparoscopic cholecystectomy in an outpatient general surgery service at a teaching institution. Patients in the intervention and comparison groups completed the American Pain Society Patient Outcome Questionnaire-Revised during their first postoperative clinic visit 2 weeks after surgery. Results showed that patients who received the preoperative education intervention reported less severe pain during the first 24 hours postoperatively, experienced fewer and less severe pain medication side effects, returned to normal activities sooner, and used more nonpharmacologic pain management methods postoperatively compared with those who did not receive the education.

    This study used a theoretical model to determine whether an efficacy-enhancing teaching protocol was effective in improving immediate postoperative behaviors and selected short- and long-term health outcomes in women who underwent abdominal hysterectomies. The model used was the self-efficacy theory of Albert Bandura, PhD. One hundred eight patients in a 486-bed teaching hospital in the Midwest who underwent hysterectomies participated. The participation rate was 85%, and the attrition rate was 17% during the six-month study. The major finding was that participants in the efficacy-enhancing teaching group ambulated significantly longer than participants in the usual care group. This is an important finding because the most prevalent postoperative complications after hysterectomy are atelectasis, pneumonia, paralytic ileus, and deep vein thrombosis, and postoperative ambulation has been shown to decrease or prevent all of these complications. This finding could affect the overall health status of women undergoing hysterectomies.

    To increase the competency of specialist outpatient clinic nurses in the provision of pre-operative total knee replacement (TKR) education, and ensure that all patients scheduled for elective TKR received the pre-operative education package. The project was implemented in three phases. Phase 1 entailed a baseline audit that analysed 30 randomized TKR patients who received pre-operative education. In Phase 2, the gaps and barriers in the project were discussed. Using best practice recommendations from the Joanna Briggs Institute, the project team leader collated and standardized the pre-operative education tools, which consisted of a pictorial booklet, a video and home care advice. A teaching plan guided the nurses to increase their understanding and improve practice using the education tools. The usefulness of education strategies and tools was discussed and these were improved over the proposed timeline. Phase 3 entailed a post-implementation audit to evaluate the provision of pre-operative education. Post implementation, nurses' competency in the provision of pre-operative TKR education increased from 18% to 91%. The number of patients who received the structured pre-operative education package increased from 27% to 50%. Overall, there was improvement in the provision of pre-operative TKR education to patients by clinic nurses using evidence-based best practice and a standardized education package.

  13. Benefits of pre-operative information programmes.

    PubMed

    Garretson, Sharon

    Thousands of patients undergo surgical procedures daily. Research has shown the benefits of giving pre-operative information to patients, which include decreased length of stay, less demand for analgesia post-operatively and increased patient satisfaction. However, despite this evidence, there are still many facilities with no formal policy or programme for giving pre-operative information. Nurses and managers should be made aware of the benefits and potential financial savings of pre-operative information programmes. Once education takes place, a concerted multidisciplinary effort should be made to implement a programme. This will help to ensure that patients no longer arrive at the operating theatre frightened and unaware of what will happen to them.

    An epidermoid cyst arising within an intrapancreatic accessory spleen (ECIAS) is rare, and also difficult to correctly diagnose before surgery. It is mostly misdiagnosed as a cystic tumor, such as a mucinous cystic neoplasm or as a solid tumor with cystic degeneration, such as a neuro endocrine tumor. We herein report a case of ECIAS and also perform a literature review of 35 reports of ECIAS. Although the preoperative diagnosis of ECIAS using conventional imaging is relatively difficult to make, careful preoperative examinations of the features on computed tomography and magnetic resonance imaging could lead to a correct preoperative diagnosis of ECIAS which might thereby reduce the number of unnecessary resections.

    The investigations conducted by the authors enabled them to pinpoint further the complex of symptoms determining a phase character of volemic disturbances in thyrotoxicosis. The phases somewhat reveal the volemic substrate of thyrotoxicosis, allowing an aimed management of some stages of the preoperative preparation. The latter is conventionally divided according to Sh. Milk into three periods: initial, intermediate and final. The main aim of the preoperative correction is to normalize hydration correlations, that is likely to be gained by excreting excessive sodium and replenishment of potassium deficit.

    We compared estimated blood loss (EBL) in patients who underwent surgical excision of carotid body tumors (CBTs) after preoperative superselective angiography with embolization (PSE) with that in patients who underwent excision of CBTs without PSE. We performed a retrospective chart review of a consecutive case series in a single surgeon's practice within an academic tertiary care medical center. Twenty-five patients underwent surgical resection of a CBT from 1989 to 2009. From 1989 to 1996, 10 consecutive patients had PSE of the CBT, whereas the subsequent 15 patients (1996 to 2009) had no PSE. Demographic data including age, sex, and tumor size were collected. The EBL was obtained from intraoperative records and operative notes dictated at the time of surgery. Tumor size was based on preoperative radiographic measurements by a senior radiologist and the surgeon. In the 10 patients with PSE, the mean age was 41 years (range, 22 to 72 years) and the mean tumor size was 4.8 cm (range, 2.9 to 8.3 cm). The mean EBL was 305 mL (range, 50 to 1,000 mL); 2 patients had an EBL of more than 400 mL. In the 15 patients without PSE, the mean age was 43.7 years (range, 20 to 75 years) and the mean tumor size was 4.4 cm (range, 2.8 to 7.9 cm). The mean EBL was 265.6 mL (range, 40 to 900 mL); 2 patients had an EBL of more than 400 mL. There were no significant differences between the 2 groups with regard to age, tumor size, or EBL. Preoperative superselective angiography with embolization of a CBT does not lead to a significant reduction in intraoperative EBL.

    To (1) evaluate the potential for recycling uncontaminated preoperative waste and (2) identify recycling differences within otolaryngology-head and neck surgery subspecialties. Prospective study. Three university-affiliated tertiary level hospitals. Otolaryngology-head and neck surgery operative procedures. A total of 97 operative procedures were evaluated. Preoperative waste products were sorted into recyclable and nonrecyclable materials; intraoperative waste was weighed for volume but not sorted. The preoperative period was defined as the opening of the surgical supply cart for operating room preparation until procedure initiation. Mass and volume of each type of waste were recorded upon the conclusion of the case. Approximately 23.1% of total operative waste mass (36.7% by volume) was derived from the preoperative set-up, of which 89.7% was recyclable. Pediatric procedures produced the least recyclable material per operation as a proportion of total waste, which was statistically different than the 2 highest recyclable subspecialties, general and rhinology (P = .006); the remaining subspecialties did not statistically differ in proportion of recyclable material produced. This study identified a source of clean recyclable materials that could eliminate 21% of operating room waste mass. © American Academy of Otolaryngology-Head and Neck Surgery Foundation 2014.

    Reducing anxiety is very important before operation. Preoperative visit and use of premedication are popular methods to achieve this goal, but the role of anxiolytic premedication remains unclear and postoperative side-effects may result from routine premedication. Citrus aurantium is used as an alternative medicine in some countries to treat anxiety, and recently the anxiolytic role of this medicinal plant was established in an animal model study. The aim of this study was to assess the anxiolytic effect of Citrus aurantium blossomon preoperative anxiety. We studied 60 ASA I patients undergoing minor operation. In a randomized double-blind design, two groups of 30 patients received one of the following oral premedication two hours before induction of anesthesia: 1) Citrus aurantium blossom distillate 1mL.kg(-1) (C-group); 2) Saline solution 1mL.kg(-1) as placebo (P-group). Anxiety was measured before and after premedication using the Spielberger state-trait anxiety inventory (STAI-state) and the Amsterdam preoperative anxiety and information scale (APAIS) before operation. After premedication, both the STAI-state and the APAIS scales were decreased in C-group (p<0.05); while exhibiting no significant changes in P-group. Citrus aurantium blossom may be effective in terms of reduction in preoperative anxiety before minor operation. Copyright © 2011 Elsevier Editora Ltda. All rights reserved.

    Transposition of the great arteries (TGA) requires early surgical repair during the neonatal period. Several preoperative factors have been identified for the postoperative poor outcome after arterial switch operation (ASO). However, the data remain uncertain an association. Therefore, we investigated the preoperative factors which affect the early postoperative outcomes. Between March 2005 and May 2012, a retrospective study was performed which included 126 infants with an ASO for TGA. Preoperative data included the vasoactive inotropic score (VIS) and baseline hemodynamics. Early postoperative outcomes included the duration of mechanical ventilation, the length of stay in the intensive care unit and hospital, and early mortality. Multivariate linear regression and receiver operating characteristics analysis were performed. The duration of mechanical ventilation was significantly correlated with the preoperative mechanical ventilator support and VIS, and CPB time. On multivariate linear regression analysis, a higher preoperative VIS, preoperative B-type natriuretic peptide (BNP) level, and the CPB time were identified as independent risk factors for delayed mechanical ventilation. Preoperative VIS (OR 1.154, 95 % CI 1.024-1.300) and the CPB time (OR 1.034, 95 % CI 1.009-1.060) were independent parameters predicting early mortality. A preoperative VIS of 12.5 had the best combined sensitivity (83.3 %) and specificity (85.3 %) and an AUC of 0.852 (95 % CI 0.642-1.061) predicted early mortality. Our results suggest that preoperative VIS and BNP can predict the need for prolonged postoperative mechanical ventilation. Moreover, preoperative VIS may be used as a simple and feasible indicator for predicting early mortality.

    To identify pediatric caregivers' reactions in outpatient surgery settings. A quantitative descriptive/exploratory survey-based study involving application of a semi-structured questionnaire to 62 caregivers in two hospitals. Most caregivers (88.7%) were mothers who submitted to preoperative fasting with their children. Nervousness, anxiety and concern were the most common feelings reported by caregivers on the day of the surgery. Medical instructions regarding preoperative procedures had significant positive impacts on patient care, and on patient and caregiver stress levels. Identificar as reações dos acompanhantes de crianças submetidas à cirurgia ambulatorial. Estudo survey descritivo/ exploratório, de caráter quantitativo, realizado em dois hospitais com 62 acompanhantes que responderam um questionário semiestruturado. Constatou-se que a maioria dos acompanhantes era formada por mães (88,7%) e permaneceu em jejum junto das crianças. Todos os acompanhantes referiram sentimentos identificados como nervosismo, ansiedade e preocupação. A orientação médica aos procedimentos pré-operatórios foi de grande importância, não somente para o cuidado da criança, mas também do acompanhante, visando diminuir ao máximo o estresse vivenciado por eles.

  4. Preoperative alpha-blockade in phaeochromocytoma and paraganglioma: is it always necessary?

    PubMed

    Resection of phaeochromocytoma and paraganglioma (PPGL) is traditionally preceded by alpha-blockade to prevent complications of haemodynamic instability intraoperatively. While there is general agreement on preoperative alpha-blockade for classic PPGLs presenting with hypertension, it is less clear whether alpha-blockade is necessary in predominantly dopamine-secreting tumours, normotensive PPGLs, as well as tumours that appear to be biochemically 'silent'. Preoperative management of these 'atypical' PPGLs is challenging and the treatment approach must be individualized, carefully weighing the risk of intraoperative hypertension against the possibility of orthostatic and prolonged postoperative hypotension. Consideration of antihypertensive medication pharmacology in the light of catecholamine physiology and PPGL secretory profile will facilitate the formulation of individualized preoperative preparatory strategies. © 2016 John Wiley & Sons Ltd.

    Aspiration of stomach content is a severe complication during general anaesthesia. The DGAI (German Society for Anesthesiology and Intensive Care Medicine) guidelines recommend a fasting period for liquids of 2 h, with a maximum of 400 ml. Preoperative fasting can affect the patients' recovery after surgery due to insulin resistance and higher protein catabolism as a response to surgical stress. The aim of the study was to compare a liberal fasting regimen consisting of up to 1000 ml of liquids until 2 h before surgery with the DGAI recommendation. The prospective observational clinical study was approved by the ethics committee of the University of Leipzig. In the liberal fasting group (Glib) patients undergoing bariatric surgery were asked to drink 1000 ml of tea up to 2 h before surgery. Patients assigned to the restrictive fasting group (Gres) who were undergoing nonbariatric abdominal surgery were asked to drink no more than 400 ml of water up to 2 h preoperatively. Right after anaesthesia induction and intubation a gastric tube was placed, gastric residual volume was measured and the pH level of gastric fluid was determined. Moreover, the occurrence of aspiration was monitored. In all, 98 patients with a body mass index (BMI) of Glib 51.1 kg/m(2) and Gres 26.5 kg/m(2) were identified. The preoperative fasting period of liquids was significantly different (Glib 170 min vs. Gres 700 min, p < 0.001). There was no difference regarding the residual gastric volume (Glib 11 ml, Gres 5 ml, p = 0.355). The pH of gastric fluid was nearly similar (Glib 4.0; Gres 3.0; p = 0.864). Aspiration did not occur in any patient. There is evidence suggesting that a liberal fluid fasting regimen (1000 ml of fluid) in the preoperative period is safe in patients undergoing bariatric surgery.

    Complete surgical resection is the most effective curative treatment for lung cancer. However, many patients with lung cancer also have severe COPD which increases their risk of postoperative complications and their likelihood of being considered "inoperable." Preoperative pulmonary rehabilitation (PR) has been proposed as an intervention to decrease surgical morbidity but there is no established protocol and no randomized study has been published to date. We tested two preoperative PR interventions in patients undergoing lung cancer resection and with moderate-severe COPD in a randomized single blinded design. Outcomes were length of hospital stay and postoperative complications. The first study tested 4 weeks of guideline-based PR vs. usual care: that study proved to be very difficult to recruit as patients and providers were reluctant to delay surgery. Nine patients were randomized and no differences were found between arms. The second study tested ten preoperative PR sessions using a customized protocol with nonstandard components (exercise prescription based on self efficacy, inspiratory muscle training, and the practice of slow breathing) (n=10) vs. usual care (n=9). The PR arm had shorter length of hospital stay by 3 days (p=0.058), fewer prolonged chest tubes (11% vs. 63%, p=0.03) and fewer days needing a chest tube (8.8 vs. 4.3 days p=0.04) compared to the controlled arm. A ten-session preoperative PR intervention may improve post operative lung reexpansion evidenced by shorter chest tube times and decrease the length of hospital stay, a crude estimator of post operative morbidity and costs. Our results suggest the potential for short term preoperative pulmonary rehabilitation interventions in patients with moderate-severe COPD undergoing curative lung resection. 4 weeks of conventional preoperative PR seems non feasible.

    Purpose The purpose of this study was to assess whether preoperative chronic renal failure (CRF) affects the rates of postoperative complications and survival after liver transplantation. Methods This population-based retrospective cohort study included 2,931 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. Patients were divided into two groups, based on the presence or absence of preoperative CRF. Results The overall estimated survival rate of liver transplantation recipients (LTRs) with preoperative CRF was significantly lower than that of patients without preoperative CRF (P=0.0085). There was no significant difference between the groups in terms of duration of intensive care unit stay, total hospital stay, bacteremia, postoperative bleeding, and pneumonia during hospitalization. Long-term adverse effects, including cerebrovascular disease and coronary heart disease, were not different between patients with versus without CRF. Conclusion These findings suggest that LTRs with preoperative CRF have a higher rate of mortality. PMID:28008264

    ABSTRACT Objective: to investigate the effects of music listening, for 15 minutes, on the preoperative anxiety levels in children undergoing elective surgery in comparison with conventional pediatric surgical care. Method: randomized controlled clinical trial pilot study with 52 children in the preoperative period, aged 3 to 12 years, undergoing elective surgery and randomly allocated in the experimental group (n = 26) and control group (n = 26). Anxiety was assessed in both groups by the application of the modified Yale Preoperative Anxiety Scale and measurement of the physiological variables, upon arrival and 15 minutes after the first measurement. Results: there was a statistically significant difference in preoperative anxiety between the two groups only in relation to the physiological variable, since the respiratory rate of preschool children in the experimental group reduced in the second measurement compared to the control group (p = 0.0453). The experimental group showed a statistically significant reduction in anxiety levels after 15 minutes of music listening (p = 0.0441), specifically with regard to the behavioral domains of activity, vocalization, emotional expression and apparent awakening state. Conclusion: music listening emerges as a potential nursing intervention for relief of preoperative anxiety in children undergoing surgical procedures. RBR-7mcr59. PMID:27992027

    Preoperative preparation of the patients with adrenal cortex dysfunction is based on the careful preoperative evaluation of the type and the severity of the disturbance. The dysfunction involving adrenal glands may be: insufficiency (severe, mild, expressed) and hyperfunction (hypercorticism and/or hyperaldosteronism). If we speak about the patients with limited adrenal reserve (Addison's disease, therapeutic glucocorticoid application etc.) they need necessary corticosteroid supplementation, during preoperative preparation, as well as, during complete perioperative period. Doses needed for the substitution are adjusted according to the severity of adrenal insufficiency and according to the extent of the planned surgical procedure. Patients with Cushing's syndrome (or other form of hypercorticism), as well as, patients with Conn's syndrome (or other forms of hyperaldosteronism), do have numerous organ dysfunctions, that are significant in preoperative preparation, anesthesia and for the outcome of the surgical treatment. Common feature for both of the above syndromes is hydroelectrolyte disbalance, with hypokalemia, metabolic alkalosis and hypertension. Disturbances related to the adrenal cortex hyperfunction must be corrected preoperatively, in order to avoid complications. When we speak about hypokalemia it must be promptly corrected even before urgent/vital surgical procedure because it may cause severe intraoperative cardiac arrhythmia.

    Patients undergoing noncardiac, nonvascular surgery (NCNVS) are at risk of perioperative cardiovascular events. However, benefits of cardiology consultation (CC) in patients with known or suspected cardiac disease undergoing intermediate-risk NCNVS is unknown. The study group included 700 consecutive patients referred for CC before intermediate-risk NCNVS in a tertiary-care teaching hospital. The control group included 1200 age-matched and sex-matched consecutive patients proceeded to the intermediate-risk surgery without preoperative CC during the same period. Patients older than 18 yr who underwent an elective, NCNVS were enrolled. Requests for consultation were made either by surgeon or an attending anesthesiologist. All patients underwent a complete preoperative clinical evaluation. Of the 700 patients who were referred for CC in the study group, 530 patients (75.7%) had no additional recommendations, and 170 patients (24.3%) underwent additional preoperative tests or had a change in preoperative therapy. Only 20 (2.8%) patients' NCNVS were delayed based on the cardiologists' recommendation and 680 patients eventually had their surgeries. Major cardiovascular and noncardiovascular complication rates were similar in the study and in the control groups (12.9% vs 13.6%, p=0.273 and 25.2% vs 26%, p=0.432 respectively). Preoperative CC in patients who underwent intermediate-risk NCNVS does not affect either perioperative management or outcome of surgery. This article is protected by copyright. All rights reserved.

    The aim of this study was to examine racial differences in long-term mortality after coronary artery bypass grafting (CABG), stratified by preoperative use of inotropic agents. Black and white patients who required preoperative inotropic support prior to undergoing CABG procedures between 1992 and 2011 were compared. Mortality probabilities were computed using the Kaplan-Meier product-limit method. Hazard ratios (HR) and 95% confidence intervals (CI) were computed using a Cox regression model. A total of 15,765 patients underwent CABG, of whom 211 received preoperative inotropic agents within 48 hours of surgery. Long-term mortality differed by race (black versus white) among preoperative inotropic category (inotropes: adjusted HR = 1.6, 95% CI = 1.009–2.4; no inotropes: adjusted HR = 1.15, 95% CI = 1.08–1.2; Pinteraction < 0.0001). Our study identified an independent preoperative risk-factor for long-term mortality among blacks receiving CABG. This outcome provides information that may be useful for surgeons, primary care providers, and their patients. PMID:26154656

    In this study we evaluated whether pre-operative Western Ontario and McMaster Universities (WOMAC) osteoarthritis scores can predict satisfaction following total hip arthroplasty (THA). Prospective data for a cohort of patients undergoing THA from two large academic centres were collected, and pre-operative and one-year post-operative WOMAC scores and a 25-point satisfaction questionnaire were obtained for 446 patients. Satisfaction scores were dichotomised into either improvement or deterioration. Scatter plots and Spearman's rank correlation coefficient were used to describe the association between pre-operative WOMAC and one-year post-operative WOMAC scores and patient satisfaction. Satisfaction was compared using receiver operating characteristic (ROC) analysis against pre-operative, post-operative and δ WOMAC scores. We found no relationship between pre-operative WOMAC scores and one-year post-operative WOMAC or satisfaction scores, with Spearman's rank correlation coefficients of 0.16 and -0.05, respectively. The ROC analysis showed areas under the curve (AUC) of 0.54 (pre-operative WOMAC), 0.67 (post-operative WOMAC) and 0.43 (δ WOMAC), respectively, for an improvement in satisfaction. We conclude that the pre-operative WOMAC score does not predict the post-operative WOMAC score or patient satisfaction after THA, and that WOMAC scores can therefore not be used to prioritise patient care.

    Stable hemodynamics, normocapnia, and adequate pain relief are considered important factors in the reduction of neurological complications in pediatric patients undergoing encephaloduroarteriomyosynangiosis (EDAMS) operations for the treatment of moyamoya disease. A preoperative skull block may reduce hemodynamic fluctuations and hypo- or hyperventilation due to emergence delirium or oversedation and provide adequate pain relief, thereby reducing postoperative morbidity. Pediatric patients (age 3-13 years) undergoing EDAMS surgery for moyamoya disease were randomly divided into a nerve block (NB) group (18 cases) or control group (21 cases). The treatment group patients received a preoperative NB (0.25% 5-8 ml bupivacaine mixed with 20-40 mg methylprednisolone) targeting the supraorbital, supratrochlear, auriculotemporal, and posterior auricular nerves. Patients in the control group did not receive NB. General anesthesia with sevoflurane was induced in both groups. In the NB group, stable hemodynamic parameters were obtained with a lower sevoflurane concentration than in the control group. For delirious awakening, the odds ratio in the control group was 4.9 compared with the NB group. Pain and analgesic requirement were higher in the control patients than in the NB-treated patients during the postanesthesia care unit stay. However, the arterial CO(2) tension in the postanesthesia care unit did not differ between the 2 groups. The odds ratio in the control group for the rate of morbidity (cerebral infarction and reversible ischemic neurological deficits) during the first 24 hours following the operation was 3.2 compared with the NB group. The use of skull block during EDAMS surgery provided easy hemodynamic control, calm awakening, and better pain relief and may be related to the reduced postoperative morbidity.

    Fifty consecutive patients underwent minor elective gynecologic surgery. Most of them were from the low socioeconomic class. Twenty-five patients had their pubic, vulval and perineal hair shaved as part of the preoperative preparation. All patients underwent the same routine perineal, vulval and vaginal swabbing in the operating room. All patients were then examined for postoperative complications. Only two women (who were shaved) complained of mild lower abdominal pain 48 hours after operation, but neither had any clinical evidence of genital or urinary infection. Their symptoms disappeared with the use of analgesics. Even in developing countries where patients with poor personal hygiene are common, preoperative vulval, pubic and perineal hair shaving prior to minor gynecologic surgery is unnecessary. We suggest that this procedure should be discontinued.

    Purpose: To assess the technical success rate, complications, and effect on intraoperative blood loss of preoperative transarterial embolization of cervical spine tumors. Methods: A retrospective analysis was performed on 38 patients with tumors of the cervical spine; 69 vertebrae were affected. Polyvinyl alcohol particles, coils, gelfoam particles, either alone or in combination, were used for preoperative tumor embolization. After embolization a total of 57 corporectomies with titanium basket implantation were performed. Results: In 36 of 38 patients, complete (n= 27) or partial (n= 9) embolization was achieved. In 23 patients one vertebral artery was completely occluded by coil placement, and in one patient the ipsilateral internal and external carotid arteries were occluded in addition. No neurological complications could be directly related to the embolization, but two postoperative brain stem infarctions occurred. The mean intraoperative blood loss was 2.4 L. Conclusion: Transarterial embolization of cervical spine tumors is a safe and effective procedure to facilitate extensive surgery.

    Preoperative lung function tests are useful to evaluate the preoperative pulmonary condition and to detect a high risk of postoperative pulmonary complications. However, maximum expiratory effort by patients is necessary to determine lung function using spirometry and flow-volume curve measurements. When patients are not able to expire completely during the measurement, incorrect data regarding their respiratory system is obtained. On the other hand, respiratory system impedance using an impulse oscillatory system (IOS) can evaluate total airway resistance (R5), large airway resistance (R20), small airway resistance (R5-20) and reactance (X5) under breathing at rest within a few minutes. There are few reports that indicate the standard values for IOS. In addition, the effects of age on IOS value are not clear. In this study preoperative lung functions using IOS were studied to examine the standard value and effect of aging. Subjects were 420 patients aged from 20 to 89 years with normal pulmonary function (%VC > or = 80%, %FEV(1.0) > or = 70%), and scheduled for an elective surgery. Lung function measurements such as IOS, spirometry, maximum expiratory flow-volume curve and single N2 washout were done preoperatively. Subjects were divided into seven groups in decades from 20 to 80. Although there was no statistical change in R5, R20, R5-R20, Z5 and X5 in the decades from 20 to 60, there were statistically significant changes during the 70s and 80s. There were significant differences in IOS parameters between the adult group and the aged group. Changes due to aging were stronger on V25/Ht than those of IOS. This study indicates that there are differences between V25/Ht and IOS values because of the difference in breathing conditions during measurements.

    Purpose We compared the frequency and sequence of breast imaging and biopsy use for the diagnostic and preoperative workup of breast cancer according to breast MRI use among older women. Methods Using SEER-Medicare data from 2004–2010, we identified women with and without breast MRI as part of their diagnostic and preoperative breast cancer workup and measured the number and sequence of breast imaging and biopsy events per woman. Results 10,766 (20%) women had an MRI in the diagnostic/preoperative period, 32,178 (60%) had mammogram and US, and 10,669 (20%) had mammography alone. MRI use increased across study years, tripling from 2005 to 2009 (9% to 29%). Women with MRI had higher rates of breast imaging and biopsy compared to those with mammogram and US or those with mammography alone (5.8 v 4.1 v 2.8; respectively). There were 4,254 unique sequences of breast events; the dominant patterns for women with MRI were an MRI occurring at the end of the care pathway. Among women receiving an MRI post-diagnosis, 26% had a subsequent biopsy compared to 51% receiving a subsequent biopsy in the sub-group without MRI. Conclusions Older women who receive breast MRI undergo additional breast imaging and biopsy events. There is much variability in the diagnostic/preoperative work-up in older women, demonstrating the opportunity to increase standardization to optimize care for all women. PMID:27111752

    Delirium is an acute deterioration of brain function characterized by fluctuating consciousness and an inability to maintain attention. Use of statins has been shown to decrease morbidity and mortality after major surgical procedures. The objective of this study was to determine an association between preoperative administration of statins and postoperative delirium in a large prospective cohort of patients undergoing cardiac surgery with cardiopulmonary bypass. After Institutional Review Board approval, data were prospectively collected on consecutive patients undergoing cardiac surgery with cardiopulmonary bypass from April 2005 to June 2006 in an academic hospital. All patients were screened for delirium during their hospitalization using the Confusion Assessment Method in the intensive care unit. Multivariable logistic regression analysis was used to identify independent perioperative predictors of delirium after cardiac surgery. Statins were tested for a potential protective effect. Of the 1,059 patients analyzed, 122 patients (11.5%) had delirium at any time during their cardiovascular intensive care unit stay. Administration of statins had a protective effect, reducing the odds of delirium by 46%. Independent predictors of postoperative delirium included older age, preoperative depression, preoperative renal dysfunction, complex cardiac surgery, perioperative intraaortic balloon pump support, and massive blood transfusion. The model was reliable (Hosmer-Lemeshow test, P = 0.3) and discriminative (area under receiver operating characteristic curve = 0.77). Preoperative administration of statins is associated with the reduced risk of postoperative delirium after cardiac surgery with cardiopulmonary bypass.

    Carotid body tumors (CBTs) are relatively frequent lesions encountered at high altitudes, such in as the Andean Mountains. A correct preoperative diagnosis is essential for surgical planning and performance. For this reason, we have reviewed the evolution of our experience in the imaging diagnosis of these tumors. Between 1980 and June 2008, 160 CBTs were diagnosed. A total of 138 tumors were operated on, 4 are waiting for surgery, and 18 were not operated on because of age, medical conditions, or patient refusal. We have reviewed retrospectively the modalities of imaging diagnosis in our patients who underwent operation. Among the 138 tumors operated on, a correct preoperative diagnosis was done in 127 cases (92%). The preoperative diagnosis of the remaining 11 patients was unspecified benign tumor for 6 patients and neck lymph node for 5 patients. The imaging methods performed by different radiologists were conventional ultrasound, color Doppler ultrasound, carotid conventional angiography (CA), axial tomography, magnetic resonance and magnetic resonance angiography, and computed tomographic angiography (CTA). Most patients had more than one image study. Review of radiologist reports revealed a correct diagnosis in all carotid CA, magnetic resonance studies, and CTA. Additionally, CTA appeared to be a valuable method to predict the Shamblin group. Clinical suspicion and current image techniques permit a correct diagnosis in practically all cases of CBT.

    The value of routine preoperative testing before most surgical procedures is widely considered to be low. To improve the quality of preoperative care and reduce waste, 2 professional societies released guidance on use of routine preoperative testing in 2002, but researchers and policymakers remain concerned about the health and cost burden of low-value care in the preoperative setting. To examine the long-term national effect of the 2002 professional guidance from the American College of Cardiology/American Heart Association and the American Society of Anesthesiologists on physicians' use of routine preoperative testing. Retrospective analysis of nationally representative data from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey to examine adults in the United States who were evaluated during preoperative visits from January 1, 1997, through December 31, 2010. A quasiexperimental, difference-in-difference (DID) approach evaluated whether the publication of professional guidance in 2002 was associated with changes in preoperative testing patterns, adjusting for temporal trends in routine testing, as captured by testing patterns in general medical examinations. Physician orders for outpatient plain radiography, hematocrit, urinalysis, electrocardiogram, and cardiac stress testing. During the 14-year period, the average annual number of preoperative visits in the United States increased from 6.8 million in 1997-1999 to 9.8 million in 2002-2004 and 14.3 million in 2008-2010. After accounting for temporal trends in routine testing, we found no statistically significant overall changes in the use of plain radiography (11.3% in 1997-2002 to 9.9% in 2003-2010; DID, -1.0 per 100 visits; 95% CI, -4.1 to 2.2), hematocrit (9.4% in 1997-2002 to 4.1% in 2003-2010; DID, 1.2 per 100 visits; 95% CI, -2.2 to 4.7), urinalysis (12.2% in 1997-2002 to 8.9% in 2003-2010; DID, 2.7 per 100 visits; 95% CI, -1.7 to 7.1), or cardiac

    Objectives A PSA velocity (PSAV) >0.35 ng/ml/year approximately 10–15 years prior to diagnosis is associated with a greater risk of lethal prostate cancer. Some have recommended that a PSAV >0.35 ng/ml/year should prompt a prostate biopsy in men with a low serum PSA (<4 ng/ml) and benign DRE. However, less is known about the utility of this PSAV cutpoint for the prediction of treatment outcomes among men undergoing radical prostatectomy (RP). Methods Between 1992 and 2007, 339 men underwent RP at our institution with a preoperative PSA <4 ng/ml, benign DRE, and multiple preoperative PSA measurements. PSAV was calculated by linear regression analysis using all PSA values within 18 months prior to diagnosis. Kaplan–Meier survival analysis was performed, and biochemical progression rates were compared between PSAV strata using the log-rank test. Results The preoperative PSAV was >0.35 ng/ml/year in 124 (36.6%) of 339 men. Although there were no significant differences in clinicopathological characteristics based upon PSAV, men with a PSAV >0.35 ng/ml/year were significantly more likely to experience biochemical progression after RP at a median follow-up of 4 years (P = 0.022). Conclusions In this low-risk population with a preoperative PSA <4 ng/ml and benign DRE, approximately 1/3 had a preoperative PSAV >0.35 ng/ml/year. Physicians should carefully monitor men with a preoperative PSA >0.35 ng/ml/year as they are at increased risk of biochemical progression following RP. PMID:21153643

    Acute kidney injury (AKI) after cardiac surgery is a common and serious complication. Although lower than normal serum bicarbonate levels are known to be associated with consecutive renal function deterioration in patients with chronic kidney injury, it is not well-known whether preoperative low serum bicarbonate levels are associated with the development of AKI in patients who undergo cardiac surgery. Therefore, the clinical implication of preoperative serum bicarbonate levels on AKI occurrence after cardiac surgery was investigated. Patients who underwent coronary artery bypass or valve surgery at Yonsei University Health System from January 2013 to December 2014 were enrolled. The patients were divided into 3 groups based on preoperative serum bicarbonate levels, which represented group 1 (below normal levels) <23 mEq/L; group 2 (normal levels) 23 to 24 mEq/L; and group 3 (elevated levels) >24 mEq/L. The primary outcome was the predicated incidence of AKI 48 hours after cardiac surgery. AKI was defined according to Acute Kidney Injury Network criteria. Among 875 patients, 228 (26.1%) developed AKI within 48 hours after cardiac surgery. The incidence of AKI was higher in group 1 (40.9%) than in group 2 (26.5%) and group 3 (19.5%) (P < 0.001). In addition, the duration of postoperative stay in a hospital intensive care unit (ICU) was longer for AKI patients and for those in the low-preoperative-serum-bicarbonate-level groups. A multivariate logistic regression analysis showed that low preoperative serum bicarbonate levels were significantly associated with AKI even after adjustment for age, sex, hypertension, diabetes mellitus, operation type, preoperative hemoglobin, and estimated glomerular filtration rate. In conclusion, low serum bicarbonate levels were associated with higher incidence of AKI and prolonged ICU stay. Further studies are needed to clarify whether strict correction of bicarbonate levels close to normal limits may have a protective

    The preoperative education, which occurs in preoperative patient consultations, is an important part of the surgical nurse's profession. These consultations may be the building blocks of a partnership that facilitates communication between patient and nurse. The aim of the study was to describe topics and structure and documentation in preoperative nursing consultations with patients undergoing surgery for colorectal cancer. The study was based on analysis of consultations between seven patients and nurses at a Swedish university hospital. The preplanned preoperative consultations were audio-recorded and transcribed verbatim. The structure of the consultations was described in terms of phases and the text was analysed according to a manifest content analysis RESULTS: The consultations were structured on an agenda that was used variously and communicating different topics in an equally varied manner. Seven main topics were found: Health status, Preparation before surgery, Discovery, Tumour, Operation, Symptoms and Recovery after surgery. The topic structure disclosed a high number of subtopics. The main topics 'Discovery', 'Tumour' and 'Symptoms' were only raised by patients and occupied only 11% of the discursive space. Documentation was sparse and included mainly task-oriented procedures rather than patients' worries and concerns. There was no clear structure regarding preoperative consultation purpose and content. Using closed questions instead of open is a hindrance of developing a dialogue and thus patient participation. Preoperative consultation practice needs to be strengthened to include explicit communication of the consultations' purpose and agenda, with nurses actively discussing and responding to patients' concerns and sensitive issues. The results of the study facilitate the development of methods and structure to support person-centred communication where the patient is given space to get help with the difficult issues he/she may have when undergoing

    The advent of managed care, reduction of costs, and advances in medical technology place increasing demands on anesthesiologists. Preoperative anxiety may go unnoticed in an environment that stresses increased productivity. The present study compares different methods for measuring preoperative anxiety, identifies certain patient characteristics that predispose to high anxiety, and describes the quantity and quality of anxiety that patients experience preoperatively. Seven hundred thirty-four patients participated in the study. We assessed aspects of anxiety by means of visual analog scales (VAS) and the State Anxiety Score of the Spielberger State-Trait Anxiety Inventory (STAI). The mean STAI anxiety score was 39 +/- 1 (n = 486) and the mean VAS for fear of anesthesia was 29 +/- 1 (n = 539). Patients feared surgery significantly more than anesthesia (P < 0.001). The VAS measuring fear of anesthesia correlated well with the STAI score (r = 0.55; P < 0.01). Young patients, female patients, and patients with no previous anesthetic experience or a previous negative anesthetic experience had higher anxiety scores. Patients worried most about the waiting period preceding surgery and were least concerned about possible awareness intraoperatively. Factor analysis of various anxiety items showed three distinct dimensions of fear: 1) the fear of the unknown 2) the fear of feeling ill, and 3) the fear for one's life. Among these dimensions, fear of the unknown correlated highest with the anxiety measuring techniques STAI and VAS. The simple VAS proved to be a useful and valid measure of preoperative anxiety. The study of qualitative aspects of anxiety reveals three distinct dimensions of preoperative fear: fear of the unknown, fear of feeling ill, and fear for one's life. Groups of patients with a higher degree of preoperative anxiety and their specific anesthetic concerns can be identified using the visual analog scale.

  6. Preoperative intra-aortic balloon pumping in high-risk cardiac surgery patients.

    PubMed

    Moon, Chooza

    2012-01-01

    Intra-aortic balloon pumping increases myocardial oxygen supply and decreases myocardial oxygen demand by inflation and deflation of the balloon. This leads to increased perfusion of the coronary arteries during diastole. This technology has been used for critically ill cardiac patients for more than 30 years. The literature suggests that preoperative use of an intra-aortic balloon pump can be effective in high-risk coronary artery bypass grafting patients. Preoperative benefits of this technology may yield positive outcomes in terms of hemodynamic effect, decreased length of stay in both the intensive care unit and the hospital, and the reduction of complications. However, the intra-aortic balloon pump must be used with a profound understanding of proper mechanism and function, monitoring, and observation for potential complications. This requires excellent critical care nursing management.

    The potential adverse effect of preoperative opioid use on outcomes after reverse shoulder arthroplasty (RSA) has not been investigated. The purpose of this study was to evaluate outcomes after RSA in patients with a history of preoperative opioid use and compare them with a control group without a history of preoperative opioid use. Sixty-eight RSAs performed for rotator cuff tear arthropathy (CTA) with a minimum of 2 years of follow-up were identified in a prospective shoulder arthroplasty registry. Thirty-two patients with a history of preoperative opioid use for shoulder pain were compared with a control group of 36 patients who did not use opioids preoperatively. Shoulder function scores and range of motion measurements were assessed preoperatively and at the final follow-up. No differences were noted between the 2 groups in age, gender, duration of follow-up, depression, smoking, chronic back pain, diabetes, heart disease, or body mass index. Preoperative opioid use was associated with significantly lower preoperative shoulder function scores. Both groups significantly improved on all shoulder function scores and for range of motion measurements from the preoperative to the final follow-up assessment; however, the nonopioid group had significantly better outcomes. The magnitude of change between the groups from preoperatively to the final follow-up was nearly identical. Improvements can be expected in patients with a history of preoperative opioid use; however, patients with preoperative opioid use have a lower preoperative baseline and should not expect to reach the same peak outcome scores after RSA as patients without a history of preoperative opioid use.

    While the association between scoliosis and cardiac and respiratory function impairments has been well characterized in clinical practice and research, the potential effect of scoliosis on urinary tract structure and renal function has received little attention. Therefore, the purpose of this study was to evaluate the preoperative clinical characteristics of urinary tract structure and renal function in pediatric patients with idiopathic scoliosis, using a combination of blood tests, urinalysis, and imaging. Preoperative measures of urinary tract structure and renal function were obtained for 16 patients, 13-17 years old, scheduled for corrective surgery for idiopathic scoliosis. Preoperative assessment included blood test and urinalysis, combined with structural imaging on ultrasound (US), magnetic resonance imaging (MRI), magnetic resonance urography (MRU), and radioisotope tracing (RI), using technetium-99 m mercaptoacetyltriglycine ((99m) Tc-MAG3). Differences in blood and urine tests between patients with and without urinary tract obstruction (UTO) were evaluated for significance using Mann-Whitney U test. For all 16 patients, blood tests and MRU were within normal limits. Dilatation of the renal pelvis was identified on US in eight patients (50.0%). UTO was identified on RI in six patients (37.5%). UTO was associated with elevated β2-microglobulin concentration. Urinary β2-microglobulin concentration >0.7 μg/mg Cr differentiated patients with UTO from those without UTO, with a sensitivity of 100% and specificity of 70%. β2-Microglobulin concentration may be a useful marker to screen for asymptomatic UTO in patients with idiopathic scoliosis. © 2016 Japan Pediatric Society.

    Diabetes mellitus is an increasingly common disease that affects people of all ages, resulting in significant morbidity and mortality. Diabetic patients require perioperative care more frequently than their nondiabetic counterparts. The major risk factors for diabetics undergoing surgery are the associated end-organ diseases: cardiovascular disease, autonomic neuropathy, joint collagen tissue, and immune deficiency. Physicians need to pay extra attention to preoperative and preprocedure evaluation and treatment of these diseases to ensure optimal perioperative management.

    Background This study aimed to evaluate the impact of preoperative pulmonary rehabilitation in lung cancer patients undergoing pulmonary resection surgery with marginal lung function. Methods Short-term outcomes of 42 patients with forced expiratory volume in 1 s < 1.6 L who underwent lung resection between 01/2006 and 12/2010 were reviewed retrospectively. They were divided into group A (no preoperative pulmonary rehabilitation) and group B (receiving pulmonary rehabilitation). In group B, a second set of pulmonary function tests was obtained. Results There were no significant differences in terms of sex, age, race, pathologic stage, operative procedure, or smoking years. Mean forced expiratory volume in 1 s and diffusing capacity for carbon monoxide in group A was 1.40 ± 0.22 L and 10.28 ± 2.64 g∙dL(-1) vs. 1.39 ± 0.13 L and 10.75 ± 2.08 g∙dL(-1) in group B. Group B showed significant improvement in forced expiratory volume in 1 s from 1.39 ± 0.13 to 1.55 ± 0.06 L ( p = 0.02). Mean intensive care unit stay was 6 ± 5 days in group A vs. 9 ± 9 days in group B ( p = 0.22). Mean hospital stay was 10 ± 4 days in group A vs. 14 ± 9 days in group B ( p = 0.31). There was no significant difference in morbidity or mortality between groups. Conclusion Preoperative pulmonary rehabilitation can significantly improve forced expiratory volume in 1 s in some marginal patients undergoing lung cancer resection. However, it does not improve length of stay, morbidity, or mortality.

    Prior to elective surgery it is essential to know in advance the patient’s clinical condition. The aim of this study was to compare the preoperative evaluation (POE) through questionnaire responses with preanesthetic evaluation by the anesthesiologist. Prior to their preoperative evaluation, patients answered a questionnaire with information regarding age, weight, height, scheduled surgery, past medical and surgical history, allergies, medications and doses used, social history (illicit drugs, alcohol, smoking), functional capacity and exercise tolerance. Preoperative evaluation was performed by an anesthesiologist who had no access to the questionnaire data or knowledge about the research. The questionnaire data were compared with the preoperative evaluation by two independent investigators, in order to answer the questions: 1) Was the questionnaire evaluation effective - could the patient undergo surgery without the need for face-to-face consultation? 2) Has been there any relevant information - ability to change the anesthetic approach - not assessed by the questionnaire, but assessed by the face-to-face consultation? 3) Has been there any information added by the health questionnaire that was missed by face-to-face consultation? For statistical analysis, the paired Student’s t-test was used for parametric data and chi-square test for categorical data, with p < 0.05 considered significant. Of the 269 eligible patients there was one refusal, and four agreed to participate but did not complete the questionnaire, in addition to 52 losses, totaling 212 participants. Questionnaire data added to the consultation in 109 cases (51.4%). The screening questionnaire alone was effective for 144 patients (67.93%), with no need for consultation.

    Synopsis This article provides an overview of the neuroimaging literature focused on pre-operative prediction of meningioma consistency. A validated, non-invasive neuroimaging method to predict tumor consistency can provide valuable information regarding neurosurgical planning and patient counseling. Most of the neuroimaging literature indicates conventional MRI using T2-weighted imaging (T2WI) may be helpful to predict meningioma consistency, however, further rigorous validation is necessary. Much less is known about advanced MRI techniques such as diffusion MRI, MR elastography (MRE) and MR spectroscopy (MRS). Of these methods, MRE and DTI appear particularly promising. PMID:27012379

    A simple method of preoperative marking for reduction mammaplasty is described. This method may be used in macromastias when the technique chosen implies a postoperative scar with the shape of an inverted T. The marking sequence follows standard steps, but the drawing is always different because it is a consequence of the shape of the breast. This marking method reduces the chance of making mistakes due to excessive personal evaluations or to the use of standard drawing patterns that may be not suitable for all breast shapes.

    To determine selection and delivery of preoperative verbal information deemed important by nurses to relay to patients immediately prior to day surgery. Elective day-case surgery is expanding, patient turnover is high and nurse-patient contact limited. In the brief time-frame available, nurses must select and precisely deliver information to patients, provide answers to questions and gain compliance to ensure a sustained, co-ordinated patient throughput. Concise information selection is therefore necessary especially given continued day surgery expansion. Electronic questionnaire. A survey investigating nurses' choice of patient information prior to surgery was distributed throughout the UK via email addresses listed on the British Association of Day Surgery member's website (January 2015-April 2015). Participants were requested to undertake the survey within 2-3 weeks, with 137 participants completing the survey giving a 44% response rate. Verbal information deemed most important by nurses preoperatively was checking fasting time, information about procedure/operation, checking medication, ensuring presence of medical records/test results and concluding medical investigations checks. To a lesser extent was theatre environment information, procedure/operation start time and possible time to discharge. Significant differences were established between perceived importance of information and information delivery concerning the procedure/operation and anaesthesia details. Nurses working with competing demands and frequent interruptions, prioritised patient safety information. Although providing technical details during time-limited encounters, efforts were made to individualise provision. A more formal plan of verbal information provision could help ease nurses' cognitive workload and enhance patient satisfaction. This study provides evidence that verbal information provided immediately prior to day surgery may vary with experience. Nurse educators and managers may

    In other surgical fields, preoperative level of participation in activities of daily living (ADLs) has been found to be important in predicting outcomes. To date, postoperative ADL measurements have only been used to characterize outcomes following lumbar discectomy. The present study's goal was to determine if patients' preoperative ability to perform ADLs correlates with their postoperative outcomes after lumbar discectomy at 3 months and 1 year. This retrospective study was performed using prospectively collected data from patients prospectively enrolled in a randomized clinical trial. All patients were 18 years or older, spoke English, had not previously had lumbar surgery, and underwent discectomy for a single-level lumbar disc herniation. Oswestry disability index (ODI) and visual analogue scale (VAS) back and leg pain scores were collected preoperatively and at 3 months and 1 year postoperatively. Simple linear regression analysis was performed to detect any significant correlations between three preoperative ODI domain values and postoperative scores. Additionally, regression analysis was used to determine the correlation between the preoperative ODI domains and percentage of good and poor outcomes, where an improvement of at least 18.8 points for ODI and at least 2 points for VAS constituted a good outcome. 90 subjects satisfied inclusion criteria (average age 42, 53 males, 37 females). Patients' ability to take care of themselves and to stand preoperatively were correlated with improvement in ODI postoperatively, with worse ability corresponding to more improvement (p<0.001 for both). Only personal care scores correlated with good improvement in leg pain. No significant correlations were found with back pain. When evaluating patients by dichotomized outcome (good or poor), only preoperative ability to participate in personal care was consistently significantly correlated to a good outcome. This is the first study to suggest that lower preoperative ability

    Objective To determine whether preoperative biliary instrumentation and preoperative biliary drainage are associated with increased morbidity and mortality rates after pancreaticoduodenectomy. Summary Background Data Pancreaticoduodenectomy is accompanied by a considerable rate of postoperative complications and potential death. Controversy exists regarding the impact of preoperative biliary instrumentation and preoperative biliary drainage on morbidity and mortality rates after pancreaticoduodenectomy. Methods Two hundred forty consecutive cases of pancreaticoduodenectomy performed between January 1994 and January 1997 were analyzed. Multiple preoperative, intraoperative, and postoperative variables were examined. Pearson chi square analysis or Fisher’s exact test, when appropriate, was used for univariate comparison of all variables. Logistic regression was used for multivariate analysis. Results One hundred seventy-five patients (73%) underwent preoperative biliary instrumentation (endoscopic, percutaneous, or surgical instrumentation). One hundred twenty-six patients (53%) underwent preoperative biliary drainage (endoscopic stents, percutaneous drains/stents, or surgical drainage). The overall postoperative morbidity rate after pancreaticoduodenectomy was 48% (114/240). Infectious complications occurred in 34% (81/240) of patients. Intraabdominal abscess occurred in 14% (33/240) of patients. The postoperative mortality rate was 5% (12/240). Preoperative biliary drainage was determined to be the only statistically significant variable associated with complications (p = 0.025), infectious complications (p = 0.014), intraabdominal abscess (p = 0.022), and postoperative death (p = 0.037). Preoperative biliary instrumentation alone was not associated with complications, infectious complications, intraabdominal abscess, or postoperative death. Conclusions Preoperative biliary drainage, but not preoperative biliary instrumentation alone, is associated with increased

    The preoperative detection of accessory spleen (AS) is still a very important and serious problem. The aim of the study was to assess the reasons for failure and the long-term results of laparoscopic splenectomy (LS) in patients with idiopathic thrombocytopenic purpura (ITP). Fifty-eight ITP patients underwent LS between June 1998 and December 2002. There were 42 women and 16 men. Preoperatively, we performed computed tomography (CT) and sonography to evaluate the size of the spleen and possibly to recognize the presence of the accessory spleens, which were found preoperatively in three cases. Intraoperatively, ASs were found in the course of laparoscopy in six cases overall, three preoperatively false negative. During follow-up (median time 31 months), in three patients the low platelet count was recognized, respectively after 5 months and 1.5 and 1.8 years. In all those cases scintigraphy was performed and in one case the residual accessory spleen, missed both in preoperative examination and during laparoscopy, was revealed. In two other patients, in spite of thrombocytopenia, no residual spleens were found. We conclude that the problem of accessory spleens can be managed by careful videoscopic examination of the abdominal cavity during splenectomy, while the use of preoperative imaging techniques in detection of accessory spleens is still limited by the insufficient sensitivity of the examination.

    During the last decades lung cancer is the leading cause of death worldwide for both sexes. Even though cigarette smoking has been proved to be the main causative factor, many other agents (e.g., occupational exposure to asbestos or heavy metals, indoor exposure to radon gas radiation, particulate air pollution) have been associated with its development. Recently screening programs proved to reduce mortality among heavy-smokers although establishment of such strategies in everyday clinical practice is much more difficult and unknown if it is cost effective compared to other neoplasms (e.g., breast or prostate cancer). Adding severe comorbidities (coronary heart disease, COPD) to the above reasons as cigarette smoking is a common causative factor, we could explain the low surgical resection rates (approximately 20-30%) for lung cancer patients. Three clinical guidelines reports of different associations have been published (American College of Chest Physisians, British Thoracic Society and European Respiratory Society/European Society of Thoracic Surgery) providing detailed algorithms for preoperative assessment. In the current mini review, we will comment on the preoperative evaluation of lung cancer patients.

    1 Efficacy of and tolerance to brotizolam when used as a preoperative hypnotic were studied in two double-blind, randomised parallel group studies. 2 Brotizolam (0.25 and 0.50 mg) was superior to placebo. Efficacy was assessed as good-to-satisfactory in 73.0% of patients with 0.25 mg and in 88.0% with 0.5 mg. A similar assessment was reached in 40.0% of patients with placebo. Brotizolam 0.5 mg was superior to 0.25 mg, and with the higher dose subjective assessments of anxiety were reduced. 3 Efficacy of tolerance to 0.5 mg brotizolam and 2.0 mg flunitrazepam were compared, and both drugs were found to be effective and well tolerated. Brotizolam maintained sleep throughout the night more effectively than flunitrazepam. 4 A dose range of 0.25-0.5 mg brotizolam is recommended as a pre-operative hypnotic. PMID:6362702

  4. Preoperative Preparation and Anesthesia for Trabeculectomy

    2016-01-01

    ABSTRACT Preoperative preparation should improve the likelihood of successful trabeculectomy surgery. The team can reconsider the appropriateness of the proposed surgery, and steps can be taken to maximize the chance of a good outcome. For example, adjustments to anti-hypertensive or anti-coagulant medications may be made, and topical ocular medications adjusted. Choice of anesthesia technique is of particular relevance to the trabeculectomy patient. Some anesthesia techniques are more likely to have serious complications, and glaucoma patients may be at higher risk of some sight-threatening complications, because the optic nerve is already damaged and vulnerable. Posterior placement of local anesthesia (retrobulbar, peribulbar, posterior sub-Tenon’s techniques) could potentially damage the optic nerve, and thereby cause “wipe-out” of vision. Anesthesia technique may influence the likelihood of vitreous bulge and surgical difficulty. Regarding long-term control of intraocular pressure, there is no good evidence to indicate that any particular anesthesia technique is better than another. There is little high-quality evidence on this topic. The author’s preferred technique for trabeculectomy is subconjunctival-intracameral anesthesia without sedation. How to cite this article: Eke T.

    Chow, Cheryl H T; Van Lieshout, Ryan J; Schmidt, Louis A; Buckley, Norman

    To examine the feasibility, acceptability, and effects of a novel tablet-based application, Story-Telling Medicine (STM), in reducing children's preoperative anxiety. Children (N = 100) aged 7 to 13 years who were undergoing outpatient surgery were recruited from a local children's hospital. This study comprised 3 waves: Waves 1 (n = 30) and 2 (n = 30) examined feasibility, and Wave 3 (n = 40) examined the acceptability of STM and compared its effect on preoperative anxiety to Usual Care (UC). In Wave 3, children were randomly allocated to receive STM+UC or UC. A change in preoperative anxiety was measured using the Children's Perioperative Multidimensional Anxiety Scale (CPMAS) 7 to 14 days before surgery (T1), on the day of surgery (T2), and 1 month postoperatively (T3). Wave 1 demonstrated the feasibility of participant recruitment and data collection procedures but identified challenges with attrition at T2 and T3. Wave 2 piloted a modified protocol that addressed attrition and increased the feasibility of follow-up. In Wave 3, children in the STM+UC demonstrated greater reductions in CPMAS compared with the UC group (ΔM = 119.90, SE = 46.36, t(27) = 2.59, p = .015; 95% confidence interval = 24.78-215.02). This pilot study provides preliminary evidence that STM is a feasible and acceptable intervention for reducing children's preoperative anxiety in a busy pediatric operative setting and supports the investigation of a full-scale randomized controlled trial.

    Preoperative anxiety is a significant problem worldwide that may affect patients' surgical outcome. By using a simple and reliable tool such as the Amsterdam Preoperative Anxiety and Information Scale (APAIS), anaesthesiologists would be able to assess preoperative anxiety adequately and accurately. The purpose of this study was to develop and validate the Malay version of APAIS (Malay-APAIS), and assess the factors associated with higher anxiety scores. The authors performed forward and backward translation of APAIS into Malay and then tested on 200 patients in the anaesthetic clinic of University Malaya Medical Centre. Psychometric analysis was performed with factor analysis, internal consistency and correlation with Spielberger's State-Trait Anxiety Inventory (STAI-state). A good correlation was shown with STAI-state (r = 0.59). Anxiety and need for information both emerged with high internal consistency (Cronbach's alpha 0.93 and 0.90 respectively). Female gender, surgery with a higher risk and need for information were found to be associated with higher anxiety scores. On the other hand, previous experience with surgery had lower need for information. The Malay-APAIS is a valid and reliable tool for the assessment of patients' preoperative anxiety and their need for information. By understanding and measuring patient's concerns objectively, the perioperative management will improve to a much higher standard of care.

    Equity in health care has become a focal point of debate. However, the disparity between insurance payer types in total joint arthroplasty is poorly defined. The authors identified 1312 consecutive patients who underwent elective primary total hip or knee arthroplasty with available preoperative Short Form 36 and Western Ontario and McMaster University Osteoarthritis Index surveys and stratified them into groups based on insurance type (Iowa Care [a state-run insurance program for patients who are indigent], Medicare, Medicaid, or private insurance) to compare demographics, access to care, and functional data. Significance was a P value less than .05 after a Turkey-Kramer adjustment for multiple comparisons. A multivariate analysis identified independent predictors of Short Form 36 and Western Ontario and McMaster University Osteoarthritis Index preoperative functional status. Few differences existed between patients with Iowa Care and Medicaid, but both groups had significantly lower Short Form 36 and Western Ontario and McMaster University Osteoarthritis Index scores across every category compared with patients with Medicare or private insurance (P<.05 for each comparison). In addition, patients with Iowa Care and Medicaid had a higher incidence of current smoking and higher mean body mass index and traveled an average of 29 to 30 miles farther for access to care (P<.05 for each comparison). Payer type was an independent predictor of preoperative Short Form 36 and Western Ontario and McMaster University Osteoarthritis Index functional scores in the multivariate analysis (P<.02). Significant differences exist between payer types in total joint arthroplasty. Further research is necessary to better inform health policy decisions. Copyright 2012, SLACK Incorporated.

    Preoperative anxiety is a major problem in patients with brain tumors and is of high clinical relevance. However, to date no instruments have been validated for the assessment of preoperative anxiety for this patient group. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) has shown promising results for the assessment of preoperative anxiety. The aim of this study was to determine its psychometric properties and the optimal cutoff score for patients with intracranial tumors to make it applicable in the neurosurgical setting. The sample totaled 180 neurosurgical patients with intracranial tumors. Patients were administered the APAIS along with the Hospital Anxiety and Depression Scale as the gold standard against which the APAIS was compared. Patients scoring 11 or above in the anxiety subscale of the Hospital Anxiety and Depression Scale were defined as clinical cases having anxiety. The psychometric properties of the APAIS were evaluated for a postulated 2-factor structure, Cronbach α, and correlations. The postulated 2-factor structure could not be replicated. Instead, we found a 3-factor solution (anxiety about the operation, anxiety about the anesthesia, information requirement). The area under the receiver operating characteristics curve ranged from ≥0.65 to ≥0.77. Optimal cutoff scores were calculated. The cutoff score for the anxiety scale was ≥10 for the whole sample and men only, and was ≥11 for women only. Analysis of the psychometric properties yielded satisfactory results (eg. Cronbach α for the anxiety scale >0.84). Despite its brevity, the APAIS is valid and recommendable for the assessment of preoperative anxiety in patients with intracranial tumors. As this is the first validation study focusing on patients with severe diseases and major surgeries, we recommend the application of our cutoff scores also for patients similar to our study population with regard to disease and surgery severity.

    The preferred treatment for lung cancer is surgery if the disease is considered resectable and the patient is considered surgically fit. Preoperative smoking cessation and/or preoperative pulmonary rehabilitation might improve postoperative outcomes after lung cancer surgery. The objectives of this systematic review were to determine the effectiveness of (1) preoperative smoking cessation and (2) preoperative pulmonary rehabilitation on peri- and postoperative outcomes in patients who undergo resection for lung cancer. We searched MEDLINE, PreMedline, Embase, Cochrane Library, Cinahl, BNI, Psychinfo, Amed, Web of Science (SCI and SSCI), and Biomed Central. Original studies published in English investigating the effect of preoperative smoking cessation or preoperative pulmonary rehabilitation on operative and longer-term outcomes in ≥ 50 patients who received surgery with curative intent for lung cancer were included. Of the 7 included studies that examined the effect of preoperative smoking cessation (n = 6) and preoperative pulmonary rehabilitation (n = 1) on outcomes after lung cancer surgery, none were randomized controlled trials and only 1 was prospective. The studies used different smoking classifications, the baseline characteristics differed between the study groups in some of the studies, and most had small sample sizes. No formal data synthesis was therefore possible. The included studies were marked by methodological limitations. On the basis of the reported bodies of evidence, it is not possible to make any firm conclusions about the effect of preoperative smoking cessation or of preoperative pulmonary rehabilitation on operative outcomes in patients undergoing surgery for lung cancer.

    Each year, an increasing number of elderly patients with cardiovascular disease undergoing non-cardiac surgery require careful perioperative management to minimize the perioperative risk. Perioperative cardiovascular complications are the strongest predictors of morbidity and mortality after major non-cardiac surgery. A Joint Task Force of the European Society of Cardiology (ESC) and the European Society of Anaesthesiology (ESA) has recently published revised Guidelines on the perioperative cardiovascular management of patients scheduled to undergo non-cardiac surgery, which represent the official position of the ESC and ESA on various aspects of perioperative cardiac care. According to the Guidelines effective perioperative cardiac management includes preoperative risk stratification based on preoperative assessment of functional capacity, type of surgery, cardiac risk factors, and cardiovascular function. The ESC/ESA Guidelines discourage indiscriminate routine preoperative cardiac testing, because it is time- and cost-consuming, resource-limiting, and does not improve perioperative outcome. They rather emphasize the importance of individualized preoperative cardiac evaluation and the cooperation between anesthesiologists and cardiologists. We summarize the relevant changes of the 2014 Guidelines as compared to the previous ones, with particular emphasis on preoperative cardiac testing.

    Revision total hip arthroplasty is associated with more perioperative complications and unexpected findings than are encountered during primary total hip arthroplasty. Special instruments, implants, bone grafts, and other accessories may be required to treat complex problems that arise during revision surgery. Preoperative planning is important to anticipate potential complications and to ensure that all possible needed materials are readily available during surgery. Patients and their families also should be counseled on the specific additional risk factors involved in this complex surgery. An organized approach to revision total hip arthroplasty helps to reduce surgical time, minimize risks, decrease the stress level of the entire surgical team, and to increase the rate of successful outcomes for patients.

    This study aimed to identify factors contributing to anxiety at induction of anaesthesia in children. One hundred and twenty children aged five to twelve years and scheduled for surgery requiring general anaesthesia were included. Children were interviewed and assessed prior to surgery. Parents completed anxiety measures prior to surgery and were interviewed after the induction of anaesthesia. The level of children's anxiety was determined at the time of induction of anaesthesia by the modified Yale Preoperative Anxiety Scale. Factors associated with increased levels of anxiety in the children included increased number of people in the room at induction of anaesthesia; longer waiting time between admission at the hospital and induction of anaesthesia; negative memories of previous hospital experiences; and having a mother who does not practise a religion. Suggestions for implementation of the findings and for future research are provided.

    This represents a preoperational test report for Recirculation Condenser Systems, Project W-030. Project W-030 provides a ventilation upgrade for the four Aging Waste Facility tanks. The four system provide condenser cooling water for vapor space cooling of tanks AY1O1, AY102, AZ1O1, AZ102. Each system consists of a valved piping loop, a pair of redundant recirculation pumps, a closed-loop evaporative cooling tower, and supporting instrumentation; equipment is located outside the farm on concrete slabs. Piping is routed to the each ventilation condenser inside the farm via below-grade concrete trenches. The tests verify correct system operation and correct indications displayed by the central Monitor and Control System.

    One hundred forty-one liver scans, 137 brain scans, and 112 bone scans were performed in 192 patients with clinical Stage 1 melanoma. One liver scan was interpreted as abnormal; liver biopsy of that patient showed no metastasis. There were 11 suggestive liver scans; three of the patients with suggestive liver scans had negative liver biopsies. The remaining eight patients were followed from 4 to 6 years and none of those patients developed clinical evidence of hepatic metastases. All of the brain scans were normal. Five patients had suggestive bone scans and none of those patients had manifested symptoms of osseous metastases with a follow-up of 2 to 4.5 years. This study demonstrates that the use of preoperative liver, brain and bone scan in the evaluation of patients with clinical Stage 1 melanoma is virtually unproductive.

    The anaesthetic management of patients with pre-existing pulmonary disease is a challenging task. It is associated with increased morbidity in the form of post-operative pulmonary complications. Pre-operative optimisation of lung function helps in reducing these complications. Patients are advised to stop smoking for a period of 4–6 weeks. This reduces airway reactivity, improves mucociliary function and decreases carboxy-haemoglobin. The widely used incentive spirometry may be useful only when combined with other respiratory muscle exercises. Volume-based inspiratory devices have the best results. Pharmacotherapy of asthma and chronic obstructive pulmonary disease must be optimised before considering the patient for elective surgery. Beta 2 agonists, inhaled corticosteroids and systemic corticosteroids, are the main drugs used for this and several drugs play an adjunctive role in medical therapy. A graded approach has been suggested to manage these patients for elective surgery with an aim to achieve optimal pulmonary function. PMID:26556913

    Superior sulcus tumors (SSTs), or as otherwise known Pancoast tumors, make up a clinically unique and challenging subset of non-small cell carcinoma of the lung (NSCLC). Although the outcome of patients with this disease has traditionally been poor, recent developments have contributed to a significant improvement in prognosis of SST patients. The combination of severe and unrelenting shoulder and arm pain along the distribution of the eighth cervical and first and second thoracic nerve trunks, Horner’s syndrome (ptosis, miosis, and anhidrosis) and atrophy of the intrinsic hand muscles comprises a clinical entity named as “Pancoast-Tobias syndrome”. Apart NSCLC, other lesions may, although less frequently, result in Pancoast syndrome. In the current review we will present the main characteristics of the disease and focus on the preoperative assessment. PMID:24672686

    Preoperative fasting is important to avoid morbidity and surgery delays, yet recommendations available on the Internet may be inaccurate. Our objectives were to describe the characteristics and recommendations of Internet resources on preoperative fasting and assess the quality and readability of these websites. We searched the Internet for common search terms on preoperative fasting using Google® search engines from 4 English-speaking countries (Canada, the United States, Australia, and the United Kingdom). We screened the first 30 websites from each search and extracted data from unique websites that provided recommendations on preoperative fasting. Website quality was assessed using validated tools (JAMA Benchmark criteria, DISCERN score, and Health on the Net Foundation code [HONcode] certification). Readability was scored using the Flesch Reading Ease score and Flesch-Kincaid Grade Level. A total of 87 websites were included in the analysis. A total of 48 websites (55%) provided at least 1 recommendation that contradicted established guidelines. Websites from health care institutions were most likely to make inaccurate recommendations (61%). Only 17% of websites encouraged preoperative hydration. Quality and readability were poor, with a median JAMA Benchmark score of 1 (interquartile range 0-3), mean DISCERN score 39.8 (SD 12.5), mean reading ease score 49 (SD 15), and mean grade level of 10.6 (SD 2.7). HONcode certification was infrequent (10%). Anesthesia society websites and scientific articles had higher DISCERN scores but worse readability compared with websites from health care institutions. Online fasting recommendations are frequently inconsistent with current guidelines, particularly among health care institution websites. The poor quality and readability of Internet resources on preoperative fasting may confuse patients.

    2013-01-01

    Background: The endoscopic transsphenoidal approach (eTSA) to lesions of the sellar region is typically performed jointly by neurosurgeons and otolaryngologists. Occasionally, the approach is significantly altered by sinonasal disease, anatomic variants, or previous surgery. However, there are no current guidelines that describe which physical or radiological findings should prompt a change in the plan of care. The purpose of this study was to determine the incidence of sinonasal pathology or anatomic variants noted endoscopically or by imaging that altered preoperative or intraoperative management. Methods: A retrospective review was performed of 355 consecutive patients who underwent combined neurosurgery–otolaryngology endoscopic sella approach from August 1, 2007 to April 1, 2011. Our practice in these patients involves preoperative otolaryngology clinical evaluation and MRI review. Intraoperative image guidance is not routinely used in uncomplicated eTSA. Results: The most common management alteration was the addition of image guidance based on anatomic variants on MRI, which occurred in 81 patients (35.0%). Eight patients (2.9%) were preoperatively treated with antibiotics and surgery was postponed secondary to acute or chronic purulent rhinosinusitis; two (0.7%) required functional endoscopic sinus surgery for medically refractory disease before eTSA. Five patients (1.8%) required anterior septoplasty intraoperatively for severe nasal septal deviation. Two patients (0.7%) had inverted papilloma and one patient had esthesioneuroblastoma identified preoperatively during rigid nasal endoscopy. Conclusion: This is one of the larger reviews of patients undergoing eTSA for sellar lesions and the only study that describes how intraoperative management may be altered by preoperative sinonasal evaluation. We found a significant incidence of sinonasal pathology and anatomic variants that altered routine operative planning; therefore, a thorough sinonasal evaluation

    To optimize the process for delivering and administering preoperative antibiotics in order to prevent potential adverse patient outcomes. Using a multidisciplinary quality-improvement team, an evaluation of the preoperative medication order and delivery process was conducted. Charts were reviewed by selected time periods, with winter 1994 discharges for orthopedic surgeries (n = 97) and spring 1995 discharges for open heart procedures (n = 50) being used to arrive at baseline data (n = 147). A plan was devised to mainstream the medication-use process so that it would be standardized hospitalwide. A goal of administering preoperative antibiotics within 30 to 60 minutes prior to cut time was established. Following redesign and education, a repeat chart review of orthopedic surgeries (n = 33) and open heart procedures (n = 168) was conducted during April 1997 for discharges from the same diagnosis-related groups to total (n = 201). A nearly 1,000-bed tertiary referral center and teaching hospital with three separate campuses. We identified multiple ordering mechanisms, multiple medication sources and delivery sites, multiple administration sites and administering personnel, and other logistical conflicts. Thirty-one percent of cases received antibiotics less than 30 minutes prior to start time, 39% between 30 to 60 minutes, and 30% greater than 60 minutes before start time. Following the multidisciplinary redesign and education, an increase from 39% to 61% receiving preoperative antibiotics between 30 to 60 minutes prior to surgery start time and a decrease from 31% to 18% receiving them in less than 30 minutes was documented. The percentage of patients receiving preoperative antibiotics in 60 minutes or less increased from 70% to 80%. A continuous quality-improvement approach that engages all departments involved in patient care is necessary to achieve meaningful change in complicated hospital processes.

    Acute postoperative pain may transition to persistent/chronic pain in up to 50% or more of patients after certain surgeries. Despite this concern, it is unclear that patients' preprocedure understanding and expectations are aligned with these potential outcomes. This study was designed to evaluate the extent of this alignment and the potential impact on the quality of risk/benefit discussions before procedures. Prospective survey. A large, tertiary care preoperative assessment clinic. A total of 1481 adult patients. Survey administration. The survey items evaluated patients' expectations of postoperative pain and how familiar patients were with the risk of persistent postsurgical pain based on their specific characteristics and procedure type. The overwhelming majority (80%) of patients were unaware of the risk of persistent postsurgical pain. Given the choice, most patients (65%) wanted to be informed of their risk, and 25% stated that it might even affect their decision to proceed with surgery. There is great need for health care providers to discuss the significant risk of persistent postsurgical pain with patients in the preoperative setting. Patients need to be armed with realistic data to ensure high-quality discussions of risk/benefit, align expectations with outcomes, and potentially identify high-risk groups in which preoperative intervention can reduce the likelihood or severity of persistent postoperative pain syndromes.

    To compare three anxiety scales; the anxiety visual analogue scale (VAS), the anxiety component of the Amsterdam preoperative anxiety and information scale (APAIS), and the state portion of the Spielburger state-trait anxiety inventory (STAI), for assessment of preoperative anxiety levels in same day admission patients. Patients completed the three anxiety assessment scales both before and after seeing the anesthesiologist preoperatively. The scales used were the STAI, the six-question APAIS, and the VAS. APAIS was further subdivided to assess anxiety about anesthesia (sum A), anxiety about surgery (sum S) and a combined anxiety total (i.e., sum C = sum A + sum S). These scales were compared to one another. Pearson's correlation (pair-wise deletion) was used for validity testing. Cronbach's alpha analysis was used to test internal validity of the various components of the APAIS scale. A correlation co-efficient (r) > or = 0.6 and P < 0.05 were considered significant. Four hundred and sixty three scale sets were completed by 197 patients. There was significant and positive correlation between VAS and STAI r = 0.64, P < 0.001), VAS and APAIS r = 0.6, P < 0.001), sum C and STAI r = 0.63, P < 0.001) and between VAS and sum C r = 0.61, P < 0.001). Sum C and STAI r value were consistent with repeated administration. Cronbach's alpha-levels for the anxiety components of the APAIS (sum C) and desire for information were 0.84 and 0.77 respectively. In addition to VAS, the anxiety component of APAIS (sum C) is a promising new practical tool to assess preoperative patient anxiety levels.

    We hypothesized that a novel surgical method, in which three-dimensional (3-D) preoperative planning software is generated to create a patient-specific surgical model that is used with a reusable and adjustable tool, could substantially improve the positioning accuracy of the glenoid guide pin used in total shoulder arthroplasty. We tested this method using bone models from patients with shoulder pathology and compared the results with those achieved using surgical methods representing the current standard of care. Three surgeons with a variety of surgical experience placed a guide pin in nine bone models from patients with a variety of glenohumeral arthritis severity using (1) standard instrumentation alone, (2) standard instrumentation and 3-D preoperative surgical planning, and (3) the reusable transfer device and 3-D preoperative surgical planning. A postoperative 3-D computed tomography scan of the bone model was made and registered to the preoperative plan, and the differences between the actual and planned pin locations and trajectories were measured. Use of the standard instrumentation combined with 3-D preoperative planning software improved guide pin positioning compared with standard instrumentation and preoperative planning using 2-D imaging. The accuracy of pin positioning increased by 4.5° ± 1.0° in version (p < 0.001), 3.3° ± 1.3° in inclination (p = 0.013), and 0.4 ± 0.2 mm in location (p = 0.042). Use of the adjustable and reusable device and the 3-D software improved pin positioning by a further 3.7° ± 0.9° in version, 8.1° ± 1.2° in inclination, and 1.2 ± 0.2 mm in location (p < 0.001 for all) compared with standard instrumentation and the 3-D software; the improvement compared with use of standard instrumentation with 2-D imaging was 8.2° ± 0.9° in version, 11.4° ± 1.2° in inclination, and 1.7 ± 0.2 mm in location (p < 0.001 for all).

    Introduction Over the past decades, it has been recommended that preoperative assessment mainly relies on history and physical examination rather than unnecessary laboratory tests. In Iranian hospitals, erythrocyte sedimentation rate (ESR) has been routinely measured in most of the patients awaiting major surgery, which has in turn exacted heavy costs on the health system. Therefore, the aim of the present study was to assess the preoperative routine measurement of ESR in such patients. Materials and methods This is a retrospective study, in which we evaluated the medical files of 620 patients. Patients older than 18 years, who had undergone elective heart surgery in our hospital in 2014, were included in the study. The data associated with demography, heart disease diagnosis, type of surgery, significant preoperative tests, delay or postponing of surgery and the reason for it, type and characteristics of the subspecialty consultation, and finally, postoperative complication and mortality rate were collected and analyzed. The patients were categorized into four groups according to ESR value: normal (<15 mm/h in females or <20 mm/h in males), moderately increased (<40 mm/h), severely increased (≥40 mm/h), and not measured. Results Of the 620 patients’ files, 402 were of males and 218 were of females. Demographic values and preoperative characteristics were similar in the four groups. A total of 105 consultations were given to 79 patients preoperatively, where only in five cases, the elevation in ESR was the main reason for consultation. In no other cases did the consultations result in new diagnoses. Overall, postoperative complication and mortality rate were the same in all four groups; in severely increased ESR group, on the other hand, the need for long periods of intensive care unit (ICU) and hospital stays was higher than that of other groups. Conclusion It is concluded that elevated preoperative ESR does not cancel or defer the surgery, nor does it help

    Renal failure remains a major source of morbidity after cardiac surgery. Whereas the relationship between poor renal function and worse cardiac surgical outcomes is well established, the ability to predict the impact of preoperative renal insufficiency on hospital costs and health care resource utilization remains unknown. Patient records from a statewide The Society for Thoracic Surgeons (STS) database linked with estimated cost data were evaluated for isolated coronary artery bypass graft (CABG) operations (2000 to 2012). Patients with documented preoperative renal failure/dialysis were excluded. Preoperative renal function was determined using calculated creatinine clearance (CrCl). Multivariable regression analyses utilizing restricted cubic splines evaluated the continuous relationship between CrCl and risk-adjusted outcomes. A total of 46,577 isolated CABG operations were evaluated with a median STS predicted risk of mortality score of 1.2% (interquartile range, 0.7% to 2.4%), including 9% off-pump CABG. Median CrCl was 85 mL/min (range, 2 to 120 mL/min), and median total cost was $25,011. After adjustment for preoperative risk factors, worsening CrCl (declining renal function) was highly associated with greater total costs of hospitalization (coefficient = -122, p < 0.001) and postoperative length of stay (coefficient = -0.03, p < 0.001). Furthermore, predicted total costs were incrementally increased by 10%, 20%, and 30% with worsening of CrCl from 80 mL/min to 60, 40, and 20 mL/min. As expected, decreasing CrCl was also associated with an increased risk-adjusted likelihood for hemodialysis and mortality (both p < 0.001). Preoperative renal function is highly associated with the cost of CABG. Assessment of renal function may be used to preoperatively predict cost and resource utilization. Optimizing renal function preoperatively has the potential to improve patient quality and costs by approximately 6% ($1,250) for every 10 mL/min improvement in

    Background Psychosocial interventions can improve eating behaviours and psychosocial functioning in bariatric surgery candidates. However, those that involve face-to-face sessions are problematic for individuals with severe obesity due to mobility issues and practical barriers. Objective To examine the efficacy of a pre-operative telephone-based cognitive behavioural therapy (Tele-CBT) intervention versus standard pre-operative care for improving eating psychopathology and psychosocial functioning. Methods Preoperative bariatric surgery patients (N = 47) were randomly assigned to receive standard preoperative care (n = 24) or 6 sessions of Tele-CBT (n = 23). Results Retention was 74.5% at post-intervention. Intent-to-treat analyses indicated that the Tele-CBT group reported significant improvements on the Binge Eating Scale (BES), t (22) = 2.81, p = .01, Emotional Eating Scale (EES), t (22) = 3.44, p = .002, and Patient Health Questionnaire-9 (PHQ-9), t (22) = 2.71, p = .01, whereas the standard care control group actually reported significant increases on the EES, t (23) = 4.86, p < .001, PHQ-9, t (23) = 2.75, p = .01, and General Anxiety Disorder-7 (GAD-7), t (23) = 2.93, p = .008 over the same time period. Conclusions Tele-CBT holds promise as a brief intervention for improving eating psychopathology and depression in bariatric surgery candidates. PMID:26990279

    Preoperative psychosocial assessment is the standard of care for patients seeking weight-loss surgery (WLS). However, the assessment procedure varies widely by surgery site. Comprehensive assessments can provide a wealth of information that assists both the patient and the treatment team, anticipate and prepare for challenges associated with extensive behavioral and lifestyle changes that are required postsurgery. In this review, we provide an overview of the purpose of the preoperative psychosocial assessment and domains to be included. Challenges commonly identified in the assessment are discussed, including maladaptive eating behaviors, psychiatric comorbidities, and alcohol use. Potential solutions and approaches to these challenges are provided. Additionally, patient populations requiring special consideration are presented to include adolescents, those with cognitive vulnerabilities, and aging adults. PMID:26604844

    The purpose of this study was to identify preoperative predictors of length of stay after primary total hip arthroplasty in a patient population reflecting current trends toward shorter hospitalization and using readily obtainable factors that do not require scoring systems. A retrospective review of 112 consecutive patients was performed. High preoperative pain level and patient expectation of discharge to extended care facilities (ECFs) were the only significant multivariable predictors of hospitalization extending beyond 2 days (P=0.001 and P<0.001 respectively). Patient expectation remained significant after adjusting for Medicare's 3-day requirement for discharge to ECFs (P<0.001). The study was adequately powered to analyze the variables in the multivariable logistic regression model, which had a concordance index of 0.857.

    We have noticed the possibility that preoperative spirometry may discover latent COPD patients. When COPD is discovered before operation, we can start to treat COPD promptly. Consequently, the better perioperative care is given to COPD patients. On discharge, patients are referred to their family doctors, so that they can receive COPD treatment. There activities were started in July 2012. During the initial twelve months, 90 patients of COPD II x III were discovered and treated before admission. FEV1.0 was significantly improved (1.54 l vs. 1.71 l in average) on repeated spirometry on admission. There was no adverse event in COPD treatment All patients have shown good clinical courses. Latent COPD patients can be discovered by preoperative spirometry.

    Patients presenting for surgery, be it on an elective or emergency basis, do so in the hope that the anesthetic will be without risk. Yet complications which arise are not always due to anesthesia. More often, the surgical process and factors intrinsic to the patient are major determinants of outcome. Pre-operative assessment allows review of the patient and the proposed surgery, and formation of a plan of management for the pre-, intra-, and post-operative anesthetic care. This paper provides an overview of the pre-operative assessment and management of patients who are to undergo upper abdominal surgery, with the aim of minimizing their risk of post-operative pulmonary complications. In particular, factors which contribute to the development of post-operative respiratory problems are described. PMID:1814053

    Contrary to practice guidelines, breast magnetic resonance imaging (MRI) is commonly used in the preoperative evaluation of women with breast cancer. While existing literature has found little benefit to MRI in most patients, potential downstream consequences associated with breast MRI are not well described. To describe patterns of preoperative breast MRI utilization in a health care system with universal insurance and its association with downstream investigations and clinical outcomes. This was a population-based retrospective cohort study using administrative heath care databases in Ontario, Canada (2012 population, 13.5 million) over 14 geographic regions were evaluated within the data set. Participants comprised 53 015 patients with primary operable breast cancer treated from 2003 to 2012. Use of preoperative breast MRI by year, geographic region, and breast cancer stage. Postdiagnosis imaging, biopsy, and short-term surgical outcomes were also evaluated between those who did and did not receive MRI. Overall, 14.8% of patients (7824 of 53 015) had a preoperative MRI. During the 10-year study period, MRI use increased across all stages by 8-fold (from 3% to 24%; P < .001 for trend). Factors associated with MRI use were younger age, higher socioeconomic status, higher Charlson comorbidity score, surgery performed in a teaching hospital, and fewer years of surgeon experience. Multivariate analyses showed that preoperative breast MRI was associated with higher likelihood of the following: postdiagnosis breast imaging (odds ratio [OR], 2.09; 95% CI, 1.92-2.28), postdiagnosis breast biopsies (OR, 1.74; 95% CI, 1.57-1.93), postdiagnosis imaging to assess for distant metastatic disease (OR, 1.51; 95% CI, 1.42-1.61), mastectomy (OR, 1.73; 95% CI, 1.62-1.85), contralateral prophylactic mastectomy (OR, 1.48; 95% CI, 1.23-1.77), and a greater than 30-day wait to surgery (OR, 2.52; 95% CI, 2.36-2.70) (all ORs are adjusted). Preoperative breast MRI use has increased

    Medical information is mandatory before any medical procedure, including pediatric anesthesia. Preoperative information covers many aspects, including medico-psychologic and judicial aspects. When the patient is a child, information must be delivered to the parents in priority. However, the French law has given a particular attention to the opinion of the child. In 70% of the cases, preoperative anxiety of the parents is more related to anesthesia than to the surgical procedure itself. We have to explain the most frequent adverse effects, as well as the more severe and well known complications to the parents, even though they are very infrequent. The only cases where preoperative information is not required are: emergency cases and refusal of the patient or the parents to be informed. While information is necessarily oral, it may be completed using a written document. The quality of the preoperative information directly influences the quality of the psychological preoperative preparation of the parents, and thereafter of the child. Preoperative preparation programs have been developed, but controversial results have been observed. The great majority of the studies on preoperative programs were performed in the USA, where the demand for preoperative information is very important. It is far from sure that the results of all these studies may be extrapolated to French parents, and French studies are needed.

    The Pharmacovigilance Center of the University of Florence conducted a survey across 3 hospitals in Tuscany (Empoli, Florence, and Prato) on a sample population consisting of 478 patients admitted to the hospital for a preoperative assessment before surgical intervention. The aim of the study was to assess the concomitant use of herbal remedies (HRs) and prescribed medications and to evaluate the most important potential interactions. Almost 50% of the patients surveyed-238 of 478 (49.8 %)-used at least 1 HR. Among them, 55 (23.1%) were actually exposed to at least 1 potential interaction. In particular, 42 participants had an HR-drug interaction and 17 participants had a dietary supplement drug interaction. A large percentage of patients undergoing surgery take HRs that could potentially interact with drugs administered perioperatively. Antihypertensive, antiplatelet, anticoagulant, and central nervous system (CNS) agents were the main products involved. The use of HRs is not devoid of risks and adverse effects due to potential interactions that may be serious or even lifethreatening. HR-drug interactions should be deeply investigated, especially in high-risk patient populations. Health care professionals should pay close attention and always investigate the consumption of HRs among their patients.

    In implant placement, different bone densities require different implant types in order to achieve maximum stability. Therefore, careful preoperative planning is essential to diagnose and/or augment the bone, to select the correct size and type of implant for each individual case, and to establish the appropriate surgical protocol. This paper and presentation discuss the essentials for establishing such protocol, ie, the quality and quantity of bone, type and size of implants, surgery, progressive loading, and shifting of the mastication forces. Serious errors in planning first appear as short-term failures, and they indicate inadequacy in osseointegration in the healing phase or overloading caused by the superstructure. Less grave errors occur later as long-term failures, due to the width, depth, and density of the bone and the angulation of the implant. Appropriate components have to be used for different types of bone: Uncoated screws are the best solution for D1 and D2 types of bone; coated screws should be used in the presinus area and after nerve transpositioning. Cylindrical implants are best suited for subantral augmentation, using a narrow drill; the bone bed is progressively widened by a conic osteotome, and the technique provides a good stability. Free gingival transplant is indicated in cases with insufficient keratinized gingiva. Masticatory overloading can be avoided by reducing the occlusal table, decreasing cusp inclination, and anteriorizing the upper mastication areas.

The searches identified 9900 titles and, after excluding duplicates, 6433 titles were initially screened. After the initial title screen, 6266 were excluded. Abstracts were screened for 167 studies and 33 articles were identified as meeting the inclusion criteria, of which 13 were included in the review after an assessment of the complete manuscripts.Seven trials evaluating IE nutrition were included in the review, of which 6 were combined in a meta-analysis. These studies showed a low to moderate level of heterogeneity and significantly reduced total post-operative complications (risk ratio (RR) 0.67 CI 0.53 to 0.84). Three trials evaluating PN were included in a meta-analysis and a significant reduction in post-operative complications was demonstrated (RR 0.64 95% CI 0.46 to 0.87) with low heterogeneity, in predominantly malnourished participants. Two trials evaluating enteral nutrition (RR 0.79, 95% CI 0.56 to 1.10) and 3 trials evaluating standard oral supplements (RR 1.01 95% CI 0.56 to 1.10) were included, neither of which showed any difference in the primary outcomes. There have been significant benefits demonstrated with pre-operative administration of IE nutrition in some high quality trials. However, bias was identified which may limit the generalizability of these results to all GI surgical candidates and the data needs to be placed in context with other recent innovations in surgical management (eg-ERAS). Some unwanted effects have also been reported with components of IE nutrition in critical care patients and it is unknown whether there would be detrimental effects by administering IE nutrition to patients who could require critical care support after their surgery. The studies evaluating PN demonstrated that the provision of PN to predominantly malnourished surgical candidates reduced post

    Retrospective study. To evaluate the prognostic value of preoperative pulmonary function test (PFT) for postoperative pulmonary complications and to identify the operability associated with severely decreased forced vital capacity (FVC) (<30%) status in flaccid neuromuscular scoliosis. The preoperative PFT, especially more than 30% FVC, is known as a critical factor for the operability of flaccid neuromuscular scoliosis. But only one study reported that patients with pre-existing respiratory failure on nocturnal noninvasive ventilation can undergo an operation for deformity correction without mortality and severe complications. A total of 74 patients (45 male and 29 female) presented with flaccid neuromuscular scoliosis. For all patients, preoperative PFTs were evaluated and subdivided into three groups (<30% FVC, 30%-50% FVC, and >50% FVC). Then postoperative pulmonary complications, pneumothorax, pneumonia, atelectasis, prolonged ventilator care in the intensive care unit (more than 72 hours), and postoperative tracheostomy were evaluated. Among these patients, 59 had muscular dystrophy; 5, spinal muscular atrophy; 2, cerebral palsy; and 8, others. The mean age at surgery was 16.8 years (range, 5-32 years). The mean preoperative Cobb angle was 54.6° (16°-135°). The overall postoperative pulmonary complication rate was 31% (23 complications in 74 patients). The less than 30% FVC group had 6 complications among 18 patients; the 30% to 50% FVC group had 7 complications among 18 patients; and the more than 50% FVC group had 10 complications among 38 patients. There were no deaths during the perioperative period. There is no statistical difference between the three groups (P = 0.6195). Patients with flaccid neuromuscular scoliosis can undergo an operation for deformity correction regardless of the severely decreased pulmonary function.

    We sought to identify preoperative and intraoperative predictors of immediate extubation (IE) after open heart surgery in neonates. The effect of IE on the postoperative intensive care unit (ICU) length of stay (LOS), cost of postoperative ICU care, operating room turnover, and reintubation rates was assessed. Patients younger than 31 days who underwent cardiac surgery with cardiopulmonary bypass (January 2010 to December 2013) at a tertiary-care children's hospital were studied. Immediate extubation was defined as successful extubation before termination of anesthetic care. Data on preoperative and intraoperative variables were compared using descriptive, bivariate, and multivariate statistics to identify the predictors of IE. Propensity scores were used to assess effects of IE on ICU LOS, the cost of ICU care, reintubation rates, and operating room turnover time. One hundred forty-eight procedures done at a median age of 7 days resulted in 45 IEs (30.4%). The IE rate was 22.2% with single-ventricle heart disease. Independent predictors of IE were the absence of the need for preoperative ventilatory assistance, higher gestational age, anesthesiologist, and shorter cardiopulmonary bypass. Immediate extubation was associated with shorter ICU LOS (8.3 versus 12.7 days; p < 0.0001) and lower cost of ICU care (mean postoperative ICU charges, $157,449 versus $198,197; p < 0.0001) with no significant difference in the probability of reintubation (p = 0.7). Immediate extubation was associated with longer operating room turnover time (38.4 versus 46.7 minutes; p = 0.009). Immediate extubation was accomplished in 30.4% of neonates undergoing open heart surgery involving cardiopulmonary bypass. Immediate extubation was associated with lesser ICU LOS, postoperative ICU costs, and minimal increase in operating room turnover time, but without an increase in reintubation rates. Low gestational age, preoperative ventilatory support requirement, and prolonged cardiopulmonary

    Study Objectives: To describe preoperative and postoperative sleep disruption and its relationship to postoperative delirium. Design: Prospective cohort study with 6 time points (3 nights pre-hospitalization and 3 nights post-surgery). Setting: University medical center. Patients: The sample consisted of 50 English-speaking patients ≥ 40 years of age scheduled for major non-cardiac surgery, with an anticipated hospital stay ≥ 3 days. Interventions: None. Measurements and results: Sleep was measured before and after surgery for a total of 6 days using a wrist actigraph to quantify movement in a continuous fashion. Postoperative delirium was measured by a structured interview using the Confusion Assessment Method. Sleep variables for patients with (n = 7) and without (n = 43) postoperative delirium were compared using the unpaired Student t-tests or χ2 tests. Repeated measures analysis of variance for the 6 days was used to examine within-subject changes over time and between group differences. The mean age of the patients was 66 ± 11 years (range 43–91 years), and it was not associated with sleep variables or postoperative delirium. The incidence of postoperative delirium observed during any of the 3 postoperative days was 14%. For the 7 patients who subsequently developed postoperative delirium, wake after sleep onset (WASO) as a percentage of total sleep time was significantly higher (44% ± 22%) during the night before surgery compared to the patients who did not subsequently developed delirium (21% ± 20%, p = 0.012). This sleep disruption continued postoperatively, and to a greater extent, for the first 2 nights after surgery. Patients with WASO < 10% did not experience postoperative delirium. Self-reported sleep disturbance did not differ between patients with vs. without postoperative delirium. Conclusions: In this pilot study of adults over 40 years of age, sleep disruption was more severe before surgery in the patients who experienced postoperative

    Objective Total laryngectomy (TL) is a high-cost procedure with patients at risk for significant postoperative health care use. Face-to-face preoperative counseling provided by speech-language pathologists is a relatively inexpensive intervention that may improve care quality and decrease costs. We evaluated if preoperative counseling for patients undergoing TL was associated with differences in length of stay (LOS), use of the emergency department (ED), or unplanned readmissions within 30 days of discharge. A secondary analysis identified predictors of these 3 outcomes. Study Design Case series with chart review. Setting Academic medical center in the United States. Subjects and Methods Patients were included if they underwent TL from 2011 to 2015. Patient demographics and comorbidities, surgical characteristics, and perioperative care data were retrieved and analyzed for 116 patients. Univariate and multivariate models were constructed for 3 outcomes. Results LOS was significantly lower for patients receiving counseling (-3.0 days, P = .02). No differences were observed in rates of 30-day ED visits or unplanned readmissions. Care provided by high-volume surgeons was associated with decreased LOS ( P = .005), while having postoperative complications increased LOS ( P < .001). High rates of ED visits (12.1%) and readmissions (20.6%) were observed. Discharge to inpatient rehabilitation and the patient's home distance from the institution were predictors of ED visits. TL as salvage therapy and occurrence of postoperative complications were risk factors for readmission. Conclusion Preoperative counseling was associated with marked reduction in LOS following TL without increased readmissions, which suggests that it may promote safe, earlier patient readiness for discharge.

    This study investigated the effect of socioeconomic deprivation on preoperative disease and outcome following unicompartmental knee replacement (UKR). 307 Oxford UKRs implanted between 2008 and 2013 under the care of one surgeon using the same surgical technique were analysed. Deprivation was quantified using the Northern Ireland Multiple Deprivation Measure. Preoperative disease severity and postoperative outcome were measured using the Oxford Knee Score (OKS). There was no difference in preoperative OKS between deprivation groups. Preoperative knee range of motion (ROM) was significantly reduced in more deprived patients with 10° less ROM than least deprived patients. Postoperatively there was no difference in OKS improvement between deprivation groups (p=0.46), with improvements of 19.5 and 21.0 units in the most and least deprived groups respectively. There was no significant association between deprivation and OKS improvement on unadjusted or adjusted analysis. Preoperative OKS, Short Form 12 mental component score and length of stay were significant independent predictors of OKS improvement. A significantly lower proportion of the most deprived group (15%) reported being able to walk an unlimited distance compared to the least deprived group (41%) one year postoperatively. More deprived patients can achieve similar improvements in OKS to less deprived patients following UKR. Copyright © 2015 Elsevier B.V. All rights reserved.

    A cephalosomatic anastomosis (CSA; also called HEAVEN: head anastomosis venture) has been proposed as an option for patients with neurological impairments, such as spinal cord injury (SCI), and terminal medical illnesses, for which medicine is currently powerless. Protocols to prepare a patient for life after CSA do not currently exist. However, methods used in conventional neurorehabilitation can be used as a reference for developing preparatory training. Studies on virtual reality (VR) technologies have documented VR's ability to enhance rehabilitation and improve the quality of recovery in patients with neurological disabilities. VR-augmented rehabilitation resulted in increased motivation towards performing functional training and improved the biopsychosocial state of patients. In addition, VR experiences coupled with haptic feedback promote neuroplasticity, resulting in the recovery of motor functions in neurologically-impaired individuals. To prepare the recipient psychologically for life after CSA, the development of VR experiences paired with haptic feedback is proposed. This proposal aims to innovate techniques in conventional neurorehabilitation to implement preoperative psychological training for the recipient of HEAVEN. Recipient's familiarity to body movements will prevent unexpected psychological reactions from occurring after the HEAVEN procedure.

  5. The Preoperative Patient With a Systolic Murmur

    2015-01-01

    Context: Patients with undifferentiated systolic murmurs present commonly during the perioperative period. Traditional bedside assessment and auscultation has not changed significantly in almost 200 years and relies on interpreting indirect acoustic events as a means of evaluating underlying cardiac pathology. This is notoriously inaccurate, even in expert cardiology hands, since many different valvular and cardiac diseases present with a similar auditory signal. Evidence Acquisition: The data on systolic murmurs, physical examination, perioperative valvular disease in the setting of non-cardiac surgery is reviewed. Results: Significant valvular heart disease increases perioperative risk in major non-cardiac surgery and increases long term patient morbidity and mortality. We propose a more modern approach to physical examination that incorporates the use of focused echocardiography to allow direct visualization of cardiac structure and function. This improves the diagnostic accuracy of clinical assessment, allows rational planning of surgery and anaesthesia technique, risk stratification, postoperative monitoring and appropriate referral to physicians and cardiologists. Conclusions: With a thorough preoperative assessment incorporating focused echocardiography, anaesthetists are in the unique position to enhance their role as perioperative physicians and influence short and long term outcomes of their patients.

    A cephalosomatic anastomosis (CSA; also called HEAVEN: head anastomosis venture) has been proposed as an option for patients with neurological impairments, such as spinal cord injury (SCI), and terminal medical illnesses, for which medicine is currently powerless. Protocols to prepare a patient for life after CSA do not currently exist. However, methods used in conventional neurorehabilitation can be used as a reference for developing preparatory training. Studies on virtual reality (VR) technologies have documented VR's ability to enhance rehabilitation and improve the quality of recovery in patients with neurological disabilities. VR-augmented rehabilitation resulted in increased motivation towards performing functional training and improved the biopsychosocial state of patients. In addition, VR experiences coupled with haptic feedback promote neuroplasticity, resulting in the recovery of motor functions in neurologically-impaired individuals. To prepare the recipient psychologically for life after CSA, the development of VR experiences paired with haptic feedback is proposed. This proposal aims to innovate techniques in conventional neurorehabilitation to implement preoperative psychological training for the recipient of HEAVEN. Recipient's familiarity to body movements will prevent unexpected psychological reactions from occurring after the HEAVEN procedure. PMID:28540125

    During the past decades, encouraging progress has been made in the prevention of surgical site infections (SSI). However, as SSI still occur today, strategic prevention measures such as standardized skin antisepsis must be implemented and rigorously promoted. Recent discoveries in skin physiology necessitate the development of novel antiseptic agents and procedures in order to ameliorate their efficacy. In particular, alternate target structures in the skin need to be taken into consideration for the development of the next generation of antiseptics. Recent investigations have shown that a high number of microorganisms are located within and in the close vicinity of the hair follicles. This suggests that these structures are an important reservoir of bacterial growth and activity in human skin. To date, it has not been fully elucidated to what extent conventional liquid antiseptics sufficiently target the hair follicle-related microbial population. Modern technologies such as tissue-tolerable plasma (TTP) have been tested for their potential antiseptic efficiency by reducing the bacterial load in the skin and in the hair follicles. First experiments using liposomes to deliver antiseptics into the hair follicles have been evaluated for their potential clinical application. The present review evaluates these two innovative methods for their efficacy and applicability in preoperative skin antiseptics.

    Impairment of the surgical view by bleeding in endoscopic ethmoidectomy for chronic rhinosinusitis with nasal polyps (CRSwNP) contributes to the risk of skull base injuries. The aim of this study was to investigate the effect of a short course of a systemic corticoid treatment on bleeding and surgical field quality during endoscopic ethmoidectomy for CRSwNP. A prospective study was conducted on 40 patients. Before surgery, 21 of them (group B) were treated with 1 mg/kg per day of prednisolone for seven days. They were compared with the 19 other patients (group A) on intraoperative blood loss and surgery duration. The two groups shared identical clinical features (Lidholdt endoscopic grading). There was no statistical difference in terms of bleeding, although the Lund-Mackay CT score was higher in group B (19/24 vs. 21/24, p=0.05). The surgical procedure was shorter in group B (72 min vs. 85 min, p=0.05). Preoperative treatment with systemic corticosteroids does not seem to reduce surgical blood loss. However, we noted a decrease in the procedure's duration. By reducing mucous inflammation, this treatment could improve the local conditions and help the surgeon in the mucous eradication.

    Coronary heart disease is common in Type 2 diabetes and often requires cardiac surgery. However poorer outcomes have been reported including increased rates of post-operative infection and prolonged hospital stay. The aim of the study was to determine the feasibility and acceptability of a specialist consultation model (pre-operative medical and educational intervention) for type 2 diabetes in the cardiac surgery setting. Twenty four patients were assigned usual care or to the intervention group. The intervention group were assessed by a diabetes clinical nurse consultant, dietitian, and endocrinologist during a pre-operative visit. Specific diabetes questionnaires were administered, education was delivered, and protocol-driven changes to the medical regimen were instituted. Length of stay, incidence of post-operative complications, and number of post-operative inpatient review endocrinology visits required were recorded. Twenty four patients with a pre-operative HbA(1c) greater than 6.5% (48 mmol/mol) were studied (17 males and 7 females). In the usual care group (n = 15), HbA(1c) pre-operatively was 7.2% (55.2 mmol/mol) compared to 10.1% (86.9 mmol/mol) in the intervention group (n = 9). Six weeks post-operatively HbA(1c) fell significantly in the intervention group by 1.9% (to 8.2% [66.1 mmol/mol]) compared to a reduction of 1.2% (to 7.0% [53 mmol/mol]) in the usual care group (p < 0.05). No significant differences were observed in length of stay in intensive care or in total hospital stay between the groups: length of ICU stay 54 h for intervention versus 47 h for usual care, total hospital stay (mean 8 days for both); or in rates of post-operative infection. Differences were seen between in the diabetes questionnaires: in the Problem Areas in Diabetes questionnaire and in the Diabetes Treatment Satisfaction Questionnaire (p = 0.048). This small pilot feasibility study suggests there is potential benefit in the acute optimisation of diabetes treatment before

    Routine ordering of pre-operative investigations yields a low true positive rate and is not cost effective. In this study, case notes of 251 adults who underwent elective surgery were reviewed. Pre-operative investigations were classified as 'indicated' or 'not indicated', based on the national guidelines. Only 56% of all tests done were indicated. The overall rates of expected and unexpected abnormal values from pre-operative blood investigations were 51.1% and 34.4% respectively. This study found that selective testing based on guidelines was beneficial. However, the results also suggest that the local guidelines need to be reviewed.

    Nutritional deficiencies have to be considered as an independent risk factor for postoperative morbidity. Peri-operative nutritional support reduce this risk in elective abdominal surgery for cancer and cardiac surgery. Preoperative nutritional support for 7-10 days reduce postoperative complications in undernourished patients by 10% but is not operant when administered after surgery. Enteral route is as effective. Recent studies using immunonutrients conclude that a short preoperative oral intake is able to reduce complications even in well-nourished patients. Then, a preoperative nutritional screening must be routinely performed leading to a nutritional programme.

    To describe the conjunctival bacterial spectrum of our patients undergoing intraocular surgery and their antibiotic sensitivity during the study period. A retrospective study of preoperative conjunctival culture of patients consecutively scheduled for intraocular surgery from 21 February 2011 to 1 April 2013. Specimens were directly seeded onto blood-agar and MacConkey-agar (aerobiosis incubation, 2 days), and on chocolate-agar (6% CO2 incubation, 7 days). The identified bacteria were divided into 3 groups according to their origin; the bacteria susceptibility tests were performed on those more pathogenic and on some of the less pathogenic when more than 5 colonies were isolated. The sensitivity of the exigent growing bacteria was obtained with disk diffusion technique, and for of the non-exigent bacteria by determining their minimum inhibitory concentration. The Epidat 3.1 program was used for statistical calculations. A total of 13,203 bacteria were identified in 6,051 cultures, with 88.7% being typical colonizers of conjunctiva (group 1), 8.8% typical of airways (group 2), and the remaining 2.5% of undetermined origin (group 3). 530 cultures (8.8%) were sterile. The sensitivity of group 1 was: 99% vancomycin, 95% rifampicin, 87% chloramphenicol, 76% tetracycline. Levels of co-trimoxazole, aminoglycosides, quinolones, β-lactams and macrolides decreased since 2007. The group 2 was very sensitive to chloramphenicol, cefuroxime, rifampicin, ciprofloxacin and amoxicillin/clavulanate. In group 3, to levofloxacin 93%, ciprofloxacin 89%, tobramycin 76%, but ceftazidime 53% and cefuroxime 29% decreased. None of the tested antibiotics could eradicate all possible conjunctival bacteria. Bacteria living permanently on the conjunctiva (group 1) have achieved higher resistance than the eventual colonizers. Copyright © 2013 Sociedad Española de Oftalmología.

    The identification and removal of malignant central compartment lymph nodes (MCLN) is important to minimize the risk of persistent or recurrent local disease in patients with papillary thyroid cancer (PTC). While the diagnostic accuracy of preoperative ultrasound for the assessment of lateral compartment node metastases is well recognized, its role in the identification of central compartment node metastases in patients with PTC is less established. This study delineates the utility of high-resolution ultrasound (HUS) for the assessment of MCLN in patients with PTC. A retrospective chart review was performed of 227 consecutive patients who underwent total thyroidectomy for biopsy-proven PTC by a single endocrine surgeon in an academic tertiary care center between 2004 and 2014. Preoperative sonographic results were compared to postoperative pathology reports to determine the accuracy of HUS for the assessment of MCLN. Statistical analysis also included sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). HUS identified abnormal central compartment nodes in 51 (22.5%) patients. All 227 patients underwent a careful central compartment node exploration. One hundred and four (45.8%) patients had MCLN identified by surgery, of whom 65 (62.5%) had a negative preoperative central compartment HUS. The sensitivity and specificity of preoperative HUS for the assessment of MCLN were 0.38 and 0.90, respectively. The PPV and NPV were 0.76 and 0.63, with an accuracy of 0.66. Preoperative HUS is quite specific for the identification of MCLN in patients with PTC. The present findings emphasize, however, that a negative HUS does not obviate the need for careful exploration of the central compartment to minimize the risk of persistent or recurrent local disease.

    Abstract Acute kidney injury (AKI) after cardiac surgery is a common and serious complication. Although lower than normal serum bicarbonate levels are known to be associated with consecutive renal function deterioration in patients with chronic kidney injury, it is not well-known whether preoperative low serum bicarbonate levels are associated with the development of AKI in patients who undergo cardiac surgery. Therefore, the clinical implication of preoperative serum bicarbonate levels on AKI occurrence after cardiac surgery was investigated. Patients who underwent coronary artery bypass or valve surgery at Yonsei University Health System from January 2013 to December 2014 were enrolled. The patients were divided into 3 groups based on preoperative serum bicarbonate levels, which represented group 1 (below normal levels) <23 mEq/L; group 2 (normal levels) 23 to 24 mEq/L; and group 3 (elevated levels) >24 mEq/L. The primary outcome was the predicated incidence of AKI 48 hours after cardiac surgery. AKI was defined according to Acute Kidney Injury Network criteria. Among 875 patients, 228 (26.1%) developed AKI within 48 hours after cardiac surgery. The incidence of AKI was higher in group 1 (40.9%) than in group 2 (26.5%) and group 3 (19.5%) (P < 0.001). In addition, the duration of postoperative stay in a hospital intensive care unit (ICU) was longer for AKI patients and for those in the low-preoperative-serum-bicarbonate-level groups. A multivariate logistic regression analysis showed that low preoperative serum bicarbonate levels were significantly associated with AKI even after adjustment for age, sex, hypertension, diabetes mellitus, operation type, preoperative hemoglobin, and estimated glomerular filtration rate. In conclusion, low serum bicarbonate levels were associated with higher incidence of AKI and prolonged ICU stay. Further studies are needed to clarify whether strict correction of bicarbonate levels close to normal limits may have a

    To determine the factors contributing to increased rate of ruptured abdominal aortic aneurysms (AAAs) for elderly poor patients. Medicare claims were analyzed for patients who underwent AAA repair from 2006 to 2009 with preoperative abdominal imaging. Repair for ruptured versus intact AAAs was our primary outcome measure. We used logistic regression to determine the relationship between Medicaid eligibility and the risk of rupture, sequentially adding variables related to patient characteristics, socioeconomic status, receipt of preoperative AAA surveillance, and hospital AAA volume. We then estimated the proportional effect of each factor. No differences in rupture were observed in women based on payer status. Medicaid-eligible men were more likely to present with ruptured AAA (odds ratio [OR] 2.42, 95% confidence interval [CI] 1.65-3.52). After adjusting for patient and hospital factors, the poor remained at higher risk for rupture (OR 1.5, 95% CI 1.10-2.26). This disparate risk of rupture was more commonly observed in hospitals treating a higher proportion of Medicaid-eligible patients. We estimate that 36% of the observed disparity in rupture for the elderly poor is explained by patient factors, 27% by gaps in surveillance, 9% by hospital factors, and <1% by socioeconomic factors. Incomplete preoperative surveillance is a key contributor to increased rupture of AAA in the elderly poor. Efforts aimed at improving disparities must include consistent access to medical care.

    Advantages of unicondylar knee arthroplasty (UKA) over total knee arthroplasty include rapid recovery and shorter lengths of stay following surgery. Patients requiring extended postoperative care fail to recognize these benefits. Patient-reported outcome measures have proved useful in predicting outcomes following joint arthroplasty. The purpose of this study was to identify and report preoperative patient-reported outcome measures and clinical variables that predict discharge to skilled nursing facilities following UKA. A prospective cohort of 174 patients was used to collect 36-Item Short Form scores and objective clinical data. Univariate and multivariate analysis with backward elimination were conducted to find a predictive risk model. The predictive model reported (78.7% concordance, receiver operating characteristic curve c-statistic 0.719, P = .0016) demonstrates that risk factors for discharge to skilled nursing facilities are: older age (odds ratio 4.18; 95% confidence interval [CI] 1.256-13.911, P = .019), bilateral UKA procedures (odds ratio 1.887; 95% CI 1.054-3.378, P = .0326) and lower patient-reported preoperative 36-Item Short Form physical function scores (odds ratio 0.968; CI 0.938-1, P = .0488). The information presented here regarding possible patient disposition following UKA could aid informed decision-making regarding patients' short-term needs following surgery and help streamline preoperative planning.

    Background. Preoperative fasting (POF) is physiologically and precautionary important during anesthesia and surgery. POF from midnight has been practiced despite the recommended shorter practice. Objective. Assessing preoperative fasting among adult patients scheduled for elective surgery at Kenyatta National Hospital (KNH). Methods. A descriptive cross-sectional study involving 65 surgical patients. A questionnaire of mixed questions on demographics, reasons, source of instructions, opinion on instructions, time, premedication practices, outcome, and complains on NPO was used. Analysis was quantitatively done with SPSS v. 22. Ethical approval was obtained from KNH-UoN ERC. Results. Of the respondents 93.8% lacked knowledge on the correct reasons for POF and felt that the instructions were unclear and less important <50%. POF instructions were administered by nurses 80%, anesthetists 15%, and surgeons 5%. Most of respondents (73.8%) fasted > 15 hours. The POF outcomes were rated moderately challenging as follows: prolonged wait for surgery 44.6%, thirst 43.1%, hunger 36.9%, and anxiety 29.2%. Conclusion. Nurses are critical in providing POF instructions and care, and patient knowledge level is a mirror reflection of the quality of interventions. This underscores the need to build capacity for nurses and strengthen the health system to offer individualized preoperative interventions as well as monitoring and clinical auditing of fasting practices.

    The hypothesis that optimizing hemodynamics using pulmonary artery (PA) catheter (preoperative 'tune-up') would improve outcome in patients undergoing limb-salvage arterial surgery was tested. Eighty-nine patients were randomized to preoperative tune-up either in the surgical intensive care unit (SICU) (group 1) or the preinduction room (group 2) or to control (group 3). The tune-up consisted of fluid loading, afterload reduction, and/or inotropic support to achieve predetermined endpoints. Patients with a PA catheter had significantly fewer adverse intraoperative events (p less than 0.05), less postoperative cardiac morbidity (p less than 0.05), and less early graft thrombosis (p less than 0.05) than the control group. The overall study mortality rate was 3.4%, with a mortality rate of 9.5% in the control group and 1.5% in the PA catheter groups. There were no differences in ICU length of stay (LOS), hospital LOS, or total hospital costs, although the percentage of cost from complications was higher in group 3 (p greater than 0.05). In this group of patients, preoperative cardiac assessment and optimization is associated with improved outcome. PMID:1929610

    The aim of this study was to analyse preoperative risk factors for mortality or intensive care unit admission to describe severe peritonitis. This was a single academic centre retrospective study of consecutive adult patients operated for diffuse secondary peritonitis between 2012 and 2013. Patients with appendicitis or cholecystitis were excluded. Independent risk factors were identified using binary and ordinal logistic regression. A total of 223 patients were analysed. Overall 30-day mortality was 14.5 %. Postoperatively, 32.3 % of patients were admitted into the intensive care unit (ICU). Independent risk factors for severe peritonitis were septic shock (odds ratio (OR) 37.94, 95 % confidence interval (CI) 14.52-99.13), chronic kidney insufficiency (OR 5.98 (95 % CI 1.56-22.86), severe sepsis (OR 4.80, 95 % CI 2.10-10.65) and cardiovascular disease (OR 2.58, 95 % CI 1.22-5.47). Patients lacking these factors had no mortality. ICU admission was refused in 24 (10.8 %) patients with 70.8 % mortality. In a subgroup of patients without treatment limitations (n = 190), independent risk factors for weighted outcome of ICU admission or mortality were septic shock (OR 11.89, 95 % CI 4.98-28.40), severe sepsis (OR 5.56, 95 % CI 2.39-12.89), metastatic malignant disease or lymphoma (OR 3.11, 95 % CI 1.34-7.20) and corticosteroid use (OR 2.98, 95 % CI 1.18-7.51). When receiving full level of care, patients with preoperative organ dysfunctions in this subgroup had 8.2 % 30-day mortality. Preoperative organ dysfunctions, chronic kidney insufficiency and cardiovascular disease are the most important risk factors for severe peritonitis. Without these risk factors, patients had no mortality.

    AIM: To evaluate donation after circulatory death (DCD) orthotopic liver transplant outcomes [hypoxic cholangiopathy (HC) and patient/graft survival] and donor risk-conditions. METHODS: From 2003-2013, 45 DCD donor transplants were performed. Predonation physiologic data from UNOS DonorNet included preoperative systolic and diastolic blood pressure, heart rate, pH, SpO2, PaO2, FiO2, and hemoglobin. Mean arterial blood pressure was computed from the systolic and diastolic blood pressures. Donor preoperative arterial O2 content was computed as [hemoglobin (gm/dL) × 1.37 (mL O2/gm) × SpO2%) + (0.003 × PaO2)]. The amount of preoperative donor red blood cell transfusions given and vasopressor use during the intensive care unit stay were documented. Donors who were transfused ≥ 1 unit of red-cells or received ≥ 2 vasopressors in the preoperative period were categorized as the red-cell/multi-pressor group. Following withdrawal of life support, donor ischemia time was computed as the number-of-minutes from onset of diastolic blood pressure < 60 mmHg until aortic cross clamping. Donor hypoxemia time was the number-of-minutes from onset of pulse oximetry < 80% until clamping. Donor hypoxia score was (ischemia time + hypoxemia time) ÷ donor preoperative hemoglobin. RESULTS: The 1, 3, and 5 year graft and patient survival rates were 83%, 77%, 60%; and 92%, 84%, and 72%, respectively. HC occurred in 49% with 16% requiring retransplant. HC occurred in donors with increased age (33.0 ± 10.6 years vs 25.6 ± 8.4 years, P = 0.014), less preoperative multiple vasopressors or red-cell transfusion (9.5% vs 54.6%, P = 0.002), lower preoperative hemoglobin (10.7 ± 2.2 gm/dL vs 12.3 ± 2.1 gm/dL, P = 0.017), lower preoperative arterial oxygen content (14.8 ± 2.8 mL O2/100 mL blood vs 16.8 ± 3.3 mL O2/100 mL blood, P = 0.049), greater hypoxia score >2.0 (69.6% vs 25.0%, P = 0.006), and increased preoperative mean arterial pressure (92.7 ± 16.2 mmHg vs 83.8 ± 18.5 mmHg, P = 0

    This paper describes the design and implementation of a pen-based computer system for remote preoperative data collection. The system is envisaged to be used by anaesthesia staff at different hospital scenarios where pre-operative data are generated. Pen-based technology offers important advantages in terms of portability and human-computer interaction, as direct manipulation interfaces by direct pointing, and "notebook user interfaces metaphors". Being the human factors analysis and user interface design a vital stage to achieve the appropriate user acceptability, a methodology that integrates the "usability" evaluation from the earlier development stages was used. Additionally, the selection of a pen-based computer system as a portable device to be used by health care personnel allows to evaluate the appropriateness of this new technology for remote data collection within the hospital environment. The work presented is currently being realised under the Research Project "TANIT: Telematics in Anaesthesia and Intensive Care", within the "A.I.M.--Telematics in Health CARE" European Research Program.

    Perioperative haemorrhage negatively affects patient outcomes and results in substantial consumption of health-care resources. Plasma transfusions are often administered to address abnormal preoperative coagulation tests, with the hope to mitigate bleeding complications. We aimed to assess the associations between preoperative plasma transfusion and bleeding complications in patients with elevated international normalised ratio (INR) undergoing non-cardiac surgery. We did an observational study in a consecutive sample of adult patients undergoing non-cardiac surgery with preoperative INR greater than or equal to 1·5. The exposure of interest was transfusion of preoperative plasma for elevated INR. The primary outcome was WHO grade 3 bleeding in the early perioperative period (from entry into the operating room until 24 h following exit from operating room). Hypotheses were tested with univariate and propensity-matched analyses. We did multiple sensitivity analyses to further evaluate the robustness of study findings. Between Jan 1, 2008, and Dec 31, 2011, we identified 1234 (8·4%) of 14 743 patients who had an INR of 1·5 or above and were included in this investigation. Of 1234 study participants, 139 (11%) received a preoperative plasma transfusion. WHO grade 3 bleeding occurred in 73 (53%) of 139 patients who received preoperative plasma compared with 350 (32%) of 1095 patients who did not (odds ratio [OR] 2·35, 95% CI 1·65-3·36; p<0·0001). Among the propensity-matched cohort, 65 (52%) of 125 plasma recipients had WHO grade 3 bleeding compared with 97 (40%) of 242 of those who did not receive preoperative plasma (OR 1·75, 95% CI 1·09-2·81; p=0·021). Results from multiple sensitivity analyses were qualitatively similar. Preoperative plasma transfusion for elevated international normalised ratios was associated with an increased frequency of perioperative bleeding complications. Findings were robust in the sensitivity analyses, suggestive that more

    Despite recent improvements in perinatal care, the incidence of neonatal brachial plexus palsy (NBPP) remains relatively common. CT myelography is currently considered to be the optimal imaging modality for evaluating nerve root integrity. Recent improvements in MRI techniques have made it an attractive alternative to evaluate nerve root avulsions (preganglionic injuries). We demonstrate the utility of MRI for the evaluation of normal and avulsed spinal nerve roots. We also show the utility of ultrasound in providing useful preoperative evaluation of the postganglionic brachial plexus in patients with NBPP.

    Surgical site infection is a major cause of morbidity after colorectal resections. Despite evidence that preoperative oral antibiotics with mechanical bowel preparation reduce surgical site infection rates, the use of oral antibiotics is decreasing. Currently, the administration of oral antibiotics is controversial and considered ineffective without mechanical bowel preparation. The aim of this study is to examine the use of mechanical bowel preparation and oral antibiotics and their relationship to surgical site infection rates in a colorectal Surgical Care Improvement Project cohort. This retrospective study used Veterans Affairs Surgical Quality Improvement Program preoperative risk and surgical site infection outcome data linked to Veterans Affairs Surgical Care Improvement Project and Pharmacy Benefits Management data. Univariate and multivariable models were performed to identify factors associated with surgical site infection within 30 days of surgery. This study was conducted in 112 Veterans Affairs hospitals. Included were 9940 patients who underwent elective colorectal resections from 2005 to 2009. The primary outcome measured was the incidence of surgical site infection. Patients receiving oral antibiotics had significantly lower surgical site infection rates. Those receiving no bowel preparation had similar surgical site infection rates to those who had mechanical bowel preparation only (18.1% vs 20%). Those receiving oral antibiotics alone had an surgical site infection rate of 8.3%, and those receiving oral antibiotics plus mechanical bowel preparation had a rate of 9.2%. In adjusted analysis, the use of oral antibiotics alone was associated with a 67% decrease in surgical site infection occurrence (OR=0.33, 95% CI 0.21-0.50). Oral antibiotics plus mechanical bowel preparation was associated with a 57% decrease in surgical site infection occurrence (OR=0.43, 95% CI 0.34-0.55).

    The objective of this study was to evaluate the effects of musical intervention on preoperative anxiety and vital signs in patients undergoing day surgery. Studies and systematic meta-analyses have shown inconclusive results of the efficacy of music in reducing preoperative anxiety. We designed a study to provide additional evidence for its use in preoperative nursing care. Randomised, controlled study. Patients (n = 183) aged 18-65 admitted to our outpatient surgery department were randomly assigned to either the experimental group (music delivered by earphones) or control group (no music) for 20 minutes before surgery. Anxiety, measured by the State-Trait Anxiety Inventory, and vital signs were measured before and after the experimental protocol. A total of 172 patients (60 men and 112 women) with a mean age of 40·90 (SD 11·80) completed the study. The largest number (35·7%) was undergoing elective plastic surgery and 76·7% of the total reported previous experience with surgery. Even though there was only a low-moderate level of anxiety at the beginning of the study, both groups showed reduced anxiety and improved vital signs compared with baseline values; however, the intervention group reported significantly lower anxiety [mean change: -5·83 (SD 0·75) vs. -1·72 (SD 0·65), p < 0·001] on the State-Trait Anxiety Inventory compared with the control group. Patients undergoing day surgery may benefit significantly from musical intervention to reduce preoperative anxiety and improve physiological parameters. Finding multimodal approaches to ease discomfort and anxiety from unfamiliar unit surroundings and perceived risks of morbidity (e.g. disfigurement and long-term sequelae) is necessary to reduce preoperative anxiety and subsequent physiological complications. This is especially true in the day surgery setting, where surgical admission times are often subject to change and patients may have to accommodate on short notice or too long a wait that may provoke

    To investigate the possible mechanisms by which cataract surgery aggravates meibomian gland dysfunction (MGD), we evaluated the changes in tear cytokines and ocular surface parameters after cataract surgery according to the preoperative MGD grade. Prospective, observational case series. A total of 50 eyes from 50 patients who underwent cataract surgery were included. Patients were classified into two groups: Group I had no or minimal MGD, and group II had grades 2-4 MGD. Ocular surface parameters were measured, including tear film break-up time, Schirmer I test, ocular surface staining and Ocular Surface Disease Index, and tear cytokine levels were measured. The main outcomes were changes in ocular surface parameters and inflammatory tear cytokine concentrations. In group II, preoperative MGD grade, ocular surface staining, tear film break-up time and Ocular Surface Disease Index were worse, and mean interleukin (IL)-2, IL-6 and TNF-α levels were higher than those of group I. MGD and ocular surface parameters were worsened to a greater degree after surgery in group II than in group I (P < 0.050). In group II, IL-6 and TNF-α levels significantly increased at postoperative 1 month, and there were significant correlations between changes in ocular surface parameters and tear cytokines (IL-2, IL-6 and TNF-α; P < 0.050). The extent to which the MGD grade was aggravated following cataract surgery differed based on preoperative MGD grade. Preoperative MGD and ocular surface status should be carefully evaluated. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

    In a new health care economy, there is an emerging need to understand and quantify predictors of total hip arthroplasty (THA) outcomes. We investigated the association between preoperative radiographic disease (as measured quantitatively by joint space width [JSW]) and patient-reported function, activity, pain, and quality of life after THA. We retrospectively analyzed 146 patients (146 hips) 55 years or younger with a diagnosis of osteoarthritis who underwent cementless THA between January 2009 and December 2010. Preoperative pelvic radiographs were measured by 1 author blinded to clinical outcomes to establish JSW, defined as the shortest distance between the femoral head margin and the superolateral weight-bearing portion of the acetabulum. The JSW value was treated as a continuous variable when applied to statistical modeling. The relationship between the JSW and the improvement of clinical outcome was examined via a general linear modeling approach with adjustments for patients' age, body mass index, and sex. We identified an inverse relationship between preoperative JSW and improvements in functional, activity, pain, and quality of life. We found that, as JSW decreased by 1 mm, the outcome measure improvements were modified Harris Hip Score of 6.3 (p<0.001); SF-12 physical: 2.1 (p=0.027); WOMAC-pain: 4.8 (p=0.01); and UCLA Activity: 0.44 (p=0.02). Our results demonstrate that patients with greater preoperative joint space have less predictable improvement in terms of function, pain relief, and activity. These findings suggest that THA in young patients with a JSW less than 1.5 to 2 mm provides more predictable improvements in pain and functional outcomes. Copyright © 2016 Elsevier Inc.

    Objectives Effective postoperative pain management is crucial in the care of surgical patients. Opioids, which are commonly used in managing postoperative pain, have a potential for tolerance and addiction, along with sedating side effects. Gabapentin’s use as a multimodal analgesic regimen to treat neuropathic pain has been documented as having favorable side effects. This meta-analysis examined the use of preoperative gabapentin and its impact on postoperative opioid consumption. Materials and methods A comprehensive literature search was conducted to identify randomized control trials that evaluated preoperative gabapentin on postoperative opioid consumption. The outcomes of interest were cumulative opioid consumption following the surgery and the incidence of vomiting, somnolence, and nausea. Results A total of 1,793 patients involved in 17 randomized control trials formed the final analysis for this study. Postoperative opioid consumption was reduced when using gabapentin within the initial 24 hours following surgery (standard mean difference −1.35, 95% confidence interval [CI]: −1.96 to −0.73; P<0.001). There was a significant reduction in morphine, fentanyl, and tramadol consumption (P<0.05). While a significant increase in postoperative somnolence incidence was observed (relative risk 1.30, 95% CI: 1.10–1.54, P<0.05), there were no significant effects on postoperative vomiting and nausea. Conclusion The administration of preoperative gabapentin reduced the consumption of opioids during the initial 24 hours following surgery. The reduction in postoperative opioids with preoperative gabapentin increased postoperative somnolence, but no significant differences were observed in nausea and vomiting incidences. The results from this study demonstrate that gabapentin is more beneficial in mastectomy and spinal, abdominal, and thyroid surgeries. Gabapentin is an effective analgesic adjunct, and clinicians should consider its use in multimodal treatment

Preoperative Evaluation Clinic at Mayo Clinic, Rochester, Minnesota. 502 adult surgical patients scheduled for elective surgery. A survey was designed and administered to patients in the preoperative clinic to assess their knowledge of the job descriptions and roles of anesthesiologists. The survey also included questions about information that patients desire before anesthesia and surgery. The survey was distributed to 502 patients, 500 of whom (99%) completed the survey. Seventy-four percent (346/466) of respondents were educated at or above the college level. The majority (377/460; 82%) of patients in this study had adequate or high health literacy levels. Four hundred sixteen of 486 (86%) respondents knew that an anesthesiologist was a doctor specializing in anesthesia. However, the roles of anesthesiologists throughout the hospital system were not well known. Ninety-six of 475 (20%) patients knew that anesthesiologists may work in pain management clinics, 80 of 470 (17%) patients knew that anesthesiologists may work in intensive care units, but only 59 of 472 (13%) patients knew that anesthesiologists may transfuse blood during surgery if needed. Despite the high level of education and health literacy in this group of patients, many were uninformed about the roles of anesthesiologists. Patients expressed interest in receiving a broad range of information during the preoperative visit. An educational booklet was the preferred method to provide this information.

    Pre-operative visiting by theatre nurses is now policy in many hospitals, following an explosion of research studies outlining the benefits to the patient. However, the author could find very little available literature on pre-operative visiting by intensive therapy unit (ITU) nurses, to patients electively admitted to ITU following surgery. The purpose of this project is to explore the need for patient information, outline the aims of an ITU nurse's pre-operative visit, and discuss the timing of the proposed visit, the information to give the patient, the inclusion of the patient's family and the provision of printed literature. Finally, recommendations are made for implementing a pre-operative visiting service by ITU nurses.

    The pre-operative body wash is a strategy for reducing post-operative infection. However, there is a lack of knowledge about its importance. The purpose of the present study was to evaluate the quality of guidelines for the pre-operative body wash using the AGREE instrument--35 guidelines containing instructions for the pre-operative body wash or preparation were included. The AGREE instrument was employed to establish a quality assessment framework that facilitated a comparison of the guidelines. The results were based on the six domains of the AGREE instrument, all of which were found to have low adherence. Descriptive statistics were used to present the assessment score. The AGREE instrument is useful for evaluating the quality of clinical guidelines. The development of evidence-based guidelines must include clinical activities. Further research is required to clarify the pre-operative body wash process and how it should be performed to reduce post-operative infection.

    Patient education is a major concern for perioperative nurses in an ambulatory surgery setting. It has proven difficult to develop formal preoperative teaching programs in this environment, but research has shown that preoperative education can improve patient outcomes and satisfaction with the surgical experience. Typical patient education consists of pamphlets that are given to the patient before surgery and verbal instructions from the physicians and nurses on the day of surgery. Ideally, preoperative patient education should begin in the surgeon's office, continue through preadmission testing, and be completed at admission. Having a well-designed preoperative education program enables perioperative nurses in ambulatory surgery centers to provide a thoughtful approach to perioperative teaching in a limited time.

    Neonates undergoing noncardiac surgery are at risk for adverse outcomes. Preoperative anemia is a strong independent risk factor for postoperative mortality in adults. To our knowledge, this association has not been investigated in the neonatal population. To assess the association between preoperative anemia and postoperative mortality in neonates undergoing noncardiac surgery in a large sample of US hospitals. Using data from the 2012 and 2013 pediatric databases of the American College of Surgeons National Surgical Quality Improvement Program, we conducted a retrospective study of neonates undergoing noncardiac surgery. Analysis of the data took place between June 2015 and December 2015. All neonates (0-30 days old) with a recorded preoperative hematocrit value were included. Anemia defined as hematocrit level of less than 40%. Receiver operating characteristics analysis was used to assess the association between preoperative hematocrit and mortality, and the Youden J Index was used to determine the specific hematocrit cutoff point to define anemia in the neonatal population. Demographic and postoperative outcomes variables were compared between anemic and nonanemic neonates. Univariate and multivariable logistic regression analyses were used to determine factors associated with postoperative neonatal mortality. An external validation was performed using the 2014 American College of Surgeons National Surgical Quality Improvement Program database. Neonates accounted for 2764 children (6%) in the 2012-2013 American College of Surgeons National Surgical Quality Improvement Program databases. Neonates inlcuded in the study were predominately male (64.5%), white (66.3%), and term (69.9% greater than 36 weeks' gestation) and weighed more than 2 kg (85.0%). Postoperative in-hospital mortality was 3.4% in neonates and 0.6% in all age groups (0-18 years). A preoperative hematocrit level of less than 40% was the optimal cutoff (Youden) to predict in-hospital mortality

    Preoperative planning enables an assessment of the size of the implants needed before total hip replacement. Eggli and Müller demonstrated the reproduciblity of preoperative planning but did not evaluate its contribution to reducing limb length discrepancy. As femur lateralization and the position of the prosthetic center of rotation affect joint mechanics, it would be useful to assess their contribution to the efficacy of preoperative planning. We reviewed the files of 57 patients who underwent total hip arthroplasty for primary joint degeneration or necrosis limited to one hip. The healthy hip served as a control. The surgical plan was elaborated from the preoperative pelvis x-rays (AP and lateral views) and anatomic measurements on films obtained three months postoperatively. In 49 cases, preoperative planning predicted a restoration of the normal anatomy of the operated hip (center of rotation, femur lateralization, length of the operated limb). This objective was achieved in only 22.5% of the cases. Femur lateralization was the most difficult objective to achieve (59.2%). Equal limb length and good position of the center of rotation was achieved in 70% of the cases. For eight patients (14%) preoperative planning was not satisfactory, the implant offset not being adapted to the patient's anatomy. There are limits to preoperative planning, particularly for restitution of adequate femur lateralization. This difficulty appears to be related to three factors: inadequate adaptation of the implant to hip anatomy (14% of the cases in our experience), stiff rotation in degenerative hips inhibiting proper assessment of the length of the femoral neck, and relative imprecision of operative evaluation of femoral anteversion affecting femur lateralization and the level of the femoral cut. Although imperfect, preoperative planning is, in our opinion, essential before total hip arthroplasty in order to avoid major positioning errors and operative difficulties.

    2014-01-01

    Introduction: We sought to determine whether the use of preoperative antibiotics is effective in reducing postoperative wound infections and urinary tract infections (UTI) in hypospadias repair. Methods: We retrospectively reviewed all hypospadias repairs performed at the Montreal Children’s Hospital between March 2009 and September 2012. All types of primary hypospadias repairs and redo cases were included. Patients with no adequate follow-up or with missing records of antibiotics were excluded. Preoperative antibiotics were given in the form of cefazolin (50 mg/kg intravenously) when appropriate. Postoperative oral antibiotics were administered as decided by the pediatric urologist. Primary outcomes included postoperative wound infection and UTI. Secondary outcomes included the need for reoperation of hypospadias due to urethrocutaneous fistula, meatal stenosis, urethral stricture and wound dehiscence. Results: In total, 157 cases of hypospadias repair were reviewed; of these 7 were excluded due to lack of follow-up. Of the remaining 150 patients, 62 received preoperative antibiotics and 88 did not. The groups were well-matched for age, hypospadias characteristics, type of repair and repair of curvature. The group that received preoperative antibiotics had a significantly higher number of stented cases (82% vs. 52% of the non-preoperative antibiotic group). Two cases of wound infection were reported (1 in the pre-operative antibiotic group and 1 in the non-preoperative antibiotic group). There was no symptomatic UTI or culture-demonstrated UTI in either group. Moreover, there was no statistically significant difference between the 2 groups in terms of primary outcomes. The complication rate was 11% (17/150 repairs) and all patients needed reoperation. This study’s important limitations include the rarity of studied end points combined with the small sample and the retrospective nature of our study. Conclusion: Our findings do not support the routine use of

    Preoperative anemia impacts a significant portion of breast reconstruction patients, though this does not appear to affect surgical outcomes. The impact of anemia on postoperative physical and mental health, however, is unknown. This study aimed to prospectively evaluate the role of preoperative anemia in recovery after autologous reconstruction. From 2005 to 2010, we prospectively assessed autologous breast reconstruction patients with satisfaction surveys, strength and functional tests, and the short form 36 (SF36). Data was collected preoperatively and at early (<90d), intermediate (90-365d), and late (>365d) follow-up. We stratified patients by presence or lack of preoperative anemia (hemoglobin<12 g/dL). Of 399 patients undergoing reconstruction, 179 enrolled in the study. Anemic patients (n = 31, 17%) had higher rates of preoperative chemotherapy (p = 0.02) and lower rates of radiation (p = 0.001). Preoperatively, anemic patients reported worse physical (p < 0.001), mental (p = 0.003) and overall health (p = 0.0003). These scores worsened postoperatively for anemic and nonanemic patients, though anemic patients had lower average scores in all SF36 categories. This was significant only for early follow-up physical health (p = 0.02). Change in SF36 scores and objective physical exam assessments did not differ between the two cohorts. Though preoperative anemia may not impact surgical outcomes, it adversely impacts the recovery of breast reconstruction patients. Subjective physical health differences were significant in early follow-up, though this did not translate to differences in mental health or satisfaction. We advocate for preoperative optimization of hemoglobin to enhance the early recovery potential of breast reconstruction patients.

    Patients' knowledge deficits concerning anesthesia and the anesthesiologist's role in their care may contribute to anxiety. The objective of this study was to develop anesthesia patient education materials that would help improve patient's satisfaction regarding their knowledge of the perioperative process and decrease anxiety in a community hospital with a large Spanish-speaking population. A survey (Survey A) in English and Spanish was administered to all adult anesthesiology preoperative clinic patients during a 4-week period. The data were analyzed and then a patient education handout was developed in both English and Spanish to assist with our patients' major concerns. A second survey (Survey B) was administered that was completed after the education handout had been put into use at the clinic. The survey asked for basic demographic information and included questions on satisfaction with regard to understanding of anesthesia as well as worries regarding surgery and pain. In the patients who received the handout, statistically significant improvement was found in the questions that asked about satisfaction with regard to understanding of type of anesthesia, options for pain control, what patients are supposed to do on the day of surgery, and the amount of information given with regard to anesthetic plan. There was no difference in anxiety related to surgery in patients who received the educational handout compared to those patients who did not. Patient education handouts improved patient's satisfaction regarding their knowledge of the perioperative process but did not reduce anxiety related to surgery.

    The aim of the study was to evaluate the effects of preoperative fasting and fluid limitation in patients undergoing laparoscopic cholecystectomy. Although traditional long-term fasting is not recommended in current preoperative guidelines, this is still a common intervention. Visual analogue scale was used to assess hunger, thirst, sleepiness, exhaustion, nausea and pain; State and Trait Anxiety Inventory was used to assess the preoperative anxiety of 99 patients undergoing elective laparoscopic cholecystectomy. Mean time of preoperative fasting and fluid limitation were, respectively, 14.70 ± 3.14 and 11.25 ± 3.74 h. Preoperatively, 58.60% of the patients experienced moderate anxiety. Patients fasting 12 h or longer had higher hunger, thirst, nausea and pain scores. The mean trait anxiety score of patients fasting 12 h or longer was statistically significantly higher. Receiving nothing by mouth after midnight preoperatively is a persisted intervention and results in discomfort of patients. Clinical protocols should be revised and nurses should be trained in current fasting protocols. © 2014 Wiley Publishing Asia Pty Ltd.

    Preoperative planning is an essential prerequisite for the success of orthopaedic procedures. Traditionally, the exercise has involved the written down, step by step "blueprint" of the surgical procedure. Preoperative planning of the technical aspects of the orthopaedic procedure has been performed on hardcopy radiographs using various methods such as copying the radiographic image on tracing papers to practice the planned interventions. This method has become less practical due to variability in radiographic magnification and increasing implementation of digital imaging systems. Advances in technology along with recognition of the importance of surgical safety protocols resulted in widespread changes in orthopaedic preoperative planning approaches. Nowadays, perioperative "briefings" have gained particular importance and novel planning methods have started to integrate into orthopaedic practice. These methods include using software that enables surgeons to perform preoperative planning on digital radiographs and to construct 3D digital models or prototypes of various orthopaedic pathologies from a patient's CT scans to practice preoperatively. Evidence-to-date suggests that preoperative planning and briefings are effective means of favorably influencing the outcomes of orthopaedic procedures.

    We describe a series of 14 surgical blister aneurysm (BA) patients and compare outcomes in those with known cerebral BA to those lacking preoperative BA diagnosis/recognition. BA are broad, fragile, pathologic dilatations of the intracranial arteries. They have a low prevalence but are associated with substantially higher surgical morbidity and mortality rates than saccular aneurysms. A confirmed, preoperative BA diagnosis can alter operative management and technique. We performed a retrospective review of prospectively collected data on aneurysm patients undergoing surgery at a major academic institution. All patients from 1990 to 2011 with a postoperative BA diagnosis were included. Chart reviews were performed to identify patients with preoperative BA diagnoses and collect descriptive data. We identified 14 patients, 12 of whom presented with subarachnoid hemorrhage. The age of the cohort (mean ± standard deviation: 41.8 ± 13.9 years) was lower than that generally reported for saccular aneurysm populations. Preoperatively diagnosed BA had an intraoperative rupture (IOR) rate of 28.6% (2/7) compared to a 57.1% (4/7) rate in the undiagnosed patients. The mortality rate in the preoperatively diagnosed cohort was 14.3% (1/7) while that of the undiagnosed group was 42.8% (3/7). BA remain a diagnostic and treatment challenge with morbidity and mortality rates exceeding those of saccular aneurysms. Preoperative BA diagnosis may decrease IOR and mortality rates and improve patient outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    During surgery, peripheral nerves are often seen to follow unpredictable paths because of previous surgeries and/or compression caused by a tumor. Iatrogenic nerve injury is a serious complication that must be avoided, and preoperative evaluation of nerve paths is important for preventing it. In this study, transcutaneous electrical nerve stimulation (TENS) was used for an in-depth analysis of peripheral nerve paths. This study included 27 patients who underwent the TENS procedure to evaluate the peripheral nerve path (17 males and 10 females; mean age: 59.9 years, range: 18-83 years) of each patient preoperatively. An electrode pen coupled to an electrical nerve stimulator was used for superficial nerve mapping. The TENS procedure was performed on patients' major peripheral nerves that passed close to the surgical field of tumor resection or trauma surgery, and intraoperative damage to those nerves was apprehensive. The paths of the target nerve were detected in most patients preoperatively. The nerve paths of 26 patients were precisely under the markings drawn preoperatively. The nerve path of one patient substantially differed from the preoperative markings with numbness at the surgical region. During surgery, the nerve paths could be accurately mapped preoperatively using the TENS procedure as confirmed by direct visualization of the nerve. This stimulation device is easy to use and offers highly accurate mapping of nerves for surgical planning without major complications. The authors conclude that TENS is a useful tool for noninvasive nerve localization and makes tumor resection a safe and smooth procedure.

    Despite the availability of guidelines for preoperative cardiology consultations, their efficacy in real clinical practice remains unknown. Furthermore, there are concerns that overused cardiology consultations can lead to unnecessary investigations, prolonged hospital stays, and even cancellation of necessary surgery. In this retrospective study, we investigated: (i) the potential impact of the American Heart Association/American College of Cardiology algorithm and (ii) the potential of this algorithm for preventing unnecessary evaluation. We examined the cardiology consultation requests for 712 patients scheduled for elective surgery. Our analysis included: (i) patient characteristics, (ii) abnormalities revealed by the consultant, (iii) impact of these abnormalities on clinical decision making and therapy modification. The most common reason for consultation was 'pre-operative evaluation' (80.9%). Although our cardiologists revealed an abnormality in 67.8% and recommended further work up in 58.7% of our patients, they contributed to the clinical course in only 36.9%. Moreover, when the algorithm was applied to 'routine pre-operative evaluation' requests lacking a specific question, only 7.6% of these consultation requests required further investigation. Preoperative cardiology consultation seems to be overused. Although the fear of missing important issues leads surgeons to use a decreased threshold for pre-operative consultation requests, such a non-specific manner of pre-operative consultation request causes unnecessary investigations and decreased cost-effectiveness. Furthermore, the detection of any clinical abnormality by cardiologists surprisingly adds little to clinical decision making.

    There are more than 29 million people in the United States with diabetes; it is estimated that by 2050, one in 3 individuals will have the disease. At least 50% of patients with diabetes are expected to undergo surgery in their lifetime. Complications from uncontrolled diabetes can impact multiple organ systems and affect perioperative risk. In this review, the authors discuss principles in diabetes management that will assist the perioperative clinician in caring for patients with diabetes.

    Background. The study aims to verify if the time of preoperative stabilization (≤24 or >24 hours) could be predictive for the severity of clinical condition among patients affected by congenital diaphragmatic hernia. Methods. 55 of the 73 patients enrolled in the study achieved presurgical stabilization and underwent surgical correction. Respiratory and hemodynamic indexes, postnatal scores, the need for advanced respiratory support, the length of HFOV, tracheal intubation, PICU, and hospital stay were compared between patients reaching stabilization in ≤24 or >24 hours. Results. Both groups had a 100% survival rate. Neonates stabilized in ≤24 hours are more regular in the postoperative period and had an easier intensive care path; those taking >24 hours showed more complications and their care path was longer and more complex. Conclusions. The length of preoperative stabilization does not affect mortality, but is a valid parameter to identify difficulties in survivors' clinical pathway. PMID:22262976

    Background Patients with obstructive jaundice have various pathophysiological changes that affect the liver, kidney, heart, and the immune system. There is considerable controversy as to whether temporary relief of biliary obstruction prior to major definitive surgery (pre-operative biliary drainage) is of any benefit to the patient. Objectives To assess the benefits and harms of pre-operative biliary drainage versus no pre-operative biliary drainage (direct surgery) in patients with obstructive jaundice (irrespective of a benign or malignant cause). Search methods We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Clinical Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2012. Selection criteria We included all randomised clinical trials comparing biliary drainage followed by surgery versus direct surgery, performed for obstructive jaundice, irrespective of the sample size, language, and publication status. Data collection and analysis Two authors independently assessed trials for inclusion and extracted data. We calculated the risk ratio (RR), rate ratio (RaR), or mean difference (MD) with 95% confidence intervals (CI) based on the available patient analyses. We assessed the risk of bias (systematic overestimation of benefit or systematic underestimation of harm) with components of the Cochrane risk of bias tool. We assessed the risk of play of chance (random errors) with trial sequential analysis. Main results We included six trials with 520 patients comparing pre-operative biliary drainage (265 patients) versus no pre-operative biliary drainage (255 patients). Four trials used percutaneous transhepatic biliary drainage and two trials used endoscopic sphincterotomy and stenting as the method of pre-operative biliary drainage. The risk of bias was high in all trials. The proportion of patients with malignant obstruction varied between 60

    Postoperative pulmonary complications (PPCs) have an impact on the recovery of adults after surgery. It is therefore important to establish whether preoperative respiratory rehabilitation can decrease the risk of PPCs and to identify adults who might benefit from respiratory rehabilitation. Our primary objective was to assess the effectiveness of preoperative inspiratory muscle training (IMT) on PPCs in adults undergoing cardiac or major abdominal surgery. We looked at all-cause mortality and adverse events. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 10), MEDLINE (1966 to October 2014), EMBASE (1980 to October 2014), CINAHL (1982 to October 2014), LILACS (1982 to October 2014), and ISI Web of Science (1985 to October 2014). We did not impose any language restrictions. We included randomized controlled trials that compared preoperative IMT and usual preoperative care for adults undergoing cardiac or major abdominal surgery. Two or more review authors independently identified studies, assessed trial quality, and extracted data. We extracted the following information: study characteristics, participant characteristics, intervention details, and outcome measures. We contacted study authors for additional information in order to identify any unpublished data. We included 12 trials with 695 participants; five trials included participants awaiting elective cardiac surgery and seven trials included participants awaiting elective major abdominal surgery. All trials contained at least one domain judged to be at high or unclear risk of bias. Of greatest concern was the risk of bias associated with inadequate blinding, as it was impossible to blind participants due to the nature of the study designs. We could pool postoperative atelectasis in seven trials (443 participants) and postoperative pneumonia in 11 trials (675 participants) in a meta-analysis. Preoperative IMT was associated with a reduction of postoperative atelectasis and

    Preoperative psychological screening of bariatric surgery candidates has become routine, and a significant proportion of patients have their surgery deferred as a consequence. If psychological testing is being used as a form of preoperative triage, both patients and surgeons are entitled to know whether there is sufficient evidence to justify its use in this way. We define the argument for psychological screening as consisting of four premises (p1-p4) and a conclusion (C) as follows: (p1) A significant minority of obese patients will not be successful in losing weight following bariatric surgery-the "failure" group; (p2) A significant minority of patients will exhibit abnormal psychological profiles during preoperative testing; (p3) The majority of individuals referred to in (p2) will be found in group (p1) i.e., abnormal psychological profiles identified preoperatively predict less favorable weight loss outcomes postoperatively; (p4) Identifying patients with adverse psychological profiles preoperatively would allow either exclusion of those at high risk of failure or provide a more secure rationale for targeted pre- and postoperative support; (C) Psychological screening should be part of the routine preoperative assessment for patients undergoing obesity surgery. We reviewed the literature to find evidence to support the premises and show that (p1) can be justified but that (p2) is problematic and can only be accepted in a heavily qualified version. We find no evidence for (p3) and since (p4) and (C) are predicated on (p3), the argument clearly fails. There is no evidence to suggest that preoperative psychological screening can predict postoperative outcomes and no justification for using such testing as a means of discriminating between candidates presenting themselves for bariatric surgery.

    Previous studies have suggested that, to improve refractive predictability in hyperopic LASIK treatments, preoperative cycloplegic or manifest refraction, or a combination of both, could be used in the laser nomogram. We set out to investigate (1) the prevalence of a high difference between manifest and cycloplegic spherical equivalent in hyperopic eyes preoperatively, and (2) the related predictability of postoperative keratometry. Retrospective cross-sectional data analysis of consecutive treated 186 eyes from 186 consecutive hyperopic patients (mean age 42 [±12] years) were analyzed. Excimer ablation for all eyes was performed using a mechanical microkeratome (SBK, Moria, France) and an Allegretto excimer laser platform. Two groups were defined according to the difference between manifest and cycloplegic spherical equivalent which was defined as ≥1.00 diopter (D); the data was analyzed according to refractive outcome in terms of refractive predictability, efficacy, and safety. In 24 eyes (13 %), a preoperative difference of ≥1.00D between manifest spherical equivalent and cycloplegic spherical equivalent (= MCD) occurred. With increasing preoperative MCD, the postoperative achieved spherical equivalent showed hyperopic regression after 3 months. There was no statistically significant effect of age (accommodation) or optical zone size on the achieved spherical equivalent. A difference of ≥1.00D occurs in about 13 % of hyperopia cases. We suggest that hyperopic correction should be based on the manifest spherical equivalent in eyes with preoperative MCD <1.00D. If the preoperative MCD is ≥1.00D, treatment may produce manifest undercorrection, and therefore we advise that the patient should be warrned about lower predictability, and suggest basing conclusions on the arithmetic mean calculated from the preoperative manifest and cycloplegic spheres.

    Perioperative care demands consideration of individual treatment goals. We evaluated the attitudes of medical staff towards a short standardized advance directive (SSAD) as a means of improving patient-orientated care at the transition from operating theater to general or intensive care wards. Multicenter anonymized standardized multiple-choice questionnaire among physicians and nurses from various operative and anesthesiology departments. Questions addressing demographic parameters and attitudes towards advance directives in acute care settings (eleven 4‑stepped Likert items). Univariate analysis of group comparisons using the chi-square and Kruskal-Wallis rank-sum test. Multivariable analysis of significant differences employing ordinal logistic regression. The overall return rate was 28.2 % (169 questionnaires). Of these, 19.5 % said that existing advance directives were regularly reassessed preoperatively. SSAD was expected to provide improved emergency care by 82.3 and 76.6 % thought that it would help to better focus intensive care resources according to patients' needs. Our study shows the dilemma of insufficiently structured directives for changing treatment goals as well as a high number of legal procedures to obtain proxy decisions due to missing out-patient advance health planning. From a medical staff perspective there is strong support for the concept of SSAD based on medical, ethical, economic and organizational reasons.

    With the purpose of decreasing the existing variability in the criteria of preoperative evaluation and facilitating the clinical decision-making process, our hospital has a protocol of preoperative tests to use with ASA I and ASA II patients. The aim of the study was to calculate the economic impact caused by clinicians' non-adherence to the protocol for the anaesthesiological evaluation of ASA 1 and ASA II patients. A retrospective study of costs with a random sample of 353 patients that were seen in the consultation for Anesthesiology over a period of one year. Aspects related to the costs, patient's profiles and specialties were analysed, according to the degree of fulfillment of the protocol. The lack of adherence to the the protocol was 70%. 130 chest X-rays and 218 ECG were performed without indication. This generated an excess costs of 34 € per patient. Taking into account the expenses of both tests and the attended population undergoing ambulatory surgery during the one-year period, an excess spending for the hospital of between 69.164 € and 83.312 € was estimated. Clinical variability should be reduced and the creation of synergies between the different departments should be enhanced in order to adjust the request for unnecessary complementary tests to decrease health care and to improve the quality of patient care.

    Background Perioperative hemorrhage negatively impacts patient outcomes and results in substantial health care resource consumption. Plasma transfusions are frequently administered to address abnormal preoperative coagulation tests, with the hope of mitigating bleeding complications. This study aimed to evaluate the associations between preoperative plasma transfusion and bleeding complications in patients with elevated international normalized ratios undergoing noncardiac surgery. Methods An observational comparative effectiveness research study evaluating a consecutive sample of adult patients undergoing noncardiac surgery (N=14,743) with preoperative international normalized ratios ≥ 1.5 between January 1, 2008, and December 31, 2011. Among the patients, 1,234 (8.4%) had an international normalized ratio ≥ 1.5 and were included in this investigation. Exposure of interest was transfusion of preoperative plasma for an elevated international normalized ratio. Primary outcome was World Health Organization grade 3 bleeding in the early perioperative period. Secondary outcomes included blood loss, reoperation for bleeding, and additional patient-important outcomes including death and lengths of stay. Hypotheses were tested with univariate and propensity-matched analyses. Multiple sensitivity analyses were performed to further evaluate the robustness of study findings. Findings Of 1,234 study participants, 139 (11.3%) received a preoperative plasma transfusion. Those who received plasma had a higher rate of perioperative (52.5% vs 32.0%; P < .0001) and intraoperative (40.3% vs 24.5%; P < .0001) red blood cell transfusion, as well as an increased rate of reoperation for bleeding (11.5% vs 4.5%; P = .0005). The increased rate of perioperative red blood cell transfusion stayed in the propensity-matched analyses (OR, 1.75 [95% CI, 1.09–2.81]; P= .0210). Results from multiple sensitivity analyses were qualitatively similar. Interpretation Preoperative plasma

    Context: Frequent incidence of early postoperative memory impairment (POMI) after cardiac surgery remains a concern because of associated morbidity, impaired quality of life, and increased health care cost. Aim: To assess the effect of preoperative statin therapy on POMI in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. Setting and Design: Prospective observational study in a tertiary level hospital. Methods: Sixty patients aged 45–65 years undergoing OPCAB surgery were allocated into two groups of 30 each. Group A patients were receiving statin and Group B patients were not receiving statins. All patients underwent memory function assessment preoperatively after admission to hospital and on the 6th postoperative day using postgraduate institute memory scale. Statistical Analysis: Appropriate tests were applied with SPSS 20 to compare both groups. The value P < 0.05 was considered statistically significant. Multiple regression analysis was performed with confounding factors to determine the effect on memory impairment. Results: Patients in Group A showed significant postoperative deterioration in 6 of the 10 functions and in Group B showed deterioration in 9 of 10 functions tested compared to preoperative scores. Intergroup comparison detected less POMI in Group A compared to Group B and was statistically significant in 8 memory functions. Multiple regression analysis detected statin as an independent factor in preventing memory impairment. Conclusions: Preoperative statin therapy attenuates the early POMI in patients undergoing OPCAB. Future long-term studies will define the efficacy of statin on POMI. PMID:26750672

    A patient with thalassemia minor and idiopathic scoliosis was scheduled for posterior vertebral arthrodesis. The diagnosis of thalassemia minor was made during the preoperative assessment. Preoperative blood cell count displayed the following data: red blood count 5.4 x 106/microL, haemoglobin 11.6 g/dL and hematocrit 36.9%. As corrective surgery for scoliosis is associated with major blood loss, the patient was scheduled for preoperative treatment with human recombinant erythropoietin (rHuEPO), autologous blood donation, intraoperative blood cell salvage and administration of tranexamic acid. The use of rHuEPO was intended to increase hemoglobin (12.1 g/dL) levels at the moment of surgery following the donation of 2 autologous blood units. 1000 mL of salvaged blood were processed. The output line of the blood cell salvage machine did not show any sign of increased red cell haemolysis. The postoperative course was uneventful and the patient was discharged from the postoperative intensive care unit on day 7 after surgery with no allogenic blood transfusion. No references detailing the use of rHuEPO and autologous blood donation preoperatively in patients with thalassemia minor and only one case report discussed the utility of intraoperative blood cell salvage in a patient with thalassemia intermedia. Although further experience is needed, this case report suggests that even for patients with thalassemia minor, methods focused on allogenic blood salvage can be used safely.

Single-blind randomized controlled pilot study. Gelderse Vallei Hospital Ede, the Netherlands. Twenty high-risk patients undergoing elective abdominal aortic aneurysm surgery were randomly assigned to receive preoperative inspiratory muscle training or usual care. Effectiveness outcome variables were atelectasis, inspiratory muscle strength and vital capacity, and feasibility outcome variables were adverse effects and patient satisfaction with inspiratory muscle training. Despite randomization, patients in the intervention group were significantly older than the patients in the control group (70 +/- 6 years versus 59 +/- 6 years, respectively; P = 0.001). Eight patients in the control group and three in the intervention group developed atelectasis (P = 0.07). The median duration of atelectasis was 0 days in the intervention group and 1.5 days in the control group (P = 0.07). No adverse effects of preoperative inspiratory muscle training were observed and patients considered that inspiratory muscle training was a good preparation for surgery. Mean postoperative inspiratory pressure was 10% higher in the intervention group. Preoperative inspiratory muscle training is well tolerated and appreciated and seems to reduce the incidence of atelectasis in patients scheduled for elective abdominal aortic aneurysm surgery.

    The objective of this study was to determine the association between preoperative nutritional status and postoperative outcomes in children undergoing surgery for congenital heart defects (CHD). Seventy-one patients with CHD were enrolled in a prospective, 2-center cohort study. We adjusted for baseline risk differences using a standardized risk adjustment score for surgery for CHD. We assigned a World Health Organization z score for each subject's preoperative triceps skin-fold measurement, an assessment of total body fat mass. We obtained preoperative plasma concentrations of markers of nutritional status (prealbumin, albumin) and myocardial stress (B-type natriuretic peptide [BNP]). Associations between indices of preoperative nutritional status and clinical outcomes were sought. Subjects had a median (interquartile range [IQR]) age of 10.2 (33) months. In the University of California at San Francisco (UCSF) cohort, duration of mechanical ventilation (median, 19 hours; IQR, 29 hours), length of intensive care unit stay (median, 5 days; IQR 5 days), duration of any continuous inotropic infusion (median, 66 hours; IQR 72 hours), and preoperative BNP levels (median, 30 pg/mL; IQR, 75 pg/mL) were associated with a lower preoperative triceps skin-fold z score (P < .05). Longer duration of any continuous inotropic infusion and higher preoperative BNP levels were also associated with lower preoperative prealbumin (12.1 ± 0.5 mg/dL) and albumin (3.2 ± 0.1; P < .05) levels. Lower total body fat mass and acute and chronic malnourishment are associated with worse clinical outcomes in children undergoing surgery for CHD at UCSF, a resource-abundant institution. There is an inverse correlation between total body fat mass and BNP levels. Duration of inotropic support and BNP increase concomitantly as measures of nutritional status decrease, supporting the hypothesis that malnourishment is associated with decreased myocardial function.

    Preoperative anxiety, as an emotional reaction, is common among patients undergoing surgery. The purpose of this study was to examine the effect of acupressure on preoperative anxiety before abdominal surgery. The 70 subjects of this clinical trial were randomly assigned into the acupressure group (n=35), which received acupressure at the true points, or the placebo group (n=35), which received acupressure at sham (false) points. Preoperative anxiety and vital signs before and after the intervention were measured in both groups. The findings demonstrated a reduction in the level of preoperative anxiety for both groups (P<.001). Furthermore, they showed a statistically significant difference between the mean of vital signs before and after the intervention in the acupressure group (P<.001) and only statistically significant results for cardiovascular (P=.016) and respiratory rates (P=.007) in the placebo group. Overall, findings revealed that acupressure at true points (third eye and Shen men) can reduce higher preoperative anxiety of patients before abdominal surgery and that it has had a more clinically beneficial effect than sham points.

    At the 2012 American Society of Clinical Oncology (ASCO) Annual Meeting, two studies of preoperative systemic therapy for localized prostate cancer garnered significant attention. In the first, investigators evaluated various permutations of conventional hormonal therapies prior to prostatectomy, with detailed biomarker studies focused on tissue androgens. In the second, investigators assessed the novel CYP17 lyase inhibitor abiraterone prior to prostatectomy. Both studies provide a wealth of biological information, but the question remains - will preoperative systemic therapy ultimately be incorporated into clinical algorithms for prostate cancer? Herein, the existing literature for both preoperative hormonal and chemotherapeutic approaches is reviewed. We performed a MEDLINE search of published prospective and retrospective clinical studies assessing preoperative systemic therapy for prostate cancer from 1982 onwards, revealing a total of 75 publications meeting these criteria. Of these, 55 possessed a number of patients (i.e., greater than 10) deemed worth of the current analysis. Beyond outlining these datasets, we discuss the relevance of clinical and pathologic endpoints in assessing preoperative therapy. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    This study focuses on the impact of preoperative narcotic medication use on outcomes of surgical treatment of migraine headaches. A retrospective comparative review was conducted with patients undergoing migraine surgery. Data gathered included demographic information, baseline migraine headache characteristics, migraine surgery sites, postoperative migraine headache characteristics 1 year or more following surgery, and preoperative migraine medication use. Patients were grouped based on preoperative narcotic medication use. The narcotic users were subdivided into low and high narcotic user groups. Preoperative migraine characteristics were comparable between groups and the outcomes of migraine surgery were compared between the groups. Outcomes in 90 narcotic users were compared with those for 112 patients not using narcotic medications preoperatively. Narcotic users showed statistically significantly less reduction in frequency, severity, and duration of migraine headaches after surgery. Narcotic users had clinical improvement in 66.7 percent of patients and elimination in 18.9 percent versus 86.6 and 36.6 percent, respectively, in the nonnarcotic group. The group that consumed narcotics had significantly lower rates of improvement in all migraine indices. Previous studies have discouraged the routine use of narcotic medications in the management of migraine medications. The authors' study demonstrates that narcotic medication use before migraine headache surgery may predispose patients to worse outcomes postoperatively. Because pain cannot be objectively documented, the question remains of whether this failure to improve the pain was indeed a suboptimal response to surgery or the need for narcotic substances.

    Patients scheduled for surgery at the Omaha VA Medical Center were evaluated preoperatively via telemedicine. Following the examination, patients filled out a 15 item, 5 point Likert scale questionnaire regarding their opinion of preoperative evaluation in a VTC format. Evaluations were performed under the direction of nationally recognized guidelines and recommendations of experts in the field of perioperative medicine and were overseen by a staff anesthesiologist from the Omaha VA Medical Center. No significant difficulties were encountered by the patient or the evaluator regarding the quality of the audio/visual capabilities of the VTC link and its ability to facilitate preoperative evaluation. 87.5% of patients felt that virtual evaluation would save them travel time; 87.5% felt virtual evaluation could save them money; 7.3% felt uncomfortable using the VTC link; 12.2% felt the virtual evaluation took longer than expected; 70.7% preferred to be evaluated via VTC link; 21.9% were undecided; 9.7% felt they would rather be evaluated face-to-face with 26.8% undecided; 85.0% felt that teleconsultation was as good as being seen at the Omaha surgical evaluation unit; 7.5% were undecided. Our study has shown that effective preoperative evaluation can be performed using a virtual preoperative evaluation clinic; patients are receptive to the VTC format and, in the majority of cases, prefer it to face-to-face evaluation.

  4. Preoperative antiseptic skin preparations and reducing SSI.

    PubMed

    Al Maqbali, Mohammed Abdullah

    Surgical site infection (SSI) can affect the quality of care and increase the morbidity and mortality rate in after-surgical procedure. The use of an antiseptic skin preparation agent before the procedure can reduce the pathogens in the skin surface around the incision. Indicating the type of skin antiseptic preparation could prevent the infection and contamination of the wound. The most commonly used types of skin preparations are chlorhexidine and povidone iodine. However, the antiseptic solutions of both agents are strengthened with alcohol to prevent postoperative wound infection. The aim of this paper is to identify the best antiseptic agent in terms of skin preparation by evaluating the evidence in the literature. The factors associated with choosing the antiseptic skin agent, such as patients' allergies, skin condition and environmental risk, are also taken into account. This review suggests that cholorhexdine with alcohol may be the most effective in terms of reducing SSI.

    To develop accurate preoperative risk prediction models for multiple adverse postoperative outcomes applicable to a broad surgical population using a parsimonious common set of risk variables and outcomes. Currently, preoperative assessment of surgical risk is largely based on subjective clinician experience. We propose a paradigm shift from the current postoperative risk adjustment for cross-hospital comparison to patient-centered quantitative risk assessment during the preoperative evaluation. We identify the most common and important predictor variables of postoperative mortality, overall morbidity, and 6 complication clusters from previously published prediction analyses that used forward selection stepwise logistic regression. We then refit the prediction models using only the 8 most common and important predictor variables, and compare the discrimination and calibration of these models to the original full-variable models using the c-index, Hosmer-Lemeshow analysis, and Brier scores. Accurate risk models for 30-day outcomes of mortality, overall morbidity, and 6 clusters of complications were developed using a set of 8 preoperative risk variables. C-indexes of the 8 variable models are between 97.9% and 99.2% of those of the full models containing up to 28 variables, indicating excellent discrimination using fewer predictor variables. Hosmer-Lemeshow analyses showed observed to expected event rates to be nearly identical between parsimonious models and full models, both showing good calibration. Accurate preoperative risk assessment of postoperative mortality, overall morbidity, and 6 complication clusters in a broad surgical population can be achieved with as few as 8 preoperative predictor variables, improving feasibility of routine preoperative risk assessment for surgical patients.

    With the universal adoption of antibiotic prophylaxis prior to prostate biopsy, the current risk of post-biopsy infection (including sepsis) is <2%. Preoperative prophylactic antibiotic regimens can vary, and although fluoroquinolones have emerged as the standard of care, there is no universally agreed upon preoperative antibiotic regimen. Recently, an increase in the proportion of postoperative infections caused by fluoroquinolone-resistant Escherichia coli (as well as other Enterobacteriaceae) has led to the exploration of simple, practical, and cost-effective methods to minimize this postoperative infection risk. We performed a prospective, nonrandomized, controlled study of preoperative rectal cultures to screen for rectal colonization with fluoroquinolone-resistant bacteria using ciprofloxacin-supplemented MacConkey agar culture media. To evaluate the feasibility and practicality of this test, one provider used the results of rectal swab cultures collected during the preoperative outpatient evaluation to adjust each patient’s preoperative antibiotic prophylaxis when fluoroquinolone-resistant enteric bacteria were detected, whereas two other providers continued usual preoperative care and empiric antimicrobial prophylaxis. Rectal colonization with fluoroquinolone-resistant bacteria was detected in 19/152 (12.5%) of patients. In our intention-to-treat analysis (N=268), the rate of post-biopsy sepsis was 3.6% lower in the group that was screened for rectal colonization with fluoroquinolone-resistant bacteria prior to transrectal prostate biopsy. The observed risk reduction in the rectal screening group trended toward, but did not achieve, statistical significance. We suggest that preoperative screening for rectal colonization with fluoroquinolone-resistant enteric bacteria may be a useful step toward mitigating post-prostate biopsy sepsis. PMID:28280717

  7. Measuring preoperative anxiety in patients with breast cancer using the visual analog scale.

    2014-10-01

    Preoperative anxiety is a prevalent concern with deleterious effects in patient recovery and is not routinely assessed in the preoperative screening process. When it is assessed, it may prompt an increase in the use of anesthetic agents, heightened postoperative pain, and prolonged hospitalization. Preoperative women with breast cancer face anxiety as it relates to anesthesia, surgery, and recovery. The preoperative anxiety visual analog scale may identify and quantify anxiety in this population, provide advocacy and support, and improve the preoperative screening process.

    Psychosocial interventions can improve eating behaviours and psychosocial functioning in bariatric surgery candidates. However, those that involve face-to-face sessions are problematic for individuals with severe obesity due to mobility issues and practical barriers. To examine the efficacy of a pre-operative telephone-based cognitive behavioural therapy (Tele-CBT) intervention versus standard pre-operative care for improving eating psychopathology and psychosocial functioning. Preoperative bariatric surgery patients (N = 47) were randomly assigned to receive standard preoperative care (n = 24) or 6 sessions of Tele-CBT (n = 23). Retention was 74.5% at post-intervention. Intent-to-treat analyses indicated that the Tele-CBT group reported significant improvements on the Binge Eating Scale (BES), t (22) = 2.81, p = .01, Emotional Eating Scale (EES), t (22) = 3.44, p = .002, and Patient Health Questionnaire-9 (PHQ-9), t (22) = 2.71, p = .01, whereas the standard care control group actually reported significant increases on the EES, t (23) = 4.86, p < .001, PHQ-9, t (23) = 2.75, p = .01, and General Anxiety Disorder-7 (GAD-7), t (23) = 2.93, p = .008 over the same time period. Tele-CBT holds promise as a brief intervention for improving eating psychopathology and depression in bariatric surgery candidates. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Tools used in the assessment of obstetric brachial plexus injuries (OBPIs) have traditionally included electrodiagnostic studies, computerized tomography with myelography, and MRI. However, the utility of ultrasound (US) in infants for such assessment has not been extensively examined. This retrospective case series reports the preoperative brachial plexus US findings in 8 patients with OBPI and compares US with intraoperative findings. When available, the preoperative US was compared with the preoperative MRI. US revealed abnormalities in all 8 patients. Although MRI detected abnormalities in the majority of patients, US provided accurate information regarding severity and anatomic location of injury in some patients. US is a relatively inexpensive, noninvasive, painless diagnostic modality that can be used to assess OBPI. This case series suggests that US is a valuable adjunct to current diagnostic modalities.

    Juvenile angiofibromas (JA) are highly vascular, benign tumours for which surgery is the treatment of choice. In most services, embolisation is performed prior to resection. Nevertheless, there are few data on the complications of preoperative embolisation for JA. To describe major and minor complications of preoperative embolisation in a 32-year experience of patients undergoing surgical resection of JA at a tertiary hospital. Retrospective chart review study of 170 patients who underwent surgical resection of JA at a tertiary hospital between September 1976 and July 2008. All patients were male. Age ranged from 9 to 26 years. Ninety-one patients had no complications after embolisation. Overall, 105 complication events occurred of which four major and 101 minor. In our series, preoperative embolisation for JA produced no irreversible complications and no aesthetic or functional sequelae. The vast majority of complications were transient and amenable to clinical management.

    Contemporary medicine and nursing use music to stabilize mood, relieve tension and anxiety, and achieve higher treatment efficiency. Preoperative anxiety may be responsible for cognitive and behavioral changes affecting treatment efficiency. To evaluate the effect of background music on preoperative anxiety in elective surgery patients and on noise levels in the surgery waiting room. One hundred fifty-nine elective surgery patients were divided into an intervention group (n = 82) and a control group (n = 77). Data were collected and evaluated on the evening before surgery in the department, on entering the waiting room, and 30 minutes later in the preoperative setting. Data were gathered using the State-Trait Anxiety Inventory scale and by measuring vital signs. Daily noise levels in the preoperative waiting room were recorded as well. Exposure to background music was associated with decreased levels of state anxiety irrespective of age, sex, and previous exposure to surgery or anesthesia (P < .001). Background music was also related to environmental noise reduction in the surgery waiting room (P < .0001). Background music can be useful as a means of decreasing preoperative anxiety.

    To review the records of 50 children who underwent open joint washout for septic arthritis with (n=25) or without (n=25) preoperative antibiotics. Records of 50 children who underwent open joint washout for presumed septic arthritis with (n=25) or without (n=25) preoperative antibiotics were reviewed. 17 boys and 8 girls aged 3 weeks to 16 years (median, 1.5 years) who were prescribed preoperative antibiotics before joint washout were compared with 12 boys and 13 girls aged one month to 14 years (median, 2 years) who were not. Following arthrotomy and washout, all patients were commenced on high-dose intravenous antibiotics. Patients were followed up for 6 to 18 months until asymptomatic. Patients who were referred from places other than our emergency department were twice as likely to have been prescribed preoperative antibiotics (p=0.0032). Patients prescribed preoperative antibiotics had a longer median (range) time from symptom onset to joint washout (8 [2-23] vs. 4 [1-29] days, p=0.05) and a higher mean erythrocyte sedimentation rate (93.1 vs. 54.3 mm/h, p=0.023) at presentation. Nonetheless, the 2 groups were comparable for weight bearing status, fever, and positive culture, as well as the mean (range) duration of antibiotic treatment (4.9 [4-7] vs. 4.7 [1-8] weeks, p=0.586). Preoperative antibiotics should be avoided in the management of septic arthritis in children. Their prescription delays diagnosis and definitive surgery, and leads to additional washouts and complications. A high index of suspicion and expedite referral to a specialist paediatric orthopaedic unit is needed if septic arthritis is suspected.

    To determine whether mixed-flora preoperative urine cultures, as compared with no-growth preoperative urine cultures, are associated with a higher prevalence of postoperative urinary tract infections (UTIs). This was a retrospective cohort study. Women who underwent urogynecologic surgery were included if their preoperative clean-catch urine culture result was mixed flora or no growth. Women were excluded if they received postoperative antibiotics for reasons other than treatment of a UTI. Women were divided into two cohorts based on preoperative urine culture results-mixed flora or no growth; the prevalence of postoperative UTI was compared between cohorts. Baseline characteristics were compared using χ(2) or Student t tests. A logistic regression analysis then was performed. We included 282 women who were predominantly postmenopausal, white, and overweight. There were many concomitant procedures; 46% underwent a midurethral sling procedure and 68% underwent pelvic organ prolapse surgery. Preoperative urine cultures resulted as mixed flora in 192 (68%) and no growth in 90 (32%) patients. Overall, 14% were treated for a UTI postoperatively. There was no difference in the proportion of patients treated for a postoperative UTI between the two cohorts (25 mixed flora vs 13 no growth, P = 0.77). These results remained when controlling for potentially confounding variables in a logistic regression model (adjusted odds ratio 0.92, 95% confidence interval 0.43-1.96). In women with mixed-flora compared with no-growth preoperative urine cultures, there were no differences in the prevalence of postoperative UTI. The clinical practice of interpreting mixed-flora cultures as negative is appropriate.

    Recent evidence indicates that a preoperative warm-up is a potentially useful tool in facilitating performance. But what factors drive such improvements and how should a warm-up be implemented? In order to address these issues, we adopted a two-pronged approach: (1) we conducted a systematic review of the literature to identify existing studies utilising preoperative simulation techniques; (2) we performed task analysis to identify the constituent parts of effective warm-ups. We identified five randomised control trials, four randomised cross-over trials and four case series. The majority of these studies reviewed surgical performance following preoperative simulation relative to performance without simulation. Four studies reported outcome measures in real patients and the remainder reported simulated outcome measures. All but one of the studies found that preoperative simulation improves operative outcomes-but this improvement was not found across all measured parameters. While the reviewed studies had a number of methodological issues, the global data indicate that preoperative simulation has substantial potential to improve surgical performance. Analysis of the task characteristics of successful interventions indicated that the majority of these studies employed warm-ups that focused on the visual motor elements of surgery. However, there was no theoretical or empirical basis to inform the design of the intervention in any of these studies. There is an urgent need for a more rigorous approach to the development of "warm-up" routines if the potential value of preoperative simulation is to be understood and realised. We propose that such interventions need to be grounded in theory and empirical evidence on human motor performance.

    Obesity affects 32% of adults in the USA. Surgery generates substantial weight loss, but 20-30% fails to achieve successful weight loss. Our objective was to identify preoperative psychosocial factors associated with weight loss following bariatric surgery. We performed a literature search of PubMed® and the Cochrane Database of Reviews of Effectiveness between 1988 and April 2010. Articles were screened for bariatric surgery and weight loss if they included a preoperative predictor of weight loss: body mass index (BMI), preoperative weight loss, eating disorders, or psychiatric disorder/substance abuse. One thousand seven titles were reviewed, 534 articles screened, and 115 included in the review. Factors that may be positively associated with weight loss after surgery include mandatory preoperative weight loss (7 of 14 studies with positive association). Factors that may be negatively associated with weight loss include preoperative BMI (37 out of 62 studies with negative association), super-obesity (24 out of 33 studies), and personality disorders (7 out of 14 studies). Meta-analysis revealed a decrease of 10.1% excess weight loss (EWL) for super-obese patients (95% confidence interval (CI) [3.7-16.5%]), though there was significant heterogeneity in the meta-analysis, and an increase of 5.9% EWL for patients with binge eating at 12 months after surgery (95% CI [1.9-9.8%]). Further studies are necessary to investigate whether preoperative factors can predict a clinically meaningful difference in weight loss after bariatric surgery. The identification of predictive factors may improve patient selection and help develop interventions targeting specific needs of patients.

    Recent advances in preoperative and postoperative imaging have an increasing influence on surgical decision-making and make more complex surgical interventions possible. This improves the possibilities for frequently occurring challenges and promoting improved functional and oncological outcome. This manuscript reviews the role of preoperative and intraoperative imaging in surgery. Various techniques are explained based on examples from hepatobiliary surgery and neurosurgery, in particular real-time procedures, such as the online use of augmented reality and in vivo fluorescence, as well as new and promising optical techniques including imaging of intrinsic signals and vibrational spectroscopy.

    Anemia is common in cancer patients and is associated with reduced survival. Recent studies document that treatment of anemia with blood transfusion in cancer patients is associated with increased infection risk, tumor recurrence, and mortality. We therefore investigated the incidence of preoperative anemia in colorectal cancer and assessed risk factors for anemia. Prospective data were collected on 311 patients diagnosed with colorectal cancer over a 6-year period from 1994 through 1999. Patients were stratified by age, gender, presenting complaint, preoperative hematocrit, American Joint Committee on Cancer (AJCC) stage, and TNM classification. Discrete variables were compared using Pearson's Chi-square analysis. Continuous variables were compared using Student's t test. Differences were considered significant when P < 0.05. The mean age of the study cohort was 67 +/- 9.2 with 98 per cent of the study population being male. The mean AJCC stage was 2.2 +/- 1.2 and the mean preoperative hematocrit was 35 +/- 7.9 with an incidence of 46.1 per cent. The most common presenting complaints were hematochezia (n = 59), anemia (n = 51), heme-occult-positive stool (n = 33), bowel obstruction (n = 26), abdominal pain (n = 21), and palpable mass (n = 13). Preoperative anemia was most common in patients with right colon cancer with an incidence of 57.6 per cent followed by left colon cancer (42.2%) and rectal cancer (29.8%). Patients with right colon cancer had significantly lower preoperative hematocrits compared with left colon cancer (33 +/- 8.5 vs 36 +/- 7.4; P < 0.01) and rectal cancer (33 +/- 8.5 vs 38 +/- 6.0; P < 0.0001). Patients with right colon cancer also had significantly increased stage at presentation compared with left colon cancer (2.3 +/- 1.3 vs 2.1 +/- 1.2; P < 0.02). Age was not a significant risk factor for preoperative anemia in colorectal cancer. We conclude that there is a high incidence of anemia in patients with colon cancer. Patients with right colon

    AIM: To investigate the prognostic significance of preoperative fibrinogen levels in colon cancer patients. METHODS: A total of 255 colon cancer patients treated at the Affiliated Tumor Hospital of Xinjiang Medical University from June 1st 2005 to June 1st 2008 were enrolled in the study. All patients received radical surgery as their primary treatment method. Preoperative fibrinogen was detected by the Clauss method, and all patients were followed up after surgery. Preoperative fibrinogen measurements were correlated with a number of clinicopathological parameters using the Student t test and analysis of variance. Survival analyses were performed by the Kaplan-Meier method and Cox regression modeling to measure 5-year disease-free survival (DFS) and overall survival (OS). RESULTS: The mean preoperative fibrinogen concentration of all colon cancer patients was 3.17 ± 0.88 g/L. Statistically significant differences were found between preoperative fibrinogen levels and the clinicopathological parameters of age, smoking status, tumor size, tumor location, tumor-node-metastasis (TNM) stage, modified Glasgow prognostic scores (mGPS), white blood cell (WBC) count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and carcinoembryonic antigen (CEA) levels. Univariate survival analysis showed that TNM stage, tumor cell differentiation grade, vascular invasion, mGPS score, preoperative fibrinogen, WBC, NLR, PLR and CEA all correlated with both OS and DFS. Alpha-fetoprotein (AFP) and body mass index correlated only with OS. Kaplan-Meier analysis revealed that both OS and DFS of the total cohort, as well as of the stage II and III patients, were higher in the hypofibrinogen group compared to the hyperfibrinogen group (all P < 0.05). In contrast, there was no significant difference between OS and DFS in stage I patients with low or high fibrinogen levels. Cox regression analysis indicated preoperative fibrinogen levels, TNM stage, mGPS score, CEA, and

    Children, like adults, are required to fast before general anaesthesia with the aim of reducing the volume and acidity of their stomach contents. It is thought that fasting reduces the risk of regurgitation and aspiration of gastric contents during surgery. Recent developments have encouraged a shift from the standard 'nil-by-mouth-from-midnight' fasting policy to more relaxed regimens. Practice has been slow to change due to questions relating to the duration of a total fast, the type and amount of intake permitted. To systematically assess the effects of different fasting regimens (duration, type and volume of permitted intake) and the impact on perioperative complications and patient well being (aspiration, regurgitation, related morbidity, thirst, hunger, pain, comfort, behaviour, nausea and vomiting) in children. We searched Cochrane Wounds Group Specialised Register (searched 25/6/09), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2 2009), Ovid MEDLINE (1950 to June Week 2 2009), Ovid EMBASE (1980 to 2009 Week 25), EBSCO CINAHL (1982 to June Week 3 2009), the National Research Register, relevant conference proceedings and article reference lists and contacted experts. Randomised and quasi randomised controlled trials of preoperative fasting regimens for children were identified. Data extraction and trial quality assessment was conducted independently by three authors. Trial authors were contacted for additional information including adverse events. This first update of the review identified two additional eligible studies, bringing the total number of included studies to 25 (forty seven randomised controlled comparisons involving 2543 children considered to be at normal risk of regurgitation or aspiration during anaesthesia). Only one incidence of aspiration and regurgitation was reported.Children permitted fluids up to 120 minutes preoperatively were not found to experience higher gastric volumes or lower gastric pH values

    The aim of the study was to undertake a controlled prospective evaluation of high resolution computerized tomography in the pre-operative diagnosis of labyrinthine fistulae. Fifty consecutive patients with chronic suppurative otitis media were scanned prior to surgery, using a Siemens DRI scanner. The radiological predictions were then compared with the surgical findings. Five patients had labyrinthine erosions and these were predicted in 4 out of the 5 (80%). The one erosion that escaped radiological detection was less than 2 mm in length. The study shows that high resolution computerized tomography is a highly accurate method for demonstrating pre-operatively all but the smallest fistulae.

    Annual patient attendances at a pre-operative assessment department increased by 24.8% from 5659 in 2009, to 7062 in 2012. The unit was staffed by administrative staff, nurses, and health care assistants (HCA). Medical review was accessed via on call medical staff, or notes were sent to anaesthetists for further review. With rising demand, patient waits increased. The average lead time for a patient (time from entering the department to leaving) was 79 minutes. 9.3% of patients attended within two weeks of their scheduled surgery date. 10% of patients were asked to return on a later day, as there was not sufficient capacity to undertake their assessment. There were nine routes of referral in to the department. Patients moved between different clinic rooms and the waiting area several times. Work patterns were uneven, as many attendances were from out-patient clinics which meant peak attendance times were linked to clinic times. There were substantial differences in the approaches of different nurses, making the HCA role difficult. Patients reported dissatisfaction with waits. Using a Lean quality improvement process with rapid PDSA cycles, the service changed to one in which patients were placed in a room, and remained there for the duration of their assessment. Standard work was developed for HCWs and nurses. Rooms were standardised using 5S processes, and set up improved to reduce time spent looking for supplies. A co-ordinator role was introduced using existing staff to monitor flow and to organise the required medical assessments and ECGs. Timing of booked appointments were altered to take account of clinic times. Routes in to the department were reduced from nine to one. Ten months after the work began, the average lead time had reduced to 59 minutes. The proportion of people attending within two weeks of their surgery decreased from 9.3% to 5.3%. Referrals for an anaesthetic opinion decreased from 30% to 20%, and in the month reviewed no one had to return to

    Blood conservation is an important aspect of care provided to the patients undergoing cardiac operations with cardiopulmonary bypass (CPB). It is even more important in patients with anticipated prolonged CPB, redo cardiac surgery, patients having negative blood group and in patients undergoing emergency cardiac surgery. In prolonged CPB the blood is subjected to more destruction of important coagulation factors, in redo surgery the separation of adhesions leads to increased bleeding and difficulty in achieving the haemostasis and in patients with negative blood group and emergency operations, the availability of sufficient blood can be a problem. Harvesting the autologous platelet rich plasma (PRP) can be a useful method of blood conservation in these patients. The above four categories of patients were prospectively studied, using either autologous whole blood donation or autologous platelet rich plasma (PRP) harvest in the immediate pre-bypass period. Forty two patients were included in the study and randomly divided into two equal groups of 21 each, control group (Group I) in which one unit of whole blood was withdrawn, and PRP group (Group II) where autologous plateletpheresis was utilised. After reversal of heparin, autologous whole blood was transfused in the control group and autologous PRP was transfused in the PRP group. The chest tube drainage and the requirement of homologous blood and blood products were recorded. Average PRP harvest was 643.33 +/- 133.51 mL in PRP group and the mean whole blood donation was 333.75 +/- 79.58 mL in the control group. Demographic, preoperative and intra operative data showed no statistically significant differences between the two groups. The PRP group patients drained 26.44% less (p<0.001) and required 38.5% less homologous blood and blood products (p<0.05), in the postoperative period. Haemoglobin levels on day zero (day of operation) and day three were statistically not different between the two groups. We conclude

    The definition of substernal goiter (SG) is based on variable criteria leading to a considerable variation in the reported incidence (from 0.2% to 45%). The peri- and postoperative complications are higher in total thyroidectomy (TT) for SG than that for cervical goiter. The aim of this study was to evaluate the preoperative risk factors associated with postoperative complications. From 2002 to 2014, 142 (8.5%; 98 women and 44 men) of the 1690 patients who underwent TT had a SG. We retrospectively evaluated the following parameters: sex, age, histology, pre- and retrovascular position, recurrence, and extension beyond the carina. These parameters were then related to the postoperative complications: seroma/hematoma, transient and permanent hypocalcemia, transient and permanent laryngeal nerve palsy, and the length of surgery. The results were further compared with a control group of 120 patients operated on in the same period with TT for cervical goiter. All but two procedures were terminated via cervicotomy, where partial sternotomies were required. No perioperative mortality was observed. Results of the statistical analysis (Student’s t-test and Fisher’s exact test) indicated an association between recurrence and extension beyond the carina with all postoperative complications. The group that underwent TT of SG showed a statistically significant higher risk for transient hypocalcemia (relative risk =1.767 with 95% confidence interval: 1.131–2.7605, P=0.0124, and need to treat =7.1) and a trend toward significance for transient recurrent laryngeal nerve palsy (relative risk =6.7806 with 95% confidence interval: 0.8577–53.2898, P=0.0696, and need to treat =20.8) compared to the group that underwent TT of cervical goiter. TT is the procedure to perform in SG even if the incidence of complications is higher than for cervical goiters. The major risk factors associated with postoperative complications are recurrence and extension beyond the carina. In the

Evidence of a preoperative rehabilitation assessment after the index surgical stay admission but before the surgical date. Evidence was found that 343 of 4226 veterans (8.12%) with lower extremity amputations received preoperative rehabilitation assessments. Veterans receiving preoperative rehabilitation were more likely to be older, admitted from home, or transferred from another hospital. Patients who underwent surgical amputation at smaller-sized hospitals or in the South Central or Mountain Pacific regions were more likely to receive preoperative rehabilitation compared with patients in mid-sized hospitals or in the Northeast, Southeast, or Midwest regions. Patients with evidence of paralysis, patients treated in facilities with programs accredited by the Commission on Accreditation of Rehabilitation Facilities (P < .01), and patients in the second data wave were less likely to receive preoperative rehabilitation.

    Objective Post-operative delirium is associated with pre-operative cognitive difficulties and diminished functional independence, both of which suggest that brain pathology may be present in affected individuals prior to surgery. Currently, there are few studies that have examined imaging correlates of post-operative delirium. To our knowledge, none have examined the association of delirium with existing structural pathology in pre-operative cancer patients. Here, we present a novel, retrospective strategy to assess pre-operative structural brain pathology and its association with post-operative delirium. Standard of care structural magnetic resonance imaging (MRIs) from a cohort of surgical candidates prior to surgery were analyzed for white matter hyperintensities and cerebral atrophy. Methods We identified 23 non-small cell lung cancer patients with no evidence of metastases in the brain pre-operatively, through retrospective chart review, who met criteria for post-operative delirium within 4 days of surgery. 24 age- and gender-matched control subjects were identified for comparison to the delirium sample. T1 and fluid-attenuated inversion recovery sequences were collected from standard of care pre-operative MRI screening and assessed for white matter pathology and atrophy. Results We found significant differences in white matter pathology between groups with the delirium group exhibiting significantly greater white matter pathology than the non-delirium group. Measure of cerebral atrophy demonstrated no significant difference between the delirium and non-delirium group. Conclusions In this preliminary study utilizing standard of care pre-operative brain MRIs for assessment of structural risk factors to delirium, we found white matter pathology to be a significant risk factor in post-operative delirium.

    Multicenter, randomized, controlled trial on preoperative pain neuroscience education (NE) for lumbar radiculopathy. To determine if the addition of NE to usual preoperative education would result in superior outcomes with regard to pain, function, surgical experience, and health care utilization postsurgery. One in 4 patients after lumbar surgery (LS) for radiculopathy experience persistent pain and disability, which is nonresponsive to perioperative treatments. NE focusing on the neurophysiology of pain has been shown to decrease pain and disability in populations with chronic low back pain. Eligible patients scheduled for LS for radiculopathy were randomized to receive either preoperative usual care (UC) or a combination of UC plus 1 session of NE delivered by a physical therapist (verbal one-on-one format) and a NE booklet. Sixty-seven patients completed the following outcomes prior to LS (baseline), and 1, 3, 6, and 12 months after LS: low back pain (numeric rating scale), leg pain (numeric rating scale), function (Oswestry Disability Index), various beliefs and experiences related to LS (10-item survey with Likert scale responses), and postoperative utilization of health care (utilization of health care questionnaire). At 1-year follow-up, there were no statistical differences between the experimental and control groups with regard to primary outcome measure of low back pain (P = 0.183), leg pain (P = 0.075), and function (P = 0.365). In a majority of the categories regarding surgical experience, the NE group scored significantly better: better prepared for LS (P = 0.001); preoperative session preparing them for LS (P < 0.001) and LS meeting their expectations (P = 0.021). Health care utilization post-LS also favored the NE group (P = 0.007) resulting in 45% less health care expenditure compared with the control group in the 1-year follow-up period. NE resulted in significant behavior change. Despite a similar pain and functional trajectory during the 1-year

    Patients with colorectal cancer who need a stoma should undergo preoperative marking of the stoma site and education by a trained stomatherapist. This study examined the care received by ostomy patients with colorectal cancer in Spanish colorectal surgery units, to assess its quality and to detect areas for improvement. A prospective study was conducted in twelve Spanish colorectal surgery units in Spain including patients visited by the stomatherapist after surgery for colorectal cancer. Each patient answered a questionnaire about their stoma care. Between September 2007 and May 2008, 270 patients were included, (63% colostomies, 37% ileostomies). Of whom; 75% had elective and 25% emergency surgery. Stomatherapist marked the stoma site in 45,6% of patients (0% emergency created stomas and 58,8% elective). However, patients who saw a stoma therapist preoperatively presented significantly lower rates of stoma complications (p < 0.001) and anxiety (p < 0.001) compared to those who did not postoperatively. The study has demonstrated the importance of preoperative stomatherapy assessment.

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether preoperative physiotherapy/pulmonary rehabilitation is beneficial for patients undergoing lung resection. Ten papers were identified using the reported search, of which five represented the best evidence to answer the clinical question. In 2007 a report showed in 13 subjects receiving a preoperative rehabilitation programme (PRP) an improvement of maximum oxygen uptake consumption (VO(2) max) of an average 2.4 ml/kg/min (95% confidence interval 1-3.8; P=0.002). A report in 2008 showed in 12 patients with chronic obstructive pulmonary disease (COPD) and VO(2) max <15 ml/kg/min that PRP could effect a mean improvement in VO(2) max of 2.8 ml/kg/min (P<0.001). An earlier report in 2005 demonstrated a reduced length of hospital stay (21±7 days vs. 29±9 days; P=0.0003) in 22 subjects who underwent PRP for two weeks compared with a historical control of 60 patients with COPD. It was shown in 2006 that by using a cross-sectional design with historical controls that one day of chest physiotherapy comprising inspiratory and peripheral muscle training compared with routine nursing care was associated with a lower atelectasis rate (2% vs. 7.7%) and a median length of stay that was 5.73 days vs. 8.33 days (P<0.0001). A prospective randomised controlled study in 1997, showed that two weeks of PRP followed by two months of postoperative rehabilitation produced a better predicted postoperative forced expiratory volume in one second in the study group than in the control group at three months (lobectomy + 570 ml vs. -70 ml; pneumonectomy + 680 ml vs. -110 ml). We conclude that preoperative physiotherapy improves exercise capacity and preserves pulmonary function following surgery. Whether these benefits translate into a reduction in postoperative pulmonary complication is uncertain.

    Preoperative autologous blood donation is employed with increasing frequency, particularly in patients undergoing elective orthopedic procedures. While autologous transfusion decreases the incidence of postoperative infections and other complications, the cost-effectiveness of this therapy has not been fully investigated. We constructed a decision analytic model to study the cost-effectiveness of preoperative autologous blood donation of packed red blood cells compared with allogeneic packed red blood cells in primary hip arthroplasty. We used data from 73 patients presenting at our blood center with a prescription for 2 U of autologous red blood cells prior to hip arthroplasty to establish probabilities for the number of units that would be donated. Patients were able to donate an average of 1.9 U (range, 0 to 2 U) of autologous blood. We also reviewed the charts of 56 patients who underwent primary hip arthroplasty to model the number of units given during hospitalization (1.5 U given; range, 0 to 5 U). We applied the model to a 65-year-old patient undergoing primary hip arthroplasty. Estimates for the incidence of posttransfusion hepatitis, chronic active hepatitis, human immunodeficiency virus infection, postoperative bacterial infection, and fatal hemolytic transfusion reaction were derived from the literature. Patient utility was measured in life-years. Costs included the cost of preoperative autologous blood donation, blood administration, and medical care costs associated with the complications of transfusion. Costs were derived from local data and the literature. Future earnings lost were not modeled. In the baseline analysis, autologous transfusion results in a net cost savings compared with allogeneic blood over a wide range of complication rates, patient ages, and transfusion requirements. The dominant factor in the analysis is the effect of postoperative bacterial infection on length of hospital stay and the resultant increase in costs. The effect of

    Purpose: The addition of concomitant chemotherapy to preoperative radiotherapy is considered the standard of care for patients with cT3-4 rectal cancer. The combined treatment modality increases the complete response rate and local control (LC), but has no impact on survival or the incidence of distant metastases. In addition, it is associated with considerable toxicity. As an alternative strategy, we explored prospectively, preoperative helical tomotherapy with a simultaneous integrated boost (SIB). Methods and Materials: A total of 108 patients were treated with intensity-modulated and image-guided radiotherapy using the Tomotherapy Hi-Art II system. A dose of 46 Gy, in daily fractions of 2 Gy, was delivered to the mesorectum and draining lymph nodes, without concomitant chemotherapy. Patients with an anticipated circumferential resection margin (CRM) of less than 2 mm, based on magnetic resonance imaging, received a SIB to the tumor up to a total dose of 55.2 Gy. Acute and late side effects were scored using the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. Results: A total of 102 patients presented with cT3-4 tumors; 57 patients entered the boost group and 51 the no-boost group. One patient in the no-boost group developed a radio-hypersensitivity reaction, resulting in a complete tumor remission, a Grade 3 acute and Grade 5 late enteritis. No other Grade {>=}3 acute toxicities occurred. With a median follow-up of 32 months, Grade {>=}3 late gastrointestinal and urinary toxicity were observed in 6% and 4% of the patients, respectively. The actuarial 2-year LC, progression-free survival and overall survival were 98%, 79%, and 93%. Conclusions: Preoperative helical tomotherapy displays a favorable acute toxicity profile in patients with cT3-4 rectal cancer. A SIB can be safely administered in patients with a narrow CRM and resulted in a promising LC.

    Endoscopic retrograde cholangiopancreatography (ERCP) is frequently used preoperatively in adult patients with suspected choledocholithiasis. Cholelithiasis occurs much less often in children, and the indications for ERCP are not established. We hypothesized that the natural history of choledocholithiasis in children is spontaneous passage of stones through the papilla and that these children can be managed without routine preoperative ERCP. Retrospective analysis of patients treated over a 10-year period. Tertiary care children's hospital. All patients with cholecystectomy for biliary disease. Cholecystectomy; intraoperative cholangiography for suspected choledocholithiasis: hyperbilirubinemia, gallstone pancreatitis, and ultrasonographic evidence of common bile duct dilation or common bile duct stones; and postoperative ERCP for symptomatic choledocholithiasis: pain and jaundice. Incidence and complications of choledocholithiasis and frequency of ERCP. One hundred patients (63 females) were studied. Indications included acute cholecystitis (10%), chronic cholecystitis (59%), gallstone pancreatitis (26%), and choledocholithiasis (5%). An intraoperative cholangiography was performed in 45 patients, and common bile duct stones were identified in 13. Expectant management of asymptomatic common bile duct stones was associated with sonographic resolution within 1 week. One patient with intraoperative cholangiography-proven choledocholithiasis required ERCP for symptoms 24 hours after operation. One additional patient, who did not undergo intraoperative cholangiography, developed symptomatic choledocholithiasis and required ERCP. There were no choledocholithiasis- or ERCP-related complications. This study suggests that choledocholithiasis occurs frequently in children and that spontaneous passage of common bile duct stones is common. This could explain the relatively high incidence of gallstone pancreatitis. Conservative management of choledocholithiasis is successful

    Breast hypertrophy is often associated with functional limitations. Beyond the aesthetic concerns, breast reduction can improve symptoms and self-esteem. In different countries, health-care system regulations have fixed the threshold for reimbursement in 500 g of predicted tissue resection for each breast. Different preoperative measurements have been proposed to predict breast-tissue weight to be removed, showing a variable correlation with post-operative evaluation. We describe a reliable, simple measurement to predict the quantity of breast reduction in grams, which can be applicable to any surgical technique. A total of 128 patients undergoing bilateral breast reduction were evaluated. The correlation between the preoperative nipple-areola complex (NAC) lift distance and the weight of removed breast tissue was tested with linear regression and Pearson's test. Other anthropometric measurements were tested as a control. The ratio between resected grams and lift distance was explored to find a multiplication coefficient to be used at preoperative planning. The mean resection weight was 686.65 g. The mean NAC-lift distance was 7.6 cm. Positive correlation between the NAC-lift distance and the weight of breast tissue removed was found (r: 0.87; p < 0.001). The mean weight of the removed breast tissue (g) per centimetre of NAC lift was 81 g/cm in the group between 6 and 12 cm and 70 g/cm in the group with >12 cm of lift distance. The NAC-lift distance is a single, objective, repeatable measure that can provide a reliable prediction of breast-tissue grams to be removed; it helps in classifying breast-reduction indications.

    Previous studies have shown that the use of intraoperative instructional videos has a positive effect on learning laparoscopic procedures. This study investigated the effect of the timing of the instructional videos on learning curves in laparoscopic skills training. After completing a basic skills course on a virtual reality simulator, medical students and residents with less than 1 hour experience using laparoscopic instruments were randomized into 2 groups. Using an instructional video either preoperatively or intraoperatively, both groups then performed 4 repetitions of a standardized task on the TrEndo augmented reality. With the TrEndo, 9 motion analysis parameters (MAPs) were recorded for each session (4 MAPs for each hand and time). These were the primary outcome measurements for performance. The time spent watching the instructional video was also recorded. Improvement in performance was studied within and between groups. Medical Center Leeuwarden, a secondary care hospital located in Leeuwarden, The Netherlands. Right-hand dominant medical student and residents with more than 1 hour experience operating any kind of laparoscopic instruments were participated. A total of 23 persons entered the study, of which 21 completed the study course. In both groups, at least 5 of 9 MAPs showed significant improvements between repetition 1 and 4. When both groups were compared after completion of repetition 4, no significant differences in improvement were detected. The intraoperative group showed significant improvement in 3 MAPs of the left-nondominant-hand, compared with one MAP for the preoperative group. No significant differences in learning curves could be detected between the subjects who used intraoperative instructional videos and those who used preoperative instructional videos. Intraoperative video instruction may result in improved dexterity of the nondominant hand. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc

    Preoperative screening for nasal S. aureus carriage, followed by eradication treatment of identified carriers with nasal mupirocine ointment and chlorhexidine soap was highly effective in preventing deep-seated S. aureus infections. It is unknown how cost-effectiveness of this intervention is affected by suboptimal S. aureus screening. We determined cost-effectiveness of different preoperative S. aureus screening regimes. We compared different screening scenarios (ranging from treating all patients without screening to treating only identified S. aureus carriers) to the base case scenario without any screening and treatment. Screening and treatment costs as well as costs and mortality due to deep-seated S. aureus infection were derived from hospital databases and prospectively collected data, respectively. As compared to the base case scenario, all scenarios are associated with improved health care outcomes at reduced costs. Treating all patients without screening is most cost-beneficial, saving €7339 per life year gained, as compared to €3330 when only identified carriers are treated. In sensitivity analysis, outcomes are susceptible to the sensitivity of the screening test and the efficacy of treatment. Reductions in these parameters would reduce the cost-effectiveness of scenarios in which treatment is based on screening. When only identified S. aureus carriers are treated costs of screening should be less than €6.23 to become the dominant strategy. Preoperative screening and eradication of S. aureus carriage to prevent deep-seated S. aureus infections saves both life years and medical costs at the same time, although treating all patients without screening is the dominant strategy, resulting in most health gains and largest savings.

    Introduction: Periacetabular osteotomy (PAO) is an effective joint-preserving procedure for young adults with developmental dysplasia of the hip. Although PAO provides excellent radiographic and clinical results, it is a technically demanding procedure with a distinct learning curve that requires careful 3D planning and, above all, has a number of potential complications. We therefore developed a pre-operative simulation method for PAO via creation of a new full-scale model. Methods: The model was prepared from the patient’s Digital Imaging and Communications in Medicine (DICOM) formatted data from computed tomography (CT), for construction and assembly using 3D printing technology. A major feature of our model is that it is constructed from salt. In contrast to conventional models, our model provides a more accurate representation, at a lower manufacturing cost, and requires a shorter production time. Furthermore, our model realized simulated operation normally with using a chisel and drill without easy breakage or fissure. We were able to easily simulate the line of osteotomy and confirm acetabular version and coverage after moving to the osteotomized fragment. Additionally, this model allowed a dynamic assessment that avoided anterior impingement following the osteotomy. Results: Our models clearly reflected the anatomical shape of the patient’s hip. Our models allowed for surgical simulation, making realistic use of the chisel and drill. Our method of pre-operative simulation for PAO allowed for the assessment of accurate osteotomy line, determination of the position of the osteotomized fragment, and prevented anterior impingement after the operation. Conclusion: Our method of pre-operative simulation might improve the safety, accuracy, and results of PAO. PMID:28186873

    Accommodating a novel semi-implantable bone conduction hearing device within the temporal bone presents challenges for surgical planning. This study describes the utility of CT in pre-operative assessment of such an implant. Retrospective review of pre-operative CT, clinical and surgical records of 16 adults considered for device implantation. Radiological suitability was assessed on CT using 3D simulation software. Antero-posterior (AP) dimensions of the mastoid bone and minimum skull thickness were measured. CT planning results were correlated with operative records. Eight and five candidates were suitable for device placement in the transmastoid and retrosigmoid positions, respectively, and three were radiologically unsuitable. The mean AP diameter of the mastoid cavity was 14.6 mm for the transmastoid group and 4.6 mm for the retrosigmoid group (p < 0.05). Contracted mastoid and/or prior surgery were predisposing factors for unsuitability. Four transmastoid and five retrosigmoid positions required sigmoid sinus/dural depression and/or use of lifts due to insufficient bone capacity. A high proportion of patients being considered have contracted or operated mastoids, which reduces the feasibility of the transmastoid approach. This finding combined with the complex temporal bone geometry illustrates the importance of careful CT evaluation using 3D software for precise device simulation. • Preoperative temporal bone CT is essential for determining Bonebridge device suitability. • Mastoid under-pneumatisation and prior mastoidectomy predict a retrosigmoid Bonebridge position. • 3D simulation software is recommended for precise device positioning.

    Background: Preoperative radiation therapy with 5-fluorouracil chemotherapy is a standard of care for cT3-4 rectal cancer. Studies incorporating additional cytotoxic agents demonstrate increased morbidity with little benefit. We evaluate a template that: (1) includes the benefits of preoperative radiation therapy on local response/control; (2) provides preoperative multidrug chemotherapy; and (3) avoids the morbidity of concurrent radiation therapy and multidrug chemotherapy. Methods and Materials: Patients with cT3-4, any N, any M rectal cancer were eligible. Patients were confirmed to be candidates for pelvic surgery, provided response was sufficient. Preoperative treatment was 5 fractions radiation therapy (25 Gy to involved mesorectum, 20 Gy to elective nodes), followed by 4 cycles of FOLFOX [5-fluorouracil, oxaliplatin, leucovorin]. Extirpative surgery was performed 4 to 9 weeks after preoperative chemotherapy. Postoperative chemotherapy was at the discretion of the medical oncologist. The principal objectives were to achieve T stage downstaging (ypT < cT) and preoperative grade 3+ gastrointestinal morbidity equal to or better than that of historical controls. Results: 76 evaluable cases included 7 cT4 and 69 cT3; 59 (78%) cN+, and 7 cM1. Grade 3 preoperative GI morbidity occurred in 7 cases (9%) (no grade 4 or 5). Sphincter-preserving surgery was performed on 57 (75%) patients. At surgery, 53 patients (70%) had ypT0-2 residual disease, including 21 (28%) ypT0 and 19 (25%) ypT0N0 (complete response); 24 (32%) were ypN+. At 30 months, local control for all evaluable cases and freedom from disease for M0 evaluable cases were, respectively, 95% (95% confidence interval [CI]: 89%-100%) and 87% (95% CI: 76%-98%). Cases were subanalyzed by whether disease met requirements for the recently activated PROSPECT trial for intermediate-risk rectal cancer. Thirty-eight patients met PROSPECT eligibility and achieved 16 ypT0 (42%), 15 ypT0N0 (39%), and 33 ypT0-2 (87

    This study compared the effects of preoperative physical therapy of general cardiovascular conditioning exercises with the routine procedure of no preoperative physical therapy on patients undergoing primary total knee replacement. Thirty patients were randomly assigned to 1 of 3 groups. Group 1 was the control group. Group 2 participated in a physical therapy program designed to strengthen the upper and lower limbs and improve knee range of motion. Group 3 participated in a cardiovascular conditioning program, consisting of arm ergometry, cycle ergometry, aquatic exercises, and aerobic activity. All patients were evaluated preoperatively and postoperatively using the Hospital for Special Surgery Knee Rating, the Arthritis Impact Measurement Scale, and the Quality of Well Being instrument. Both experimental groups tolerated their respective exercise protocols extremely well. All 3 groups showed significant improvement postoperatively as measured by the Hospital for Special Surgery Knee Rating, the Arthritis Impact Measurement Scale and the Quality of Well Being measurement scales. However, neither type of preoperative exercise added to the degree of improvement after surgery at any of the postoperative evaluations.

    Purpose: To analyze the rate of pathologic response in patients with locally advanced gastric cancer treated with preoperative chemotherapy with and without chemoradiation at our institution. Methods and Materials: From 2000 to 2007 patients were retrospectively identified who received preoperative treatment for gastric cancer (cT3-4/ N+) with induction chemotherapy (Ch) or with Ch followed by concurrent chemoradiotherapy (45 Gy in 5 weeks) (ChRT). Surgery was planned 4-6 weeks after the completion of neoadjuvant treatment. Pathologic assessment was used to investigate the patterns of pathologic response after neoadjuvant treatment. Results: Sixty-one patients were analyzed. Of 61 patients, 58 (95%) underwent surgery. The R0 resection rate was 87%. Pathologic complete response was achieved in 12% of the patients. A major pathologic response (<10% of residual tumor) was observed in 53% of patients, and T downstaging was observed in 75%. Median follow-up was 38.7 months. Median disease-free survival (DFS) was 36.5 months. The only patient-, tumor-, and treatment-related factor associated with pathologic response was the use of preoperative ChRT. Patients achieving major pathologic response had a 3-year actuarial DFS rate of 63%. Conclusions: The patterns of pathologic response after preoperative ChRT suggest encouraging intervals of DFS. Such a strategy may be of interest to be explored in gastric cancer.

  6. Does planned intravenous sedation affect preoperative anxiety in patients?

    Dental surgery generally causes stress and fear, which may affect patient physiology and increase perioperative anxiety. Dental anxiety is considered to be an important factor in determining the need for intravenous sedation. One of the gold standards for measuring preoperative anxiety is Spielberger's State-Trait Anxiety Inventory (STAI). The authors have previously assessed preoperative anxiety using STAI and recommended that intravenous sedation be performed for patients whose anxiety level is high. The intravenous cannulation necessary for sedation and sedation itself may increase anxiety. The authors carried out this study to examine whether planning intravenous sedation before surgery increases preoperative anxiety. The subjects were patients who planned to undergo wisdom teeth extraction under local anaesthesia in the authors' hospital. They were divided into two groups on the basis of the planned intravenous sedation. STAI scores were compared between the initial visit and just before surgery. There were no significant differences in the state and trait anxiety scores between the initial visit and the day of the surgery in the two groups. Planned intravenous sedation based on the evaluation of anxiety levels using STAI is effective for promoting a safe operation without aggravating preoperative anxiety.

    Background Digital mammography clearly distinguishes gland tissue density from the overlying non-glandular breast tissue coverage, which corresponds to the existing tissue between the skin and the Cooper’s ligaments surrounding the gland (i.e., dermis and subcutaneous fat). Preoperative digital imaging can determine the thickness of this breast tissue coverage, thus facilitating planning of the most adequate surgical techniques and reconstructive procedures for each case. Methods This study aimed to describe the results of a retrospective study of 352 digital mammograms in 176 patients with different breast volumes who underwent preoperative conservative mastectomies. The breast tissue coverage thickness and its relationship with the breast volume were evaluated. Results The breast tissue coverage thickness ranged from 0.233 to 4.423 cm, with a mean value of 1.952 cm. A comparison of tissue coverage and breast volume revealed a non-direct relationship between these factors. Conclusions Preoperative planning should not depend only on breast volume. Flap evaluations based on preoperative imaging measurements might be helpful when planning a conservative mastectomy. Accordingly, we propose a breast tissue coverage classification (BTCC).

    Purpose of review The field of temporal bone simulation (TBS) has largely focused on the development and validation of simulators as training and assessment tools. However, as technology has progressed over the years, researchers have envisioned new clinical applications for simulators extending to pre-operative surgical planning and case rehearsal. The purpose of this article is to review the current state of the art in TBS and to highlight recent advancements in the field. Due to space limitations, we will limit our discussion to computer-based virtual reality (VR) simulators. Recent findings A review of the recent literature on TBS revealed very limited application of VR simulators for pre-operative preparation. Current evidence suggests limitations in fidelity preclude successful patient-specific case rehearsal using VR simulation. Further investigation and clinical evaluation are required to validate its use outside of training and skill assessment. Summary This article provides an overview of the current use of VR simulators with emphasis on pre-operative planning. We evaluate the limitations of the technology, and discuss potential areas of improvement for the future. More studies are necessary to assess the value of VR simulation for pre-operative preparation. PMID:26339966

    To evaluate the effectiveness of a psychological preoperative program in reducing preoperative anxiety and in promoting compliance of pediatric participants with surgical procedures. Fifty children and their mothers were subjected to two conditions of treatment to investigate whether psychological preparation activities and psychologist's support during all phases of the operatory iter (group 1) were as efficient in reducing mothers' and child's anxiety and in increasing the child's compliance as distraction activities (group 2). The observed child anxiety was assessed using mYPAS; compliant behaviors with Induction Compliance Checklist; and mothers' anxiety with Amsterdam Pre-operative Anxiety and Information Scale. Children of the first group were less anxious and more cooperative in the preoperative period and during anesthesia induction than in the other condition. The psychological program was also more efficient in reducing mothers' anxiety. Finally, the mothers of group 1 showed a significantly higher satisfaction and judged as significantly more effective the program proposed to prepare their children than the mothers of group 2. Preparing children through playful dramatization of the operative procedure, manipulation of medical instruments and psychologist's support may be useful in pediatric surgery structures. © 2013 Blackwell Publishing Ltd.

    The purpose of the present study was to assess patients' anxiety level and information requirement in the preoperative phase. During routine preoperative screening, 320 patients were asked to assess their anxiety and information requirement on a six-item questionnaire, the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Two hundred patients also completed Spielberger's State-Trait Anxiety Inventory (STAI-State). Patients were able to complete the questionnaire in less than 2 min. On factor analysis, two factors emerged clearly: anxiety and the need for information. The anxiety scale correlated highly (0.74) with the STAI-State. It emerged that 32% of the patients could be considered as "anxiety cases" and over 80% of patients have a positive attitude toward receiving information. Moreover, results demonstrated that 1) women were more anxious that men; 2) patients with a high information requirement also had a high level of anxiety; 3) patients who had never undergone an operation had a higher information requirement than those who had. The APAIS can provide anesthesiologists with a valid, reliable, and easily applicable instrument for assessing the level of patients' preoperative anxiety and the need for information.

    Preoperative anxiety is often expressed by patients requiring filtration surgery for their glaucoma. So far, there has been no scale for screening this group of patients for preoperative anxiety. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) is a self-evaluation questionnaire which has been used in specialties other than ophthalmology and which makes it possible to identify the adult patients with a high level of preoperative anxiety over an upcoming surgical procedure. The purpose of this study is to estimate the preoperative anxiety in glaucoma patients requiring filtration surgery. We performed a prospective study of 36 adult patients with chronic glaucoma not responding to medical treatment and who were about to undergo filtration surgery (trabeculectomy or deep sclerectomy). The APAIS questionnaire was given to the patients after discussing the indication for surgery. A global anxiety score (ranging from 4 to 20) above 10 defined patients with a high level of preoperative anxiety. We attempted to identify among these patients the factors related to filtration surgery which caused them anxiety (lack of control of intraocular pressure, risk of blindness, presence of the filtering bleb). In our sample of patients, we found that glaucoma was a source of anxiety. That was also true for the surgical procedure, though most patients believe that once the decision had been made, their psychological status was not modified by the upcoming procedure. The patient-clinician relationship is important in any chronic disease, all the more so in glaucoma, since this disease remains asymptomatic for a long time. When filtration surgery is necessary, the patients are going to express less preoperative anxiety if they trust their physician and if individualized information has been given to them The French version of the APAIS is a quick scale, easily completed, that can be recommended for evaluating anxiety and patients' need for information prior to filtering

    Unrelieved postoperative pain may impair rehabilitation, compromise functional outcomes, and lead to patient dissatisfaction. Preemptive multimodal analgesic techniques may improve outcomes after surgery. We hypothesized that patients using preoperative cryotherapy plus a standardized postoperative treatment plan will have lower pain scores and require less pain medication compared with patients receiving a standardized postoperative treatment plan alone after arthroscopically assisted anterior cruciate ligament reconstruction (ACLR). A total of 53 consecutive patients undergoing arthroscopically assisted ACLR performed by one of seven surgeons were randomly assigned to one of two groups. Group 1 received no preoperative cryotherapy and group 2 received 30 to 90 minutes of preoperative cryotherapy to the operative leg using a commercial noncompressive cryotherapy unit. Visual analog scale pain scores and narcotic use were recorded for the first 4 days postoperatively. Total hours of cold therapy and continuous passive motion (CPM) use and highest degree of flexion achieved were recorded as well. Group 1 consisted of 26 patients (15 allograft Achilles tendon and 11 autograft bone patellar tendon bone [BPTB]), and group 2 consisted of 27 patients (16 allograft Achilles tendon and 11 autograft BPTB). Group 2 patients reported less pain (average 1.3 units, p < 0.02) and used less narcotic use (average 1.7 tablets, p < 0.02) for the first 36 hours compared with group 1. No statistically significant differences were identified between the two groups with regard to demographics, hours of postoperative cryotherapy, hours of CPM use, or maximum knee flexion achieved. Complications did not occur in either group. This is the first report we are aware of showing the postoperative effects of preoperative cryotherapy. Our results support the safety and efficacy of preoperative cryotherapy in a multimodal pain regimen for patients undergoing ACL reconstruction.

    Purpose. To demonstrate the effectiveness of preoperative and palliative colorectal stent placement in acute colonic obstruction. Methods. Sixty-seven consecutive patients (mean age 67.3 years, range 25-93 years) with clinical and radiological signs of colonic obstruction were treated: 45 (67%) preoperatively and 22 (33%) with a palliative intent. In 59 patients (88%) the obstruction was malignant, while in 8 (12%) it was benign. A total of 73 enteric Wallstents were implanted under combined fluoroscopic/endoscopic guidance. Results. Forty-five patients were treated preoperatively with a technical success rate of 84%, a clinical success rate of 83%, and a complication rate of 16%. Of the 38 patients who were successfully stented preoperatively, 36 (95%) underwent surgery 2-22 days (mean 7.2 days) after stent insertion. The improved general condition and adequate bowel cleansing allowed single-stage tumor resection and primary end-to-end anastomosis without complications in 31 cases (86% of all operations), while only 5 patients had colostomies. Stent placement was used as the final palliative treatment in 22 patients. The technical success rate was 95%, the clinical success rate 72%, and the complication rate relatively high at 67%, caused by reocclusion in most cases. After noninvasive secondary interventions (e.g., tube placement, second stenting, balloon dilatation) the secondary patency of stents was 71% and mean reported survival time after stent insertion was 92 days (range 10-285 days). Conclusion. Preoperative stent placement in acute colonic obstruction is minimally invasive and allows an elective one-stage surgery in most cases. Stent placement also proved a valuable alternative to avoid colostomy in palliation.

    Preoperative venous return (VR) optimization and adequate blood volume is essential in management of morbidly obese patients (MO) in order to avoid perioperative circulatory instability. In this study, all subjects underwent a preoperative 3-week preparation by rapid-weight-loss-diet (RWL) as part of their treatment program for bariatric surgery. This is a prospective, observational study of 34 morbidly obese patients consecutively scheduled for bariatric surgery at Sunderby County Hospital, Luleå, Sweden. Preoperative transthoracic echocardiography (TTE) was performed in the awake state before and after intravascular volume challenge (VC) of 6 ml colloids/kg ideal body weight (IBW). Effects of standardized VC were evaluated by TTE. Dynamic and non-dynamic echocardiographic indices for VC were studied. Volume responsiveness and level of VR before and after VC were assessed by TTE. An increase of stroke volume ≥13% was considered as a volume responder. Twenty-nine out of 34 patients were volume responders. After VC, a majority of patients (23/34) were euvolemic, and only 2/34 were hypovolemic. Post-VC hypervolemia was observed in 9/34 of patients. The IBW-based volume challenge regime was found to be suitable for preoperative rehydration of RWL-prepared MO. Most of the patients were volume responders. Preoperative state of VR was not associated with volume responsiveness. IBW estimates and appropriate monitoring avoids potential hyperhydration in MO. For VC assessment, conventional Doppler indices were found to be more suitable compared to tissue Doppler, giving sufficient information on pressure-volume correlation of the left ventricle in morbidly obese.

    To compare expected and actual renal function after nephrectomy. Nuclear renal scan estimates differential kidney function and is commonly used to calculate expected postoperative renal function after radical nephrectomy. However, the observed postoperative renal function is often different from the expected. A retrospective review was performed on 136 patients who underwent radical nephrectomy or nephroureterectomy and had a preoperative renal scan with calculated differential function. Glomerular filtration rate (GFR) values, preoperative and postoperative, were calculated with the Modification of Diet in Renal Disease (MDRD) equation. The expected postoperative GFR based on renal scan was compared with the actual postoperative GFR. The average age of patients undergoing surgery was 58.6 years, and the indication for surgery was for benign causes in 59 (44%) patients and cancer in 76 (56%) patients. The average preoperative creatinine and estimated GFR were 1.0 mg/dL and 69.9 mL/min/1.73 m(2). At a median follow-up of 3.3 months, the actual postoperative GFR exceeded the expected GFR by an average of 12.1% (interquartile range, 2.6%-25.2%). When stratified by preoperative GFR >90, 60-90, and <60 mL/min/1.73 m(2), respectively, the observed GFR exceeded the expected GFR by 4.3%, 12.6%, and 14.9%, respectively (P = .16). This trend was maintained when GFR was plotted over time. After nephrectomy, the remaining kidney exceeded the expected postoperative GFR by 12% in this cohort of patients with preoperative renal scans. Patients with existing renal insufficiency had the greatest compensatory response, and this was durable over time. Copyright © 2014 Elsevier Inc. All rights reserved.

    Preoperative anxiety has a significant effect on the outcome of anesthesia and surgery. At present, there is no published data on the preoperative anxiety levels in Sri Lankan patients. In the West, several validated questionnaires such as The Amsterdam Preoperative Anxiety and Information Scale (APAIS) and State Trait Anxiety Inventory (STAI) are used. To measure the preoperative anxiety levels in patients using APAIS and to analyze the factors affecting anxiety and the role played by the anesthetist in allaying anxiety. One hundred patients scheduled for elective surgery were prospectively studied using the APAIS. The internal consistency was checked using Cronbach's alpha. The ages varied 25 to 72 years (mean=48.7 years, SD=13.6). Reliability of the APAIS was high; Cronbach's alpha=0.864 in the overall component and 0.84, 0.73 and 0.97 in the anxiety related to surgery, anesthesia and in the information desire components, respectively. Females were more anxious than males (p=0.02) and those who had never sustained surgery were more anxious than those who previously had surgery (p=0.05). An anesthetist's visit and premedication reduced total anxiety scores (Z=-3.07, p=0.002) and anesthesia related anxiety scores (Z=-3.45, p=0.001). The prevalence of anxiety is high among Sri Lankan patients. Females are more anxious than males and those who have never had surgery are more anxious than those who have had surgery. The anesthetist's visit could reduce anxiety. Sinhala version of the APAIS is highly reliable in assessing the preoperative anxiety levels. Copyright © 2012. Published by Elsevier B.V.

    Arteriovenous fistula (AVF) maturation failure is the primary cause of dialysis vascular access dysfunction. To evaluate whether preoperative vascular functional properties predict postoperative AVF measurements, patients enrolled in the Hemodialysis Fistula Maturation Study underwent up to five preoperative vascular function tests (VFTs): flow-mediated dilation (FMD), nitroglycerin-mediated dilation (NMD), carotid-femoral pulse wave velocity, carotid-radial pulse wave velocity, and venous occlusion plethysmography. We used mixed effects multiple regression analyses to relate each preoperative VFT to ultrasound measurements of AVF blood flow rate and venous diameter at 1 day, 2 weeks, and 6 weeks after AVF placement. After controlling for AVF location, preoperative ultrasound measurements, and demographic factors (age, sex, race, and dialysis status), greater NMD associated with greater 6-week AVF blood flow rate and AVF diameter (per absolute 10% difference in NMD: change in blood flow rate =14.0%; 95% confidence interval [95% CI], 3.7% to 25.3%; P<0.01; change in diameter =0.45 mm; 95% CI, 0.25 to 0.65 mm; P<0.001). Greater FMD also associated with greater increases in 6-week AVF blood flow rate and AVF diameter (per absolute 10% difference in FMD: change in blood flow rate =11.6%; 95% CI, 0.6% to 23.9%; P=0.04; change in diameter =0.31 mm; 95% CI, 0.05 to 0.57 mm; P=0.02). None of the remaining VFT parameters exhibited consistent statistically significant relationships with both postoperative AVF blood flow rate and diameter. In conclusion, preoperative NMD and FMD positively associated with changes in 6-week AVF blood flow rate and diameter, suggesting that native functional arterial properties affect AVF development.

    Combinations of transarterial chemoembolization (TACE) and radical therapies (pretransplantation, resection and radiofrequency ablation) for hepatocellular carcinoma (HCC) have been reported as controversial issues in recent years. A consecutive sample of 1560 patients with Barcelona Clinic Liver Cancer (BCLC) stage A/B HCC who underwent solitary Radiofrequency ablation (RFA), resection or liver transplantation (LT) or adjuvant pre-operative TACE were included. The 1-, 3- and 5-year overall survival rates and tumor-free survival rates were comparable between the solitary radical therapy group and TACE combined group in the whole group and in each of the subgroups (RFA, resection and LT) (P > 0.05). In the subgroup analysis, according to BCLC stage A or B, the advantages of adjuvant TACE were also not observed (P > 0.05). A Neutrophil-lymphocyte ratio (NLR) more than 4, multiple tumor targets, BCLC stage B, and poor histological grade were significant contributors to the overall and tumor-free survival rates. In conclusions, our results indicated that preoperative adjuvant TACE did not prolong long-term overall or tumor-free survival, but LT should nevertheless be considered the first choice for BCLC stage A or B HCC patients. Radical therapies should be performed very carefully in BCLC stage B HCC patients.

    Introduction Pre-operative investigations for emergency surgical patients differ between centers. Following established guidelines can reduce unnecessary investigation, cost of treatment and hospital stay. The present audit was carried out to evaluate the condition of doing pre-operative investigations for three common surgical emergencies compared to National Institute for Health and Care Excellence (NICE) guidelines and local criteria. Methods A retrospective clinical audit of acute-appendicitis, abscess and hernia patients admitted to the emergency department was carried out over a one-year period from July 2014 to July 2015. Data of laboratory investigations, their indication, cost and duration of hospital stay was collected and compared with NICE-guidelines. Results A total of 201 patients were admitted to the emergency department during the audit period. These included 77(38.3%) cases of acute-appendicitis, 112 (55.7%) cases of abscesses, and 12 (6%) cases of hernia. Investigations not indicated by NICE-guidelines included 42 (20.9%) full blood counts, 29 (14.4%) random blood sugars, 26 (12.9%) urea tests, 4 (2%) chest x-rays, 13 (6.5%) electrocardiographs, and 58 (28.9%) urine analyses. These cost 25,675 Rupees (245.46 Dollars) in unnecessary investigation costs and 65.7 days of additional hospital stay. Conclusions Unnecessary investigations for emergency surgical patients can be reduced by following NICE-guidelines. This will reduce workload on emergency services, treatment costs and the length of hospital stay. PMID:28286827

    Preoperative anxiety affects patients both physically and psychologically. It may also influence the patient's perioperative experience and result in reduced patient satisfaction with care and potentially delayed recovery. Previous research indicates that patients who listen to music in the perioperative setting experience less anxiety than patients who do not listen to music. Research does not address the duration of music required to effectively reduce anxiety in this population. A randomized control trial was used. Two intervention groups (15-minute music and 30-minute music) and one control group (no music) were compared. Patients (n = 133) demonstrated less anxiety after listening to either 15 or 30 minutes of music (P < .0001). Patients (n = 47) who listened to 15 minutes of music demonstrated less anxiety than those who did not listen to music (P = .005), whereas patients (n = 41) who listened to 30 minutes of music demonstrated less anxiety than those who did not listen to music (P < .001). Listening to as little as 15 minutes of music preoperatively is an effective method to reduce anxiety in patients who are about to have surgery.

    To evaluate the preoperative prevalence of each type of J-wave syndrome electrocardiographic pattern and its association with perioperative cardiac events. Retrospective study. Single hospital university study. The study evaluated 930 patients who underwent gynecologic, abdominal, neurosurgical, orthopedic, and urologic surgeries. Preoperative standard 12-lead electrocardiogram (ECG) monitoring was performed, and each type of J-wave syndrome ECG pattern-types 1, 2, and 3 and Brugada syndrome-type-was evaluated. Incidence of perioperative cardiac events was investigated up to 1 year postoperatively using an electronic medical record system. Data from 789 patients were included in the final study. Of these, 16 patients (2.0%) had J-wave syndrome: 7 patients (0.9%) had type-1 patterns; 5 patients (0.6%) had type-2 patterns; 2 patients (0.3%) had type-3 patterns; and 2 patients (0.3%) had Brugada syndrome-type ECG patterns. A J-point elevation≥0.2 mV, which is considered to be more dangerous, was found in only 2 patients with Brugada syndrome-type ECG patterns, both of whom suffered perioperative lethal arrhythmias. Patients with J-wave syndrome ECG patterns, even dangerous patterns, are not necessarily associated with a higher risk of perioperative cardiac events. However, Brugada syndrome type ECG patterns should be carefully monitored. Copyright © 2015 Elsevier Inc. All rights reserved.

    Combinations of transarterial chemoembolization (TACE) and radical therapies (pretransplantation, resection and radiofrequency ablation) for hepatocellular carcinoma (HCC) have been reported as controversial issues in recent years. A consecutive sample of 1560 patients with Barcelona Clinic Liver Cancer (BCLC) stage A/B HCC who underwent solitary Radiofrequency ablation (RFA), resection or liver transplantation (LT) or adjuvant pre-operative TACE were included. The 1-, 3- and 5-year overall survival rates and tumor-free survival rates were comparable between the solitary radical therapy group and TACE combined group in the whole group and in each of the subgroups (RFA, resection and LT) (P > 0.05). In the subgroup analysis, according to BCLC stage A or B, the advantages of adjuvant TACE were also not observed (P > 0.05). A Neutrophil-lymphocyte ratio (NLR) more than 4, multiple tumor targets, BCLC stage B, and poor histological grade were significant contributors to the overall and tumor-free survival rates. In conclusions, our results indicated that preoperative adjuvant TACE did not prolong long-term overall or tumor-free survival, but LT should nevertheless be considered the first choice for BCLC stage A or B HCC patients. Radical therapies should be performed very carefully in BCLC stage B HCC patients. PMID:28155861

    Background and Aims: Pre-operative investigations are performed before any surgical intervention under anaesthesia. Many are considered as routine. However, there are no clear guidelines regarding these in India. We aim to look at the relevance of the laboratory investigations ordered routinely and their cost implications compared with the National Institute of Clinical Excellence (NICE) guidelines. Methods: This prospective study was carried out at a tertiary care hospital. A total of 163 patients scheduled for elective surgical procedures were included in this study. Neither the surgeons nor anaesthesiologists involved in the case were aware of the study. The laboratory investigations of the patients who underwent surgery were noted. All values were categorised as normal or abnormal and they were assessed as indicated or unindicated based on NICE guidelines. Results: One hundred and sixty-three patients were subjected to a total of 984 tests. Forty three patients (26%) were subjected to tests as per NICE guidelines. Of the 984 tests, 515 tests were unindicated (52%). Out of the 515 unindicated tests, 7 (1.3%) were abnormal. None of these seven tests required any intervention or change of anaesthetic plan. The most common unindicated tests done were cardiac echocardiography and chest X-ray (92.5% and 93% respectively). The additional cost incurred towards unindicated tests was 63% of the total cost for the tests. Conclusion: Pre-operative laboratory investigations add to cost significantly. Patient premorbid conditions and surgical grade should guide the clinician to request for the relevant laboratory tests. PMID:27942058

    Aim: To investigate the possible effects of preoperative oral Midazolam on parental separation anxiety, emergence delirium, and post-anesthesia care unit time on children undergoing dental rehabilitation under general anesthesia. Methods: Randomized, prospective, double-blind study. Seventy-eight American Society of Anesthesiology (ASA) I children were divided into two groups of 39 each. Children of the first group were premedicated with oral Midazolam 0.5 mg/kg, while children of the control group were premedicated with a placebo. Scores for parental separation, mask acceptance, postoperative emergence delirium, and time spent in the post-anesthesia care unit were compared statistically. Results: The test group showed significantly lower parental separation scores and high acceptance rate for anesthetic mask. There was no significant difference between the two groups regarding emergence delirium and time spent in post-anesthesia care unit. Conclusions: Preoperative oral Midazolam could be a useful adjunct in anxiety management for children suffering dental anxiety. The drug may not reduce the incidence of postoperative emergence delirium. The suggested dose does not seem to affect the post-anesthesia care unit time. PMID:25992332

    In recent years, the continuous noninvasive hemoglobin measurement has been offered by devices using advanced pulse oximetry technology. Accuracy has been established in healthy adults as well as in surgical and intensive care unit patients but not in the setting of acute hemorrhage. In this study, we evaluated the accuracy of such a device in the clinical setting of preoperative phlebotomy thereby mimicking a scenario of acute blood loss. This prospective study included patients undergoing surgical repair of congenital heart disease (CHD) for whom preoperative phlebotomy was planned. Blood was removed after the induction of anesthesia and prior to the start of the surgical procedure. Replacement with crystalloid was guided by hemodynamic variables and cerebral oxygenation measured by near-infrared spectroscopy. Hemoglobin was measured by bedside whole blood analysis (total hemoglobin [tHb]) before and after phlebotomy, and concurrent measurements from the pulse co-oximeter (noninvasive, continuous, or spot-check testing of total hemoglobin [SpHb]) were recorded. The study cohort included 45 patients ranging in age from 3 months to 50 years. Preoperative phlebotomy removed an average of 9.2 mL/kg of blood that was replaced with an average of 7.2 mL/kg of crystalloid. The pre- and postphlebotomy tHb values were 13.0 ± 1.9 and 12.4 ± 1.8 g/dL, respectively. The absolute difference between the tHb and SpHb (▵Hb) was 1.2 ± 0.1 g/dL. Bland-Altman analysis revealed a bias of 0.1 g/dL, a precision of 1.5 g/dL, and 95% limits of agreement of -2.8 to 3.1 g/dL. In 52.2% of the sample sets, the SpHb was within 1 g/dL of the actual hemoglobin value (tHb), and in 80% of the sample sets, the SpHb was within 2 g/dL. No variation in the accuracy of the deviation was noted based on the patient's age, weight, or type of CHD (cyanotic versus acyanotic). The current study demonstrates that the accuracy of continuous, noninvasive hemoglobin measurement was not affected by acute

  10. Augmenting intraoperative ultrasound with preoperative magnetic resonance planning models for percutaneous renal access

    PubMed Central

    2012-01-01

    Background Ultrasound (US) is a commonly-used intraoperative imaging modality for guiding percutaneous renal access (PRA). However, the anatomy identification and target localization abilities of the US imaging are limited. This paper evaluates the feasibility and efficiency of a proposed image-guided PRA by augmenting the intraoperative US with preoperative magnetic resonance (MR) planning models. Methods First, a preoperative surgical planning approach is presented to define an optimal needle trajectory using MR volume data. Then, a MR to US registration is proposed to transfer the preoperative planning into the intraoperative context. The proposed registration makes use of orthogonal US slices to avoid local minima while reduce processing time. During the registration, a respiratory gating method is used to minimize the impact of kidney deformation. By augmenting the intraoperative US with preoperative MR models and a virtual needle, a visual guidance is provided to guarantee the correct execution of the surgical planning. The accuracy, robustness and processing time of the proposed registration were evaluated by four urologists on human data from four volunteers. Furthermore, the PRA experiments were performed by the same four urologists on a kidney phantom. The puncture accuracy in terms of the needle-target distance was measured, while the perceptual quality in using the proposed image guidance was evaluated according to custom scoring method. Results The mean registration accuracy in terms of the root mean square (RMS) target registration error (TRE) is 3.53 mm. The RMS distance from the registered feature points to their average is 0.81 mm. The mean operating time of the registration is 6'4". In the phantom evaluation, the mean needle-target distance is 2.08 mm for the left lesion and 1.85 mm for the right one. The mean duration for all phantom PRA tests was 4'26".

    OBJECTIVE Patient satisfaction is a commonly used metric in the current health care environment. While factors that affect patient satisfaction following spine surgery are complex, the authors of this study hypothesized that specific diagnostic groups of patients are more likely to be satisfied after spine surgery and that this is reflected in patient-reported outcome measures. The purpose of this study was to determine if the preoperative diagnosis-disc herniation, stenosis, spondylolisthesis, adjacent segment degeneration, or mechanical disc collapse-would impact patient satisfaction following surgery. METHODS Patients enrolled in the Quality Outcomes Database, formerly known as the National Neurosurgery Quality and Outcomes Database (N(2)QOD), completed patient-reported outcome measures, including the Oswestry Disability Index (ODI) and Numeric Rating Scale (NRS) for back pain (NRS-BP) and leg pain (NRS-LP) preoperatively and 1-year postoperatively. Patients were stratified by diagnosis and by their response to the satisfaction question: 1) surgery met my expectations; 2) I did not improve as much as I hoped, but I would undergo the same operation for the same results; 3) surgery helped, but I would not undergo the same operation for the same results; or 4) I am the same or worse as compared with before surgery. RESULTS A greater proportion of patients with primary disc herniation or spondylolisthesis reported that surgery met expectations (66% and 67%, respectively), followed by recurrent disc herniation and stenosis (59% and 60%, respectively). A smaller proportion of patients who underwent surgery for adjacent segment degeneration or mechanical disc collapse had their expectations met (48% and 41%, respectively). The percentage of patients that would undergo the same surgery again, by diagnostic group, was as follows: disc herniation 88%, recurrent disc herniation 79%, spondylolisthesis 86%, stenosis 82%, adjacent segment disease 75%, and mechanical collapse

    Safe and effective patient preoperative skin antisepsis is recommended to prevent surgical site infections (SSIs), reduce patient morbidity, and reduce systemic costs. However, there is lack of consensus among best practice recommendations regarding the optimal skin antiseptic solution and method of application. In 2010 and 2011 the health technology appraisal committee of the Surgery Operational Clinical Network (SOCN), of Alberta Health Services (AHS), conducted an environmental scan to determine the current preoperative skin antisepsis in Alberta, reviewed key publications and existing guidelines, and requested a systematic review from the Canadian Agency for Drugs and Technologies in Health (CADTH). Using this information, and an established protocol for evidence-informed recommendations, the health technology appraisal committee made recommendations that were, in 2012, reviewed and endorsed by the SOCN executive and the AHS-Infection Prevention and Control (IPC) group. The environmental scan revealed practice variation in the types of antiseptic solutions and application methods being used in the 18 Alberta hospitals surveyed. The systematic review suggested that preoperative antiseptic showering reduces skin flora but the effect on SSI rates was inconclusive. While the review found no conclusive evidence to recommend an optimal antiseptic solution or application method, the results of two large randomized controlled trials suggest that chlorhexidine in 70% alcohol is more effective than povidone iodine in the prevention of SSIs. These results and the recommendations from Safer Healthcare Now!, a program of the Canadian Patient Safety Institute (CPSI), were used to inform the recommendations for AHS. These recommendations included abandoning preoperative showering with antiseptics except for special cases (high-risk surgeries such as sternotomies and implants as recommended by IPC) and standardizing skin antiseptic application methods and solution to

    Knee osteoarthritis (OA) is a leading cause of disability in older adults (≥60) in the UK. If nonsurgical management fails and if OA severity becomes too great, knee arthroplasty is a preferred treatment choice. Preoperative physiotherapy is often offered as part of rehabilitation to improve postoperative patient-based outcomes. Systematically review whether preoperative physiotherapy improves postoperative, patient-based outcomes in older adults who have undergone total knee arthroplasty (TKA) and compare study interventions to best-practice guidelines. A literature search of Randomized Controlled Trials (RCTs), published April 2004-April 2014, was performed across six databases. Individual studies were evaluated for quality using the PEDro Scale. Ten RCTs met the full inclusion/exclusion criteria. RCTs compared control groups versus: preoperative exercise (n = 5); combined exercise and education (n = 2); combined exercise and acupuncture (n = 1); neuromuscular electrical stimulation (NMES; n = 1); and acupuncture versus exercise (n = 1). RCTs recorded many patient-based outcomes including knee strength, ambulation, and pain. Minimal evidence is presented that preoperative physiotherapy is more effective than no physiotherapy or usual care. PEDro Scale and critical appraisal highlighted substantial methodological quality issues within the RCTs. There is insufficient quality evidence to support the efficacy of preoperative physiotherapy in older adults who undergo total knee arthroplasty.

  14. Preoperative regional cerebral oxygen saturation is a predictor of postoperative delirium in on-pump cardiac surgery patients: a prospective observational trial

    PubMed Central

    2011-01-01

    Introduction Postoperative delirium is an important problem in patients undergoing major surgery. Cerebral oximetry is a non-invasive method to detect imbalances in the cerebral oxygen supply/demand-ratio. Low preoperative cerebral oxygen saturation (ScO2) levels have been associated with postoperative delirium in non-cardiac surgery patients. The present prospective observational study determines the relationship between pre- and intra-operative ScO2 levels and postoperative delirium in patients undergoing on-pump cardiac surgery. Methods After approval of the local ethical committee and written informed consent, N = 231 patients scheduled for elective/urgent cardiac surgery were enrolled. Delirium was assessed by the confusion-assessment-method for the intensive care unit (CAM-ICU) on the first three days after surgery. ScO2 was obtained on the day before surgery, immediately before surgery and throughout the surgical procedure. Preoperative cognitive function, demographic, surgery related, and intra- and post-operative physiological data were registered. Results Patients with delirium had lower pre- and intra-operative ScO2 readings, were older, had lower mini-mental-status-examination(MMSE) scores, higher additive EuroScore and lower preoperative haemoglobin-levels. The binary logistic regression identified older age, lower MMSE, neurological or psychiatric disease and lower preoperative ScO2 as independent predictors of postoperative delirium. Conclusions The presented study shows that a low preoperative ScO2 is associated with postoperative delirium after on-pump cardiac surgery. PMID:21929765

    Kalantar-Hormozi, A J; Davami, Babak

    2005-08-01

    The development of antisepsis in the late nineteenth and early twentieth centuries revolutionized health care. The time-honored technique of skin preparation is to scrub the entire operative area of the patient for 5 to 7 minutes with a germicidal detergent solution and then paint the region with an antimicrobial solution of either tincture of povidone-iodine (Betadine) or chlorhexidine. Although antiseptics result in lower colony counts on the skin, they have side effects and higher cost in relation to normal saline. The authors have prepared patients by showering the surgical site with soap and water and rinsing it with normal saline, in 905 cases of outpatient, clean-wound plastic surgery. In another 905 cases that served as the control group, the traditional method of preoperative shower and scrub with chlorhexidine or Betadine was used. In both groups, there was no incidence of wound infection.

    Research on bilinguals with brain lesions is complicated by high patient variability, making it difficult to find well-matched controls. We benefitted from a database of over 700 patients and conducted an analysis of pre-operative functional magnetic resonance imaging data to assess language dominance in 25 early, highly proficient Spanish-English bilinguals, and 25 carefully matched monolingual controls. Our results showed that early bilingualism is associated with greater bilateral hemispheric involvement, and monolingualism is associated with stronger left hemisphere lateralization (p=0.009). The bilinguals showed more pronounced right hemisphere activation (p=0.008). Although language dominance values were concordant in the bilingual group, there were a few (12%) atypical cases with different lateralization patterns in L1 and L2. Finally, we found distinct areas of activity in first and second language within the language network, in addition to regions of convergence. These data underscore the need to map all languages proficiently spoken by surgical candidates.

    The Helsinki Declaration offers guidelines for the warranty and improvement of patient safety in Anaesthesiology. The assessment of elective patients and their preoperative optimization plays a key role herein. Individual risk factors and preexisting pathologies have to be identified in order to initiate specific pre- and aftercare and an appropriate monitoring. The measures need to be evidence-based, goal-oriented and efficient. Our recommendations aim at elective adult patients planned for non-cardiac and non-lung-resecting surgery and stress the importance of gathering information from patients, performing physical examinations and arranging further diagnostic customized upon these findings only in contrast to routine testing. They shall spark the formulation or improvement of center-based, interdisciplinary standards of procedure in order to fulfill our great responsibility for the perioperative care of our patients.

    2012-09-01

    The purpose of this study was to evaluate the usefulness of magnetic resonance imaging (MRI) in detecting elbow articular cartilage injuries through comparison of preoperative MRI and magnetic resonance arthrography (MRA) with arthroscopic findings. Retrospective case analysis. Tertiary care orthopedic private practice. Consecutive series of 31 patients presenting with elbow pain and diagnosed at arthroscopy with articular cartilage defects of the elbow. All patients had a preoperative MRI or MRA using a 1.5 T magnet. Each patient had a systematic elbow arthroscopy, with careful inspection and recording of chondral injuries in 4 anatomical regions: capitellum, radius, trochlea, and ulna. Each MRI/MRA was then independently reviewed by 2 radiologists blinded to the arthroscopic findings. The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy were calculated for MRI and MRI compared with arthroscopy as the gold standard, for each of the anatomical regions. The accuracy of MRI was 45% for chondral injuries of the radius, 65% for the capitellum, 20% for the ulna, and 30% for the trochlea. The accuracy of MRA was 45% for chondral injuries of the radius, 64% for the capitellum, 18% for the ulna, and 27% for the trochlea. We conclude that the ability of MRI and MRA using a 1.5 T magnet to detect articular cartilage lesions is limited. Neither MRI nor MRA demonstrates the intraarticular surface as accurately as direct visualization with the arthroscopy. This may be improved with the use of 3 T MRI. This study demonstrates that MRI and MRA with a 1.5 T magnet, as used in community practice, have limited ability to detect cartilage lesions of the elbow.

    2008-02-01

    Three cases of fibroadenoma associated with carcinoma are reported. These cases were diagnosed within a screening programme as a result of suspicious mammographic findings, and the diagnosis of malignancy was confirmed preoperatively by core biopsy in all cases. The mammographic findings suggestive of carcinoma within fibroadenoma were irregularity of margins in one case and associated new suspicious pleomorphic and linear calcifications in the two other cases. The preoperative diagnosis of carcinoma within fibroadenoma was provided by ultrasound-guided core biopsy in two cases and core biopsy under stereotactic guidance in one case. Whereas asymptomatic fibroadenoma with benign imaging appearances usually does not require further investigation, fibroadenoma with atypical imaging features requires a triple test investigation.

    A rhinoplasty in Asians differs from a rhinoplasty performed in patients of other ethnicities. Surgeons should understand the concept of Asian beauty, the nasal anatomy of Asians, and common problems encountered while operating on the Asian nose. With this understanding, surgeons can set appropriate goals, choose proper operative procedures, and provide an outcome that satisfies patients. In this article the authors define the concept of an Asian rhinoplasty—a paradigm shift from the traditional on-top augmentation rhinoplasty to a structurally integrated augmentation rhinoplasty—and provide a step-by-step procedure for the use of Adobe Photoshop as a preoperative program to simulate the expected surgical outcome for patients and to develop a preoperative plan for surgeons.

    The idea of the preoperative anesthesia clinic as a means of examining and treating the patient so that he will arrive in the operating theater as strong and healthy as possible is well established in practice and literature.However, problems in clinic design and execution often result in high patient waiting times, decreased patient and staff satisfaction, decreased patient capacity, and high clinic costs. Although the details of clinic design, outcomes, and satisfaction have been extensively evaluated at civilian hospitals, we have not found corresponding literature addressing these issues specifically within military preoperative evaluation clinics. We find that changing to an appointment-based (versus walk-in) system and eliminating data collection step redundancies will likely result in lower wait times, higher satisfaction, lower per patient costs, and a more streamlined and resource-efficient structure.

    Abstract We describe a 48-year-old man with cholecystolithiasis whose preoperative magnetic resonance cholangiopancreatography (MRCP) scan showed that the right accessory hepatic duct branching from the cystic duct dominated an anterior segment of the right hepatic lobe. We observed the right accessory hepatic duct using intraoperative cholangiography, and we were able to perform laparoscopic cholecystectomy without injuring it. He had no complication after discharge, and a drip-infusion cholangiography-computed tomography (DIC-CT) scan demonstrated that the right accessory hepatic duct was intact, and it dominated an anterior segment of the right hepatic lobe. During laparoscopic cholecystectomy, a bile duct injury is the most challenging perioperative complication. We selected MRCP preoperatively; however, if it is necessary for us to observe an anomalous biliary tract more precisely, we recommend selecting DIC-CT endoscopic retrograde cholangiopancreatography. Additionally, we think a bile duct injury can be avoided with intraoperative cholangiography, even if there is an anomalous biliary tract. PMID:28702164

  5. Identifying and assessing anxiety in pre-operative patients.

    PubMed

    Pritchard, Michael John

    Increasing demands for hospitals to be more efficient mean that patients attending for an operation are generally admitted on the day of surgery. As a result, healthcare professionals have little time to talk to the patient to ascertain his or her wellbeing, to check for any signs of anxiety and ask whether the patient requires further information about the forthcoming procedure. Healthcare professionals should be encouraged to use appropriate interventions to identify and assess anxious patients. There are several instruments available to measure the patient's level of pre-operative anxiety. This article reviews the Amsterdam Preoperative Anxiety and Information Scale, which is easy for patients to complete and may help to identify which individuals need extra support.

    Primary fallopian tube carcinoma is a rare clinical entity that constitutes a diagnostic challenge in gynecological practice. Patients generally suffer from the three symptoms: vaginal bleeding, pelvic pain, and vaginal discharge; however, this is usually not sufficient for confirming the diagnosis preoperatively in most circumstances. In this case report, we present a 49-year-old woman whose cervical smear raised a suspicion for fallopian tube carcinoma. All preoperative examination measures such as ultrasonography, hysteroscopy, and endometrial aspiration were normal. Repeated cervical smears were consistent with adenocarcinoma presumably ensourcing from the fallopian tube. The patient underwent laparatomy,total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic para-aortic lymph node dissection. The primary serous papillary adenocarcinoma of the right fallopian tube was detected at the histopathological analysis, and the patient was referred for adjuvant chemotherapy. Cervical smear findings can be the only clue for the diagnosis of fallopian tube carcinoma.

    This article reports on a consecutive series of 3627 breast cancer (BC) patients undergoing preoperative staging by chest x-ray (CXR), bone x-ray (BXR) or bone scintigraphy (BS), and liver ecography (LE) or liver scintigraphy (LS). The detection rate (DR) of preclinical asymptomatic distant metastases depended on the T and N category (TNM classification system), and was very low (CXR: 0.30%, BXR: 0.64%, BS: 0.90%, LE: 0.24%, LS: 0.23%). The sensitivity, determined after a 6-month follow-up, was below 0.50% for all tests. The highest value (0.48%) was recorded for BS, which also had the lowest specificity (0.95%). The entire preoperative staging policy using the studied tests seems questionable due to poor sensitivity and an extremely low DR of distant metastases.

    Professional practice evaluation of anaesthesiologist for high cardiac-risk patient cares in non-cardiac surgery, and assess disparities between results and recommendations. Since June to September 2011, a self-questionnaire was sent to 5000 anesthesiologist. They were considered to be representative of national anesthesiology practitioner. Different items investigated concerned: demography, preoperative cardiac-risk assessment, modalities of specialized cardiologic advice, per- and postoperative care, and finally knowledge of current recommendations. We collected 1255 questionnaire, that is to say 25% of answers. Men were 73%, 38% were employed by public hospital; 70% worked in a shared operating theatre with a general activity. With regards to preoperative assessment, 85% of anaesthetists referred high cardiac-risk patient to a cardiologist. In only 16% of answer, Lee's score appeared in anaesthesia file to assess perioperative cardiac-risk. Only 61% considered the six necessary items to optimal estimate of cardiac-risk. On the other hand, 91% measured routinely the exercise capacities by interrogation. The most frequently doing exam (49% of anaesthetist) was an electrocardiogram in elderly patient. In 96% of case, beta-blockers were given in premedication if they were usually thought. Clopidogrel was stopped by 62% of anesthetist before surgery. In this case, 38% used another medication to take over from this one. Only 7% considered revascularization in coronary patient who were effectively treated. POISE study was know by 40% of practitioner, and 18% estimated that they have changed their practice. Preoperatively, 21% organized multidisciplinary approach for high-risk patient. During surgery, 63% monitored the ST-segment. In postoperative period for cardiac-risk patient, only 11% prescribed systematically an ECG, a troponin dosage, a postoperative monitoring of ST-segment, a cardiologic advice. In case of moderate troponin elevation, they were 70% to realize at

    Preoperative imatinib mesylate (IM) treatment has not yet been standardized. Here, we aim to further explore such therapy on patients with gastrointestinal stromal tumors (GIST) retrospectively. Patients experiencing preoperative IM were identified from January 2009 to February 2015. A total of 28 GIST patients were identified. The patients received preoperative IM treatment for a median length of 13.5 months, ranging from 5 to 37 months. PR and SD were observed in 24 (85.7%) and 4 (15.3%) patients, respectively. The tumor shrinkage occurred predominantly within 6 to 12 months, and slight tumor shrinkage could be observed after 12 months in certain patients. Nineteen patients (67.9%) received surgery, and R0 resection was acquired in 18 (94.7%) patients. The initial mean maximum diameter was 10.5 (5.2 to 19.0) cm and decreased to 5.9 (2.7 to 19.0) cm after preoperative treatment with a median length of 12 (ranging from 5 to 36) months (P < 0.001) in patients receiving operations. Three in 7 cases of rectum GIST underwent abdominoperineal resection, and four others adopted sphincter-sparing resection. Partial gastrectomy was performed in four patients. IM prior to surgery can effectively prevent tumor rupture and facilitate surgery with low surgical morbidity for GIST patients. Tumor shrinkage following IM occurred predominantly within 6 to 12 months, and slight tumor shrinkage could be observed after 12 months in certain patients. In selected patients, prolonged exposure to IM is seemingly advisable under close radiological surveillance.

    We describe the case of a three-week-old female, who presented with fever and swelling of the left thigh. Initial examination revealed signs of infection in both hips, which was confirmed at surgery. However, as the child did not recover despite relevant antibiotics, a full body MRI was performed, revealing multiple abscesses, some of which had to be managed surgically. We emphasize the benefit of MRI as part of the preoperative assessment of multifocal musculoskeletal infections in children.

    Cefazolin remains the preferred preoperative antibiotic for the majority of surgical procedures. However, outcome evidence supporting current dosing recommendations for pre-operative prophylaxis is scarce, particularly for obese patients. With more than 33% of adults in the United States classified as obese, it is crucial that we determine the correct dosing regimen in order to maximize the potential to prevent surgical site infections (SSIs). The purpose of this study was to evaluate whether surgical prophylaxis with cefazolin 2 g, as recommended by practice guidelines, is as effective in preventing SSIs in obese as compared to non-obese patients. In retrospective fashion, data were collected from the electronic medical records of patients who received 2 g of cefazolin preoperatively during a 13-mo period. Patients who met the inclusion criteria were allocated to an obese (n=99) and non-obese (n=96) group according to body mass index (BMI). Charts were reviewed for identification of SSIs as defined by the U.S. Centers for Disease Control and Prevention. For the primary outcome, the numbers of SSIs in the two groups were compared using the Pearson χ(2) test. Patient characteristics were similar in the two groups with the expected exception of weight (mean 90 vs. 110 kg; p<0.001) and BMI (27 vs. 35 kg/m(2); p<0.001). The highest patient weight was 182 kg with a BMI of 55 kg/m(2). The most common surgical service was orthopedics/hand, accounting for 35% of patients. No significant difference was found in the number of SSIs in the two groups (7 vs. 5; p=0.56). No differences between weight and BMI were seen in patients with or without a SSI. Obese patients may continue to receive 2 g of cefazolin preoperatively until large-scale controlled trials show differently.

    To investigate the influence of preoperative antiglaucoma medications on trabeculectomy outcome. Two hundred fifteen eyes, which underwent primary trabeculectomy, were retrospectively analyzed. The average follow-up was 39.8±30.3 months. The only cases of primary open-angle glaucoma, with or without pseudoexfoliation (PXF), were included. "Complete success" was defined as intraocular pressure (IOP) <18 mmHg without glaucoma medications, whereas relative success was defined as the same IOP target with medications. The influence of the preoperatively used glaucoma medications on surgical success was analyzed by univariate Pearson correlation and multivariate (ordinal) regression analysis. There were 118 male (54.9%) and 97 female (45.1%) patients with a mean age of 66.9±9.3 years. PXF glaucoma (PXFG) was present in 93 eyes (43.3%). In 33 patients (15.3%), diabetes mellitus (DM) was present. Complete success was achieved in 116 eyes (54%), relative success in 81 eyes (37.6%), and failure in 18 eyes (8.4%). Neither the total number nor the duration of glaucoma medications used before trabeculectomy was found to have any statistically significant influence on surgical success. In statistical analysis, a combination of topical beta-blocker and carbonic anhydrase inhibitor (BB+CAI) used before surgery was found to be associated with statistically better outcome, whereas the preoperative use of topical beta-blockers alone could have a negative influence on success. PXF was shown to be independently associated with trabeculectomy outcome on multivariate regression analysis. The glaucoma medications used preoperatively were not found to have any statistically significant negative influence on the trabeculectomy outcome and use of the combined BB+CAI preparation could have a positive influence, whereas the use of topical beta-blockers alone could have a negative influence on success, although not statistically significant. The presence of PXF was independently associated

    The purpose of this study was to evaluate the benefits of preoperative embolisation with an absorbable gelatine sponge in selected intracranial meningiomas. We performed a retrospective study of a series of 33 patients who had undergone surgery for meningiomas with a diameter of over 4 cm between the years 2000 and 2007. Two groups were analysed: group A (n = 16) with preoperative embolisation and group B (n = 17) without it. Eligibility criteria for embolisation were: exclusive or predominant irrigation through the external carotid artery, high tumour flow and pronounced vascularisation through the pial branches. The location of the lesion was evaluated preoperatively; blood losses, number of units of blood transfused, surgery time and surgeon's opinion were evaluated intraoperatively. A statistically significant difference was found between the group of embolised patients and those who had not been embolised as far as surgery time (217.5 +/- 69.61 versus 291.76 +/- 56.94 min; p =< 0.002) and blood loss (613.75 +/- 231.42 versus 987.65 +/- 206.68 mL; p => 0.001) were concerned. A positive coloration (r = 0.568; p = 0.001) was found between surgery time and blood loss. No statistically significant relation was observed between age and the number of units of blood transfused. Embolisation was considered to be beneficial by 75% of surgeons. Preoperative embolisation with an absorbable gelatine sponge in patients with intracranial meningiomas with a diameter above 4 cm and exclusive or predominant irrigation by the external carotid artery is effective and safe; it also reduces intraoperative bleeding and surgery time.

    The prognostic implications of preoperative hypernatremia are unknown. We sought to determine whether preoperative hypernatremia is a predictor of 30-day perioperative morbidity and mortality. We conducted a cohort study using the American College of Surgeons-National Surgical Quality Improvement Program and identified 908,869 adult patients undergoing major surgery from approximately 300 hospitals from the years 2005 to 2010. We followed the patients for 30-day perioperative outcomes, which included death, major coronary events, wound infections, pneumonia, and venous thromboembolism. Multivariable logistic regression was used to estimate the odds of 30-day perioperative outcomes. The 20,029 patients (2.2%) with preoperative hypernatremia (>144 mmol/L) were compared with the 888,840 patients with a normal baseline sodium (135-144 mmol/L). Hypernatremia was associated with a higher odds for 30-day mortality (5.2% vs 1.3%; adjusted odds ratio [aOR], 1.44; 95% confidence interval [CI], 1.33-1.56), and this finding was consistent in all subgroups. The odds increased according to the severity of hypernatremia (P < .001 for pairwise comparison for mild [145-148 mmol/L] vs severe [>148 mmol/L] categories). Furthermore, hypernatremia was associated with a greater odds for perioperative major coronary events (1.6% vs 0.7%; aOR, 1.16; 95% CI, 1.03-1.32), pneumonia (3.4% vs 1.5%; aOR, 1.23; 95% CI, 1.13-1.34), and venous thromboembolism (1.8% vs 0.9%; OR, 1.28; 95% CI, 1.14-1.42). Preoperative hypernatremia is associated with increased perioperative 30-day morbidity and mortality. Copyright © 2013 Elsevier Inc. All rights reserved.

  17. Cervical disk arthroplasty versus ACDF for preoperative reducible kyphosis.

    Cervical total disk arthroplasty has proven to be an effective and safe alternative for anterior cervical diskectomy and fusion (ACDF) for the treatment of cervical disk degenerative disease. However, whether and when cervical disk arthroplasty is indicated for preoperative cervical spine kyphosis is unclear. In the authors' clinical experiences, preoperative kyphosis can generally be divided into reducible and irreducible forms according to the results of dynamic flexion-extension lateral radiographs. Reducible kyphosis is mostly related to local disk prolapse, clinical symptoms, and musculature weakness, but irreducible kyphosis is always associated with significant cervical degeneration or congenital bone malformation. In this study, 32 patients with preoperative reducible kyphosis were randomized in a 1:1 ratio to either single-level total cervical arthroplasty with the Discover cervical disk prosthesis (DePuy Spine, Raynham, Massachusetts) (arthroplasty group) or single-level ACDF with a polyetheretherketone cage and plate (ACDF group). No significant differences existed in clinical and radiological results at 2-year follow-up between the arthroplasty and ACDF groups. The global and functional spinal unit angles of the arthroplasty group were significantly lower than those of the ACDF group 6 months postoperatively, which was consistent with the result of the comparison in Neck Disability Index score. However, the sagittal alignment of the overall cervical spine and the treated segment and the Neck Disability Index score significantly improved after 6 months in the arthroplasty group but not in the ACDF group. Therefore, preoperative reducible kyphosis is not a contraindication for cervical total disk arthroplasty. However, neck strength-building exercises should be emphasized for the postoperative rehabilitation after cervical total disk arthroplasty.

    Intramural gastric abscess is a rare condition representing a localized form of suppurative gastritis, which was described in the time of Galen. Cases are usually diagnosed either with a combination of imaging modalities such as upper gastrointestinal series, ultrasound, computed tomography (CT), and endoscopic ultrasound or in conjunction with endoscopy and laparotomy. The authors describe a case of intramural gastric abscess in which the diagnosis was made preoperatively using axial, coronal, and sagittal reformations obtained with multidetector CT.

    Abstract Purpose: To describe the clinical, imaging, and pathologic characteristics and diagnostic methods of telangiectatic osteosarcoma (TOS) for improving the diagnostic level. Materials and methods: The authors retrospectively reviewed patient demographics, serum alkaline phosphatase (AKP) levels, preoperative biopsy pathologic reports, pathologic materials, imaging findings, and treatment outcomes from 26 patients with TOS. Patient images from radiography (26 cases) and magnetic resonance (MR) imaging (22 cases) were evaluated by 3 authors in consensus for intrinsic characteristics. There were 15 male and 11 female patients in the study, with an age of 9–32 years (mean age 15.9 years). Results: Eighteen of 26 patients died of lung metastases within 5 years of follow-up. The distal femur was affected more commonly (14 cases, 53.8%). Regarding serum AKP, normal (8 cases) or mildly elevated (18 cases) levels were found before preoperative chemotherapy. Radiographs showed geographic bone lysis without sclerotic margin (26 cases), cortical destruction (26 cases), periosteal new bone formation (24 cases), soft-tissue mass (23 cases), and matrix mineralization (4 cases). The aggressive radiographic features of TOS simulated the appearance of conventional high-grade intramedullary osteosarcoma, though different from aneurysmal bone cyst. MR images demonstrated multiple big (16 cases) or small (6 cases) cystic spaces, fluid-fluid levels (14 cases), soft-tissue mass (22 cases), and thick peripheral and septal enhancement (22 cases). Nine of 26 cases were misdiagnosed as aneurysmal bone cysts by preoperative core-needle biopsy, owing to the absence of viable high-grade sarcomatous cells in the small tissue samples. Conclusion: The aggressive growth pattern with occasional matrix mineralization, and multiple big or small fluid-filled cavities with thick peripheral, septal, and nodular tissue surrounding the fluid-filled cavities are characteristic imaging features of

    Summary Background Long-term survival in patients with esophageal cancer remains dismal despite the recent improvements in surgery, the advances in radiotherapy (RT) technology, and the refinement of systemic treatments, including the advent of targeted therapies. Although surgery constitutes the treatment of choice for early-stage disease (stage I), a multimodal approach, including preoperative or definitive chemoradiotherapy (CRT) and perioperative chemotherapy, is commonly pursued in patients with locally advanced disease. Methods A review of the literature was performed to assess the role of RT, alone or in combination with chemotherapy, in the management of esophageal cancer. Results Evidence from large, randomized phase III trials and meta-analyses supports the application of perioperative chemotherapy alone or preoperative concurrent CRT in patients with lower esophageal and esophagogastric junction adenocarcinomas. Preoperative CRT but not preoperative chemotherapy alone is now routinely used in patients with locally advanced squamous cell carcinoma (SCC). Additionally, definitive CRT without surgery has also emerged as a valuable approach in the management of resectable esophageal SCC to avoid surgery-related morbidity and mortality, whereas salvage surgery is reserved for those with persistent disease. Furthermore, brachytherapy offers a valuable option in the palliative treatment of patients with locally advanced, unresponsive disease. Fluorodeoxyglucose-positron emission tomography (FDG-PET) can facilitate a more accurate treatment response assessment and patient selection. Finally, the development of modern RT techniques, such as intensity-modulated and image-guided RT as well as FDG-PET-based RT planning, could further increase the therapeutic ratio of CRT. Conclusion Altogether, CRT constitutes an important tool in the treatment armamentarium for esophageal cancer. Further optimization of CRT using modern technology and imaging, targeted therapies

    Thirty patients with hyperthyroidism were were prepared for subtotal thyroidectomy with propranolol. Rapid control of thyrotoxic symptoms occurred in all, and there were no undesirable drug reactions. There were no instances of post-operative thyroid storm. The drug was as effective and safe in four patients who were pregnant as it was in the other 26 patients discussed. We consider propranolol to be the drug of choice in the preoperative preparation of most patients with thyrotoxicosis.

    AIM: To evaluate the prognostic value of preoperative carcinoembryonic antigen (CEA), carbohydrate antigen (CA)19-9, and CA50 in patients undergoing D2 resection. METHODS: We evaluated 363 patients with gastric cancer who underwent gastrectomy at our hospital from January 2006 to December 2009. Blood samples were obtained from each patient within 1 wk before surgery. The cut-off values for serum CEA, CA19-9, and CA50 were 5 ng/mL, 37 U/mL, and 20 U/mL, respectively. The correlation between preoperative tumor marker levels and prognosis was studied by means of univariate and multivariate analyses. RESULTS: The preoperative serum positive rates of CEA, CA19-9 and CA50 were 24.0%, 18.9% and 24.5%, respectively. The positivity rate of serum CEA was significantly correlated with age (P < 0.001), sex (P = 0.022), tumor size (P = 0.007) and depth of invasion (P = 0.018); CA19-9 with tumor size (P = 0.042) and lymph node metastasis (P < 0.001); and CA50 only with lymph node metastasis (P = 0.001). In multivariate analysis, tumor size, T category, N category, vascular or neural invasion, and adjuvant chemotherapy were independent prognostic factors for overall survival. CA19-9 had an independent prognostic significance in patients without adjuvant chemotherapy (P = 0.027). CONCLUSION: Preoperative serum CEA, CA19-9 and CA50 are prognostic in patients with gastric cancer. Only CA19-9 is an independent prognostic factor after surgery without adjuvant chemotherapy.

    Advancements in total ankle arthroplasty (TAA) over the past several decades have led to improved patient outcomes and implant survivorship. Despite these innovations, many implant manufacturers still consider a preoperative coronal plane deformity greater than 10° a relative contraindication to TAA. Without proper intraoperative alignment, these implants may experience abnormal wear and hardware failure. Correcting these deformities, often through the use of soft tissue procedures and/or osteotomies, not only increases the difficulty of a case, but also the intraoperative time and radiation exposure. The authors report a case in which a 54-year-old man with a severe right ankle varus deformity of 29° underwent successful TAA using the INBONE II Prophecy total ankle system (Wright Medical Technology, Inc, Memphis, Tennessee) and additional soft tissue reconstruction. Intraoperatively, the patient's coronal deformity was corrected to 1.8°. At 8 months postoperatively, the patient ambulated without restriction and had substantial improvement in validated patient outcome scores, specifically the Academy of Orthopaedic Surgeons Foot and Ankle Module and the Short Form Health Survey-12 This unique report documents the first time that this particular implant, with an exclusive preoperative computed tomography-derived patient-specific guide, has been used effectively for a severe preoperative varus deformity greater than 20° without the need for an osteotomy. Future studies should be directed toward the prospective evaluation of different total ankle implant systems and their outcomes with severe coronal plane deformity, specifically computed tomography-derived patient-specific guided implants.

    The development of a surgical technique that removes the tumour and all local draining nodes in an intact package, namely total mesorectal excision (TME) surgery, has provided the impetus for a more selective approach to the administration of preoperative therapy. One of the most important factors that governs the success of TME surgery is the relationship of tumour to the circumferential resection margin (CRM). Tumour involves the CRM in up to 20% of patients undergoing TME surgery, and results in both poor survival and local recurrence. It is therefore clear that the importance of the decision regarding the use of pre-operative therapy lies with the relationship of the tumour to the mesorectal fascia. In addition, a high-spatial-resolution MRI technique will identify tumours exhibiting other poor prognostic features, namely, extramural spread >5 mm, extramural venous invasion by tumour, nodal involvement, and peritoneal infiltration. The potential benefits of a selective approach using MRI-based selection criteria are evident. That is, over 50% of patients can be treated successfully with primary surgery alone without significant risk of local recurrence or systemic failure. Of the remainder, potentially dramatic improvements may be achieved through the use of intensive and targeted preoperative therapy aimed not only at reducing the size of the primary tumour and rendering potentially irresectable tumour resectable with tumour-free circumferential margins, but also at enabling patients at high risk of systemic failure to benefit from intensive combined modality therapy aimed at eliminating micrometastatic disease.

    The entire process of Clostridium difficile colonization to infection develops in large intestine. However, the real colonization pattern of C. difficile in preoperative colorectal cancer patients has not been studied. In this study, 33 C. difficile strains (16.1%) were isolated from stool samples of 205 preoperative colorectal cancer patients. C. difficile colonization rates in lymph node metastasis patients (22.3%) were significantly higher than lymph node negative patients (10.8%) (OR=2.314, 95%CI=1.023-5.235, P =0.025). Meanwhile, patients positive for stool occult blood had lower C. difficile colonization rates than negative patients (11.5% vs. 24.0%, OR=0.300, 95%CI=0.131-0.685, P =0.019). A total of 16 sequence types were revealed by multilocus sequence typing. Minimum spanning tree and time-space cluster analysis indicated that all C. difficile isolates were epidemiologically unrelated. Antibiotic susceptibility testing showed all isolates were susceptible to vancomycin and metronidazole. The results suggested that the prevalence of C. difficile colonization is high in preoperative colorectal cancer patients, and the colonization is not acquired in the hospital. Since lymph node metastasis colorectal cancer patients inevitably require adjuvant chemotherapy and C. difficile infection may halt the ongoing treatment, the call for sustained monitoring of C. difficile in those patients is apparently urgent.

    Preoperative preparation of paediatric patients and their environment in order to prevent anxiety is an important issue in paediatric anaesthesia. Anxiety in paediatric patients may lead to immediate negative postoperative responses. When a child undergoes surgery, information about the child's anaesthesia must be provided to parents who are responsible for making informed choices about healthcare on their child's behalf. A combination of written, pictorial, and verbal information would improve the process of informed consent. The issue of parental presence during induction of anaesthesia has been a controversial topic for many years. Potential benefits from parental presence at induction include reducing or avoiding the fear and anxiety that might occur in both the child and its parents, reducing the need for preoperative sedatives, and improving the child's compliance even if other studies showed no effects on the anxiety and satisfaction level. The presence of other figures such as clowns in the operating room, together with one of the child's parents, is an effective intervention for managing child and parent anxiety during the preoperative period.

    Lung resection is still the only potentially curative therapy for patients with localized non-small lung cancer (NSCLC). However, the presence of cardiovascular comorbidities and underlying lung disease increases the risk of postoperative complications. Various studies have evaluated the use of different preoperative tests in order to identify patients with an increased risk for postoperative complications, associated with prolonged hospital stay and increased morbidity and mortality. In this topic review, we discuss the role of cardiopulmonary exercise testing (CPET) as one of the preoperative tests suggested for lung cancer patients scheduled for lung resection. We describe different types of exercise testing techniques and present algorithms of preoperative evaluation in lung cancer patients. Overall, patients with maximal oxygen consumption (VO2max) <10 mL/kg/min or those with VO2max <15 mL/kg/min and both postoperative FEV1 and DLCO<40% predicted, are at high risk for perioperative death and postoperative cardiopulmonary complications, and thus should be offered an alternative medical treatment option.

    This study was designed to evaluate 4 preoperative skin preparations, that is, more specifically, to compare the efficacy of chlorhexidine gluconate (CG) and povidone-iodine (PI), as well as 2 hair removal techniques (clipper alone or clipper followed by razor) for preoperative skin preparation in cattle. The 4 protocols resulted in a significant decrease in the number of bacterial colony-forming units (cfu). Group 4 (clipping + shaving + CG) had a significantly lower number of preoperative cfu per gel plate compared with groups 1 (clipping + PI) and 3 (clipping + shaving + PI). Skin reaction frequency was significantly higher in groups 3 and 4 (47.8% for both protocols) than in groups 1 and 2 (clipping + PI or CG) (8.7% for both). Wound infection frequency was 4.3% (4/92) and no significant difference was observed between the 4 treatment groups. The 4 protocols tested were equivalent as to efficacy and satisfactorily decreased skin microflora. Clipping alone was shown to be preferable to clipping plus shaving as a method of hair removal in cattle, with fewer skin reactions and no more wound infections.

    Binaural beats are an auditory illusion perceived when two different pure-tone sine waves are presented one to each ear at a steady intensity and frequency. We evaluated their effectiveness in reducing preoperative anxiety in dentistry. Sixty patients (30 in each group) who were to have impacted third molars removed were studied (experimental group: 20 women and 10 men, mean (range) age 24 (18-35) years, and control group: 22 women and 8 men, mean (range) age 28 (15-47) years). All patients were fully informed about the operation preoperatively, and their anxiety recorded on a visual analogue scale (VAS). The local anaesthetic was given and the patients waited for 10minutes, during which those in the experimental group were asked to listen to binaural beats through stereo earphones (200Hz for the left ear and 209.3Hz for the right ear). No special treatment was given to the control group. In both groups anxiety was then recorded again, and the tooth removed in the usual way. The paired t test and t test were used to assess the significance of differences between groups. The degree of anxiety in the control group was unchanged after the second measurement (p=0.625), while that in the experimental group showed a significant reduction in anxiety (p=0.001). We conclude that binaural beats may be useful in reducing preoperative anxiety in dentistry. Copyright © 2017 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    In spite of the declining incidence of gastric cancer (GC) in recent years, the mortality rate is still high. The asymptomatic nature and nonspecific clinical manifestations combined with the lack of efficient screening programs delay the diagnosis of GC. Therefore, the prevalence of advanced gastric cancer (AGC) has prompted the need for aggressive and intensive treatment options. Among the various treatment options for AGC, surgery is still the mainstay. However, the efficacy of surgery alone is not established. Results from multiple randomized controlled trials suggest that preoperative chemotherapy is promising intervention for the treatment and management of AGC. The main objective of neoadjuvant chemotherapy is to downstage or control micrometastasis in resectable tumor before surgery. On the other hand, conversion chemotherapy refers to surgical treatment aiming at R0 resection after chemotherapy for originally nonresectable or marginally resectable tumors. Nevertheless, preoperative chemoradiotherapy is considered beneficial for AGC patients. Over the last few decades, the combination of chemotherapy and targeted therapy prior to surgery demonstrated great results for the treatment of AGC. The rapid developments in genomics and proteomics have heralded the era of precision medicine. The combination of preoperative chemotherapy and precision medicine may enhance survival in AGC patients. PMID:28105420

    The entire process of Clostridium difficile colonization to infection develops in large intestine. However, the real colonization pattern of C. difficile in preoperative colorectal cancer patients has not been studied. In this study, 33 C. difficile strains (16.1%) were isolated from stool samples of 205 preoperative colorectal cancer patients. C. difficile colonization rates in lymph node metastasis patients (22.3%) were significantly higher than lymph node negative patients (10.8%) (OR=2.314, 95%CI=1.023-5.235, P =0.025). Meanwhile, patients positive for stool occult blood had lower C. difficile colonization rates than negative patients (11.5% vs. 24.0%, OR=0.300, 95%CI=0.131-0.685, P =0.019). A total of 16 sequence types were revealed by multilocus sequence typing. Minimum spanning tree and time-space cluster analysis indicated that all C. difficile isolates were epidemiologically unrelated. Antibiotic susceptibility testing showed all isolates were susceptible to vancomycin and metronidazole. The results suggested that the prevalence of C. difficile colonization is high in preoperative colorectal cancer patients, and the colonization is not acquired in the hospital. Since lymph node metastasis colorectal cancer patients inevitably require adjuvant chemotherapy and C. difficile infection may halt the ongoing treatment, the call for sustained monitoring of C. difficile in those patients is apparently urgent.

    A preoperative quantitative evaluation of soft tissues is helpful for planning total knee arthroplasty, in addition to the conventional clinical examinations involved in moving the knee manually. We evaluated preoperative coronal laxity with osteoarthritis in patients undergoing total knee arthroplasty by applying a force of 150 N with an arthrometer. We examined a consecutive series of 120 knees in 102 patients. The median laxity was 0° in abduction and 8° in adduction. The femorotibial angle on non-weight-bearing standard anteroposterior radiographs was 180° and correlated with both abduction (r = −0.244, p = 0.007) and adduction (r = 0.205, p = 0.025) laxity. The results of a regression analysis suggested that the femorotibial angle is helpful for estimating both laxities. Considering the many reports on how to obtain well-balanced soft tissues, stress radiographs might help to improve the preoperative planning for gaining the optimal laxity deemed appropriate by surgeons.

    Hospitalized patients and patients scheduled to undergo surgery or invasive medical procedures experience high levels of anxiety. Recently, music intervention has been evaluated for its anxiolytic effects in preoperative patients. The aim of this integrative review was to illustrate the varying methodological approaches utilized to assess the efficacy of a music intervention in reducing preoperative anxiety in adults. A total of 11 articles, meeting the inclusion criteria, were evaluated and included. Three of the eight (38%) studies, investigating the effect of listening to music on blood pressure, concluded that listening to music lowered blood pressure. Three of seven (43%) studies, investigating the relationship between listening to music and heart rate, illustrated patterns of decreased heart rates. Finally, two of four (50%) studies, investigating relaxing effects of listening to music on breathing, provided evidence of a decreased respiratory rate. There was inconsistent evidence regarding music's effectiveness in lowering blood pressure, heart rate and respirations in anxious patients. However, music intervention can still be used by nurses to create a calm, relaxing atmosphere geared towards reducing anxiety in preoperative patients. © 2011 The Authors.

    Adenosquamous carcinoma of the pancreas is a rare tumor which has a less favorable prognosis than common ductal cell carcinoma of the pancreas, and a definite preoperative diagnosis of this tumor is quite difficult. We herein report two cases of this rare variant. The patients were a 41-year-old man (patient 1) and a 67-year-old woman (patient 2). Patient 1 had a hypoechoic mass measuring 3 cm in the uncus of the pancreas, while patient 2 had a huge mass, measuring 8 cm, in the tail of the pancreas. Patient 2 was successfully diagnosed preoperatively as having an adenosquamous carcinoma, by cytological examination of the pure pancreatic juice obtained by endoscopic retrograde pancreatic juice aspiration. A pylorus-preserving pancreatoduodenectomy was performed for patient 1, and a distal pancreatectomy with resection of the spleen and the left kidney was performed for patient 2. Subsequent pathological findings of these two tumors revealed adenosquamous carcinoma of the pancreas. K- ras point mutation, p53 overexpression, and telomerase activity in both tumor specimens were detected by the mutant allele specific amplification method, immunohistochemical staining, and telomeric repeat amplification protocol assay, respectively. The two patients died of recurrent disease 5 and 4 months, respectively, after surgery. Cytological examination of pure pancreatic juice is a useful modality for the preoperative diagnosis of this tumor, and frequent molecular alterations may be associated with the poor prognosis of adenosquamous carcinoma of the pancreas.

    2011-01-01

    Aim: Preoperative fluid and electrolyte management is usually performed by intravenous therapy. We investigated the safety and effectiveness of oral rehydration therapy (ORT) for preoperative fluid and electrolyte management of surgical patients. Methods: The study consisted of two studies, designed as a prospective observational study. In a pilot study, 20 surgical patients consumed 1000 mL of an oral rehydration solution (ORS) until 2 h before induction of general anesthesia. Parameters such as serum electrolyte concentrations, fractional excretion of sodium (FENa) as an index of renal blood flow, volume of esophageal-pharyngeal fluid and gastric fluid (EPGF), and patient satisfaction with ORT were assessed. In a follow-up study to assess the safety of ORT, 1078 surgical patients, who consumed ORS until 2 h before induction of general anesthesia, were assessed. Results: In the pilot study, water, electrolytes, and carbohydrate were effectively and safely supplied by ORT. The FENa value was increased at 2 h following ORT. The volume of EPGF collected following the induction of anesthesia was 5.3±5.6 mL. In the follow-up study, a small amount of vomiting occurred in one patient, and no aspiration occurred in the patients. Conclusion: These results suggest that ORT is a safe and effective therapy for the preoperative fluid and electrolyte management of selected surgical patients. PMID:21897763

    There is no objective and readily accessible method for the preoperative determination of atypical characteristics of a meningioma grade. To evaluate the feasibility of using fractal analysis as an adjunctive tool to conventional radiological techniques in visualizing histopathological features of meningiomas. A group of 27 patients diagnosed with atypical (WHO grade II) meningioma and a second group of 27 patients with benign (WHO grade I) meningioma were enrolled in the study. Preoperative brain magnetic resonance (MR) studies (T1-wieghted, post-gadolinium) were processed and analyzed to determine the average fractal dimension (FDa) and maximum fractal dimension (FDm) of the contrast-enhancing region of the tumor using box-count method. FDa and FDm as well as particular radiological features were included in the logistic regression model as possible predictors of malignancy. The cohort consisted of 34 women and 20 men, mean age of 62 ± 15 yr. Fractal analysis showed good interobserver reproducibility (Kappa >0.70). Both FDa and FDm were significantly higher in the atypical compared to the benign meningioma group (P < .0001). Multivariate logistic regression model reached statistical significance with P = .0001 and AUC = 0.87. The FDm, which was greater than 1.31 (odds ratio [OR], 12.30; P = .039), and nonskull base localization (OR, .052; P = .015) were confirmed to be statistically significant predictors of the atypical phenotype. Fractal analysis of preoperative MR images appears to be a feasible adjunctive diagnostic tool in identifying meningiomas with potentially aggressive clinical behavior.

    This study aimed to verify whether psychologists and game activities could reduce preoperative anxiety and promote compliance in paediatric patients. More specifically, we sought to evaluate whether it would be better to propose contextualized games or just distracting activities. A total of 104 children undergoing surgery were assigned to the following 4 conditions of treatment: (1) contextual games and psychological accompaniment, (2) only contextual games, (3) distracting activities, and (4) only psychological accompaniment. Observed children's anxiety was assessed using modified Yale Preoperative Anxiety Scale and compliant behaviours with modified form of Induction Compliance Checklist. Children in the first condition (complete intervention - contextual games and psychological accompaniment) were less anxious and more cooperative in the preoperative period and during the induction of anaesthesia than in the other three conditions. In particular, contextual activities (second condition) were found to be more efficient than psychological accompaniment (fourth condition), whereas the worst condition was proposing only distracting activities (third condition). In order to help young hospitalized patients in paediatric surgery structures, it is necessary to propose games that can prepare them for what will happen as well as the support of a psychologist.

    Pelvic discontinuity (PD) is a rare but devastating mechanism of failure in total hip arthroplasty. Radiographic findings have been described for the identification of PD. However, no study has specifically examined radiographic parameters and the utility of specific views in the preoperative identification of PD. We performed a retrospective review of 133 patients who underwent acetabular revision for PD. Preoperative radiographic studies were reviewed including anteroposterior pelvis (AP; n = 133), true lateral hip (n = 132), Judet (n = 47), false profile (n = 4), and computed tomography scans (n = 14). Radiographs were read by the senior authors to identify the following parameters suggestive of PD: visible fracture line, medial migration of the inferior hemipelvis, and obturator ring asymmetry. Using only the AP view, the fracture line was visible in 116 (87%), medial migration of the inferior hemipelvis in 126 (95%), and obturator ring asymmetry in 114 (86%). A fracture line was visualized in 65 of 132 hips (49%) evaluated with laterals, 36 of 47 hips (77%) evaluated with Judet views, 3 of 4 (75%) evaluated with a false profile view, and 10 of 14 (71%) evaluated with computed tomography. Preoperative evaluation with a combination of an AP pelvis radiograph, plus a true lateral radiograph of the hip, plus Judet films in combination with the criteria for discontinuity defined in this article, allowed for identification of PD in a 100% of patients.

    Despite recent advances in chemotherapeutic agents, the prognosis for metastatic colon cancer remains poor. Over the past two decades, hepatic metastasectomy has emerged as a promising technique for improving survival in patients with metastatic colon cancer and in some cases providing long-term cure. To maximize safety and efficacy of metastasectomy, appropriate pre-operative imaging is needed. Advancements in computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) have led to improved detection of occult lesions and better definition of surgical anatomy. While CT, PET and MRI have a comparable sensitivity for detection of large liver metastases, MRI excels at detection of subcentimeter liver metastases compared to CT and FDG-PET, especially with the combination of diffusion weighted imaging (DWI) and hepatocyte-specific contrast agents. CT may be useful as a screening modality or in preoperative planning such as volumetric estimation of the remnant liver size or in defining preoperative arterial anatomy for hepatic artery infusion pump placement. While technologic advancements have led to unprecedented image quality and clarity, this does not replace the need for a dedicated, competent radiologist with experience in hepatic imaging.

    Objectives Current literature is in disagreement regarding female sex as a risk factor for pain after surgery. We hypothesized, that sex differences exist but that they are influenced by certain factors. Here, we investigated the influence of sex for different clinically relevant postoperative pain (POP) outcome parameters and evaluated the role of assumed confounders for sex differences. Methods From 1372 screened patients undergoing orthopedic surgery at the university hospital of Muenster between March 2010 and June 2011, 890 patients were included. The validated International Pain Outcomes questionnaire was used to assess the role of sex for several aspects of POP including pain severity, physical and emotional functional interference as well as the patient’s perceptions of the care they received on the first day after surgery. Assessed confounders were age, preoperative chronic pain, anesthetic technique employed and surgical procedure. All statistical analyses were performed with SPSS Statistics Software 22. Results Linear regression analysis demonstrated that sex was a statistically significant risk factor for “worst pain since surgery”. Additionally, significant sex differences in “time spent in severe pain”, “feeling anxious due to pain”, “feeling helpless due to pain” and “opioid consumption since surgery” could be identified. An univariate general linear model showed that “age” and “preoperative pain” were significant confounders for sex differences. Further descriptive subgroup analysis revealed consistent sex differences for several POP outcome variables especially in patients older than 50 years or patients with preoperative chronic pain. However, sex differences disappeared in younger patients and in patients without preoperative pain. Discussion Our data confirmed that sex differences exist in pain intensity and frequency, pain interference with feelings and opioid consumption during the first 24 hours postoperatively

    Purpose: Preoperative chemotherapy and radiation has become the standard of care for many patients with rectal cancer. The therapy may have toxicity and delays definitive surgery. It would therefore be desirable to identify those cancers that will not regress with preoperative therapy. We assessed a series of rectal cancers for the molecular changes of loss of heterozygosity of the APC and DCC genes, K-ras mutations, and microsatellite instability, changes that have clearly been associated with rectal carcinogenesis. Methods and Materials: Diagnostic colonoscopic biopsies from 53 patients who received preoperative chemotherapy and radiation were assayed using polymerase chain reaction techniques followed by single-stranded conformation polymorphism and DNA sequencing. Regression of the primary tumor was evaluated using the surgically removed specimen. Results: Twenty-three lesions (45%) were found to have a high degree of regression. None of the molecular changes were useful as indicators of regression. Conclusions: Recognized molecular changes critical for rectal carcinogenesis including APC and DCC loss of heterozygosity, K-ras mutations, and microsatellite instability are not useful as indicators of tumor regression following chemoradiation for rectal carcinoma.

    The use of body mass index (BMI) as the only criterion to indicate bariatric surgery is currently under discussion. There is growing evidence that supports bariatric surgery in carefully selected patients with lower BMI. To report our experience in bariatric surgery in>1000 patients with BMI<35 kg/m(2) and their results at 1 year. University hospital (censored). A retrospective analysis was performed in patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (SG) with preoperative BMI<35 kg/m(2) from January 2008 to December 2011. Demographic and anthropometric data, preoperative co-morbidities, and perioperative variables were retrieved. Weight loss and co-morbidities progression were analyzed 1 year after surgery and compared among procedures. A P value<.05 was considered significant. We identified 1119 patients: mean age 38.8±11.4, 951 (85%) women, preoperative weight 87.5±9.3 kg and BMI 33.1 (31.9-34.1) kg/m(2). Preoperatively, 11.7% had type 2 diabetes mellitus, 25.9% arterial hypertension, 55.6% insulin resistance, and 53.2% dyslipidemia. In total, 283 patients (25.2%) underwent LRYGB and 836 (74.8%) SG. One year after surgery (follow-up: 66.67%) patients reached 24.5 (22.8-26.4) BMI and the percentage of excess of weight loss (%EWL) was 107.9±36.6%. Diabetes, hypertension, insulin resistance, and dyslipidemia remission/improvement rates were 54/39%, 58/29%, 72/17%, and 54/30%, respectively. Bariatric surgery in selected class I obesity patients can safely be performed. We have observed good results in terms of weight loss and co-morbidity improvement/remission.

    After cardiac surgery, physical therapy is a routine procedure delivered with the aim of preventing postoperative pulmonary complications. To determine if preoperative physical therapy with an exercise component can prevent postoperative pulmonary complications in cardiac surgery patients, and to evaluate which type of patient benefits and which type of physical therapy is most effective. Searches were run on the Cochrane Central Register of Controlled Trials (CENTRAL) on the Cochrane Library (2011, Issue 12 ); MEDLINE (1966 to 12 December 2011); EMBASE (1980 to week 49, 2011); the Physical Therapy Evidence Database (PEDro) (to 12 December 2011) and CINAHL (1982 to 12 December 2011). Randomised controlled trials or quasi-randomised trials comparing preoperative physical therapy with no preoperative physical therapy or sham therapy in adult patients undergoing elective cardiac surgery. Data were collected on the type of study, participants, treatments used, primary outcomes (postoperative pulmonary complications grade 2 to 4: atelectasis, pneumonia, pneumothorax, mechanical ventilation > 48 hours, all-cause death, adverse events) and secondary outcomes (length of hospital stay, physical function measures, health-related quality of life, respiratory death, costs). Data were extracted by one review author and checked by a second review author. Review Manager 5.1 software was used for the analysis. Eight randomised controlled trials with 856 patients were included. Three studies used a mixed intervention (including either aerobic exercises or breathing exercises); five studies used inspiratory muscle training. Only one study used sham training in the controls. Patients that received preoperative physical therapy had a reduced risk of postoperative atelectasis (four studies including 379 participants, relative risk (RR) 0.52; 95% CI 0.32 to 0.87; P = 0.01) and pneumonia (five studies including 448 participants, RR 0.45; 95% CI 0.24 to 0.83; P = 0.01) but not of

    Choledocholithiasis is the most common cause of obstructive jaundice and occurs in 5-10% of patients with cholelithiasis. To design a preoperative predictive score for choledocholithiasis. A prospective study was carried out in 556 patients admitted to our department for biliary disease. Preoperative clinical, laboratory, and ultrasound variables were compared between patients without choledocholithiasis and 65 patients with this diagnosis. A multivariate logistic analysis was performed to obtain a predictive model of choledocholithiasis, determining sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Predictors of choledocholithiasis were the presence of a prior history of biliary disease (history of biliary colic, acute cholecystitis, choledocholithiasis or acute biliary pancreatitis) (p=0.021, OR=2.225, 95% CI: 1.130-4.381), total bilirubin values >4mg/dl (p=0.046, OR=2.403, 95% CI: 1.106-5.685), alkaline phosphatase values >150mg/dl (p=0.022 income, OR=2.631, 95%: 1.386-6.231), gamma-glutamyltransferase (GGT) values >100mg/dl (p=0.035, OR=2.10, 95% CI: 1.345-5.850), and an ultrasound finding of biliary duct >8mm (p=0.034, OR=3.063 95% CI: 1086-8649). A score superior to 5 had a specificity and PPV of 100% for detecting choledocholithiasis and a score less than 3 had a sensitivity and NPV of 100% for excluding this diagnosis. The preoperative score can exclude or confirm the presence of choledocholithiasis and allows patients to directly benefit from laparoscopic cholecystectomy (LC) or prior endoscopic retrograde cholangiopancreatography (ERCP).

    Hospitals use time-motion studies to monitor process effectiveness and patient waiting. Manual tracking is labor-intensive and potentially influences system performance. New technology known as indoor positioning systems (IPS) may allow automatic monitoring of patient waiting and progress. The authors tested whether an IPS can track patients through a multistep preoperative process. The authors used an IPS between October 14, 2005, and June 13, 2006, to track patients in a multistep ambulatory preoperative process: needle localization and excisional biopsy of a breast lesion. The process was distributed across the ambulatory surgery and radiology departments of a large academic hospital. Direct observation of the process was used to develop a workflow template. The authors then developed software to convert the IPS data into usable time-motion data suitable for monitoring process efficiency over time. The authors assigned tags to 306 patients during the study period. Eighty patients never underwent the procedure or never had their tag affixed. One hundred seventy-seven (78%) of the remaining 226 patients successfully matched the workflow template. Process time stamps were automatically extracted from the successful matches, measuring time before radiology (mean +/- SD, 77 +/- 35 min), time in radiology (105 +/- 35 min), and time between radiology and operating room (80 +/- 60 min), which summed to total preoperative time (261 +/- 67 min). The authors have demonstrated that it is possible to use a combination of IPS technology and sequence alignment pattern matching software to automate the time-motion study of patients in a multidepartment, multistep process with the only day-of-surgery intervention being the application of a tag when the patient arrives.

However, it rarely reported that how to determine the feasibility of the unilateral or bilateral approach and how to decide the puncture angle, the skin insertion site before the procedure. The aim of this study was to discuss the feasibility of PVP using unilateral pedicular approach by the three-dimensional positioning of computed tomography (CT) image. Materials and Methods: Under fluoroscopic guidance, 108 patients with 115 diseased vertebral bodies underwent PVP. The study was divided in two groups. Group A, fifty patients with 52 vertebrae received PVP without using preoperative CT measurements and puncture simulation. Group B, 58 patients with 63 vertebrae received PVP using preoperative CT measurements and puncture simulation. The skin needle entry point and puncture angle of the transverse plane and sagittal plane were determined by the software of PACS on preoperative CT image. The choice of unilateral or bilateral pedicular approach was decided based on the CT image before the procedure. PVP was carried out according to the measurement result above. The average time for a single vertebra operation, the success rate of single puncture and complications was evaluated and compared between Group A and Group B. Results: In Group A, technical success of unilateral PVP was 63.5% (33/52 vertebrae), and 92% (58/63 vertebrae) in Group B. The average time of operation in Groups A and B were (37.5 ± 5.5) and (28.5 ± 5.5) min, respectively. There was a significant difference in the time of single-vertebra operation and the success rates of unilateral PVP between Groups A and B. No serious complications developed during the followup period. Conclusions: The CT three-dimensional positioning measurement for PVP can increase the success rate of unilateral PVP. PMID:27904217

    Preoperative blood ordering is frequently in elective colon surgery, even for procedures that rarely require blood transfusion. Most often this procedure is performed without proper analysis of the real needs. The aim of this study was to evaluate the patients who receive transfusion and determining their associated factors. Retrospective study of all consecutive patients scheduled for elective colon surgery was carried out at 2007-2012. Several clinico-pathological and surgical variables were analyzed and predictive blood transfusion indices such as the cross-matched/transfusion ratio (C/T ratio), transfusion index and transfusion probability were calculated. Patients were divided in 2 groups according have received perioperative surgical transfusion or not. There were 457 surgery patients. A total of 171 blood units, in a 74 patients were perioperative transfused. Overall cross-matched transfused ratio was 5.34, the transfusion probability 162%, and the transfusion index 0.18. Variables that were significantly associated with receiving blood transfusion in a multivariable analysis were a preoperative haemoglobin level less than 10 g/dl (OR: 309.8; 95% CI: 52.7-985.2), chronic pulmonary obstructive disease (OR: 3.7; 95% CI: 1.3-10.7), oral anticoagulant therapy (OR: 5.7; 95% CI: 1.7-19.4) and surgical time over 120 min (OR: 10.7; 95% CI: 4.7-24.1). Likelihood of receiving perioperative transfusion in elective colon surgery is very low. Among their associated factors, the haemoglobin level less than 10 g/dl is the one with strongest association. Those patients with such low preoperative haemoglobin level should not be scheduled for elective colon surgery until they received specific treatment. Copyright © 2013 AEC.

    This paper presents the most common disorders of pituitary function: acromegaly, hypopituitarism, diabetes insipidus and syndrome similar to diabetes insipidus, in terms of their importance in preoperative preparation of patients. Pituitary function manages almost the entire endocrine system using the negative feedback mechanism that is impaired by these diseases. The cause of acromegaly is a pituitary adenoma, which produces growth hormone in adults. Primary therapy of acromegaly is surgical, with or without associated radiotherapy. If a patient with acromegaly as comorbidity prepares for non-elective neurosurgical operation, then it requires consultation with brain surgeons for possible delays of that operation and primary surgical treatment of pituitary gland. If operative treatment of pituitary gland is carried out, the preoperative preparation (for other surgical interventions) should consider the need for perioperative glucocorticoid supplementation. Panhypopituitarism consequences are different in children and adults and the first step in diagnosis is to assess the function of target organs. Change of electrolytes and water occurs in the case of pituitary lesions in the form of central or nephrogenic diabetes insipidus as a syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Preoperative preparation of patients with pituitary dysfunction should be multidisciplinary, whether it is a neurosurgical or some other surgical intervention. The aim is to evaluate the result of insufficient production of pituitary hormones (hypopituitarism), excessive production of adenohypophysis hormones (acromegaly, Cushing's disease and hyperprolactinemia) and the influence of pituitary tumours in surrounding structures (compression syndrome) and to determine the level of perioperative risk. Pharmacological suppressive therapy of the hyperfunctional pituitary disorders can have significant interactions with drugs used in the perioperative period.

    The implementation of preoperative chemoradiation combined with total mesorectal excision has reduced local recurrence rates in rectal cancer. However, the use of both types of treatment in upper rectal cancer is controversial. The purpose of this work was to assess oncological results after radical resection of upper rectal cancers compared with sigmoid, middle, and lower rectal cancers and to determine risk factors for local recurrence in upper rectal cancer. This was a retrospective analysis of prospectively collected data. This study was conducted in a tertiary care referral hospital in Valencia, Spain. Analysis included 1145 patients who underwent colorectal resection with primary curative intent for primary sigmoid (n = 450), rectosigmoid (n = 70), upper rectal (n = 178), middle rectal (n = 186), or lower rectal (n = 261) cancer. Oncological results, including local recurrence, disease-free survival, and cancer-specific survival, were compared between the different tumor locations. Univariate and multivariate analyses were performed to identify risk factors for local recurrence in upper rectal cancer. A total of 147 patients (82.6%) with upper rectal tumors underwent partial mesorectal excision, and only 10 patients (5.6%) of that group received preoperative chemoradiation. The 5-year actuarial local recurrence, disease-free survival, and cancer-specific survival rates for upper rectal tumors were 4.9%, 82.0%, and 91.6%. Local recurrence rates showed no differences when compared among all of the locations (p = 0.20), whereas disease-free survival and cancer-specific survival were shorter for lower rectal tumors (p = 0.006; p = 0.003). The only independent risk factor for local recurrence in upper rectal cancer was an involved circumferential resection margin at pathologic analysis (HR, 14.23 (95% CI, 2.75-73.71); p = 0.002). This was a single-institution, retrospective study. Most upper rectal tumors can be treated with partial mesorectal excision without the

    Carcinoembryonic antigen (CEA) remains the only recommended biomarker for follow-up care of colorectal cancer (CRC), but besides CEA, several other serological parameters have been proposed as prognostic markers for CRC. The present retrospective analysis investigates a comprehensive set of serum markers with regard to cancer-specific survival (CSS) and disease-free survival (DFS). A total of 472 patients with colon cancer underwent surgery for curative intent between January 1988 and June 2007. Preoperative serum was analyzed for the following parameters: albumin, alkaline phosphatase (aP), beta-human chorionic gonadotropin (βhCG), bilirubin, cancer antigen 125 (CA 125), cancer antigen 19-9 (CA 19-9), CA 72-4, CEA, C-reactive protein (CRP), cytokeratin-19 soluble fragment (CYFRA 21-1), ferritin, gamma-glutamyltransferase (γGT), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), hemoglobin, haptoglobin, interleukin-6, interleukin-8, creatinine, lactate dehydrogenase (LDH), serum amyloid A (SAA), and 25-hydroxyvitamin D. After a median follow-up period of 5.9 years, the overall 3- and 5-year CSS was 91.7 and 84.9 % and DFS rates were 82.7 % (3 years) and 77.6 % (5 years). Multivariate analyses confirmed preoperative CEA as an independent prognostic factor with regard to CSS and DFS. CA 19-9 and γGT also provided prognostic value for CSS and DFS, respectively. Younger age was negatively associated with DFS. According to UICC stage, CEA provided significant prognostic value with regard to CSS and DFS, while CA 19-9 was only prognostic for CSS. Combined analysis is able to identify patients with favorable prognosis. In addition to tumor baseline parameters, preoperative CEA could be confirmed as prognostic marker in colon cancer. CA 19-9 and γGT also provide additional prognostic value with regard to survival and recurrence in stage III and stage I disease, respectively. The combined use of CEA together with CA 19-9 and γGT improve

    Coagulation screening continues as a standard of care in many hip fracture pathways despite the 2011 guidelines from the Association of Anaesthetists of Great Britain and Ireland (AAGBI) which recommend that such screening be performed only if clinically indicated. This study aims to evaluate the use of pre-operative coagulation screening and explore its financial impact. Prospective data was collected in accordance with the "Standardised Audit of Hip Fractures in Europe" (SAHFE) protocol. All patients admitted to our hospital with hip fractures during a 12-month period from November 2011 to November 2012 were analysed. Data including coagulation results and the use of vitamin K or blood products were collected retrospectively from the hospital computer system. Patient subgroup analysis was performed for intraoperative blood loss, post-operative blood units transfused, haematoma formation and gastrointestinal haemorrhage. 814 hip fractures were analysed. 91.4% (n=744) had coagulation tests performed and 22.0% (n=164) had an abnormal result. Of these, 55 patients were taking warfarin leaving 109 patients who had abnormal results and were not taking warfarin. When this group (n=109) was compared to those who had normal test results (n=580) and to all other patients (n=705) there was no difference in intraoperative blood loss (p=0.79, 0.78), postoperative transfusion (p=0.38, 0.30), postoperative haematoma formation (p=0.79, 1.00), or gastrointestinal haemorrhage (p=0.45, 1.00), respectively. In those who were not taking warfarin, but had abnormal results, none had treatment to reverse their coagulopathy with either vitamin K or blood products. By omitting pre-operative coagulation tests in patients who are not taking warfarin, we estimate a financial saving of between £66,500 and £432,250 per annum. This study supports the hypothesis that routine pre-operative coagulation screening is unnecessary in hip fracture patients unless they take warfarin or have a known

    Introduction Surgical complications may be avoided by preoperative templating in trauma hemiarthroplasty. Materials and methods Digital templates for the Stryker™ range of Thompson's prostheses were created and fifty trauma patients that had undergone cemented hemiarthroplasty were retrospectively templated by 2 blinded surgeons. Results Templating for prosthesis size was highly accurate with excellent Inter and intra-observer reproducibility. Sensitivity for identifying femoral canals too narrow for a Thompsons was 100%. Conclusions Templating is a valuable tool and should be standard practice in trauma. We have demonstrated that it is possible to generate custom templates to allow accurate templating. PMID:26566327

    Anesthetic assessment traditionally included a series of laboratory tests intended to detect undiagnosed diseases, and to ensure that the patient undergoes surgery following safety criteria. These tests, without a specific clinical indication, are expensive, of questionable diagnostic value and often useless. In the context of outpatient surgery, recent evidence suggests that patients of any age without significant comorbidity, ASA physical status gradei and grade ii, do not need additional preoperative tests routinely. The aim of the present recommendations is to determine the general indications in which these tests should be performed in ASA gradei and grade ii patients undergoing ambulatory surgery.

    An accurate preoperative staging of nodal status is crucial in gastric cancer, because it has a great impact on prognosis and therapeutic decision-making. Different staging methods have been evaluated for gastric cancer in order to predict nodal involvement. So far, no technique could meet the necessary requirements, which include a high detection rate of infiltrated lymph nodes and a low frequency of false-positive results. This article summarizes different staging methods used to assess lymph node status in patients with gastric cancer, evaluates the evidence, and proposes to establish new methods. PMID:28217758

    Two cases of endometriosis infiltrating the round ligament and associated with an inguinal hernia are presented. The initial diagnosis was irreducible hernia, since this rare association often causes unusual preoperative symptoms and diagnostic problems. Diagnosis is frequently made by histologic examination. Surgery is the treatment of choice both for hernia and for endometriosis, and is locally curative. However, in a fertile woman with a painful mass in the inguinal region the possibility of endometriosis should be considered, and if suspected at inguinal exploration a laparoscopy should be made to rule out the presence of intraperitoneal endometriosis.

    The surgical removal of brain tumours in so-called eloquent regions is frequently associated with a high risk of causing disabling postoperative deficits. Among the preoperative techniques proposed to help neurosurgical planning and procedure, navigated transcranial magnetic stimulation (nTMS) is increasingly performed. A high level of evidence is now available in the literature regarding the anatomical and functional accuracy of this mapping technique. This article presents the principles and facts demonstrating the value of using nTMS in clinical practice to preserve motor or language functions from deleterious lesions secondary to brain tumour resection or epilepsy surgery.

    Sinonasal glomangiopericytoma is a benign rare tumour of pericytes that accounts for less than 0.5% of all sinonasal tumours. It is an indolent tumour with a macroscopic appearance of common inflammatory polyps. We report the case of a 55-year-old male who presented with right nasal obstruction. CT and MRI examinations demonstrated a soft-tissue mass that obstructed mainly the right nasal cavity. Biopsy revealed glomangiopericytoma. The tumour was treated with preoperative embolisation followed by complete endoscopic resection. Very few cases have been reported to be treated in this way. PMID:27994648

    Severe post-caesarean pain remains an important issue associated with persistent pain and postpartum depression. Women's sleep quality prior to caesarean delivery and its influence on postoperative pain and analgesic intake have not been evaluated yet. Women undergoing caesarean delivery with spinal anaesthesia (bupivacaine 12 mg, fentanyl 20 μg, morphine 100 μg) were evaluated preoperatively for sleep quality using the Pittsburgh Sleep Quality Index (PSQI) questionnaire (PSQI 0-5 indicating good sleep quality, PSQI 6-21 poor sleep quality). Peak and average postoperative pain scores at rest, movement and uterine cramping were evaluated during 24 h using a verbal numerical pain score (VNPS; 0 indicating no pain and 100 indicating worst pain imaginable), and analgesic intake was recorded. Primary outcome was peak pain upon movement during the first 24 h. Seventy-eight of 245 women reported good sleep quality (31.2%; average PSQI 3.5 ± 1.2) and 167 poor sleep quality (68.2%; average PSQI 16.0 ± 3.4; p < 0.001). Women with poor sleep quality had significantly higher peak pain scores upon movement (46.7 ± 28.8 vs. 36.2 ± 25.6, respectively; p = 0.006). With multivariable logistic regression analysis, poor sleep quality significantly increased the risk for severe peak pain upon movement (VNPS ≥70; OR 2.64; 95% CI 1.2-6.0; p = 0.02). A significant proportion of women scheduled for caesarean delivery were identified preoperatively as having poor sleep quality, which was associated with more severe pain and increased analgesic intake after delivery. The PSQI score may therefore be a useful tool to predict increased risk for acute post-caesarean pain and higher analgesic requirements, and help tailor anaesthetic management. Multiple studies have evaluated predictors for severe acute pain after caesarean delivery that may be performed in a clinical setting, however, sleep quality prior to delivery has not been included in predictive models for post

    Preoperative fasting aims to increase patient safety by reducing the risk of adverse events during general anaesthesia. However, prolonged fasting may be associated with dehydration, hypoglycaemia and electrolyte imbalance as well as patient discomfort. We aimed to examine compliance with the current best practice guidelines in a large surgical unit and to identify areas for improvement. Adult patients undergoing elective and emergency general, orthopaedic, gynaecology and vascular surgery procedures in the Royal Infirmary of Edinburgh were surveyed over a 3-month period commencing November 2011. A standardised questionnaire was used to collect information on the duration of preoperative fasting and the advice administered by medical and nursing staff. 292 patients were included. Median fast from solids was 13.5 h for elective patients (IQR 11.5-16) and 17.38 h for emergency patients (IQR 13.68-28.5 h). Similarly, the median fast from fluids was 9.36 h for elective patients (IQR 5.38-12.75 h) and 12.97 h for emergency patients (IQR 8.5-16.22 h). The instructions that elective patients received contributed to prolonged fasting times. The median fast for elective patients fully compliant with fasting advice would be 10 h for solids (IQR 8.75-12 h) and 6.25 h (IQR 3.83-9.25 h) for clear fluids. Elective patients fasted for longer than recommended confirming that clinical practice is slow to change. The use of universal fasting instructions and patient choice are factors that unnecessarily prolong preoperative fasting, which however appears to be multifactorial. Service improvement by abbreviation of the observed fasting periods will rely on targeted staff education and effective clinical communication by provision of written information for both elective and emergency surgical patients. The routine use of preoperative nutritional supplements may need to be re-examined when further evidence is available.

Prospective study. General hospital, Denmark. 180 consecutive non-jaundiced patients referred with symptomatic gallstones for elective cholecystectomy. LFT, abdominal ultrasonography, MRCP, endoscopic retrograde cholangiopancreatography (ERCP), questionnaire. Positive and negative predictive values and accuracy of MRCP, number of patients with asymptomatic stones, and correlation of symptoms with the presence of stones. 26/180 patients had common duct stones (14%). Only one (<1%) had an asymptomatic stone. For detection of such stones, MRCP's positive predictive value was 0.95 (95% confidence interval (CI): 0.86 to 1.00), negative predictive value 0.96 (0.93 to 0.99), and accuracy 0.85 (0.93 to 0.99). MRCP missed 5 stones 1-4 mm in size in 5 patients; 17/64 patients with raised LFTs had stones (27%). The probability of stones was highest when the patients had both raised LFTs and a dilated common (>7 mm) bile duct (82%). There were no readmissions with ductal stones in the 6-month postoperative period. The predicive values of MRCP were fairly good, but MRCP misses some small stones <5 mm in size. Asymptomatic stones in the common duct are not common in this population and should not be screened for. The probability of stones increases with the number of predictive factors. Patients should be questioned carefully about signs of biliary obstruction, and only be offered preoperative MRCP should they have a suspicious history, raised LFTs, or a dilated common duct.

    Preoperative evaluation of patients with paralytic scoliosis should take into account the consequences of surgery on the every day life of the patient. However, the parameters that are customarily used in these operations relate only to very narrow measures such as the angle of scoliosis or kyphosis. The aim of this study was to introduce a set of instruments appropriate for measuring both function and activities in paralytic scoliosis patients. The study took as its starting point the WHO International Classification of Impairments, Disabilities and Handicaps (ICIDH), in which an activity is described at the level of the individual and function at the level of the organ. A consecutive series of 100 paralytic scoliosis patients with 18 different diagnoses were evaluated preoperatively with a set of instruments that had been specially developed at Linköping hospital, in which the variables are classified according to the system used in the ICIDH. The set of instruments included general information and evaluation of activities and function--sitting, balance, weight distribution to sitting surface, angle of scoliosis, reaching, pain estimation, activities of daily living (ADL) Barthel and ADL Klein and Bell, care given, time spent resting, and seating supports). The results showed that patients with paralytic scoliosis constitute a heterogeneous group in activities and function. Even when the patients were grouped into four subgroups according to the Scoliosis Research Society Classification, they remained very heterogeneous. However, reaching, Klein and Bell Activities of Daily Living and pain could only evaluate patients who could understand verbal instructions. In those who could not, assessment relied more heavily on measures of function and level of dependence. It was concluded that the choice of assessment must be guided by the patient's ability to understand verbal instructions irrespective of his/her disorder. It is important to use the three levels

    Objective To identify the processes surgeons use to establish patient buy-in to postoperative treatments. Background Surgeons generally believe they confirm the patient's commitment to an operation and all ensuing postoperative care, before surgery. How surgeons get buy-in and whether patients participate in this agreement is unknown. Methods We used purposive sampling to identify three surgeons from different subspecialties who routinely perform high-risk operations at each of three distinct medical centers (Toronto, ON; Boston, MA; Madison, WI). We recorded preoperative conversations with three to seven patients facing high-risk surgery with each surgeon (n = 48) and used content analysis to analyze each preoperative conversation inductively. Results Surgeons conveyed the gravity of high-risk operations to patients by emphasizing the operation is “big surgery” and that a decision to proceed invoked a serious commitment for both the surgeon and the patient. Surgeons were frank about the potential for serious complications and the need for intensive care. They rarely discussed the use of prolonged life-supporting treatment, and patients’ questions were primarily confined to logistic or technical concerns. Surgeons regularly proceeded through the conversation in a manner that suggested they believed buy-in was achieved, but this agreement was rarely forged explicitly. Conclusions Surgeons who perform high-risk operations communicate the risks of surgery and express their commitment to the patient's survival. However, they rarely discuss prolonged life-supporting treatments explicitly and patients do not discuss their preferences. It is not possible to determine patients’ desires for prolonged postoperative life support based on these preoperative conversations alone. PMID:24253139

    Women undergo breast reconstruction at different time-points in their cancer care; knowing patients' preoperative quality of life (QoL) is critical in the overall care of the patient with breast cancer. Our objective was to describe presurgical QoL among women undergoing immediate, delayed, or major revision breast reconstructive surgery at our institution. From March 2008 to February 2009, we administered preoperative BREAST-Q questionnaires to women who presented to our institution for breast reconstruction. Univariate and multivariate analyses were performed to compare patient cohorts across multiple QoL domains including body image, physical well-being, psychosocial well-being, and sexual well-being. Of the 231 patients who presented for preoperative consultation, 176 returned the questionnaire (response rate 76%; 117 from the immediate, 21 from the delayed, and 32 from the major revision reconstruction groups, plus 6 mixed or unknown). The three groups differed significantly (P < 0.05) across four of the six domains: body image (satisfaction with breasts), psychosocial well-being, sexual well-being, and physical well-being of the chest and upper body. The immediate reconstruction group had higher (better) scores than the delayed reconstruction group, which had higher (better) scores than the major revision group. These data suggest that women presenting for breast reconstruction at different stages of reconstruction have different baseline QoL. Such data may help us better understand patient selection, education, and expectations, and may lead to improved patient-surgeon communication. Copyright © 2013 Wiley Periodicals, Inc.

    Little is known about the accuracy of reporting of preoperative narcotic utilization in spinal surgery. As such, the purpose of this study is to compare postoperative narcotic consumption between preoperative narcotic utilizers who do and do not accurately self-report preoperative utilization. Patients who underwent anterior cervical discectomy and fusion, minimally invasive lumbar discectomy, or minimally invasive transforaminal lumbar interbody fusion procedures between 2013 and 2014 were prospectively identified. The accuracy of self-reporting preoperative narcotic consumption was determined utilizing the Illinois Prescription Monitoring Program. Total inpatient narcotic consumption during postoperative Days 0 and 1 was compared according to the demographics and preoperative narcotic reporting accuracy. Similarly, the proportion of patients who continued to be dependent on narcotic medications at each postoperative visit was compared according to the demographics and preoperative narcotic reporting accuracy. A total of 195 patients met the inclusion criteria. Of these, 25% did not use narcotics preoperatively, while 47% and 28% did do so with accurate and inaccurate reporting, respectively. Patients who used narcotics preoperatively were more likely to demonstrate elevated inpatient narcotic consumption (adjusted RR 5.3; 95% CI 1.4-20.1; p = 0.013). However, such patients were no more or less likely to be dependent on narcotic medications at the first (p = 0.618) or second (p = 0.798) postoperative visit. Among patients who used narcotics preoperatively, no differences were demonstrated in terms of inpatient narcotic consumption (p = 0.182) or narcotic dependence following the first (p = 0.982) or second (p = 0.866) postoperative visit according to the self-reported accuracy of preoperative narcotic utilization. The only preoperative factors that were independently associated with elevated inpatient narcotic consumption were workers' compensation status and

    PurposeTo investigate the incidence and preoperative clinical features of reactivated Graves' orbitopathy (GO) after orbital decompression.MethodsThis study included patients with GO who underwent orbital decompression for disfiguring proptosis and not compressive optic neuropathy and received postoperative follow-up care for more than 12 months. Patients who experienced active inflammatory signs within 6 months of decompression were excluded from analysis. The demographic characteristics, ophthalmic manifestations, and biochemical parameters of the patients were analyzed for association with reactivation of GO by logistic regression analysis.ResultsOut of the 92 patients included in this study, seven (7.6%) experienced reactivation of GO after orbital decompression. The mean time interval between surgery and reactivation of GO was 36.3±14.3 weeks. Univariate logistic regression analysis identified age, existing smoking habits, and modified NOSPECS and Gorman scores as significant factors for the reactivation of GO. The results of multivariate logistic regression analysis revealed that smoking and modified NOSPECS and Gorman scores were associated with the reactivation of GO.ConclusionsQuitting smoking is important for the prevention of reactivation of GO after orbital decompression. Patients with severe symptoms, especially those with restrictive myopathy, should be carefully monitored for reactivation of GO after orbital decompression.

    Patients with suspected or symptomatic cardiac disease, associated with increased peri-operative risk, are often seen by anaesthetists in the pre-assessment clinic. The use of transthoracic echocardiography in this setting has not been reported. This prospective observational study investigated the effect of echocardiography on the anaesthetic management plan in 100 patients who were older than 65 years or had suspected cardiac disease. Echocardiography was performed by an anaesthetist, and was validated by a cardiologist. Overall, the anaesthetic plan was changed in 54 patients. Haemodynamically significant cardiac disease was revealed in 31 patients, resulting in a step-up of treatment in 20 patients, including: cardiology referral (four patients); altered surgical (two) and anaesthetic (four) technique; use of invasive monitoring (13); planned use of vasopressor infusion (10); and postoperative high dependency care (five). Reassuring negative findings in 69 patients led to a step-down in treatment in 34 patients: altered anaesthetic technique (six); procedure not cancelled (10); cardiology referral not made (10); use of invasive monitoring not required (seven); and high dependency care not booked (11). We conclude that focused transthoracic echocardiography in the pre-operative clinic is feasible and frequently alters management in patients with suspected cardiac disease.

    The value and impact of process improvement initiatives are difficult to quantify. We describe the use of time-driven activity-based costing (TDABC) in a clinical setting to quantify the value of process improvements in terms of cost, time and personnel resources. Difficulty in identifying and measuring the cost savings of process improvement initiatives in a Preoperative Assessment Center (PAC). Use TDABC to measure the value of process improvement initiatives that reduce the costs of performing a preoperative assessment while maintaining the quality of the assessment. Apply the principles of TDABC in a PAC to measure the value, from baseline, of two phases of performance improvement initiatives and determine the impact of each implementation in terms of cost, time and efficiency. Through two rounds of performance improvements, we quantified an overall reduction in time spent by patient and personnel of 33% that resulted in a 46% reduction in the costs of providing care in the center. The performance improvements resulted in a 17% decrease in the total number of full time equivalents (FTE's) needed to staff the center and a 19% increase in the numbers of patients assessed in the center. Quality of care, as assessed by the rate of cancellations on the day of surgery, was not adversely impacted by the process improvements. © 2013 Published by Elsevier Inc.

    The purpose of this study was to validate a virtual reality software for the recording of anthropometric measurements as a first step towards matching donors with recipients in the preoperative planning process which precedes the harvest of a facial allograft. Anthropometric measurements of both soft and bone tissue were recorded in 5 cryopreserved human heads to compare conventional analogue measurements with digital measurements obtained from 3-dimensional (3D) reconstructions produced using AYRA software. To test the degree of correlation between both measuring methods, intraclass correlation coefficient (ICC) was applied to each pair of measurements. ICCs calculated were greater than 0.6 (substantial or almost perfect correlation) for all of the pairs of variables, with the exception of 2 of the measurements studied in bone tissue. In facial transplantation, preoperative planning is crucial to select an allograft whose anatomical compatibility with the recipient defect is as close as possible. The dimensions of the potential face donor must be congruent to ensure the procedure's feasibility and the adequate insertion of the allograft into the defect. The recording of anthropometric measurements with the virtual reality software displayed an equivalent correlation to those produced using a conventional analogue method. The 3D reconstructions obtained by using a virtual reality software can play a useful role to facilitate the characterization of the donor face.

    Objective Preoperative endovascular embolization of intracranial tumors is performed to mitigate anticipated intraoperative blood loss. Although the usage of a wide array of embolic agents, particularly polyvinyl alcohol (PVA), has been described for a variety of tumors, literature detailing the efficacy, safety and complication rates for the usage of Onyx is relatively sparse. Materials and Methods We reviewed our single institutional experience with pre-surgical Onyx embolization of extra-axial tumors to evaluate its efficacy and safety and highlight nuances of individualized cases. Results Five patients underwent pre-surgical Onyx embolization of large or giant extra-axial tumors within 24 hours of surgical resection. Four patients harbored falcine or convexity meningiomas (grade I in 2 patients, grade II in 1 patient and grade III in one patient), and one patient had a grade II hemangiopericytoma. Embolization proceeded uneventfully in all cases and there were no complications. Conclusion This series augments the expanding literature confirming the safety and efficacy of Onyx in the preoperative embolization of extra-axial tumors, underscoring its advantage of being able to attain extensive devascularization via only one supplying pedicle.

    Purpose. To evaluate the potential of uterine artery embolization to minimize blood loss and facilitate easier removal of fibroids during subsequent myomectomy. Methods. This retrospective study included 22 patients (median age 37 years), of whom at least 15 wished to preserve their fertility. They presented with at least one fibroid (mean diameter 85.6 mm) and had undergone preoperative uterine artery embolization (PUAE) with resorbable gelatin sponge. Results. No complication or technical failure of embolization was identified. Myomectomies were performed during laparoscopy (12 cases) and laparotomy (9 cases). One hysterectomy was performed. The following were noted: easier dissection of fibroids (mean 5.6 per patient, range 1-30); mean intervention time 113 min (range 25-210 min); almost bloodless surgery, with a mean peroperative blood loss of 90 ml (range 0-806 ml); mean hemoglobin pretherapeutically 12.3 g/dl (range 5.9-15.2 g/dl) and post-therapeutically 10.3 g/dl (range 5.6-13.3 g/dl), with no blood transfusion needed. Patients were discharged on day 4 on average and the mean sick leave was 1 month. Conclusion. Preoperative embolization is associated with minimal intraoperative blood loss. It does not increase the complication rate or impair operative dissection, and improves the chances of performing conservative surgery.

    Chemical thromboprophylaxis in total hip arthroplasty (THA) may increase surgical site bleeding. The drug dose and timing of such therapy is therefore important. We studied two cohorts of 298 and 301 patients undergoing THA. The first group received their first dose of dalteparin sodium 5000 IU subcutaneously the evening before surgery and the second group a half dose six hours postoperatively, followed by 5000 units daily in both groups. Blood loss was reduced by 146 ml from 1230 ml to 1084 ml (p<0.001) with postoperative prophylaxis alone. The number of patients receiving blood transfusion decreased from 53% to 35% (p=0.001), and the use of transfused packed red blood cells was reduced from 1.25 to 0.83 units per patient (p=0.001). The overall rates of non-vascular complications 6 months after surgery were 12% and 11%, bleeding related events 6.0% and 4.0%, and thromboembolic related events were 2.0% and 2.3% in the preoperative and the postoperative cohorts. Two patients died in the preoperative group and one in the postoperative group due to venous and arterial thromboembolism. This study show that 2500 IU dose of dalteparin started 6 hours after surgery significantly reduced blood loss and transfusions compared to 5000 IU dalteparin injected 12 hours before surgery. Few thromboembolic events occurred, and these were equally distributed.

    During surgical treatment of pheochromocytoma,`haemodynamic instability may occur. To prevent this, patients receive preoperative treatment with an alpha-blocker. Nowadays, some centres use phenoxybenzamine, while others use doxazosin. The purpose of this review is to analyse the current evidence of the benefits and risks of phenoxybenzamine and doxazosin in the preoperative treatment of pheochromocytoma. The literature was reviewed by searching PubMed using the following search terms: pheochromocytoma, phenoxybenzamine, doxazosin and alpha-blockade. The filter was set on English language. No randomised controlled trials were found. Five follow-up studies comparing phenoxybenzamine and doxazosin in the treatment of pheochromocytoma were retrieved and analysed. There was a trend that systolic arterial pressure is slightly better controlled by phenoxybenzamine. However, this resulted in more pronounced postoperative hypotension as well. The use of an alpha-blocker was often accompanied by other vasoactive agents. phenoxybenzamine was often accompanied by a beta-blocker to control reflex tachycardia, while patients on doxazosin received significantly more additional antihypertensive medicines. Most of the studies showed that the use of vasoactive drugs and fluid infusion does not differ significantly between the two drugs. Phenoxybenzamine caused significantly more orthostatic hypotension, oedema and complaints of a stuffy nose. On the basis of the current evidence, there is no evidently superior alpha-blocker for the pretreatment of patients with pheochromocytoma. Perioperative haemodynamics seem to be slightly better controlled with phenoxybenzamine, at the cost of more pronounced postoperative hypotension. Side effects occurred less often in the doxazosin group.

    Hepatocellular carcinoma (HCC) is the most common liver cancer and the third leading cause of cancer-related death worldwide.1 Resection or liver transplantation may be curative in patients with early-stage HCC but early recurrence is common.2, 3 Microvascular invasion (MVI) is one of the most important predictors of early recurrence.3 The identification of MVI prior to surgery would optimally select patients for potentially curative resection or liver transplant. However, MVI can only be diagnosed by microscopic assessment of the resected tumor. The aim of the present study is to apply CT-based texture analysis to identify pre-operative imaging predictors of MVI in patients with HCC. Texture features are derived from CT and analyzed individually as well as in combination, to evaluate their ability to predict MVI. A two-stage classification is employed: HCC tumors are automatically categorized into uniform or heterogenous groups followed by classification into the presence or absence of MVI. We achieve an area under the receiver operating characteristic curve (AUC) of 0.76 and accuracy of 76.7% for uniform lesions and AUC of 0.79 and accuracy of 74.06% for heterogeneous tumors. These results suggest that MVI can be accurately and objectively predicted from preoperative CT scans.

    Malnourished patients with gastrointestinal tumours are at risk for postoperative complications and death. The aim of this study was to determine which nutritional assessment method better predicts outcome. Seventy-four patients, 45 men and 29 women; mean (SD) age of 63 (102) yr (range = 34 to 83), undergoing surgical resections for esophageal (n = 19) gastric (n = 43) and pancreatic (n = 12) tumors were preoperatively assessed by Patient Generated Subjective Global Assessment, anthropometry, and by laboratory sampling. Forty-three (58%) of them were unnourished; 25 Subjective Global Assessment (SGA)-A, 34 SGA-B, and 15 SGA-C cases. Mean (SD) of dominant hand adductor pollicis muscle thickness (DAPM) was 13 (3.5) mm and mean (SD) serum albumin was 3.8 (0.5) g/dL. Mean (SD) hospital staying for patients who complicated and died was 34 (29) days and 23 (13) days for survivors (not significant); SGA-B cases were significantly associated with higher mortality (n = 12, P<0.001). Patients with a mean (SD) DAPM below 10.8 (3.7) mm died more frequently than those with a mean (SD) greater than 14 (3) mm (P < 0.001). None of the methods was significantly related to hospital stay, but receiver operating characteristic curves (95% confidence interval) for PG-SGA and DAPM thickness (0.75 and 0.74) reliably predicted mortality (P<0.001) and these methods may be used as preoperative parameter.

    The Global Burden of Disease ranks migraine headache among the most disabling of conditions, and in the United States, migraine headache is one of the top five causes of visits to the emergency room. As migraineurs turn to surgical treatment for relief, it is unknown how migraine frequency influences outcomes. In total, 488 patients prospectively completed the migraine headache questionnaires preoperatively and at least 11 months postoperatively. Patients were grouped into three cohorts based on migraine frequency of one to 14 per month (episodic), 15 to 29 per month (chronic), or at least daily (daily). Statistics were performed with paired t tests, linear regression, and analysis of variance with Tukey's honestly significant difference test. All groups experienced a significant benefit from surgery in terms of frequency, duration, and severity of migraine headache, and Migraine Headache Index. Patients experienced significantly different final outcomes based on their frequency cohort with respect to duration (p = 0.02), frequency (p < 0.0001), and Migraine Headache Index (p < 0.0001). However, when the preoperative score is controlled for, the only significant difference between cohorts occurred in Migraine Headache Index among daily migraineurs compared with episodic (p = 0.0003) and chronic (p = 0.0008) migraineurs. No other significant findings persisted. All cohorts, regardless of their frequency of migraine headache, achieved significant improvement in frequency, duration, severity, and Migraine Headache Index. The groups also achieved statistically different final outcomes, but no group benefits more than the other when improvement is quantified, and patients can expect similar relative improvement.

    Preoperative fasting aims at minimizing the risk of pulmonary aspiration. However, perioperative safety does not directly increase with the duration of total abstinence from food and liquids. The traditional principle "nil per os from midnight on", is based on insufficient data, overinterpretation and expert opinion. In fact, the total perioperative risk of a clinically relevant regurgitation of gastric content is low. Clear liquids are not stored within the stomach for a long time and in the healthy, a fasting period of 6 h allows the total passage of solid food. Identifying those patients with an increased risk of perioperative aspiration is still difficult. In particular, the impact of pregnancy, adipositas and diabetes, trauma, smoking, opioids and renal insufficiency has not been clarified. This lack of knowledge is reflected by national and international guidelines concerning preoperative fasting, which mention the "patient at risk" without defining it exactly. Abstention from clear liquids 2 h before and of solids 6 h before induction of anesthesia, is becoming increasingly more accepted. Feeding babies with breast milk appears to be tolerated 4 h before anesthesiological procedures.

    Objective: To assess whether preoperative pentazocine can reduce intraoperative hemodynamic changes and postoperative pain. Methods: Fifty patients undergoing laparoscopic cholecystectomy were randomized into two groups. Group P received intravenous 0.5 mg/kg pentazocine 10 min before surgery, and Group C received normal saline as a placebo. A standardized general anesthesia was conducted in all patients. Mean blood pressure (MBP), heart rate (HR), and visual analog scale (VAS) scores at various time points were recorded. The tramadol consumption during the study period was recorded. Results: Group P had lower VAS scores at two, four, and eight hours postoperatively compared with Group C. MBP and HR rose significantly because of pneumoperitoneum within Group C, and no significant changes were detected in MBP and HR within Group P. Tramadol doses given were statistically fewer in Group P. Conclusion: Preoperative intravenous pentazocine can decrease intraoperative hemodynamic changes and postoperative pain. PMID:28168126

    Preoperative anxiety is usually experienced by patients awaiting surgical procedures and it can negatively impact patient's outcome. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) is a questionnaire created to identify anxious patients and their need for information: it has been translated and validated in many languages because of its reliability and ease of completion. To date, no Italian version of the APAIS has been produced; our aim was to translate and validate the APAIS in Italian. We produced an Italian version of the APAIS and we administered it to 110 patients undergoing elective surgery; we explored its structure by factor analysis and its reliability by Cronbach's alpha. We analyzed its external validity by confronting it to the Spielberg's State-Trait Anxiety Inventory (STAI). Sensitivity, specificity, and positive and negative predictive values of the Italian version of the APAIS were determined. The Italian version of the APAIS confirmed the original structure of the questionnaire and its internal consistency; it well correlated with the STAI-Y1, the subscale of the STAI which explore the anxiety "state." An APAIS score of 14 was found as best cutoff to distinguish anxious and non-anxious patients. The Italian translation of the APAIS showed psychometric properties similar to the original version. Its reliability and its efficiency make it a powerful tool even in Italian population to detect anxiety and need for information.

    Preoperative radiological evaluation of the extent of local invasion in maxillary squamous cell carcinoma (SCC) is very important in planning curative surgery. The aim of this study was to examine the accuracy of preoperative radiological evaluation with magnetic resonance imaging (MRI) for the extent of local invasion in maxillary SCC. A retrospective study was conducted of 33 patients who underwent a maxillectomy for maxillary SCC. We compared the MRI findings for 18 structures around the maxillary sinus with intraoperative or postoperative pathological findings. Discrepancies were found between preoperative MRI findings and intraoperative or postoperative pathological findings for 22 patients (66.7%). Overall, the specificity, sensitivity, positive predictive value, and negative predictive value of MRI were 83.4%, 83.0%, 64.5%, and 90.4%, respectively. The receiver operating characteristic curve showed that MRI evaluation of the posterolateral structures including the pterygoid plate, pterygoid muscle, and infratemporal fossa had a lower area under the curve (0.614) and a significantly lower accuracy when compared with the other structures (P = 0.294, 95% confidence interval 0.405-0.822). In conclusion, as the accuracy of preoperative MRI evaluation of the posterolateral structures is low, careful evaluation of local extension to the posterolateral structures is needed when planning curative surgery for maxillary SCC.

    Weight loss depends directly on the adhesion to the postoperative diet in patients undergoing a sleeve gastrectomy. The aim of this study is to evaluate the effect of different preoperative feeding patterns and the adhesion to a preoperative diet on short and mid- term postoperative weight loss. A prospective study of all morbidly obese patients undergoing a laparoscopic sleeve gastrectomy as a bariatric procedure between 2008 and 2012 was performed. Preoperative feeding patterns and weight loss, preoperatively and postoperatively at 12 and 24 months, were evaluated. A total of 50 patients were included, with a mean preoperative BMI of 51,2+7,9 kg/m(2). All the patients presented a feeding pattern of big eaters, 44% of snackers, 40% of sweet eaters and 48% reported regular ingestion of «light» soft drinks. Mean preoperative excess weight loss (EWL) was 13,4% (range 10-31,4%). At 12 months mean EWL was 83,7% and at 24 months 82,4%. Pre and postoperative EWL showed a direct correlation at 12 and 24 months. Mean EWL was significantly lower in snackers, sweet eaters and those drinking «light» soft drinks regularly. Preoperative weight loss correlates directly with postoperative weight loss at 1 and 2 years. Snackers, sweet eaters and «light» soft drink consumers, associated with a big eater pattern, achieve a significantly lower postoperative weight loss. Copyright © 2014 AEC.

    Preoperative anxiety is a very common phenomenon that adversely affects a patient's physical and psychological outcome. To evaluate subjective complaints such as anxiety, use of a validated psychological instrument is essential. In this study, we translated, culturally adapted and validated the Amsterdam preoperative anxiety and information scale (APAIS) for use in Japan. One hundred and twenty-six preoperative patients participated in this cross-sectional study. The psychometric properties of the APAIS evaluated by factor analysis, correlation with the state-trait anxiety inventory (STAI) and Cronbach's alpha were very similar to those of the original Dutch and English versions. Female gender and a high information requirement were associated with high preoperative anxiety. In conclusion, the Japanese version of the APAIS is a valid and reliable instrument for screening Japanese patients for preoperative anxiety and information requirements. Female gender and high information requirement may be associated with high preoperative anxiety.

    [Purpose] After an anterior cruciate ligament injury and subsequent reconstruction, quadriceps muscle weakness and disruption of proprioceptive function are common. The purpose of this study was to examine the effects of a 4 weeks preoperative exercise intervention on knee strength power and function post-surgery. [Subjects and Methods] Eighty male patients (27.8±5.7 age), scheduled for reconstruction surgery, were randomly assigned to two groups, the preoperative exercise group (n=40) and a no preoperative exercise group (n=40). The preoperative exercise group participated in a 4-week preoperative and 12-week post-operative programs, while the no preoperative exercise group participated only in the 12-week postoperative exercise program. Isokinetic measured of quadriceps strength were obtained at 4 weeks before and 3 months after surgery. [Results] The knee extensor strength deficits measured at 60°/s and 180°/s was significantly lower in the preoperative exercise group compared with the no preoperative exercise group. At 3 months after surgery, the extensor strength deficit was 28.5±9.0% at 60°/sec and 23.3±9.0% at 180°/sec in the preoperative exercise group, whereas the no preoperative exercise group showed extensor strength deficits of 36.5±10.7% and 27.9±12.6% at 60°/sec and 180°/sec, respectively. The preoperative exercise group demonstrated significant improvement the single-leg hop distance. [Conclusion] Four week preoperative exercise may produce many positive effects post reconstruction surgery, including faster recovery of knee extensor strength and function, as measured by single-leg hop ability.

    Retrospective case series. To clarify how preoperative global sagittal imbalance influences outcomes in patients with cervical compression myelopathy undergoing cervical laminoplasty. The influence of sagittal balance on outcomes of cervical laminoplasty remains uncertain. The authors retrospectively reviewed data of 106 patients who underwent double-door cervical laminoplasty between 2004 and 2011 and investigated the influence of the C7 sagittal vertical axis (SVA) on outcome scores. Primary outcomes used were Japanese Orthopedic Association (JOA) scores, Numerical Rating Scale for neck or arm pain, the Short Form 36 Health Survey (physical and mental component summary scores ), and the Neck Disability Index (NDI). Ninety-two patients with complete data were eligible for inclusion. The preoperative C7 SVA was ≤5 cm in 64 patients (69.6%) and > 5 cm in 28 (30.4%). We compared each parameter by the magnitude of spinal sagittal balance (preoperative C7 SVA > 5 cm vs. C7 SVA ≤ 5 cm) after adjusting for age via the least square mean analysis because the average age was significantly higher in patients with C7 SVA > 5 cm. As for the radiographic parameters, both C2-7 SVA and C7 SVA were larger in patients when the C7 SVA was > 5 cm. Numerical Rating Scale for postoperative arm pain, postoperative JOA scores, and both pre- and postoperative physical component summary and NDI were worse in patients with C7 SVA > 5 cm; however, the JOA score recovery rate and changes in physical component summary and NDI were not significantly different. Postoperative functional outcome scores were significantly lower in patients with C7 SVA > 5 cm, although the improvement after cervical laminoplasty was not greatly affected. The involvement of global sagittal balance and cervical regional alignment should be considered in evaluating surgical outcomes for patients undergoing cervical laminoplasty. 4.

    ABSTRACT Introduction After a failed transplant, management of a non-functional graft with pain or recurrent infections can be challenging. Transplant nephrectomy (TN) can be a morbid procedure with the potential for significant blood loss. Embolization of the renal artery alone has been proposed as a method of reducing complications from an in vivo failed kidney transplant. While this does yield less morbidity, it may not address an infected graft or refractory hematuria or rejection. We elected to begin preoperative embolization to assess if this would help decrease the blood loss and transfusion rate associated with TN. Materials and Methods We performed a retrospective analysis of all patients who underwent non-emergent TN at our institution. Patients who had functioning grafts that later failed were included in analysis. TN was performed for recurrent infections, pain or hematuria. We evaluated for blood loss (EBL) during TN, transfusion rate and length of hospital stay. Results A total of 16 patients were identified. Nine had preoperative embolization or no blood flow to the graft prior to TN. The remaining 7 did not have preoperative embolization. The shortest time from transplant to TN was 8 months and the longest 18 years with an average of 6.3 years. Average EBL for the embolized patients (ETN) was 143.9cc compared to 621.4cc in the non-embolized (NETN) group (p=0.041). Average number of units of blood transfused was 0.44 in the ETN with only 3/9 patients requiring transfusion. The NETN patients had average of 1.29 units transfused with 5/7 requiring transfusion. The length of stay was longer for the ETN (5.4 days) compared to 3.9 in the NETN. No intraoperative complications were seen in either group and only one patient had a postoperative ileus in the NETN. Conclusion Embolization prior to TN significantly decreases the EBL but does not significantly decrease transfusion rate. However, patients do require a significantly longer hospitalization with

    Continuous home monitoring of oxygen saturation has become a reliable and feasible practice. The objective of this study was to investigate the role of preoperative overnight oximetry in predicting postoperative adverse events. Following research ethics board approval, consented patients underwent a preoperative overnight monitoring of oxygen saturation with a portable oximeter. Parameters from the oximetry data were extracted and their predictive performance for postoperative adverse events was evaluated. A total of 573 patients were studied with age: 60±12 years and 45% male. Oxygen desaturation index (ODI), cumulative time percentage with SpO2 <90% (CT90) and mean SpO2 were identified as significant predictors for postoperative adverse events. The privilege sensitivity, optimal predictive and privilege specificity cut-offs were: ODI: >3.0 events/h, >9.2 events/h and > 28.5 events/h; CT90: >0.1%, >1.1% and >7.2%; mean SpO2: <96.2%, <94.6% and <92.7%. The odds ratio for corresponding optimal cut-offs was: ODI 1.9 (95% CI: 1.4,2.7); CT90: 1.7 (95% CI: 1.2,2.4) and mean SpO2: 2.7 (95% CI: 1.9,3.8). The patients classified as high risk by ODI or CT90 or mean SpO2 had a significantly higher rate of postoperative adverse events. For ODI >28.5 vs. ODI ⋝28.5 events/h, the odds ratio adjusted with age, gender, body mass index and American Society of Anesthesiologists physical status was 2.2 (95% CI: 1.3-3.9). Patients with mean preoperative overnight SpO2 <92.7% or ODI >28.5 events/h or CT90 >7.2% are at higher risk for postoperative adverse events. Overnight oximetry could be a useful tool to stratify patients for the risk of postoperative adverse events.

    Given a 10% malignancy rate in pediatric ovarian masses, what preoperative factors are helpful in distinguishing those at higher risk to risk stratify accordingly? After institutional review board approval (IRB#022008-095), a 15(1/2)-year retrospective review of operative ovarian cases was performed. A total of 424 patients were identified, with a mean age 12.5 years (range, 1 day to 19 years), without an age disparity between benign (12.54 years, 89%) and malignant (11.8 years, 11%) cases. The 1- to 8-year age group had the highest percentage of malignancies (22%; odds ratio [OR], 3.02; 95% confidence interval [CI], 1.33-6.86). A chief complaint of mass or precocious puberty versus one of pain had an OR for malignancy of 4.84 and 5.67, respectively (95% CI, 2.48-9.45 and 1.60-20.30). Imaging of benign neoplasms had a mean size of 8 cm (range, 0.9-36 cm) compared with malignancies at 17.3 cm (6.2-50 cm, P < .001). An ovarian mass size of 8 cm or longer on preoperative imaging had an OR of 19.0 for malignancy (95% CI, 4.42-81.69). Ultrasound or computed tomographic findings of a solid mass, although infrequent, were most commonly associated with malignancy (33%-60%), compared with reads of heterogeneous (15%-21%) or cystic (4%-5%) lesions. The malignancies (n = 46) included germ cell (50%, n = 23), stromal (28%, n = 13), epithelial (17%, n = 8), and other (4%, n = 2). Tumor markers obtained in 71% of malignancies were elevated in only 54%, whereas 6.5% of those sent in benign cases were similarly elevated. Elevated beta-human chorionic gonadotropin (beta-HCG), alpha fetoprotein (alphaFP), and cancer antigen 125 (CA-125) were significantly associated with malignancy (P < .02) and an elevated carcinoembryonic antigen (CEA) was not (P = .1880). This reported series of pediatric ovarian masses demonstrates that preoperative indicators that best predict an ovarian malignancy are a complaint of a mass or precocious puberty, a mass exceeding 8 cm or a mass with solid

    Obstructive sleep apnea is a major complication of pharyngeal flap surgery. The purpose of the present study is to predict preoperatively the risk of upper airway obstruction after surgery. We performed an overnight sleep study preoperatively and postoperatively in 16 pediatric patients considered for pharyngeal flap surgery. Preoperative sleep study was done for two nights, once in normal breathing condition and once with complete nasal occlusion by packing of nostril with tampon gauze. In preoperative sleep recordings in normal breathing condition, all subjects had a normal apnea hypopnea index (AHI) less than 5/h. In preoperative recording with complete nasal occlusion, five patients exceeded 5/h in AHI. In particular, for two patients who had AHI higher than 15/h, we gave up a surgery in one case and performed pharyngeal flap operation for the other following a tracheotomy for severe disturbance of oral breathing. The remaining 14 subjects underwent surgery without airway obstructive complications. There was strong correlation between preoperative AHI with nasal tampon gauze and AHI at two weeks postoperatively (r = 0.88 P < .0001). There was no significant correlation between preoperative AHI in normal breathing condition and postoperative AHI (P > .05). These results exhibit preoperative sleep study with complete nasal airway occlusion represent postoperative breathing condition well during early postoperative period. Preoperative sleep study with complete nasal airway occlusion with nasal tampons could be useful for predicting the risk of upper airway obstruction secondary to pharyngeal flap surgery.

    Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

    Preoperative anxiety is not systematically assessed during premedication appointments, although it may influence the postoperative course and outcome. The aim of this study was to assess preoperative anxiety in a sample of patients before major urological surgery and to characterize the impact on postoperative pain. An additional aim was to analyze the agreement between patients' self-ratings and physicians' anxiety ratings. In all, 127 male and 27 female patients participated in a prospective observational study. Preoperative anxiety was assessed with two validated instruments - the APAIS (Amsterdam Preoperative Anxiety and Information Scale) and the State Scale of the STOA questionnaire (State-Trait Operation Anxiety) - during the premedication appointment. Physicians provided their subjective ratings on patients' anxiety and need for information using the APAIS. The predictive value of preoperative anxiety for postoperative pain was evaluated. Nearly four out of ten patients were identified as "anxiety cases"; thereof women were more afraid than men were. Preoperative anxiety was not correctly assessed by physicians, who overestimated patients' anxiety. In female patients, preoperative anxiety was predictive of increased postoperative pain scores. Preoperative anxiety is a frequent concern and often not correctly assessed by physicians. The use of scoring systems to detect preoperative anxiety is useful in clinical routine and helps to decide on therapeutic interventions.

    As a rule continuous bony defects of the mandible after tumour resection are temporarily bridged with the AO reconstruction plate. To precontour the plate, CT-scans of the mandible at a scale of 1:1 6 mm above and parallel to the inferior margin are needed. Corresponding layers further cranial show the anatomy of the chin. Using a lateral cephalograph, the mandibular angle and the length of the plate in the ascending ramus are measured. Of the 19 preshaped reconstruction plates implanted, 11 did not need any intraoperative adjustment of shape. The other 8 plates needed only slight modifications of contour. Preoperative bending of the reconstruction plate reduces the time taken for the operation, protects the material and the plate is precisely shaped.

    In 8 healthy patients (ASA I-II) there was analyzed the effect of salbutamol over serum levels of potassium, glucose, insulin, AMPc and GMPc. Also were determined the arterial blood pressure and heart rate. The drug was administered intravenously, as bronchodilator, during the preoperative period. There was a significant decrease in kaliemia (p less than 0.001 immediately after receiving the salbutamol infusion and p less than 0.05 at 60 min). Their plasma potassium levels dropped from 4.03 +/- 25 to 3.45 +/- 0.16 mEq.l-1. The plasma levels of glucose and insulin increased with a significance of p less than 0.001 post salbutamol perfusion. There were no changes in the plasmatic AMPc and GMPc. Heart rate increased from 67 +/- 10.8 to 80.5 +/- 13.7 (p less than 0.01) post perfusion, returning afterwards to their basal values. Arterial blood pressure was unmodified.

    This represents the preoperational test report for the Primary Ventilation Condenser Cooling System, Project W-030. Project W-030 provides a ventilation upgrade for the four Aging Waste Facility tanks. The system uses a closed chilled water piping loop to provide offgas effluent cooling for tanks AY101, AY102, AZ1O1, AZ102; the offgas is cooled from a nominal 100 F to 40 F. Resulting condensation removes tritiated vapor from the exhaust stack stream. The piping system includes a package outdoor air-cooled water chiller with parallel redundant circulating pumps; the condenser coil is located inside a shielded ventilation equipment cell. The tests verify correct system operation and correct indications displayed by the central Monitor and Control System.

    SYNOPSIS Neuroendocrine tumors (NETs) are a diverse group of neoplasms that can arise in a variety of locations throughout the body and often metastasize early. A patient’s only chance for cure is surgical removal of the primary tumor and all associated metastases, although even when surgical cure is unlikely, patients can benefit from surgical debulking of their disease. A thorough preoperative workup will often require multiple clinical tests and imaging studies to locate the primary tumor, delineate the extent of the disease, and assess tumor functionality. This review will discuss the biomarkers important for the diagnosis of these unique tumors and the imaging modalities that are most helpful for surgical planning. PMID:26610781

    A retrospective study was undertaken to evaluate the role of digital subtraction angiography (DSA) in the surgical planning of musculoskeletal neoplasms. Thirteen patients with primary bone and soft-tissue tumors were examined by CT and DSA. Three patients also had conventional angiography. DSA yielded surgically useful information in 10 patients, comparable to that expected from conventional angiography. DSA was most helpful in demonstrating the presence or absence of major vessel involvement by tumor when this could not be ascertained definitely on CT. Demonstration of mass extent by CT was accurate in 11 patients. Results of this study suggest that the combination of CT and DSA is useful in the preoperative evaluation of selected extremity tumors and should diminish the need for conventional angiography.

    Object In this study the role of magnetic source imaging for preoperative motor mapping was evaluated by using a single-dipole localization method to analyze motor field data in 41 patients. Methods Data from affected and unaffected hemispheres were collected in patients performing voluntary finger flexion movements. Somatosensory evoked field (SSEF) data were also obtained using tactile stimulation. Dipole localization using motor field (MF) data was successful in only 49% of patients, whereas localization with movement evoked field (MEF) data was successful in 66% of patients. When the spatial distribution of MF and MEF dipoles in relation to SSEF dipoles was analyzed, the motor dipoles were not spatially distinct from somatosensory dipoles. Conclusions The findings in this study suggest that single-dipole localization for the analysis of motor data is not sufficiently sensitive and is nonspecific, and thus not clinically useful.

    Pancreatic cystic neoplasms (PCNs) are a diverse group of neoplasms in the pancreas, and are more increasingly encountered with widespread abdominal screening and improved imaging techniques. The most common types of PCNs are serous cystic neoplasms (SCNs), mucinous cystic neoplasms (MCNs), and intraductal papillary mucinous neoplasms (IPMNs). Clinicians frequently feel bewildered in the differential diagnosis and subsequent management among the various types of lesions in the pancreas, which may lead to overtreatment or delayed treatment. The current review provides recent developments in the understanding of the three most common types of PCNs, the latest modalities used in preoperative diagnosis and differential diagnosis, as well as the most up to date management. Suggestions for diagnosis and differential diagnosis of SCNs, MCNs, and IPMNs are also provided for young surgeons. Better understanding of these neoplasms is essential for clinicians to make accurate diagnosis and to provide the best management for patients. PMID:23463761

    Based on a review of the literature on resectable lung cancer, pulmonary risk factors before, during and after surgery are discussed. The role of preoperative evaluation in order to determine the patient ability to withstand radical resection is considered. Spirometric indexes as forced expired volume (FEV1) and diffusing lung carbon monoxide capacity (DLCO) should be measured first. If FEV1 and DLCO are > 60% of predicted, patients are at low risk for complications and can undergo pulmonary resection. However, if FEV1 and DLCO are <60% of predicted, further evaluation with a quantitative lung scan is required. If predicted postoperative values for FEV1 and DLCO are >40%, patients can undergo lung resection, otherwise exercise testing is necessary. If the latter shows maximal oxygen uptake (VO2max) of > 15ml/Kg, surgery can be performed; if VO2max is <15 ml/Kg, patients are inoperable.

    The pelvic support osteotomy is a double level femoral osteotomy with the objective of eliminating a Trendelenburg and short limb gait in young patients with severe hip joint destruction as a consequence of neonatal septic arthritis. The osteotomy has seen several changes and a brief historical overview is provided to set the evolution of the modifications of the procedure in context. We present an analysis of the preoperative assessment that will assist the surgeon to plan out the procedure. Specifically, we set out to answer the following questions: (a) Where should the first osteotomy be performed and what is the magnitude of valgus and extension correction desired at this level? (b) Where should the second osteotomy be performed and what is the magnitude of varus and derotation desired at this level? PMID:18758686

    Breast-conserving surgery (BCS) is the treatment of choice for early breast cancer. The adequacy of surgical margins (SM) is a crucial issue for adjusting the volume of excision and for avoiding local recurrences, although the precise definition of an adequate margins width remains controversial. Moreover, other factors such as the biological behaviour of the tumor and subsequent proper systemic therapies may influence the local recurrence rate (LRR). However, a successful BCS requires preoperative localization techniques or margin assessment techniques. Carbon marking, wire-guided, biopsy clips, radio-guided, ultrasound-guided, frozen section analysis, imprint cytology, and cavity shave margins are commonly used, but from the literature review, no single technique proved to be better among the various ones. Thus, an association of two or more methods could result in a decrease in rates of involved margins. Each institute should adopt its most congenial techniques, based on the senologic equipe experience, skills, and technologies. PMID:23986868

    This study aimed to investigate how both visual analog scale cutoff scores and State-Trait Anxiety Inventory scores relate to hemodynamic changes in patients entering the operating theater. A prospective observational study. The study subjects included 130 prospectively enrolled patients who were scheduled for abdominal surgery under combined epidural-general anesthesia and who underwent preoperative anxiety level measurements using both scales. The heart rate and systolic blood pressure on entering the operating theater were significantly higher than those at baseline in the high and low/moderate anxiety groups. Variations in heart rate and systolic blood pressure were significantly higher, whereas peripheral blood flow was significantly lower in the high anxiety group compared with the low/moderate anxiety group. Using the visual analog scale to measure anxiety can improve our understanding of the hemodynamic changes that occur when patients enter the operating theater.

    Preoperative embolization has the potential to decrease intraoperative blood loss and facilitate spinal cord decompression and tumor resection. We report our institutional experience with the embolization of hypervascular extradural spinal tumors with Onyx as well as earlier embolic agents in a series of 28 patients. A retrospective case review was conducted on patients undergoing preoperative transarterial embolization of a spinal tumor between 1995 and 2012 at our institution. Twenty-eight patients met the inclusion criteria, with a mean age of 60.6 years. Twenty-eight patients had metastatic tumors. In 14 (50%) patients the metastases were from renal cell carcinomas. Fifty-four vessels were embolized using PVA, NBCA, Onyx, coils, or embospheres. Sixteen patients were treated with Onyx, 6 patients with PVA, 3 patients with embospheres, 2 patients with NBCA, and 3 patients with a combination of embolic agents. The average decrease in tumor blush was 97.8% with Onyx versus 92.7% with the rest of the embolic agents (p=0.08). The estimated blood loss was 1616ml (range 350-5000ml). Blood loss was 750cm(3) on average with Onyx versus 1844 with the rest of the embolic agents (p=0.14). The mean length of stay was 16 days. The mortality rate was zero. Pre- and post-operative modified Rankin Score (mRS) did not differ significantly in the series (3.12 versus 3.10, respectively, p=0.9). In our experience, the use of transarterial tumor embolization as an adjunct for spinal surgery is a safe and feasible option. Copyright © 2013 Elsevier B.V. All rights reserved.

    ABSTRACT Objective: In recent years, various investigators have shown considerable interest in the use of macrolide antibiotics for treatment of chronic rhinosinusitis and nasal polyposis. The aim of this study was to evaluate the clinical effects of preoperative long-term, low-dose clarithromycin administration in patients with nasal polyposis. Methods: Eighty nasal polyp patients (42 non-atopic and 38 atopic) were included in this prospective, non-placebo controlled investigation and randomized equally to either the combined clarithromycin-surgical or surgical group. Forty patients received 500 mg of clarithromycin daily for eight weeks, and, after evaluation, they were treated by functional endoscopic sinus surgery (FESS). The other 40 patients were treated only surgically. The nasal symptom scores and endoscopic scores after macrolide treatment/surgical treatment, and after six and 12 months of follow-up were evaluated. Results: After clarithromycin therapy, we found improvement in symptom scores in 25/40, and improvement in endoscopic scores in 19/40 patients. We found no significant difference in nasal symptom score between allergic and non-allergic patients regarding the outcome to macrolide (p = 0.352) or surgical treatment (p = 0.396). When we compared differences between endoscopic scores at the time points of 12 months and six months postoperatively (ESt12 minus ESt6), we found statistically lower differences in the clarithromycin-surgery group than in the surgery group (p = 0.006). Conclusion: Preoperative clarithromycin administration postponed nasal polyp relapse after FESS. Allergies have no influence on the clinical efficacy of clarithromycin therapy and on the efficacy of FESS. PMID:25867579

    The purpose of this study was to evaluate the kinematic changes that occur about the foot and ankle during gait in patients with degenerative joint disease (DJD). By comparing a normal adult population with what was found in the DJD population we determined how the motion of theses groups differed, thereby characterizing how this pathology affects foot and ankle motion. A 15-camera Vicon Motion Analysis System was used in conjunction with weight bearing radiographs to obtain three-dimensional motion of the foot and ankle during ambulation. The study was comprised of 34 patients and 35 ankles diagnosed with DJD (19 men and 15 women) of the ankle and 25 patients with normal ankles (13 men and 12 women). Dynamic foot and ankle motion was analyzed using the four-segment Milwaukee Foot Model (MFM). The data from this model resulted in three-dimensional (3D) kinematic parameters in the sagittal, coronal, and transverse planes as well as spatial-temporal parameters. Patient health status was evaluated using the SF-36 Health Survey and American Orthopaedics Foot and Ankle Society (AOFAS) hindfoot scores. The DJD group showed significant differences (p<0.001) as compared to normals with prolonged stance time, shortened stride length, reduced cadence and a walking speed which was only 66.96% of normal. Overall, kinematic data in the DJD cohort showed significant differences (p<0.001) in all planes of motion for tibial, hindfoot and forefoot motion as compared to normals. The average preoperative AOFAS hindfoot score was 26. DJD of the ankle results in decreased range of motion during gait. This decreased range of motion may be related to several factors including bony deformity, muscle weakness, and attempts to decrease the pain associated with weight bearing. To date there has not been a study which describes the effect of this disease process on motion of the foot and ankle. These findings may prove to be useful in the pre-operative assessment of these patients.

    Carbohydrate-rich liquid drinks (CRLDs) have been recommended to attenuate insulin resistance by shortening the preoperative fasting interval. The aim of our study the effect of preoperative oral administration of CRLDs on the well-being and clinical status of patients. A randomized, double blind, prospective study of patients undergoing open colorectal operations (CR) and open cholecyctectomy (CH) was conducted. Patients were divided into three groups: study, placebo, and control. Visual analogue scale (VAS) scores for seven parameters (thirst, hunger, anxiety, mouth dryness, nausea, weakness and sleep quality) were recorded and compared for two different time periods (up to 24 h postoperatively and from 36 to 48 h postoperatively). The Simplified Acute Physiology Score changes (SAPS)-II between the three groups were also studied. There were 142 patients American Society of Anesthesiology (ASA) I or II enrolled in the study (CR = 71 and CH = 71). There were no significant differences in postoperative SAPS-II scores or lengths of hospital stay (LOS) between the groups. However, in CR patients, the degree of thirst was partially improved by drinking CRLDs (P = 0.027). In CH patients, on the other hand, feelings of thirst, hunger, mouth dryness, nausea and weakness showed significant improvement (P < 0.05). Oral administration of carbohydrate-rich liquid drinks (CRLDs) improves the well-being in patients undergoing CH, but the effect is less evident in patients undergoing CR. No significant improvements were seen in clinical status or in length of hospital stay in either group. ANZCTR.org.au: ACTRN12614000995673 (registered on 16/09/2014).

    Salivary gland neoplasms account for only 3% of all tumors of the head and neck area, but as they represent a wide variety of histological types, they are a big diagnostic challenge. The cornerstone of salivary gland neoplasm treatment, both for the benign and malignant lesions, is surgery. The main goal of the therapy is not only to achieve complete surgical tumor resection, but also to preserve adjacent structures (facial nerve, parapharyngeal space structures). Ultrasonography is an examination commonly used in the preoperative diagnosis of the lesions localized within salivary glands. Very often it is the only diagnostic imaging method used in these cases. The aim of the study was to establish diagnostic value of US examination and its parameters for the assessment of parotid gland tumors. A prospective study was performed on a group of 51 patients with parotid gland neoplasms, who over a period of 3 years underwent surgery in Otolaryngology and Laryngological Oncology Department with Craniomaxillofacial Surgery Department of Central Clinical Hospital of Ministry of Defence in Warsaw. All the included patients underwent US examination in the preoperative period. The parameters selected for the assessment were: ill-defined tumor margins, tumor vascularity and the presence of enlarged regional lymph nodes. The results of imaging examination were compared to the final diagnosis based on pathological examination of the surgical specimen. The parameters of the US examination such as sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the evaluation of parotid gland tumors were established based on the examination results. An analysis was performed and ill-defined parotid tumor margins turned out to be a US parameter with higher diagnostic value for differentiating benign and malignant lesions than increased tumor vascularity. The presence of enlarged regional lymph nodes with blurred echostructure on the US examination

    It has been demonstrated that osteoarthritis (OA) is activity related and may worsen when joint contact stress becomes excessive due to overloading. Hence, joint alignment and loading are considered to be the key biomechanical determinants for OA. The initiation of pathologic changes in the knee has been described by the mechanism termed, "vicious cycle" in which joint axial malalignment creates excessive stresses to the localized joint cartilage/subchondral bone regions and the surrounding soft tissue which in turn produces more laxity and joint deformity and thus repeats the cyclic degradation mechanism. If this degenerative cycle can be broken with joint alignment surgery such as osteotomy, a procedure to realign the knee joint and thus redistribute joint forces applied to each compartment, performed properly and at the appropriate time, the osteoarthritic disease process can be decelerated and even reversed. The main goals of this paper are to emphasize the importance of accurate preoperative planning for osteotomy in order to properly correct joint alignment, and to justify the application of an existing computer program, OASIS (Osteotomy Analysis and Simulation Software) using plain radiographs to perform appropriate surgical planning. Normal subjects and knee osteotomy patients were studied to establish a database for the purpose of establishing the utility and efficacy of the presently proposed concept. We wish to rationalize knee osteotomy as a preferred and cost-effective treatment for patients with early symptoms of OA in the knee. This paper presents a new concept of preoperative planning for knee osteotomy based on the underlying etiology of the disease and biomechanical viewpoint with strong emphasis on surgical treatment rationales. The established principles in this paper can be applied to other joints of the body and will help implement preventive measures and other non-surgical means to manage patients with axial malalignment or early degenerative

    Post-operative pulmonary complications are a significant problem following open upper abdominal surgery. Preliminary evidence suggests that a single pre-operative physiotherapy education and preparatory lung expansion training session alone may prevent respiratory complications more effectively than supervised post-operative breathing and coughing exercises. However, the evidence is inconclusive due to methodological limitations. No well-designed, adequately powered, randomised controlled trial has investigated the effect of pre-operative education and training on post-operative respiratory complications, hospital length of stay, and health-related quality of life following upper abdominal surgery. The Lung Infection Prevention Post Surgery - Major Abdominal- with Pre-Operative Physiotherapy (LIPPSMAck POP) trial is a pragmatic, investigator-initiated, bi-national, multi-centre, patient- and assessor-blinded, parallel group, randomised controlled trial, powered for superiority. Four hundred and forty-one patients scheduled for elective open upper abdominal surgery at two Australian and one New Zealand hospital will be randomised using concealed allocation to receive either i) an information booklet or ii) an information booklet, plus one additional pre-operative physiotherapy education and training session. The primary outcome is respiratory complication incidence using standardised diagnostic criteria. Secondary outcomes include hospital length of stay and costs, pneumonia diagnosis, intensive care unit readmission and length of stay, days/h to mobilise >1 min and >10 min, and, at 6 weeks post-surgery, patient reported complications, health-related quality of life, and physical capacity. The LIPPSMAck POP trial is a multi-centre randomised controlled trial powered and designed to investigate whether a single pre-operative physiotherapy session prevents post-operative respiratory complications. This trial standardises post-operative assisted ambulation and

    Video-based patient information supplementing clinician interview has been shown to reduce anxiety and improve satisfaction in patients undergoing procedures. In Queensland more than 90% of caesarean sections are performed under regional anaesthesia. We aimed to assess the effect of using an information video about neuraxial blockade in patients having regional anaesthesia for elective caesarean section. Subjects were randomised to undergo usual care (Group C), or to view a video and undergo usual care (Group V). Subjects completed the Spielberger State-Trait Anxiety Inventory preoperatively and the Maternal Satisfaction with Caesarean Section Score questionnaire postoperatively. Satisfaction with, and duration of the preoperative anaesthetic interview, were noted. One-way analysis of variance (ANOVA) and Chi-squared tests were used in statistical analysis. One-hundred and forty three subjects were randomised and 110 completed the protocol and analysis. Group C and Group V were similar in terms demographic and anaesthesia data. There was no difference in anxiety score (41.2 versus 39.8, P=0.50), maternal satisfaction score (118.5 versus 122.7, P=0.22) or interview duration (16.3 versus 15.8 min, P=0.69) between the two gro
