    In daily practice, acute and chronic pulmonary diseases are common issues presenting to the anesthetist. Respiratory physiology in general is affected by both general and regional anesthesia, which results in an increased number of perioperative complications in pulmonary risk patients. Therefore, anesthetic management of patients with bronchial asthma needs to address different clinical topics: the physical appearance of pulmonary disease, type and extent of surgical intervention as well as effects of therapeutic drugs, anesthetics and mechanical ventilation on respiratory function. The present work describes important precautions in preoperative scheduling of the asthmatic patient. In the operative course, airway manipulation and a number of anesthetics are able to trigger intraoperative bronchial spasm with possibly fatal outcome. It is essential to avoid these substances to prevent asthma attack. If asthmatic status occurs, appropriate procedures according to therapeutic standards have to be applied to the patient. Postoperatively, sufficient pain therapy avoids pulmonary complications and improves outcome. PMID:27359239

    Glomus jugulare and vagale tumors present unique problems to both anesthesiologists and surgeons. The anesthetic plant must be tailored to each patient and provide hemodynamic stability, a consistent intraoperative environment, and rapid awakening after prolonged administration. In this report, we describe our anesthetic method used for paraganglioma resection, which utilizes a combination technique of low-dose isoflurane with a narcotic infusion initiated after bolus administration. Results from the last three patients anesthetized by this "balanced" technique were compared to a similar patient who received isoflurane anesthesia exclusively for a major portion of the surgical procedure. The patients receiving the balanced anesthesia required no hemodynamic support during the procedure and were awakened within 15 to 25 minutes of surgical completion. The patient receiving high-dose isoflurane, however, had a prolonged anesthetic wake-up time and did not follow verbal commands for approximately 12 hours after surgical completion. This patient also required hemodynamic support with a phenylephrine infusion during tumor resection. The balanced technique seems to be superior to a straight inhalational technique. Neurological assessment and intubation times after prolonged surgery were reduced with superb hemodynamic stability throughout. This anesthetic method produces a stable intraoperative environment and provides deep surgical anesthesia during periods when muscle relaxants cannot be utilized. PMID:17170932

    2016-06-01

    An increasing number of patients with a high risk for surgery because of advanced age and associated comorbidities that significantly increase the perioperative risk successfully undergo transcatheter aortic valve implantation (TAVI). TAVI is commonly performed under general or local anesthesia or local anesthesia plus mild sedation to achieve a conscious sedation. The anesthetic regimen generally depends on the patient's clinical profile and the procedural technical characteristics, but the center's experience and internal organization likely play an important role in anesthetic decision making. The large variation in anesthetic management among various centers and countries likely depends on the different composition of the operating team and institutional organization. Therefore, a tight interaction among the various members of the TAVI team, including the cardiac anesthetist, provides the proper anesthetic management using the chosen procedural technique.

    Mirror syndrome (Ballantyne syndrome, triple edema, maternal hydrops, pseudotoxemia) is a rarely diagnosed condition associated with pregnancy that can be life-threatening for both the mother and fetus. There is limited literature on its pathogenesis and anesthetic management, making prevention and treatment complex. The duration of pregnancy and severity of maternal or fetal presentation often determines outcome. We describe the anesthetic considerations of a morbidly obese parturient with Mirror syndrome.

    Takayasu arteritis is a rare chronic progressive panendarteritis involving the aorta and its main branches. Anesthesia in patients with this disease can be complicated by severe uncontrolled hypertension, end-organ dysfunction, and stenosis of major blood vessels. In this case, general anesthesia was induced with sevoflurane and remifentanil without complications. To prevent intraoperative complications, we conducted intubation with a rigid video laryngoscope with careful consideration of the concentrations of analgesics and sedatives used. This case demonstrates the importance of anesthetic techniques for maintaining adequate tissue perfusion without hemodynamic changes in the anesthetic management of patients with Takayasu arteritis.

    Anesthesia of the soft and hard tissues of the maxilla may require up to 5 injections. Thus, the aim of this study was to evaluate the anesthetic efficacy of the anterior middle superior alveolar (AMSA) and supraperiosteal injection techniques during subgingival scaling and root planing (SRP). Thirty individuals with periodontitis were scheduled for SRP on the buccal aspect of teeth in the anterior maxilla. Before SRP, on a randomly chosen side of the maxilla, the supraperiosteal injection was performed in 1 session, while the AMSA injection was conducted in the contralateral side of the same patient in another session. Immediately after each SRP session, patients rated their pain perception during the procedure with a visual analog scale. No statistically significant differences in mean pain ratings during SRP were found after both anesthetic techniques (P > .05). This preliminary study demonstrated that the AMSA and supraperiosteal injection techniques provided similar anesthetic comfort during SRP. The AMSA injection could be an alternative to anesthetize the buccal aspect of maxilla, without the undesirable effects on facial structures such as the upper lip, nostrils, and lower eyelids. However, further randomized clinical trials with larger samples are necessary to confirm such results. PMID:26650493

    Background Opioid pharmacotherapy is often used to treat cancer pain. However, morphine and other opioid-like substance use in patients with cancer may have significant adverse consequences, including the suppression of both innate and acquired immune responses. Although studies have examined the possibility that regional anesthesia attenuates the immunosuppressive response of surgery, the effects of morphine and other opioid-related substances on tumor progression remain unknown. Methods This article presents an evidence-based review of the influence of opioids and anesthetic technique on the immune system in the context of cancer recurrence. The review focuses on the field of regional anesthesia and the setting of surgical oncologic procedures. The method for perioperative pain management and the technique of anesthesia chosen for patients in cancer surgery were explored. Results General anesthetics have been indicated to suppress both cell-mediated immunity and humoral immunity. Evidence suggests that intravenous opioids suppress the immune system. However, the mechanisms by which anesthetics and analgesics inhibit the immune system are not understood. Compared with the alternatives, regional analgesia offers reduced blood loss and superior postoperative analgesia. Because of these advantages, the use of regional analgesia has increased in oncologic surgeries. Conclusion Immune responses from all components of the immune system, including both the humoral and cell-mediated components, appear to be suppressed by anesthetics and analgesics. The clinical anesthesiologist should consider these factors in the application of technique, especially in cancer surgery. PMID:24940132

    Unsuccessful anesthesia of the inferior alveolar nerve (IAN) may be due to supplementary innervations of mandibular molars from other branches, namely the cervical plexus (CP). The purpose of this prospective, randomized, double-blind, controlled trial was to determine the effectiveness of an intraoral cervical plexus anesthetic technique (ICPAT) in mandibular molars with symptomatic irreversible pulpitis (SIR) when the IAN and lingual nerve (LN) blocks failed, and to provide a description of the technique. Forty patients diagnosed with SIR received IAN and LN block anesthesia prior to treatment. After clinical signs of anesthesia, patients were subjected to an electrical pulp test (EPT) at 2-min cycles for 10 min post-injection. The anesthesia was considered unsuccessful if there was a positive EPT response ten minutes following profound lip numbness. The experimental group (n = 20) were administered 2% Lidocaine with 1:100,000 epinephrine using the ICPAT. The control group (n = 20) were administered 0.9% sterile saline using the ICPAT. Success was defined as no response on two consecutive readings from an EPT. In the experimental group, 60% of subjects showed successful anesthesia, whereas none of the subjects in the control group had successful anesthesia. A multiple logistic regression analysis showed that the anesthesia success rate using the ICPAT method was significantly higher (P < 0.05) than in the control group, irrespective of molar tooth type. The ICPAT method may be useful as a supplementary anesthetic technique for mandibular molars with SIR in subjects whom the IAN and LN blocks do not provide adequate anesthesia. PMID:25864872

    The congenital myasthenia syndromes form a heterogeneous group of genetic diseases characterized by defective neuromuscular transmission. Although they have muscle fatigability in common with the acquired immune myasthenia syndrome, there are important pathophysiological, diagnostic, management and progression pattern differences between them. We report the management of a 28-yr-old patient with longstanding congenital myasthenia syndromes, who underwent an elective cesarean delivery under spinal anesthesia. Muscle imbalance plus weakness-related scoliosis and chronic respiratory failure complicated her management. Ultrasonography was used to facilitate the spinal anesthetic. Intraoperative noninvasive positive pressure ventilation maintained lung volumes effectively and prevented deterioration in respiratory function. PMID:18806046

    Purpose The red-hair phenotype, which is often produced by mutations in the melanocortin-1 receptor gene, has been associated with an increase in sedative, anesthetic, and analgesic requirements in both animal and human studies. Nevertheless, the clinical implications of this phenomenon in red-haired patients undergoing surgery are currently unknown. Methods In a secondary analysis of a prospective trial of intraoperative awareness, red-haired patients were identified and matched with five control patients, and the relative risk for intraoperative awareness was determined. Overall anesthetic management between groups was compared using Hotelling’s T2 statistic. Inhaled anesthetic requirements were compared between cohorts by evaluating the relationship between end-tidal anesthetic concentration and the bispectral index with a linear mixed-effects model. Time to recovery was compared using Kaplan-Meier analysis, and differences in postoperative pain and nausea/vomiting were evaluated with Chi square tests. Results A cohort of 319 red-haired patients was matched with 1,595 control patients for a sample size of 1,914. There were no significant differences in the relative risk of intraoperative awareness (relative risk = 1.67; 95% confidence interval 0.34 to 8.22), anesthetic management, recovery times, or postoperative pain between red-haired patients and control patients. The relationship between pharmacokinetically stable volatile anesthetic concentrations and bispectral index values differed significantly between red-haired patients and controls (P < 0.001), but without clinical implications. Conclusion There were no demonstrable differences between red-haired patients and controls in response to anesthetic and analgesic agents or in recovery parameters. These findings suggest that perioperative anesthetic and analgesic management should not be altered based on self-reported red-hair phenotype. PMID:25681040

    The most common cause of difficult intubation in pediatrics is due to congenital anomalies of airway. We report a case of neonate with congenital epulis (CE) who presented with a difficult airway. A 7-day old neonate weighted 3.2 kg with a large mass occupying the oral cavity that was diagnosed as congenital epulis was scheduled for excision biopsy. The mass was large, mobile, and moving in and out with no clear pedicle. An intravenous line was inserted and secured. The airway was then assessed while the patient was awake and an assistant displaced the mass and a laryngoscope was placed to visualize the larynx easily. After preoxygenation, inhalation induction of anesthesia was accomplished using sevoflurane in oxygen. Endotracheal intubation was performed with conventional laryngoscopy. The baby made uneventful recovery after the surgical procedure. In conclusion, epulis presents a real challenge to anesthesiologists. It can be excised either under local or general anesthesia, depending on the size of its pedicle. If done under general anesthesia, assessment of the airway is mandatory for better airway management and safe endotracheal intubation. PMID:25885516

    Cystic hygroma is a congenital benign tumor occurring due to the accumulation of lymph and during its anesthetic management difficulties are known to be encountered. A newborn baby presented with a massive swelling in the front of the neck. It was an antenatally diagnosed case of cystic hygroma with intraoral extension proving to be an anticipated difficult airway. Following inhalational induction, mask ventilation was possible, and the child was successfully intubated. Intra-operative period was uneventful, and the tumor was completely excised. Postoperatively, the child was ventilated for 24 h in view of anticipated airway edema. PMID:26417143

    Sleep apnea patients pose a challenge for surgeons, anesthesiologists, and surgical facilities as there is increased risk for anesthetic and postoperative complications. Precautions before and after surgery minimize these risks. Screening for sleep apnea should be done for all surgical patients. Safe perioperative management requires judicious use of narcotics and sedating medications, reducing upper airway edema, prevention of aspiration and deep vein thrombosis, blood pressure control, use of positive airway pressure, and proper postoperative monitoring. Although the literature lacks specific recommendations, the guidelines presented in this article are based on more than 20 years of experience and supported by peer-reviewed medical literature.

    A limited number of cases of anesthetic management of Rubinstein-Taybi Syndrome (RTS) have been reported since this syndrome was first diagnosed in 1963. After some well-publicized complications following anesthesia for patients with RTS, there has been great interest in avoiding all precipitant factors and careful monitoring during intraoperative and postoperative periods. This case series examines the cases of three pediatric patients with RTS who presented to the Children's Hospital of Michigan for different surgeries. We aim in this study to share information about this rare syndrome and to emphasize how this case series allowed us to improve our anesthetic management. In each case, we adjusted our techniques using information from preceding cases to avoid complications in the following encounter. PMID:22435286

    Rubinstein-Taybi syndrome (RTS) is a chromosomopathy associated to molecular mutations or microdeletions of chromosome 16. It has an incidence of 1:125,000-700,000 live births. RTS patients present craniofacial and thoracic anomalies that lead to a probable difficult-to-manage airway and ventilation. They also present mental retardation and comorbidity, such as congenital cardiac defects, pulmonary structural anomalies and recurrent respiratory infections, which increase the risk of aspiration pneumonia. Cardiac arrhythmias have been reported after the use of certain drugs such as succinylcholine and atropine, in a higher incidence than in general population. There is an increased risk of postoperative apnea-hypopnea in these patients. We report the anesthetic management in a RTS patient undergoing emergent thoracic surgery due to oesophageal perforation and mediastinitis. Lung isolation was achieved with a bronchial blocker guided with a fiberoptic bronchoscope and one-lung ventilation was performed successfully. PMID:27062171

    Myasthenia gravis (MG) is a rare disorder involving neuromuscular junction. In conjunction with medical therapy, thymectomy is a known modality of treatment of MG and has shown to increase the probability of remission and overall symptomatic improvement. For minimally invasive thymectomy, video-.assisted thoracoscopic surgery has been the preferred surgical approach till recently. The robotic surgical procedure must necessarily bring new challenges to the anesthesiologists to effectively meet the specific requirements of the technique. At present, there is a paucity of literature regarding the anesthetic concerns of robotic assisted thymectomy, patient in question specifically posed a challenge since different maneuvers and techniques had to be tried to obtain optimum surgical conditions with stable ventilatory and hemodynamic parameters. Concerns of patient positioning and hemodynamic monitoring have also been discussed. PMID:27625494

    2011-03-01

    Brittle cornea syndrome (BCS) is a rare autosomal recessive disease that affects the connective tissue. The syndrome is caused by genetic changes in the 4.7-Mb interval between the D16S3423 and D16S3425 markers on the 16q24 chromosome and mutations in the Zinc-Finger 469 gene (ZNF469). BCS is characterized by thin and fragile cornea that tends to perforate spontaneously or as a result of minor trauma to the eye. In addition, the patient usually suffers from hearing loss, mental retardation, hyperextensibility of skin and joints, as well as varying degrees of scoliosis. This phenotypical expression presents an interesting challenge to anesthetic care. We briefly present the perioperative management of a patient with BCS who underwent three cesarean sections.

    Acute and chronic pain control is a significant clinical challenge that has been largely unmet. Local anesthetics are widely used for the control of post-operative pain and in the therapy of acute and chronic pain. While a variety of approaches are currently used to prolong the duration of action of local anesthetics, an optimal strategy to achieve neural blockage for several hours to days with minimal toxicity has yet to be identified. Several drug delivery systems such as liposomes, microparticles and nanoparticles have been investigated as local anesthetic delivery vehicles to achieve prolonged anesthesia. Recently, injectable responsive hydrogels raise significant interest for the localized delivery of anesthetic molecules. This paper discusses the potential of injectable hydrogels to prolong the action of local anesthetics. PMID:25690085

    Mulvihill-Smith syndrome is a rare disease that belongs to progeroid syndromes. This syndrome is characterized by a senile face with an underdeveloped lower half, short stature, microcephaly, multiple pigmented nevi, immunodeficiency, hearing loss, and high-pitched voice. We report anesthetic management of a 27-year-old woman, 138 cm and 27 kg, with this syndrome, who underwent removal of mandibular cyst, partial resection of tongue and keratoplasty. Anesthesia was induced with fentanyl, propofol and vecuronium. There was difficulty in maintaining adequate ventilation with a face mask for children, and we used a mask for infants. Her Cormack grade was rated 3 but her trachea could be intubated assisted by BURP procedure. Anesthesia was maintained with sevoflurane, nitrous oxide and oxygen supplemented with fentanyl. The changes of blood pressure during anesthesia were extraordinary, suggesting the presence of advanced arteriosclerosis. The postoperative course was uneventful, with stable hemodynamics, and the patient was discharged from the hospital on 9th postoperative day. Anesthesia for Mulvihill-Smith syndrome should be performed with caution for the potential risk of difficult airway and unstable hemodynamics. PMID:17633848

Spirometers continuously measure volume, airway pressure, and flow while calculating and continuously displaying respiratory system compliance and resistance in the form of loops. The aim of this case series is to show how observation of spirometric loops, similar to electrocardiogram or CO2 curve monitoring, can improve safety of anesthetic management in small animals. Spirometric monitoring cases described in this case series are based on use of the anaesthesia monitor Capnomac Ultima with a side stream spirometry sensor. The cases illustrate how recognition and understanding of spirometric loops allows for easy diagnosis of iatrogenic pneumothorax, incorrect ventilator settings, leaks in the system, kinked or partially obstructed endotracheal tube, and spontaneous breathing interfering with intermittent positive-pressure ventilation. The case series demonstrates the potential of spirometry to improve the quality and safety of anesthetic management, and, hence, its use can be recommended during intermittent positive-pressure ventilation and procedures in which interference with ventilation can be expected.

    Ex utero intrapartum treatment (EXIT) procedures are therapeutic interventions for fetuses with life-threatening airway abnormalities and/or other prenatally diagnosed congenital malformations requiring immediate neonatal extracorporeal membrane oxygenation support. Although certain anesthetic goals are common among EXIT procedures, many different approaches to their management have been described in the literature. Herein, we present a novel anesthetic approach to an EXIT procedure for fetal micrognathia and retrognathia. We also review the indications and anesthetic considerations for these procedures and highlight the need for multidisciplinary collaboration to optimize clinical outcomes. PMID:27185679

    New developments--in the form of emerging clinical settings for regional anesthesia as well as problems arising with the concomitant use of regional techniques and hemostasis-altering drugs--require the ongoing revision of safety guidelines. The annual meeting of ESRA held in Spain in 2003 saw the discussion and clarification of a variety of issues of current concern, including conclusions reached on the estimated risk of spinal hematoma when published safety guidelines are followed or not, precautions to take in epidural anesthesia during cardiac surgery, guidelines for using fondaparinux for thromboprophylaxis, the circumstances under which neuroaxial techniques can be used safely in patients under the effects of platelet aggregation inhibitors such as thienopyridine, and the application of epidural anesthesia in parturients with eclampsia who have received platelet aggregation inhibitors. Conclusions drawn at the meeting enrich and clarify certain important safety issues related to local and regional anesthesia in patients receiving antiplatelet drugs and/or anticoagulants.

    Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by the deposition of lipoproteinaceous materials in the bronchoalveolar tree. Whole lung lavage was introduced in the 1960s and remains a treatment of choice for PAP. The main anesthetic challenge of whole lung lavage is maintaining adequate oxygenation during the procedure. We describe 2 interesting patients with PAP, the anesthetic challenges faced during the lung lavage, and discuss the management strategies adopted in each case. PMID:26795910

    Donor sites from split-thickness skin grafts (STSG) impose significant pain on patients in the early postoperative period. We report the use of continuous local anesthetic infusion as a method for the management of postoperative STSG donor site pain. Patients undergoing single or dual, adjacent STSG harvest from the thigh (eight patients) or back (one patient) were included in this study. Immediately after STSG harvest, subcutaneous catheters were placed for continuous infusion of local anesthetic. Daily donor site-specific pain severity scores were prospectively recorded in nine patients receiving local anesthetic infusion. Patient characteristics, technical aspects, and postoperative complications were identified in the study. The thigh was the anatomic location chosen for most donor sites. A single catheter was placed for donor sites limited to 4 inches in width or less. A dual catheter system was used for those wider than 4 inches. An elastomeric pump delivered continuously a total of 4 ml/hr of a solution of 0.5% bupivacaine. The average anesthetic infusion duration was 3.1 days. A substantial decrease in worst, least, and average donor site pain scores was found from the first 24 hours to the second postoperative day in our patients, a treatment trend that continued through postoperative day 3. One patient developed minor anesthetic leakage from the catheter insertion site; and in three cases, accidental dislodgement of the catheters occurred. There were no cases of donor site secondary infection. All donor sites were completely epithelialized at 1-month follow-up. Continuous local anesthetic infusion is technically feasible and may represent an option for postoperative donor site pain control after STSG harvesting. Relative cost-benefit of the technique remains to be determined. PMID:23271060

    Intravenous propofol anesthesia is better than inhalational anesthesia for otologic surgery, but cost and intraoperative movement make this technique prohibitive. This study compares a propofol sandwich anesthetic with a total propofol or inhalational anesthetic for otologic surgery to determine which produces the best perioperative conditions and least expense. One hundred twenty patients undergoing ear surgery were randomly chosen to receive an anesthetic with either isoflurane (INHAL), total propofol (TPROP), or propofol used in conjunction with isoflurane (PSAND). Postoperative wakeup and the incidence and severity of nausea, vomiting, and pain were compared among groups. Antiemetic administration and discharge times from recovery and the hospital were also compared. The groups were similar, but anesthesia times were longer in the INHAL group. Emergence from anesthesia after PSAND or TPROP was more rapid than after INHAL. Recovery during the next 24 hours was associated with less nausea and vomiting with PSAND than with INHAL. The cost of the PSAND anesthetic was similar to that of INHAL, and both were less than TPROP. PSAND anesthesia may be similar to TPROP and better than INHAL for otologic procedures. PSAND was less expensive than TPROP and produced a similar recovery profile and antiemetic effect in the 24-hour period after surgery. PMID:10064647

    2014-01-01

    Now-a-days truncus arteriosus has been known as “common arterial trunk” (CAT) and is an uncommon congenital cardiac defect presenting in about 1-3% congenital heart disease. Environmental and genetic factors effects on incidence of CAT and other conotruncal anomalies. The majority patients with CAT and 22q11 deletion have other anomalies such as hypoplasia or aplasia of the thymus or parathyroid glands and immune deficits (T-cell deficiency), calcium metabolism disorder (hypocalcemia), palatal defects, learning and speech disorder, craniofacial anomalies, and neuropsychological abnormalities. CAT without surgical treatment frequently involves early severe pulmonary arterial hypertension (PAH) or early death from heart failure and associated conditions. Therefore, without corrective surgical repair, most CAT patients die in the initial years of life. In numerous centers early surgical repair associated with superior than 80% long-standing survival. Anesthesiologist must be performs comprehensive preoperative evaluation of infants or neonates with this disorder. In CAT patient exactly hemodynamic monitoring and suitable techniques to regulate pulmonary vascular resistance and systemic vascular resistance and cardiac function are more important than the select of a special anesthetic drug. Therefore, anesthetic drugs should be carefully administrated and titrate and under monitoring. Management of CAT after surgical repair depends on the adequacy of treatment, cardiac function, level of PAH, and degree of bleeding. Inotropic support is frequently necessary after the cardiac ischemia associated to the surgical repair. Pulmonary vasodilator drugs were used to PAH treatment. PMID:25097611

    Background: Peroral endoscopic myotomy (POEM) is a novel method of treating achalasia of the esophagus. Very little data are available to guide the anesthesia providers caring for these patients. The anesthetic challenges are primarily related to the risk of pulmonary aspiration. There is also a potential risk of pneumomediastinum, pneumoperitoneum, subcutaneous, or submucosal emphysema, as a result of carbon dioxide tracking into the soft tissues surrounding the esophagus and lower esophageal sphincter. Methods: In this retrospective study, electronic charts of 24 patients who underwent POEM over 18 months were reviewed. Demographic data, fasting status, relevant aspiration risks, anesthetic technique, and postoperative care measures were extracted. Results: Fasting times for both solids and liquids were variable. None of the patients underwent preprocedural esophageal emptying. Standard induction and intubation were performed in 16, rapid sequence induction (RSI) with cricoid pressure in seven, and modified rapid sequence without application of cricoid pressure in one of the patients. One of the patients aspirated at induction, and the procedure was aborted. However, the procedure was performed successfully after a few weeks, this time a RSI with cricoid pressure was chosen. Conclusion: As there are no guidelines for the perioperative management of patients presenting for POEM presently, certain recommendations can be made. Preprocedural esophageal emptying should be considered in patients considered as high-risk, although cultural factors might preclude such an approach. Induction and intubation in a semi-reclining position might be useful. Although debatable, use of RSI with cricoid pressure should be strongly considered. PMID:27212764

    Despite evidence in the literature, continuing wide variation exists in anesthetic technique for primary joint arthroplasties. Recent evidence suggests that neuraxial anesthesia has advantages over general anesthesia in terms of mortality, major morbidity and healthcare utilization. Yet, despite the proposed benefits, utilization of these two techniques varies greatly across geographical locations, with general anesthesia being most common for total hip arthroplasty (THA) and total knee arthroplasty (TKA) in parts of the world. We uncover some factors that promote or hinder the use of neuraxial anesthesia in THA and TKA. Healthcare professionals should be familiarized with the evidence for neuraxial anesthesia, and unbiased educational material should be developed for patients regarding anesthetic options for THA and TKA in order to promote best practice.

    Background: Complete obstruction of the abdominal aorta at the renal artery level is a difficult surgical problem. Aortic clamping and declamping can lead to profound haemodynamic changes, myocardial infarction, ventricular failure or even death may result. These complications are important challenges in anesthetic management of these patients. Methods: Between August, 2010 and April, 2012, descending thoracic aorta to femoral artery bypass grafting was used to revascularize lower limbs in 11 patients in our institute. The anesthetic management of these patients is described here. Epidural catheter placement was done in T 5-6 or T 6-7 space for post operative pain relief. Induction was done by, Inj. Glycopyrolate 0.2 mg, Inj. Fentanyl 5 μg/kg., Inj. Pentothal sodium 5 mg/kg, Inj. Rocuronium 0.9 mg/kg, IPPV done. Left sided double lumen tube was inserted, Maintenance of Anesthesia was done by O2 + N2 O (30:70). Increments of Vecuronium and Fentanyl were given Monitoring of Heart rate, arterial pressure, central venous pressure were continuously displayed. The available pharmacological agents were used when there is deviation of more than 15% from base line. Results: In our study, inspite of measures taken to control rise in blood pressure during aortic cross clamping, a rise of 90 mm of Hg in one patient and 60-80 mm of Hg in four patients was observed, which was managed by sodium nitropruside infusion. At the end of surgery seven patients were extubated on the operation table. In remaining four patients DLT was replaced by single lumen endotracheal tube and were shifted to ICU on IPPV. They weaned off gradually in 3-5 hours. In our series blood loss was 400 ml to 1000 ml. There was no mortality in the first 24 hours. Postoperative bleeding was reported in one case which was re-explored and stood well. Conclusion: The anesthetic technique during aortic surgery is directed at minimizing the hemodynamic effects of cross clamping in order to maintain the myocardial

    Anesthetic management of superior vena cava syndrome carries a possible risk of life-threatening complications such as cardiovascular collapse and complete airway obstruction during anesthesia. Superior vena cava syndrome results from the enlargement of a mediastinal mass and consequent compression of mediastinal structures resulting in impaired blood flow from superior vena cava to the right atrium and venous congestion of face and upper extremity. We report the successful anesthetic management of a 42-year-old man with superior vena cava syndrome posted for cervical lymph node biopsy. PMID:22557753

    Anesthetic management of pheochromocytoma is complicated and challenging. Extra-adrenal pheochromocytoma is a rare neuroendocrine tumor that produces, stores and secretes catecholamines. The main-stay in the management of pheochromocytoma surgeries is Preoperative preparation which has improved perioperative outcome. Modern anesthetic drugs with advanced monitoring have contributed to intraoperative stability. Resection of the tumor results in acute withdrawal of catecholamines, which may lead to severe hypotension. In perioperative period, adequate hydration should be maintained. Beta-blockers, nitroglycerine, sodium nitroprusside and phenylephrine are required to avoid hemodynamic fluctuations and should be used appropriately. PMID:26957701

    Background: Neurologic and Adaptive Capacity Scoring (NACS) has been introduced as a screening test for diagnosis of central nervous system depression due to intrapartum drugs on the neonate. This test can show neurological and behavioral changes even in the presence of a normal Apgar score. NACS has 20 indicators, each indicator allocating to itself the score zero, one or two. The aim of this study was to compare the effects of different anesthetic techniques on the NACS values. Materials and Methods: This study was performed as a randomized, single-blind clinical trial on 75 infants born with elective cesarean in Shahid Beheshti Hospital, Isfahan. Simple Sampling method was carried out and the information was gathered by questionnaires. Anesthetic techniques included general, spinal or epidural anesthesia. NACS score was assessed at 15th min, 2 and 24 h after birth and then the anesthesia technique was recorded in the questionnaire. NACS score 35 or above was considered normal and 34 or less was abnormal. Results: In the present study, no significant correlation was found between the anesthesia techniques and NACS score. The mean NACS at 15 min after birthin the general, spinal and epidural groups were 33.5 ± 2.2, 33.0 ± 4.4 and 33.7 ± 1.6 respectively (P = 0.703). Conclusion: All three anesthetic techniques have identical effects on neurological and compatibility capacity of neonates born with elective cesarean; so, this could necessarily be a base to recommend the three methods equally.

    Background: The efficacy of epidural and facet joint injections has been assessed utilizing multiple solutions including saline, local anesthetic, steroids, and others. The responses to these various solutions have been variable and have not been systematically assessed with long-term follow-ups. Methods: Randomized trials utilizing a true active control design were included. The primary outcome measure was pain relief and the secondary outcome measure was functional improvement. The quality of each individual article was assessed by Cochrane review criteria, as well as the criteria developed by the American Society of Interventional Pain Physicians (ASIPP) for assessing interventional techniques. An evidence analysis was conducted based on the qualitative level of evidence (Level I to IV). Results: A total of 31 trials met the inclusion criteria. There was Level I evidence that local anesthetic with steroids was effective in managing chronic spinal pain based on multiple high-quality randomized controlled trials. The evidence also showed that local anesthetic with steroids and local anesthetic alone were equally effective except in disc herniation, where the superiority of local anesthetic with steroids was demonstrated over local anesthetic alone. Conclusion: This systematic review showed equal efficacy for local anesthetic with steroids and local anesthetic alone in multiple spinal conditions except for disc herniation where the superiority of local anesthetic with steroids was seen over local anesthetic alone.

    Before the 19(th) century, ether and nitrous oxide were synthesized. However, they were just used as a kind of enjoyable things at night gatherings for their hypnotic and analgesic effect. In the 19(th) century, ether and nitrous oxide came into use in clinical anesthesia. Thereafter, more and more chemical narcotics were synthesized and applied to clinical anesthesia. In 1872, chloroform was injected into man's vein for anesthesia. In the 20(th) century, along with many kinds of barbiturates being synthesized, intravenous anesthesia got much development and application. At the same time, related techniques of anesthesia also improved. In the early 19(th) century, open inhalation anesthesia was often used. In 1900, there came a new anesthesia method by blowing into the windpipe through the cut of throat. Later on, the technique of endotracheal anesthesia and artificial respiration anesthesia (1908), the anesthetic instrument of endotracheal intubation and laryngeal mask and laryngoscope were invented. In the mid 19(th) century, the appearance of injection syringe and cocaine made local anesthesia possible. In 1880, local anesthesia also became successful. Thereafter, a variety of local anesthetic drugs were synthesized and applied, companying with various techniques of local anesthesia such as subarachnoid anesthesia (1900), sacral anesthesia (1901), epidural block (1903), plexus block (1902) and so on. In order to control the depth of anesthesia and respiration effectively, people attempted a lot so that anesthesia machine (1910), improved endotracheal anesthesia (1921), cryogenic technique (1902), controlled hypotension (1940s) and artificial hibernation (1950) came into being.

    Increasing numbers of adult patients with complex congenital heart conditions are presenting for noncardiac surgery later in life. These disorders can present challenges for surgical and anesthesia providers. Specifically, single ventricle lesions offer anatomic and physiologic concerns during the perioperative period. Single ventricle physiology represents a delicate balance between systemic and pulmonary blood flow. Any alterations in blood flow through these systems can produce undesirable hemodynamic changes, especially during the perioperative period. We present a case of an adult patient with a single left ventricle who presented for laparoscopic total colectomy due to inflammatory bowel disease. His abnormal anatomy coupled with the hemodynamic disruptions caused by laparoscopy presented significant anesthetic challenges. We highlight the anesthetic concerns of single ventricle physiology, specifically pertaining to laparoscopic surgery. We provide recommendations for safely managing these patients perioperatively. With detailed preoperative evaluation and close hemodynamic monitoring during the perioperative period, these patients can experience successful surgical and anesthetic outcomes. PMID:25849703

    Data from the records of 142 patients for carotid endarterectomy at Chugoku Rosai General Hospital between 1983 and 1995, were evaluated concerning perioperative risk factors and anesthetic management. As a preoperative anesthetic risk, the incidence of hypertension was the commonest (76%), and there was a significant incidence of ischemic heart disease (18%). Fentanyl and isoflurane have been used for anesthesia recently and the patients were closely observed and cared in the intensive care unit postoperatively. In order to prevent cerebral ischemia during the occlusion of the internal carotid artery, we measured somatosensory evoked potential as well as jugular venous oxygen saturation, and used near infrared spectophotometry. As a result, postoperative mortality and morbidity were 0% and 2%, respectively. The candidates for CEA have potentially high perioperative risks, and it is important to evaluate the coexisting diseases and to select proper anesthetic technic and monitors. PMID:9185470

    Anesthesiologists are acutely aware of the fact that, although a given surgical procedure may be relatively simple, the required anesthetic care is, in certain cases, extremely complex. This principle is particularly evident when one ponders the difficulties involved in providing even basic anesthetic care in microgravity. In this issue some of these difficulties through the evaluation of airway management techniques during water immersion are confronted, a simulation of the gravito-inertial conditions of space flight. As prelude for this paper, I would like to outline some of the challenges to be overcome before surgical, anesthetic, and critical care can be delivered beyond our home planet.

    Resistant hypertension is a prevalent dilemma. Despite all available antihypertensive medications and multiple strategies such as healthier diets and exercise programs, many patients are still unable to maintain or reach a therapeutic goal for systolic blood pressure. Because of this major health concern, CVRx, Inc has developed a treatment involving baroreflex activation therapy (Rheos Baroreflex Hypertension Therapy System) to treat patients with uncontrolled high blood pressure. The surgical implantation of this system is similar to a carotid endarterectomy procedure; however, the anesthetic management for this procedure is unique and challenging. This case report describes a 45-year-old African American woman with a history of hypertension who was receiving multiple antihypertensive medications and, thus, was a qualified candidate for implantation of this device. The goal of anesthetic management during implantation of this hypertension therapy system is to preserve the carotid sinus baroreceptor sensitivity by avoiding administering anesthetic agents that inhibit the baroreceptor reflex during electrode placement and the testing period. Because of the restriction of some of the anesthetic agents that an anesthesia provider can use, this procedure poses major challenges to the anesthesia provider in planning for anesthesia care and managing risks to the patient.

    Although life expectancy of the patients with Eisenmenger syndrome (ES) is currently reported to be lower than 40 years, life span of the patients with ES may be extended because of development of medical care. According to recently reported middle-aged patients with ES undergoing non-cardiac surgeries, per-operative mortality and morbidity of the patients with ES undergoing non-cardiac surgeries may be lower than previously thought, and even elderly patients may be able to undergo major surgeries such as laparotomies for cancers. We described the anesthetic management of a 69-year-old patient with ES who had undergone abdominoperineal resection. In the anesthetic management it is important to maintain adequate blood volumne and systemic vascular resistance and this avoids increases of right-to-left shunt. Perioperative monitoring of pulmonary arterial pressure was useful for hemodynamic management. Good pain control and management of body temperature were also needed for a perioperative course with no adverse events. The appropriate anesthetic management of the 69-year-old patient with ES for abdominoperineal resection resulted in the successful perioperative course. PMID:27483658

Nasopharyngeal laryngoscopy revealed large, mobile, bilateral vocal cord polyps that demonstrated dynamic occlusion of the glottis. We describe the airway and anesthetic management of this patient with a topicalized C-MAC video laryngoscopic intubation using a 4.5 mm Xomed Laser Shield II endotracheal tube. We examine the challenges of anesthetic management unique to the combined circumstances of a ball-valve lesion and the need for a narrow-bore laser compatible endotracheal tube. PMID:26090238

    Background: Head injury presents a major worldwide social, economic, and health problem. Hyperglycemia is a significant indicator of the severity of injury and predictor of outcome, which can easily be prevented. There has been a long-standing controversy regarding the use of inhalational or intravenous (i.v.) anesthetic agents for surgery of head injury cases and impact of these agents on blood sugar level. Aims and Objectives: The aim of this study is to find out anesthetic drugs and technique having minimal or no effect on the blood sugar, and Glasgow Coma Scale (GCS) of patients with a head injury by comparing two types of anesthetic techniques in surgery of head injury patients. Materials and Methods: This was a prospective, randomized, and comparative study, conducted on 60 adult head injury patients. The patients were divided into two groups of 30 each. Group I patients received induction with sevoflurane and then had O2 + air + sevoflurane for maintenance with controlled ventilation. Group II patients received induction with i.v. propofol and then had O2 + air + propofol for maintenance with controlled ventilation. Injection fentanyl was used in both the groups at the time of induction and in intermittent boluses in maintenance. In observation, blood sugar level and mean arterial pressure were assessed at different time periods perioperatively in both groups while GCS was analyzed pre- and post-operatively. Statistical Analysis: Statistical analysis was performed by Microsoft Excel 2010 using t-test for comparison between the two groups and Z-test for comparison of proportions. Results and Conclusion: Blood sugar level was found significantly higher in patients of sevoflurane group at 30 min after induction, at the end of surgery, and 1 h after the end of anesthesia than propofol group patients. This increase of blood sugar level did not have any significant alteration in the GCS profile of the patients in sevoflurane group as compared to propofol group

    The anesthetic management for open fetal surgery has been described, but many therapeutic tenets have not been supported with data. We present data on the anesthetic management and outcomes of 65 patients undergoing ex utero intrapartum therapy procedures at the Children's Hospital of Philadelphia between 1998 and 2011. Patients were identified, and medical records were retrospectively reviewed. Maternal general anesthesia combined with postoperative epidural analgesia was commonly used. High levels of volatile anesthetic were used for uterine relaxation. Case characteristics such as fetal procedure, operative time, blood loss, transfusion requirements, vasopressor use, and fetal resuscitative measures are described. PMID:27258076

    The stiff-person syndrome (SPS) is a rare autoimmune neurologic disorder that affects the gamma-aminobutyric acid (GABA) mediated inhibitory network in the central nervous system with anti-glutamic acid decarboxylase (GAD) antibodies. SPS is characterized by muscle rigidity and painful episodic spasms in axial and lower limb muscles. This case report describes successful peri-operative management of a 61-year-old female (height, 158 cm; weight, 60 kg, ASA-PS 2) with her right upper arm fracture who was scheduled for open reduction and internal fixation. This patient had bulbar paralysis, dysphagia and muscle rigidity associated with a high titer of anti-GAD auto antibodies (2,800 U x ml(-1)). She was diagnosed as SPS and has been treated with predonisolone (30 mg x day(-1)) and diazepam (20 mg x day(-1)) for 1 year. Predonisolone (15 mg) and diazepam (30 mg) was given orally before induction of general anesthesia with propofol, remifentanil and rocuronium bromide. Posture change from supine to beach-chair position led to sudden drop in blood pressure to 38/25 mmHg, which recovered promptly by injecting intravenous ephedrine hydrochloride (28 mg) and hydrocortisone (100 mg). Postanesthetic course was uneventful without postoperative neurologic abnormalities. PMID:27017773

    Stiff person syndrome is a rare neurologic disorder with an estimated incidence of 1:1000000. The underlying pathophysiology is truncal and proximal limb muscle stiffness resulting from continuous co-contracture of agonist and antagonist muscle groups concomitant with superimposed episodic muscle spasms. Loss of gamma-aminobutyric acid-mediated inhibition creates chronic excitation manifested by tonic agonist-antagonist muscle contraction. To date, only three case reports referred indirectly to the anesthetic management of parturients with Stiff person syndrome. The authors describe their management of a parturient with Stiff person syndrome who underwent urgent cesarean delivery under epidural anesthesia. PMID:27378710

    Patients with mediastinal masses present unique challenge to anesthesiologists. Patients with anterior mediastinal masses have well documented cases of respiratory or cardiovascular collapse during anesthesia and in postoperative period. Masses in the posterior mediastinum have been traditionally regarded to carry a significantly lower risk of anesthesia related complications but cases of near fatal cardiorespiratory complications have been reported. We describe anesthetic management of a patient with posterior mediastinal mass compressing the trachea and the left main bronchus presented for left thoracotomy and tumor excision. The patient experienced pain and cough, and exhibited positional dyspnea. Airway was successfully secured with awake nasotracheal intubation and placement of single lumen endobronchial tube.

    Introduction: Induction of general anesthesia in patients with superior vena cava (SVC) syndrome may cause airway obstruction and cardiovascular collapse. Case Presentation: Herein, we introduced a patient with the diagnosis of dissecting aneurysm of the ascending aorta who was candidate for emergency surgery. He also had symptoms of SVC syndrome. To maintain airway patency during anesthetic management, we decided to perform femoro-femoral cardiopulmonary bypass followed by general anesthesia and tracheal intubation. Conclusions: Femoro-femoral bypass prior to initiation of sternotomy is a safe and easy method in patients with aortic dissection and SVC syndrome in whom earlier endotracheal intubation may not be feasible.

    Impetigo herpetiformis (IH), or generalized pustular psoriasis of pregnancy, is an exceedingly rare, generalized pustular skin eruption occurring during pregnancy associated with hypovolemia, sepsis, hypocalcemia, and airway edema. Fetal outcomes are generally poor, and parturients with IH may present with emergent indications for cesarean delivery due to placental insufficiency. We present a case of IH in a 19-year-old G1P0 who underwent successful general anesthesia for cesarean delivery. Her case highlights the anesthetic implications for patients afflicted with this rare disease, including perioperative pain management, airway concerns, considerations for neuraxial anesthesia, and monitoring challenges.

    Von Gierke's disease, a form of glycogen storage disturbance, is a rare metabolic disorder with important implications for anesthesiologists. It is caused by the lack of the glucose-6-phosphatase, which is necessary for the liver to convert glycogen to glucose. To avoid severe hypoglycemia, it is crucial to keep oral feeding at intervals 2-3 hr for maintaining a normal blood sugar level. The metabolic derangements of von Gierke's disease may result in serious complications in patients undergoing surgery and anesthesia. We report the anesthetic managements of a patient with von Gierke's disease in two operations with different encounters. PMID:16623410

    Glutaric aciduria type I (GA-1) is an inborn error of metabolism caused by a deficiency of glutaryl-CoA dehydrogenase. It presents early in life, usually after an episode of fever, dehydration, infection or fasting, and results in metabolic decompensation and neurologic damage. We report the perioperative management of a 5-year-old boy admitted to the hospital for surgery because of neurogenic hip dislocation. Here we present the preoperative preparation, which focused on appropriate fluid administration and therapy intensification, as well as the safe anesthetic management with inhalation anesthesia and remifentanil, taking into consideration the mitochondrial basis of the disease. Furthermore, the role of postoperative care is emphasized in relation to stress response prophylaxis and the avoidance of complications related to the disorder. PMID:21221659

    In order to optimize anesthetic management and avoid adverse maternal and fetal outcomes, a clear understanding of the changes in cardiovascular physiology that occur during pregnancy is paramount. The effects of normal gestation on the cardiovascular system are particularly significant in a parturient with cardiac valvular pathology. We present a case of a 27-year-old G2P0 at 37 weeks with a past medical history of diabetes, macrosomia, congenital bicuspid aortic valve with severe stenosis (valve area 0.7 cm2) who was scheduled for elective C-section. A multidisciplinary discussion involving cardiologists, cardiac surgeons, obstetric surgeons, neonatal intensivists, perfusion staff, anesthesiologists, and nursing staff was held to formulate a plan for the perioperative management of this parturient. Also, contingency plans were formulated and discussed with the care providers, in the event of acute decompensation of the mother and baby and possible need for emergency aortic valvuloplasty and/or aortic valve replacement.

    Congenital eventration of the diaphragm is a rare disorder, the perioperative management of which is challenging. The introduction of thoracoscopic repair of these defects has considerably reduced the perioperative morbidity and mortality in these patients. In spite of the advantages of thoracoscopy which include smaller chest incisions, reduced postoperative pain, and more rapid postoperative recovery compared with thoracotomy, it is still inherent with complications unique to it. A clear understanding of the pathophysiologic changes, potential complications and institution of appropriate monitoring and good planning is essential for the safe conduct of thoracoscopic procedures in neonates. We describe the anesthetic management of staged thoracoscopic repair of bilateral congenital eventration of the diaphragm in a neonate. PMID:26957704

    Two indirect blood pressure measurement techniques, Doppler (DOP) sphygmomanometry and oscillometry, applied at the ventral coccygeal artery were compared with simultaneous direct blood pressure measurements at the dorsal pedal artery in 10 anesthetized, captive cheetahs (Acinonyx jubatus). The DOP method was moderately accurate, with relatively little bias (mean difference 3.8 mmHg) and 88.6% of the DOP systolic arterial pressure measurements being within 10 mmHg of the direct systolic arterial measurement. With the oscillometric (OM) method, 89.2% of the mean arterial pressure measurements were within 10 mmHg of the direct measurement and had the least bias (mean difference 2.3 mmHg), 80.7% of the systolic measurements were within 10 mmHg of the direct measurement and had the second least bias (mean difference 2.3 mmHg), and 59% of the diastolic measurements were within 10 mmHg of the direct measurement and had significant bias (mean difference 7.3 mmHg). However, DOP showed relatively poor precision (SD 11.2 mmHg) compared with OM systolic (SD 8.0 mmHg), diastolic (SD 8.6 mmHg), and mean (SD 5.7 mmHg). Both techniques showed a linear relationship with the direct technique measurements over a wide range of blood pressures. The DOP method tended to underestimate systolic measurements below 160 mmHg and overestimate systolic measurements above 160 mmHg. The OM method tended to underestimate mean pressures below 160 mm Hg, overestimate mean pressures above 160 mmHg, underestimate systolic pressures below 170 mmHg, overestimate systolic pressures above 170 mmHg, and underestimate diastolic pressures throughout the measured blood pressure range. Indirect blood pressure measurement using the ventral coccygeal artery, particularly when using an OM device for mean and systolic arterial pressure, may be useful in the clinical assessment of cheetahs when monitoring trends over time, but caution should be taken when interpreting individual values.

    Due to high mortality associated with aortic dissection, anesthetic management of patients with Marfan syndrome with severe aortic root dilation is a challenging situation. We describe the anesthetic management of a patient with Marfan syndrome with severe aortic root dilation, who required major surgery like cholecystectomy with partial liver resection under general anesthesia. A 47-year-old female presented to pre-anesthetic clinic for cholecystectomy with partial hepatic resection for gall bladder carcinoma. Clinical features, transthoracic echocardiography and computed tomography of thorax supported a diagnosis of Marfan syndrome with severely dilated aortic root. Aortic dissection in patients with Marfan syndrome and severely dilated aortic root can be precipitated by major hemodynamic changes under anesthesia. Careful hemodynamic monitoring and avoidance of hemodynamic swings can prevent this life-threatening event. PMID:24348301

    Facial locoregional anesthetics (ALR) with nervous blocks are simple and reliable to perform, need little technical resources with a very low iatrogenic risk. These blocks allow anesthesia without deforming wound banks using the same materials as usual local anesthetic procedures. Three principal nervous blocks, in a straight line along the vertical pupil axis, allow managing - even extensive - facial wounds. Few side effects may occur which can be easily prevented. It is a good alternative to local anesthetic for the treatment of extensive and deep areas which is performed with a lower number of injections and a high rate of success. These techniques are easy to learn and practise. These anesthetic techniques allow a nice treatment of different kinds of facial wounds from simple suture to flaps. PMID:19272691

    Malaria is associated with high rates of morbidity and mortality worldwide, particularly in Africa, Southeast Asia and South America. Nonetheless, several cases of malaria have been reported in Western countries involving travelers from endemic areas, though very few involve pregnant women. In this article, we report a case of a young woman born in Sierra Leone who had been living in Italy for two years. She was admitted to our hospital with malaise; worsening of her condition led to Plasmodium falciparum infection diagnosis early during her hospital stay, as well as an urgent cesarean delivery. We briefly discuss the features of malaria in pregnancy, the difficulties associated with early diagnosis, and the possible fetal and maternal implications, and also consider how the disease may affect anesthetic management.

    Carnitine palmitoyltransferase (CPT) makes the fatty acids available through beta-oxidation. Deficiency of CPT causes difficulties of muscle cells to metabolize fatty acid. In affected patients, exercise, fast for a prolonged period, and stress, lead to exhaustion of the store of glucose in the body, and rhabdomyolysis may occur, since muscle can not utilize fatty acid as an alternative energy source. Therefore, anesthetic management of CPT deficiency needs infusion of glucose continuously, avoiding the use of the drugs that cause rhabdomyolysis and suppressing the surgical stress. A 67-year-old man, who had previous history of rhabdmyolysis during the postoperative period, and diagnosed CPT deficiency was scheduled for total gastrectomy. General anesthesia was induced with remifentanil, thiamylal and rocuronium after epidural catheter insertion. During surgery, general anesthesia was maintained with remifentanil, sevoflurane, and blood glucose was monitored frequently, with continuous glucose infusion. No complications occurred during anesthesia and perioperative course was uneventful. PMID:23544345

    Severe pulmonary arterial hypertension is a significant risk factor for anesthetic management in patients undergoing even non-cardiac surgery. A 64-year-old female patient with severe pulmonary arterial hypertension was scheduled to undergo inguinal hernioplasty. Preoperative systolic pulmonary arterial pressure was 115 mmHg. We selected monitored anesthesia care with 0.2-0.5 μg x kg(-1) x hr(-1) dexmedetomidine and ultrasound-guided iliohypogastric block. Thereafter, LiDCOrapid was used to acquire the hemodynamic responses during surgery. Continuous iliohypogastric block produced postoperative pain relief and the supplemental analgesic was not needed. The monitored anesthesia care by dexmedetomidine and ultrasound guided continuous iliohypogastric block would be a safe procedure for patients with severe pulmonary arterial hypertension undergoing non-cardiac surgery. LiDCO rapid could be low invasive and useful as a hemodaynamic monitor in such a case. PMID:27319099

    Central core disease (CCD) is a dominantly inherited congenital myopathy. CCD is also associated with muscular and skeletal abnormalities such as abnormal curvature of the spine (scoliosis), hip dislocation, and joint deformities. CCD and malignant hyperthermia (MH) are both associated with mutations in the ryanodine receptor on chromosome 19q13.1. An 11-year-old boy with CCD complicated with severe scoliosis was scheduled for spinal fusion surgery under general anesthesia. Furthermore, he had trismus caused by temporomandibular contracture. He was considered as MH susceptible. Anesthesia was managed with remifentanil and propofol without using muscle relaxtants and volatile anesthetics. We could intubate the trachea with Airtraq laryngoscope without any complications. The perioperative course was uneventful. PMID:27483668

    Vallecular cyst is uncommon but well-recognized cause of upper airway obstruction in newborn and infants. We hereby present anesthetic management of a case of vallecular cyst in an infant posted for excision and marsupialization. A 4-month-old female infant weighing 3.5 kg presented with inspiratory stridor progressively worsening over 2 months. Anesthesia plan was to carry out inhalational induction maintaining spontaneous respiration and keeping tracheostomy as standby option. In this case, laryngoscopy was challenging due to the size and extent of the cyst thus necessitating gentle laryngoscopy to prevent cyst rupture and pulmonary aspiration. On performing laryngoscopy, epiglottis was not visualized, which made intubation difficult. At the end of surgery, extubation was not carried out as the possibility of laryngomalacia could not be eliminated and also in view of intraoperative airway manipulation. The patient was electively ventilated postoperatively and extubated on the 2nd postoperative day. PMID:27375399

    Nowadays, even hazardous cardiac surgery can be performed on patients with autoimmune diseases like myasthenia gravis. It requires a sensitive perioperative anesthetic approach especially in relation to nondepolarizing muscle relaxant administration. Myasthenic patients produce antibodies against the end-plate acetylcholine receptors causing muscle weakness and sensitivity to nondepolarizing muscle relaxants that could lead to respiratory failure. Perioperative nurse care is critical for uncomplicated course of treatment; therefore, apprehension of surgical procedure should be helpful on an everyday basis. We describe successful management without any pulmonary complications of two patients with myasthenia gravis undergoing coronary artery bypass grafting. In addition, antiacetylcholine receptor antibodies concentrations were evaluated during treatment time. In conclusion, we have found that reduced titrated doses of cisatracurium may be safely used in patients with myasthenia gravis undergoing cardiac surgery without anesthesia and respiratory-related complications.

    We describe anesthetic management of a pregnant woman (weight 42 kg, height 147 cm) with ileus, requiring emergency cesarean section and ileus operation. Cesarean section was performed under spinal anesthesia and epidural anesthesia, and ileus operation was performed under total intravenous general anesthesia. During ileus operation, the blood pressure decreased to 60/30 mmHg and the heart rate increased to 140 beats x min, indicating the intestinal traction syndrome. Repeated injections of phenylephrine 0.1 mg and albumin preparation 5% 1,500 ml were required to restore blood pressure. After the operation, the patient's trachea was extubated. The last level of the spinal anesthesia was T6. PMID:27188113

    As Japan's population ages, the number of cases of emergency abdominal surgery at advanced ages is increasing. A 105-year-old man weighing 37 kg combined with aortic stenosis and regurgitation was scheduled for emergency surgery for incarcerated inguinofemoral hernia. General anesthesia was induced with short-acting analgesics and sedatives. The patient was extubated uneventfully in the operating room and discharged without any major complications. Anesthetic management of elderly patients requires appropriate preoperative evaluation of complicating diseases, degree of consciousness, and nutritional condition. For those aged 100 years and older in particular, their quality of life should be considered. Close and cooperative communication between surgeons and anesthesiologists are also an important aspect in treating these charged without any major complications. PMID:27017779

    Vallecular cyst is uncommon but well-recognized cause of upper airway obstruction in newborn and infants. We hereby present anesthetic management of a case of vallecular cyst in an infant posted for excision and marsupialization. A 4-month-old female infant weighing 3.5 kg presented with inspiratory stridor progressively worsening over 2 months. Anesthesia plan was to carry out inhalational induction maintaining spontaneous respiration and keeping tracheostomy as standby option. In this case, laryngoscopy was challenging due to the size and extent of the cyst thus necessitating gentle laryngoscopy to prevent cyst rupture and pulmonary aspiration. On performing laryngoscopy, epiglottis was not visualized, which made intubation difficult. At the end of surgery, extubation was not carried out as the possibility of laryngomalacia could not be eliminated and also in view of intraoperative airway manipulation. The patient was electively ventilated postoperatively and extubated on the 2(nd) postoperative day. PMID:27375399

    We report successful anesthetic management of a patient with pheochromocytoma using high-dose landiolol hydrochloride. A 55-year-old man was scheduled to undergo resection of giant pheochromocytoma. Epidural anesthesia was not performed due to anticoagulant therapy for lower limb thrombus. Tracheal intubation was performed with the Pentax-AWS Airwayscope. Preoperative screening revealed urine adrenaline 2.567.0 microg x day(-1) urine noradrenaline 1,734.0 microg x day(-1), and a tumor diameter of 96 x 60 mm. Catecholamine surge was controlled with 50 microg x kg(-1) x min(-1) continuous infusion of landiolol hydrochloride and IV bolus phentolamine. On tumor resection, although systemic blood pressure increased to 294 mmHg and was unresponsive to repeated phentolamine administration, the heart rate remained at 70-105 beats x min(-1) and there were no significant ST changes.

    Malaria is associated with high rates of morbidity and mortality worldwide, particularly in Africa, Southeast Asia and South America. Nonetheless, several cases of malaria have been reported in Western countries involving travelers from endemic areas, though very few involve pregnant women. In this article, we report a case of a young woman born in Sierra Leone who had been living in Italy for two years. She was admitted to our hospital with malaise; worsening of her condition led to Plasmodium falciparum infection diagnosis early during her hospital stay, as well as an urgent cesarean delivery. We briefly discuss the features of malaria in pregnancy, the difficulties associated with early diagnosis, and the possible fetal and maternal implications, and also consider how the disease may affect anesthetic management.

    Anesthetics and psychoactive drugs could relieve diseases, if used properly. However, they can cause dependency, and their misuse or abuse could adversely affect people's health and social stability. For a long time, the Chinese government has been reinforcing the regulation on anesthetics and psychoactive drugs to ensure their legal and proper usage, and to prevent abuse. The state council issued 'the regulations on the administration of anesthetic drugs and psychotropic drugs' in 2005, based on which a legal system was established for administration of anesthetics and psychoactive drugs with the objectives of ensuring their legitimate medical utilization, and preventing illegal abuse.

    Various clinical trials have assessed how intraoperative anesthetics can affect early recovery, hemodynamics and nociception after supratentorial craniotomy. Whether or not the difference in recovery pattern differs in a meaningful way with anesthetic choice is controversial. This review examines and compares different anesthetics with respect to wake-up time, hemodynamics, respiration, cognitive recovery, pain, nausea and vomiting, and shivering. When comparing inhalational anesthetics to intravenous anesthetics, either regimen produces similar recovery results. Newer shorter acting agents accelerate the process of emergence and extubation. A balanced inhalational/intravenous anesthetic could be desirable for patients with normal intracranial pressure, while total intravenous anesthesia could be beneficial for patients with elevated intracranial pressure. Comparison of inhalational anesthetics shows all appropriate for rapid emergence, decreasing time to extubation, and cognitive recovery. Comparison of opioids demonstrates similar awakening and extubation time if the infusion of longer acting opioids was ended at the appropriate time. Administration of local anesthetics into the skin, and addition of corticosteroids, NSAIDs, COX-2 inhibitors, and PCA therapy postoperatively provided superior analgesia. It is also important to emphasize the possibility of long-term effects of anesthetics on cognitive function. More research is warranted to develop best practices strategies for the future that are evidence-based. PMID:26345202

    Objectives Puhnonary apillary hemorrhage can be induced by diagnostic ultrasonnd (US) during direct pulmonary US scanning in rats. The influence of specific anesthetic tedmiques on this bioeffect was examined. Methods Ketamine plus xylazine has been used previously. In this study, the influence of intraperitoneal injections of ketamine and pentobarbital, inhalational isoflurane, and the supplemental use of xylazine with ketamine and isollurane was tested. A diagnostic US machine with a7.6-MHz linear array was used to image the right lung of anesthetized rats in a warmed water bath at different mechanical index (MI) settings. Pulmonary capillary hemorrhage was assessed by measuring comet tail artifacts in the image and by morphometry of the hemorrhagic areas on excised lungs. Results Pulmonary capillary hemorrhage was greatest for pentobarbital, lower for inhalational isoflurane, and lowest for ketamine anesthesia, with occurrence thresholds at at Mis of about 0.44, 0.8, and 0.8, respectively. Addition of xylazine produced a substantial increaseinhemorrhageanda significant proportion of hemorrhage occurrence for ketamineat an MI of 0.7 (P < .01) and forisofluraneat an MI of 0.52 (P < .01). Conclusions Ketamine plus xylazine and pentobarbital yield lower thresholds than ketamine or isoflurane alone by nearly a factor of 2 in MI. These results suggest that the choice of the anesthetic agent substantially modifies the relative risks of pulmonary capillary hemorrhage from pulmonary US. PMID:25614402

    Tail biopsy in mice is a common procedure in genetically modified mouse colonies. We evaluated the anesthetic and analgesic effects of various agents commonly used to mitigate pain after tail biopsy. We used a hot-water immersion assay to evaluate the analgesic effects of isoflurane, ice-cold ethanol, ethyl chloride, buprenorphine, and 2-point local nerve blocks before studying their effects on mice receiving tail biopsies. Mice treated with ethyl chloride spray, isoflurane and buprenorphine, and 2-point local nerve blocks demonstrated increased tail-flick latency compared with that of untreated mice. When we evaluated the behavior of adult and preweanling mice after tail biopsy, untreated mice demonstrated behavioral changes immediately after tail biopsy that lasted 30 to 60 min before returning to normal. The use of isoflurane, isoflurane and buprenorphine, buprenorphine, 2-point nerve block, or ethyl chloride spray in adult mice did not significantly improve their behavioral response to tail biopsy. Similarly, the use of buprenorphine and ethyl chloride spray in preweanling mice did not improve their behavioral response to tail biopsy compared with that of the untreated group. However, immersion in bupivacaine for 30 s after tail biopsy decreased tail grooming behavior during the first 30 min after tail biopsy. The anesthetic and analgesic regimens tested provide little benefit in adult and preweanling mice. Given that tail biopsy results in pain that lasts 30 to 60 min, investigators should carefully consider the appropriate anesthetic or analgesic regimen to incorporate into tail-biopsy procedures for mice.

    The Hermansky-Pudlak syndrome (HPS) is a rare set of disorders characterized by oculocutaneous albinism, bleeding diathesis, and pulmonary fibrosis, with the latter 2 conditions presenting major challenges in anesthetic management. We report a 53-year-old woman with pulmonary fibrosis secondary to HPS who underwent video-assisted bullectomy to treat recurrent pneumothorax. Preoperative bleeding time and platelet count were within normal limits, but the surgeons had difficulty with continuous oozing from the incision site; the surgical blood loss was 270 mL, which was a relatively large amount for this surgery. Because of her restrictive lung disease, the patient's tidal volume was only 250 mL under pressure-controlled ventilation, with a peak inspiratory pressure of 30 cm H2O and a positive end-expiratory pressure of 5 cm H2O. She also had postoperative respiratory insufficiency, with a partial pressure of arterial CO2 of 112 mm Hg and a pH of 7.08 on arterial blood gas analysis. Then, the patient needed mechanical ventilation for 4 days. In conclusion, patients with HPS require strict respiratory management to support their restrictive pulmonary dysfunction, and, also, we should consider preventive management for hemostasis and adequate analgesia to reduce the patient's work of breathing.

    Midazolam and propofol are widely used for the sedation of patients with serious mental and physical disabilities. However, we often experience difficulty in the management of airway and respiratory depression when using these sedatives. Dexmedetomidine (DEX) is being increasingly used as a sedative because of the lack of associated respiratory depression. Here we report anesthetic management with DEX in two patients with disability undergoing dental treatment To avoid movement during treatment, DEX was infused at the rate recommended in the package insert, with an initial administration at 6 μg x kg(-1) x hr(-1) for 10 min followed by maintenance infusion at 0.7 μg x kg(-1) x hr(-1). Although the infusion rate seemed to be sufficient for the patients, DEX was not effective and administration of additional sedatives was required. Further, respiratory depression, such as airway obstruction and increase in the concentration of end-tidal carbon dioxide, was observed even when DEX was used as the sole agent for inducing sedation. No remarkable change in hemodynamics was observed. Therefore, it is difficult to maintain the sedative state using DEX alone in patients with serious mental and physical disabilities in comparison with patients with no disability. PMID:27188121

    Peroral endoscopic myotomy (POEM) is a newly developed, less invasive treatment for esophageal achalasia that requires general anesthesia under positive pressure ventilation. In this retrospective case series, we describe the anesthetic management of 28 consecutive patients who underwent POEM for esophageal achalasia. Anesthesia was maintained with sevoflurane and remifentanil under positive pressure ventilation through a tracheal tube. Retained contents in the esophagus were evacuated just before anesthesia induction to prevent regurgitation into the trachea. The POEM procedure was performed using an orally inserted flexible fiberscope. Elevation of end-tidal carbon dioxide after initiating esophageal carbon dioxide insufflation was observed in all patients and was treated by minute adjustments to the ventilation volume. Scopolamine butylbromide-induced tachycardia in one patient was treated with landiolol hydrochloride, which is a short-acting beta 1-selective blocker. Minor subcutaneous emphysema around the neck was observed in one patient. POEM was successfully completed, and tracheas were extubated immediately after the procedure in all patients. Our findings suggest that prevention of aspiration pneumonia during anesthesia induction, preparation for carbon dioxide insufflation-related complications, and treatment of scopolamine butylbromide-induced tachycardia play important roles in safe anesthesia management of POEM for esophageal achalasia.

    Forty-eight male and 48 female 6- to 14-week-old kittens were neutered by use of 4 anesthetic protocols. Preanesthetic disposition, depth of sedation, loss of resistance to handling, induction quality, induction time, sternal and stand times, and recovery quality were evaluated. Analgesia and muscle relaxation without supplemental inhalational anesthetics were evaluated in male kittens, and the time until extubation was recorded in female kittens. Intramuscular administration of tiletamine/zolazepam (TZ), midazolam/ketamine, atropine/midazolam/ketamine/butorphanol (AMKB), and atropine/midazolam/ketamine/oxymorphone (AMKO) produced rapid sedation and smooth induction into anesthesia. In male kittens, there were no significant differences in sedation, relaxation, induction time, or quality. Tiletamine/zolazepam administration induced the best analgesia, and midazolam/ketamine administration induced the least analgesia for castration. The recovery time in male kittens was longest with TZ and shortest with the opioid groups (AMKB, AMKO). In females, TZ produced significantly faster induction times, but the degree of sedation and relaxation after administration of injectable agents was not significantly different among the groups. More females given TZ could be intubated without supplemental inhalational agents than females in other groups. Extubation time was rapid in all groups, but the times until sternal and standing were significantly longer, and recovery quality was significantly poorer in females given TZ. In kittens given opioids, reversal of the opioid did not shorten recovery time or improve recovery quality.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8420907

    A prospective controlled trial was conducted to compare the efficacy of an analgesic cream (eutectic mixture of local anesthetics, or EMLA) with a combination of EMLA with hypnosis in the relief of lumbar puncture-induced pain and anxiety in 45 pediatric cancer patients (age 6-16 years). The study also explored whether young patients can be taught and can use hypnosis independently as well as whether the therapeutic benefit depends on hypnotizability. Patients were randomized to 1 of 3 groups: local anesthetic, local anesthetic plus hypnosis, and local anesthetic plus attention. Results confirmed that patients in the local anesthetic plus hypnosis group reported less anticipatory anxiety and less procedure-related pain and anxiety and that they were rated as demonstrating less behavioral distress during the procedure. The level of hypnotizability was significantly associated with the magnitude of treatment benefit, and this benefit was maintained when patients used hypnosis independently. PMID:16719602

    We report successful anesthetic management of extended operation for peritoneal pseudomyxoma combined with massive ascites (16.5 l). A 66-year-old man (weight 76 kg) who could not keep a supine position due to massive ascites associated with peritoneal pseudomyxoma was scheduled for elective peritonectomy and extended surgery. With the patient in the semisitting position, we administered 3% sevoflurane to induce loss of consciousness while preserving spontaneous ventilation. We then performed crush induction with propofol and rocuronium after topical anesthesia to the tongue base. Tracheal intubation with the Macintosh laryngoscope was successful. During the operation, we aspirated about 16.5 l of ascites over 20 l normal saline irrigation. To maintain the body temperature, we performed both active and passive extracorporeal warming. The operation included not only total peritonectomy but also distal gastrectomy, right colon resection, splenectomy, and cholecystectomy. To perform effective postoperative analgesia, we placed two epidural catheters from the upper and lower thoracic epidural spaces. The patient was extubated 3 days after operation, and discharged uneventfully on the 18th postoperative day. PMID:27483656

    Background and Aims: Scars are common and cause functional problems and psychological morbidity. Recent advances in optical technologies have produced various laser systems capable of revising the appearance of scars from various etiologies to optimize their appearance. Methods: Laser treatment can commence as early as the time of the initial injury and as late as several years after the injury. Several optical technologies are currently available and combined laser/light treatments are required for treatment of scars. Since 2006, we have set up a scar management department in our clinic and more than 2000 patients have been treated by our combined laser irradiation techniques. Herein, we review several available light technologies for treatment of surgical, traumatic, and inflammatory scars, and discuss our combined laser treatment of scars, based upon our clinical experience. Results and Conclusions: Because scars have a variety of potential aetiologies and take a number of forms, no single approach can consistenty provide good scar treatment and management. The combination of laser and devices is essential, the choice of wavelength and approach being dictated by each patient as an individual. PMID:24511202

    As of mid-October 2014, the ongoing Ebola epidemic in Western Africa has affected approximately 10,000 patients, approached a 50% mortality rate, and crossed political and geographic borders without precedent. The disease has spread throughout Liberia, Guinea, and Sierra Leone. Isolated cases have arrived in urban centers in Europe and North America. The exponential growth, currently unabated, highlights the urgent need for effective and immediate management protocols for the various health care subspecialties that may care for Ebola virus disease patients. We conducted a comprehensive review of the literature to identify key areas of anesthetic care affected by this disease. The serious potential for "high-risk exposure" and "direct contact" (as defined by the Centers for Disease Control and Prevention) of anesthesiologists caring for Ebola patients prompted this urgent investigation. A search was conducted using MEDLINE/PubMed, MeSH, Cochrane Review, and Google Scholar. Key words included "anesthesia" and/or "ebola" combined with "surgery," "intubation," "laryngoscopy," "bronchoscopy," "stethoscope," "ventilation," "ventilator," "phlebotomy," "venous cannulation," "operating room," "personal protection," "equipment," "aerosol," "respiratory failure," or "needle stick." No language or date limits were applied. We also included secondary-source data from government organizations and scientific societies such as the Centers for Disease Control and Prevention, World Health Organization, American Society of Anesthesiologists, and American College of Surgeons. Articles were reviewed for primary-source data related to inpatient management of Ebola cases as well as evidence-based management guidelines and protocols for the care of Ebola patients in the operative room, infection control, and health care worker personal protection. Two hundred thirty-six articles were identified using the aforementioned terminology in the scientific database search engines. Twenty articles

    Volatile general anesthetics continue to be an important part of clinical anesthesia worldwide. The impact of volatile anesthetics on the immune system has been investigated at both mechanistic and clinical levels, but previous studies have returned conflicting findings due to varied protocols, experimental environments, and subject species. While many of these studies have focused on the immunosuppressive effects of volatile anesthetics, compelling evidence also exists for immunoactivation. Depending on the clinical conditions, immunosuppression and activation due to volatile anesthetics can be either detrimental or beneficial. This review provides a balanced perspective on the anesthetic modulation of innate and adaptive immune responses as well as indirect effectors of immunity. Potential mechanisms of immunomodulation by volatile anesthetics are also discussed. A clearer understanding of these issues will pave the way for clinical guidelines that better account for the impact of volatile anesthetics on the immune system, with the ultimate goal of improving perioperative management.

    Charcot-Marie-Tooth disease (CMTD) is a hereditary peripheral neuropathy and is characterized by progressive muscle atrophy and motor-sensory disorders in all 4 limbs. Most reports have indicated that major challenges with general anesthetic administration in CMTD patients are the appropriate use of nondepolarizing muscle relaxants and preparation for malignant hyperthermia in neuromuscular disease. Moderate sedation may be associated with the same complications as those of general anesthesia, as well as dysfunction of the autonomic nervous system, reduced perioperative respiratory function, difficulty in positioning, and sensitivity to intravenous anesthetic agents. We decided to use intravenous sedation in a CMTD patient and administered midazolam initially and propofol continuously, with total doses of 1.5 mg and 300 mg, respectively. Anesthesia was completed in 3 hours and 30 minutes without adverse events. We suggest that dental anesthetic treatment with propofol and midazolam may be effective for patients with CMTD.

    Patients who have cerebrovascular disease and vascular insufficiency routinely have neurosurgical and nonneurosurgical procedures. Anesthetic priorities must provide a still bloodless operative field while maintaining cardiovascular stability and renal function. Patients who have symptoms or a history of cerebrovascular disease are at increased risk for stroke, cerebral hypoperfusion, and cerebral anoxia. Type of surgery and cardiovascular status are key concerns when considering neuroprotective strategies. Optimization of current condition is important for a good outcome; risks must be weighed against perceived benefits in protecting neurons. Anesthetic use and physiologic manipulations can reduce neurologic injury and assure safe and effective surgical care when cerebral hypoperfusion is a real and significant risk. PMID:16935193

    The purpose of this course is to update nurse anesthetists about anesthetic-induced anaphylaxis. This course discusses the pathophysiologic process of anaphylaxis with descriptions of the allergic immune response and the mediators and mechanisms of mast cell activation. The preoperative identification of patients at high risk and the assessment of potential anesthetic triggers of a hypersensitivity and/or allergic reaction are prudent strategies to minimize the risk of anaphylaxis. Other practices recommended for clinicians include suggestions for anesthetic management to decrease threat of an allergic response in high-risk patients. Furthermore, the identification of the severity grade of hypersensitivity reactions and the appropriate treatment of perioperative anaphylaxis is discussed. In addition, postoperative and follow-up interventions, including testing for patients who have had an anesthetic-induced hypersensitivity reaction, are considered. PMID:22586882

    Anesthetic management of patients undergoing pulmonary vein isolation for atrial fibrillation has specific requirements. The feasibility of non-invasive ventilation (NIV) added to deep sedation procedure was evaluated. Seventy-two patients who underwent ablation procedure were retrospectively revised, performed with (57%) or without (43%) application of NIV (Respironic(®) latex-free total face mask connected to Garbin ventilator-Linde Inc.) during deep sedation (Midazolam 0.01-0.02 mg/kg, fentanyl 2.5-5 μg/kg and propofol: bolus dose 1-1.5 mg/kg, maintenance 2-4 mg/kg/h). In the two groups (NIV vs deep sedation), differences were detected in intraprocedural (pH 7.37 ± 0.05 vs 7.32 ± 0.05, p = 0.001; PaO2 117.10 ± 27.25 vs 148.17 ± 45.29, p = 0.004; PaCO2 43.37 ± 6.91 vs 49.33 ± 7.34, p = 0.002) and in percentage variation with respect to basal values (pH -0.52 ± 0.83 vs -1.44 ± 0.87, p = 0.002; PaCO2 7.21 ± 15.55 vs 34.91 ± 25.76, p = 0.001) of arterial blood gas parameters. Two episodes of respiratory complications, treated with application of NIV, were reported in deep sedation procedure. Endotracheal intubation was not necessary in any case. Adverse events related to electrophysiological procedures and recurrence of atrial fibrillation were recorded, respectively, in 36% and 29% of cases. NIV proved to be feasible in this context and maintained better respiratory homeostasis and better arterial blood gas balance when added to deep sedation. PMID:26937093

    Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome, described by McCarty et al., is a form of "seronegative rheumatoid arthritis" characterized by an acute-onset polyarthritis with pitting edema of the dorsum of both hands and/or both feet. The syndrome is prevalent in elderly men, completely remitted with a small dose of steroid over a relatively short period, and has a benign clinical course. We describe a case of RS3PE syndrome in a 61-year-old man undergoing a lobectomy of the lung and discuss anesthetic management for the syndrome. PMID:15500108

    The internal mammary artery (IMA) has been used as a systemic-to-pulmonary artery shunt in selected patients with congenital heart disease. Growth and development of hypoplastic pulmonary arteries have been described. We discuss the surgical and anesthetic management of an infant with an atretic-thrombosed right pulmonary artery originating from the ascending aorta in whom the IMA was used to create a systemic-to-pulmonary artery shunt after failure of a previous shunt and later successful pulmonary artery reconstruction. The IMA should be considered as an alternative conduit in patients requiring a systemic-to-pulmonary artery shunt for growth of pulmonary arteries. PMID:27290936

    This case report exemplifies the anesthetic technique of blocking bilateral infraorbital and mental nerves for release of contractures of mouth. A 30 year old female patient of post-acid burn contractures of chest wall and mouth was scheduled for contracture release and skin grafting. Airway assessment revealed severe restriction of mouth opening with limited restriction of neck movements. Contracture release of mouth conducted by blocking bilateral infraorbital and mental nerves, which facilitated intubation easily. This case report highlights the practical advantage of nerve blocks for release of contracture mouth, in case of anticipated difficult airway, over other conventional methods. PMID:25948913

    Natural orifice transluminal endoscopic surgery (NOTES) is an evolving field of minimally invasive surgery. NOTES reaches the target organ by inserting the endoscope through a natural orifice (e.g. mouth, anus, urethra, vagina) and offers advantages of less postoperative pain and lower complication rate. Since its first description in 2004, NOTES has progressed from use on animal models to humans. We experienced anesthetic care of two patients who underwent transoral NOTES under general anesthesia.

    No reports have focused on neurological outcomes after open heart surgery of patients with infective endocarditis (IE) and neurological complications. We evaluated parameters related to anesthetic management and neurological outcomes. The subjects analyzed were 24 patients who had undergone valvular surgeries under hypothermic cardiopulmonary bypass from April 1978 to December 1990. The patients were divided into two groups according to the interval between onset of neurological complication and the time of operation: 1) acute group (within one month before the surgery: n = 11, 9.4 +/- 9 days; means +/- SD) and 2) chronic group (more than one month before the surgery: n = 13, 120 +/- 80 days). After heart surgery, 5 patients in the acute group showed newly developed neurological abnormality including death from hemorrhagic transformation, hemiplegia or aphasia. No patients in the chronic group had newly developed neurological abnormality related to the surgery. In the neurologically deteriorated patients of the acute group, interval from the onset of neurological complication to surgery was 3.5 +/- 4.5 days, whereas that of the remainders of the acute group was significantly longer (14.4 +/- 9.0 days). Intraoperative events and anesthetic management of these patients were also analyzed. However, there were no significant differences in the parameters such as cerebral perfusion pressure, arterial PaCO2, doses of anesthetics and use of vasopressors. Our results suggest that the most important factor which may influence neurological outcome was the interval between the onset of neurological abnormality and the time of operation.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7861608

    Background. Hazards of liver surgery have been attenuated by the evolution in methods of hepatic vascular control and the anesthetic management. In this paper, the anesthetic considerations during hepatic vascular occlusion techniques were reviewed. Methods. A Medline literature search using the terms “anesthetic,” “anesthesia,” “liver,” “hepatectomy,” “inflow,” “outflow occlusion,” “Pringle,” “hemodynamic,” “air embolism,” “blood loss,” “transfusion,” “ischemia-reperfusion,” “preconditioning,” was performed. Results. Task-orientated anesthetic management, according to the performed method of hepatic vascular occlusion, ameliorates the surgical outcome and improves the morbidity and mortality rates, following liver surgery. Conclusions. Hepatic vascular occlusion techniques share common anesthetic considerations in terms of preoperative assessment, monitoring, induction, and maintenance of anesthesia. On the other hand, the hemodynamic management, the prevention of vascular air embolism, blood transfusion, and liver injury are plausible when the anesthetic plan is scheduled according to the method of hepatic vascular occlusion performed.

    We consider that general anesthesia will be an appropriate and safe method as regional methods could lead to significant time loss in the prevention or minimization of complications. High blockage required for regional anesthetic methods in pregnant women with TGA and the maintenance of hemodynamic stability may become difficult due to neuroaxial sympathectomy even if a successful neuroaxial block has been provided. Agents with minimal effect on cardiovascular functions should be preferred for anesthesia induction and maintenance and close hemodynamic monitoring should be done during intraoperative and postoperative periods.

    This review summarizes current knowledge concerning incidence, risk factors, and mechanisms of perioperative nerve injury, with focus on local anesthetic-induced neurotoxicity. Perioperative nerve injury is a complex phenomenon and can be caused by a number of clinical factors. Anesthetic risk factors for perioperative nerve injury include regional block technique, patient risk factors, and local anesthetic-induced neurotoxicity. Surgery can lead to nerve damage by use of tourniquets or by direct mechanical stress on nerves, such as traction, transection, compression, contusion, ischemia, and stretching. Current literature suggests that the majority of perioperative nerve injuries are unrelated to regional anesthesia. Besides the blockade of sodium channels which is responsible for the anesthetic effect, systemic local anesthetics can have a positive influence on the inflammatory response and the hemostatic system in the perioperative period. However, next to these beneficial effects, local anesthetics exhibit time and dose-dependent toxicity to a variety of tissues, including nerves. There is equivocal experimental evidence that the toxicity varies among local anesthetics. Even though the precise order of events during local anesthetic-induced neurotoxicity is not clear, possible cellular mechanisms have been identified. These include the intrinsic caspase-pathway, PI3K-pathway, and MAPK-pathways. Further research will need to determine whether these pathways are non-specifically activated by local anesthetics, or whether there is a single common precipitating factor. PMID:26959012

    A 70-year-old man with Becker muscular dystrophy (BMD) underwent laparoscopic rectopexy under general anesthesia. For anesthetic induction, we administered total 0.6 mg · kg-1 of rocuronium with titration. Eight minutes later, train-of-four (TOF) count reached to 0 and the patient was intubated smoothly. One hundred and five minutes later, TOF ratio recovered to 100% and we administered rocuronium 10 mg additionally. Surgery was finished without any problems 95 minutes after thereafter. TOF ratio was 45% and we administered sugammadex 3 mg · kg-1, reversing neuromuscular blockade to TOF ratio 100% within 1.5 minute. The patient awoke clearly and respiratory condition was good. He was extubated without remaining neuromuscular blockade. Postoperative course was stable and there was no serious adverse effect on his muscular function intra- and post-operatively. In conclusion, rocuronium and sugammadex can be used safely and effectively in general anesthetic management for patients with muscular dystrophy. However, as the onset times and durations of these agents can be longer, we should administer these agents with titration carefully under periodic neuromuscular monitoring. PMID:25693344

    Although maintaining anesthesia for myasthenia gravis (MG) with minimal muscle relaxants (MR) is common, the success rate of anesthetic management for MG without MR is not clear. We therefore retrospectively examined the success rate of anesthetic management for MG without MR among 66 consecutive cases of thymectomy for MG performed at our hospital between January 2004 and April 2010, before approval of using sugammadex. A total of 60 patients (90.9 %) were treated without MR (N group). Among the 60 cases, 17 (28.3 %) patients were not extubated in the operating room due to postoperative respiratory depression or other reasons. Therefore, the success rate of anesthetic management for thymectomy in patients with MG without treating MR was 71.7 % (43/60) [95 % confident interval (CI): 65.9-77.5 %]. The reasons for using MR included coughing at intubation in one case, bucking during surgery in two cases, and MR was considered to be safer by the attending anesthesiologist in three cases. The number of cases of impossible extubation requiring ventilation on that day was three in the N group and none in the R group. Finally, the success rate of anesthetic management for MG without MR was estimated to be 71.1 % (95 % CI: 65.9-77.5 %). PMID:25796520

    The presence of co-morbidities during pregnancy can pose numerous challenges to the attending anesthesiologists during operative deliveries or during the provision of labor analgesia services. The presence of cardiac diseases, endocrinological disorders, respiratory diseases, renal pathologies, hepatic dysfunction, anemia, neurological and musculoskeletal disorders, connective tissue diseases and many others not only influence the obstetric outcome, but can significantly impact the anesthetic technique. The choice of anesthesia during the pregnancy depends upon the type of surgery, the period of gestation, the site of surgery, general condition of patient and so on. Whatever, the anesthetic technique is chosen the methodology should be based on evidentially supported literature and the clinical judgment of the attending anesthesiologist. The list of co-morbid diseases is unending. However, the present review describes the common co-morbidities encountered during pregnancy and their anesthetic management during operative deliveries.

    In this retrospective study, we describe the anesthetic management and its implications in parturients with chronic kidney disease (CKD; n = 9), who underwent elective caesarean delivery. Nine parturients with CKD of various etiologies, who underwent elective Caesarean delivery, were included in this study. Spinal anest-hesia was administered in all parturients with normal coagulation profile through a 25-gauze spinal needle (Quincke) with 0.5% (H) bupivacaine in L2-3 space and T6 level was achieved. Hemodynamics and side effects such as nausea, vomiting, headache, and backache were record. The mean age was 28.22 ± 4.43 years. The mean levels of serum creatinine and serum potassium were 2.78 ± 1.29 mg/dl and 4.11 ± 0.46 meq/l, respectively. Mean baseline values of systolic blood pressure, diastolic blood pressure, and pulse rate were higher which decreased after spinal anesthesia. However, the incidence of hypotension, which required mephentermine treatment, was 11.1%. One patient had symptoms of nausea and vomiting/dizziness at the time of hypotension, which disappeared after treatment with 5 mg of intravenous mephentermine. Baseline value of PR remained high throughout the operation. Parturients with CKD with normal coagulation profile remained hemodynamically stable under spinal anesthesia with minimal side effects. However, a large number of studies are required to determine the safety of spinal anesthesia in this setting. PMID:24574626

    We report the anesthetic management of a pediatric case of blue rubber bleb nevi syndrome combined with small-intestinal intussusception. A 2-year-old girl was transferred to our hospital for small-intestinal intussusception. Emergent ablation of the upper gastrointestinal tract nevus under general anesthesia was planned. Given the presence of several nevi in the oral and pharyngeal space, we utilized the McGRATH MAC (McGRATH; Aircraft Medical Ltd, United Kingdom) laryngoscope for gentle and stress-free tracheal intubation. The venous line was kept patent preoperatively, and rapid-sequence intubation was performed with the McGRATH (size 2 pediatric blade). A 4.5-mm tracheal tube was inserted uneventfully under direct visualization. The trachea was observed and the tube maintained in a proper position with a bronchofiberscope. During the procedure, cuff volume was regulated to avoid excessive increase by upper gastrointestinal endoscope insertion. The girl was extubated in the operating room and showed no postoperative complications such as hemorrhage or hoarseness. PMID:27188112

    In the present study, we investigated the efficacy of local anesthetics soaked non-absorbable sinus packs on pain management after functional endoscopic surgery (FESS). One hundred and fifty patients with the diagnosis of bilateral chronic sinusitis with or without nasal polyps who underwent FESS were included into the study. Their pre-operative Lund-Mackay computerized tomography (CT) Scores were similar. We applied anesthetic agents of 2 % lidocaine HCl, 0.25 % Bupivacaine HCl, 0.2 % Ropivacaine, 2 % Prilocaine and 0.9 % NaCl (Saline) in groups 1-5 onto the sinus packs after FESS. At postoperative period, acetaminophen (250 mg/5 ml) was used in 10-15 mg/kg per dose (4 times a day). Bleeding grade, operation duration, postoperative number of gauze/24 h, additional painkiller need, pain values at 1, 2, 4, 8, 12 and 24 h were noted. Lund-Kennedy endoscopic scores were also evaluated at 1st, 2nd and 4th weeks postoperatively. In saline group, 93.3 % of the patients needed additional painkiller. Whereas, in Bupivacaine group, additional painkiller use (20.0 %) is less than the other groups. In Bupivacaine group, number of gauze/24 h use was lower than lidocaine, ropivacaine and prilocaine groups. In our study, except 1st and 24th hours, pain values of groups can be written in ascending order (from less to higher) as Bupivacaine, Lidocaine, Prilocaine, Ropivacaine and Saline. In the first hour, pain values of groups can be written in ascending order (from less to higher) as Lidocaine, Prilocaine, Bupivacaine, Ropivacaine and Saline. In the 2nd week, in the Bupivacaine and Lidocaine Groups separately, postoperative Lund-Kennedy scores were lower than the Prilocaine and Saline Groups. In the 1st month, Lidocaine Group's Lund-Kennedy scores were significantly lower than the Saline Group. Synechia values were not different between groups. Bupivacaine help the lower pain values and less additional painkiller need after FESS. Therefore, we recommend to use

    Uncontrolled hyperthyroidism is a risk factor of perioperative thyrotoxic crisis. We report a case of a 61-year-old woman with thyrotoxicosis diagnosed with unstable angina pectoris. She needed to have an early scheduled coronay artery bypass grafting surgery, because percutaneous intervention for the left main coronary artery in support of intra-aortic balloon pumping (IABP) resulted in failure. Tachycardia and hyperthermia were observed at admission to the ICU, and hemodynamic parameters suggested high-output heart failure. Preoperative management using antithyroid drug, inorganic iodine, corticosteroid and propranolol stabilized her hemodynamic condition, and then CABG was performed on ICU day 3. Intraoperative and postoperative use of landiolol, a short acting beta blocker, was useful for maintaining hemodynamic stability. Surgery was uneventfully completed and she was extubated on postoperative day 1 following IABP withdrawal. Appropriate preoperative management and perioperative use of the short acting beta blocker were useful for management of the patient with uncontrolled hyperthyroid state. PMID:24228459

    2016-07-01

    Acute ischemic stroke (AIS) is a devastating condition with high morbidity and mortality. In the past 2 decades, the treatment of AIS has been revolutionized by the introduction of several interventions supported by class I evidence-care on a stroke unit, intravenous tissue plasminogen activator within 4.5 hours of stroke onset, aspirin commenced within 48 hours of stroke onset, and decompressive craniectomy for supratentorial malignant hemispheric cerebral infarction. There is new class I evidence also demonstrating benefits of endovascular therapy on functional outcomes in those with anterior circulation stroke. In addition, the importance of the careful management of key systemic physiological variables, including oxygenation, blood pressure, temperature, and serum glucose, has been appreciated. In line with this, the role of anesthesiologists and intensivists in managing AIS has increased. This review highlights the main challenges in the endovascular and intensive care management of AIS that, in part, result from the paucity of research focused on these areas. It also provides guidelines for the management of AIS based upon current evidence, and identifies areas for further research. PMID:26368664

    We report a case of partial lobectomy in a patient with Marfan syndrome. A 56-year-old woman with Marfan syndrome was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. She underwent a Bentall operation and mitral valve replacement 10 months before and strict blood pressure management was required. After induction of general anesthesia with propofol and fentanyl, topical intratracheal lidocaine anesthesia was performed using the Pentax-AWS Airwayscope (AWS) for visualization, allowing for the Soft-tipped Tube Exchanger (TE-Soft) to be inserted into the trachea. Next, a double-lumen tracheal tube was uneventfully intubated via the TE-Soft with minimal change in vital signs. During the operation, pressure-controlled ventilation was performed to minimize the risk of pneumothorax. After the operation, under continuous administration of landiorol and dexmedetomidine, the double-lumen tracheal tube was extubated uneventfully. Strict airway and circulation management is needed for lung or vessel preservation in patients whose conditions are complicated by Marfan syndrome. PMID:26422961

The patient was scheduled to undergo thoracic decompression laminectomy and instrumentation. Markedly severe hemodynamic fluctuations happened during the manipulation of the tumor and continued after the tumor was removed. After multimodal antihypertensive therapy the vital signs were adequately managed and the surgery was successfully performed without complications. The patient was discharged without any sequelae ten days later. The pathology report indicated the diagnosis of extra-adrenal pheochromocytoma. Unexpected pheochromocytoma may lead to a fatal hypertensive crisis during surgery.

    Secondary hyperthyroidism can often complicate gestational trophoblastic disease, a malignant uterine cancer. We report here the perioperative management of hyperthyroidism due to hydatidiform mole. A 53-year-old woman underwent emergency surgery due to suspicion of hydatidiform mole. Tachycardiac atrial fibrillation was detected by electrocardiography at the preoperative examination. No abnormalities were found in blood count, coagulation, biochemical tests, chest radiographs, or respiratory function. General anesthesia with nitrous oxide, oxygen, and sevoflurane, combined with fentanyl and 1% mepivacaine, was administered intermittently from an epidural catheter. Intraoperative events included hypotension and tachycardia, although in general, tachycardia was prevented with antiarrhythmic agents and transfusion with a plasma expander and crystalloid fluid. Hyperthyroidism was highly suspected from the patient's clinical course and was confirmed by high levels of preoperative serum free triiodothyronine (T3) and thyroxine (T4). The patient became euthyroid within a few days after mole evacuation and did not require an antiarrhythmic agent after her return to the inpatient ward. PMID:19921374

    Maternal complete heart block can pose significant challenges for the anesthesiologist in the antepartum, peripartum, and postpartum periods. Some patients may present for the first time in the puerperium with dizziness, weakness, syncope, or congestive heart failure as a result of the additional hemodynamic burden that accompanies pregnancy. Although there is an increase in permanent pacemaker placement in young symptomatic patients before pregnancy, prophylactic placement of pacemakers in asymptomatic parturients is not always indicated. The need for temporary or permanent pacemakers in asymptomatic women should be assessed on a case-by-case basis; many of these patients may be safely managed during labor and delivery without pacing. The parturient with complete heart block must be followed vigilantly during pregnancy and post delivery, as the need for pacemaker insertion can also arise in the postpartum period. We present a case of third-degree heart block in a 26-year-old parturient. PMID:27555134

    It has been demonstrated that laparoscopic surgery can reduce surgical trauma and postoperative pain, allowing earlier recovery and hospital discharge. However, because patients with severe cardiac depression may not tolerate the adverse respiratory and cardiovascular effects of pneumoperitoneum with a head-up or head-down tilt position, laparoscopic surgery has been avoided in these patients. The present case with low ventricular function (ejection fraction=23-27%) due to cardiac sarcoidosis could successfully undergo laparoscopic sigmoidectomy by using pulmonary artery catheterization. Therefore, laparoscopic surgery can be performed in patients with cardiac dysfunction if the cardiopulmonary responses caused by pneumoperitoneum with a head-up or head-down tilt are sufficiently considered and adverse hemodynamic responses appropriately detected and treated through invasive monitoring techniques such as pulmonary artery catheterization and/or transesophageal echocardiography.

    In this case, inappropriately labeling the child as "allergic to local anesthetics", resulted in her inability to receive appropriate dental care. It was a major disservice to her and led to the potentially serious consequences of neglecting the dental disease present. The small caries lesions that would have required amalgam restorations at five years of age progressed to painful toothaches requiring stainless steel crowns and pulpal treatment. Although adverse reactions to local anesthetics are uncommon, most dentists can anticipate encountering a patient who will have an adverse reaction to a local anesthetic. This case ilustrates the need for dentists to be knowledgeable regarding the signs and symptoms of the potential adverse reactions and their appropriate management. Most importantly, prevention is based upon knowledge of anatomy, dose determination, and the use of proper armamentarium and technique, which are key factors in making a safe and effective drug even safer.

    Here, we report successful anesthetic management of posterior cervical spinal fusion utilizing block of the frontal nerve, the greater occipital nerve, and the superficial cervical plexus in a patient with athetoid cerebral palsy. A 69-year-old woman (height 157 cm; weight 33 kg) with athetoid cerebral palsy was scheduled to undergo posterior cervical spinal fusion for cervical spondylotic myelopathy. After induction of general anesthesia, we performed tracheal intubation using the Pentax-AWS Airwayscope with a thin Intlock. After tracheal intubation, we used ropivacaine for the frontal nerve, greater occipital nerve, and superficial cervical plexus block. Anesthetic maintenance was performed with total intravenous anesthesia utilizing propofol and remifentanil. Continuous administration of dexmedetomidine was started during operation. Following surgery, smooth spontaneous ventilation was observed following uneventful extubation. No significant pain and no athetoid movement were observed under continuous administration of dexmedetomidine. PMID:26422967

    It is very difficult to decide the best time to deliver the baby for a pregnant woman with advanced cancer. We experienced the perioperative and perinatal management of a 39-year-old pregnant woman with advanced tongue cancer. The cancer had already metastasized to the lung and lymph nodes. Furthermore a recurrent thumb-sized tumor was found in her mouth. She had firmly desired to discontinue all anticancer treatment for protecting the fetus. On the other hand, her family could not accept her determination yet. Therefore the medical team was organized with doctors and co-medicals from multiple departments such as gynecology, pediatrics, radiology, oncology, midwife, psychotherapy and anesthesiology. After several conferences including herself and family, finally cesarean section was scheduled for the 30th gestational week. Prepared for unexpected emergency delivery, airway stenosis was ruled out by fiberoptic laryngoscopy and the consent for emergency tracheostomy was obtained. The operation was performed successfully under spinal anesthesia without any severe troubles. Medical care as a team from early phase enabled elaborate observation and preparation through the perioperative and perinatal period. Furthermore, it was efficient to provide satisfaction to the patient and her family as well. PMID:27483663

    We report on a child with moyamoya disease combined with von Gierke's disease. A 7-year-old girl with von Gierke's disease had a stroke associated with moyamoya disease. She had had many episodes of hypoglycemia and severe metabolic acidosis before surgery. General anesthesia was induced with midazolam 3 mg and fentanyl 100 microg followed by rocuronium 12 mg. After tracheal intubation, anesthesia was maintained with sevoflurane 2.5% in 33% oxygen and 66% nitrous oxide. We used mainly mixture of saline and glucose as intraoperative fluid instead of acetated Ringer solution, and controlled administration of glucose according to blood glucose levels. The patient's plasma lactate levels and base excess during operation showed changes compared with those before operation, because sodium bicarbonate was used during the surgery. The duration of anesthesia was 374 minutes. The patient woke up and spontaneous respiration returned, and the trachea was extubated in the operating room. We were able to manage this case safely without any complications. PMID:20169974

    For several decades, anesthetic gases have greatly enhanced the comfort and outcome for patients during surgery. The benefits of these agents have heavily outweighed the risks. In recent years, the attention towards their overall contribution to global climate change and the environment has increased. Anesthesia providers have a responsibility to minimize unnecessary atmospheric pollution by utilizing techniques that can lessen any adverse effects of these gases on the environment. Moreover, health care facilities that use anesthetic gases are accountable for ensuring that all anesthesia equipment, including the scavenging system, is effective and routinely maintained. Implementing preventive practices and simple strategies can promote the safest and most healthy environment. PMID:23241038

    Purpose The aim of the present clinical trial was to compare pain during injection of anterior middle superior alveolar (AMSA) technique with that of infiltration injection technique in the maxilla in periodontal flap surgeries of patients referring to the Department of Periodontics, Faculty of Dentistry, Tabriz University of Medical Sciences. Methods Twenty subjects with an age range of 20 to 40 years were selected for the present study. One side of the maxilla was randomly selected as the test side and the other as the control side using a flip of a coin. AMSA technique was used on the test side and infiltration technique was used on the control side for anesthesia. On both sides 2% lidocaine containing 1:80,000 epinephrine was used for anesthesia. The operator obtained the visual analogue scale for each patient immediately after the injection and immediately after surgery. Data was analyzed using descriptive statistical methods (frequency percentages, means and standard deviations) and Wilcoxon's test using SPSS ver. 13 (SPSS Inc.). Statistical significance was defined at P<0.05. Results There were no statistically significant differences in pain during injection between the two techniques (P=0.856). There were statistically significant differences in postoperative pain between the two injection techniques (P=0.024). Conclusions Postoperative pain in AMSA injection technique was less than that in the infiltration technique. Therefore, the AMSA technique is preferable in the periodontal surgeries for the anesthesia of palatal tissues given the fact that it has other advantages, too. PMID:22586522

    : This study aims to describe a new technique for the management of auricular hematoma using fibrin glue. Five difficult cases of auricular hematoma were managed using this technique, including 2 recurrent and 3 delayed presentations. After skin preparation and local anesthetic, an incision was made, the hematoma was evacuated, and the cavity was washed out with saline. Fibrin glue was applied liberally; a dental roll pressure dressing was applied and secured with a prolene bead suture. The patients were given a course of oral antibiotic and reviewed after 5 days for removal of the external dressing. They were later assessed to exclude re-accumulation of the hematoma. All patients had complete resolution of the hematoma without re-accumulation; they were satisfied with the cosmetic results and experienced no complications. This case series provides evidence that fibrin glue is effective in the management of auricular hematoma. Larger studies may provide further evidence of the effectiveness of this new technique.

  17. Lipid Emulsion for Local Anesthetic Systemic Toxicity

    2012-01-01

    The accidental overdose of local anesthetics may prove fatal. The commonly used amide local anesthetics have varying adverse effects on the myocardium, and beyond a certain dose all are capable of causing death. Local anesthetics are the most frequently used drugs amongst anesthetists and although uncommon, local anaesthetic systemic toxicity accounts for a high proportion of mortality, with local anaesthetic-induced cardiac arrest particularly resistant to standard resuscitation methods. Over the last decade, there has been convincing evidence of intravenous lipid emulsions as a rescue in local anesthetic-cardiotoxicity, and anesthetic organisations, over the globe have developed guidelines on the use of this drug. Despite this, awareness amongst practitioners appears to be lacking. All who use local anesthetics in their practice should have an appreciation of patients at high risk of toxicity, early symptoms and signs of toxicity, preventative measures when using local anesthetics, and the initial management of systemic toxicity with intravenous lipid emulsion. In this paper we intend to discuss the pharmacology and pathophysiology of local anesthetics and toxicity, and the rationale for lipid emulsion therapy. PMID:21969824

    We describe a case of living unrelated renal transplantation from a non-malignant hyperthermia (MH) susceptible donor to an MH-susceptible recipient, along with its intraoperative and perioperative considerations. The renal transplant recipient reported a personal history of MH requiring intensive care unit admission. A nontriggering anesthetic was therefore chosen for the unrelated donor to avoid possible triggering via the transplanted kidney to the MH-susceptible recipient. This case provides a unique opportunity to review the concepts of antigen transfer related to transplant anesthesia, as well as the importance of communication among anesthesia and surgical teams to promote patient safety.

    PURPOSE: To date, there has been no comparison of outcomes in women undergoing anesthesia for in vitro fertilization (IVF) oocyte retrieval for the purpose of pre-implantation genetic diagnosis (PGD) because of their or their partner's genetic disease relative to the outcome in women requiring IVF because of fertility issues. MATERIALS AND METHODS: A prospective observational study, wherein all demographic and anesthetic management data were collected from IVF and PGD units' records for a 6-month period. Descriptive analyses and parametric tests were employed. RESULTS: There were 307 cases IVF and 76 cases PGD: most (97.4% and 99.7%, respectively) received general anesthesia with propofol and fentanyl ± dipyrone (90.5% and 93.3%, respectively) with no adverse effects. The only statistically significant difference between IVF and PGD groups that was potentially clinically significant was post-procedure recovery time (23.0 ± 20.4 vs. 29.4 ± 35.8 min, respectively; P < 0.0001), but is explainable as greater caution by Anesthesiologists for higher-risk PGD cases having autosomal dominant diseases that may impact anesthesia management (myotonic dystrophy, neurofibromatosis, Marfan's); two of these cases also recovered in the general post-anesthesia care unit, as a precaution for early diagnosis and treatment of potential post-procedural complication. CONCLUSIONS: Results of this first-ever survey of anesthesia for PGD compared with IVF cases imply that propofol-and-fentanyl-based anesthesia is safe and can be recommended, bearing in mind that with patients who have autosomal dominant diseases impacting anesthetic management it is prudent to be more cautious post-recovery.

    We report a case of large thyroid carcinoma with tracheal and esophageal invasion who presented with preoperative stridor scheduled for total thyroidectomy and segmental tracheal resection. Careful and comprehensive preoperative anesthetic planning was done. Extracorporeal circulation membrane oxygenation (ECMO) was set up and running prior to induction under local anesthesia, due to an increased international normalized ratio (INR) and fear of bleeding in the airway. Fiberoptic bronchoscopy (FOB) is the first choice in many circumstances of difficult airway. However, we twice failed to intubate under FOB guidance. Successful intubation was done with traditional laryngoscopy and a Glidescope. The operative course was smooth. The oral endotracheal tube (ETT) was changed to a nasal ETT after surgery with the Glidescope. FOB-assisted intubation carries a chance of failure, and in critical patients, the presence of other intubating modalities such as video-assisted or fiberoptic-assisted technology or safety measures, including ECMO, will greatly increase the safety of anesthesia and surgery.

    We report the successful anesthetic management of video-assisted left upper lobectomy in a patient with ischemic heart disease using an intra-aortic balloon pump (IABP). An 81-year-old man with severe ischemic heart disease was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. Although he had severe ischemic heart disease, coronary intervention such as percutaneous cardiac intervention or coronary artery bypass grafting was impossible due to severe coronary stenosis. IABP was instituted through the femoral artery before inducing anesthesia. Tracheal intubation was performed with the McGRATH MAC videolaryngoscope to minimize stress. Surgery was performed uneventfully and the patient was transferred to the intensive care unit under sedation. IABP was removed three hours postoperatively. After confirming no ischemic or vital sign changes, he was extubated the next day. No complications resulting from the IABP were observed. PMID:27188114

    Since William Morton successfully demonstrated the use of inhaled ether for surgical anesthesia in 1846, the development of new anesthetics and safe general anesthesia techniques have contributed greatly to the advancement of surgery and other invasive procedures. However, the underlying neurocellular mechanisms by which the state of general anesthesia is achieved are only just beginning to be understood. The general anesthetic state comprises multiple components (amnesia, unconsciousness, analgesia, and immobility), each of which is mediated by effects on different neurotransmitter receptors and neuronal pathways. In this review, we focus on the mechanisms of action of inhaled and intravenous, and we describe the neuronal systems thought to be involved in mediating the clinically relevant actions of general anesthetics. We then describe the neurotransmitter receptors that are the principal targets of many general anesthetics, in particular ã-aminobutyric acid type A receptor subtypes. PMID:24389218

    Introduction The contemporary parents are more active and participate in the decision making during dental treatment. Aim To assess the parents’ acceptance towards behavior management techniques commonly used in the pediatric dentistry in different dental situation. Materials and Methods Fifty-one parents participated in the study. Children’s dental fear was assessed by the parents before attending power point presentation using Dental Subscale of the Children’s Fear Survey Schedule (CFSS-DS). Parents viewed power point presentation of eight behavior management techniques being used during pediatric dental treatment. The techniques were: 1) Voice control; 2) Tell-Show-Do; 3) Positive reinforcement; 4) Parental presence or absence; 5) HOME; 6) Physical restraint; 7) N2O-O2 sedation; 8) General anesthesia. Parents were asked to arrange various behavior management techniques from most accepted technique to least accepted technique in various dental situations according to their view. Results All the parents completed the questionnaire. Most children show increased anxiety related to dental component of CFSS-DS scale particularly during the administration of local anesthetic. In present study most preferred behavior management technique was Tell-Show-Do followed by positive reinforcement and least preferred behavior management technique was general anesthesia followed by physical restraint. Conclusion Children’s anxiety level increases during the condition related to dentistry which can be overcome by developing positive approach in children and parents towards dentistry and by utilizing various behaviour management strategies. A generalized low parental tolerance level for firm management techniques was seen in the present study population.

    Pediatric patients with pulmonary alveolar proteinosis require whole lung lavage to clear the accumulation of lipoproteinaceous material within the alveoli, to maintain respiratory function. Anesthesia for this presents a challenge due to preexisting respiratory failure, and the small diameter and length of the pediatric airway, which is often unable to accommodate existing one-lung isolation and ventilation equipment. Novel techniques to facilitate lung lavage on seven occasions are described and placed in the context of the existing literature to date. PMID:25664978

    From time immemorial, animals have served as models for humans. Like humans, animals too have to undergo several types of elective and emergency surgeries. Several anesthetic techniques and drugs used in humans are also used in animals. However, unlike humans, the animal kingdom includes a wide variety of species, breeds, and sizes. Different species have variable pharmacological responses, anatomy, temperament, behavior, and lifestyles. The anesthetic techniques and drugs have to suit different species and breeds. Nevertheless, there are several drugs and many peculiar anesthetic techniques used in animals but not in human beings. Keeping this in mind, literature was hand searched and electronically searched using the words “veterinary anesthesia,” “anesthetic drugs and techniques in animals” using Google search engine. The interesting information so collected is presented in this article which highlights some challenging and amazing aspects of anesthetizing animals including the preanesthetic assessment, preparation, premedication, monitoring, induction of general anesthesia, intubation, equipment, regional blocks, neuraxial block, and perioperative complications.

    As innovative technology continues to be developed and is implemented into the realm of cardiac surgery, surgical teams, cardiothoracic anesthesiologists, and health centers are constantly looking for methods to improve patient outcomes and satisfaction. One of the more recent developments in cardiac surgical practice is minimally invasive robotic surgery. Its use has been documented in numerous publications, and its use has proliferated significantly over the past 15 years. The anesthesiology team must continue to develop and perfect special techniques to manage these patients perioperatively including lung isolation techniques and transesophageal echocardiography (TEE). This review article of recent scientific data and personal experience serves to explain some of the challenges, which the anesthetic team must manage, including patient and procedural factors, complications from one-lung ventilation (OLV) including hypoxia and hypercapnia, capnothorax, percutaneous cannulation for cardiopulmonary bypass, TEE guidance, as well as methods of intraoperative monitoring and analgesia. As existing minimally invasive techniques are perfected, and newer innovations are demonstrated, it is imperative that the cardiothoracic anesthesiologist must improve and maintain skills to guide these patients safely through the robotic procedure.

    Background and Objectives A hardcopy or paper cognitive aid has been shown to improve performance during the management of simulated local anesthetic systemic toxicity (LAST) when given to the team leader. However, there remains room for improvement in order to ensure a system that can achieve perfect adherence to the published guidelines for LAST management. Recent research has shown that implementing a checklist via a designated reader may be of benefit. Accordingly, we sought to investigate the effect of an electronic decision support tool (DST) and designated ‘Reader’ role on team performance during an in-situ simulation of LAST. Methods Participants were randomized to Reader+DST (N = 16, rDST) and Control (N = 15, memory alone). The rDST group received the assistance of a dedicated Reader on the response team who was equipped with an electronic DST. The primary outcome measure was adherence to guidelines. Results For overall and critical percent correct scores, the rDST group scored higher than Control (99.3% vs 72.2%, P < 0.0001; 99.5% vs 70%, P < 0.0001, respectively). In the LAST scenario, 0 of 15 (0%) in the control group performed 100% of critical management steps, while 15 of 16 (93.8%) in the rDST group did so (P < 0.0001). Conclusions In a prospective, randomized single-blinded study, a designated Reader with an electronic DST improved adherence to guidelines in the management of an in-situ simulation of LAST. Such tools are promising in the future of medicine, but further research is needed to ensure the best methods for implementing them in the clinical arena. PMID:24956454

    In the recent decade, nonintubated-intubated video-assisted thoracoscopic surgery (VATS) has been extensively performed and evaluated. The indicated surgical procedures and suitable patient groups are steadily increasing. Perioperative anesthetic management presents itself as a fresh issue for the iatrogenic open pneumothorax, which is intended for unilateral lung collapse to create a steady surgical field, and the ensuing physiologic derangement involving ventilatory and hemodynamic perspectives. With appropriate monitoring, meticulous employment of regional anesthesia, sedation, vagal block, and ventilatory support, nonintubated VATS is proved to be a safe alternative to the conventional intubated general anesthesia.

    Despite numerous previous studies, there is little data on the effects of anesthetics on clinical outcome after off-pump coronary arterial bypass grafting (OPCAB). Therefore, we retrospectively compared the effects of anesthetic choice on in-hospital major adverse events (MAEs) and one-year major adverse cardiovascular and cerebral events (MACCEs) in patients undergoing OPCAB. Electronic medical records were reviewed in 192 patients who received propofol-remifenanil total intravenous anesthesia (TIVA) and propensity score-matched 662 patients who received isoflurane anesthesia. The primary endpoints were in-hospital MAEs and one-year MACCEs. The components of in-hospital MAEs were in-hospital death, myocardial infarction (MI), coronary revascularization, stroke, renal failure, prolonged mechanical ventilation longer than 72 h, and postoperative new cardiac arrhythmia requiring treatment. One-year MACCEs was defined as a composite of all-cause mortality, MI, coronary revascularization, and stroke. There was no significant difference in risk of in-hospital MAEs (OR = 1.29, 95% CI = 0.88–1.88, P = 0.20) or one-year MACCEs (OR = 0.81; 95% CI = 0.46–1.42, P = 0.46) between the groups. The risk of postoperative new arrhythmia including new atrial fibrillation significantly increased in the TIVA group compared to the isoflurane anesthesia group (OR = 1.72, 95% CI = 1.12–2.63, P = 0.01). In conclusion, the choice between propofol-remifentanil TIVA and isoflurane anesthesia did not show differences in incidence of in-hospital MAEs or one-year MACCEs in patients undergoing OPCAB. However, further studies on the effects of anesthetics on development of in-hospital new arrhythmia will be needed. PMID:27054364

    Minimally invasive therapy aims to minimize the trauma of any interventional process but still achieve a satisfactory therapeutic result. The development of "critical pathways," rapid mobilization and early feeding have contributed towards the goal of shorter hospital stay. This concept has been extended to include laparoscopic cholecystectomy and hernia repair. Reports have been published confirming the safety of same day discharge for the majority of patients. However, we would caution against overenthusiastic ambulatory laparoscopic cholecystectomy on the rational but unproven assumption that early discharge will lead to occasional delays in diagnosis and management of postoperative complications. Intraoperative complications of laparoscopic surgery are mostly due to traumatic injuries sustained during blind trocar insertion and physiologic changes associated with patient positioning and pneumoperitoneum creation. General anesthesia and controlled ventilation comprise the accepted anesthetic technique to reduce the increase in PaCO2. Investigators have recently documented the cardiorespiratory compromise associated with upper abdominal laparoscopic surgery, and particular emphasis is placed on careful perioperative monitoring of ASA III-IV patients during insufflation. Setting limits on the inflationary pressure is advised in these patients. Anesthesiologists must maintain a high index of suspicion for complications such as gas embolism, extraperitoneal insufflation and surgical emphysema, pneumothorax and pneumomediastinum. Postoperative nausea and vomiting are among the most common and distressing symptoms after laparoscopic surgery. A highly potent and selective 5-HT3 receptor antagonist, ondansetron, has proven to be an effective oral and IV prophylaxis against postoperative emesis in preliminary studies. Opioids remain an important component of the anesthesia technique, although the introduction of newer potent NSAIDs may diminish their use. A preoperative

    The intravascular administration and the high blood resorption of local anesthetic agents are known to induce neurotoxic accidents. However, the use of potent local anesthetic drugs such as bupivacaine is responsible for serious cardiotoxic accidents with a mortality of about 50%. Indeed, bupivacaine induces both electrophysiologic and haemodynamic disturbances with the occurrence of conduction blocks, arrhythmias and cardiovascular collapse. Moreover, cardiotoxicity is worsened by: bupivacaine-induced sympathetic activation which facilitates tachycardia and arrhythmias, metabolic abnormalities such as hypoxia, acidosis, hyperkaliemia and hypothermia, pregnancy, diazepam pretreatment, and the antiarrhythmic drugs. In case of cardiac arrest, CPR must be made. In the other cases, the first treatment is to oxygenate, to intubate the trachea and to ventilate the lungs, and then to stop convulsions. Specific cardiac resuscitation remains controversial because it is based principally on experimental results. We demonstrated that the combination of clonidine and dobutamine is efficient to reverse both haemodynamic and electrophysiologic impairments induced by a large dose of bupivacaine in anesthetized dogs. Whatever the efficiency of specific resuscitation, it must be emphasized that prevention of toxic accident must always include: the best choice of local anesthetic drug (e.g.: lidocaine+alpha-2 agonist vs bupivacaine), test dose, aspiration and slow administration. Finally, the monitoring of regional anaesthesia must be similar to that in use for general anaesthesia and drugs and devices for resuscitation must be ready. PMID:8287299

    Adrenal gland surgery needs a multidisciplinary team including endocrinologist, radiologist, anesthesiologist, and surgeon. The indications for adrenal gland surgery include hormonal secreting and non-hormonal secreting tumors. Adrenal hormonal secreting tumors present to the anesthesiologist unique challenges requiring good preoperative evaluation, perioperative hemodynamic control, corrections of all electrolytes and metabolic abnormalities, a detailed and careful anesthetic strategy, overall knowledge about the specific diseases, control and maintaining of postoperative adrenal function, and finally a good collaboration with other involved colleagues. This review will focus on the endocrine issues, as well as on the above-mentioned aspects of anesthetic management during hormone secreting adrenal gland tumor resection. PMID:25368694

    Congenital abnormalities of the large airways are uncommon, but may occasionally pose significant difficulties for anesthesiologists. The tracheal bronchus is an anatomical variant in which an accessory bronchus originates directly from the trachea rather than distal to the carina, as a takeoff from the right mainstem bronchus. Anesthesiologists should be aware of this uncommon anomaly, its different variants, and its management in order to successfully establish one lung ventilation (OLV) for surgical isolation. In this article, we report the challenges encountered in establishing OLV in a patient with a previously undiagnosed aberrant right upper lobe bronchus arising directly from the trachea.

    Antiphospholipid antibody syndrome (APLAS) characterises a clinical condition of arterial and venous thrombosis associated with phospholipids directed antibodies. APLAS occurs in 2% of the general population. However, one study demonstrated that 7.1% of hospitalised patients were tested positive for at least one of the three anticardiolipin antibody idiotype. Antiphospholipid antibodies often inhibit phospholipids dependent coagulation in vitro and interfere with laboratory testing of hemostasis. Therefore, the management of anticoagulation during cardiopulmonary bypass can be quite challenging in these patients. Here, we present a case of right atrial mass removal and pulmonary thrombectomy in a patient of APLAS. PMID:20075534

    Ultrashort barbiturates are not ideal injectable anesthetic agents, and new agents continue to be released as investigators pursue the goal of finding a more ideal agent. Of the new injectable agents discussed, propofol seems to be the most promising drug. Propofol should find a place in veterinary practice as an outpatient anesthetic agent because it has a rapid, smooth, and complete recovery even after repeated or continuous administration. Midazolam does not induce anesthesia in healthy, small animals and, as such, can only be used in combination with other injectable agents, such as ketamine or the thiobarbiturates. In our practice, Telazol has found a place in the anesthetic management of feral cats and aggressive dogs, where it is used for heavy sedation or to induce anesthesia. The role of flumazenil, as a reversal agent, in veterinary practice remains to be determined; however, the role in small domestic animals is unlikely to be significant. PMID:1585555

    A 2-year-and-4-month-old female infant, 12 kg in weight and 90 cm in height fell off from a table, which was about 1 m height with a toothbrush in her mouth without her parents noticing. Urgent CT scan showed that it penetrated the left side of her oropharyngeal wall to the bifurcation of her right carotid artery. According to the initial assessment, carotid artery seemed intact and there seemed to be no sign of CNS involvement. She underwent general anesthesia for further investigation and operation. We could detect vocal code with ease by inserting Glidescope between her tongue and the toothbrush. After the intubation, we administered fentanyl 25 μg rocuronium 15 mg and sevoflulane 3-5% to her, and then she underwent arteriography. The neurosurgeon found no sign of major arterial injury nor traumatic aneurysm nor CNS involvement. She went to the ICU intubated after the removal of the toothbrush. She was extubated 5 days after operation. One of the benefits of the Glidescope is that we can share the visual image, and we chose it this time. When we expect a difficult airway during management for oropharyngeal trauma, we have to consider the way to manage the airway. PMID:27188104

    Nitrous oxide is the most commonly used inhalation anesthetic in dentistry and is commonly used in emergency centers and ambulatory surgery centers as well. When used alone, it is incapable of producing general anesthesia reliably, but it may be combined with other inhalation and/or intravenous agents in deep sedative/general anesthestic techniques. However, as a single agent, it has impressive safety and is excellent for providing minimal and moderate sedation for apprehensive dental patients. To gain a full appreciation of the pharmacology, physiologic influences, and proper use of nitrous oxide, one must compare it with other inhalation anesthetics. The purpose of this CE article is to provide an overview of inhalation anesthetics in general and to address nitrous oxide more specifically in comparison. PMID:19108597

A five-year-old child, affected by a rare congenital disease (Van Maldergem Syndrome), suffered from conductive hearing loss. Conventional skin-drive bone-conduction device, attached with a steel spring headband, has been applied but auditory restoration was not optimal. The decision made was to position Vibrant Soundbridge, a middle ear implant, with an original surgical application due to hypoplasia of the tympanic cavity. Intubation procedure was complicated due to child craniofacial deformities. Postoperative hearing rehabilitation involved a multidisciplinary team, showing improved social skills and language development. PMID:26491591

    An extensive literature review was undertaken to evaluate the best anesthetic practice for carotid endarterectomy surgery. Two anesthetic techniques were evaluated: general anesthetic with an endotracheal tube and regional anesthetic block. Three variables were reviewed with respect to significant clinical outcomes based on anesthetic technique. Relevant literature was obtained through multiple sources that included professional journals, a professional website, and textbooks. According to the literature, there is an advantage to performing regional anesthesia with respect to cost and neurologic status. Information analyzed was inconclusive with respect to hemodynamic stability and anesthetic technique. We conclude that regional anesthesia may have some slight advantages; however, more investigation is warranted. PMID:17591300

    The ultrasound guidance in regional anesthesia ensures the visualization of needle placement and the spread of Local Anesthetics. Over the past few years there was a substantial interest in determining the Minimum Effective Anesthetic Volume necessary to accomplish surgical anesthesia. The precise and real-time visualization of Local Anesthetics spread under ultrasound guidance block may represent the best requisite for reducing Local Anesthetics dose and Local Anesthetics-related effects. We will report a series of studies that have demonstrated the efficacy of ultrasound guidance blocks to reduce Local Anesthetics and obtain surgical anesthesia as compared to block performed under blind or electrical nerve stimulation technique. Unfortunately, the results of studies are widely divergent and not seem to indicate a dose considered effective, for each block, in a definitive way; but it is true that, through the use of ultrasound guidance, it is possible to reduce the dose of anesthetic in the performance of anesthetic blocks.

    Epidermolysis bullosa is a group of inherited rare skin disease, characterized by bullae formation in the skin or mucous membranes. The fundamental abnormality is collagen degeneration leads to splitting of various epidermal layers. Dystrophic epidermolysis bullosa (DEB) is one of the major forms of epidermolysis bullosa. These patients often admitted to the hospital for corrective surgeries, change of dressing, contracture release, and skin grafting. Anesthetic management of these cases is always a challenge. We are reporting a case of 5-year-old boy diagnosed as a case of DEB scheduled for upper lip contracture release, skin grafting and debridement of nonhealing scars under anesthesia. In this case, we have focused mainly on the anesthetic management, preparation of the monitoring, transportation, difficulties in establishing the venous accesses, and airway management.

    2011-01-01

    Local anesthesia forms the foundation of pain control techniques in clinical dentistry. Within the rich local anesthetic drugs available in dentistry for the prevention and management of pain 4% articaine solutions achieve highest level of anesthetic potency and lowest systemic toxicity in all clinical situations, prior to its superlative physicochemical characteristics and the pharmacological profile. These are - low lipid solubility, high plasma protein binding rate, fast metabolization, fast elimination half time; low blood level. Articaine inactivates in both ways: in the liver and the blood serum. It has good spreading through tissues. Thus, articaine seems to be the local anesthetic of first choice in tissues with suppurative inflammation, for adults, children (over 4), elderly, pregnant women, breastfeeding women, patients suffering from hepatic disorders and renal function impairment. In Articaine solutions (1: 200,000) epinephrine is in low concentration, thus in patients at high risk adverse responses are maximally decreased. In these patients articaine should be used with careful consideration of risk/benefit ratio. Articaine solutions must not be used in persons who are allergic or hypersensitive to sulphite, due to content of Sodium metabisulfite as vasoconstrictor's antioxidant in it. Incidence of serious adverse effects related to dental anesthesia with articaine is very low. Toxic reactions are usually due to an inadvertent intravascular injection or use of excessive dose. To avoid overdoses maximum recommendation dose (MRD) must not be exceeded and aspiration test always performed prior all LA injections. In these article we introduce new graphs providing a quick and effect way to determine maximum LA dose. If the overdose reactions develop, adherence to the basic step of emergency management with end to a successful outcome in virtually all cases. PMID:21346262

    Anesthesiologists should fully inform patients of the possible complications from anesthesia. For rapport with the patient, with whom they usually have no acquaintance until a day or so before an operative procedure, the anesthesiologist should enlist the help of the internist or surgeon who already has established an atmosphere of trust. The extent of morbidity and minor complications from anesthesia has not been adequately recorded. One out of every 1,000 to 2,000 anesthetized patients dies of complications primarily due to or contributed to by anesthesia. Leading causes of death vary from study to study and from year to year.

    This paper discusses human spaceflight fault management operations. Fault detection and response capabilities available in current US human spaceflight programs Space Shuttle and International Space Station are described while emphasizing system design impacts on operational techniques and constraints. Preflight and inflight processes along with products used to anticipate, mitigate and respond to failures are introduced. Examples of operational products used to support failure responses are presented. Possible improvements in the state of the art, as well as prioritization and success criteria for their implementation are proposed. This paper describes how the architecture of a command and control system impacts operations in areas such as the required fault response times, automated vs. manual fault responses, use of workarounds, etc. The architecture includes the use of redundancy at the system and software function level, software capabilities, use of intelligent or autonomous systems, number and severity of software defects, etc. This in turn drives which Caution and Warning (C&W) events should be annunciated, C&W event classification, operator display designs, crew training, flight control team training, and procedure development. Other factors impacting operations are the complexity of a system, skills needed to understand and operate a system, and the use of commonality vs. optimized solutions for software and responses. Fault detection, annunciation, safing responses, and recovery capabilities are explored using real examples to uncover underlying philosophies and constraints. These factors directly impact operations in that the crew and flight control team need to understand what happened, why it happened, what the system is doing, and what, if any, corrective actions they need to perform. If a fault results in multiple C&W events, or if several faults occur simultaneously, the root cause(s) of the fault(s), as well as their vehicle-wide impacts, must be

    Taking EMLA cream and Penles tape 18 mg as examples, this article describes the conditions for skin penetration of topical anesthetics, with their onset time of action, duration of effect and a precautions for their use. EMLA cream is a unique cream for topical anesthesia which is the eutectic mixture of lidocaine and propitocaine to increase skin penetration. The safety study demonstrated that blood concentrations of active ingredients of EMLA cream were below toxic levels. EMLA cream, with confirmed high skin penetrability and safety, should be used for pain reduction of various treatments for many diseases. Here in Japan, EMLA cream has indications not only for pain reduction of skin laser therapy but also for reduction of needle puncture pain. This means the use of topical anesthesia would be expanded to wider ranges of treatments. PMID:26689066

    Management of hidradenitis suppurativa (HS) of the axilla which is nonresponding to conservative management presents a significant therapeutic challenge. Most surgical treatment options are associated with significant morbidities and prolonged hospital stay. We present a technique of management of HS using setons which is simple and allows the ongoing treatment to be done on an outpatient basis. Given the fact that HS is a chronic relapsing condition each recurrence may again be managed using this technique. This will allow the patients to manage their recurrences with minimal impact on their activities of daily living. PMID:26301111

    The management and control of a representative, highly integrated high-technology project, in the X-29A aircraft flight test project is addressed. The X-29A research aircraft required the development and integration of eight distinct technologies in one aircraft. The project management system developed for the X-29A flight test program focuses on the dynamic interactions and the the intercommunication among components of the system. The insights gained from the new conceptual framework permitted subordination of departments to more functional units of decisionmaking, information processing, and communication networks. These processes were used to develop a project management system for the X-29A around the information flows that minimized the effects inherent in sampled-data systems and exploited the closed-loop multivariable nature of highly integrated projects.

    Purpose Endophthalmitis is a rare complication of intravitreal injection (IVI). It is recommended that povidone-iodine be the last agent applied before IVI. Patients have reported povidone-iodine application to be the most bothersome part of IVIs. Topical anesthetics have been demonstrated to have antibacterial effects. This study compared the minimum inhibitory concentration (MIC) of topical anesthetic eye drops (proparacaine 0.5%, tetracaine 0.5%, lidocaine 2.0%) and the antiseptic, 5.0% povidone-iodine, against two organisms causing endophthalmitis after IVI. Methods Minimum inhibitory concentration values of topical anesthetics, povidone-iodine, preservative benzalkonium chloride (0.01%), and saline control were determined using five isolates of each Staphylococcus epidermidis and viridans group Streptococcus species (VGS). A broth microdilution technique was used with serial dilutions. Results Lidocaine (8.53 × 10−5mol/mL) had MICs of 4.27 to 8.53 × 10−5 mol/mL, and tetracaine (1.89 × 10−5 mol/mL) had MICs of 9.45 × 10−6 mol/mL for all isolates. Proparacaine (1.7 × 10−5 mol/mL) had MICs of 1.32 to 5.3 × 10−7 and 4.25 × 10−6 mol/mL for S. epidermidis and VGS, respectively). Benzalkonium chloride (3.52 × 10−7 mol/mL) had MICs of 1.86 × 10−9 to 1.1 × 10−8 and 4.40 × 10−8 mol/mL for S. epidermidis and VGS, respectively. Povidone-iodine (1.37 × 10−4 mol/mL) had MICs of 2.14 to 4.28 × 10−6 and 8.56 × 10−6 mol/mL for S. epidermidis and VGS, respectively. Conclusion Proparacaine was the anesthetic with the lowest MICs, lower than that of povidone-iodine. Benzalkonium chloride had lower MICs than proparacaine. All tested anesthetics and povidone-iodine inhibited growth of S. epidermidis and VGS at commercially available concentrations. Translational Relevance For certain patients, it could be possible to use topical anesthetic after povidone-iodine for comfort without inhibiting and perhaps contributing additional antimicrobial

    2013-12-01

    The psychedelic experience has been reported since antiquity, but there is relatively little known about the underlying neural mechanisms. A recent neuroimaging study on psilocybin revealed a pattern of decreased cerebral blood flow and functional disconnections that is surprisingly similar to that caused by various anesthetics. In this article, the authors review historical examples of psychedelic experiences induced by general anesthetics and then contrast the mechanisms by which these two drug classes generate altered states of consciousness.

    2016-08-01

    Over the past 40 years, the success of organ transplantation has increased such that female solid organ transplant recipients are able to conceive and carry pregnancies successfully to term. Anesthesiologists are faced with the challenge of providing anesthesia care to these high-risk obstetric patients in the peripartum period. Anesthetic considerations include the effects of the physiologic changes of pregnancy on the transplanted organ, graft function in the peripartum period, and the maternal side effects and drug interactions of immunosuppressive agents. These women are at an increased risk of comorbidities and obstetric complications. Anesthetic management should consider the important task of protecting graft function. Optimal care of a woman with a transplanted solid organ involves management by a multidisciplinary team. In this focused review article, we review the anesthetic management of pregnant patients with solid organ transplants of the kidney, liver, heart, or lung. PMID:27285002

    OBJECTIVE: To determine if topical administration of local anesthesia, applied to fresh skin-harvest sites, reduces pain and analgesic requirements after surgery. SUMMARY BACKGROUND DATA: Nonopioid treatments for pain after therapeutic procedures on patients with burns have become popular because of the side effects associated with narcotics. The topical administration of local anesthesia originally offered little advantage because of poor epidermal penetration. METHODS: This study compares 2% lidocaine with 0.5% bupivacaine or saline, topically applied after skin harvest, to determine what effect this may have on pain and narcotic use. Sixty patients with partial- or full-thickness burns to approximately 10% to 15% of their body were randomly divided into three groups: group 1 received normal saline, group 2 had 0.5% bupivacaine, and group 3 had 2% lidocaine sprayed onto areas immediately after skin harvest. Blood samples were subsequently obtained to measure concentrations of the local anesthetic. Hemodynamic variables after surgery, wake-up times, emetic symptoms, pain, and narcotic use were compared. RESULTS: Higher heart rates were noted in the placebo group than in those receiving lidocaine or bupivacaine. No differences were noted in recovery from anesthesia or emetic symptoms. Pain scores were lower and 24-hour narcotic use was less in patients who received lidocaine. Plasma lidocaine levels were greater than bupivacaine at all time points measured. CONCLUSIONS: Topical lidocaine applied to skin-harvest sites produced an analgesic effect that reduced narcotic requirements compared with patients who received bupivacaine or placebo. Local anesthetic solutions aerosolized onto skin-harvest sites did not affect healing or produce toxic blood concentrations. PMID:9923808

    Background: Keyhole craniotomies are increasingly being used for lesions of the skull base. Here we review our recent experience with these approaches for resection of intracranial meningiomas. Methods: Clinical and operative data were gathered on all patients treated with keyhole approaches by the senior author from January 2012 to June 2013. Thirty-one meningiomas were resected in 27 patients, including 9 supratentorial, 5 anterior fossa, 7 middle fossa, 6 posterior fossa, and 4 complex skull base tumors. Twenty-nine tumors were WHO Grade I, and 2 were Grade II.  Results: The mean operative time was 8 hours, 22 minutes (range, 2:55-16:14) for skull-base tumors, and 4 hours, 27 minutes (range, 1:45-7:13) for supratentorial tumors. Simpson Resection grades were as follows: Grade I = 8, II = 8, III = 1, IV = 15, V = 0. The median postoperative hospital stay was 4 days (range, 1-20 days). In the 9 patients presenting with some degree of visual loss, 7 saw improvement or complete resolution. In the 6 patients presenting with cranial nerve palsies, 4 experienced improvement or resolution of the deficit postoperatively. Four patients experienced new neurologic deficits, all of which were improved or resolved at the time of the last follow-up. Technical aspects and surgical nuances of these approaches for management of intracranial meningiomas are discussed.  Conclusions: With careful preoperative evaluation, keyhole approaches can be utilized singly or in combination to manage meningiomas in a wide variety of locations with satisfactory results.

    The laser Doppler flowmetry technique has recently been used to report a significant transient increase of the cutaneous blood flow signal when a local non-noxious pressure is applied progressively on the skin (11.1 Pa/s). The present work analyses the dynamic characteristics of this vasodilatory reflex response on anaesthetised rats. A de-noising algorithm using wavelets is proposed to obtain accurate values of these dynamic characteristics. The blood flow peak and the time to reach this peak are computed on the de-noised recordings. The results show that the mean time to reach the peak of perfusion is 85.3 s (time t = 0 at the beginning of the pressure application). The mean peak value is 188.3 arbitrary units (a.u.), whereas the mean value of the perfusion before the pressure application is 113.4 a.u. The mean minimum value obtained at the end of the experiment is 60.7 a.u. This latter value is, on the average, reached 841.3 s after the beginning of the pressure application. The comparison of the dynamic characteristics, computed with the de-noising algorithm on signals obtained in other situations, will give a better understanding on some cutaneous lesions such as those present on diabetic people.

    The prime NDT method selected for characterization of the waste is real-time x-radiography (RTR). An RTR system specifically designed for the TRU waste inspection is currently being used to develop the best techniques for waste certification. It is based on a standard 420 kV constant potential x-ray machine with a rare-earth fluorescing screen (gadolinium oxysulfide) functioning as an image converter. The low-light-level image produced on the screen is picked up by a CCTV camera with an image intensifier coupled to a plumbicon imaging tube. The system was designed for automated waste container handling and translation. Image analysis is not currently automated, although the CCTV image is digitized to allow signal averaging and edge enhancement through digital filtering. The digitized image is available through an IEEE 488 I/O port for more sophisticated computerized analysis.

    2016-05-01

    Ureteropelvic junction obstruction (UPJO) is a common congenital abnormality that often presents in adulthood. Open dismembered pyeloplasty was considered the gold standard for the management of this condition; however, recent advancements in laparoscopic and robotic surgery have dramatically shifted the landscape to more minimally invasive techniques. A literature search of ureteropelvic junction obstruction, pyeloplasty, endopyelotomy, laparoscopic pyeloplasty, robotic pyeloplasty, and microlaparoscopic pyeloplasty was performed. A focus was placed on literature published since 2013. Minimally invasive laparoscopic and robotic techniques have become the gold standard for the management of UPJO. With the rise of robotic pyeloplasty, open repairs are becoming less frequent, while endoscopic treatments have remained stable. Minimally invasive (robotic) techniques have become the gold standard for the management of UPJO. Newer, even less-invasive techniques are also showing promise, but technical challenges still exist.

    To minimize injection anxiety and discomfort, the podiatric surgeon can choose from a variety of topical anesthetics. Available modalities include skin refrigerants (also referred to as vapocoolants), needleless injection systems, iontophoresis, and eutectic mixtures of topical anesthetic cream such as EMLA Cream. Many of the vapocoolants contain chlorofluorocarbons, which are known to damage the ozone layer, a stratospheric layer that filters out harmful ultraviolet B radiation. In accordance with the 1992 Montreal Protocol, which banned the manufacture of certain chlorofluorocarbon compounds, many commonly used vapocoolants will no longer be available. Some newly marketed vapocoolants produce extremely cold temperatures, limiting their use. This article discusses the properties of various vapocoolants and other topical anesthetics and compares their effectiveness in patient trials. PMID:9503770

    Study Design Randomized controlled trial. Objective Adolescent idiopathic scoliosis (AIS) is a common spinal deformity that affects every population. In severe deformity, surgical intervention is performed. Autogenous iliac crest bone graft (ICBG) harvesting remains a common procedure worldwide for scoliosis surgery. Postoperative pain at the ICBG donor site is a major concern in patients undergoing spine surgery that affects postoperative functional outcome and consumes health care resources. Previous studies have noted a decrease in pain and postoperative analgesic use with the application of continuous infusion of anesthetic at the ICBG site in comparison with placebo. However, there is lack of evidence addressing the efficacy of continuous anesthetic infusion at the ICBG site in young patients and in particular those with spinal deformity, such as AIS. As such, this parallel, double-blinded, randomized controlled trial addressed the pain management efficacy of continuous anesthetic infusion versus saline at the ICBG site in patients with AIS during the immediate postoperative period. Methods Participants were randomized into two groups. Group A (control subjects) received 3 mL per hour of saline locally at the ICBG site, and group B (treatment subjects) received a constant rate of infusion of 3 mL per hour of 0.25% levobupivacaine. Both groups received their postoperative intervention for 47 hours. All subjects and outcome assessors were blinded to the type of intervention. Utilizing the visual analog pain scale, pain was assessed at the primary spine surgical site, ICBG site, and contralateral ICBG site. Overall physical pain was assessed by the McGill Pain Questionnaire. The degree of analgesic use and complications were also evaluated. All outcomes were assessed up until the fourth day of the patients' hospitalization following surgery. Results Twelve subjects were recruited (five in group A; seven in group B). No difference was noted at baseline

  11. Anesthetic considerations in orthopedic patients with or without trauma.

    Chohan, Amandeep S

    2010-05-01

    Anesthetic management of orthopedic patients could vary from normal routine management to more challenging critical management depending on the state in which the patient is presented. Multimodal pain management strategies incorporating opioids, which are the mainstay drugs for pain management, along with adjunctive drugs like local anesthetics (eg, lidocaine), dissociative anesthetics (eg, ketamine), and alpha-2 agonists (eg, dexmedetomidine), could improve overall patient comfort and help prevent establishment of chronic pain pathways. Also, use of local nerve blocks can prevent nociception right at the point of origin. Orthopedic patients with multiple organ traumas like head injuries, spinal injuries, pulmonary fat embolism, compartment syndrome, or thoracic injuries are high-risk patients in which any life-threatening organ pathology should be addressed before the patient is put under general anesthesia. Interactions of various drugs like antibiotics and neuromuscular blocking agents used in the perioperative period in orthopedic patients should warrant a careful consideration with respect to their interactions with each other and other anesthetic drugs used.

    With growing use of internet and exponential growth in amount of data to be stored and processed (known as ``big data''), the size of data centers has greatly increased. This, however, has resulted in significant increase in the power consumption of the data centers. For this reason, managing power consumption of data centers has become essential. In this paper, we highlight the need of achieving energy efficiency in data centers and survey several recent architectural techniques designed for power management of data centers. We also present a classification of these techniques based on their characteristics. This paper aims to provide insights into the techniques for improving energy efficiency of data centers and encourage the designers to invent novel solutions for managing the large power dissipation of data centers.

  13. Hoshin Kanri: a technique for strategic quality management.

    PubMed

    Tennant, C; Roberts, P A

    2000-01-01

    This paper describes a technique for Strategic Quality Management (SQM), known as Hoshin Kanri, which has been operated as a management system in many Japanese companies since the 1960s. It represents a core aspect of Japanese companies' management systems, and is stated as: the means by which the overall control system and Total Quality Management (TQM) are deployed. Hoshin Kanri is not particularly unique in its concept of establishing and tracking individual goals and objectives, but the manner in which the objectives and the means to achieve them are developed and deployed is. The problem with applying the concept of Strategic Quality Management (SQM) using Hoshin Kanri, is that it can tend to challenge the traditional authoritarian strategic planning models, which have become the paradigms of modern business. Yet Hoshin Kanri provides an appropriate tool for declaration of the strategic vision for the business while integrating goals and targets in a single holistic model. There have been various adaptations of Hoshin Kanri to align the technique to Western thinking and management approaches, yet outside Japan its significance has gone largely unreported. It is proposed that Hoshin Kanri is an effective methodology for SQM, which has a number of benefits over the more conventional planning techniques. The benefits of Hoshin Kanri as a tool for Strategic Quality Management (SQM) compared to conventional planning systems include: integration of strategic objectives with tactical daily management, the application of the plan-do-check-act cycle to business process management, parallel planning and execution methodology, company wide approach, improvements in communication, increased consensus and buy-in to goal setting, and cross-functional-management integration.

    2014-01-01

    Background Continuous content management of health information portals is a feature vital for its sustainability and widespread acceptance. Knowledge and experience of a domain expert is essential for content management in the health domain. The rate of generation of online health resources is exponential and thereby manual examination for relevance to a specific topic and audience is a formidable challenge for domain experts. Intelligent content discovery for effective content management is a less researched topic. An existing expert-endorsed content repository can provide the necessary leverage to automatically identify relevant resources and evaluate qualitative metrics. Objective This paper reports on the design research towards an intelligent technique for automated content discovery and ranking for health information portals. The proposed technique aims to improve efficiency of the current mostly manual process of portal content management by utilising an existing expert-endorsed content repository as a supporting base and a benchmark to evaluate the suitability of new content Methods A model for content management was established based on a field study of potential users. The proposed technique is integral to this content management model and executes in several phases (ie, query construction, content search, text analytics and fuzzy multi-criteria ranking). The construction of multi-dimensional search queries with input from Wordnet, the use of multi-word and single-word terms as representative semantics for text analytics and the use of fuzzy multi-criteria ranking for subjective evaluation of quality metrics are original contributions reported in this paper. Results The feasibility of the proposed technique was examined with experiments conducted on an actual health information portal, the BCKOnline portal. Both intermediary and final results generated by the technique are presented in the paper and these help to establish benefits of the technique and

    2013-01-01

    Robotic-assisted surgery has evolved over the past two decades with constantly improving technology, assisting surgeons in multiple subspecialty disciplines. The surgical requirements of lithotomy and steep Trendelenburg positions, along with the creation of a pneumoperitoneum and limited access to the patient, all present anesthetic management challenges in urologic surgery. Patient positioning requirements can cause significant physiologic effects and may result in many complications. Good communication among team members and knowledge of the nuances of robotic surgery have the potential to improve patient outcomes, increase efficiency, and reduce surgical and anesthetic complications.

    Local anesthetics block the transmission of painful stimuli to the brain by acting on ion channels of nociceptor fibers, and find application in the management of acute and chronic pain. Despite the key role they play in modern medicine, their cardio and neurotoxicity (together with their short half-life) stress the need for developing implantable devices for tailored local drug release, with the aim of counterbalancing their side effects and prolonging their pharmacological activity. This review discusses the evolution of the physical forms of local anesthetic delivery systems during the past decades. Depending on the use of different biocompatible materials (degradable polyesters, thermosensitive hydrogels, and liposomes and hydrogels from natural polymers) and manufacturing processes, these systems can be classified as films or micro- or nanostructured devices. We analyze and summarize the production techniques according to this classification, focusing on their relative advantages and disadvantages. The most relevant trend reported in this work highlights the effort of moving from microstructured to nanostructured systems, with the aim of reaching a scale comparable to the biological environment. Improved intracellular penetration compared to microstructured systems, indeed, provides specific drug absorption into the targeted tissue and can lead to an enhancement of its bioavailability and retention time. Nanostructured systems are realized by the modification of existing manufacturing processes (interfacial deposition and nanoprecipitation for degradable polyester particles and high- or low-temperature homogenization for liposomes) or development of novel strategies (electrospun matrices and nanogels). The high surface-to-volume ratio that characterizes nanostructured devices often leads to a burst drug release. This drawback needs to be addressed to fully exploit the advantage of the interaction between the target tissues and the drug: possible strategies

Nanostructured systems are realized by the modification of existing manufacturing processes (interfacial deposition and nanoprecipitation for degradable polyester particles and high- or low-temperature homogenization for liposomes) or development of novel strategies (electrospun matrices and nanogels). The high surface-to-volume ratio that characterizes nanostructured devices often leads to a burst drug release. This drawback needs to be addressed to fully exploit the advantage of the interaction between the target tissues and the drug: possible strategies

    General anesthetic drugs interact with many receptors in the nervous system, but only a handful of these interactions are critical for producing anesthesia. Over the last 20 years, neuropharmacologists have revealed that one of the most important target sites for general anesthetics is the GABAA receptor. In this review we will discuss what is known about anesthetic – GABAA receptor interactions. PMID:20808541

    The practice of anesthetic premedication embarked upon soon after ether and chloroform were introduced as general anesthetics in the middle of the 19(th) century. By applying opioids and anticholinergics before surgery, the surgical patients could achieve a less anxious state, and more importantly, they would acquire a smoother course during the tedious and dangerous induction stage. Premedication with opioids and anticholinergics was not a routine practice in the 20(th) century when intravenous anesthetics were primarily used as induction agents that significantly shorten the induction time. The current practice of anesthetic premedication has evolved into a generalized scheme that incorporates several aspects of patient care: decreasing preoperative anxiety, dampening intraoperative noxious stimulus and its associated neuroendocrinological changes, and minimizing postoperative adverse effects of anesthesia and surgery. Rational use of premedication in modern anesthesia practice should be justified by individual needs, the types of surgery, and the anesthetic agents and techniques used. In this article, we will provide our readers with updated information about premedication of surgical patients with a focus on the recent application of second generation serotonin type 3 antagonist, antidepressants, and anticonvulsants.

    The anesthesia has been improved all over the years. However, it can have impact on health, in both patients and animals anesthetized, as well as professionals exposed to inhaled anesthetics. There is continuing effort to understand the possible effects of anesthetics at molecular levels. Knowing the effects of anesthetic agents on genetic material could be a valuable basic support to better understand the possible mechanisms of these agents. Thus, the purpose of this review is to provide an overview on the genotoxic potential, evaluated in animal models, of many anesthetics that have already been used and those currently used in anesthesia.

    At the request of the Department of Energy (DOE) Office of Science (SC), Lawrence Livermore National Laboratory (LLNL) hosted a two-day Risk Management Techniques and Practice (RMTAP) workshop held September 18-19 at the Hotel Nikko in San Francisco. The purpose of the workshop, which was sponsored by the SC/Advanced Scientific Computing Research (ASCR) program and the National Nuclear Security Administration (NNSA)/Advanced Simulation and Computing (ASC) program, was to assess current and emerging techniques, practices, and lessons learned for effectively identifying, understanding, managing, and mitigating the risks associated with acquiring leading-edge computing systems at high-performance computing centers (HPCCs). Representatives from fifteen high-performance computing (HPC) organizations, four HPC vendor partners, and three government agencies attended the workshop. The overall workshop findings were: (1) Standard risk management techniques and tools are in the aggregate applicable to projects at HPCCs and are commonly employed by the HPC community; (2) HPC projects have characteristics that necessitate a tailoring of the standard risk management practices; (3) All HPCC acquisition projects can benefit by employing risk management, but the specific choice of risk management processes and tools is less important to the success of the project; (4) The special relationship between the HPCCs and HPC vendors must be reflected in the risk management strategy; (5) Best practices findings include developing a prioritized risk register with special attention to the top risks, establishing a practice of regular meetings and status updates with the platform partner, supporting regular and open reviews that engage the interests and expertise of a wide range of staff and stakeholders, and documenting and sharing the acquisition/build/deployment experience; and (6) Top risk categories include system scaling issues, request for proposal/contract and acceptance testing, and

    Background: Surgical reconstruction of segmental skeletal defects represents a true challenge for the orthopedic surgeons. Recently, Masquelet et al. described a two-stage technique for reconstruction of bone defects, known as the induced membrane technique. The aim of this study is to assess the results of the induced membrane technique in the management of segmental skeletal defects resulting from debridement of bone infection. Materials and Methods: Seventeen patients with segmental skeletal defects were treated in our institution by the induced membrane technique. The average age of the patients was 43 years (range 26- 58 years). The causes of the defects were infected gap nonunion in 12 cases and debridement of osteomyelitis in 5 cases. The defects were located in the tibia (n = 13) and the femur (n = 4). The mean defect was 7 cm (range 4 cm - 11 cm). All cases were treated by the induced membrane technique in two-stages. Results: Bone union happened in 14 patients. The limb length discrepancy did not exceed 2.5 cm in the healed cases. The mean time of healing was 10 months (range 6-19 months). The complications included nonunion of the graft in five cases, failure of graft maturation in two cases, reactivation of infection in two cases and refracture after removal of the frame in one case. These complications were managed during the course of treatment and they did not affect the final outcome in all patients except three. Conclusion: The induced membrane technique is a valid option for the management of segmental skeletal defects. It is a simple and straight forward procedure, but the time required for growth and maturation of the graft is relatively long. PMID:26806972

    Cultural resource management archaeology in the United States concerns compliance with legislation set in place to protect archaeological resources from the impact of modern activities. Traditionally, surface collection, shovel testing, test excavation, and mechanical stripping are used in these projects. These methods are expensive, time consuming, and may poorly represent the features within archaeological sites. The use of remote sensing techniques in cultural resource management archaeology may provide an answer to these problems. Near-surface geophysical techniques, including magnetometry, resistivity, electromagnetics, and ground penetrating radar, have proven to be particularly successful at efficiently locating archaeological features. Research has also indicated airborne and satellite remote sensing may hold some promise in the future for large-scale archaeological survey, although this is difficult in many areas of the world where ground cover reflect archaeological features in an indirect manner. A cost simulation of a hypothetical data recovery project on a large complex site in Mississippi is presented to illustrate the potential advantages of remote sensing in a cultural resource management setting. The results indicate these techniques can save a substantial amount of time and money for these projects.

    Satellite remote sensing and GIS have emerged as the most powerful tools for inventorying, monitoring and management of natural resources and environment. In the special context of wetland ecosystems, remotely sensed data from orbital platforms have been extensively used in India for the inventory, monitoring and preparation of action plans for conservation and management. First scientific inventory of wetlands in India was carried out in 1998 by Space Applications Centre (ISRO), Ahmedabad using indigenous IRS (Indian Remote Sensing Satellite) data of 1992-93 timeframe, which stimulated extensive use of geospatial techniques for wetland conservation and management. Subsequently, with advances in GIS, studies were carried out for development of Wetland Information System for a state (West Bengal) and for Loktak lake wetland (a Ramsar site) as a prelude to National Wetland Information System. Research has also been carried out for preparation of action plans especially for Ramsar sites in the country. In a novel research, use of the geospatial technology has also been demonstrated for biodiversity conservation using landscape ecological metrics. A country-wide estimate of emission of methane, a Green House Gas, from wetlands has also been made using MODIS data. Present article critically reviews the work carried out in India for wetland conservation and management using geospatial techniques. PMID:24486190

  10. Decline in the Development of New Anesthetics.

    The number of new anesthetics approved by the USA FDA over the past 30 years (1985-2014) is much smaller than during the preceding 30 years (1955-1984): four versus ten. Investigational anesthetics clinically tested since 1990 have been almost exclusively intravenous anesthetics (nine compounds), with only one now approved by the FDA. All nine agents represent modifications of anesthetics introduced approximately 40-50 years ago; none demonstrates a truly novel mechanism of action. The apparent drought of novel anesthetics is difficult to explain. While there may be multiple reasons, we believe that one is especially noteworthy: the dramatic improvement in anesthesia safety owing to the context in which anesthetics are administered, effectively decreasing the pressure to develop new drugs with better safety margins.
