Post-caesarean section infection is a cause of maternal morbidity and mortality. Administration of antibiotic prophylaxis is recommended for preventing infection after caesarean delivery. The route of administration of antibiotic prophylaxis should be effective, safe and convenient. Currently, there is a lack of synthesised evidence regarding the benefits and harms of different routes of antibiotic prophylaxis for preventing infection after caesarean section. The aim of this review was to assess the benefits and harms of different routes of prophylactic antibiotics given for preventing infectious morbidity in women undergoing caesarean section. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2016), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (6 January 2016) and reference lists of retrieved studies. We included randomised controlled trials (RCTs) comparing at least two alternative routes of antibiotic prophylaxis for caesarean section (both elective and emergency). Cross-over trials and quasi-RCTs were not eligible for inclusion. Two review authors independently assessed trials for inclusion, assessed the risk of bias and extracted data from the included studies. These steps were checked by a third review author. We included 10 studies (1354 women). The risk of bias was unclear or high in most of the included studies.All of the included trials involved women undergoing caesarean section whether elective or non-elective. Intravenous antibiotics versus antibiotic irrigation (nine studies, 1274 women) Nine studies (1274 women) compared the administration of intravenous antibiotics with antibiotic irrigation. There were no clear differences between groups in terms of this review's maternal primary outcomes: endometritis (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.70 to 1.29; eight studies (966 women) (low-quality evidence)); wound infection (RR 0.49, 95% CI 0.17 to 1.43; seven

The purpose of this Roy Adaptation Model-based study was to describe women's physical, emotional, functional and social adaptation; postpartum concerns; and learning needs during the first two weeks following caesarean birth and identify relevant nursing interventions. Studies of caesarean-delivered women indicated a trend toward normalisation of the caesarean birth experience. Escalating caesarean birth rates mandate continued study of contemporary caesarean-delivered women. Mixed methods (qualitative and quantitative) descriptive research design. Nursing students collected data from 233 culturally diverse caesarean-delivered women in urban areas of the Midwestern and Northeastern USA between 2002-2004. The focal stimulus was the planned or unplanned caesarean birth; contextual stimuli were cultural identity and parity. Adaptation was measured by open-ended interview questions, fixed choice questionnaires about postpartum concerns and learning needs and nurse assessment of post-discharge problems. Potential interventions were identified using the Omaha System Intervention Scheme. More positive than negative responses were reported for functional and social adaptation than for physical and emotional adaptation. Women with unplanned caesarean births and primiparous women reported less favourable adaptation than planned caesarean mothers and multiparas. Black women reported lower social adaptation, Hispanic women had more role function concerns and Black and Hispanic women had more learning needs than White women. Post-discharge nursing assessments revealed that actual problems accounted for 40% of identified actual or potential problems or needs. Health teaching was the most commonly recommended postpartum intervention strategy followed by case management, treatment and surveillance interventions. Caesarean-delivered women continue to experience some problems with adapting to childbirth. Recommended intervention strategies reflect the importance of health teaching

An overabundance of bacteria in the chronic wound plays a significant role in the decreased ability for primary closure. One means of decreasing the bioburden in a wound is to operatively debride the wound for wound bed optimization prior to application of other therapy, such as Negative Pressure Wound Therapy (NPWT). We undertook a prospective pilot study to assess the efficacy of wound bed preparation for a standard algorithm (sharp surgical debridement followed by NPWT) versus one employing sharp surgical debridement followed by Negative Pressure Wound Therapy with Instillation (NPWTi). Thirteen patients, corresponding to 16 chronic lower leg and foot wounds were taken to the operating room for debridement. The patients were sequentially enrolled in 2 treatment groups: the first receiving treatment with operative debridement followed by 1 week of NPWT with the instillation of quarter strength bleach solution; the other receiving a standard algorithm consisting of operative debridement and 1 week of NPWT. Quantitative cultures were taken pre-operatively after sterile preparation and draping of the wound site (POD # 0, pre-op), post-operatively once debridement was completed (POD # 0, post-op), and on post-operative day 7 after operative debridement (POD # 7, post-op). After operative debridement (post-operative day 0) there was a mean of 3 (±1) types of bacteria per wound. The mean CFU/gram tissue culture was statistically greater - 3.7 × 10(6) (±4 × 10(6)) in the NPWTi group, while in the standard group (NPWT) the mean was 1.8 × 10(6) (±2.36 × 10(6)) CFU/gram tissue culture (p = 0.016); at the end of therapy there was no statistical difference between the two groups (p = 0.44). Wounds treated with NPWTi had a mean of 2.6 × 10(5) (±3 × 10(5)) CFU/gram of tissue culture while wounds treated with NPWT had a mean of 2.79 × 10(6) (±3.18 × 10(6)) CFU/gram of tissue culture (p = 0.43).

Little evidence is available on complementary therapies for anxiety and pain relief after caesarean delivery. The purpose of this study was to evaluate the effects of foot massage post-operatively in patients after caesarean delivery. 70 patients were divided to the study or control group after cesarean delivery. Patients in the study group had foot massages for 20 min after surgery. All patients underwent heart rate variability analysis (HRV) and scored their anxiety; pain intensity was evaluated using an 11-point numerical rating scale (NRS). In the study group the HRV, as measured by the low frequency power (LF) value and the LF-to-high frequency power (LF/HF) ratio during Holter assessment, was significantly less after foot massage intervention, but was not changed in the control group. Moreover, the HF value significantly increased and the anxiety score significantly decreased after foot massage intervention, but not in the control group. The pain intensity score obtained 60 min after the massage was significantly lower in the study group than the control group, as were the vital signs (respiratory rate, and systolic and diastolic blood pressure). Post-operative massage intervention can reduce anxiety and pain in patients after caesarean delivery. © Georg Thieme Verlag KG Stuttgart · New York.

Fetal laceration is a recognized complication of caesarean delivery. The aim of this study was to investigate the incidence, type, location, risk factors and long-term consequences of accidental fetal incised wounds during caesarean delivery. During a five-year period, we observed 25 cases of fetal lacerations caused by the scalpel during hysterotomy. In 20 of these cases, we observed these lesions as consultants for the Neonatologic Care Unit; the other five cases came under our care after an insurance claim for damages against the gynaecologist. All the infants had a lesion located to the head. In only 5 of the 25 cases the lesion was reported in the operative summary, and only 16 of the 25 mothers had signed an informed consent before surgery. With regard to the 20 cases diagnosed at the Neonatologic Care Unit, the lesion was closed using single stitches in nine cases, and with biological glue in 11 cases. Concerning the five cases that underwent legal proceedings against the gynaecologist, a clinical examination was performed by an expert in Public Health and Social Security in collaboration with a paediatric surgeon to evaluate the degree of biological damage. In all five cases, the result of the legal challenge was monetary compensation for the physical and moral damage caused by the gynaecologists to the patients and their parents. Accidental fetal lesions may occur during caesarean delivery; the incidence is significantly higher during emergency caesarean delivery compared to elective procedures. Patients should sign an informed consent in which they should be informed about the risk of the occurrence of fetal lacerations during caesarean delivery in order to avoid legal complications. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The aim of this study is to determine the degree and nature of women's involvement in the decision to deliver by Caesarean section. A cross sectional descriptive multi-centre study on post partum women who were delivered by Caesarean section in the three study centres. The five most common indicators for Caesarean section include cephalo-pelvic disproportion, prolonged labour, malpresentation, pregnancy induced hypertension and ante partum haemorrhage, which accounted for 70% of the indications for Caesarean section. The commonest influence on respondents' decision to have Caesarean section was physician factors, followed by religious and cultural factors. Husbands influenced majority of the respondents during decision for Caesarean section. The respondents' agreement with decision for Caesarean section varied significantly as the number of previous Caesarean section, being highest among women with 4 previous Caesarean section. In conclusion, the majority of women were found to be involved in the decision to have Caesarean section, and the most influential factors on them during the decision process were physician factors and husband's presence. In this environment, the greater the number of previous Caesarean section a woman has had in the past the more likely would she accept Caesarean section in subsequent deliveries as a better option. There is need for further studies to determine the effect of socio-demographic factors on decision to have caesarean section as well as satisfaction of the outcome.

The CORONIS Trial. International study of caesarean section surgical techniques: a randomised fractional, factorial trial

PubMed Central

2007-01-01

Background Caesarean section is one of the most commonly performed operations on women throughout the world. Rates have increased in recent years – about 20–25% in many developed countries. Rates in other parts of the world vary widely. A variety of surgical techniques for all elements of the caesarean section operation are in use. Many have not yet been rigorously evaluated in randomised controlled trials, and it is not known whether any are associated with better outcomes for women and babies. Because huge numbers of women undergo caesarean section, even small differences in post-operative morbidity rates between techniques could translate into improved health for substantial numbers of women, and significant cost savings. Design CORONIS is a multicentre, fractional, factorial randomised controlled trial and will be conducted in centres in Argentina, Ghana, India, Kenya, Pakistan and Sudan. Women are eligible if they are undergoing their first or second caesarean section through a transverse abdominal incision. Five comparisons will be carried out in one trial, using a 2 × 2 × 2 × 2 × 2 fractional factorial design. This design has rarely been used, but is appropriate for the evaluation of several procedures which will be used together in clinical practice. The interventions are: • Blunt versus sharp abdominal entry • Exteriorisation of the uterus for repair versus intra-abdominal repair • Single versus double layer closure of the uterus • Closure versus non-closure of the peritoneum (pelvic and parietal) • Chromic catgut versus Polyglactin-910 for uterine repair The primary outcome is death or maternal infectious morbidity (one or more of the following: antibiotic use for maternal febrile morbidity during postnatal hospital stay, antibiotic use for endometritis, wound infection or peritonitis) or further operative procedures; or blood transfusion. The sample size required is 15,000 women in total; at least 7,586 women in each comparison

The aim of this article was to identify the literature that examined and explored physical and psychological morbidity and patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. A systematic review of the literature using the databases MEDLINE, CINAHL and EMBASE was undertaken. The papers were examined using title and abstract for relevance to the primary and secondary outcomes. The primary outcome of interest was family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. The search yielded 275 records after removing any duplicates; eight studies were considered eligible and were reviewed as full text. Following full review, none of the studies was included in this article. To conclude, there were no papers that investigated or examined the concept of resilience in relation to the management of acute post-surgical orthopaedic wounds. Four of the papers identified, following the review process, did discuss quality of life outcomes and how these may be improved following wound development; most papers focused on the management of chronic wounds. It is apparent from the review that there is no evidence currently available that explores patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. © 2013 The Authors.

Quality of obstetric care in the sparsely populated sub-arctic area of Norway 2009–2011

PubMed Central

2013-01-01

Background It is challenging to obtain high quality obstetric care in a sparsely populated area. In the subarctic region of Norway, significant distances, weather conditions and seasonable darkness have called for a decentralized care model. We aimed to explore the quality of this care. Methods A retrospective study employing data (2009–11) from the Medical Birth Registry of Norway was initiated. Northern Norwegian and Norwegian figures were compared. Midwife administered maternity units, departments at local and regional specialist hospitals were compared. National registry data on post-caesarean wound infection (2009–2010) was added. Quality of care was measured as rate of multiple pregnancies, caesarean section, post-caesarean wound infection, Apgar score <7, birth weight <2.5 kilos, perineal rupture, stillbirth, eclampsia, pregnancy induced diabetes and vacuum or forceps assisted delivery. There were 15,586 births in 15 delivery units. Results Multiple pregnancies were less common in northern Norway (1.3 vs. 1.7%) (P = 0.02). Less use of vacuum (6.6% vs. 8.3%) (P = 0.01) and forceps (0.9% vs 1.7%) (P < 0.01) assisted delivery was observed. There was no difference with regard to pregnancy induced diabetes, caesarean section, stillbirth, Apgar score < 7 and eclampsia. A significant difference in birth weight < 2.5 kilos (4.7% vs. 5.0%) (P < 0.04) and perineal rupture grade 3 and 4 (1.5% vs. 2.3%) (P < 0.02) were revealed. The post-caesarean wound infection rate was higher (10.5% vs. 7.4%) (P < 0.01). Conclusion Northern Norway had an obstetric care of good quality. Birth weight, multiple pregnancies and post-caesarean wound infection rates should be further elucidated. PMID:24034451

Vaginal birth after one previous lower segment caesarean section represents one of the most significant and challenging issues in obstetric practice. A 5-year retrospective study was carried out at the University of Benin Teaching Hospital between January 1999 and December 2003, to determine the incidence, the maternal and fetal outcome following vaginal delivery after one previous caesarean section with a view to evaluating its safety and efficacy. There were 5234 deliveries, with 395 cases of one previous caesarean section, giving an incidence of 7.5%. The incidences of emergency caesarean section, elective caesarean section and spontaneous vaginal delivery following trial of vaginal delivery were 34.7%, 9.4% and 48.1%, respectively. During the study period there were 1317 cases of caesarean section, giving an incidence of 25.2% caesarean section rate. The incidence of one previous section among all caesarean section births was 30%. The major morbidity following vaginal delivery was uterine rupture with an incidence of 1.5% and hysterectomy of 0.8%. Three of the uterine ruptures occurred before admission because the patients laboured at home. One maternal death occurred as a result of uterine rupture and postpartum haemorrhage, giving a maternal mortality ratio of 19/100,000 and a case fatality rate of 0.3%. The corrected perinatal mortality rate was 15.2/1000, mainly from obstructed labour, abruptio placenta and fetal distress. Both maternal and fetal mortalities from vaginal birth after one previous section were significantly less than the respective overall maternal and fetal mortality from the institution. The 1-minute apgar score of babies delivered by elective section was significantly (P < 0.001) higher than the apgar score of babies delivered by emergency section and vaginally. There was only one patient with wound dehiscence at elective section without associated perinatal death. Vaginal delivery following caesarean section is relatively safe. However

When a woman has had a previous caesarean birth and requires induction of labour in a subsequent pregnancy there are two options for her care, an elective repeat caesarean or planned induction of labour. While there are risks and benefits for both elective repeat caesarean birth and planned induction of labour, current sources of information are limited to non-randomised cohort studies. Studies designed in this way have significant potential for bias and consequently any conclusions based on these results are limited in their reliability and should be interpreted with caution. To assess, using the best available evidence, the benefits and harms of elective repeat caesarean section and planned induction of labour for women with a previous caesarean birth, who require induction of labour in a subsequent pregnancy. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (31 October 2014). Randomised controlled trials with reported data that compared outcomes in mothers and babies for women who planned an elective repeat caesarean section with outcomes in women who planned induction of labour, where a previous birth had been by caesarean. There was no data extraction performed. There were no randomised controlled trials identified. Both planned elective repeat caesarean section and planned induction of labour for women with a prior caesarean birth are associated with benefits and harms. Evidence for these care practices is drawn from non-randomised studies that are associated with potential bias. Any results and conclusions must therefore be interpreted with caution. Randomised controlled trials are required to provide the most reliable evidence regarding the benefits and harms of both planned elective repeat caesarean section and planned induction of labour for women with a previous caesarean birth.

We evaluated the efficacy of dexpanthenol in managing pediatric post-tonsillectomy pain and wound healing and sought to discover which of two surgical tonsillectomy techniques provides better healing and less postoperative pain. One hundred twenty patients who underwent tonsillectomy were equally randomized to thermal welding and cold dissection groups. Dexpanthenol pastilles were given to half of each group. Postoperative throat pain was determined with a visual analog scale on the 1st, 3th, 7th, and 14th days, and mucosal healing patterns were assessed on the 7th and 14th days. Regardless of surgical technique, post-tonsillectomy throat pain was significantly less in the dexpanthenol groups than in the placebo groups (p < 0.05), and tonsillar wound healing was significantly better in the dexpanthenol groups than in the placebo groups (p < 0.05). When a comparison was made with regard to surgical technique, wound healing was significantly better in the cold dissection group (p < 0.05), whereas postoperative throat pain was less in the thermal welding group (p < 0.05). Postoperative administration of dexpanthenol significantly accelerates the wound healing process and decreases tonsillectomy-related pain complaints.

We present the case of a 31-year-old woman with Ehler-Danlos syndrome (EDS) type 2. She had a previous caesarean section and went on to have an uncomplicated vaginal birth in her last pregnancy. To our knowledge, this is the first case of a successful vaginal birth after caesarean section in a patient with EDS. EDS is a multisystem disorder involving a genetic defect in collagen and connective-tissue synthesis and structure. It is a heterogeneous group of 11 different inherited disorders. Obstetric complications in these patients include miscarriages, stillbirths, premature rupture of the membranes, preterm labour, uterine prolapse, uterine rupture and severe postpartum haemorrhage. There has been much controversy over the appropriate mode of delivery. Abdominal deliveries are complicated by delayed wound healing and increased perioperative blood loss. Vaginal deliveries may be complicated by tissue friability causing extensive perineal tears, pelvic floor and bladder lesions. Our case highlights that in specific, controlled situations it is possible to have a vaginal delivery even after previous caesarean section in patients with EDS.

To quantify the association between maternal obesity and caesarean delivery, particularly caesarean delivery on maternal request (CDMR), a fast-growing component of caesarean delivery in many nations. We followed 1,019,576 nulliparous women registered in the Perinatal Healthcare Surveillance System during 1993-2010. Maternal body mass index (BMI, kg/m(2) ), before pregnancy or during early pregnancy, was classified as underweight (<18.5), normal (18.5 to <23; reference), overweight (23 to <27.5), or obese (≥27.5), consistent with World Health Organization guidelines for Asian people. The association between maternal obesity and overall caesarean and its subtypes was modelled using log-binomial regression. During the 18-year period, 404,971 (39.7%) caesareans and 93,927 (9.2%) CDMRs were identified. Maternal obesity was positively associated with overall caesarean and CDMR. Adjusted risk ratios for overall caesarean in the four ascending BMI categories were 0.96 [95% confidence interval (CI) 0.94, 0.97], 1.00 (Reference), 1.16 [95% CI 1.14, 1.18], 1.39 [95% CI 1.43, 1.54], and for CDMR were 0.95 [95% CI 0.94, 0.96], 1.00 (Reference), 1.20 [95% CI 1.18, 1.22], 1.48 [95% CI 1.433, 1.54]. Positive associations were consistently found in women residing in southern and northern provinces and in subgroups stratified by year of delivery, urban or rural residence, maternal age, education, level of delivering hospital, and birthweight. In a large Chinese cohort study, maternal obesity was associated with an increased risk of caesarean delivery and its subtypes, including CDMR. Given the rising global prevalence of obesity, and in view of the growth of CDMR, it seems likely that caesarean births will increase, unless there are changes in obstetrical practice. © 2015 John Wiley & Sons Ltd.

Post-operative analgesic effect of dexmedetomidine administration in wound infiltration for abdominal hysterectomy: A randomised control study

PubMed Central

Singh, Swati; Prasad, Chandrakant

2017-01-01

Background and Aims: Local infiltration of the surgical wound is one of the important components of multimodal analgesia for post-operative pain relief. This study determines the post-operative analgesic effect of addition of dexmedetomidine to bupivacaine for local infiltration of the surgical wound. Methods: Sixty women belonging to American Society of Anesthesiologists’ Grade 1 or 2 posted for abdominal hysterectomy were randomly allocated to Group I (control group) where patients received wound infiltration with 30 mL 0.25% bupivacaine at the end of surgery, or Group II, where patients received wound infiltration with 1.0 μg/kg dexmedetomidine diluted in 30 mL 0.25% bupivacaine. The primary objective of the study was to assess post-operative pain scores. Number of patients requiring rescue analgesia and total morphine consumption during 24 h after surgery were also recorded. Statistical significance for analgesic requirement was determined by one-way analysis of variance. Results: Pain scores were lower at rest for 12 h and on cough for 6 h in Group II (<0.01). All patients in Group I required supplemental morphine compared to only 3 patients in Group II (P < 0.003). Post-operative analgesia requirement was significantly less in patients receiving dexmedetomidine in wound infiltration compared to patients receiving bupivacaine alone (P < 0.001). Conclusions: Wound infiltration of dexmedetomidine with bupivacaine provides superior pain relief compared to bupivacaine alone. PMID:28655956

The rate of caesarean section deliveries has increased globally and mothers are faced with challenges of postoperative recovery and caring thereof. Midwives have a duty to assist these mothers to self-care. The objective was to explore and describe experiences of post-caesarean section delivered mothers of midwifery care at a public hospital in Nelson Mandela Bay. A qualitative, descriptive and explorative research design was used in the study. Data were collected from 11 purposively criterion-selected mothers who had a caesarean section delivery. One-on-one semi-structured interviews were conducted in the post-natal wards. Research ethics, namely autonomy, beneficence, justice and informed consent, were adopted in the study. All participants were informed of their right to withdraw from the study at any stage without penalties. Interviews were analysed using Tesch's method of data analysis. Three main themes were identified as experiences of: diverse pain, physical limitation and frustration and health care services as different. Experiences of mothers following a caesarean section delivery with midwifery services at a public hospital in Nelson Mandela Bay were explored and described as diverse. A need for adequate pain management as well as assistance and breastfeeding support to mothers following caesarean delivery was identified as crucial to promote a good mother-to-child relationship.

The treatment of post-surgical wound complications, such as surgical site infections and surgical wound dehiscence, generates a significant burden for patients and healthcare systems. The effectiveness of negative pressure wound therapy has been under investigation but to date no systematic review has been published in relation to its effectiveness in the prevention of surgical wound complications. To identify the effectiveness of negative pressure wound therapy in the prevention of post-surgical wound complications in adults with a closed surgical incision compared to standard surgical dressings. Male and female adults who have had negative pressure wound therapy applied to their surgical incision following a procedure in one of the following areas: trauma, cardiothoracic, orthopedic, abdominal, or vascular surgery.The intervention of interest was the use of negative pressure wound therapy directly over an incision following a surgical procedure; the comparator was standard surgical dressings.Both experimental and epidemiological study designs, including randomized controlled trials, pseudo-randomized trials, quasi-experimental studies, before and after studies, prospective and retrospective cohort studies, case control studies, and analytical cross sectional studies were sought.The primary outcome was the occurrence of post-surgical wound infection or dehiscence as measured by the following: surgical site infections - superficial and deep; surgical wound dehiscence; wound pain; wound seroma; wound hematoma. Published and unpublished studies in English from 1990 to 2013 were identified by searching a variety of electronic databases. Reference lists of all papers selected for retrieval were then searched for additional studies. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-Analysis of

Primary closure versus delayed closure for non bite traumatic wounds within 24 hours post injury.

2013-10-22

Acute traumatic wounds are one of the common reasons why people present to the emergency department. Primary closure has traditionally been reserved for traumatic wounds presenting within six hours of injury and considered 'clean' by the attending surgeon, with the rest undergoing delayed primary closure as a means of controlling wound infection. Primary closure has the potential benefit of rapid wound healing but poses the potential threat of increased wound infection. There is currently no evidence to guide clinical decision-making on the best timing for closure of traumatic wounds. To determine the effect on time to healing of primary closure versus delayed closure for non bite traumatic wounds presenting within 24 hours post injury. To explore the adverse effects of primary closure compared with delayed closure for non bite traumatic wounds presenting within 24 hours post injury. In May 2013, for this first update we searched the Cochrane Wounds Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. There were no restrictions with respect to language, date of publication or study setting. Randomised controlled trials comparing primary closure with delayed closure of non bite traumatic wounds. Two review authors independently evaluated the results of the searches against the inclusion criteria. No studies met the inclusion criteria for this review. Since no studies met the inclusion criteria, neither a meta-analysis nor a narrative description of studies was possible. There is currently no systematic evidence to guide clinical decision-making regarding the timing for closure of traumatic wounds. There is a need for robust research to investigate the effect of primary closure compared with delayed closure for non bite traumatic wounds presenting within 24 hours of injury.

The use of topical negative pressure (TNP) dressings for sternal wound dehiscence or mediastinitis in the neonatal population is rare. The majority of case reports have focused on wound healing as an endpoint and have not discussed the physiological advantage that TNP dressings may impart with regard to sternal stabilisation, improved respiratory function and early weaning from mechanical ventilation. We present a case of the use of TNP in neonatal post-sternotomy wound dehiscence and mediastinitis, from a UK perspective, with an emphasis on wound healing and physiological optimisation. As well as an improvement in sternal wound healing due to the local effects of the TNP system, serial arterial blood gas analysis revealed a significant improvement in systemic physiological parameters, including a reduction in pCO(2) in the period (days 20-31) after application of TNP (p<0.0001) compared to the period before where simple occlusive dressings were applied. Hydrogen ion concentration also significantly reduced in this period (p=0.0058). The use of the TNP system in association with systemic antibiotics successfully treated the mediastinitis. A sealed, controlled wound environment also allowed ease of nursing and an expedited return to care by the parents. We would recommend the consideration of TNP dressings in similar cases of neonatal and paediatric sternal wound dehiscence. Not only do we observe the local effects of improved wound healing, the systemic effects of improved lung function are also valuable in the early management of such complex cases.

Wound infiltration with local anaesthetics has been investigated as a potentially useful method for providing analgesia after caesarean delivery, but the literature is inconclusive. The objective is to assess the efficacy of local anaesthetic wound infiltration in reducing pain scores and opioid consumption in women undergoing caesarean delivery. Systematic review of randomised controlled trials with meta-analyses. MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled trials (CENTRAL) until December 2015. Randomised controlled trials that assessed the efficacy of local anaesthetic wound infiltration using an infusion or single injection technique for postcaesarean section analgesia. A total of 21 studies were included in the final analysis (11 studies using an infusion technique and 10 studies using single infiltration). Local anaesthetic wound infiltration significantly decreased opioid consumption at 24 h [mean difference -9.69 mg morphine equivalents, 95% confidence interval (CI), -14.85 to -4.52] and pain scores after 24 h at rest (mean difference -0.36, 95% CI, -0.58 to -0.14) and on movement (mean difference -0.61, 95% CI, -1.19 to -0.03). Subgroup analysis did not suggest a difference in primary outcomes between infusions and single infiltration. Opioid consumption was reduced in patients who did not receive intrathecal morphine but not in those who received intrathecal morphine, although there were very little data in patients receiving intrathecal morphine. Pain scores at rest and on movement at 24 h were reduced with catheter placement below the fascia but not above the fascia. There were no statistically significant reductions in nausea, vomiting or pruritus with local anaesthetic infiltration. Local anaesthetic wound infiltration reduces postoperative opioid consumption but had minimal effect on pain scores and did not reduce opioid-related side-effects in women who had undergone delivery by caesarean section.

Preterm delivery is often performed by Caesarean section. We investigated modes of anaesthesia and risk factors for general anaesthesia among women undergoing preterm Caesarean delivery. Women undergoing Caesarean delivery between 24(+0) and 36(+6) weeks' gestation were identified from a multicentre US registry. The mode of anaesthesia was classified as neuraxial anaesthesia (spinal, epidural, or combined spinal and epidural) or general anaesthesia. Logistic regression was used to identify patient characteristic, obstetric, and peripartum risk factors associated with general anaesthesia. Within the study cohort, 11 539 women had preterm Caesarean delivery; 9510 (82.4%) underwent neuraxial anaesthesia and 2029 (17.6%) general anaesthesia. In our multivariate model, African-American race [adjusted odds ratio (aOR)=1.9; 95% confidence interval (CI)=1.7-2.2], Hispanic ethnicity (aOR=1.5; 95% CI=1.2-1.8), other race (aOR=1.4; 95% CI=1.1-1.9), and haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome or eclampsia (aOR=2.8; 95% CI=2.2-3.5) were independently associated with receiving general anaesthesia for preterm Caesarean delivery. Women with an emergency Caesarean delivery indication had the highest odds for general anaesthesia (aOR=3.5; 95% CI=3.1-3.9). For every 1 week decrease in gestational age at delivery, the adjusted odds of general anaesthesia increased by 13%. In our study cohort, nearly one in five women received general anaesthesia for preterm Caesarean delivery. Although potential confounding by unmeasured factors cannot be excluded, our findings suggest that early gestational age at delivery, emergent Caesarean delivery indications, hypertensive disease, and non-Caucasian race or ethnicity are associated with general anaesthesia for preterm Caesarean delivery. © The Author 2015.

Back to "once a caesarean: always a caesarean"? A trend analysis in Switzerland.

Caesarean sections (CS) have significantly increased worldwide and a previous CS is nowadays an important and increasingly reported indication to perform a repeat CS. There is a paucity of information in Switzerland on the incidence of repeat CS after previous CS and relationship between the rates of vaginal birth after CS (VBAC). The aim of this study was to analyse the actual trend in VBAC in Switzerland. We performed a retrospective cohort study to analyse the proportion of VBAC among all pregnant women with previous sections which give birth during two time periods (group 1:1998/1999 vs. group 2:2004/2005) in our tertiary care referral hospital and in the annual statistics of Swiss Women's Hospitals (ASF-Statistics). In addition, the proportion of induction of labour after a previous caesarean and its success was analysed. In both cohorts studied, we found a significant decrease of vaginal births (p < 0.05) and a significant increase of primary elective repeat caesarean section (p < 0.05) from the first to the second time period, while there was a decrease of secondary repeat caesarean sections. The prevalence of labour induction did not decrease. Our study shows that vaginal birth after a prior caesarean section has decreased over time in Switzerland. There was no significant change in labour induction during the study period. While this trend might reflect an increasing demand for safety in pregnancy and childbirth, it concomitantly increases maternal risks of further pregnancies, and women need to be appropriately informed about long-term risks.

Suture repair of umbilical hernia during caesarean section: a case-control study.

The objective of this study was to investigate the additional burdens in terms of pain, prolongation of surgery and morbidity which is added to elective caesarean section if umbilical hernia suture repair is performed simultaneously. Secondly, patient's satisfaction and hernia recurrence rate were assessed. Consecutive women with symptomatic umbilical hernia undergoing internal or external suture repair during elective caesarean were included in this retrospective cohort-control study. Data on post-operative pain, duration of surgery and morbidity of a combined procedure were collected. These patients were matched 1:10 to women undergoing caesarean section only. Additionally, two subgroups were assessed separately: external and internal suture hernia repair. These subgroups were compared for patient's satisfaction, cosmesis, body image and recurrence rate. Fourteen patients with a mean age of 37 years were analysed. Internal suture repair (n = 7) prolonged caesarean section by 20 min (p = 0.001) and external suture repair (n = 7) by 34 min (p < 0.0001). Suture repair did not increase morphine use (0.38 ± 0.2 vs. 0.4 ± 02 mg/kg body weight), had no procedure-related morbidity and prolonged hospitalization by 0.5 days (p = 0.01). At a median follow-up of 37 (5-125) months, two recurrences in each surgical technique, internal and external suture repair, occurred (28 %). Body image and cosmesis score showed a higher level of functioning in internal suture repair (p = 0.02; p = 0.04). Despite a high recurrence rate, internal suture repair of a symptomatic umbilical hernia during elective caesarean section should be offered to women if requested. No additional morbidity or scar is added to caesarean section. Internal repair is faster, and cosmetic results are better, additional skin or fascia dissection is avoided, and it seems to be as effective as an external approach. Yet, women must be informed on the high recurrence rate.

A 32-year-old Caucasian primigravida was admitted for elective Caesarean Section at 36 weeks and 6 days with the diagnosis of preeclampsia. Traction of the umbilical cord after delivery of a healthy baby resulted in uterine inversion. The placenta was found to be densely adherent to the posterior uterine wall. Piecemeal excision of the placenta as close as possible to the uterine lining was then performed. In this way we were able to control a massive post partum hemorrhage and preserve the fertility of the patient.

Introduction Several countries have instituted fee exemptions for caesareans to reduce maternal and newborn mortality. Objectives To evaluate the effect of fee exemptions for caesareans on population caesarean rates taking into account different levels of accessibility. Methods The observation period was from January 2003 to May 2012 in one Region and covered 11.7 million person-years. Exemption fees for caesareans were adopted on June 26, 2005. Data were obtained from a registration system implemented in 2003 that tracks all obstetrical emergencies and interventions including caesareans. The pre-intervention period was 30 months and the post-intervention period was 83 months. We used an interrupted time series to evaluate the trend before and after the policy adoption and the overall tendency. Findings During the study period, the caesarean rate increased from 0.25 to 1.5% for the entire population. For women living in cities with district hospitals that provided caesareans, the rate increased from 1.7% before the policy was enforced to 5.7% 83 months later. No significant change in trends was observed among women living in villages with a healthcare centre or those in villages with no healthcare facility. For the latter, the caesarean rate increased from 0.4 to 1%. Conclusions After nine years of implementation policy in Mali, the caesarean rate achieved in cities with a district hospital reached the full beneficial effect of this measure, whereas for women living elsewhere this policy did not increase the caesarean rate to a level that could contribute effectively to reduce their risk of maternal death. Only universal access to this essential intervention could reduce the inequities and increase the effectiveness of this policy. PMID:25137072

Over 10% of current births in all countries of the world are delivered by caesarean section. Single-dose ampicillin or cefazolin administered after cord clamping has been proven to be effective for the prevention of post-caesarean infections as indicated in many randomised trials and reviews in the Cochrane Library. This study aimed to determine three determinants of behavioural intention using the theory of planned behaviour: attitudes, subjective norms, and perceived controls. Intentions were examined for five aspects of the use of antibiotic prophylaxis, namely whether or not antibiotics were used, used in all caesarean sections, after rather than before cord clamping, whether ampicillin/cefazolin or broader-spectrum antibiotics were used, and whether single or multiple doses were given. Fifty obstetricians selected from university, regional, and general hospitals in southern Thailand, were surveyed using a questionnaire and in-depth interview. Their intentions to use a single dose and to use in all cases were low, and this was related to negative attitudes and reference groups who did not approve of the single dose. The negative attitude was based on scepticism concerning the applicability of well-equipped trials from the developed world and fear of consequences of post-caesarean infections. Norms carried over from residency training had more long-term influence in their practice than newer information from books or journals. Perceived external controls on their practice were less predictive of intentions. Intentions were only partly predictive of behaviour. Changing attitudes, introducing evidence-based information into residency training and strengthening control systems in the hospital are essential to improve intentions.

Summary of the impact of Caesarean section on anal incontinence. Review. Department of Gynaecology and Obstetrics, Charles University and University Hospital Plzen. Review of the current international literature. Currently, Caesarean section is not considered to reduce symptoms of anal incontinence. If there is any reduction of symptoms, that remains only for a short term (40% in 3 months after the delivery in the largest trial). In a long term, virtually in no trial has been observed any difference, and others, non-obstetrical factors (particularly aging) prevail. Current knowledge does not allow to assess sufficiently pros and cons of Caesarean compared to vaginal delivery. High risk groups, that would profit from elective Ceasarean, have not been clearly identified yet.

Caesarean section: an historical riddle.

Etymologically, the word 'Caesar' originates from the Latin word 'Caedaere' meaning - 'to cut'. So cutting remains the core point, but little is known about the real origin of the history of Caesarean Section. There is evidence that, the ancient Hindus excelled in surgery and many operations were performed, including caesarean section. This operation was mentioned several times in the Mishnah of Rabbi Judah, the first large commentary on the Hebrew Bible. There are also several mythological anecdotes in Hindu, Buddhist and Greek mythologies. The myth of caesarean section did not even escape the keen eyes of William Skakespeare. The landmarks, treatises and the advancement in this operative procedure are presented in this article.

Obstetric surgical site infections (SSIs) are common and expensive to the health care system but remain under reported given shorter postoperative hospital stays and suboptimal post-discharge surveillance systems. SSIs, for the purpose of this paper, are defined according to the Center for Disease Control and Prevention (1999) as infection incurring within 30 days of the operative procedure (in this case, Caesarean section [CS]). Demonstrate the feasibility of real-life use of a patient driven SSIs post-discharge surveillance system consisting of an online database and mobile phone technology (surgical mobile app - how2trak) among women undergoing CS in a Canadian urban centre. Estimate the rate of SSIs and associated predisposing factors. Prospective cohort of consecutive women delivering by CS at one urban Canadian hospital. Using surgical mobile app-how2trak-predetermined demographics, comorbidities, procedure characteristics, and self-reported symptoms and signs of infection were collected and linked to patients' incision self-portraits (photos) on postpartum days 3, 7, 10, and 30. A total of 105 patients were enrolled over a 5-month period. Mean age was 31 years, 13% were diabetic, and most were at low risk of surgical complications. Forty-six percent of surgeries were emergency CSs, and 104/105 received antibiotic prophylaxis. Forty-five percent of patients (47/105) submitted at least one photo, and among those, one surgical site infection was detected by photo appearance and self-reported symptoms by postpartum day 10. The majority of patients whom uploaded photos did so multiple times and 43% of them submitted photos up to day 30. Patients with either a diagnosis of diabetes or self-reported Asian ethnicity were less likely to submit photos. Post-discharge surveillance for CS-related SSIs using surgical mobile app how2trak is feasible and deserves further study in the post-discharge setting. Copyright © 2017. Published by Elsevier Inc.

International migration as a determinant of emergency caesarean.

High caesarean rates are of concern given associated risks. International migrant women (women born abroad) represent a substantial proportion of women giving birth in high-income countries (HICs) and face social conditions that may exacerbate childbearing health risks. Among migrant women, emergency rather than planned caesareans, tend to be more prevalent. This method of delivery can be stressful, physically harmful and result in an overall negative birth experience. Research establishing evidence of risk factors for emergency caesareans in migrants is insufficient. (1) Describe potential pathways (with a focus on modifiable factors) by which migration, using internationally recommended migration indicators: country of birth, length of time in country, fluency in receiving-country language, migration classification and ethnicity, may lead to emergency caesarean; and (2) propose a framework to guide future research for understanding "potentially preventable" emergency caesareans in migrant women living in HICs. "Potentially preventable" emergency caesareans in migrant women are likely due to several modifiable, interrelated factors pre-pregnancy, during pregnancy and during labour. Migration itself is a determinant and also shapes other determinants. Complications and ineffective labour progress and/or foetal distress and ultimately the decision to perform an emergency caesarean may be the result of poor health (i.e., physiological effects), lack of support and disempowerment (i.e., psychological effects) and sub-optimal care. Understanding the direct and indirect effects of migration on emergency caesarean is crucial so that targeted strategies can be developed and implemented for reducing unnecessary caesareans in this vulnerable population.

in light of the rising caesarean section rates in many developing countries, we sought to explore women's and caregivers' experiences, perceptions, attitudes, and beliefs in relation to caesarean section. qualitative study using semi-structured individual in-depth interviews, focus group discussions, and participant observations. The study relied on a framework of naturalistic inquiry and data were analysed using thematic analysis. a public university hospital in Dar es Salaam, Tanzania. we conducted a total of 29 individual interviews, 13 with women and 16 with caregivers, and two focus group discussions comprising five to six caregivers each. Women had undergone a caesarean section within two months preceding the interview and were interviewed in their homes. Caregivers were consultants, specialists, residents, and midwives. both women and caregivers preferred vaginal birth, but caregivers also had a favourable attitude towards caesarean section. While caregivers emphasised their efforts to counsel women on caesarean section, women had often reacted with fear and shock to the caesarean section decision and perceived that there was a lack of indications. Although caesarean section was perceived as involving higher maternal risks than vaginal birth, both women and caregivers justified these risks by the need to 'secure' a healthy baby. Religious beliefs and community members seemed to influence women's caesarean section attitudes, which often made caregivers frustrated as it diminished their role as decision-makers. Undergoing caesarean section had negative socio-economic consequences for women and their families; however, caregivers seldom took these factors into account when making decisions. we raise a concern that women and caregivers might overlook maternal risks with caesarean section for the benefit of the baby, a shift in focus that can have serious consequences on women's health in low-resource settings. Caregivers need to reflect on how they counsel women

This retrospective study was conducted to identify the incidence and characteristics associated with readmissions for surgical site infections following caesarean section in a tertiary hospital from 2012 to 2015. Of 6334 patients who underwent caesarean section, 165 (2.6%) were readmitted, most commonly for surgical site infection (25.5%, n = 42). Thirty-seven of these patients (88%) had an emergency caesarean compared to five (12%) following an elective caesarean section. Of the women with surgical site infections, 69% were overweight and 14% had diabetes. Emergency caesarean sections were responsible for the majority of readmissions, particularly in women with co-morbidities that predisposed them to infection. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Cost-effectiveness analysis alongside a pilot study of prophylactic negative pressure wound therapy.

Negative pressure wound therapy (NPWT) is increasingly used prophylactically following surgery despite limited evidence of clinical or cost-effectiveness. To evaluate whether NPWT is cost-effective compared to standard care, for the prevention of surgical site infection (SSI) in obese women undergoing elective caesarean section, and inform development of a larger trial. An economic evaluation was conducted alongside a pilot randomised controlled trial at one Australian hospital, in which women were randomised to NPWT (n = 44) or standard care (n = 43). A public health care provider perspective and time horizon to four weeks post-discharge was adopted. Cost-effectiveness assessment was based on incremental cost per SSI prevented and per quality-adjusted life year (QALY) gained. Patients receiving NPWT each received health care costing AU$5887 (±1038) and reported 0.069 (±0.010) QALYs compared to AU$5754 (±1484) and 0.066 (±0.010) QALYs for patients receiving standard care. NPWT may be slightly more costly and more effective than standard care, with estimated incremental cost-effectiveness ratios (ICERs) of AU$1347 (95%CI dominant- $41,873) per SSI prevented and AU$42,340 (95%CI dominant- $884,019) per QALY gained. However, there was considerable uncertainty around these estimates. NPWT may be cost-effective in the prophylactic treatment of surgical wounds following elective caesarean section in obese women. Larger trials could clarify the cost-effectiveness of NPWT as a prophylactic treatment for SSI. Sensitive capture of QALYs and cost offsets will be important given the high level of uncertainty around the point estimate cost-effectiveness ratio which was close to conventional thresholds.

randomisation.Three comparisons were included. 1. Tocolysis versus no tocolysisA single randomised trial involving 97 women was identified and included in the review. Birth trauma was not reported. There were no cases of any maternal side-effect reported in either the nitroglycerin or the placebo group. No other maternal and infant health outcomes were reported. 2. Reverse breech extraction versus head push for the deeply impacted head at full dilation at caesarean section Four randomised trials involving 357 women were identified and included in the review. The primary outcome of birth trauma was reported by three trials and there was no difference between reverse breech extraction and head push for this rare outcome (three studies, 239 women, risk ratio (RR) 1.55, 95% confidence interval (CI) 0.42 to 5.73). Secondary outcomes including endometritis rate (three studies, 285 women, average RR 0.52, 95% CI 0.26 to 1.05, Tau I² = 0.22, I² = 56%), extension of uterine incision (four studies, 357 women, average RR 0.23, 95% CI 0.13 to 0.40), mean blood loss (three studies, 298 women, mean difference (MD) -294.92, 95% CI -493.25 to -96.59; I² = 98%) and neonatal intensive care unit (NICU)/special care nursery (SCN) admission (two studies, 226 babies, average RR 0.53, 95% CI 0.23 to 1.22, Tau I² = 0.27, I² = 74%) were decreased with reverse breech extraction. No differences were observed between groups for many of the other secondary outcomes reported (blood loss > 500 mL; blood transfusion; wound infection; mean hospital stay; average Apgar score).There was significant heterogeneity between the trials for the outcomes mean blood loss, operative time and mean hospital stay, making comparison difficult. However the operation duration was significantly shorter for reverse breech extraction, which may correspond with ease of delivery and therefore, the amount of tissue trauma and therefore, significantly less blood loss. Given the heterogeneity, we cannot define the amount of

Caesarean section is the most common surgical procedure performed on women world-wide. It is recommended when vaginal delivery might pose a risk to the mother or baby. This review examines the history and developments in caesarean section techniques over the years as well as the difficulties that may be encountered in each stage in our environment. A review of relevant literature was conducted using Pubmed and e-medicine websites for computer search. The following keywords were used: history, development, techniques and caesarean section. Relevant review articles, Cochrane database and chapters in text books were also used to extract information. Though practiced since ancient times, the history of caesarean section remains shrouded in myths as no document describing its indication and techniques is still available. Ancient medical writers like Galen, Hippocrates and Soranus made no mention of the procedure. However, the evidence that it was performed arose from legal texts. The development in its technique was gradual over many years. The development of caesarean section technique occurred with the withdrawal of surgeries from the stronghold of religion in Renaissance time. Operative techniques vary and this has continued to improve through many years of trial and error.

Closure versus non-closure of the peritoneum at caesarean section: short- and long-term outcomes

visceral peritoneum only versus closure of both peritoneal surfaces Three trials involving 889 women were analysed. There was an increase in adhesion formation (two trials involving 157 women, RR 2.49, 95% CI 1.49 to 4.16) which was limited to one trial with high risk of bias.There was reduction in operative time, postoperative days in hospital and wound infection. There was no significant reduction in postoperative pyrexia. 3. Non-closure of parietal peritoneum only versus closure of both peritoneal layers The two identified trials involved 573 women. Neither study reported on postoperative adhesion formation. There was reduction in operative time and postoperative pain with no difference in the incidence of postoperative pyrexia, endometritis, postoperative duration of hospital stay and wound infection. In only one study, postoperative day one wound pain assessed by the numerical rating scale, (MD -1.60, 95% CI -1.97 to -1.23) and chronic abdominal pain d by the visual analogue score (MD -1.10, 95% CI -1.39 to -0.81) was reduced in the non-closure group. 4. Non-closure versus closure of visceral peritoneum when parietal peritoneum is closed There was reduction in all the major urinary symptoms of frequency, urgency and stress incontinence when the visceral peritoneum is left unsutured. Authors’ conclusions There was a reduction in operative time across all the subgroups. There was also a reduction in the period of hospitalisation postcaesarean section except in the subgroup where parietal peritoneum only was not sutured where there was no difference in the period of hospitalisation. The evidence on adhesion formation was limited and inconsistent. There is currently insufficient evidence of benefit to justify the additional time and use of suture material necessary for peritoneal closure. More robust evidence on long-term pain, adhesion formation and infertility is needed. Plain Language Summary Closure versus non-closure of the peritoneum at caesarean section: long

To find the effectiveness of hyaluronic acid in post-tonsillectomy pain relief and wound healing. Fifty patients were included in this prospective, double-blind, controlled clinical study (20 males, 30 females mean age of 13.56 years). Hyaluronic acid was applied to one side and the other side was used as a control during tonsillectomy. Therefore, the same patient evaluated and scored the post-tonsillectomy pain, excluding individual bias. Results indicated that patients had significantly lower pain scores for hyaluronic acid treated side (p<0.001). At the end of two weeks follow-up period, the wound in the hyaluronic acid side was almost completely healed, indicating that the healing was faster with hyaluronic acid compared to control side (p<0.001). Hyaluronic acid could be recommended as an effective treatment for the management of post-tonsillectomy pain and wound healing. Copyright © 2015. Published by Elsevier Ireland Ltd.

Atelectasis after either vaginal or Caesarean delivery has not been adequately quantified. This study addresses the hypothesis that atelectasis may be worse in women who undergo Caesarean section when compared with vaginal delivery under regional anaesthesia. Twenty healthy non-smoking women submitted to a chest computed tomography (CT) 2 h after delivery in a University Hospital, who had experienced vaginal delivery (n=10) under combined spinal-epidural analgesia or a Caesarean section (n=10) under spinal anaesthesia, were evaluated. The percentage cross-sectional area of atelectasis in dependent lung regions were measured from the CT images obtained at cross-section of the xiphoid process and the top of the diaphragm. The percentage cross-sectional area of atelectasis was 3.95% in the vaginal delivery group and 14.1% in the Caesarean group (P<0.001, Mann-Whitney rank sum test). These results suggested that pulmonary atelectasis is greater after Caesarean section delivery under spinal anaesthesia than after vaginal delivery with combined spinal-epidural analgesia.

Myomectomy at the time of caesarean delivery has been discouraged because of the risk of intractable haemorrhage and increased postoperative morbidity. The aim of this study is to determine the safety and feasibility of caesarean myomectomy. A retrospective case control study done between June 2012 to May 2013 in a tertiary care teaching hospital in Karnataka, India which included 21 pregnant women with uterine fibroids who underwent myomectomy during caesarean section and were compared with 42 matched controls without uterine fibroids who had caesarean section alone during the same period. Primary outcome measures studied were incidence of haemorrhage and need for blood transfusion. Secondary outcome measures were duration of operation, length of hospital stay, postpartum fever and wound infection. Statistical analysis is done using IBMSPSS 20.0 software and students t-test. For calculation of incidence of haemorrhage Fisher's exact test is used. Mean age of the 21 cases was 31.81yrs and 47.62% were primigravida. Total 37 fibroids were removed. Subserosal were 30 cases(81.08%) while 1(2.07%) was submucous. 21(56.76%)fibroids were situated in fundal region and 3(8.11%) were in lower segment. Mean change in the haemoglobin from preoperative to postoperative period in the cases was 1.3gm/dl(±1.155mg/dl) and control was 1.05% (±.854mg/dl). Two of the cases(9.52%) required blood transfusion compared to none in control. None in either group required hysterectomy. Mean duration of surgery was 68.57min (±15.012min)and 51.55min (±9.595min) for controls which is statistically significant. This study shows that myomectomy during caesarean section is a safe procedure and is not associated with major intraoperative and postoperative complications.

An overview of the health economic implications of elective caesarean section.

2013-12-01

The caesarean section rate has continued to increase in most industrialised countries, which raises a number of economic concerns. This review provides an overview of the health economic implications of elective caesarean section. It provides a succinct summary of the health consequences associated with elective caesarean section for both the infant and the mother over the perinatal period and beyond. It highlights factors that complicate our understanding of the health consequences of elective caesarean section, including inconsistencies in definitions and coding of the procedure, failure to adopt an intention-to-treat principle when drawing comparisons, and the widespread reliance on observational data. The paper then summarises the economic costs associated with elective caesarean section. Evidence is presented to suggest that planned caesarean section may be less costly than planned vaginal birth in some clinical contexts, for example where the singleton fetus lies in a breech position at term. In contrast, elective caesarean section (or caesarean section as a whole) appears to be more costly than vaginal delivery (either spontaneous or instrumented) in low-risk or unselected populations. The paper proceeds with an overview of economic evaluations associated with elective caesarean section. All are currently based on decision-analytic models. Evidence is presented to suggest that planned trial of labour (attempted vaginal birth) following a previous caesarean section appears to be a more cost-effective option than elective caesarean section, although its cost effectiveness is dependent upon the probability of successful vaginal delivery. There is conflicting evidence on the cost effectiveness of maternal request caesareans when compared with trial of labour. The paucity of evidence on the value pregnant women, clinicians and other groups in society place on the option of elective caesarean section is highlighted. Techniques that might be used to elicit

Angiogenesis is critical for wound healing. Insufficient angiogenesis can result in impaired wound healing and chronic wound formation. Electrical stimulation (ES) has been shown to enhance angiogenesis. We previously showed that ES enhanced angiogenesis in acute wounds at one time point (day 14). The aim of this study was to further evaluate the role of ES in affecting angiogenesis during the acute phase of cutaneous wound healing over multiple time points. We compared the angiogenic response to wounding in 40 healthy volunteers (divided into two groups and randomised), treated with ES (post-ES) and compared them to secondary intention wound healing (control). Biopsy time points monitored were days 0, 3, 7, 10, 14. Objective non-invasive measures and H&E analysis were performed in addition to immunohistochemistry (IHC) and Western blotting (WB). Wound volume was significantly reduced on D7, 10 and 14 post-ES (p = 0.003, p = 0.002, p<0.001 respectively), surface area was reduced on days 10 (p = 0.001) and 14 (p<0.001) and wound diameter reduced on days 10 (p = 0.009) and 14 (p = 0.002). Blood flow increased significantly post-ES on D10 (p = 0.002) and 14 (p = 0.001). Angiogenic markers were up-regulated following ES application; protein analysis by IHC showed an increase (p<0.05) in VEGF-A expression by ES treatment on days 7, 10 and 14 (39%, 27% and 35% respectively) and PLGF expression on days 3 and 7 (40% on both days), compared to normal healing. Similarly, WB demonstrated an increase (p<0.05) in PLGF on days 7 and 14 (51% and 35% respectively). WB studies showed a significant increase of 30% (p>0.05) on day 14 in VEGF-A expression post-ES compared to controls. Furthermore, organisation of granulation tissue was improved on day 14 post-ES. This randomised controlled trial has shown that ES enhanced wound healing by reduced wound dimensions and increased VEGF-A and PLGF expression in acute cutaneous wounds, which further substantiates the role of ES in up

The rate of caesarean sections at full cervical dilatation with their high risk of morbidity continues to rise mirroring the overall increase in caesarean section rates internationally. The objectives of this study were to determine the rate of full dilatation caesarean section in a tertiary referral unit and evaluate key labour, maternal and fetal factors potentially linked to those deliveries. We also assessed maternal and fetal morbidity at full dilatation sections. Where possible, these were compared with successful operative vaginal deliveries carried out in theatre to determine key differences. Retrospective cohort study. We reviewed the rate of full dilatation caesarean section over a 10-year period. We analysed deliveries (caesarean sections or operative vaginal deliveries) in single cephalic pregnancies ≥34 weeks with contemporaneously collected data from our unit's electronic database for 2015. The rate of full dilatation caesarean section increased by over a third in the ten-year period (56/6947 (0.80%) vs 92/7378 (1.24%), p = 0.01). Of 84 full dilatation caesarean sections who met the inclusion criteria, 63 (75%) were nulliparous and the mean maternal age was 33 (±5) years. Oxytocin was used in the second stage in less than half of second stage caesarean sections (22 out of a recorded 57, 38.6%). There were more fetal head malposition (occipito-posterior, or occipito-transverse) at full dilatation caesarean section compared to successful operative vaginal deliveries (41/46 (89.1%) vs 2/21 (9.5), p < 0.001). The rate of significant postpartum haemorrhage (defined as estimated blood loss ≥1000 ml) was similar in both full dilatation caesarean section and operative vaginal deliveries. There was no difference in the mean birthweight at full dilatation caesarean sections compared to operative vaginal delivery (3.88 kg (2.80-5.33 kg) vs 3.48 kg (1.53-4.40 kg)). There was no difference in neonatal morbidity. Fetal head malposition is

To assess the quality and comprehensiveness of the information on caesarean section provided in Brazilian women's magazines. Review of articles published during 1988-2008 in top selling women's magazines. Brazil, one of the countries with the highest caesarean section rates in the world. Women's magazines with the largest distribution during the study period, identified through the official national media indexing organisations. Articles with objective scientific information or advice, comments, opinions, or the experience of ordinary women or celebrities on delivery by caesarean section. Sources of information mentioned by the author of the article, the accuracy and completeness of data presented on caesarean section, and alleged reasons why women would prefer to deliver though caesarean section. 118 articles were included. The main cited sources of information were health professionals (78% (n=92) of the articles). 71% (n=84) of the articles reported at least one benefit of caesarean section, and 82% (n=97) reported at least one short term maternal risk of caesarean section. The benefits most often attributed to delivery by caesarean section were reduction of pain and convenience for family or health professionals. The most frequently reported short term maternal risks of caesarean section were increased time to recover and that it is a less natural way of giving birth. Only one third of the articles mentioned any long term maternal risks or perinatal complications associated with caesarean section. Fear of pain was the main reported reason why women would prefer to deliver by caesarean section. Most of the articles published in Brazilian women's magazines do not use optimal sources of information. The portrayal of caesarean section is mostly balanced, not explicitly in favour of one or another route of delivery, but incomplete and may be leading women to underestimate the maternal/perinatal risks associated with this route of delivery.

To describe the rate of caesarean sections in Mexico in the last 10 years and evaluate its relationship with several socioeconomic variables, type of health care services, and specialists' availability. The Ministry of Health's register of births was used as source of information. The dependent variable was the type of delivery (vaginal or caesarean). The independent variables were: gross domestic product, human development index, illiteracy percentage among women, social exclusion index and, gynecology and obstetrics specialists supply. Correlations between variables were evaluated using Pearson's parametric test and Spearman range test. A lineal multiple regression was used to model the national caesarean data of 1999. National caesarean percentage increased in the last 10 years at an annual rate of 1%. It was considerably higher in social security institutions and the private sector. Caesareans percentages in 1999 were slightly above 35%. The highest values were those of the private sector with 53%, followed by social security institutions, with 38.2%. The variables more strongly associated with C sections were GDP, specialists' availability and human development index. It seems reasonable to advocate for a widespread descent in caesarean sections in Mexico. Important declines in certain contexts have been witnessed by implementing measures such as a second opinion before any C-section, a precise definition of the reasons for using it, and the monitoring of individual caesarean percentage among hospital obstetricians.

Effective postoperative analgesia after emergency caesarean section is important because it provides early recovery, ambulation and breast-feeding. The ultrasound-guided erector spinae plane block has been orginally described for providing thoracic analgesia at the T5 transverse process by Forero et al. We performed post-operative bilateral erector spinae plane blocks with 20ml bupivacaine 0.25% at the level of the T9 transverse process in a pregnant woman after caesarean section. In this report, we described that bilateral erector spinae plane block at T9 level provides effective and long-lasting postoperative analgesia for lower abdominal surgery.

In a previous study, we proposed a new therapy using topical bromelain as a supplement to simple wound-track incision for the debridement of firearm wounds. This enzymatic debridement greatly simplified the management of high-velocity gunshot wounds in a pig model, and bromelain was confirmed to improve wound healing. The purpose of the present study was to investigate the effect of bromelain on the microenvironment of firearm wounds. Sixteen Chinese landrace pigs wounded by high-velocity projectiles were divided randomly into four groups: wound incision (group I), incision + bromelain (group IB), wound excision (group E), and control. Blood perfusion, oxygen partial pressure (pO(2)), and the content of tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β in wound-track tissue were measured. Wound healing was also noted. The recovery of blood perfusion in tissue and pO(2) in wound tracks was significantly more rapid in group IB and group E than in group I and control. The tissue level of TNF-α was significantly lower in group IB than in group I and control 48 h and 72 h post-wounding, and was lower than in group E 48 h post-wounding. The tissue level of TGF-β in group IB was sustained at a significantly higher level than in the other three groups. Wound healing time was also shorter in group IB. Enzymatic debridement using topical bromelain in incised wound tracks accelerates the recovery of blood perfusion, pO(2) in wound tissue, controls the expression of TNF-α and raises the expression of TGF-β.

The aim of the study is to investigate the benefits and the limits in using the soft cup vacuum extractor on the fetal scalp during the caesarean section. The prospective study includes 19 cases of caesarean sections (group A), with vacuum assisted delivery using the soft cup vacuum extractor on the fetal scalp (diameter 6 cm) and 25 cases (group B) of caesarean sections with usual, manual extraction of the head assisted by fundal compression. All of the patients had undergone a planned caesarean section on term in absence of uterine activity and preserved amniotic membranes. Our results doesn't show differences in the Apgar score on the first and 5-th minute in the newborns of the two groups. The duration of the scalp traction was significantly shorter (30 +/- 4 sec) in comparison to the classical manual extraction (53 +/- 21 sec). The mean duration for applying the vacuum cup was 10 sec and 25 sec for tractions. The total blood loose and total duration of the caesarean sections were shorter than in the control group. The applied traction with the vacuum cup was sufficient for head extraction and there was no need for additional fundal compression. In conclusion we consider that the extraction of the fetal head in high position in caesarean section with vacuum extractor is an easy, non traumatic and rapid method which can put away the need of rough and prolonged fundal compression and its consequences.

To determine the economic impact of the introduction of carbetocin for the prevention of postpartum haemorrhage (PPH) at caesarean section, compared to oxytocin. The model is a decision tree conducted from a UK National Health Service perspective. 1500 caesarean sections (both elective and emergency) were modelled over a 12 month period. Efficacy data was taken from a published Cochrane meta-analysis, and costs from NHS Reference costs, the British National Formulary and the NHS electronic Medicines Information Tool. A combination of hospital audit data and expert input from an advisory board of clinicians was used to inform resource use estimates. The main outcome measures were the incidence of PPH and total cost over a one year time horizon, as a result of using carbetocin compared to oxytocin for prevention of PPH at caesarean section. The use of carbetocin compared to oxytocin for prevention of PPH at caesarean section was associated with a reduction of 30 (88 vs 58) PPH events (>500ml blood loss), and a cost saving of £27,518. In probabilistic sensitivity analysis, carbetocin had a 91.5% probability of producing better outcomes, and a 69.4% chance of being dominant (both cheaper and more effective) compared to oxytocin. At list price, the introduction of carbetocin appears to provide improved clinical outcomes along with cost savings, though this is subject to uncertainty regarding the underlying data in efficacy, resource use, and cost.

Broad-Spectrum Inhibition of the CC-Chemokine Class Improves Wound Healing and Wound Angiogenesis.

PubMed

Ridiandries, Anisyah; Bursill, Christina; Tan, Joanne

2017-01-13

Angiogenesis is involved in the inflammation and proliferation stages of wound healing, to bring inflammatory cells to the wound and provide a microvascular network to maintain new tissue formation. An excess of inflammation, however, leads to prolonged wound healing and scar formation, often resulting in unfavourable outcomes such as amputation. CC-chemokines play key roles in the promotion of inflammation and inflammatory-driven angiogenesis. Therefore, inhibition of the CC-chemokine class may improve wound healing. We aimed to determine if the broad-spectrum CC-chemokine inhibitor "35K" could accelerate wound healing in vivo in mice. In a murine wound healing model, 35K protein or phosphate buffered saline (PBS, control) were added topically daily to wounds. Cohorts of mice were assessed in the early stages (four days post-wounding) and in the later stages of wound repair (10 and 21 days post-wounding). Topical application of the 35K protein inhibited CC-chemokine expression (CCL5, CCL2) in wounds and caused enhanced blood flow recovery and wound closure in early-mid stage wounds. In addition, 35K promoted neovascularisation in the early stages of wound repair. Furthermore, 35K treated wounds had significantly lower expression of the p65 subunit of NF-κB, a key inflammatory transcription factor, and augmented wound expression of the pro-angiogenic and pro-repair cytokine TGF-β. These findings show that broad-spectrum CC-chemokine inhibition may be beneficial for the promotion of wound healing.

2014-09-01

A Cochrane Systematic Review of randomised controlled trials of epidural analgesia compared with other or no analgesia in labour reported no overall increased risk of caesarean delivery. However, many trials were affected by substantial non-compliance, and there are concerns about the external validity of some trials for contemporary maternity populations. We aimed to explore the association between epidural analgesia in labour and caesarean delivery in clinical practice and compare with findings from randomised controlled trials. Population-based cohort of pregnant women (n = 210 708) without major obstetrical complications who delivered a singleton live infant in hospitals in New South Wales, Australia, 2007-10. Data were obtained from linked, validated population-based data collections. Propensity score matching was used to examine the association between epidural analgesia in labour and caesarean delivery. Epidural analgesia in labour was used by a third (31.5%, n = 66 317) of the women, and 9.8% (n = 20 531) had a caesarean delivery. Epidural analgesia in labour was associated with increased risk of caesarean delivery {risk ratio [RR] 2.5, [95% confidence interval (CI) 2.5, 2.6]}. The association with epidural analgesia in labour was higher for caesarean delivery for failure to progress {RR 3.0, [95% CI 2.9, 3.0]} than for caesarean delivery for fetal distress {RR 1.9, [95% CI 1.8, 2.0]}. Epidural analgesia in labour is associated with caesarean delivery in a large maternity population. Population-based studies contribute important data about obstetrical care, when research settings and participants may not represent the clinical settings or broader population in which obstetrical interventions in labour are applied. © 2014 John Wiley & Sons Ltd.

Background Clinical officers perform much of major emergency surgery in Malawi, in the absence of medical officers. The aim of this study was to validate the advantages and disadvantages of delegation of major obstetric surgery to non-doctors. Methods During a three month period, data from 2131 consecutive obstetric surgeries in 38 district hospitals in Malawi were collected prospectively. The interventions included caesarean sections alone and those that were combined with other interventions such as subtotal and total hysterectomy repair of uterine rupture and tubal ligation. All these surgeries were conducted either by clinical officers or by medical officers. Results During the study period, clinical officers performed 90% of all straight caesarean sections, 70% of those combined with subtotal hysterectomy, 60% of those combined with total hysterectomy and 89% of those combined with repair of uterine rupture. A comparable profile of patients was operated on by clinical officers and medical officers, respectively. Postoperative outcomes were almost identical in the two groups in terms of maternal general condition – both immediately and 24 hours postoperatively – and regarding occurrence of pyrexia, wound infection, wound dehiscence, need for re-operation, neonatal outcome or maternal death. Conclusion Clinical officers perform the bulk of emergency obstetric operations at district hospitals in Malawi. The postoperative outcomes of their procedures are comparable to those of medical officers. Clinical officers constitute a crucial component of the health care team in Malawi for saving maternal and neonatal lives given the scarcity of physicians. PMID:17570847

A nulliparous non-descript mare was presented with a complaint of dystocia. The mare was recumbent and physical examination revealed that the animal was in shock. There was no straining and foetal forelimbs were visible outside the vulva. The foetus was dead as there was no pedal reflex. Vaginal examination revealed anterior presentation with dorso-sacral position and rigid lateral head deviation. Pre-operatively, the mare was given 5 ml Tetanus toxoid and 3 g Ceftriaxone as intramuscular injection, and 5 ml Dexamethasone in 15 L of 5% Dextrose Normal Saline (DNS) as intravenous (i/v) infusion. As pelvic space was inadequate and the mal posture was not correctable, manual correction or foetotomy could not be attempted and therefore caesarean section was planned. Condition of the animal warranted the use of local anaesthetic infiltration instead of general anesthesia. Post-operative care included intravenous fluids, anti-inflammatory/analgesics and daily antiseptic dressing. The owner reported uneventful recovery. The authors would like to conclude the case as a rare emergency caesarean in equine where the surgery was done with animal in lateral recumbency employing a Marcenac incision under local anaesthesia.

To evaluate the extent to which implementing a hospital policy to limit planned caesarean deliveries before 39 weeks of gestation improved neonatal health, maternal health, and healthcare costs. Retrospective cohort study. British Columbia Women's Hospital, Vancouver, Canada, in the period 2005-2012. Women with a low-risk planned repeat caesarean delivery. An interrupted time series design was used to evaluate the policy to limit planned caesarean deliveries before 39 weeks of gestation, introduced on 1 April 2008. Composite adverse neonatal health outcome (respiratory morbidity, 5-minute Apgar score of <7, neonatal intensive care unit admission, mortality), postpartum haemorrhage, obstetrical wound infection, out-of-hour deliveries, length of stay, and healthcare costs. Between 2005 and 2008, 60% (1204/2021) of low-risk planned caesarean deliveries were performed before 39 weeks of gestation. After the introduction of the policy, the proportion of planned caesareans dropped by 20 percentage points (adjusted risk difference of 20 fewer cases per 100 deliveries; 95% CI -25.8, -14.3) to 41% (1033/2518). The policy had no detectable impact on adverse neonatal outcomes (2.2 excess cases per 100; 95% CI -0.4, 4.8), maternal complications, or healthcare costs, but increased the risk of out-of-hours delivery from 16.2 to 21.1% (adjusted risk difference 6.3 per 100; 95% CI 1.6, 10.9). We found little evidence that a hospital policy to limit planned caesareans before 39 weeks of gestation reduced adverse neonatal outcomes. Hospital administrators intending to introduce such policies should anticipate, and plan for, modest increases in out-of-hours and emergency-timing. © 2015 Royal College of Obstetricians and Gynaecologists.

Background The overall caesarean rate in France has increased from 14.3% in 1994–1996 to 21.0% in 2010. This increased rate is a concern in all developed countries: delivery by caesarean induces both short- and long-term maternal complications, and its use requires careful reflection. The principal objective of this work was to describe the global appropriateness of indications for caesareans among a selected sample of planned caesareans performed within the Auvergne perinatal health network. The secondary objectives were to describe the inappropriate planned caesarean risk according to the maternity unit level and the impact of this medical assessment on the global caesarean rate in this network. Methods This audit among maternity units belonging to the Auvergne perinatal network in France included women who had a planned caesarean at term, were nulliparous or primiparous, and had a singleton pregnancy in cephalic presentation or a twin pregnancy with twin 1 in cephalic presentation. We used the French guidelines issued from 1998 through 2010 as our benchmark for appropriateness. Result We analysed 192 cases (100% of the records eligible for the audit). The rate of appropriate caesareans among these planned caesareans was 65.6%. Among the inappropriate caesareans, the rate of “maternal-preference” caesareans was 12.0% and the rate of “provider-preference” caesareans 22.4%. The risk of an inappropriate caesarean did not differ statistically between the level I and level II maternity wards, each compared to the level III hospital. The overall caesarean rate in our entire network decreased from 20.5% to 18.5% (p < 0.001) in the year after the audit. It also decreased in 8 of the network’s 10 maternity units, although the difference was statistically significant only in 2. Conclusions About one third of planned caesareans were inappropriate in our sample and our audit appeared to have some effect on medical practice in the short run. PMID:24716672

There is global concern about rising caesarean section rates. Identification of risk factors could lead to preventative measures. To describe the association between neonatal head circumference and (i) caesarean section for failure to progress, (ii) intrapartum caesarean section overall. This was a retrospective cohort study of 11 687 singleton live births with cephalic presentation, attempted vaginal birth and at least 37 completed weeks gestation from January 2005 to June 2009. Neonatal head circumference was grouped into quartiles and multiple logistic regressions performed. The rates of caesarean section for failure to progress were 4.1, 6.4, 8.8 and 14.3% in successive head circumference quartiles. Rates of intrapartum caesarean section overall were 8.7, 12.1, 15.8 and 21.5%. The odds ratios for caesarean section for failure to progress were: 1.00, 1.33 (95% CI 1.02- 1.73), 1.54 (1.18-2.02) and 1.93 (1.44-2.57) for successive head circumference quartiles after adjusting for multiple demographic and clinical factors. The adjusted odds ratios for intrapartum caesarean section for any indication were: 1.00, 1.52 (95% CI 1.24-1.87), 1.99 (1.62-2.46) and 2.38 (1.89-3.00), respectively. There is a strong positive relationship between head circumference quartile and both caesarean section for failure to progress and caesarean for any indication. If this finding is confirmed using ultrasound measurements, there is potential for head circumference to be incorporated into predictive models for intrapartum caesarean section with a view to offering interventions to reduce the risk of caesarean section. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Poor outcomes after breech birth might be the result of underlying conditions causing breech presentation or due to factors associated with the delivery. To assess the effects of planned caesarean section for singleton breech presentation at term on measures of pregnancy outcome. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2015). Randomised trials comparing planned caesarean section for singleton breech presentation at term with planned vaginal birth. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Three trials (2396 participants) were included in the review. Caesarean delivery occurred in 550/1227 (45%) of those women allocated to a vaginal delivery protocol and 1060/1169 (91%) of those women allocated to planned caesarean section (average risk ratio (RR) random-effects, 1.88, 95% confidence interval (CI) 1.60 to 2.20; three studies, 2396 women, evidence graded low quality). Perinatal or neonatal death (excluding fatal anomalies) or severe neonatal morbidity was reduced with a policy of planned caesarean section in settings with a low national perinatal mortality rate (RR 0.07, 95% CI 0.02 to 0.29, one study, 1025 women, evidence graded moderate quality), but not in settings with a high national perinatal mortality rate (RR 0.66, 95% CI 0.35 to 1.24, one study, 1053 women, evidence graded low quality). The difference between subgroups was significant (Test for subgroup differences: Chi² = 8.01, df = 1 (P = 0.005), I² = 87.5%). Due to this significant heterogeneity, a random-effects analysis was performed. The average overall effect was not statistically significant (RR 0.23, 95% CI 0.02 to 2.44, one study, 2078 infants). Perinatal or neonatal death (excluding fatal anomalies) was reduced with planned caesarean section (RR 0.29, 95% CI 0.10 to 0.86, three studies, 2388 women). The proportional reductions were similar for countries with low and

To compare the difference in risks of neonatal and maternal complications, including uterine rupture, in a second birth following a planned caesarean section versus emergency caesarean section in the first birth. Prospective cohort study. Population-based cohort in the Netherlands. Linked data set of outcomes for term caesarean section in a first birth followed by a consecutive delivery. We conducted a prospective cohort analysis using data from the Dutch Perinatal Registry. We included primiparous women who gave birth to term singleton infants through planned or emergency caesarean from January 2000 through December 2007, and who had a second singleton delivery during the same period (n = 41,109). Odds ratios and adjusted odds ratios were calculated. Maternal and neonatal complications, specifically uterine rupture, in second births associated with planned and emergency caesareans in the first birth. Women with a history of a planned caesarean section in the first birth (n = 11,445) had a 0.24% risk for uterine rupture, compared with a 0.16% risk for women with a history of emergency caesarean section (n = 29,664; aOR 1.4, 95% CI 0.8-2.4). In multivariate logistic regression, women with planned caesareans in a first birth had a significantly increased risk of stillbirth (aOR 1.5, 95% CI 1.0-2.2) and postpartum haemorrhage (aOR 1.1, 95% CI 1.0-1.2) in second births, compared with women with emergency caesareans in the first birth. We found a moderately increased risk of postpartum haemorrhage and a small to moderately increased risk of uterine rupture and stillbirth as a long-term effect of prior planned caesarean delivery on second births. © 2013 Royal College of Obstetricians and Gynaecologists.

The choice of the type of abdominal incision performed in caesarean delivery is made chiefly on the basis of the individual surgeon's experience and preference. A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: "acute pain", "chronic pain", "Pfannenstiel incision", "Misgav-Ladach", "Joel Cohen incision", in combination with "Caesarean Section", "abdominal incision", "numbness", "neuropathic pain" and "nerve entrapment". Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

To describe the frequency of caesarean sections in a large sample of pedigree dogs in the UK. Data on the numbers of litters born in the previous 10 years were available from a cross-sectional study of dogs belonging to breed club members (2004 Kennel Club/BSAVA Scientific Committee Purebred Dog Health Survey). In this survey 151 breeds were represented with data for households that had reported on at least 10 litters (range 10-14,15): this represented 13,141 bitches which had whelped 22,005 litters. The frequency of caesarean sections was estimated as the percentage of litters that were reported to be born by caesarean section (caesarean rates) and are reported by breed. The dogs were categorised into brachycephalic, mesocephalic and dolicocephalic breeds. The 10 breeds with the highest caesarean rates were the Boston terrier, bulldog, French bulldog, mastiff, Scottish terrier, miniature bull terrier, German wirehaired pointer, Clumber spaniel, Pekingese and Dandie Dinmont terrier. In the Boston terrier, bulldog and French bulldog, the rate was > 80%. These data provide evidence for the need to monitor caesarean rates in certain breeds of dog.

The optimal technique for performing caesarean section with respect to minimising postoperative adhesions has not been determined. To evaluate adhesion formation for three common caesarean section techniques in women undergoing repeat caesarean section surgeries. A database was constructed from Medline, EMBASE, Cochrane Library, National Science Digital Library, China Biological Medicine Database and through contact with experts in this field from January 1990 to May 2010. Studies were included if they examined adhesion formation in repeat caesarean sections as a primary objective, delineated a clear study design, specified an adhesion scoring system, and had sufficient patient exclusion criteria. We abstracted data regarding adhesion formation. The Mantel-Haenszel random-effects model was employed for all analyses using odds ratio or inverse variance, along with 95% CI. Thirty-three qualified studies including 4423 women were analysed. There were 406 adhesions among 571 women and 238 adhesions among 596 women in the Stark's caesarean section (also known as Misgav-Ladach method) group and modified Stark's caesarean section group, respectively, with pooled OR 4.69 (95% CI 3.32-6.62; P < 0.01, 12 studies); 1173 adhesions among 1555 women and 1179 adhesions among 1625 women in Stark's caesarean section group and classic lower-segment caesarean section group, respectively, with pooled odds ratio 1.28 (95% CI 0.97-1.68; P = 0.08, 21 studies); and 29 adhesions from 102 women and 115 adhesions from 193 women in modified Stark's caesarean section group and classic lower-segment caesarean section group, respectively, with pooled odds ratio 0.28 (95% CI 0.10-0.82; P = 0.02, two studies). Closure of the peritoneum in modified Stark's caesarean section resulted in less adhesion formation and should be recommended. © 2010 The Authors Journal compilation © RCOG 2010 BJOG An International Journal of Obstetrics and Gynaecology.

Chronic wounds (ie, wounds that fail to progress through a normal, orderly, timely sequence of repair) continue to pose significant clinical and economic burdens. A prospective, descriptive, 3-week post-marketing surveillance study was conducted across 3 wound care centers in the United States to evaluate the effectiveness of a collagen calcium alginate dressing on chronic wounds in conjunction with standard care (SC) practices (eg, offloading, debridement, compression) to support healing. Eligible participants had to be >18 years of age, have at least 1 chronic wound, and no known sensitivity to collagen. Demographic characteristics were recorded at the screening visit on case report forms. At each visit, wound-related pain was assessed using the Visual Analog Scale along with wound characteristics including size (using digital planimetry), wound exudate (minimal, moderate, heavy), and odor (none, mild). Participants were monitored for adverse events as well as infection based on signs and symptoms in and around the local wound bed, the deeper structures, and the surrounding skin. An intention-to-treat approach was used for all analyses. If an observation was missing, the last observation carried forward principle was used. For wounds that healed, pain and exudate were set to 0 (no pain/exudate) at visit 4. Descriptive, paired t tests and the Wilcoxon signed rank test were used to analyze the data. Of the 31 participants (15 men, 16 women, mean age 66.6 years), most (13, 42%) had a diabetic foot ulcer or venous leg ulcer (10, 32%); median duration of all wounds was 148 days. Thirty (30) patients completed the study. The mean number of comorbidities was 10.6 ± 6.3, and patients used a mean of 9.3 ± 5.64 prescription or over-the-counter medications. For all wounds combined, mean wound area was 4.8 ± 8.38 cm2 at baseline. At week 3, a decrease in wound area of 38.1% was noted (median: 45% ± 42.54; P = .006); 3 wounds healed completely.

Objective To assess the quality and comprehensiveness of the information on caesarean section provided in Brazilian women’s magazines. Design Review of articles published during 1988-2008 in top selling women’s magazines. Setting Brazil, one of the countries with the highest caesarean section rates in the world. Data sources Women’s magazines with the largest distribution during the study period, identified through the official national media indexing organisations. Selection criteria Articles with objective scientific information or advice, comments, opinions, or the experience of ordinary women or celebrities on delivery by caesarean section. Main outcome measures Sources of information mentioned by the author of the article, the accuracy and completeness of data presented on caesarean section, and alleged reasons why women would prefer to deliver though caesarean section. Results 118 articles were included. The main cited sources of information were health professionals (78% (n=92) of the articles). 71% (n=84) of the articles reported at least one benefit of caesarean section, and 82% (n=97) reported at least one short term maternal risk of caesarean section. The benefits most often attributed to delivery by caesarean section were reduction of pain and convenience for family or health professionals. The most frequently reported short term maternal risks of caesarean section were increased time to recover and that it is a less natural way of giving birth. Only one third of the articles mentioned any long term maternal risks or perinatal complications associated with caesarean section. Fear of pain was the main reported reason why women would prefer to deliver by caesarean section. Conclusions Most of the articles published in Brazilian women’s magazines do not use optimal sources of information. The portrayal of caesarean section is mostly balanced, not explicitly in favour of one or another route of delivery, but incomplete and may be leading women to

To assess the mode of delivery and Caesarean Section (CS) rate after successful External Cephalic Version (ECV). A matched case-control study. Data were gathered from a tertiary care university hospital register from 1996-2015. All pregnant women who delivered after successful External Cephalic Version (ECV). Among 643 women who attempted ECV, we identified 198 with successful ECVs and compared them with the next two women who presented for labor management with spontaneous cephalic presentation, matching for delivery date, maternal age, parity, body mass index, and delivery history using univariate and stepwise logistic regression. The main outcome measure was the risk of caesarean. The caesarean section rate was higher after successful ECV (respectively 20.7% versus 7.07%, P<0.05). Caesarean section for abnormal fetal head position (forehead, bregma, face) was higher after successful ECV (28.6% versus 0%). After adjustment for matching and confounding variables (variation of the caesarean section rate over the study period, gestational maternal complications, antepartum fetal complications, term of delivery, induction of labor, oxytocin use for dystocia, neonatal cephalic perimeter), a successful ECV increased the risk of caesarean section (adjusted OR 3.17, 95% CI 1.86-5.46). By stratifying on week, a trend for increased risk for caesarean section was observed at the week after ECV and at post term (28.6% before 37+6, 14.8% at 38+0-38+6, 13.8% at 39+0-39+6, 14.2% at 40+0-40+6 and 33.3% beyond 41+0 weeks' gestation, P=0.06). Women who have a successful ECV are at increased risk of caesarean section compared with women who experience spontaneous cephalic presentation. Copyright © 2017 Elsevier Masson SAS.

To examine the trends in the relationship between caesarean section rates in South Korea and its correlates. Five rounds (1988, 1991, 1994, 1997 and 2000) of population-based National Fertility and Family Health Survey of South Korea. South Korea. Sample Mothers (N= 9184) aged 15-44 years. Caesarean rates were calculated according to correlates and then directly adjusted to five-year age and parity groups. Distribution of all samples (9184 mothers) was standard, producing age- and parity-adjusted caesarean rates. Linear trends of correlates with caesarean rates were examined for ordinal variables such as education, income, urbanisation level (area of residence) and level of prenatal visits. Age- and parity-adjusted caesarean section rates. As caesarean rates rose by year, the relationship of caesarean section with education, occupation and area of residence has been reversed. Associations between caesarean rates, income level, place of delivery and level of prenatal visit were found in 1988 but disappeared by 2000. In 2000, relatively low caesarean rates were found in variables that will be more prevalent in the future, such as higher maternal education, higher maternal occupation and residence in big cities. Caesarean rates may have reached a plateau in South Korea. No maternal or health service factors were detected to further increase the proportion of caesarean deliveries.

To establish the degree of variation across hospitals in the use of Caesarean delivery for the indication of labour dystocia before and after accounting for maternal, fetal, and hospital characteristics. This study was a retrospective, population-based cohort study of nulliparous women delivering term singletons in cephalic position following labour. Delivery visits were extracted from three provincial perinatal registries in the Canadian provinces of Ontario, Alberta, and British Columbia, from 2008-2012. Crude hospital-specific rates of Caesarean delivery for labour dystocia were reported, and these rates were then stabilized to account for hospitals with low delivery volumes. Rates were then adjusted for maternal, fetal, and hospital characteristics using hierarchical logistic regression. Among 403 205 women delivering at 170 hospitals, the overall Caesarean delivery rate was 21.0%, and the rate of Caesarean delivery for labour dystocia was 12.7%, indicating that 60% of all Caesarean deliveries were performed in part for this indication. The middle 95% of hospitals had Caesarean delivery rates for labour dystocia ranging from 4.5% to 24.7%. Differences in maternal case mix and hospital characteristics explained only a small proportion of this variation (95% central range 6.3%-21.7%). Considerable inter-hospital variation in rates of Caesarean delivery for labour dystocia remained after accounting for differences in maternal and hospital factors. Reporting systems that monitor variation in inter-institutional rates should incorporate stabilization and adjustment for case-mix differences and consider indication-specific rates of Caesarean delivery to more fairly compare hospital performance and better target interventions to reduce Caesarean delivery for specific indications.

Gunshot wounds (GSW) to the spine represent a major health concern within today's society. Our study assessed the epidemiologic characteristics of patients with GSW to the spine treated in New Orleans. A retrospective chart review was performed from January 2007 through November 2011 on all the patients who were seen in the emergency room and diagnosed with a gunshot wound to the spine. Epidemiologic factors, as well as the results of admission toxicology screening, were noted. Outcome analysis was performed on patients undergoing conservative versus operative management for their injuries. Clinical outcomes were assessed using the ASIA classification system. Complications related to initial injury, neurosurgical procedures, and hospital stay were noted. A total of 147 patients were enrolled. Of those diagnosed with a GSW to the spine, 88 (59.8%) received an admission toxicology screen. Seventy-three (83%) patients out of those tested had a positive screen, with the most common substances detected being cannabis, cocaine, and alcohol. In regards to management, 127 (87%) patients were treated conservatively and only one (0.7%) patient improved clinically from ASIA D to E. Of the 20 patients who underwent surgery, one (5%) patient had clinical improvement post-operatively from ASIA C to D. This study evaluates the largest number of patients with GSW to the spine per year treated in a single centre, illustrating the violent nature of New Orleans. In this urban population, there was a clear correlation between drug use and suffering a GSW to the spine. Surgical intervention was seldom indicated in these patients and was predominately used for fixation of unstable fractures and decompression of compressive injuries, particularly below T11. Minimally invasive techniques were used successfully at our institution to minimize the risk of post-operative CSF leak. Copyright © 2013 Elsevier Ltd. All rights reserved.

To analyse on a comparative basis the incidence of caesarean sections among the different health care systems in Uruguay and with respect to the World Health Organization's (WHO) standards, taking into account the medical-obstetric characteristics of the births, particularly, the Robson classification. We examine 190,847 births registered by the Perinatal Information System in Uruguay between 2009 and 2014 by type of health care system. Using logit models, we analyse the probability of caesarean section taking into account the Robson classification, other risk factors and the mothers' characteristics. We compared the caesarean rates predicted by the different subsystems for a common population. Furthermore, we contrast the caesarean rates observed in each subsystem with the rates that resulted if the Uruguayan hospitals followed the guidelines of the sample of WHO reference hospitals. Private health systems in Uruguay exhibit a much higher incidence of caesarean sections than public ones, even after considering the medical-obstetric characteristics of the births. Caesarean rates are more than 75% higher than those observed if the WHO standards are applied. Uruguay has a very high incidence of caesarean sections with respect to WHO standards, particularly, in the private sector. This fact is unrelated to the clinical characteristics of the births.

A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: “acute pain”, “chronic pain”, “Pfannenstiel incision”, “Misgav-Ladach”, “Joel Cohen incision”, in combination with “Caesarean Section”, “abdominal incision”, “numbness”, “neuropathic pain” and “nerve entrapment”. Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

Caesarean section is thought to be a risk factor for childhood asthma, but this association may be caused by confounding from, for instance, familial factors. To address this problem, we used twin pairs to assess the risk of childhood asthma after emergency caesarean section. The study was a register-based nation-wide matched cohort study using twin pairs to minimise residual confounding. Included were twin pairs in which the first twin was delivered vaginally and the second by emergency caesarean section during the study period from January 1997 through December 2012. In total, 464 twin pairs (928 twins) were included. In 30 pairs, the first twin (vaginal delivery) was diagnosed with asthma, but the second twin (emergency caesarean section) was not. In 20 pairs, the second twin (emergency caesarean section) was diagnosed with asthma, but the first twin (vaginal delivery) was not. In 11 pairs, both twins developed asthma. In the unadjusted analysis, emergency caesarean section did not affect the risk of asthma (odds ratio = 0.67 (95% confidence interval: 0.38-1.17); p = 0.16). After adjusting for birth weight, gender, umbilical cord pH, Apgar score at 5 min. and neonatal respiratory morbidity, the risk of childhood asthma following emergency caesarean section remained unchanged. Emergency caesarean section was not associated with childhood asthma. none. not relevant.

Oxytocin for labour and caesarean delivery: implications for the anaesthesiologist.

PubMed

Dyer, Robert A; Butwick, Alexander J; Carvalho, Brendan

2011-06-01

The implications of the obstetric use of oxytocin for obstetric anaesthesia practice are summarised. The review focuses on recent research on the uterotonic effects of oxytocin for prophylaxis and management of uterine atony during caesarean delivery. Oxytocin remains the first-line agent in the prevention and management of uterine atony. In-vitro and in-vivo studies show that prior exposure to oxytocin induces uterine muscle oxytocin receptor desensitization. This may influence oxytocin dosing for adequate uterine tone following delivery. Oxytocin has important cardiovascular side-effects (hypotension, tachycardia and myocardial ischaemia). Recent studies suggest that the effective dose of oxytocin for prophylaxis against uterine atony during caesarean delivery is significantly lower than the 5-10 IU historically used by anaesthesiologists. Slow administration of small bolus doses of oxytocin minimises maternal haemodynamic disturbance. Continuous oxytocin infusions are recommended for maintaining uterine tone after bolus administration, although ideal infusion rates are still to be established. The efficacy of the long-acting oxytocin analogue carbetocin requires further investigation. Recommendations are presented for oxytocin dosing during caesarean delivery. Oxytocin remains the first-line uterotonic after vaginal and caesarean delivery. Recent research elucidates the therapeutic range of oxytocin during caesarean delivery, as well as receptor desensitization. Evidenced-based protocols for the prevention and treatment of uterine atony during caesarean delivery are recommended.

Bupivacaine is a commonly used local anaesthetic for spinal anaesthesia for caesarean section, but may produce prolonged motor block, delaying discharge from the post-anaesthesia care unit. Ropivacaine may have a shorter time to recovery of motor function compared with bupivacaine. We performed a meta-analysis to assess the time difference in duration of motor block with intrathecal ropivacaine compared with bupivacaine for caesarean section. We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials databases for randomised controlled trials comparing ropivacaine with bupivacaine in parturients undergoing elective caesarean section under spinal anaesthesia. The primary outcome was the duration of motor block. Secondary outcomes included the time to onset of sensory block, need for conversion to general anaesthesia and the incidence of hypotension. Thirteen trials comprising 743 spinal anaesthetics were included. Intrathecal ropivacaine resulted in a reduced duration of motor block, regressing 35.7min earlier compared with intrathecal bupivacaine (P<0.00001). There was no difference in the time to onset of sensory block (P=0.25) or the incidence of hypotension (P=0.10). Limited data suggested no difference in the rate of conversion to general anaesthesia, but an earlier request for postoperative analgesia with ropivacaine. Compared with bupivacaine, intrathecal ropivacaine is associated with more rapid recovery of motor block despite similar sensory properties and no increased rate of conversion to general anaesthesia. This may be useful in centres in which recovery of motor block is a criterion for discharge from the post-anaesthesia care unit. However, small numbers of trials and significant heterogeneity limit the interpretation of our results. Copyright © 2016 Elsevier Ltd. All rights reserved.

WHO Global Survey on Maternal and Perinatal Health in Latin America: classifying caesarean sections

PubMed Central

2009-01-01

Background Caesarean section rates continue to increase worldwide with uncertain medical consequences. Auditing and analysing caesarean section rates and other perinatal outcomes in a reliable and continuous manner is critical for understanding reasons caesarean section changes over time. Methods We analyzed data on 97,095 women delivering in 120 facilities in 8 countries, collected as part of the 2004-2005 Global Survey on Maternal and Perinatal Health in Latin America. The objective of this analysis was to test if the "10-group" or "Robson" classification could help identify which groups of women are contributing most to the high caesarean section rates in Latin America, and if it could provide information useful for health care providers in monitoring and planning effective actions to reduce these rates. Results The overall rate of caesarean section was 35.4%. Women with single cephalic pregnancy at term without previous caesarean section who entered into labour spontaneously (groups 1 and 3) represented 60% of the total obstetric population. Although women with a term singleton cephalic pregnancy with a previous caesarean section (group 5) represented only 11.4% of the obstetric population, this group was the largest contributor to the overall caesarean section rate (26.7% of all the caesarean sections). The second and third largest contributors to the overall caesarean section rate were nulliparous women with single cephalic pregnancy at term either in spontaneous labour (group 1) or induced or delivered by caesarean section before labour (group 2), which were responsible for 18.3% and 15.3% of all caesarean deliveries, respectively. Conclusion The 10-group classification could be easily applied to a multicountry dataset without problems of inconsistencies or misclassification. Specific groups of women were clearly identified as the main contributors to the overall caesarean section rate. This classification could help health care providers to plan practical

While opioids are the mainstay for post-operative analgesia after lower segment caesarean section, they are associated with various untoward effects. Ultrasound guided transversus abdominis plane (TAP) block has been postulated to provide effective analgesia for caesarean section. We evaluated the analgesic efficacy of this block for post caesarean analgesia in a randomised controlled trial. One hundred thirty-nine mothers undergoing caesarean delivery were randomised to receive TAP block with either 20 ml 0.375% ropivacaine or 20 ml saline after obtaining informed consent. All the subjects received a standard spinal anaesthetic and diclofenac was administered for post-operative pain. Breakthrough pain was treated with tramadol. Post-operatively, all the subjects were assessed at 0, 2, 4, 6, 8, 10, 12, 18 & 24 h. The primary outcome was the time to first analgesic request. The secondary measures of outcome were pain, nausea, sedation, number of doses of tramadol administered and satisfaction with the pain management. The median (interquartile range) time to first analgesic request was prolonged in the TAP group compared to the control group (p < 0.0001); 11 h (8,12) and 4 h (2.5,6) respectively. The median (interquartile range) number of doses of tramadol consumed in the TAP group was 0 (0,1) compared to 2 (1,2) in the control group (p < 0.0001). At all points in the study, pain scores both at rest and on movement were lower in the study group (p < 0.0001). Maternal satisfaction with pain relief was also higher in the study group (p 0.0002). One subject in the TAP group had convulsions following injection of local anaesthetic solution. She was managed conservatively with supportive treatment following which she recovered. TAP block reduces pain, prolongs the duration of analgesia and decreases supplemental opioid consumption when used for multimodal analgesia for pain relief after caesarean section. However, the risk of local anaesthetic systemic

Caesarean section increases the risk of postpartum infection for women and prophylactic antibiotics have been shown to reduce the incidence; however, there are adverse effects. It is important to identify the most effective class of antibiotics to use and those with the least adverse effects. To determine, from the best available evidence, the balance of benefits and harms between different classes of antibiotic given prophylactically to women undergoing caesarean section. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2014) and reference lists of retrieved papers. We included randomised controlled trials comparing different classes of prophylactic antibiotics given to women undergoing caesarean section. We excluded trials that compared drugs with placebo or drugs within a specific class; these are assessed in other Cochrane reviews. Two review authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. We included 35 studies of which 31 provided data on 7697 women. For the main comparison between cephalosporins versus penicillins, there were 30 studies of which 27 provided data on 7299 women. There was a lack of good quality data and important outcomes often included only small numbers of women.For the comparison of a single cephalosporin versus a single penicillin (Comparison 1 subgroup 1), we found no significant difference between these classes of antibiotics for our chosen most important seven outcomes namely: maternal sepsis - there were no women with sepsis in the two studies involving 346 women; maternal endometritis (risk ratio (RR) 1.11, 95% confidence interval (CI) 0.81 to 1.52, nine studies, 3130 women, random effects, moderate quality of the evidence); maternal wound infection (RR 0.83, 95% CI 0.38 to 1.81, nine studies, 1497 women, random effects, low quality of the evidence), maternal urinary tract infection (RR 1.48, 95% CI 0.89 to 2.48, seven studies, 1120

As in most countries of the world also at Kosovo the rate of Cesarean section from year to year is increasing. The main purpose of this paper was to present the incidence of births completed by Caesarean section at the Clinic of Gynecology and Obstetrics of University Clinical Center of Kosovo in Prishtinë. This study is retrospective, namely its made by collecting epidemiological data from patients' histories that completed birth by Caesarean section for the period 2000-2006 in this clinic. During this period, 14 maternal deaths were recorded during or after Caesarean section. Besides this, 14 lethal outcomes, the object of our study was 84 mothers which completed birth by Caesarean section and which are best used as a control group. The average age of mothers who died during or after Caesarean section was 32.1 years (SD ± 4.9). Youngest in this group was 24 years old and oldest 42 years. While the average age of mothers from the control group was 30.6 years (SD ± 5.9). Youngest was 19 and oldest 43 years, without significant difference. Most mothers included in the survey had more than one indication for Caesarean section. The most frequent indication was PIH syndrome with 33.7% and previous Caesarean section in 32.7%. Then with the participation of 12.2% were abruption of the placenta and disproportio feto pelvinea, 11.2% pelvinea and placenta praevia presentation, 10.2% parturiens while other indications were much rarer with less than 10% participation. Based on this we can conclude that the risk of the Caesarean section is high.

Perinatal health disparities including disparities in caesarean births have been observed between migrant and non-migrant women and some literature suggests that non-medical factors may be implicated. A systematic review was conducted to determine if migrants in Western industrialized countries consistently have different rates of caesarean than receiving-country-born women and to identify the reasons that explain these differences. Reports were identified by searching 12 literature databases (from inception to January 2012; no language limits) and the web, by bibliographic citation hand-searches and through key informants. Studies that compared caesarean rates between international migrants and non-migrants living in industrialized countries and that did not have a 'fatal flaw' according to the US Preventative Services Task Force criteria were included. Studies were summarized, analyzed descriptively and where possible, meta-analyzed. Seventy-six studies met inclusion criteria. Caesarean rates between migrants and non-migrants differed in 69% of studies. Meta-analyses revealed consistently higher overall caesarean rates for Sub-Saharan African, Somali and South Asian women; higher emergency rates for North African/West Asian and Latin American women; and lower overall rates for Eastern European and Vietnamese women. Evidence to explain the consistently different rates was limited. Frequently postulated risk factors for caesarean included: language/communication barriers, low SES, poor maternal health, GDM/high BMI, feto-pelvic disproportion, and inadequate prenatal care. Suggested protective factors included: a healthy immigrant effect, preference for a vaginal birth, a healthier lifestyle, younger mothers and the use of fewer interventions during childbirth. Certain groups of international migrants consistently have different caesarean rates than receiving-country-born women. There is insufficient evidence to explain the observed differences.

Caesarean birth is one of the most frequently performed major obstetrical interventions. Although there is speculation that caesarean at term may have consequences for children's later health and development, longer-term studies are needed. We aimed to evaluate risks to poor school achievement among children born by caesarean section compared with spontaneous vaginal birth. This population-based observational study involved linkage of routinely collected perinatal data with children's school assessments. Perinatal data included all children born in South Australia from 1999 to 2005. Participants were children born by elective caesarean (exposed, n = 650) or vaginal birth (unexposed, n = 2959), to women who previously had a caesarean delivery. School assessments were reported via a standardised national assessment program for children attending grade three (at ~eight years of age). Assessments included reading, writing, spelling, grammar and numeracy and were categorised according to performing at above or ≤National Minimum Standards (NMS). Statistical analyses involved augmented inverse probability weighting (apiw) and accounted for a range of maternal, perinatal and sociodemographic characteristics. Children performing ≤NMS for vaginal birth versus caesarean section were as follows: reading 144/640 (23%) and 688/2921 (24%), writing 69/636(11%) and 351/2917 (12%), spelling 128/646 (20%) and 684/2937 (23%), grammar 132/646 (20%) and 655/2937 (22%), and numeracy 151/634 (24%) and 729/2922 (25%). Both the raw data and the aipw analyses suggested little differences in school achievement between children born by caesarean versus vaginal birth. Analyses that carefully controlled for a wide range of confounders suggest that caesarean section does not increase the risk of poor school outcomes at age eight. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Caesarean Section in Peru: Analysis of Trends Using the Robson Classification System

2016-01-01

Introduction Cesarean section rates continue to increase worldwide while the reasons appear to be multiple, complex and, in many cases, country specific. Over the last decades, several classification systems for caesarean section have been created and proposed to monitor and compare caesarean section rates in a standardized, reliable, consistent and action-oriented manner with the aim to understand the drivers and contributors of this trend. The aims of the present study were to conduct an analysis in the three Peruvian geographical regions to assess levels and trends of delivery by caesarean section using the Robson classification for caesarean section, identify the groups of women with highest caesarean section rates and assess variation of maternal and perinatal outcomes according to caesarean section levels in each group over time. Material and Methods Data from 549,681 pregnant women included in the Peruvian Perinatal Information System database from 43 maternal facilities in three Peruvian geographical regions from 2000 and 2010 were studied. The data were analyzed using the Robson classification and women were studied in the ten groups in the classification. Cochran-Armitage test was used to evaluate time trends in the rates of caesarean section rates and; logistic regression was used to evaluate risk for each classification. Results The caesarean section rate was 27% and a yearly increase in the overall caesarean section rates from 2000 to 2010 from 23.5% to 30% (time trend p<0.001) was observed. Robson groups 1, 3 (nulliparous and multiparas, respectively, with a single cephalic term pregnancy in spontaneous labour), 5 (multiparas with a previous uterine scar with a single, cephalic, term pregnancy) and 7 (multiparas with a single breech pregnancy with or without previous scars) showed an increase in the caesarean section rates over time. Robson groups 1 and 3 were significantly associated with stillbirths (OR 1.43, CI95% 1.17–1.72; OR 3.53, CI95% 2.95�

This population-based cohort study aimed to investigate the demographic and psychosocial characteristics associated with fear of childbirth and the relative importance of such fear as a predictor of elective caesarean section. A sample of 1789 women from the Akershus Birth Cohort in Norway provided data collected by three self-administered questionnaires at 17 and 32 weeks of pregnancy and 8 weeks postpartum. Information about the participants' childbirths was obtained from the hospital records. Eight percent of the women reported fear of delivery, defined as a score of ≥85 on the Wijma Delivery Expectancy Questionnaire. Using multivariable logistic regression models, a previous negative overall birth experience exerted the strongest impact on fear of childbirth, followed by impaired mental health and poor social support. Fear of childbirth was strongly associated with a preference for elective caesarean section (aOR 4.6, 95% CI 2.9-7.3) whereas the association of fear with performance of caesarean delivery was weaker (aOR 2.4, 95% CI 1.2-4.9). The vast majority (87%) of women with fear of childbirth did not, however, receive a caesarean section. By contrast, a previous negative overall birth experience was highly predictive of elective caesarean section (aOR 8.1, 95% CI 3.9-16.7) and few women without such experiences did request caesarean section. Results suggest that women with fear of childbirth may have identifiable vulnerability characteristics, such as poor mental health and poor social support. Results also emphasize the need to focus on the subjective experience of the birth to prevent fear of childbirth and elective caesarean sections on maternal request. Regarding the relationship with social support, causality has to be interpreted cautiously, as social support was measured at 8 weeks postpartum only.

the rising trends in caesarean section have been partially attributed to women's requests. Many studies in developed and very few in developing countries have attempted to understand this phenomenon. This qualitative study explores experiences of women having caesarean section on demand in a middle-income country with a private health-care system. an inductive qualitative design, using face-to-face semi-structured interviews. women were identified and recruited through a perinatal database and selected obstetricians' clinics in the Greater Beirut area in Lebanon. a purposive sample of women who had a caesarean childbirth within the four months preceding the interview, were visited for an interview at home using a semi-structured interview guide. Thematic content analysis was conducted on a sub-sample of 22 women who requested a caesarean birth. lack of information about caesarean sections fosters women's fear from labour pain and acts as the main impetus for women to consider caesareans as the pain free alternative. Findings reveal health-care providers' role in reinforcing beliefs about caesarean sections being the way for pain free deliveries by overestimating the safety of the procedure and disregarding postpartum health issues. caesarean birth is presented to women as a safe option for 'pain free' childbirth. This needs to be considered within the cultural context of understanding safety and pain as well as the dynamics of power in maternity care. Health-care professionals need to explore these dimensions and promote women's informed choice as well as encouraging the normality of birth. Copyright © 2012 Elsevier Ltd. All rights reserved.

Intravenous ketamine has been used during general and regional anaesthesia for caesarean section. No systematic review and meta-analysis on the desired effects and adverse effects of ketamine administration during caesarean section have yet been performed. After a systematic literature search a meta-analysis was conducted with the random effects model. Weighted mean difference (WMD) or risk ratio and 95% confidence intervals (CIs) were computed. Twelve randomised controlled double-blind trials comprising 953 patients were included: seven studies reported on spinal anaesthesia and five on general anaesthesia. Significant differences in the aforementioned outcome variables were found only in the spinal anaesthesia studies. In the spinal anaesthesia studies the time to the first analgesic request was significantly longer in ketamine-treated women, the WMD was 49.36 min (95% CI 43.31-55.41); visual analogue scale pain scores at rest 2 h after surgery were significantly lower. No differences were observed for maternal nausea, vomiting, pruritus, and psychomimetic effects. Only few data were found for neonatal outcomes. We conclude that ketamine enhances post-operative analgesia after caesarean section under spinal anaesthesia. There is a paucity of data for several maternal adverse effects as well as for neonatal well-being. Further studies are needed for general anaesthesia. © 2015 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

This study aimed to examine the association of social support, social factors, and maternal complications with caesarean deliveries in native and immigrant women, and to explore the association between acculturation and caesarean deliveries in immigrant women in Taiwan. This prospective panel study was conducted from August 2012 through April 2014 and included 222 native and 147 immigrant pregnant women in Taiwan. Caesarean rates did not differ significantly between native and immigrant women, including the overall caesarean rate (28.8%, 32.0%), medically indicated caesarean (22.5%, 24.5%), and caesarean without medical indications (6.3%, 7.5%). Results of multiple logistic regression models revealed that maternal complications and household activity support were positively associated with caesarean deliveries. Both native and immigrant women with high levels of informational support were less likely to receive caesareans. Immigrant women who were older than 35 years, had a middle level socioeconomic status, and perceived a high level of acceptance of caesarean in Taiwan were more likely to have caesarean deliveries. Informational support was a protective factor for caesarean delivery, whereas household activity support offered by the family was positively associated with caesarean delivery. Perceived acceptance level in mainstream society could affect immigrant women's use of caesarean delivery.

Inter-hospital variations in caesarean sections. A risk adjusted comparison in the Valencia public hospitals

BACKGROUND—The aim of this study was to describe the variability in caesarean rates in the public hospitals in the Valencia Region, Spain, and to analyse the association between caesarean sections and clinical and extra-clinical factors.
METHODS—Analysis of data contained in the Minimum Basic Data Set (MBDS) compiled for all births in 11 public hospitals in Valencia during 1994-1995 (n=36 819). Bivariate and multivariate analyses were used to evaluate the association between caesarean section rates and specific risk factors. The multivariate model was used to construct predictions about caesarean rates for each hospital, for comparison with rates observed.
RESULTS—Caesarean rates were 17.6% (inter-hospital range: 14.7% to 25.0%), with ample variability between hospitals in the diagnosis of maternal-fetal risk factors (particularly dystocia and fetal distress), and the indication for caesarean in the presence of these factors. Multivariate analysis showed that maternal-fetal risk factors correlated strongly with caesarean section, although extra-clinical factors, such as the day of the week, also correlated positively. After adjusting for the risk factors, the inter-hospital variation in caesarean rates persisted.
CONCLUSIONS—Although certain limitations (imprecision of some diagnoses and information biases in the MBDS) make it impossible to establish unequivocal conclusions, results show a high degree of variability among hospitals when opting for caesarean section. This variability cannot be justified by differences in obstetric risks.

Rates of caesarean section (CS) have been rising globally. It is important to use the most effective and safe technique. To compare the effects of complete methods of caesarean section; and to summarise the findings of reviews of individual aspects of caesarean section technique. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (August 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 3) and reference lists of identified papers. Randomised controlled trials of intention to perform caesarean section using different techniques. Two review authors independently assessed studies and extracted data. 'Joel-Cohen based' compared with Pfannenstiel CS was associated with: less blood loss, (five trials, 481 women; weighted mean difference (WMD) -64.45 ml; 95% confidence interval (CI) -91.34 to -37.56 ml); shorter operating time (five trials, 581 women; WMD -18.65; 95% CI -24.84 to -12.45 minutes); postoperatively, reduced time to oral intake (five trials, 481 women; WMD -3.92; 95% CI -7.13 to -0.71 hours); less fever (eight trials, 1412 women; relative risk (RR) 0.47; 95% CI 0.28 to 0.81); shorter duration of postoperative pain (two comparisons from one trial, 172 women; WMD -14.18 hours; 95% CI -18.31 to -10.04 hours); fewer analgesic injections (two trials, 151 women; WMD -0.92; 95% CI -1.20 to -0.63); and shorter time from skin incision to birth of the baby (five trials, 575 women; WMD -3.84 minutes; 95% CI -5.41 to -2.27 minutes). Serious complications and blood transfusions were too few for analysis.Misgav-Ladach compared with the traditional method (lower midline abdominal incision) was associated with reduced: blood loss (339 women; WMD -93.00; 95% CI -132.72 to -53.28 ml); operating time (339 women; WMD-7.30; 95% CI -8.32 to -6.28 minutes); time to mobilisation (339 women; WMD -16.06; 95% CI -18.22 to -13.90 hours); and length of postoperative stay for the mother (339 women; WMD -0.82; 95% CI -1.08 to

Recent Advances in Fractional Laser Resurfacing: New Paradigm in Optimal Parameters and Post-Treatment Wound Care

Hsiao, Francis C.; Bock, Gerald N.; Eisen, Daniel B.

2012-01-01

Background Laser plays an increasingly prominent role in skin rejuvenation. The advent of fractional photothermolysis revolutionizes its application. Microcolumns of skin are focally injured, leaving intervening normal skin to facilitate rapid wound healing and orderly tissue remodeling. The Problem Even with the popularity of fractional laser devices, we still have limited knowledge about the ideal treatment parameters and postlaser wound care. Basic/Clinical Science Advances Many clinicians believe that higher microbream energy in fractional laser devices results in better clinical outcome. Two recent studies argue against this assumption. One article demonstrates that lower fluence can induce comparable molecular changes with fewer side effects. Another study corroborates this by showing that lower-density settings produce similar clinical outcome in scar remodeling as higher-density ones, but with fewer side effects. To shed light on the optimal post-treatment wound care regimen from fractional ablative resurfacing, another paper shows that platelet-rich plasma (PRP) can reduce transepidermal water loss and skin color changes within 1 month after treatment. Clinical Care Relevance For fractional nonablative resurfacing, lower settings in fluence or density may produce similar dermal remodeling as higher settings and with a better side-effect profile. Moreover, autologous PRP appears to expedite wound healing after fractional ablative resurfacing. Conclusion Lower microbeam energy in fractional laser resurfacing produces similar molecular changes and clinical outcome with fewer side effects. The findings might portend a shift in the paradigm of treatment parameters. Autologous PRP can facilitate better wound healing, albeit modestly. Long-term follow-ups and larger studies are necessary to confirm these findings. PMID:24527307

The Immediate and Delayed Post-Debridement Effects on Tissue Bacterial Wound Counts of Hypochlorous Acid Versus Saline Irrigation in Chronic Wounds.

Hiebert, John M; Robson, Martin C

2016-01-01

Introduction: Wound debridement is considered essential in chronic wound management. Hypochlorous acid has been shown to be an effective agent in reducing wound bacterial counts in open wounds. Ultrasound-enabled wound debridement is an effective and efficient method of debridement. This study compared ultrasound irrigation with hypochlorous acid versus saline irrigation for wound debridement on pre- and postoperative wounds and determined regrowth of bacteria over 1 week period of time. Finally, the outcome of definitive wound closure of the clinically clean-appearing wounds was recorded. Methods: Seventeen consenting adult patients with chronic open wounds were randomly selected for study. The patients were randomly divided into the hypochlorous acid irrigation or saline irrigation group. All patients provided pre- and postoperative tissue samples for qualitative and quantitative bacteriology. For the time (7 days) between the debridement procedure and the definitive closure procedure, the wounds were dressed with a silver-impregnated dressing and a hydroconductive dressing. Results : Both types of irrigation in the ultrasonic system initially lowered the bacterial counts by 4 to 6 logs. However, by the time of definitive closure, the saline-irrigated wounds had bacterial counts back up to 10 5 whereas the hypochlorous acid-irrigated wounds remained at 10 2 or fewer. More than 80% of patients in the saline group had postoperative closure failure compared with 25% of patients in the hypochlorous acid group. Conclusions: Hypochlorous acid irrigation with ultrasound debridement reduced bacterial growth in chronic open wounds more efficiently than saline alone. Postoperative wound closure outcomes suggest a remarkable reduction in wound complications after wound debridement using hypochlorous acid irrigation with ultrasound versus saline alone.

breast-feeding outcomes are often worse after caesarean section compared to vaginal childbirth. this study characterises mothers' breast-feeding intentions and their infant feeding experiences after caesarean childbirth. data are from 115 mothers on a postnatal unit in Northeast England during February 2006-March 2009. Interviews were conducted an average of 1.5 days (range 1-6 days) after the women underwent unscheduled or scheduled caesarean. thematic analysis of the data suggested was mostly considered the 'right thing to do,' preferable, natural, and 'supposedly healthier,' but tiring and painful. Advantages of supplementation involved more satiated infants, feeding ease, and longer sleep bouts. The need for 'thinking about yourself' was part of caesarean recovery. Infrequent feeding was concerning but also enabled maternal rest. Other breast-feeding obstacles were maternal mobility limitations, positioning difficulties, and frustration at the need for assistance. Participants were confused about nocturnal infant wakings, leading many to determine that they had insufficient milk. Mothers were surprised that sub-clinically poor infant condition was common following caesarean section. Some breast-feeding difficulty stemmed from 'mucus' expulsion that had to occur before the infants could be 'interested' in feeding. Women who cited motivations for breast feeding that included benefit to themselves were more likely to exclusively breast feed on the postnatal unit after their caesareans than those who reported infant-only motivations. for the majority of mothers, breast feeding after a caesarean is affected by interrelated and compounding difficulties. Provision of more relational breast-feeding information may enable families to better anticipate early feeding experiences after caesarean section childbirth. © 2013 Elsevier Ltd.

Postnatally, scars occur as a consequence of cutaneous wound healing. Scarless wound healing is highly desired for patients who have undergone surgery or trauma, especially to exposed areas. Based on the properties of mesenchymal stem cells (MSCs) for tissue repair and immunomodulation, we investigated the potential of MSCs for scarless wound healing. MSCs were expanded from umbilical cord blood (UCB-MSCs) and Wharton's jelly (WJ-MSCs) from healthy donors who underwent elective full-term pregnancy caesarean sections. UCB-MSCs expressed lower levels of the pre-inflammatory cytokines IL1A and IL1B, but higher levels of the extracellular matrix (ECM)-degradation enzymes MMP1 and PLAU compared with WJ-MSCs, suggesting that UCB-MSCs were more likely to favor scarless wound healing. However, we failed to find significant benefits for stem cell therapy in improving wound healing and reducing collagen deposition following the direct injection of 1.0 × 10(5) UCB-MSCs and WJ-MSCs into 5 mm full-thickness skin defect sites in nude mice. Interestingly, the implantation of UCB-MSCs tended to increase the expression of MMP2 and PLAU, two proteases involved in degradation of the extracellular matrix in the wound tissues. Based on our data, UCB-MSCs are more likely to be a favorable potential stem cell source for scarless wound healing, although a better experimental model is required for confirmation.

Birth cohort studies in some countries have shown a link between caesarean section and asthma. To determine if there is an association between asthma and delivery via caesarean section in Malaysian children. This is a case-control study involving 156 children aged 3-15 years old, in a tertiary hospital in Kuala Lumpur, Malaysia. Seventy-eight children with a confirmed diagnosis of asthma and seventy-eight age-matched controls (no history of asthma or wheezing) were enrolled. Demographic data including mode of delivery and family history of allergic disorders was obtained. Total serum immunoglobulin E (IgE) was measured and skin prick tests (SPT) to 6 common aeroallergens were performed. The median age of the patients was 8 years old. One hundred and three (66%) children were delivered via normal vaginal delivery, 8 (5.1%) via assisted vaginal delivery and 45 children (28.9%) via caesarean section. Delivery via caesarean section was not significantly associated with asthma (OR = 1.21 [95% CI 0.60-2.41], p = 0.596). Children delivered via caesarean section did not have higher IgE levels nor were they more sensitized to aeroallergens. Multiple logistic regression showed that asthma was significantly associated with a positive family history of atopy (OR = 13.8 [95% CI 5.96, 32.1], p < 0.001). Introduction of semi-solid food after 6 months old had a protective effect against asthma (OR = 0.97 [95% CI 0.94, 0.99], p = 0.034). Childhood asthma in Malaysian children was not associated with delivery by caesarean section.

Vaginal delivery after previous caesarean section: is X-ray pelvimetry necessary?

To determine whether antepartum X-ray pelvimetry (XRP) reliably identified women suitable for a trial labour or repeat elective caesarean section after one previous section. A prospective controlled trial in which women were randomly allocated to either an antepartum XRP group who had XRP at 36 weeks gestation to determine mode of delivery, or a control group who had a trial labour without antepartum XRP. Following delivery, all controls had postpartum XRP. Department of Obstetrics and Gynaecology, King Edward VIII Hospital, Durban, South Africa. Three hundred-six women with a history of one previous caesarean section. Mode of delivery, birthweight and maternal and perinatal mortality and morbidity in the two groups. In the antepartum XRP group, 23 of 144 (16%) of women delivered vaginally compared with 60 of 144 (42%) controls (P < 0.0001). Of the 84 women with adequate antepartum XRP only 23 (27.7%) delivered vaginally. In the control group, 33 of 60 (55%) women who had vaginal deliveries had inadequate postpartum XRP and would have had a caesarean section if this information was known in the antepartum period; 62 of 84 (74%) caesarean sections in the control group had adequate postpartum XRP. Birthweight of the infants was similar in the two groups. There were no maternal or perinatal deaths. Maternal morbidity was similar in the two groups. Neonatal morbidity was minimal. Antepartum XRP is not necessary prior to a trial labour in women with one previous caesarean section. It increases the caesarean section rate and is a poor predictor of the outcome of labour.

Objective To assess the risks and benefits associated with caesarean delivery compared with vaginal delivery. Design Prospective cohort study within the 2005 WHO global survey on maternal and perinatal health. Setting 410 health facilities in 24 areas in eight randomly selected Latin American countries; 123 were randomly selected and 120 participated and provided data Participants 106 546 deliveries reported during the three month study period, with data available for 97 095 (91% coverage). Main outcome measures Maternal, fetal, and neonatal morbidity and mortality associated with intrapartum or elective caesarean delivery, adjusted for clinical, demographic, pregnancy, and institutional characteristics. Results Women undergoing caesarean delivery had an increased risk of severe maternal morbidity compared with women undergoing vaginal delivery (odds ratio 2.0 (95% confidence interval 1.6 to 2.5) for intrapartum caesarean and 2.3 (1.7 to 3.1) for elective caesarean). The risk of antibiotic treatment after delivery for women having either type of caesarean was five times that of women having vaginal deliveries. With cephalic presentation, there was a trend towards a reduced odds ratio for fetal death with elective caesarean, after adjustment for possible confounding variables and gestational age (0.7, 0.4 to 1.0). With breech presentation, caesarean delivery had a large protective effect for fetal death. With cephalic presentation, however, independent of possible confounding variables and gestational age, intrapartum and elective caesarean increased the risk for a stay of seven or more days in neonatal intensive care (2.1 (1.8 to 2.6) and 1.9 (1.6 to 2.3), respectively) and the risk of neonatal mortality up to hospital discharge (1.7 (1.3 to 2.2) and 1.9 (1.5 to 2.6), respectively), which remained higher even after exclusion of all caesarean deliveries for fetal distress. Such increased risk was not seen for breech presentation. Lack of labour was a risk factor

Background Although advances in the reduction of maternal mortality have been made, up to 273,000 women will die this year from obstetric etiologies. Obstructed labor (OL), most commonly treated with Caesarean delivery, has been identified as a major contributor to global maternal morbidity and mortality. We used economic and epidemiological modeling to estimate the cost per disability-adjusted life-year (DALY) averted and benefit-cost ratio of treating OL with Caesarean delivery for 49 countries identified as providing an insufficient number of Caesarean deliveries to meet demand. Methods and Findings Using publicly available data and explicit economic assumptions, we estimated that the cost per DALY (3,0,0) averted for providing Caesarean delivery for OL ranged widely, from $251 per DALY averted in Madagascar to $3,462 in Oman. The median cost per DALY averted was $304. Benefit-cost ratios also varied, from 0.6 in Zimbabwe to 69.9 in Gabon. The median benefit-cost ratio calculated was 6.0. The main limitation of this study is an assumption that lack of surgical capacity is the main factor responsible for DALYs from OL. Conclusions Using the World Health Organization's cost-effectiveness standards, investing in Caesarean delivery can be considered “highly cost-effective” for 48 of the 49 countries included in this study. Furthermore, in 46 of the 49 included countries, the benefit-cost ratio was greater than 1.0, implying that investment in Caesarean delivery is a viable economic proposition. While Caesarean delivery alone is not sufficient for combating OL, it is necessary, cost-effective by WHO standards, and ultimately economically favorable in the vast majority of countries included in this study.

Summary Background Results from case-control studies have shown an increased risk of acute lymphoblastic leukaemia (ALL) in young children born by caesarean delivery, and prelabour caesarean delivery in particular; however, an association of method of delivery with childhood leukaemia subtypes has yet to be established. We therefore did a pooled analysis of data to investigate the association between childhood leukaemia and caesarean delivery. Methods We pooled data from 13 case-control studies from the Childhood Leukemia International Consortium done in nine countries (Canada, Costa Rica, Egypt, France, Germany, Greece, Italy, New Zealand, and the USA) for births from 1970-2013. We analysed caesarean delivery overall and by indications that probably resulted in prelabour caesarean delivery or emergency caesarean delivery. We used multivariable logistic regression models, adjusted for child's birthweight, sex, age, ethnic origin, parental education, maternal age, and study, to estimate odds ratios (ORs) and 95% CIs for the risk of ALL and acute myeloid leukaemia (AML) in children aged 0-14 years at diagnosis. Findings The studies provided data for 8780 ALL cases, 1332 AML cases, and 23 459 controls, of which the birth delivery method was known for 8655 (99%) ALL cases, 1292 (97%) AML cases, and 23 351 (>99%) controls. Indications for caesarean delivery were available in four studies (there were caesarean deliveries for 1061 of 4313 ALL cases, 138 of 664 AML cases, and 1401 of 5884 controls). The OR for all indications of caesarean delivery and ALL was 1.06 (95% CI 0.99–1.13), and was significant for prelabour caesarean delivery and ALL (1.23 [1.04-1.47]; p=0.018). Emergency caesarean delivery was not associated with ALL (OR 1.02 [95% CI 0.81-1.30]). AML was not associated with caesarean delivery (all indications OR 0.99 [95% CI 0.84-1.17]; prelabour caesarean delivery 0.83 [0.54-1.26]; and emergency caesarean delivery 1.05 [0.63-1.77]).

Wound healing is a highly orchestrated process and involves a wide variety of cellular components, chemokines and growth factors. Laser irradiation has influenced gene expression and release of various growth factors, cytokines and extracellular matrix proteins involved in wound healing. This study aimed to determine the expression profile of genes involved in wound healing in wounded and diabetic wounded fibroblast cells in response to irradiation at a wavelength of 660 nm. Human skin fibroblast cells (WS1) were irradiated with a diode laser (wavelength 660 nm; fluence 5 J/cm2; power output 100 mW; power density 11 mW/cm2; spot size 9.1 cm2; exposure duration 7 min 35 s). Total RNA was isolated and 1 μg reverse transcribed into cDNA which was used as a template in real-time qualitative polymerase chain reaction (qPCR). Eighty four genes involved in wound healing (extracellular matrix and cell adhesion; inflammatory cytokines and chemokines; growth factors; and signal transduction) were evaluated in wounded and diabetic wounded cell models. Forty eight hours post-irradiation, 6 genes were significantly upregulated and 8 genes were down-regulated in irradiated wounded cells, whereas 1 gene was up-regulated and 33 genes down-regulated in irradiated diabetic wounded cells. Irradiation of stressed fibroblast cells to a wavelength of 660 nm and a fluence of 5 J/cm2 modulated the expression of different genes involved in wound healing in different cell models. Modulation of these genes leads to the effects of laser irradiation seen both in vivo and in vitro, and facilitates the wound healing process.

Pregnancy in women with achondroplasia presents major challenges for anaesthetists and obstetricians. We report the case of a woman with achondroplasia who underwent general anaesthesia for an elective caesarean section. She was 99cm in height and her condition was further complicated by severe kyphoscoliosis and previous back surgery. She was reviewed in the first trimester at the anaesthetic high-risk clinic. A multidisciplinary team was convened to plan her peripartum care. Because of increasing dyspnoea caesarean section was performed at 32weeks of gestation. She received a general anaesthetic using a modified rapid-sequence technique with remifentanil and rocuronium. The intraoperative period was complicated by desaturation and high airway pressures. The woman's postoperative care was complicated by respiratory compromise requiring high dependency care. Copyright © 2014 Elsevier Ltd. All rights reserved.

Arginase plays important regulatory roles in polyamine, ornithine, and nitric oxide syntheses. However, its role in the healing process has not been delineated. In this study, we used a highly potent and specific inhibitor of arginase, namely 2(S)-amino-6-boronohexanoic acid NH4 (ABH) to evaluate the role of arginase function in wound healing. ABH or saline was applied topically to full thickness, dorsal, excisional wounds in C57BL/6 mice every 8 hours for 14 days post surgery and the rate of wound closure was estimated planimetrically. Wound tissue was harvested from mice sacrificed on postoperative days 3 and 7 and examined histologically. The extent of epithelial, connective, and granulation tissue present within the wound area was estimated histomorphometrically. The effect of ABH on wound arginase activity, production of nitric oxide metabolites (NO(x)), and presence of smooth muscle actin positive cells (myofibroblasts) was evaluated. While arginase activity was inhibited in vivo, the rate of wound closure significantly increased 7 days post-surgery, (21 ± 4%: P < .01; Student t test) in ABH treated animals. This was accompanied by an early increase in wound granulation tissue and accumulation of NO(x) followed by enhanced re-epithelialization and localization of myofibroblasts beneath the wound epithelium. Arginase inhibition improves excisional wound healing and may be used to develop therapeutics for early wound closure. Copyright © 2012 Mosby, Inc. All rights reserved.

Risk factors for post-cesarean wound infection, but not disruption, are well-described in the literature. The primary objective of this study was to identify risk factors for non-infectious post-cesarean wound disruption. Secondary analysis was conducted using data from a single-center randomized controlled trial of staple versus suture skin closure in women ≥24 weeks' gestation undergoing cesarean delivery. Wound disruption was defined as subcutaneous skin or fascial dehiscence excluding primary wound infections. Composite wound morbidity (disruption or infection) was examined as a secondary outcome. Patient demographics, medical co-morbidities, and intrapartum characteristics were evaluated as potential risk factors using multivariable logistic regression. Of the 398 randomized patients, 340, including 26 with disruptions (7.6%) met inclusion criteria and were analyzed. After multivariable adjustments, African-American race (aOR 3.9, 95% CI 1.1-13.8) and staple - as opposed to suture - wound closure (aOR 5.4, 95% CI 1.8-16.1) remained significant risk factors for disruption; non-significant increases were observed for body mass index ≥30 (aOR 2.1, 95% CI 0.6-7.5), but not for diabetes mellitus (aOR 0.9, 95% CI 0.3-2.9). RESULTS for composite wound morbidity were similar. Skin closure with staples, African-American race, and considering the relatively small sample size, potentially obesity are associated with increased risk of non-infectious post-cesarean wound disruption.

To evaluate the quality of anaesthesia for Caesarean sections at Muhimbili National Hospital, Dar es Salaam, Tanzania. We developed an instrument consisting of 40 quality indicators using an expert group process based on the existing literature. Using the instrument, we observed 50 Caesarean sections. Twenty-eight of the indicators were structural indicators, such as essential drugs, oxygen supply and anaesthetic equipment. Twelve were process indicators such as evaluation of airway, blood pressure assessment or insertion of an intravenous line. The median patient age was 28.5 years. A total of 75% (range 61-82%) of the structural indicators were present in the operating theatres, and 55% (range 33-83%) of the process indicators were performed. The neonates' median Apgar score was 9 (range 3-10). Seven babies required ventilation, four babies were stillborn, and all others were alive at follow-up 2 days after partus. All mothers were alive 2 days post-surgery. The low process score suggests that quality improvement initiatives should focus on the processes of anaesthesia for Caesarean sections rather than new drugs and equipment. © 2015 John Wiley & Sons Ltd.

Insulin and wound healing.

PubMed

Hrynyk, Michael; Neufeld, Ronald J

2014-12-01

Skin is a dynamic and complex organ that relies on the interaction of different cell types, biomacromolecules and signaling molecules. Injury triggers a cascade of events designed to quickly restore skin integrity. Depending on the size and severity of the wound, extensive physiological and metabolic changes can occur, resulting in impaired wound healing and increased morbidity resulting in higher rates of death. While wound dressings provide a temporary barrier, they are inherently incapable of significantly restoring metabolic upsets, post-burn insulin resistance, and impaired wound healing in patients with extensive burns. Exogenous insulin application has therefore been investigated as a potential therapeutic intervention for nearly a century to improve wound recovery. This review will highlight the important achievements that demonstrate insulin's ability to stimulate cellular migration and burn wound recovery, as well as providing a perspective on future therapeutic applications and research directions.

Is there an association between Caesarean section and subsequent fertility? There is no or only a slight effect of Caesarean section on future fertility. Previous studies have reported that delivery by a Caesarean section is associated with fewer subsequent pregnancies and longer inter-pregnancy intervals. The interpretation of these findings is difficult because of significant weaknesses in study designs and analytical methods, notably the potential effect of the indication for Caesarean section on subsequent delivery. Retrospective cohort study of 1 047 644 first births to low-risk women using routinely collected, national administrative data of deliveries in English maternity units between 1 April 2000 and 31 March 2012. Primiparous women aged 15-40 years who had a singleton, term, live birth in the English National Health Service were included. Women with high-risk pregnancies involving placenta praevia, pre-eclampsia, eclampsia (gestational or pre-existing), hypertension or diabetes were excluded from the main analysis. Kaplan-Meier analyses and Cox proportional hazard models were used to assess the effect of mode of delivery on time to subsequent birth, adjusted for age, ethnicity, socio-economic deprivation and year of index delivery. Among low-risk primiparous women, 224 024 (21.4%) were delivered by Caesarean section. The Kaplan-Meier estimate of the subsequent birth rate at 10 years for the cohort was 74.7%. Compared with vaginal delivery, subsequent birth rates were marginally lower after elective Caesarean for breech (adjusted hazard ratio, HR 0.96, 95% CI 0.94-0.98). Larger effects were observed after elective Caesarean for other indications (adjusted HR 0.81, 95% CI 0.78-0.83), and emergency Caesarean (adjusted HR 0.91, 95% CI 0.90-0.93). The effect was smallest for elective Caesarean for breech, and this was not statistically significant in women younger than 30 years of age (adjusted HR 0.98, 95% CI 0.96-1.01). We used birth cohorts from maternity

To estimate the incidence of scar endometriosis after different surgical procedures. A retrospective study of 72 patients diagnosed with scar endometriosis between 1978 and 2003 was performed. Patient age, site of endometriosis, previous operations, time-gap between last surgery and onset of symptoms, nodule characteristics, and recurrence were evaluated. Age ranged from 16 to 48 years. Location varied according to the previous surgery: 46 caesarean section, one hysterectomy, one in abdominal surgery, 19 episiotomy, one was a relapse and two pelvic floor procedures, two women with no previous surgery. The incidence of scar endometriosis after caesarean section was significantly higher than after episiotomy (0.2 and 0.06%, respectively: p<0.00001) with a relative risk of 3.3. Pain was the most frequent symptom. The mean time between surgery and onset of symptoms was 3.7 years. Our findings confirm that scar endometriosis is a rare condition and indicate, probably for the first time, that caesarean section greatly increases the risk of developing scar endometriosis.

The number of Caesarean births has increased worldwide. Respiratory distress syndrome is associated with caesarean delivery, especially in the absence of labor. During the latter stages of pregnancy physiologic changes occur that are accelerated with the onset of labor, which is accompanied by changes in hormones and mediators in the mother and fetus. An acceleration in the evacuation of lung liquid is held in this period, largely dependent sodium channels sensitive to amiloride than are found in the alveolar epithelium. The failure of these mechanisms can lead to newborn severe respiratory difficulty and require intensive care, mechanical ventilation and surfactant. We need to develop preventive and therapeutic strategies to improve outcomes in this vulnerable population.

Is the caesarean section rate a performance indicator of an obstetric unit?

PubMed

Singh, Ruchi; Nath Trivedi, Amarendra

2011-02-01

The indications of caesarean section are increasing. The need to respect maternal desire in the decision making has been supported by law and ethics. Some of the other contributors to the increasing caesarean section rate are breech with failed external cephalic version, decreasing rate of trial of scar, increasing induction rate and electronic fetal heart rate monitoring and changing demography. Despite the adverse effects of caesarean section, the incidence of severe morbidity and mortality is low. The strategies put forward to reduce the caesarean section rate (CSR) have not been effective and in no country or province, the CSR has come down. CSR should not be looked at in isolation or as high or low. It is the product of changing obstetric practice and societal norms and demographics. CSR not reflect the performance of a maternity unit.

To quantify maternal obesity as a risk factor for Caesarean delivery in sub-Saharan Africa. Multivariable logistic regression analysis using 31 nationally representative cross-sectional data sets from the Demographic and Health Surveys (DHS). Maternal obesity was a risk factor for Caesarean delivery in sub-Saharan Africa; a clear dose-response relationship (where the magnitude of the association increased with increasing BMI) was observable. Compared to women of optimal weight, overweight women (BMI 25-29 kg/m(2) ) were significantly more likely to deliver by Caesarean (OR: 1.54; 95% CI: 1.33, 1.78), as were obese women (30-34.9 kg/m(2) (OR: 2.39; 95%CI: 1.96-2.90); 35-39.9 kg/m(2) (OR: 2.47 95%CI: 1.78-3.43)) and morbidly obese women (BMI ≥40 kg/m(2) OR: 3.85; 95% CI: 2.46-6.00). BMI is projected to rise substantially in sub-Saharan Africa over the next few decades and demand for Caesarean sections already exceeds available capacity. Overweight women should be advised to lose weight prior to pregnancy. Furthermore, culturally appropriate prevention strategies to discourage further population-level rises in BMI need to be designed and implemented. © 2016 The Authors.

The aim of this study was to compare early wound healing, tooth staining and patient acceptance with two different post-surgical maintenance protocols. Forty patients scheduled for flap surgery to treat periodontal pockets or accommodate dental implants were randomly assigned to receive the following two different post-surgical maintenance protocols: (a) 2 weeks rinsing with a 0.05 % chlorhexidine digluconate (CHX)/herbal extract combination (test) or (b) a 0.1 % CHX solution (control). Early wound healing was evaluated clinically and immunologically. Tooth staining and patient acceptance were assessed by means of visual analogue scale (VAS). Both groups presented with comparable wound healing profiles. No statistically significant differences were observed between the two protocols regarding early wound healing and plaque index (p > 0.05). However, in the control group, statistically significantly more patients felt discomfort due to tooth staining (p = 0.0467). Compared with patients from the test group, patients in the control group reported statistically significant more irritation of taste at week 1 (p = 0.0359) and at week 2 (p = 0.0042). The present findings indicate that the two CHX protocols resulted in comparable healing and inhibition of plaque formation. Tooth staining and subjective discomfort related to irritation of taste were more frequent in the control group. A post-operative protocol including 0.05 % CHX/herbal extract may have the potential to improve patient compliance during post-operative maintenance.

Post-traumatic stress disorder managed successfully with hypnosis and the rewind technique: two cases in obstetric patients.

PubMed

Slater, P M

2015-08-01

Two obstetric patients presenting with post-traumatic stress disorder in the antenatal period are discussed. The first patient had previously had an unexpected stillborn delivered by emergency caesarean section under general anaesthesia. She developed post-traumatic stress disorder and presented for repeat caesarean section in her subsequent pregnancy, suffering flashbacks and severe anxiety. Following antenatal preparation with hypnosis and a psychological method called the rewind technique, she had a repeat caesarean section under spinal anaesthesia, successfully managing her anxiety. The second patient suffered post-traumatic stress disorder symptoms after developing puerperal psychosis during the birth of her first child. Before the birth of her second child, she was taught self-hypnosis, which she used during labour in which she had an uneventful water birth. These cases illustrate the potential value of hypnosis and alternative psychological approaches in managing women with severe antenatal anxiety. Copyright © 2015 Elsevier Ltd. All rights reserved.

Scalp Wound Closure with K wires: An alternative easier method to scalp wound closure.

PubMed

Ramesh, S; Ajik, S

2012-12-01

Scalp defects and lacerations present a reconstructive challenge to plastic surgeons. Many methods have been described from the use of skin grafting to rotation flaps. Here we present a method of closure of a contaminated scalp wound with the use of Kirschner wires. In our case, closure of scalp laceration was made possible with the use of 1.4 Kirschner wires and cable tie/ zip tie fasteners. The duration to closure of wound was 10 days. In reconstructing the scalp defect, this method was found to adhere to principles of scalp reconstruction. There were no post operative complications found from the procedure. On initial application on the edge of the wound, tension applied caused the K wires to cut through the wound edge. On replacement of K wires 1cm away from wound edge the procedure was not plagued by any further complication. In conclusion we find scalp closure with Kirschner wires are a simple and effective method for scalp wound closure.

This study, based on the Lebanese National Perinatal Survey which included 5231 women, examined the relations between the caesarean section (CS) rate and the characteristics of mothers, children, antenatal care and maternity units in two geographical zones of Lebanon (Beirut-Mount Lebanon and the rest of the country) and then looked at geographical variations. This analysis concerned 3846 women with singleton pregnancies and livebirths at low risk of CS, after exclusion of women with a previous CS, non-cephalic fetal presentations, or delivery before 37 weeks' gestation. The principal end point was caesarean delivery. The relations between the factors studied and CS were estimated by odds ratios (OR), both crude and adjusted, using logistic regression. The rate of CS was higher in the Beirut-Mount Lebanon zone than elsewhere (13.4% vs. 7.6%). After adjustment, several factors remained associated with caesarean delivery in each zone. Common factors were primiparity, gestational age > or = 41 weeks and antenatal hospitalisation. Factors identified only in the Beirut-Mount Lebanon zone were obstetric history and insurance coverage, whereas for the other zones we only found major risk factors for obstetric disease: maternal age > or = 35 years, number of antenatal consultations > or = 4 and birthweight < or = 2500 g. The multivariable analysis of the overall population, adjusting for zone of delivery and other variables, shows that zone was one of the principal factors associated with the risk of caesarean delivery in Lebanon (OR = 1.80 [95% CI 1.09, 2.95]). In conclusion, the CS rates in Lebanon were high, with geographical differences that were associated with access to care and with obstetric practices.

Caesarean delivery and subsequent pregnancy interval: a systematic review and meta-analysis

Background Caesarean delivery has increased worldwide, however, the effects on fertility are largely unknown. This systematic review aims to compare subsequent sub-fertility (time to next pregnancy or birth) among women with a Caesarean delivery to women with a vaginal delivery. Methods Systematic review of the literature including seven databases: CINAHL; the Cochrane Library; Embase; Medline; PubMed; SCOPUS and Web of Knowledge (1945 - October 2012), using detailed search-strategies and reference list cross-checking. Cohort, case–control and cross-sectional studies were included. Two assessors reviewed titles, abstracts, and full articles using standardised data abstraction forms and assessed study quality. Results 11 articles were eligible for inclusion in the systematic review, of these five articles which adjusted for confounders were combined in a meta-analysis, totalling 750,407 women using fixed-effect models. Previous Caesarean delivery was associated with an increased risk of sub-fertility [pooled odds ratio (OR) 0.90; 95% CI 0.86, 0.93]. Subgroup analyses by parity [primiparous women: OR 0.91; 95% CI 0.87, 0.96; not limited to primiparous women: OR 0.81; 95% CI 0.73, 0.90]; by publication date (pre-2000: OR 0.80, 95% CI 0.68, 0.94; post-2000: OR 0.90, 95% CI 0.86, 0.94); by length of follow-up (<10 years: OR 0.81, 95% CI 0.73, 0.90; >10 years: OR 0.91, 95% CI 0.87, 0.96); by indication for mode of delivery (specified: 0.92, 95% CI 0.88, 0.97; not specified: OR 0.81, 95% CI 0.73, 0.90); by cohort size (<35,000: OR 0.79, 95% CI 0.67, 0.92; >35,000: OR 0.90, 95% CI 0.87, 0.95), by definition of sub-fertility used divided into (birth interval [BI]: OR 0.89, 95% CI 0.84, 0.94; inter-pregnancy interval [IPI]: OR 0.91, 95% CI 0.85, 0.97; and categorical measures: OR 0.81, 95% CI 0.73, 0.90); continuous measures: OR 0.91, 95% CI 0.87, 0.96) were performed.

Why 'down under' is a cut above: a comparison of rates of and reasons for caesarean section in England and Australia

PubMed Central

2014-01-01

Background Most studies examining determinants of rising rates of caesarean section have examined patterns in documented reasons for caesarean over time in a single location. Further insights could be gleaned from cross-cultural research that examines practice patterns in locations with disparate rates of caesarean section at a single time point. Methods We compared both rates of and main reason for pre-labour and intrapartum caesarean between England and Queensland, Australia, using data from retrospective cross-sectional surveys of women who had recently given birth in England (n = 5,250) and Queensland (n = 3,467). Results Women in Queensland were more likely to have had a caesarean birth (36.2%) than women in England (25.1% of births; OR = 1.44, 95% CI = 1.28-1.61), after adjustment for obstetric characteristics. Between-country differences were found for rates of pre-labour caesarean (21.2% vs. 12.2%) but not for intrapartum caesarean or assisted vaginal birth. Compared to women in England, women in Queensland with a history of caesarean were more likely to have had a pre-labour caesarean and more likely to have had an intrapartum caesarean, due only to a previous caesarean. Among women with no previous caesarean, Queensland women were more likely than women in England to have had a caesarean due to suspected disproportion and failure to progress in labour. Conclusions The higher rates of caesarean birth in Queensland are largely attributable to higher rates of caesarean for women with a previous caesarean, and for the main reason of having had a previous caesarean. Variation between countries may be accounted for by the absence of a single, comprehensive clinical guideline for caesarean section in Queensland. PMID:24767675

Factors influencing rising caesarean section rates in China between 1988 and 2008.

To identify factors driving the rapid increase in caesarean section in China between 1988 and 2008. Data from four national cross-sectional surveys (1993, 1998, 2003 and 2008) and modified Poisson regression were used to determine whether changes in household income, access to health insurance or women's education accounted for the rise in caesarean sections in urban and rural areas. In 2008, 64.1% of urban women and 11.3% of women in the poorest rural region reported giving birth by caesarean section. A fast rise was occurring in all socioeconomic groups. Between 1993 and 2008, the risk of caesarean section had increased more than threefold in urban areas (relative risk, RR: 3.63; 95% confidence interval, CI: 2.61-5.04) and more than 15-fold in rural areas (RR: 15.46; 95% CI: 10.46-22.86). After adjustment for improvements in income, education and access to health insurance over the study period, the RR dropped minimally in urban areas (RR: 3.07; 95% CI: 2.32-4.07), which suggests that these factors do not explain the rise; in rural areas, the adjusted RR dropped to 7.18 (95% CI: 4.82-10.69), which shows that socioeconomic change is only partly responsible for the rise. Socioeconomic region of residence was a more important driver of the caesarean section rate than individual socioeconomic status. The large variation in caesarean section rate by socioeconomic region--independent of individual income, health insurance or education--suggests that structural factors related to service supply have influenced the increasing rate more than a woman's ability to pay.

To examine maternal and obstetric factors influencing births by cesarean section according to health care funding. A cross-sectional study with data from Southeastern Brazil. Caesarean section births from February 2011 to July 2012 were included. Data were obtained from interviews with women whose care was publicly or privately funded, and from their obstetric and neonatal records. Univariate and multivariate analyses were conducted to generate crude and adjusted odds ratios (OR) with 95% confidence intervals (95%CI) for caesarean section births. The overall caesarean section rate was 53% among 9,828 women for whom data were available, with the highest rates among women whose maternity care was privately funded. Reasons for performing a c-section were infrequently documented in women's maternity records. The variables that increased the likelihood of c-section regardless of health care funding were the following: paid employment, previous c-section, primiparity, antenatal and labor complications. Older maternal age, university education, and higher socioeconomic status were only associated with c-section in the public system. Higher maternal socioeconomic status was associated with greater likelihood of a caesarean section birth in publicly funded settings, but not in the private sector, where funding source alone determined the mode of birth rather than maternal or obstetric characteristics. Maternal socioeconomic status and private healthcare funding continue to drive high rates of caesarean section births in Brazil, with women who have a higher socioeconomic status more likely to have a caesarean section birth in all birth settings.

The goal of our study was to assess the perfusion in wounds treated by vacuum assisted closure (VAC) compared to primary wound closure. Power Doppler Ultrasound (PDUS) was carried out under standardised conditions in 15 VAC-treated and 10 primarily closed wounds as well as on altogether 25 intraindividual reference areas. All data were sent to a work station for post-processing to determine the perfused area. Statistical data analysis was performed with the Mann-Whitney test. Both VAC-treated wounds and primarily closed wounds showed a significant increase of the perfusion when compared to the intraindividual reference area (p < 0.0001). In VAC-treated wounds, a markedly increased perfusion was measured compared to the wounds closed primarily (p < 0.0001). Perfusion decreased during treatment, but in two VAC-treated wounds, an initial increase of the perfusion was observed. Both these wounds were grossly infected. PDUS allows the quantification of the differences in wound perfusion. This can be helpful in the detection of progressive local wound infections.

Appendectomy for asymptomatic appendicitis during caesarean section - an interesting case report.

The authors present an interesting case report of an appendectomy during caesarean section in an asymptomatic pregnant woman, which highlights the need of peritoneal cavity check during every caesarean section. A 32-year-old para 0 woman at 34 weeks of gestation attended to the present clinic because of a feeling of reduced fetal movements in the last 24 hours. She underwent a non-stress test (NST), that was non-reassuring and no contractions were recorded. The woman underwent a caesarean section, which revealed a large phlegmonic appendix. Appendectomy was decided after the closure of the uterine cavity. The woman was treated with appendectomy. Histology came back as an appendicitis three days later. Acute appendicitis during pregnancy may be associated with serious maternal and fetal complications. It is also associated with a high risk of premature delivery. In the absence of lower abdominal pain and inflammatory changes, the incidence of acute appendicitis is low, but exists. In every caesarean section at any week of gestation, we should check the peritoneal cavity and especially the appendix, as appendicitis is the most pregnant woman who mentions preterm contractions or/and reduced fetal movements.

Caesarean delivery before 39 weeks of gestation increases the risk of morbidity among infants. Taiwan has one of the highest caesarean rates in the world, but little attention has been paid to this issue. This study aimed to describe the rate of caesarean delivery before 39 weeks gestation among women who did not have labour signs and had a non-emergency caesarean delivery in Taiwan and to examine whether the phenomenon was associated with the Chinese cultural practice of selecting an auspicious time for birth. We recruited women at 15-28 weeks of pregnancy at 5 hospitals in northern Taiwan and followed them at 4 or 5 weeks after delivery using structured questionnaires. This analysis included 150 primiparous mothers with a singleton pregnancy who had a non-emergency caesarean delivery without the presence of labour signs. Ninety-three of these women (62.0%) had caesarean deliveries before 39 weeks of gestation. Logistic regression analysis showed that women who had selected an auspicious time for delivery (OR=2.82, 95% CI: 1.15-6.95) and delivered in medical centres (OR=5.26, 95% CI: 2.25-12.26) were more likely to deliver before 39 weeks of gestation. Non-emergency caesarean delivery before 39 weeks of gestation was common among the study women, and was related to the Chinese cultural practice of selecting an auspicious time for birth. Further studies are needed to examine the risks and benefits associated with timing of caesarean delivery in Taiwan in order to generate a consensus among obstetricians and give pregnant women appropriate information.

Evidence on the benefits of music during caesarean section under regional anaesthesia to improve clinical and psychological outcomes for mothers and infants has not been established. To evaluate the effectiveness of music during caesarean section under regional anaesthesia for improving clinical and psychological outcomes for mothers and infants. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2008). We included randomised controlled trials comparing music added to standard care during caesarean section under regional anaesthesia to standard care alone. Two review authors, Malinee Laopaiboon and Ruth Martis, independently assessed eligibility, risk of bias in included trials and extracted data. We analysed continuous outcomes using a mean difference (MD) with a 95% confidence interval (CI). One trial involving 76 women who planned to have their babies delivered by caesarean section met the inclusion criteria, but data were available for only 64 women. This trial was of low quality with unclear allocation concealment and only a few main clinical outcomes reported for the women. The trial did not report any infant outcomes. It appears that music added to standard care during caesarean section under regional anaesthesia had some impact on pulse rate at the end of maternal contact with the neonate in the intra-operative period (MD -7.50 fewer beats per minute, 95% CI -14.08 to -0.92) and after completion of skin suture for the caesarean section (MD -7.37 fewer beats per minute, 95% CI -13.37 to -1.37). There was also an improvement in the birth satisfaction score (maximum possible score of 35) (MD of 3.38, 95%CI 1.59 to 5.17). Effects on other outcomes were either not significant or not reported in the one included trial. The findings indicate that music during planned caesarean section under regional anaesthesia may improve pulse rate and birth satisfaction score. However, the magnitude of these benefits is small and the

We followed the progression of healing of deep excisional biopsy punch wounds over the course of 365 days in rainbow trout (Oncorhynchus mykiss) by monitoring visual wound healing and gene expression in the healing muscle at regular intervals (1, 3, 7, 14, 38 and 100 days post-wounding). In addition, we performed muscle texture analysis one year after wound infliction. The selected genes have all previously been investigated in relation to vertebrate wound healing, but only few specifically in fish. The selected genes were interleukin (IL)-1β, IL-6, transforming growth factor (TGF)-β1 and -β3, matrix metalloproteinase (MMP) -9 and -13, inducible nitric oxide synthase (iNOS), fibronectin (FN), tenascin-C (TN-C), prolyl 4-hydroxylase α1-chain (P4Hα1), lysyl oxidase (LOX), collagen type I α1-chain (ColIα1), CD41 and CD163. Wound healing progressed slowly in the presented study, which is at least partially due to the low temperature of about 8.5 °C during the first 100 days. The inflammation phase lasted more than 14 days, and the genes relating to production and remodeling of new extracellular matrix (ECM) exhibited a delayed but prolonged upregulation starting 1-2 weeks post-wounding and lasting until at least 100 days post-wounding. The gene expression patterns and histology reveal limited capacity for muscle regeneration in rainbow trout, and muscle texture analyses one year after wound infliction confirm that wounds heal with fibrosis. At 100 dpw epidermis had fully regenerated, and dermis partially regenerated. Scales had not regenerated even after one year. CD163 is a marker of "wound healing"-type M2c macrophages in mammals. M2 macrophage markers are as yet poorly described in fish. The pattern of CD163 expression in the present study is consistent with the expected timing of presence of M2c macrophages in the wound. CD163 may thus potentially prove a valuable marker of M2 macrophages - or a subset hereof - in fish. We subjected a group of fish to

To characterize predischarge maternal pain and stress after caesarean delivery and short hospitalization. This is a descriptive study with 60 women in the postoperative period of caesarean section and 60 control women after vaginal delivery. Pain and stress were measured by McGill Pain Questionnaire (MGPQ) and by the Stress Measure (Psychological Stress Measure (PSM)), respectively, at mother-infant dyad discharge, scheduled at 36 hours after delivery. Caesarean section was the delivery modality with the highest MGPQ pain and sensorial, evaluative and mixed pain descriptive categories scores. The pain location involved lower abdomen, with associated localizations at back, breast and shoulders. Conversely, vaginal delivery was the delivery modality with the highest stress scores. This study provides important information on the quality of care implications of early discharge practices in puerperae after caesarean delivery, a critical time characterized by qualitatively and quantitatively high pain and stress.

Identifying factors associated to Caesarean sections among the residents of Maringá-PR, according to the financing source for delivery. A cross-sectional study with data from 920 postpartum women interviewed between October 2013 and February 2014. Association analysis was performed by logistic regression. Caesarean section rates were 55.5% in the Unified Healthcare System (SUS) and 93.8% in the private system. Factors associated with Caesarean section in the SUS were: previous Caesarean section (OR=8.9; CI=4.6-16.9), desire for Caesarean section early in pregnancy (OR=2.0; CI=1.1-3.6), pregestational overweight/obesity (OR=1.8; CI=1.1-2.8), and per capita family income higher than one minimum wage (OR=2.1; CI=1.3-3.4). In the private system, desire for Caesarean section early in pregnancy (OR=25.3) and a previous Caesarean section (OR=11.3) were strongly associated to its performance. It is necessary to properly orientate all pregnant women who desire a Caesarean delivery, from both the SUS and the private system, about the inherent risks of the surgical procedure without indication. In the public health sector, guidelines should be focused on pregnant women with previous Caesarean delivery, with a per capita income higher than one minimum wage and those who are overweight or obese, as these women are more likely to have a Caesarean section.

Thirty years of the World Health Organization's target caesarean section rate: time to move on.

PubMed

Robson, Stephen J; de Costa, Caroline M

2017-03-06

It has been 30 years since the World Health Organization first recommended a "maximum" caesarean section (CS) rate of 15%. There are demographic differences across the 194 WHO member countries; recent analyses suggest the optimal global CS rate is almost 20%. Attempts to reduce CS rates in developed countries have not worked. The strongest predictor of caesarean delivery for the first birth of "low risk" women appears to be maternal age; a factor that continues to increase. Most women whose first baby is born by caesarean delivery will have all subsequent children by caesarean delivery. Outcomes that informed the WHO recommendation primarily relate to maternal and perinatal mortality, which are easy to measure. Longer term outcomes, such as pelvic organ prolapse and urinary incontinence, are closely related to mode of birth, and up to 20% of women will undergo surgery for these conditions. Pelvic floor surgery is typically undertaken for older women who are less fit for surgery. Serious complications such as placenta accreta occur with repeat caesarean deliveries, but the odds only reach statistical significance at the third or subsequent caesarean delivery. However, in Australia, parity is falling, and only 20% of women will have more than two births. We should aim to provide CS to women in need and to continue including women in the conversation about the benefits and disadvantages, both short and long term, of birth by caesarean delivery.

Aloe vera and Vitis vinifera have been traditionally used as wound healing agents. The present study aimed to investigate the effects of aloe emodin and resveratrol in the burn wound healing procedure. Burn wounds are common in developed and developing countries, however, in developing countries, the incidence of severe complications is higher and financial resources are limited. The results of the present study demonstrated that neither aloe emodin or resveratrol were cytotoxic to THP-1 macrophages at concentrations of 1, 100 and 500 ng/ml. A significant increase in wound-healing activity was observed in mice treated with the aloe emodin and resveratrol, compared with those which received control treatments. The levels of IL-1β in the exudates of the burn wound area of the treated mice increased in a time-dependent manner over 7 days following burn wound injury. At 10 days post-injury, steady and progressive wound healing was observed in the control animals. The present study confirmed that increased wound healing occurs following treatment with aloe emodin,, compared with resveratrol, providing support for the use of Aloe vera plants to improve burn wound healing.

External cephalic version (ECV) in the presence of a uterine scar is still considered a relative contraindication despite encouraging studies of the efficacy and safety of this procedure. We present our experience with this patient population, which is the largest cohort published to date. To evaluate the efficacy and safety of ECV in the setting of a prior caesarean delivery. A total of 158 patients with a fetus presenting as breech, who had an unscarred uterus, had an ECV performed. Similarly, 158 patients with a fetus presenting as breech, and who had undergone a prior caesarean delivery also underwent an ECV. Outcomes were compared. ECV was successfully performed in 136/158 (86.1%) patients in the control group. Of these patients, 6/136 (4.4%) delivered by caesarean delivery. In the study group, 117/158 (74.1%) patients had a successful ECV performed. Of these patients, 12/117 (10.3%) delivered by caesarean delivery. There were no significant complications in either of the groups. ECV may be successfully performed in patients with a previous caesarean delivery. It is associated with a high success rate, and is not associated with an increase in complications. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Post-surgical wound management of pilonidal cysts with a haemoglobin spray: a case series.

PubMed

Mustafi, N; Engels, P

2016-04-01

Painful acute cysts in the natal cleft or lower back, known as pilonidal sinus disease, are a severe burden to many younger patients. Although surgical intervention is the preferred first line treatment, postsurgical wound healing disturbances are frequently reported due to infection or other complications. Different treatment options of pilonidal cysts have been discussed in the literature, however, no standardised guideline for the postsurgical wound treatment is available. After surgery, a common recommended treatment to patients is rinsing the wound with clean water and dressing with a sterile compress. We present a case series of seven patients with wounds healing by secondary intention after surgical intervention of a pilonidal cyst. The average age of the patients was 40 years old. Of the seven patients, three had developed a wound healing disturbance, one wound had started to develop a fibrin coating and three were in a good condition. The applied wound care regimens comprised appropriate mechanical or autolytic debridement, rinsing with an antimicrobial solution, haemoglobin application, and primary and secondary dressings. In all seven cases a complete wound closure was achieved within an average of 76 days with six out of seven wounds achieving wound closure within 23-98 days. Aesthetic appearance was deemed excellent in five out of seven cases excellent and acceptable in one. Treatment of one case with a sustained healing disturbance did result in wound closure but with a poor aesthetic outcome and an extensive cicatrisation of the new tissue. Based on these results we recommend that to avoid healing disturbances of wounds healing by secondary intention after surgical pilonidal cyst intervention, an adequate wound care regime comprising appropriate wound debridement, rinsing, topically applied haemoglobin and adequate wound dressing is recommendable as early as possible after surgery.

Hypertrophic scar was first described over 100 years ago; PubMed has more than 1,000 references on the topic. Nevertheless prevention and treatment remains poor, because 1) there has been no validated animal model; 2) human scar tissue, which is impossible to obtain in a controlled manner, has been the only source for study; 3) tissues typically have been homogenized, mixing cell populations; and 4) gene-by-gene studies are incomplete. We have assembled a system that overcomes these barriers and permits the study of genome-wide gene expression in microanatomical locations, in shallow and deep partial-thickness wounds, and pigmented and non-pigmented skin, using the Duroc(pigmented fibroproliferative)/Yorkshire(non-pigmented non-fibroproliferative) porcine model. We used this system to obtain the differential transcriptome at 1, 2, 3, 12 and 20 weeks post wounding. It is not clear when fibroproliferation begins, but it is fully developed in humans and the Duroc breed at 20 weeks. Therefore we obtained the derivative functional genomics unique to 20 weeks post wounding. We also obtained long-term, forty-six week follow-up with the model. 1) The scars are still thick at forty-six weeks post wounding further validating the model. 2) The differential transcriptome provides new insights into the fibroproliferative process as several genes thought fundamental to fibroproliferation are absent and others differentially expressed are newly implicated. 3) The findings in the derivative functional genomics support old concepts, which further validates the model, and suggests new avenues for reductionist exploration. In the future, these findings will be searched for directed networks likely involved in cutaneous fibroproliferation. These clues may lead to a better understanding of the systems biology of cutaneous fibroproliferation, and ultimately prevention and treatment of hypertrophic scarring.

Previous caesarean delivery and intended mode of delivery after caesarean are well-known individual risk factors for uterine rupture. We examined if different national rates of uterine rupture are associated with differences in national rates of previous caesarean delivery and intended mode of delivery after a previous caesarean delivery. This study is an ecological study based on data from a retrospective cohort in the Nordic countries. Data on uterine rupture were collected prospectively in each country as part of the Nordic obstetric surveillance study and included 91% of all Nordic deliveries. Information on the comparison population was retrieved from the national medical birth registers. Incidence rate ratios by previous caesarean delivery and intended mode of delivery after caesarean were modelled using Poisson regression. The incidence of uterine rupture was 7.8/10 000 in Finland and 4.6/10 000 in Denmark. Rates of caesarean (21.3%) and previous caesarean deliveries (11.5%) were highest in Denmark, while the rate of intended vaginal delivery after caesarean was highest in Finland (72%). National rates of uterine rupture were not associated with the population rates of previous caesarean but increased by 35% per 1% increase in the population rate of intended vaginal delivery and in the subpopulation of women with previous caesarean delivery by 4% per 1% increase in the rate of intended vaginal delivery. National rates of uterine rupture were not associated with national rates of previous caesarean, but increased with rates of intended vaginal delivery after caesarean. © 2017 John Wiley & Sons Ltd.

2013-01-01

Background There is evidence that induction of labour (IOL) around term reduces perinatal mortality and caesarean delivery rates when compared to expectant management of pregnancy (allowing the pregnancy to continue to await spontaneous labour or definitive indication for delivery). However, it is not clear whether IOL in women with a previous caesarean section confers the same benefits. The aim of this study was to describe outcomes of IOL at 39–41 weeks in women with one previous caesarean delivery and to compare outcomes of IOL or planned caesarean delivery to those of expectant management. Methods and Findings We performed a population-based retrospective cohort study of singleton births greater than 39 weeks gestation, in women with one previous caesarean delivery, in Scotland, UK 1981–2007 (n = 46,176). Outcomes included mode of delivery, perinatal mortality, neonatal unit admission, postpartum hemorrhage and uterine rupture. 40.1% (2,969/7,401) of women who underwent IOL 39–41 weeks were ultimately delivered by caesarean. When compared to expectant management IOL was associated with lower odds of caesarean delivery (adjusted odds ratio [AOR] after IOL at 39 weeks of 0.81 [95% CI 0.71–0.91]). There was no significant effect on the odds of perinatal mortality but greater odds of neonatal unit admission (AOR after IOL at 39 weeks of 1.29 [95% CI 1.08–1.55]). In contrast, when compared with expectant management, elective repeat caesarean delivery was associated with lower perinatal mortality (AOR after planned caesarean at 39 weeks of 0.23 [95% CI 0.07–0.75]) and, depending on gestation, the same or lower neonatal unit admission (AOR after planned caesarean at 39 weeks of 0.98 [0.90–1.07] at 40 weeks of 1.08 [0.94–1.23] and at 41 weeks of 0.77 [0.60–1.00]). Conclusions A more liberal policy of IOL in women with previous caesarean delivery may reduce repeat caesarean delivery, but increases the risks of neonatal complications. PMID:23565242

Anaesthesia for Caesarean section in a patient with Parkinson's disease.

Ward, V D

2018-05-01

Parkinson's disease is prevalent worldwide but mainly affects the elderly and is rarely seen in women of child-bearing age. The clinical signs and symptoms, the physiological changes of pregnancy, and drug interactions, pose unique challenges for the anaesthetic management of patients with Parkinson's disease who present for delivery. A 36-year-old primigravid woman at 36 weeks' gestation, with Parkinson's disease, presented for pre-anaesthesia assessment prior to elective caesarean section. Her Parkinson's disease had been diagnosed four years previously and was treated with Sinemet (levodopa/carbidopa) and pramipexole. Despite maximum allowable drug doses in pregnancy, she reported disease progression, with right-sided weakness in the upper and lower limbs and an altered gait. Spinal anaesthesia for elective Caesarean section was performed in the sitting position, using 0.5% hyperbaric bupivacaine, morphine 150 µg and fentanyl 25 µg. The anaesthesia and Caesarean section were uneventful. She was discharged home with a healthy baby on the fourth postoperative day. Copyright © 2017 Elsevier Ltd. All rights reserved.

Facial laceration at caesarean section: experience with tissue adhesive.

PubMed

Saraf, Sanjay

2009-01-01

The fetal laceration is one of the most commonly identified injuries at the caesarean delivery. The incidence in the literature has been reported to be as high as 3%. The management of such injuries has remained a perplexing problem for both the physician and the parents. We present a case of a newborn who accidentally sustained laceration over the face during a caesarean delivery. A review of the literature and management of lacerations with tissue adhesives has been presented. The laceration was successfully managed with tissue adhesive alone with good aesthetic outcome. Topical 2-octylcyanoacrylate tissue adhesives can be an effective alternative therapy for traditional devices for closing simple low-tension lacerations.

To observe the effects of combined FE enzymes on the infection of the granulation burn wound during late postburn stage in controlling burn wound infection caused by common antibiotic resistant bacteria. Thirty patients in our burn ward were enrolled and were randomly divided into A [treated with combined FE enzymes (50 ml dissolved in 0-150 ml normal saline to reach the final concentration of 1-3 U/ml)] and B (treated with gentamicin) groups, with 15 patients in each group. Several layers of gauze, either soaked with combined FE enzyme in A or gentamicin in B group, were used to cover the burn wounds once to twice a day. Bacterial culture from the burn wound exudation before and after drug administration was done before the application of the agents. The bacteria in the burn wounds and their susceptibility to antibiotics were identified. The healing time of the burn wounds was recorded. Furthermore, the healing rate of the burn wound was recorded on the 3rd, 5th, 8th, 10th and 12th post skin grafting days (PSGD). The dominating bacteria in the burn wounds in both groups were Pseudomonas aeruginosa, Escherichia coli, Enterobacter cloacae and MRSA. The susceptibility rate of bacteria ( MRSA, Staphylococcus epidermidis, Staphylococcus saprophyte, Pseudomonas aeruginosa, Escherichia coli and Enterobacter cloacae) to combined FE enzyme was 93.8%, 100.0%, 100.0%, 100.0%, 100.0% and 95.0% respectively, which were much higher than those in B group (17.6%, 31.3%, 28.6%, 44.0%, 33.3%, 28.0% respectively, P < 0.1. The wound healing time after skin grafting in A group (10.6 +/- 1.5 days) was significantly shorter than that in B group (15.3 +/- 1.7 days, P < 0.01). The wound healing rate on 10 PSGD in A group was (85.4 +/- 2.4)%, and which was only (51.3 +/- 1.5% in B group (P < 0.01) Combined FE enzyme can effectively control burn wound infection, so that the interval between skin grafting and wound healing can be shortened and success rate of skin grafting be improved.

Pediatric Surgeon-Directed Wound Classification Improves Accuracy

Background Surgical wound classification (SWC) communicates the degree of contamination in the surgical field and is used to stratify risk of surgical site infection and compare outcomes amongst centers. We hypothesized that changing from nurse-directed to surgeon-directed SWC during a structured operative debrief we will improve accuracy of documentation. Methods An IRB-approved retrospective chart review was performed. Two time periods were defined: initially, SWC was determined and recorded by the circulating nurse (Pre-Debrief 6/2012-5/2013) and allowing six months for adoption and education, we implemented a structured operative debriefing including surgeon-directed SWC (Post-Debrief 1/2014-8/2014). Accuracy of SWC was determined for four commonly performed Pediatric General Surgery operations: inguinal hernia repair (clean), gastrostomy +/− Nissen fundoplication (clean-contaminated), appendectomy without perforation (contaminated), and appendectomy with perforation (dirty). Results 183 cases Pre-Debrief and 142 cases Post-Debrief met inclusion criteria. No differences between time periods were noted in regards to patient demographics, ASA class, or case mix. Accuracy of wound classification improved Post-Debrief (42% vs. 58.5%, p=0.003). Pre-Debrief, 26.8% of cases were overestimated or underestimated by more than one wound class, vs. 3.5% of cases Post-Debrief (p<0.001). Interestingly, the majority of Post-Debrief contaminated cases were incorrectly classified as clean-contaminated. Conclusions Implementation of a structured operative debrief including surgeon-directed SWC improves the percentage of correctly classified wounds and decreases the degree of inaccuracy in incorrectly classified cases. However, following implementation of the debriefing, we still observed a 41.5% rate of incorrect documentation, most notably in contaminated cases, indicating further education and process improvement is needed.

Gum chewing has been reported to enhance the intestinal function recovery after caesarean section, current perspectives and practice guidelines vary widely on the use of gum chewing, more studies on the role of gum chewing after caesarean section are needed. We performed a comprehensive, systematic meta-analysis of randomized controlled trials (RCTs) on the efficacy of gum chewing after caesarean section. Studies were identified by searching EMBASE et al database (until June 30, 2016). Summary odd ratios or weighted mean differences with 95% confidence intervals were calculated for each outcome with fixed- or random-effects model. Ten RCTs with a total of 1659 women were included in our meta-analysis. Gum chewing provided significant benefits in reducing the time to first passage of flatus, first defecation, first bowel sound, first bowel movement and the length of hospital stay, but not in the time to first feeling of hunger. Gun chewing hastens the intestinal function recovery after caesarean section and offers a safe and inexpensive option. High-quality and larger-scale RCTs are still warranted to clarify the role of gum chewing in intestinal function recovery after caesarean section.

Antibiotics are used both pre and post-operatively in acute appendicitis for preventing wound infection. It has been observed that the routine use of post-operative antibiotics is not necessary in cases of non-perforated appendicitis as only prophylactic antibiotics are sufficient to prevent wound infection. The aim of this study was to see the frequency of wound infection in non-perforated appendicitis with single dose preoperative antibiotics only. This observational study was conducted at the Department of Surgery, Ayub Medical College, Abbottabad from May to November 2014. A total of 121 patients with non-perforated appendicitis were included in the study. Only single dose preoperative antibiotics were used. The patients were followed for wound infection till 8th post-operative day. 121 patients, 56 (46.28%) male and 65 (53.72%) female were included in the study. The mean age of patients was 27.41 +/- 7.12 years with an age range of 18 to 45 years. In the entire series, 7 (5.78%) patients developed wound infection. The infection was minor which settled with conservative therapy. Prophylactic antibiotics were found efficacious in 114 (94.21%) patients. There was no significant association between wound infection and age and gender. Single dose preoperative antibiotics were found effective in controlling post-operative wound infection without the need of extending the antibiotics to post-operative period in cases of non-perforated appendicitis.

We recently performed proteomic characterization of a modified collagen gel (MCG) dressing and reported promising effects of the gel in healing full-thickness excisional wounds. In this work, we test the translational relevance of our aforesaid findings by testing the dressing in a swine model of chronic ischemic wounds recently reported by our laboratory. Full thickness excisional wounds were established in the center of bi- pedicle ischemic skin flaps on the backs of animals. Ischemia was verified by Laser Doppler imaging and MCG was applied to the test group of wounds. Seven days post- wounding, macrophage recruitment to the wound was significantly higher in MCG- treated ischemic wounds. In vitro, MCG up-regulated expression of Mrc-1 (a reparative M2 macrophage marker) and induced the expression of anti-inflammatory cytokine IL-10 and of β-FGF. An increased expression of CCR2, a M2 macrophage marker, was noted in the macrophages from MCG treated wounds. Furthermore, analyses of wound tissues 7 days post wounding showed up-regulation of TGF-β, VEGF, vWF, and collagen type I expression in MCG-treated ischemic wounds. At 21 days post-wounding, MCG-treated ischemic wounds displayed higher abundance of proliferating endothelial cells that formed mature vascular structures and increased blood flow to the wound. Fibroblast count was markedly higher in MCG-treated ischemic wound-edge tissue. In addition, MCG-treated wound-edge tissues displayed higher abundance of mature collagen with increased collagen type I:III deposition. Taken together, MCG helped mount a more robust inflammatory response which resolved in a timely manner, followed by an enhanced proliferative phase, angiogenic outcome and post-wound tissue remodeling. Findings of the current study warrant clinical testing of MCG in a setting of ischemic chronic wounds. PMID:25224310

To describe obstetrical providers' delivery preferences and attitudes towards caesarean section without medical indication, including on maternal request, and to examine the association between provider characteristics and preferences/attitudes. Cross-sectional study. Two public and two private hospitals in Argentina. Obstetrician-gynaecologists and midwives who provide prenatal care and/or labour/delivery services. Providers in hospitals with at least 1000 births per year completed a self-administered, anonymous survey. Provider delivery preference for low-risk women, perception of women's preferred delivery method, support for a woman's right to choose her delivery method and willingness to perform caesarean section on maternal request. 168 providers participated (89.8% coverage rate). Providers (93.2%) preferred a vaginal delivery for their patients in the absence of a medical indication for caesarean section. Whereas 74.4% of providers supported their patient's right to choose a delivery method in the absence of a medical indication for caesarean section and 66.7% would perform a caesarean section upon maternal request, only 30.4% would consider a non-medically indicated caesarean section for their own personal delivery or that of their partner. In multivariate adjusted analysis, providers in the private sector [odds ratio (OR) 4.70, 95% CI 1.19-18.62] and obstetrician-gynaecologists (OR 4.37, 95% CI 1.58-12.09) were more willing than either providers working in the public/both settings or midwives to perform a caesarean section on maternal request. Despite the ethical debate surrounding non-medically indicated caesarean sections, we observe very high levels of support, especially by providers in the private sector and obstetrician-gynaecologists, as aligned with the high caesarean section rates in Argentina.

The objective of this study is to answer the question: have we not been doing a lot of caesarean sections at University Teaching Hospital of Dakar? This is an analytic study about caesarean section in 1992, 1996 and 2001; it was a prospective and longitudinal data collection from the epidemiological survey program carried through in Senegal about its obstetrical and surgical cover. For each year concerned, we have analysed caesarean section rate, maternal mortality rate and perinatal mortality rate. To eliminate the random part in observed variation, we used the comparison of proportions observed as a statistical test with a significant threshold less or equal to 5%. Caesarean section has gone from 12% in 1992 to 17.5 in 1996 and 25.2% in 2001. Operative indications are dominated by foeto-pelvic disproportion with an average of 31% and foetal suffering with an average of 25%. The increasing trend has been statistically significant for information's such as foeto-pelvic disproportion and maternal pathologies. The falling trend was statistically significant for indications in relation on relation to foetal suffering and scarred uterus. Gathering information has shown a stabilisation of "obligatory" caesarean rate around 41%, a decrease in "caution" caesarean rate from 50 to 37.2% and an increase in caesarean by "necessity" from 8.6 to 22.4%. The maternal mortality rate among women delivered has fallen from 1.4% to 0.8%, but postoperative surgery morbidity rate was still high around 10%, essentially due to infections. Reading of caesarean section rate has not a significant impact in perinatal prognosis. Today there is an inflation of caesarean section at University Teaching Hospital of Dakar, without any significant loss of the maternal and perinatal mortality rate. The high level of complications due to surgery incite to reverse trends in order to get reasonable rate around 10 to 15% of childbirths.

While there is evidence of an association between caesarean birth and increased asthma in children in high-income countries, it is unknown whether this association exists in low-to-middle-income countries (LMICs). We investigated whether children born through caesarean in India and Vietnam are at increased risk of caregiver-reported asthma by 8 years of age. Data from an ongoing multi-national longitudinal cohort study (the Young Lives Study) in two LMICs (India n = 2026; Vietnam n = 2000) were used. Caregiver questionnaires captured information on caregiver-reported long-term respiratory problems such as asthma or wheeze at age 8 years, birth mode and a range of sociodemographic factors. Multivariable logistic regression models using propensity score adjustment were used to explore birth mode and asthma at age 8 years adjusted for a range of known confounders. Children delivered by caesarean in India (odds ratio (OR) 2.6, 95% confidence interval (CI) 1.3, 5.4) and Vietnam (OR 2.0, 95% CI 1.2, 3.3) had greater odds of asthma at age 8 years, after adjustment for other risk factors including wealth, liveborn parity, low birthweight, geographic location, cooking fuel used, livestock ownership, household size, housing quality and parental smoking. The study suggests that caesarean birth may be associated with an increased risk of childhood asthma in India and Vietnam. The underlying mechanisms of this finding need to be further elucidated. © 2016 John Wiley & Sons Ltd.

After Super Typhoon Haiyan, a category 5 tropical cyclone, insufficient resources were available for medical management. Many patients in the Philippines were wounded as a result of the disaster. We examined the prevalence, risk factors, and consequences of disaster-related wounds and wound infection in the post-disaster period. We performed a retrospective review of consecutive patients admitted to a Korean Disaster Relief Team clinic at St. Paul's Hospital, Tacloban City, Republic of Philippines, between December 9 and 13, 2013. Traumatic injury patients were included; patients not exhibiting a wound were excluded. Of the 160 patients enrolled in the study, 71 (44.4%) had infected wounds. There were no significant differences in the age, sex, past medical history, wound site, wound depth, injury mechanism, or inducer of injury between the uninfected and infected groups. In the univariate analysis, a foreign-body-contaminated wound, a chronic wound, elapsed time from injury to medical contact, an inadequately cared for wound, and need for subsequent wound management were associated with wound infection (P<0.05). The multivariate analysis revealed that foreign body contamination and having an inadequately cared for wound were associated with wound infection (odds ratio [OR]: 10.12, 95% confidence interval [CI]: 3.59-28.56; OR: 3.51, 95% CI: 1.07-11.51, respectively). In the post-disaster situation, many wound infections required definitive care. Wound infection was associated with inadequately cared for wounds and foreign-body-contaminated wounds.

Management of extravasation injuries over the dorsum of hand after administration of chemotherapeutic agents. To study the results of hypogastric flap reconstruction in chemotherapy extravasation wounds over dorsum of hand. Retrospective study. At our center over 3-years period, 32 patients were treated for chemotherapy extravasation wounds. Out of these 32 patients, seven had wound over dorsum of hand. There were five males and two females, and their mean age was 45 years (range, 19 - 64 years). These patients with wound over the dorsum of hand were treated with multiple debridements and hypogastric flap reconstruction. The mean interval between extravasation wound and surgical treatment was 6.28 days (range, 4 - 10). The mean size of extravasation wound defect was 14 × 8 (range, 12 × 7 to 18 × 8). Non-dominant hand was involved in six patients and dominant hand in one patient. In four patients, the hypogastric flap was supplemented with skin graft. The hypogastric flap settled well in all patients and enabled a good wound cover. Complete division of the flap and final insetting was done under local anesthesia after 3 weeks; this was followed by limb mobilization exercises. Contour difference over the dorsum of hand was present in all the cases. The range of movement of the hand was functionally restricted in one patient. No patient in current series developed wound infection. Hypogastric flap is a reliable flap to cover wound over dorsum of hand after extravasation of chemotherapeutic agents.

To identify the determinants and measure the trends in health facility-based deliveries and caesarean sections among married adolescent girls in Bangladesh. In order to measure the trends in health facility-based deliveries and caesarean sections, Bangladesh Demographic Health Survey (BDHS) data sets were analysed (BDHS; 1993-1994, 1996-1997, 1999-2000, 2004, 2007, 2011). The BDHS 2011 data sets were analysed to identify the determinants of health facility-based deliveries and caesarean sections. A total of 2813 adolescent girls (aged 10-19 years) were included for analysis. Bivariate and multivariate analyses were performed. Health facility-based deliveries have continuously increased among adolescents in Bangladesh over the past two decades from 3% in 1993-1994 to 24.5% in 2011. Rates of population-based and facility-based caesarean sections have increased linearly among all age groups of women including adolescents. Although the country's overall (population-based) caesarean section rate among adolescents was within acceptable range (11.6%), a rate of nearly 50% health facility level caesarean sections among adolescent girls is alarming. Among adolescent girls, use of antenatal care (ANC) appeared to be the most important predictor of health facility-based delivery (OR: 4.04; 95% CI 2.73 to 5.99), whereas the wealth index appeared as the most important predictor of caesarean sections (OR: 5.7; 95% CI 2.74 to 12.1). Maternal health-related interventions should be more targeted towards adolescent girls in order to encourage them to access ANC and promote health facility-based delivery. Rising trends of caesarean sections require further investigation on indication and provider-client-related determinants of these interventions among adolescent girls in Bangladesh.

Poorly designed experiments and popular media have led to multiple myths about wound ballistics. Some of these myths have been incorporated into the trauma literature as fact and are included in Advanced Trauma Life Support (ATLS). We hypothesized that these erroneous beliefs would be prevalent, even among those providing care for patients with gunshot wounds (GSWs), but could be addressed through education. ATLS course content was reviewed. Several myths involving wound ballistics were identified. Clinically relevant myths were chosen including wounding mechanism, lead poisoning, debridement, and antibiotic use. Subsequently, surgery and emergency medicine services at three different trauma centers were studied. All three sites were busy, urban trauma centers with a significant amount of penetrating trauma. A pre-test was administered prior to a lecture on wound ballistics followed by a post-test. Pre- and post-test scores were compared and correlated with demographic data including ATLS course completion, firearm/ballistics experience, and years of post-graduate medical experience (PGME). One-hundred and fifteen clinicians participated in the study. A mean pre-test score of 34 % improved to 78 % on the post-test with associated improvements in all areas of knowledge (p < 0.001). Years of PGME correlated with higher pre-test score (p = 0.021); however, ATLS status did not (p = 0.774). Erroneous beliefs involving wound ballistics are prevalent even among clinicians who frequently treat victims of GSWs and could lead to inappropriate treatment. Focused education markedly improved knowledge. The ATLS course and manual promulgate some of these myths and should be revised.

Facial Laceration at Caesarean Section: Experience With Tissue Adhesive

PubMed Central

Saraf, Sanjay

2009-01-01

Background: The fetal laceration is one of the most commonly identified injuries at the caesarean delivery. The incidence in the literature has been reported to be as high as 3%. The management of such injuries has remained a perplexing problem for both the physician and the parents. Materials and Methods: We present a case of a newborn who accidentally sustained laceration over the face during a caesarean delivery. A review of the literature and management of lacerations with tissue adhesives has been presented. Results: The laceration was successfully managed with tissue adhesive alone with good aesthetic outcome. Conclusion: Topical 2-octylcyanoacrylate tissue adhesives can be an effective alternative therapy for traditional devices for closing simple low-tension lacerations. PMID:19198643

Vaginal birth is a safe mode of birth for most women who have had a prior caesarean with a transverse incision. Despite the evidence, most Taiwanese women who have had a previous caesarean are rarely offered the opportunity to consider any possibility other than a repeat caesarean. This study explored factors affecting Taiwanese women's decisionmaking regarding vaginal birth after cesarean. Ajzen's Theory of Planned Behaviour provided the theoretical framework to underpin the study, which adopted an interpretive descriptive methodology. Sequential semi-structured interviews were conducted with 29 women who had a previous caesarean and were pregnant between 34 and 38 weeks gestation, ten women who attempted vaginal birth in the third to fifth day postpartum, and 25 women in the fourth week postpartum. Boyatzis' method of thematic analysis was used to identify themes and codes. This paper reports the findings of the prenatal interviews with 29 participants. The major factor influencing women's decision-making was to avoid negative outcomes for themselves and their babies. Three thematic codes describe influences on the women's decisions: 'past experience of childbirth', 'anticipating the next experience of normal birth' and 'contemplation on the process of childbirth'. Women who have had a previous caesarean section are prepared to have a vaginal birth but are not always supported to carry out this decision. Changing the models of antenatal care is recommended as a strategy to overcome this difficulty therefore empowering women to make a meaningful choice about VBAC after a CS.

2017-01-01

Clinical features of surgical soft tissue wound healing in dentistry have been rarely discussed in the international literature. The aim of the present paper is to highlight both the main clinical findings of surgical wound healing, especially in periodontal and implant dentistry, and the wound healing monitoring procedures which should be followed. Wound inspection after careful food and plaque debridement is the essential part of wound healing monitoring. Periodontal and peri-implant probing should be performed only after tissue healing has been completed and not on a weekly basis in peri-implant tissue monitoring. Telephone follow-up and patient self-assessment scales can also be used the days following surgery to monitor the most common surgical complications such as pain, swelling, bleeding, and bruising. Wound healing monitoring is an important concern in all surgical procedures since it allows to identify signs or/and symptoms possibly related to surgical complications. PMID:28824306

Comparative, randomized, double-blind, interventional study. Liaquat University Hospital Hyderabad from October 2005 to December 2006. 480 ASA I-II full term pregnant women, 18 to 45 years of age, scheduled for elective Caesarean section, under spinal anaesthesia, were randomized into three groups: Group I (25G Quincke spinal needle: n=168), Group II (27G Quincke spinal needle: n=160) and Group III (27G Whitacre spinal needle: n=152). Spinal anaesthesia was performed with 1.5-2.0 ml 0.75% hyperbaric bupivacaine using 25G Quincke spinal needle (Group I), 27G Quincke spinal needle (Group II) and 27G Whitacre spinal needle (Group III) at L3-4 inter-vertebral space. Each patient was assessed daily for four consecutive days following Caesarean section. Frequency and severity and of postdural puncture headache (PDPH) were recorded. Data were analyzed using SPSS-11. Frequency of PDPH following the use of 25G Quincke (Group I), 27G Quincke (Group II) and 27G Whitacre (Group III) spinal needles was 8.3% (14/168), 3.8% (6/160) and 2.0% (3/152) respectively. In Group I, PDPH was mild in 5 patients, moderate in 7 patients and severe in 2 patients. In Group II, it was mild in 2, moderate in 3 and severe in 1 patient. In group III, it was mild in 2 and moderate in 1 patient. Severe PDPH did not occur in Group III. Most of the patients with PDPH developed it on 1st and 2nd postoperative day. When using a 27G Whitacre spinal needle, the frequency and severity of PDPH was significantly lower than when a 25G Quincke or 27G Quincke needle was used.

This study evaluated the effects of vaginal and caesarean delivery on internal and external anal sphincter muscle thickness using translabial ultrasonography (TL-US). This prospective cohort study enrolled nulliparous women who either had vaginal or caesarean deliveries. The thickness of the hypoechoic internal anal sphincter (IAS) and hyperechoic external anal sphincter (EAS) at the 12, 3, 6, and 9 o'clock positions at the distal level were measured before delivery and within 24-48 h after delivery. A total 105 consecutive women were enrolled in the study: 60 in the vaginal delivery group and 45 in the caesarean delivery group. The IAS muscle thickness at the 12 o'clock position in the vaginal delivery group was significantly thicker before compared with after delivery (mean ± SD: 2.31 ± 0.74 mm versus 1.81 ± 0.64 mm, respectively). The EAS muscle thickness at the 12 o'clock position in the vaginal delivery group was significantly thicker before compared with after delivery (mean ± SD: 2.42 ± 0.64 mm versus 1.97 ± 0.85, respectively). There was significant muscle thinning of both the IAS and EAS at the 12 o'clock position after vaginal delivery, but not after caesarean delivery. © The Author(s) 2016.

The frequency of caesarean section delivery varies between countries and social groups. Among other factors, it is determined by the quality of obstetrics care. Rates of elective (planned) and emergency (in-labor) caesareans may also vary between immigrants (first generation), their offspring (second- and third-generation women), and non-immigrants because of access and language barriers. Other important points to be considered are whether caesarean section indications and the neonatal outcomes differ in babies delivered by caesarean between immigrants, their offspring, and non-immigrants. A standardized interview on admission to delivery wards at three Berlin obstetric hospitals was performed in a 12-month period in 2011/2012. Questions on socio-demographic and care aspects and on migration (immigrated herself vs. second- and third-generation women vs. non-immigrant) and acculturation status were included. Data was linked with information from the expectant mothers' antenatal records and with perinatal data routinely documented in the hospital. Regression modeling was used to adjust for age, parity and socio-economic status. The caesarean section rates for immigrants, second- and third-generation women, and non-immigrant women were similar. Neither indications for caesarean section delivery nor neonatal outcomes showed statistically significant differences. The only difference found was a somewhat higher rate of crash caesarean sections per 100 births among first generation immigrants compared to non-immigrants. Unlike earlier German studies and current studies from other European countries, this study did not find an increased rate of caesarean sections among immigrants, as well as second- and third-generation women, with the possible exception of a small high-risk group. This indicates an equally high quality of perinatal care for women with and without a migration history.

Abstract Objective To provide an update on economic related inequalities in caesarean section rates within countries. Design Secondary analysis of demographic and health surveys and multiple indicator cluster surveys. Setting 72 low and middle income countries with a survey conducted between 2010 and 2014 for analysis of the latest situation of inequality, and 28 countries with a survey also conducted between 2000 and 2004 for analysis of the change in inequality over time. Participants Women aged 15-49 years with a live birth during the two or three years preceding the survey. Main outcome measures Data on caesarean section were disaggregated by asset based household wealth status and presented separately for five subgroups, ranging from the poorest to the richest fifth. Absolute and relative inequalities were measured using difference and ratio measures. The pace of change in the poorest and richest fifths was compared using a measure of excess change. Results National caesarean section rates ranged from 0.6% in South Sudan to 58.9% in the Dominican Republic. Within countries, caesarean section rates were lowest in the poorest fifth (median 3.7%) and highest in the richest fifth (median 18.4%). 18 out of 72 study countries reported a difference of 20 percentage points or higher between the richest and poorest fifth. The highest caesarean section rates and greatest levels of absolute inequality were observed in countries from the region of the Americas, whereas countries from the African region had low levels of caesarean use and comparatively lower levels of absolute inequality, although relative inequality was quite high in some countries. 26 out of 28 countries reported increases in caesarean section rates over time. Rates tended to increase faster in the richest fifth (median 0.9 percentage points per year) compared with the poorest fifth (median 0.2 percentage points per year), indicating an increase in inequality over time in most of these countries

The narrative of caesarean birth appears on several occasions in Greek mythology: in the birth of Dionysus is the God of the grape harvest and winemaking and wine; in the birth of Asclepius the God of medicine and healing; and in the birth of Adonis the God of beauty and desire. It is possible, however not obligatory, that it was not solely a fantasy but also reflected a contemporary medical practice.

Wound complications remain a significant source of morbidity for patients undergoing open infra-inguinal re-vascularization. The purpose of this study was to determine the impact of several infection-control strategies on post-operative wound complications after open infra-inguinal re-vascularization. A retrospective cohort study was conducted among all patients who underwent an open infra-inguinal re-vascularization procedure before and after 2014. Since 2014, we have implemented strategies to reduce post-operative wound complications, including: (1) Decreasing the use of incisional skin staples, (2) increasing the use of negative pressure wound therapy (NPWT) dressings, and (3) implementing an outpatient elective decontamination protocol for methicillin-resistant Staphylococcus aureus. "Pre-era" is defined as the period between January 2012 and December 2013, before the implementation of infection control strategies; "Post-era" is between January 2015 and August 2016, after implementation. The primary outcome of interest is 30-day wound complications (infection or dehiscence). Multi-variable logistic regression analysis was used to identify significant predictors of wound-related complications between the two cohorts. Propensity score adjustment controlled for baseline patient characteristics, peri-operative variables, and surgeon experience. A total of 338 open infra-inguinal procedures were performed: 175 in the pre-era and 163 in the post-era. Chlorhexidine skin preparation was used in the majority (321 [95%]) of cases. Comparing the periods, the post-era is characterized by a significant decrease in the use of groin staples (118 [67%] vs. 51 [31%], p < 0.001), and an increased application of NPWT dressings (6 [4%] vs. 66 [43%], p < 0.001). Thirty-five (37%) outpatient elective cases received the pre-operative decontamination protocol in the post-era. Compared with the pre-era, there was a decrease in the 30-day rate of wound complications (68 [39%] to

Recent conflicts have been characterised by the use of improvised explosive devices causing devastating injuries, including heavily contaminated wounds requiring meticulous surgical debridement. After being rendered surgical clean, these wounds are dressed and the patient transferred back to the UK for on-going treatment. A dressing that would prevent wounds from becoming colonised during transit would be desirable. The aim of this study was to establish whether using nanocrystalline silver dressings, as an adjunct to the initial debridement, would positively affect wound microbiology and wound healing compared to standard plain gauze dressings. Patients were prospectively randomised to receive either silver dressings, in a nanocrystalline preparation (Acticoat™), or standard of care dressings (plain gauze) following their initial debridement in the field hospital. On repatriation to the UK microbiological swabs were taken from the dressing and the wound, and an odour score recorded. Wounds were followed prospectively and time to wound healing was recorded. Additionally, patient demographic data were recorded, as well as the mechanism of injury and Injury Severity Score. 76 patients were recruited to the trial between February 2010 and February 2012. 39 received current dressings and 37 received the trial dressings. Eleven patients were not swabbed. There was no difference (p=0.1384, Fishers) in the primary outcome measure of wound colonisation between the treatment arm (14/33) and the control arm (20/32). Similarly time to wound healing was not statistically different (p=0.5009, Mann-Whitney). Wounds in the control group were scored as being significantly more malodorous (p=0.002, Mann-Whitney) than those in the treatment arm. This is the first randomised controlled trial to report results from an active theatre of war. Performing research under these conditions poses additional challenges to military clinicians.

Although it has been performed in a modern context for about 100 years, there is no concise analysis of the international architecture of caesarean section research output available so far. Therefore, the present study characterizes the global pattern of the related publications by using the NewQIS (New Quality and Quantity Indices in Science) platform, which combines scientometric methods with density equalizing mapping algorithms. The Web of Science was used as a database. 12,608 publications were identified that originated from 131 countries. The leading nations concerning research activity, overall citations and country-specific h-Index were the USA and the United Kingdom. Relation of the research activity to epidemiologic data indicated that Scandinavian countries including Sweden and Finland were leading the field, whereas, in relation to economic data, countries such as Israel and Ireland led. Semi-qualitative indices such as country-specific citation rates ranked Sweden, Norway and Finland in the top positions. International caesarean section research output continues to grow annually in an era where caesarean section rates increased dramatically over the past decades. With regard to increasing employment of scientometric indicators in performance assessment, these findings should provide useful information for those tasked with the improvement of scientific achievements.

Dermatopathologists assess wounds secondary to trauma, infection, or oncologic resection that can be challenging to reconstruct. OASIS Ultra, an extracellular matrix, has been described for use in chronic and burn wounds. The aim of this pilot study is to assess wound healing in post-traumatic and infective wounds treated with OASIS using histological markers of repair. Adults with traumatic, infective or iatrogenic wound defects with size precluding primary closure were eligible. Half the wound was randomly assigned to receive OASIS plus standard therapy; the other half received standard of care (SOC) therapy. During dressing changes, standardized-scale photographs were taken and biopsies obtained. Histologic sections were reviewed for degree of acute inflammation and extent of tissue repair. Neutrophils, edema, hemorrhage, necrosis, fibroblasts, collagen density and neovascularization were semi-quantitatively assessed. Forty-four skin biopsies from 7 patients with 10 acute wounds met eligibility criteria. Histologically, OASIS samples demonstrated improved acute inflammation scores compared to SOC. No patients experienced OASIS-related complications. OASIS-treated wound halves trended toward more wound contraction and improved tissue repair. Our scoring system aids histopathological wound assessment. Treatment of critical-sized, post-traumatic, acute wounds with OASIS resulted in decreased inflammation, and potentially more advanced wound healing, compared to SOC. © 2017 John Wiley & Sons A/S.

Halvorsen, Lotta; Nerum, Hilde; Sørlie, Tore; Oian, Pål

2010-02-01

the attitudes of two counsellors towards women requesting a caesarean section due to fear of birth were identified. One emphasised the ability to overcome any emotional obstacle to vaginal birth ('coping attitude'), and the other emphasised that the ultimate choice of mode of birth was the womans' ('autonomy attitude'). Two research questions were asked: (1) What are the predictors of change in a wish for a caesarean and of vaginal birth in women with fear of birth? (2) Does a change from an 'autonomy attitude' to a 'coping attitude' increase the number of women who change their request for a caesarean and who give birth vaginally? the study population consisted of two samples of pregnant women with fear of birth and concurrent request for a caesarean, referred for crisis-oriented counselling at the antenatal clinic, University Hospital of North Norway between 2000-2002 (n=86) and 2004-2006 (n=107). Data were gathered from referral letters, counseling and antenatal, intra- and postpartum records. a coping attitude of the counsellor was positively associated with change in the request for a caesarean and with vaginal birth. A change from an autonomy attitude to a coping attitude was associated with a significant increase in the percentage of women who changed their desire for a caesarean from 77 to 93, and who had a vaginal birth from 42 to 81. a coping attitude was strongly associated with change in the desire for a caesarean and giving birth vaginally. A coping attitude can be learned through critical reflection and awareness of the counsellor's attitude, with measurable clinical results. Copyright 2008 Elsevier Ltd. All rights reserved.

We recently performed proteomic characterization of a modified collagen gel (MCG) dressing and reported promising effects of the gel in healing full-thickness excisional wounds. In this work, we test the translational relevance of our aforesaid findings by testing the dressing in a swine model of chronic ischemic wounds recently reported by our laboratory. Full-thickness excisional wounds were established in the center of bipedicle ischemic skin flaps on the backs of animals. Ischemia was verified by laser Doppler imaging, and MCG was applied to the test group of wounds. Seven days post wounding, macrophage recruitment to the wound was significantly higher in MCG-treated ischemic wounds. In vitro, MCG up-regulated expression of Mrc-1 (a reparative M2 macrophage marker) and induced the expression of anti-inflammatory cytokine interleukin (IL)-10 and of fibroblast growth factor-basic (β-FGF). An increased expression of CCR2, an M2 macrophage marker, was noted in the macrophages from MCG treated wounds. Furthermore, analyses of wound tissues 7 days post wounding showed up-regulation of transforming growth factor-β, vascular endothelial growth factor, von Willebrand's factor, and collagen type I expression in MCG-treated ischemic wounds. At 21 days post wounding, MCG-treated ischemic wounds displayed higher abundance of proliferating endothelial cells that formed mature vascular structures and increased blood flow to the wound. Fibroblast count was markedly higher in MCG-treated ischemic wound-edge tissue. In addition, MCG-treated wound-edge tissues displayed higher abundance of mature collagen with increased collagen type I : III deposition. Taken together, MCG helped mount a more robust inflammatory response that resolved in a timely manner, followed by an enhanced proliferative phase, angiogenic outcome, and postwound tissue remodeling. Findings of the current study warrant clinical testing of MCG in a setting of ischemic chronic wounds. © 2014 by the Wound

Wound drains following thyroid surgery.

The nature and indications for thyroid surgery vary and a perceived risk of haemorrhage post-surgery is one reason why wound drains are frequently inserted. However when a significant bleed occurs, wound drains may become blocked and the drain does not obviate the need for surgery or meticulous haemostasis. The evidence in support of the use of drains post-thyroid surgery is unclear therefore and a systematic review of the best available evidence was undertaken. To determine the effects of inserting a wound drain during thyroid surgery, on wound complications, respiratory complications and mortality. We searched the following databases: Cochrane Wounds Group Specialised Register and the Cochrane Central Register of Controlled Trials (CENTRAL) (issue 1, 2007); MEDLINE (2005 to February 2007); EMBASE (2005 to February 2007); CINAHL (2005 to February 2007) using relevant search strategies. Only randomised controlled trials were eligible for inclusion. Quasi randomised studies were excluded. Studies with participants undergoing any form of thyroid surgery, irrespective of indications, were eligible for inclusion in this review. Studies involving people undergoing parathyroid surgery and lateral neck dissections were excluded. At least 80% follow up (till discharge) was considered essential. Studies were assessed for eligibility and data were extracted by two authors independently, differences were resolved by discussion. Studies were assessed for validity including criteria on whether they used a robust method of random sequence generation and allocation concealment. Missing and unclear data were resolved by contacting the study authors. 13 eligible studies were identified (1646 participants). 11 studies compared drainage with no drainage and found no significant difference in re-operation rates; incidence of respiratory distress and wound infections. Post-operative wound collections needing aspiration or drainage were significantly reduced by drains (RR 0.51, 95% CI 0

Neurologic complications of post-partum are serious and usually secondary to eclampsia or stroke. We here report a 26-year-old female who presented with severe headaches, blurred vision, and repeated generalized seizures secondary to posterior reversible encephalopathy that occurred after a caesarean section for fetal death in utero. Outcome was favourable. Although uncommon, this neurologic complication of the post-partum should be discussed in the presence of any sign of encephalopathy occurring in the context of acute hypertension.

To evaluate whether women with a caesarean section at their first delivery have an increased risk of retained placenta at their second delivery. Population-based cohort study. Sweden. All women with their first and second singleton deliveries in Sweden during the years 1994-2006 (n = 258,608). Women with caesarean section or placental abruption in their second pregnancy were not included in the study population. The risk of retained placenta at second delivery was estimated for women with a first delivery by caesarean section (n = 19,458), using women with a first vaginal delivery as reference (n = 239,150). Risks were calculated as odds ratios by unconditional logistic regression analysis with 95% confidence intervals (95%) after adjustments for maternal, delivery, and infant characteristics. Retained placenta with normal (≤1000 ml) and heavy (>1000 ml) bleeding. The overall rate of retained placenta was 2.07%. In women with a previous caesarean section and in women with previous vaginal delivery, the corresponding rates were 3.44% and 1.96%, respectively. Compared with women with a previous vaginal delivery, women with a previous caesarean section had an increased risk of retained placenta (adjusted OR 1.45; 95% CI 1.32-1.59), and the association was more pronounced for retained placenta with heavy bleeding (adjusted OR 1.61; 95% CI 1.44-1.79). Our report shows an increased risk for retained placenta in women previously delivered by caesarean section, a finding that should be considered in discussions of mode of delivery. © 2013 Royal College of Obstetricians and Gynaecologists.

We report on a study to assess the feasibility of a swept source-based speckle variance optical coherence tomography setup for monitoring cutaneous microvasculature. Punch wounds created in the ear pinnae of diabetic mice were monitored at different times post wounding to assess the structural and vascular changes. It was observed that the epithelium thickness increases post wounding and continues to be thick even after healing. Also, the wound size assessed by vascular images is larger than the physical wound size. The results show that the developed speckle variance optical coherence tomography system can be used to monitor vascular regeneration during wound healing in diabetic mice.

Wound Healing Essentials: Let There Be Oxygen

The state of wound oxygenation is a key determinant of healing outcomes. From a diagnostic standpoint, measurements of wound oxygenation are commonly used to guide treatment planning such as amputation decision. In preventive applications, optimizing wound perfusion and providing supplemental O2 in the peri-operative period reduces the incidence of post-operative infections. Correction of wound pO2 may, by itself, trigger some healing responses. Importantly, approaches to correct wound pO2 favorably influence outcomes of other therapies such as responsiveness to growth factors and acceptance of grafts. Chronic ischemic wounds are essentially hypoxic. Primarily based on the tumor literature, hypoxia is generally viewed as being angiogenic. This is true with the condition that hypoxia be acute and mild to modest in magnitude. Extreme near-anoxic hypoxia, as commonly noted in problem wounds, is not compatible with tissue repair. Adequate wound tissue oxygenation is required but may not be sufficient to favorably influence healing outcomes. Success in wound care may be improved by a personalized health care approach. The key lies in our ability to specifically identify the key limitations of a given wound and in developing a multifaceted strategy to specifically address those limitations. In considering approaches to oxygenate the wound tissue it is important to recognize that both too little as well as too much may impede the healing process. Oxygen dosing based on the specific need of a wound therefore seems prudent. Therapeutic approaches targeting the oxygen sensing and redox signaling pathways are promising. PMID:19152646

Objectives. We aimed to assess if Caesarean section is a risk factor for overnutrition in early- and late-childhood, and to assess the magnitude of the effect of child- versus family-related variables in these risk estimates. Methods. Longitudinal data from Peruvian children from the Young Lives Study was used. Outcomes assessed were overweight, obesity, overnutrition (overweight plus obesity), and central obesity (waist circumference) at the age 5 (first follow-up) and 7 (second follow-up) years. The exposure of interests was delivery by Caesarean section. Relative risks (RR) and 95% confidence intervals (95% CI) were calculated using multivariable models adjusted for child-related (e.g., birth weight) and family-related (e.g., maternal nutritional status) variables. Results. At baseline, mean age was 11.7 (± 3.5) months and 50.1% were boys. Children born by Caesarean section were 15.6%. The 10.5% of the children were overweight and 2.4% were obese. For the obesity outcome, data from 6,038 and 9,625 children-years was included from baseline to the first and second follow-up, respectively. Compared to those who did not experience Caesarean delivery, the risk of having obesity was higher in the group born by Caesarean: RRs were higher at early-childhood (first follow-up: 2.25; 95% CI [1.36-3.74]) than later in life (second follow-up: 1.57; 95% CI [1.02-2.41]). Family-related variables had a greater effect in attenuating the risk estimates for obesity at the first, than at the second follow-up. Conclusion. Our results suggest a higher probability of developing obesity, but not overweight, among children born by Caesarean section delivery. The magnitude of risk estimates decreased over time, and family-related variables had a stronger effect on the risk estimates at early-childhood.

Joint effect of education and age at childbirth on the risk of caesarean delivery: findings from Germany 2008-2015.

This article aims at assessing the joint effect of maternal age and education on the risk of having a caesarean delivery. As high maternal education is often associated with lower caesarean-birth rates, but high-educated women tend to postpone motherhood, these effects may offset each other in traditional analyses. Secondary analysis of the data from the German Family Panel pairfam. The interview-based data refer to 1020 births between 2008 and 2015. We analyse only reports from mothers and calculate logistic regression models. The caesarean delivery rate differs strongly between education levels, and low-educated women are at higher risk of having a caesarean delivery when controlling for parity and age. A positive age gradient is found, indicating a higher risk of caesarean section for older mothers. Without controlling for age, the association of education and caesarean section risk is weaker, i.e., effects of age and education partially level each other out. A model including an interaction term between age and education confirms this result. The risk of having a caesarean delivery does not differ between levels of education when maternal age is not taken into account. Lower maternal education and higher age are both positively associated with the risk of experiencing a caesarean section in Germany. However, as higher educated women tend to have their children later, effects of education and age weigh each other out. Preventive campaigns should target women with lower education and raise women's awareness on the risks associated with late motherhood. Copyright © 2017 The Royal Society for Public Health.

2018-01-01

A 29-year-old patient had undergone an elective lower-segment caesarean section (LSCS) five months previously at a district hospital. The operation and the immediate postoperative period were uneventful. After five months she presented back with a fistulous opening. A fistulogram revealed a connection between the uterus and the skin. Fistulous tract excision was planned. Intraoperatively there was communication between the skin and the uterine cavity, with extensive necrosis of the uterine wall. The patient gave her informed consent for excision of the fistulous tract and/or total abdominal hysterectomy. During surgery, it was deemed that there was no scope for excision, so the decision was made for a total abdominal hysterectomy. Histopathological examination confirmed tuberculosis and the patient responded well to anti-tubercular drugs. This case report describes a rare presentation of tubercular uterocutaneous fistula after caesarean section.

Recent studies show a steep rise in caesarean sections in China. Most couples are now eligible to apply for a second child. This retrospective cohort study compares the prevalence of trial of labour and vaginal birth after caesarean section among Chinese and foreign women in Shanghai. In total, 135 of 368 women underwent trial of labour (36.68%), and of those, 77 (57.04%) had a vaginal birth. After inclusion in a multivariate model, factors associated with trial of labour were maternal age <35 years with an adjusted odds ratio of 2.58 (1.49-4.46), absence of a history of ≥3 abortions (2.22 (1.08-4.57)), and European citizenship (1.94 (1.05-3.59)). The prevalence of trial of labour and vaginal birth seems to mirror rates found in countries of origin, but despite a high rate of caesarean section, Chinese women had a higher rate of vaginal birth after caesarean section than North American and Australian women, in particular. Impact statement What is already known on this subject: Caesarean section (CS) rates are rising worldwide. Repeat CS contributes largely to these rates, although vaginal birth after CS (VBAC) rates varies widely between countries. What the results of this study add: North American and Australian women who deliver in Shanghai have low rates of attempted trial of labour after CS (TOLAC) and VBAC, with European women having the highest rate of TOLAC, followed by Chinese women. Implications for clinical practice and/or further research: These findings might reflect different levels of acceptance in line with respective national trends. Studies evaluating the influence of cultural norms on birth preferences after CS are needed. Further research is also needed to assess the overall acceptance of TOLAC in the context of the softening of the one-child policy in China.

To prepare the ESA (European Space Agency) spaceflight project "Wound healing and Sutures in Unloading Conditions", we studied mechanisms of apoptosis in wound healing models based on ex vivo skin tissue cultures, kept for 10 days alive in serum-free DMEM/F12 medium supplemented with bovine serum albumin, hydrocortisone, insulin, ascorbic acid and antibiotics at 32 °C. The overall goal is to test: (i) the viability of tissue specimens; (ii) the gene expression of activators and inhibitors of apoptosis and extracellular matrix components in wound and suture models; and (iii) to design analytical protocols for future tissue specimens after post-spaceflight download. Hematoxylin-Eosin and Elastica-van-Gieson staining showed a normal skin histology with no signs of necrosis in controls and showed a normal wound suture. TdT-mediated dUTP-biotin nick end labeling for detecting DNA fragmentation revealed no significant apoptosis. No activation of caspase-3 protein was detectable. FASL , FADD , CASP3 , CASP8 , CASP10 , BAX , BCL2 , CYC1 , APAF1 , LAMA3 and SPP1 mRNAs were not altered in epidermis and dermis samples with and without a wound compared to 0 day samples (specimens investigated directly post-surgery). BIRC5 , CASP9 , and FN1 mRNAs were downregulated in epidermis/dermis samples with and/or without a wound compared to 0 day samples. BIRC2 , BIRC3 were upregulated in 10 day wound samples compared to 0 day samples in epidermis/dermis. RELA/FAS mRNAs were elevated in 10 day wound and no wound samples compared to 0 day samples in dermis. In conclusion, we demonstrate that it is possible to maintain live skin tissue cultures for 10 days. The viability analysis showed no significant signs of cell death in wound and suture models. The gene expression analysis demonstrated the interplay of activators and inhibitors of apoptosis and extracellular matrix components, thereby describing important features in ex vivo sutured wound healing models.

To investigate the aesthetic effect of wound repair with flaps. One thousand nine hundred and ninety-six patients with 2082 wounds hospitalized from January 2004 to December 2011. These wounds included 503 deep burn wounds, 268 pressure sores, 392 soft tissue defects caused by trauma, 479 soft tissue defects due to resection of skin cancer and mole removal, 314 soft tissue defects caused by scar excision, and 126 other wounds. Wound area ranged from 1.5 cm x 1.0 cm to 30.0 cm x 22.0 cm. Sliding flaps, expanded flaps, pedicle flaps, and free flaps were used to repair the wounds in accordance with the principle and timing of wound repair with flaps. Five flaps showed venous congestion within 48 hours post-operation, 2 flaps of them improved after local massage. One flap survived after local heparin wet packing and venous bloodletting. One flap survived after emergency surgical embolectomy and bridging with saphenous vein graft. One flap showed partial necrosis and healed after skin grafting. The other flaps survived well. One thousand three hundred and twenty-one patients were followed up for 3 months to 2 years, and flaps of them were satisfactory in shape, color, and elasticity, similar to that of normal skin. Some patients underwent scar revision later with good results. Application of suitable flaps in wound repair will result in quick wound healing, good function recovery, and satisfactory aesthetic effect.

Caesarean section was initially performed to save the lives of the mother and/or her baby. Caesarean section rates have risen substantially worldwide over the past decades. In this study, we set out to compile all available caesarean section rates worldwide at the country level, and to identify the appropriate caesarean section rate at the population level associated with the minimal maternal and neonatal mortality. Ecological study using longitudinal data. Worldwide country-level data. A total of 159 countries were included in the analyses, representing 98.0% of global live births (2005). Nationally representative caesarean section rates from 2000 to 2012 were compiled. We assessed the relationship between caesarean section rates and mortality outcomes, adjusting for socio-economic development by means of human development index (HDI) using fractional polynomial regression models. Maternal mortality ratio and neonatal mortality rate. Most countries have experienced increases in caesarean section rate during the study period. In the unadjusted analysis, there was a negative association between caesarean section rates and mortality outcomes for low caesarean section rates, especially among the least developed countries. After adjusting for HDI, this effect was much smaller and was only observed below a caesarean section rate of 5-10%. No important association between the caesarean section rate and maternal and neonatal mortality was observed when the caesarean section rate exceeded 10%. Although caesarean section is an effective intervention to save maternal and infant lives, based on the available ecological evidence, caesarean section rates higher than around 10% at the population level are not associated with decreases in maternal and neonatal mortality rates, and thus may not be necessary to achieve the lowest maternal and neonatal mortality. The caesarean section rate of around 10% may be the optimal rate to achieve the lowest mortality. © 2015 The Authors

Pharmacokinetics is a first, but essential step to improve population-tailored postoperative analgesia, also after Caesarean delivery. We therefore aimed to quantify the impact of caesarean delivery on the pharmacokinetics of intravenous (iv) paracetamol (2 g, single dose) and iv ketorolac tromethamine (30 mg, single dose) in 2 cohorts eachof 8 women at caesarean delivery and to compare these findings with postpartum to quantify intrapatient changes. We documented a higher median paracetamol clearance at delivery when compared to 10–15 weeks postpartum (11.7 to 6.4 L/h·m2, P < 0.01), even after correction for weight-related changes. Similar conclusions were drawn for ketorolac: median clearance was higher at delivery with a subsequent decrease (2.03 to 1.43 L/h·m2, P < 0.05) in postpartum (17–23 weeks). These differences likely reflect pregnancy- and caesarean-delivery-related changes in drug disposition. Moreover, postpartum paracetamol clearance was significantly lower when compared to estimates published in healthy young volunteers (6.4  versus  9.6 L/h·m2), while this was not the case for ketorolac (1.43  versus  1.48 L/h·m2). This suggests that postpartum is another specific status in young women that merits focused, compound-specific pharmacokinetic evaluation. PMID:22675252

The delivery of cardiac patients is a challenge for the anaesthesiologist, to whom the welfare of both the mother and the foetus is a main issue. In case of caesarean section, advanced monitoring allows to optimize haemodynamic condition and to improve morbidity and mortality. To describe the use of pulse contour analysis calibrated by Trans-pulmonar thermodilution (Picco Plus(®)) for the perioperative management of a caesarean section in a patient with severe cardiomyopathy. We describe the case of a 28-year-old woman with a congenital heart disease who was submitted to a caesarean section under general anaesthesia for maternal pathology and foetal breech presentation. Intra- and post-operative management was optimized by advanced haemodynamic monitorization obtained by pulse contour wave analysis and thermodilution calibration (Picco Plus(®) monitor). The information about preload, myocardial contractility and postcharge was useful in guiding the fluid therapy and the use of vasoactive drugs. This case report illustrates the importance of advanced haemodynamic monitoring with an acceptably invasive device in obstetric patients with high cardiac risk. The increasing experience in advanced haemodynamic management will probably permit to decrease morbidity and mortality of obstetric patients in the future.

The incidence of caesarean section for breech presentation has increased markedly in the last 20 years. A prospective, interventional cohort study was carried out of the success rate of external cephalic version (ECV) and its predictors of as well as its impact on the rate of caesarean section for vaginal breech delivery. All 128 women admitted during the study period to the obstetrics department of a tertiary care military hospital in Taif, Saudi Arabia with breech presentation at term, regardless of age and parity, who accepted ECV were recruited. ECV was successful in 53.9% of the women. Most of the women with successful ECV delivered normally (84.1%) and only 14.5% of them delivered by caesarean section. Conversely, normal vaginal delivery was reported among 8.5% of those who had spontaneous version with failed ECV and approximately two-thirds of them delivered by caesarean section (62.7%). Successful ECV reduced the breech and caesarean section rate.

In this article we focus on the effects of so called non-lethal ammunition. We studied possible mechanism of firearm injury formation as a consequence of using firearm on the body, to present a more comprehensive material in wound ballistics. We pointed out possible actions of a projectile causes on human, respectively other animal organisms, as well as to a manner in which an injury is caused by rifles or shotguns using non-lethal ammunition with rubber projectiles. In the experiment, we have focused on macroscopic analysis of the tissue penetrated by a rubber projectile fired from a long firearm and pump-action shotgun while focusing on the anatomical-morphological analysis of entry wounds to determine the effectiveness respectively, the wounding potential of the projectile. The results of the experiment based on the macroscopic analysis of entry wounds, cavities and exit wounds, show that when a rubber projectile penetrates the body it causes loss of the tissue (i.e. the minus effect) and mechanical disruption of the tissue similar to lethal projectile. Based on the measures and ballistic computations we concluded that in specific cases, like for example in a close range hit, a penetration of vital organs can cause serious or even lethal injuries.

Maternal request for Caesarean section is controversial and yet the NICE Caesarean section Guideline recommends that that if this is requested, following discussion of the risks and benefits, women should be supported in their choice. There was a desire to improve the pathway at Birmingham Women's NHS Foundation Trust. Experience-based co-design methodology uses service user and clinicians experiences collected using qualitative methods to jointly re-design services. Firstly semi-structured interviews were conducted to elicit the views and experiences of health care professionals and women who requested Caesarean section (with and without medical indication). Analysis identified key themes arising from the health care professionals' interviews and 'touch points' (key moments or events related to the experience of care) arising from the interviews with women.. Separate workshops were then held with each group to ensure these resonated and to identify key areas for service improvement. At the first joint workshop a pathway using 'audio clips' demonstrating women's agreed 'touch points' prompted discussion and joint working began to change the pathway. A final second workshop was held to agree changes to the pathway. Interviews were conducted with health care professionals (n = 22, 10 consultant obstetricians and 12 midwives) and women (n = 15). The women's 'touch points' included repetition of request, delay in the decision for Caesarean section to be made, feeling judged, and that information was poor with similar findings identified from the health care professionals. Joint working resulted in a revised pathway for women who request Caesarean section. Changes to the pathway for women as a result of the work include written information about 'The way your baby may be born' which is given to the woman followed by a discussion about mode of birth around the 16 week appointment. If the woman wishes to have a Caesarean section, referral is made to appropriate

The present investigation is an attempt to scientifically validate the traditional use of the roots of the plant Albizzia lebbeck in Ayurvedic system of medicine for curing wounds. The study included phytochemical standardization of the ethanol root extract of A. lebbeck, which was further subjected to oral acute toxicity study. Wound-healing activity of the ethanol root extract was evaluated using incision and excision wound models. Biochemical parameters such as hydroxyproline, hexuronic acid, hexosamine, and antioxidant enzymes like superoxide dismutase, reduced glutathione and free radical parameters including lipid peroxidation and nitric oxide were evaluated on the 10th post-wounding day following dead space method. For confirmation of activity, histopathology of the wounds and granulation tissues from excision and dead space wound model were performed. The study also included assessment of antibacterial activity of ethanol root extract against strains implicated in wound infection. The ethanol root extract was found to be highly rich in flavonoids, saponins, phenols, and tannins, while the amount of rutin was found to be 4.66 % w/w. It significantly increased the wound breaking strength showing a ceiling effect at 500 mg/kg p. o. The ethanol root extract at 500 mg/kg p. o. depicted an optimum wound contraction on the 18th day, while complete wound contraction was observed at the 22nd post wound day. It also demonstrated a significant increase in dry tissue weight, total protein, hydroxyproline, hexosamine, hexuronic acid, superoxide dismutase, and reduced glutathione levels, whereas a decrease in the levels of lipid peroxidation and nitric oxide was also observed with a potential antibacterial activity. Histopathological studies revealed a normal epithelization and fibrosis which was evidenced through an increase in collagen density. Thus, the study scientifically validated the wound-healing activity of the ethanol root extract along with a potential

Life saving or money wasting? Perceptions of caesarean sections among users of services in rural Bangladesh.

Parkhurst, Justin Oliver; Rahman, Syed Azizur

2007-03-01

Bangladesh has a high level of maternal mortality, corresponding to one of the world's lowest rates of use of skilled birth attendance (12.1%), and a similarly low rate of caesarean births (2.4%). While increasing the proportion of women who deliver with professional medical care is essential to prevent maternal deaths, past work has identified distrust of caesarean procedures in Bangladesh. The reasons behind this distrust can manifest itself in health seeking behaviour around maternal care. This paper presents findings from a qualitative study of 30 women in a rural district of Bangladesh who recently delivered in a health facility. It finds that the distrust in doctor's recommendations for surgery stemmed from high costs incurred and a belief that it was used when not medically justified. This could lead to women avoiding or leaving medical facilities in extreme cases. Some women's experiences further illustrated disagreement among medical staff as to whether or not a caesarean procedure should be done, with conflicting financial incentives for doctors to perform caesarean deliveries, and for nurses and midwives to conduct normal deliveries. Policy makers must recognise that the fears women hold of caesarean deliveries may not simply be rooted in ignorance and may, in fact, reflect legitimate concerns with medical practice. Ultimately, it will be essential to address problems in the health systems environment, which may promote improper service provision.

Going public: do risk and choice explain differences in caesarean birth rates between public and private places of birth in Australia?

women who birth in private facilities in Australia are more likely to have a caesarean birth than women who birth in public facilities and these differences remain after accounting for sector differences in the demographic and health risk profiles of women. However, the extent to which women's preferences and/or freedom to choose their mode of birth further account for differences in the likelihood of caesarean birth between the sectors remains untested. women who birthed in Queensland, Australia during a two-week period in 2009 were mailed a self-report survey approximately 3 months after birth. Seven hundred and fifty-seven women provided cross-sectional retrospective data on where they birthed (public or private facility), mode of birth (vaginal or caesarean) and risk factors, along with their preferences and freedom to choose their mode of birth. A hierarchical logistic regression was conducted to determine the extent to which maternal risk and freedom to choose one's mode of birth explain sector differences in the likelihood of having a caesarean birth. while there was no sector difference in women's preference for mode of birth, women who birthed in private facilities had higher odds of feeling able to choose either a vaginal or caesarean birth, and feeling able to choose only a caesarean birth. Women had higher odds of having caesarean birth if they birthed in private facilities, even after accounting for significant risk factors such as age, body mass index, previous caesarean and use of assisted reproductive technology. However, there was no association between place of birth and odds of having a caesarean birth after also accounting for freedom to choose one's mode of birth. these findings call into question suggestions that the higher caesarean birth rate in the private sector in Australia is attributable to increased levels of obstetric risk among women birthing in the private sector or maternal preferences alone. Instead, the determinants of sector

Post-traumatic stress disorder (PTSD) occurs in 1-7% of women following childbirth. While having a caesarean section (C-section) is known to be a significant risk factor for postpartum PTSD, it is currently unknown whether coexisting anaesthesia-related factors are also associated to the disorder. The aim of this study was to assess anaesthesia-linked factors in the development of acute postpartum PTSD. We performed a prospective cohort study on women having a C-section in a tertiary hospital in Switzerland. Patients were followed up six weeks postpartum. Patient and procedure characteristics, past morbidity or traumatic events, psychosocial status and stressful perinatal events were measured. Outcome was divided into two categories: full PTSD disease and PTSD profile. This was based on the number of DSM-IV criteria of the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) present. The PTSD Checklist Scale and the Clinician Administered PTSD Scale were used for measurement. Of the 280 patients included, 217 (77.5%) answered the questionnaires and 175 (62.5%) answered to an additional phone interview. Twenty (9.2%) had a PTSD profile and six (2.7%) a PTSD. When a full predictive model of risk factors for PTSD profile was built using logistic regression, maternal prepartum and intrapartum complications, anaesthetic complications and dissociative experiences during C-section were found to be the significant predictors for PTSD profile. This is the first study to show in parturients having a C-section that an anaesthesia complication is an independent risk factor for postpartum PTSD and PTSD profile development, in addition to known perinatal and maternal risk factors.

Psychological factors have been shown to influence the process of wound healing. This study examined the effect of Mindfulness-Based Stress Reduction (MBSR) on the speed of wound healing. The local production of pro-inflammatory cytokines and growth factors was studied as potential underlying mechanism. Forty-nine adults were randomly allocated to a waiting-list control group (n = 26) or an 8-week MBSR group (n = 23). Pre- and post-intervention/waiting period assessment for both groups consisted of questionnaires. Standardized skin wounds were induced on the forearm using a suction blister method. Primary outcomes were skin permeability and reduction in wound size monitored once a day at day 3, 4, 5, 6, 7, and 10 after injury. Secondary outcomes were cytokines and growth factors and were measured in wound exudates obtained at 3, 6, and 22 h after wounding. Although there was no overall condition effect on skin permeability or wound size, post hoc analyses indicated that larger increases in mindfulness were related to greater reductions in skin permeability 3 and 4 days after wound induction. In addition, MBSR was associated with lower levels of interleukin (IL)-8 and placental growth factor in the wound fluid 22 h after wound induction. These outcomes suggest that increasing mindfulness by MBSR might have beneficial effects on early stages of wound healing. Trial Registration NTR3652, http://www.trialregister.nl.

The purpose of our study was to evaluate the safety and efficacy of transcervical amnioinfusion during labour complicated by meconium-stained amniotic fluid, in a setting with limited peripartum facilities, to lower the incidence of caesarean section. A prospective study was conducted in a teaching hospital in north India, which enrolled 292 patients admitted in labour. Patients were randomly divided into two groups after taking their consent. One group received transcervical amnioinfusion, whilst in the other group amnioinfusion was not done. Caesarean sections were performed in either group if there were foetal heart rate abnormalities (bradycardia or irregularity for 10-20 min) or slow progress of labour. The outcomes studied were the incidence of caesarean sections, duration of maternal hospital stay, maternal febrile morbidity (temperature of >38 degrees C, 24 h after delivery), low Apgar score (at 1 and 5 min), respiratory death, MAS and perinatal mortality. There was a statistically significant reduction in the incidence of caesarean sections in the study group compared to the control group (31 vs. 61%). Amnioinfusion was associated with improved neonatal outcome as evidenced by statistically improved Apgar score at 1 min in newborns in the study group compared to the control group (10 vs. 37.2%). Amnioinfusion during labour was not associated with any significant maternal and neonatal complications. The mean hospital stay of the mother was decreased significantly in the study group patients compared to the control group. Transcervical amnioinfusion in labour for meconium-stained amniotic fluid is a simple, safe and easy-to-perform procedure. It can be performed safely in a setup with limited peripartum facilities, especially in developing countries, to decrease intrapartum operative intervention and reduce foetomaternal morbidity and mortality.

Wound Healing in Patients With Impaired Kidney Function

Renal impairment has long been known to affect wound healing. However, information on differences in the spectrum of wound healing depending on the type of renal insufficiency is limited. Acute kidney injury (AKI) may be observed with different wound types. On one hand, it follows acute traumatic conditions such as crush injury, burns, and post-surgical wounds, and on the other hand, it arises as simultaneous targeting of skin and kidneys by autoimmune-mediated vasculitis. Chronic kidney disease (CKD) and end-stage renal disease (ESRD) often occur in older people, who have limited physical mobility and predisposition for developing pressure-related wounds. The common risk factors for poor wound healing, generally observed in patients with CKD and ESRD, include poorly controlled diabetes mellitus, neuropathy, peripheral vascular disease, chronic venous insufficiency, and aging. ESRD patients have a unique spectrum of wounds related to impaired calcium–phosphorus metabolism, including calciphylaxis, in addition to having the risk factors presented by CKD patients. Overall, there is a wide range of uremic toxins: they may affect local mechanisms of wound healing and also adversely affect the functioning of multiple systems. In the present literature review, we discuss the association between different types of renal impairments and their effects on wound healing and examine this association from different aspects related to the management of wounds in renal impairment patients.

Study of the interrelationships between human and the animals in their environment has always been a subject of interest and caused discoveries of the animal applications in medicine. From the latest century, these remedies called back in traditional medicine of Vietnam and South America and frog skin was used as a biological dressing and had good effects in healing wounds. Also, frog skin secretions have wound healing properties and reduce inflammation. In this study we applied these secretions in the form of ointment to investigate their healing activities. Skin secretions were extracted from Rana ridibunda to evaluate their effects on wound healing in mice. Secretion used as raw extract (RE) and ultrafiltrated extract, using a membrane with cutoff 10kDa as under 10kDa (U10E), was administrated as ointment every 48h on wound site. Control group was left without any treatment and also there was other group treated with ointment (O group) alone. On 2, 4 and 6 days post injury, animals were euthanized and images were taken for wound closure evaluation. Then wound locations were removed for histological assays. Also wound microbial load was examined. Observational parameters including wound closure and wound microbiology in experimental groups compared with the control and O groups have been studied. The results showed U10E group has better effects than RE, O and control groups. Histological parameters, including numbers of inflammatory and fibroblast cells and amount of collagen fibers, neovascularization, as well, represented greater degree of wound healing in U10E group compared with RE, O, and control groups. Our results showed that frog skin secretions were significantly effective in promoting wound healing process. The U10E extract from the frog R. ridibunda possesses a potent accelerating wound healing effect that promises good potential for clinical application in wound care. Further studies will be required to characterize special molecules encompassing

New Zealand guidelines recommend that information regarding childbirth choices be given to women with previous caesarean, so they can make informed decisions about their care. We hypothesised that rates of trial of labour (TOL) and vaginal birth after caesarean (VBAC) would vary by women's ethnicity. To estimate the association of ethnicity with TOL and VBAC rates. Clinical data were used to identify women who gave birth at Auckland Hospital in 2006-2009 with history of previous caesarean eligible for TOL. Multivariable models were used to estimate the association of women's characteristics (ethnicity, age, socio-economic status (SES), height, body mass index, lead maternity carer, diabetes, hypertension, haemorrhage, labour induction, gestational age) with rates of TOL and VBAC. In the study cohort of 2400 women, the TOL rate was 39.5%; the VBAC rate was 57.4%. Pacific women were twice as likely to have TOL, while Asian and non-New Zealand European women were half as likely to have VBAC, compared with New Zealand European women. Women in more deprived areas were more likely to have TOL, but SES was not associated with VBAC rates. Women under the care of private obstetricians were least likely to have TOL or VBAC. There are ethnic disparities in TOL and VBAC rates at our hospital. Strategies need to be developed to ensure that women of all ethnicities have access to both options for mode of delivery. © 2013 The Authors ANZJOG © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Standardized and reproducible animal models are crucial in medical research. Rodents are commonly used in wound healing studies since, they are easily available, affordable and simple to handle and house. However, the most significant limitation of rodent models is that the wounds heal by contraction while in humans the primary mechanisms of healing are reepithelialization and granulation tissue formation. The robust contraction results in faster wound closure that complicates the reproducibility of rodent studies in clinical trials. We have developed a titanium wound chamber for rodent wound healing research. The chamber is engineered from two pieces of titanium and is placed transcutaneously on the dorsum of a rodent. The chamber inhibits wound contraction and provides a means for controlled monitoring and sampling of the wound environment in vivo with minimal foreign body reaction. This technical report introduces two modalities utilizing the titanium chambers in rats: (1) Wound in a skin island model and, (2) Wound without skin model. Here, we demonstrate in rats how the "wound in a skin island model" slows down wound contraction and how the "wound without skin" model completely prevents the closure. The titanium wound chamber provides a reproducible standardized models for wound healing research in rodents. © 2016 by the Wound Healing Society.

Successful wound healing depends on various factors, including exudate control, prevention of microbial contaminants, and moisture balance. We report two cases of managing burn wounds with SMARTPORE Technology polyurethane foam dressing. In Case 1, a 2-year-old Asian girl presented with a delayed (11 days) wound on her right leg. She sustained a thermal injury from a hot iron that was left idle on the floor. Clinical inspection revealed an infected wound with overlying eschar that traversed her knee joint. As her parents refused surgical debridement under general anesthesia, hydrotherapy and wound dressing using SMARTPORE Technology Polyurethane foam were used. Despite the delay in presentation of this linear thermal pediatric burn injury that crossed the knee joint, the patient's response to treatment and its outcome were highly encouraging. She was cooperative and tolerated each dressing change without the need of supplemental analgesia. Her wound was healed by 24 days post-admission. In Case 2, a 25-year-old Asian man presented with a mixed thickness thermal flame burn on his left leg. On examination, the injury was a mix of deep and superficial partial thickness burn, comprising approximately 3% of his total body surface area. SMARTPORE Technology polyurethane foam was used on his wound; his response to the treatment was very encouraging as the dressing facilitated physiotherapy and mobility. The patient rated the pain during dressing change as 2 on a scale of 10 and his pain score remained the same in every subsequent change. His wound showed evidence of epithelialization by day 7 post-burn. There were no adverse events reported. Managing burn wounds with SMARTPORE Technology polyurethane foam resulted in reduced pain during dressing changes and the successful healing of partial and mixed thickness wounds. The use of SMARTPORE Technology polyurethane foam dressings showed encouraging results and requires further research as a desirable management option in

Hemostasis is a fundamental management issue post-operatively in minor oral surgical procedures. To ensure safety and therapeutic efficacy in patients, under oral anti coagulant therapy, is complicated by necessity for frequent determination of prothrombin time or international normalised ratio. The aim of the study was to determine whether early hemostasis achieved by using Hemcon Dental Dressing (HDD) will affect post-operative care and surgical healing outcome in minor oral surgical procedures. A total of 30 patients, aged 18 years to 90 years, except those allergic to seafood, who consented to participate, were enrolled into this study. Patients were required to have two or more surgical sites so that they would have both surgical and control sites. All patients taking Oral Anticoagulation Therapy (OAT) were included for treatment in the study without altering the anticoagulant regimens. Institutional Review Board approval was obtained for the same. The collected data was subjected to statistical analysis using unpaired t-test. All HDD surgically treated sites achieved hemostasis in 1.49 minutes and control wounds in 4.06 minutes (p < 0.001). Post-operative pain at HDD treated sites (1.87,1.27 on 1 st and 3 rd day respectively) was significantly lower than the control sites (4.0,1.87 on 1 st and 3 rd day respectively) p-value (0.001, 0.001 respectively). HDD treated oral surgery wounds achieved statistically significant improved healing both at 1 st and 3 rd post-operative days (p <0.0001). The HDD has been proven to be a clinically effective hemostatic dressing material that significantly shortens bleeding time following minor oral surgical procedures under local anaesthesia, including those patients taking OAT. Patients receiving the HDD had improved surgical wound healing as compared to controls.

Background Elective repeat caesarean delivery (ERCD) rates have been increasing worldwide, thus prompting obstetric discourse on the risks and benefits for the mother and infant. Yet, these increasing rates also have major economic implications for the health care system. Given the dearth of information on the cost-effectiveness related to mode of delivery, the aim of this paper was to perform an economic evaluation on the costs and short-term maternal health consequences associated with a trial of labour after one previous caesarean delivery compared with ERCD for low risk women in Ireland. Methods Using a decision analytic model, a cost-effectiveness analysis (CEA) was performed where the measure of health gain was quality-adjusted life years (QALYs) over a six-week time horizon. A review of international literature was conducted to derive representative estimates of adverse maternal health outcomes following a trial of labour after caesarean (TOLAC) and ERCD. Delivery/procedure costs derived from primary data collection and combined both “bottom-up” and “top-down” costing estimations. Results Maternal morbidities emerged in twice as many cases in the TOLAC group than the ERCD group. However, a TOLAC was found to be the most-effective method of delivery because it was substantially less expensive than ERCD (€1,835.06 versus €4,039.87 per women, respectively), and QALYs were modestly higher (0.84 versus 0.70). Our findings were supported by probabilistic sensitivity analysis. Conclusions Clinicians need to be well informed of the benefits and risks of TOLAC among low risk women. Ideally, clinician-patient discourse would address differences in length of hospital stay and postpartum recovery time. While it is premature advocate a policy of TOLAC across maternity units, the results of the study prompt further analysis and repeat iterations, encouraging future studies to synthesis previous research and new and relevant evidence under a single

Does a primary Caesarean section influence the rate of, and time to, subsequent live birth compared with vaginal delivery? Caesarean section was associated with a reduction in the rate of subsequent live birth, particularly among elective and maternal-requested Caesareans indicating maternal choice plays a role. Several studies have examined the relationship between Caesarean section and subsequent birth rate with conflicting results primarily due to poor epidemiological methods. This Danish population register-based cohort study covered the period from 1982 to 2010 (N = 832 996). All women with index live births were followed until their subsequent live birth or censored (maternal death, emigration or study end) using Cox regression models. In all 577 830 (69%) women had a subsequent live birth. Women with any type of Caesarean had a reduced rate of subsequent live birth (hazard ratio [HR] 0.86, 95% confidence intervals [CI] 0.85, 0.87) compared with spontaneous vaginal delivery. This effect was consistent when analyses were stratified by type of Caesarean: emergency (HR 0.87, 95% CI 0.86, 0.88), elective (HR 0.83, 95% CI 0.82, 0.84) and maternal-requested (HR 0.61, 95% CI 0.57, 0.66) and in the extensive sub-analyses performed. Lack of biological data to measure a woman's fertility is a major limitation of the current study. Unmeasured confounding and limited availability of data (maternal BMI, smoking, access to fertility services and maternal-requested Caesarean section) as well as changes in maternity care over time may also influence the findings. This is the largest study to date and shows that Caesarean section is most likely not causally related to a reduction in fertility. Maternal choice to delay or avoid childbirth is the most plausible explanation. Our findings are generalizable to other middle- to high-income countries; however, cross country variations in Caesarean section rates and social or cultural differences are acknowledged.

To determine the effects of two computer based decision aids on decisional conflict and mode of delivery among pregnant women with a previous caesarean section. Randomised trial, conducted from May 2004 to August 2006. Four maternity units in south west England, and Scotland. 742 pregnant women with one previous lower segment caesarean section and delivery expected at >or=37 weeks. Non-English speakers were excluded. Usual care: standard care given by obstetric and midwifery staff. Information programme: women navigated through descriptions and probabilities of clinical outcomes for mother and baby associated with planned vaginal birth, elective caesarean section, and emergency caesarean section. Decision analysis: mode of delivery was recommended based on utility assessments performed by the woman combined with probabilities of clinical outcomes within a concealed decision tree. Both interventions were delivered via a laptop computer after brief instructions from a researcher. Total score on decisional conflict scale, and mode of delivery. Women in the information programme (adjusted difference -6.2, 95% confidence interval -8.7 to -3.7) and the decision analysis (-4.0, -6.5 to -1.5) groups had reduced decisional conflict compared with women in the usual care group. The rate of vaginal birth was higher for women in the decision analysis group compared with the usual care group (37% v 30%, adjusted odds ratio 1.42, 0.94 to 2.14), but the rates were similar in the information programme and usual care groups. Decision aids can help women who have had a previous caesarean section to decide on mode of delivery in a subsequent pregnancy. The decision analysis approach might substantially affect national rates of caesarean section. Trial Registration Current Controlled Trials ISRCTN84367722.

We investigated block heights that anaesthetists considered adequate for caesarean section to proceed under spinal anaesthesia. During 3 months, 15 obstetric anaesthetists recorded block height to touch, pinprick or cold when spinal anaesthesia was considered satisfactory for caesarean section to proceed. Median (IQR [range]) block height for touch, pinprick, first cold and icy were: T10 (T7-T12 [T3-L1]); T5 (T4-T6 [C7-L1]); T5 (T4-T6 [C7-L1]); and T3 (T2-T4 [C7-L1]), respectively. Modalities were significantly correlated for: touch and cold, p = 0.0001; touch and icy, p = 0.0007; touch and pinprick, p = 0.0018; cold and icy, p < 0.0001; cold and pinprick, p = 0.0001; icy and pinprick, p < 0.0001. Pairwise comparisons showed differences between all modalities (p < 0.001) apart from pinprick and first cold (p = 0.94). All women had satisfactory anaesthesia despite 76 (81%) having a block to touch below T6. Single modality assessment of block height, particularly using touch, may erroneously indicate inadequate anaesthesia for caesarean section.

The delivery of a macrosomic infant is associated with a higher risk for maternofoetal complications. Shoulder dystocia is the most feared fetal complication, leading sometimes to a disproportionate use of caesarean section. This study aims to evaluate the interest of preventive caesarean section. We conducted a retrospective study of 400 macrosomic births between February 2010 and December 2012. We also identified cases of infants with shoulder dystocia occurred in 2012 as well as their respective birthweight. Macrosomic infants weighed between 4000g and 4500g in 86.25% of cases and between 4500 and 5000 in 12.25% of cases. Vaginal delivery was performed in 68% of cases. Out of 400 macrosomic births, 9 cases with shoulder dystocia were recorded (2.25%). All of these cases occurred during vaginal delivery. The risk for shoulder dystocia invaginal delivery has increased significantly with the increase in birth weight (p <10-4). The risk for elongation of the brachial plexus was 11 per thousand vaginal deliveries of macrosomic infants. This risk was not correlated with birthweight (p = 0.38). The risk for post-traumatic sequelae was 0.71%. Shoulder dystocia affectd macrosoic infants in 58% of cases. Shoulder dystocia is not a complication exclusively associated with macrosomia. Screening for risky deliveries and increasing training of obstetricians on maneuvers in shoulder dystocia seem to be the best way to avoid complications.

Differential attentional responding in caesarean versus vaginally delivered infants.

PubMed

Adler, Scott A; Wong-Kee-You, Audrey M B

2015-11-01

Little is known about the role that the birth experience plays in brain and cognitive development. Recent research has suggested that birth experience influences the development of the somatosensory cortex, an area involved in spatial attention to sensory information. In this study, we explored whether differences in spatial attention would occur in infants who had different birth experiences, as occurs for caesarean versus vaginal delivery. Three-month-old infants performed either a spatial cueing task or a visual expectation task. We showed that caesarean-delivered infants' stimulus-driven, reflexive attention was slowed relative to vaginally delivered infants', whereas their cognitively driven, voluntary attention was unaffected. Thus, types of birth experience influence at least one form of infants' attention, and possibly any cognitive process that relies on spatial attention. This study also suggests that birth experience influences the initial state of brain functioning and, consequently, should be considered in our understanding of brain development.

Immediate or early skin-to-skin contact after a Caesarean section: a review of the literature.

The World Health Organization and the United Nations International Children's Emergency Fund recommends that mothers and newborns have skin-to-skin contact immediately after a vaginal birth, and as soon as the mother is alert and responsive after a Caesarean section. Skin-to-skin contact can be defined as placing a naked infant onto the bare chest of the mother. Caesarean birth is known to reduce initiation of breastfeeding, increase the length of time before the first breastfeed, reduce the incidence of exclusive breastfeeding, significantly delay the onset of lactation and increase the likelihood of supplementation. The aim of this review is to evaluate evidence on the facilitation of immediate (within minutes) or early (within 1 h) skin-to-skin contact following Caesarean section for healthy mothers and their healthy term newborns, and identify facilitators, barriers and associated maternal and newborn outcomes. A range of electronic databases were searched for papers reporting research findings published in English between January 2003 and October 2013. Seven papers met the criteria. This review has provided some evidence that with appropriate collaboration skin-to-skin contact during Caesarean surgery can be implemented. Further evidence was provided, albeit limited, that immediate or early skin-to-skin contact after a Caesarean section may increase breastfeeding initiation, decrease time to the first breastfeed, reduce formula supplementation in hospital, increase bonding and maternal satisfaction, maintain the temperature of newborns and reduce newborn stress. © 2014 John Wiley & Sons Ltd.

The optimal local-anaesthetic (LA) dose for transversus-abdominis-plane (TAP) block is unclear. In this meta-analysis, we aimed to determine whether TAP blocks for Caesarean delivery (CD) with low-dose (LD) LA demonstrated non-inferiority in terms of analgesic efficacy, compared with high-dose (HD) LA. A literature search was performed for randomised controlled trials examining the analgesic efficacy of TAP blocks vs control after CD. The different dosing used in these studies was classified as HD or LD (bupivacaine equivalents >50 or ≤50 mg per block side, respectively). The pooled results of each dose group vs control were indirectly compared using the Q test. The primary outcome was 24 h opioid consumption. Secondary outcomes included 6 and 24 h postoperative pain scores, time to first analgesia, 6 h opioid consumption, opioid-related side-effects, and maternal satisfaction. Fourteen studies consisting of 770 women (389 TAP and 381 control) were included. Compared with controls, the 24 h opioid consumption (milligram morphine equivalents) was lower in HD [mean difference (MD) 95% confidence interval (CI) -22.41 (-38.56, -6.26); P=0.007; I 2 =93%] and LD [MD 95% CI -16.29 (-29.74, -2.84); P=0.02; I 2 =98%] TAP groups. However, no differences were demonstrated between the HD and LD groups (P=0.57). There were also no differences between the HD and LD groups for the 6 h opioid consumption, time to first analgesia, 6 and 24 h pain scores, postoperative nausea and vomiting, pruritus, and maternal satisfaction. Low-dose TAP blocks for Caesarean delivery provide analgesia and opioid-sparing effects comparable with the high-dose blocks. This suggests that lower doses can be used to reduce local anaesthetic toxicity risk without compromising the analgesic efficacy. Copyright © 2017 British Journal of Anaesthesia.

The purpose of this study was to evaluate the prevalence and predictors of post-Loop Electrosurgical Excision Procedure (LEEP) complications in Srinagarind Hospital, Khon Kaen, Thailand. Retrospective chart review was performed for 200 patients undergoing LEEP during January 2012 to February 2013. Their mean age was 45 years-old. Fifty-three (26.5%) were menopausal. The three most common preceding abnormal cervical cytology were high-grade squamous intraepithelial lesion (HSIL; 50%), atypical squamous cell cannot exclude HSIL (ASC-H; 10.5%), and low-grade squamous intraepithelial lesion (LSIL; 10%). The overall complications prevalence rate was 16.5% (95%CI, 11.4-21.6). Complications included bleeding (11%; 95%CI, 6.66-15.3), offensive discharge (4%; 95%CI, 1.28-6.72), and pelvic inflammatory disease (1.5%; 95%CI, 0.18-3.18). Only mode of delivery was an independent predictor of post-LEEP complications. Women with previous caesarean sections carried an increased risk of complications by 3.9 times (95%CI, 1.21-12.56) compared with vaginal delivery. In conclusion, LEEP is generally safe with an acceptable complication rate. Previous caesarean section was the only independent predictor for post-LEEP complications. However, this predictor still needs prudent evaluation as no clear cause-effect relationship was identified.

Healing of burn wounds is often associated with scar formation due to excessive inflammation and delayed wound closure. To date, no effective treatment is available to prevent the fibrotic process. The Renin Angiotensin System (RAS) was shown to be involved in fibrosis in various organs. Statins (e.g. Atorvastatin), Angiotensin receptor antagonists (e.g. Losartan) and the combination of these drugs are able to reduce the local RAS activation, and reduced fibrosis in other organs. We investigated whether inhibition of the RAS could improve healing of burn wounds by treatment with Atorvastatin, Losartan or the combination of both drugs. Therefore, full and partial thickness burn wounds were inflicted on both flanks of Yorkshire pigs. Oral administration of Atorvastatin, Losartan or the combination was started at post-burn day 1 and continued for 28 days. Full thickness wounds were excised and transplanted with an autologous meshed split-thickness skin graft at post-burn day 14. Partial thickness wounds received conservative treatment. Atorvastatin treatment resulted in enhanced graft take and wound closure of the full thickness wounds, faster resolution of neutrophils compared to all treatments and reduced alpha-smooth muscle actin positive cells compared to control treatment. Treatment with Losartan and to a lesser extent the combination therapy resulted in diminished graft take, increased wound contraction and poorer scar outcome. In contrast, Losartan treatment in partial thickness wounds decreased the alpha-smooth muscle actin+ fibroblasts and contraction. In conclusion, we showed differential effects of Losartan and Atorvastatin in full and partial thickness wounds. The extensive graft loss seen in Losartan treated wounds is most likely responsible for the poor clinical outcome of these full thickness burn wounds. Therefore, Losartan treatment should not be started before transplantation in order to prevent graft loss. Atorvastatin seems to accelerate the

Myofibroblasts are cells involved on the process of wound contraction, which is smaller on CO2 Laser wounds. The aims of this study were to quantitative and statistically assess the presence of myofibroblasts on both conventional and CO2 Laser wounds. Thirty-two animals (rattus norvegicus) were divided into four groups and operated using either the CO2 Laser (groups A1 and A2) or conventional scalpel (groups B1 and B2). The animals were sacrificed eight days post-operatively (groups: A1 and B1) and 14th days after surgery (groups: A2 and B2). The spec imens we re routinely processed to wax and stained with a-Smooth Muscle Actin (aSMA) and analyzed under light microscopy (40X). Two standard areas around the wound of each slide were selected and used to count the number of myofribroblasts present using a calibrated eyepiece and a graticule. The number of myofibroblasts at day eight was significantly higher than at day 14th. Comparison of the two techniques at day eight showed significant differences between the two groups (Laser, p=0.007 and scalpel, p=0.001). The number of cells present on group B1 was significantly higher than group A1 (p=0.001). However at the 14th day there was no such difference (p=0,072). It is concluded that the small number of myofibroblasts at day eight after wounding with the CO2 Lasermay be the reason why contraction on this wound is smaller than the one observed in conventional surgery.

Calotropis Procera (CP) has been used in the management of toothache, fresh skin burns, gum bleeding as well as others to make it qualify as a medicinal plant. This study was designed to assess its wound-healing property in rabbits and its potentials for anti keloidal activity.Fresh latex of Calotropis were obtained and evaluated phytochemically. Fifteen male rabbits were used and four excisional wounds were created on each rabbit. The rabbits were divided into five groups of three each. Group 1 was the negative control and received no treatment. The wounds of group 2 animals were treated with 2mL of Calotropis latex; group 3 with 2mL honey; and group 4 with a mixture of 1ml honey and 1 mL of the latex. The animals in group 5 were given 2mg triamcinolone intramuscularly. All the groups had their wounds treated daily for 21 days. The wounds' diameters were measured on the day of wound creation, thereafter on days 7, 14 and 21 post wound creation. Biopsies of the wounds were taken on days 3 and 21 and viewed histologically. Phytochemical study of the latex revealed the presence of glycosides, tannins and alkaloids. The wounds were found to be significantly (p<0.05) reduced in groups treated with 50% latex in honey and triamcinolone, respectively, on day 7 post wound creation while there was a significant (p<0.05) reduction in wound surface area in all treated groups on days 14 and 21 post wound creation. Histological findings in untreated group showed thick bundle of collagen fibres some of which had broad based configurations, reminiscent of keloid. The group treated with 2mL of Calotropis latex revealed the presence of florid granulation tissues on day 3 while there was a marked reduction in quantity and size of collagen fibres on day 21 post wound creation which was comparable with what was seen for the triamcinolone-treated group.The general effect of Calotropis latex on wound-healing was noted. Likewise it's similarity to that of triamcinolone, an anti

Although vaginal birth is the safest type of childbirth, sometimes caesarean is necessary for the safety of the mother or the infant. The problem is that low-risk, healthy women are choosing caesarean as a birth option despite the fact that it is fraught with possible complications. To determine the differences and identify the predictors for the way women plan their childbirth based on Health Belief Model. A cross-sectional study was conducted in Bandar abbas city, Iran, from May to October 2015. The study recruited eligible women who self identified themselves as requesting a caesarean or vaginal birth in their response to a questionnaire. Of 470 recruited women, 183 (38.9%) planned to have a caesarean without medical indication. Maternal characteristics (age, level of education, occupational status, involvement in a medical profession, and household income) and obstetric variables (health provider type, place of prenatal care, and the number of children planned for the future) influenced the decisions made by the women. There was a significant difference between women planning a caesarean and those planning vaginal birth in terms of childbirth knowledge. Significant differences were observed regarding maternal self-efficacy, with women planning a caesarean reporting significantly lower self-efficacy than women planning a vaginal birth. Women planning a caesarean birth were also significantly less likely to perceive themselves as being at risk for caesarean-related side effects than women planning a vaginal birth. Comprehensive childbirth knowledge can lead to positive maternal attitude towards vaginal birth and may improve birth confidence. Copyright © 2016 Australian College of Midwives.

This study assessed the lasting impact of dexamethasone (DEX) exposure during early development on tissue repair capacity at later life stages (5, 14, and 24 days post fertilization [dpf]) in zebrafish larvae. Using the caudal fin amputation model, we show that prior exposure to DEX significantly delays but does not prevent wound healing at all life stages studied. DEX-induced impairments on wound healing were fully restored to normal levels with longer post amputation recovery time. Further analyses revealed that DEX mainly exerted its detrimental effects in the early phase (0-5 hours) of wound-healing process. Specifically, we observed the following events: (1) massive amount of cell death both by necrosis and apoptosis; (2) significant reduction in the number as well as misplacement of macrophages at the wound site; (3) aberrant migration and misplacement of neutrophils and macrophages at the wound site. These events were accompanied by significant (likely compensatory) changes in the expression of genes involved in tissue patterning, including up-regulation of FKBP5 6 hours post DEX exposure and that of Wnt3a and RARγ at 24 hours post amputation. Taken together, this study provides evidence that DEX exposure during early sensitive periods of development appears to cause permanent alterations in the cellular/molecular immune processes that are involved in the early phase of wound healing in zebrafish. These findings are consistent with previous studies showing that antenatal course of DEX is associated with immediate and lasting alterations of the immune system in rodent models and humans. Therefore, the current findings support the use of the larval zebrafish model to study the impact of stress and stress hormone exposure in immature organisms on health risks in later life. © 2015 by the Wound Healing Society.

The fee exemption policy for EmONC in Mali aims to lower the financial barrier to care. The objective of the study was to evaluate the direct and indirect expenses associated with caesarean interventions performed in EmONC and the factors associated with these expenses. Data sampling followed the case control approach used in the large project (deceased and near-miss women). Our sample consisted of a total of 190 women who underwent caesarean interventions. Data were collected from the health workers and with a social approach by administering questionnaires to the persons who accompanied the woman. Household socioeconomic status was assessed using a wealth index constructed with a principal component analysis. The factors significantly associated with expenses were determined using multivariate linear regression analyses. Women in the Kayes region spent on average 77,017 FCFA (163 USD) for a caesarean episode in EmONC, of which 70 % was for treatment. Despite the caesarean fee exemption, 91 % of the women still paid for their treatment. The largest treatment-related direct expenses were for prescriptions, transfusion, antibiotics, and antihypertensive medication. Near-misses, women who presented a hemorrhage or an infection, and/or women living in rural areas spent significantly more than the others. Although abolishing fees of EmONC in Mali plays an important role in reducing maternal death by increasing access to caesarean sections, this paper shows that the fee policy did not benefit to all women. There are still barriers to EmONC access for women of the lowest socio-economic group. These included direct expenses for drugs prescription, treatment and indirect expenses for transport and food.

Vaginal Birth After Caesarean Section in Low Resource Settings: The Clinical and Ethical Dilemma.

PubMed

Wanyonyi, Sikolia; Muriithi, Francis G

2015-10-01

Vaginal birth after Caesarean section (VBAC) has long been practised in low resource settings using unconventional methods. This not only poses danger to the woman and her baby, but could also have serious legal and ethical implications. The adoption of this practice has been informed by observational studies with many deficiencies; this is so despite other studies from settings in which the standard of care is much better that show that elective repeat Caesarean section (ERCS) may actually be safer than VBAC. This raises questions about whether we should insist on a dangerous practice when there are safer alternatives. We highlight some of the challenges faced in making this decision, and discuss why the fear of ERCS may not be justified after all in low resource settings. Since a reduction in rates of Caesarean section may not be applicable in these regions, because their rates are already low, the emphasis should instead be on adequate birth spacing and safer primary operative delivery.

We assessed the effect of warming intravenous fluids during elective caesarean section under combined spinal-epidural anaesthesia in a blinded, randomised controlled trial. Seventy-five women having elective caesarean section were randomly assigned to receive all intravenous fluids at room temperature, or heated in a cabinet set at 45 degrees C or via a Hotline fluid warmer (Smiths Medical International Ltd, Watford, Herts, UK). After 10 mL/kg crystalloid preload, combined spinal-epidural anaesthesia was performed. Core and ambient temperatures, thermal comfort and shivering were measured every 15 min thereafter. The primary outcome was the temperature at 60 min. Temperature decreased in all groups. Although the temperature decrease at 60 min was similar in the heated cabinet and Hotline groups, the room temperature group exhibited a greater decrease [difference 0.4 degrees C (95% CI 0.2-0.6 degrees C); P=0.015]. More women felt cold in the room temperature group (8: 32%) than in the heated cabinet set (3: 12%) and Hotline (1: 4%) groups (P=0.02), but the incidence of shivering was similar: 11 (44%), 9 (36%) and 7 (28%) respectively. Apgar scores and neonatal cord gases were similar. Warming intravenous fluids mitigates the decrease in maternal temperature during elective caesarean section under combined spinal-epidural anaesthesia and improves thermal comfort, but does not affect shivering. Intravenous fluids should be warmed routinely in elective caesarean section, especially for cases of expected long duration, but the use of pre-warmed fluids is as efficient and cheaper than using a Hotline fluid warmer.

caesarean section plays an important role in ensuring safety of mother and infant but rising rates are not accompanied by measurable improvements in maternal or neonatal mortality or morbidity. The 'Focus on Normal Birth and Reducing Caesarean section Rates Rapid Improvement Programme' was a facilitative initiative developed to promote opportunities for normal birth and reduce caesarean section rates in England. to evaluate the 'Focus on Normal Birth and Reducing Caesarean section Rates' programme, by assessment of: impact on caesarean section rates, use of service improvements tools and participants׳ perceptions of factors that sustain or hinder work within participating maternity units. a mixed methods approach included analysis of mode of birth data, web-based questionnaires and in-depth semi-structured telephone interviews. twenty Hospital Trusts in England (selected from 68 who applied) took part in the 'Focus on Normal Birth and Reducing Caesarean section Rates Rapid Improvement Programme' initiative. In each hospital Trust, the head of midwifery, an obstetrician, the relevant lead for organisational development, a supervisor of midwives, or a clinical midwife and a service user representative were invited to participate in the independent evaluation. collection and analysis of mode of birth data from 20 participating hospital Trusts, web-based questionnaires administered to key individuals in all 20 Trusts and in-depth semi-structured telephone interviews conducted with key individuals in a sample of six Trusts. there was a marginal decline of 0.5% (25.9% from 26.4%) in mean total caesarean section rate in the period 1 January 2009 to 31 January 2010 compared to the baseline period (1 July-31 December 2008). Reduced total caesarean section rates were achieved in eight trusts, all with higher rates at the beginning of the initiative. Features associated with lower caesarean section rates included a shared philosophy prioritising normal birth, clear

This research established the scientific bases for the folkloric use of the neglected Dialium guineense fruit coat in wound and microbial infection management in Nigeria. The phytochemical analysis of the crude extract, fractions and sub-fractions was performed by standard methods. Agar well diffusion protocol was adopted for the antimicrobial assay while the wound healing properties was determined by full thickness skin excision wound model. Phytochemical analysis showed high relative proportion of alkaloids (6.05 ± 0.98 %), saponins (3.91 ± 0.02 %) and tannins (1.86 ± 0.05 %). The only active fraction (DF) and sub-fraction (DF-5) were effective against Gram-positive (inhibition zone diameters, IZDs, 8-10 mm and 11-15 mm) and Gram-negative (IZDs, 15-19 mm and 16-21 mm) bacteria and fungi (6-8 mm) compared with 20-24 mm and 18-19 mm of the standard (ciprofloxacin) respectively. Fifty mg/kg of the DF-5 showed nearly equal percentage wound healing post-surgery days to Cicatrin®. The 50 mg/kg dose of DF and DF-5 showed more than 50 % wound healing at 10(th) day post-surgery, 50 mg/kg crude extract showed 54 % on day 14 while distilled water showed 56 % wound healing on day 17 with no sign of infection in all animal groups. All the treatments were significantly (P<0.01) different from control (distilled water) in wound healing by the 10(th) and 17(th) post-surgery days. The studies revealed that the fruit coat, which hitherto was treated as wastes could be explored for antimicrobial and wound healing properties against the backdrop of continually emerging antibiotic resistant strains of microorganisms.

In Chilean hospitals the current model of care after caesarean section is to separate newborn infants from both parents. The care of newborn infants and the parents' experience immediately after caesarean section requires further exploration. To describe fathers' experiences and perceptions of being the primary caregiver to their newborn infant during the first 90 minutes after caesarean section in a public general maternity hospital setting in Santiago de Chile. The questionnaire was one part of a larger research programme named: "Caregiving Models after Elective Caesarean Section - Parents' perceptions and effects on infants' wellbeing". Four open ended questions were used to gather written text on the experiences and perceptions of 95 fathers who were the primary caregiver to their newborn infant. Ethical approval was obtained from the Ethics Committee, Scientific Assessment Metropolitan Health Service South East. Systematic text condensation according to Malterud's description was used for analysis of the written text. Two themes were identified: "understanding the first moment of life" and "shared responsibility for future family life" with each theme divided into six categories. This study concludes by arguing that in situations where the mother is unavailable or unable to provide basic care, the father should be supported to care for the newborn infant. Parents should be made aware of the benefits of this caring model especially when mother and baby have been separated after birth. Copyright © 2016 Elsevier B.V. All rights reserved.

To investigate the association between maternal country of birth and father's origin and unplanned and planned caesarean birth in Sweden. Population-based register study including all singleton births in Sweden between 1999 and 2012 (n = 1 311 885). Multinomial regression was conducted to estimate odds ratios (OR) for unplanned and planned caesarean with 95% confidence intervals for migrant compared with Swedish-born women. Analyses were stratified by parity. Women from Ethiopia, India, South Korea, Chile, Thailand, Iran, and Finland had statistically significantly higher odds of experiencing unplanned (primiparous OR 1.10-2.19; multiparous OR 1.13-2.02) and planned caesarean (primiparous OR 1.18-2.25; multiparous OR 1.13-2.46). Only women from Syria, the former Yugoslavia and Germany had consistently lower risk than Swedish-born mothers (unplanned: primiparous OR 0.76-0.86; multiparous OR 0.74-0.86. Planned; primiparous OR 0.75-0.82; multiparous OR 0.60-0.94). Women from Iraq and Turkey had higher odds of an unplanned caesarean but lower odds of a planned one (among multiparous). In most cases, these results remained after adjustment for available social characteristics, maternal health factors, and pregnancy complications. Both parents being foreign-born increased the odds of unplanned and planned caesarean in primiparous and multiparous women. Unplanned and planned caesarean birth varied by women's country of birth, with both higher and lower rates compared with Swedish-born women, and the father's origin was also of importance. These variations were not explained by a wide range of social, health, or pregnancy factors. © 2017 John Wiley & Sons Ltd.

Mode of delivery after one caesarean section: audit of current practice in a health region.

Paterson, C M; Saunders, N J

OBJECTIVE--To audit the subsequent obstetric management of women who had had one previous baby delivered by caesarean section. DESIGN--Retrospective analysis of a regional obstetric database. SETTING--Data derived from the 17 obstetric units in North West Thames region. SUBJECTS--1059 women who delivered a singleton fetus of at least 37 weeks' gestation with a cephalic presentation in 1988 who had a history of one previous caesarean section and no other deliveries. MAIN OUTCOME MEASURES--Mode of delivery, postnatal morbidity, and duration of hospital stay. RESULTS--395 (37%) women were delivered by elective repeat caesarean section and 664 (63%) were allowed a trial of labour. Maternal height and birth weight of the previous infant differed significantly between those who were and those who were not allowed to labour. 471 (71%) of those allowed to labour achieved a vaginal delivery. In individual units there was no significant correlation between the proportion of patients allowed to labour and the rate of the successful trial of labour. There was a trend towards greater success rates in units that allowed a longer duration of labour (p less than 0.05) and units with greater use of oxytocin for augmentation of labour (not significant). Both elective and intrapartum caesarean section was associated with a significantly higher rate of postnatal infection than vaginal delivery (14.7% and 16.0% v 3.4%). CONCLUSIONS--In patients with a history of caesarean section there is no evidence that the likelihood of successful vaginal delivery after trial of labour is modified by the proportion of such patients allowed the option of attempted vaginal delivery. Until selection criteria of adequate prognostic value can be identified a more liberal approach to allowing women a trial of labour seems justified. PMID:1932972

To investigate optimal timing of elective repeat caesarean section among low-risk pregnant women with prior caesarean section in a multicountry sample from largely low- and middle-income countries. Secondary analysis of a cross-sectional study. Twenty-nine countries from the World Health Organization Multicountry Survey on Maternal and Newborn Health. 29,647 women with prior caesarean section and no pregnancy complications in their current pregnancy who delivered a term singleton (live birth and stillbirth) at gestational age 37-41 weeks by pre-labour caesarean section, intra-partum caesarean section, or vaginal birth following spontaneous onset of labour. We compared the rate of short-term adverse maternal and newborn outcomes following pre-labour caesarean section at a given gestational age, to those following ongoing pregnancies beyond that gestational age. Severe maternal outcomes, neonatal morbidity, and intra-hospital early neonatal mortality. Odds of neonatal morbidity and intra-hospital early neonatal mortality were 0.48 (95% confidence interval [CI] 0.39-0.60) and 0.31 (95% CI 0.16-0.58) times lower for ongoing pregnancies compared to pre-labour caesarean section at 37 weeks. We did not find any significant change in the risk of severe maternal outcomes between pre-labour caesarean section at a given gestational age and ongoing pregnancies beyond that gestational age. Elective repeat caesarean section at 37 weeks had higher risk of neonatal morbidity and mortality compared to ongoing pregnancy, however risks at later gestational ages did not differ between groups.

Wound healing in orthopaedic care is affected by the causes of the wound, as well as concomitant therapies used to repair musculoskeletal structures. Promoting the health of the host and creating an environment to foster natural healing processes is essential for helping to restore skin integrity. Normal wound healing physiologic processes, factors affecting wound healing, wound classification systems, unique characteristics of orthopaedic wounds, wound contamination and drainage characteristics, and potential complications are important to understand in anticipation of patient needs. Accurate wound assessment and knowledge of nursing implications with specific wound care measures (cleansing, debridement, and dressings) is important for quality care. New technologies are enhancing traditional wound care measures with goals of effective comfortable wound care to promote restoration of skin integrity.

Children born in 1991-1992 in Avon, UK who participated in the Avon Longitudinal Study of Parents and Children (ALSPAC) (n=10 219). standardized measures of body mass (weight-for length z-scores at 6 weeks, 10 and 20 months; and body mass index (BMI) z-scores at 38 months, 7, 9, 11 and 15 years). Secondary outcome: categorical overweight or obese (BMI: 85th percentile) for age and gender, at 38 months, 7, 9, 11 and 15 years. Of the 10 219 children, 926 (9.06%) were delivered by caesarean section. Those born by caesarean had lower-birth weights than those born vaginally (-46.1 g, 95% confidence interval(CI): 14.6-77.6 g; P=0.004). In mixed multivariable models adjusting for birth weight, gender, parental body mass, family sociodemographics, gestational factors and infant feeding patterns, caesarean delivery was consistently associated with increased adiposity, starting at 6 weeks (+0.11 s.d. units, 95% CI: 0.03-0.18; P=0.005), through age 15 (BMI z-score increment+0.10 s.d. units, 95% CI: 0.001-0.198; P=0.042). By age 11 caesarean-delivered children had 1.83 times the odds of overweight or obesity (95% CI: 1.24-2.70; P=0.002). When the sample was stratified by maternal pre-pregnancy weight, the association among children born of overweight/obese mothers was strong and long-lasting. In contrast, evidence of an association among children born of normal-weight mothers was weak. Cesarean delivery is associated with increased body mass in childhood and adolescence. Research is needed to further characterize the association in children of normal weight women. Additional work is also needed to understand the mechanism underlying the association, which may involve relatively enduring changes in the intestinal microbiome.

Obstetric haemorrhage accounts for 20-25% of maternal mortality and morbidity. Anti-fibrinolytics are being widely used in field of surgery. It is also used to reduce heavy menstrual blood loss. To analyse the effectiveness of Tranexamic Acid (TXA) in reducing blood loss during elective caesarean section. This interventional, randomized, parallel group study was done in the Department of Obstetrics and Gynaecolgy, PSG IMSR, Coimbatore, from June 2014 to May 2015. It was conducted on 120 women undergoing caesarean section. They were allocated to either Study or Control group by computer generated random number tables. TXA was given prior to surgery in study group in addition to the routine care {10 units of oxytocin added to the intravenous drip soon after baby delivery} whereas, the control group had routine care alone. Blood loss was measured in both groups by gravimetric method. Haemoglobin before and after surgery was estimated and the percentage of difference was compared. Primary outcome variables were volume of blood loss and percentage fall in haemoglobin before and after surgery. Secondary outcomes were duration of surgery, proportion of subjects with >500ml of blood loss, need for additional uterotonics and side effects. Unpaired t-test and Chi-square test were used to compare the outcome variables. There was significant reduction in blood loss calculated from placental delivery till end of surgery: 347.17ml in study group versus 517.72ml in control group (p<0.001). Another parameter studied was the percentage of fall in haemoglobin before and after surgery and the number of subjects who had more than 10% fall in haemoglobin. 9.3% of subjects in study group and 39% of subjects in control group had more than 10% fall in haemoglobin (p<0.01). There were no immediate post-operative complications to the mother and neonate. TXA significantly reduced the amount of blood loss during Lower Segment Caesarean Section (LSCS). Use of TXA was not associated with

The widespread adoption of enhanced recovery programmes in various surgical specialties has resulted in patient benefits including reduced morbidity, reduced length of stay and an earlier return to normal activities. This evidence, along with the increased financial pressures in the UK National Health Service, has led many units to consider introducing such a programme for obstetric surgery. We report our experience in setting up an enhanced recovery programme for women undergoing elective caesarean section and a prospective analysis of factors that influence length of stay. An enhanced recovery pathway was designed by a multidisciplinary team and introduced in March 2012. Factors influencing length of stay were determined using a log normal model. The proportion of women discharged on Day 1 increased from 1.6% in the first quarter of 2012 to 25.2% in the first quarter of 2014. The 30-day readmission rate was 4.4% for those discharged on Day 1 and 5.6% for Day 2. Earlier gestation, multiple birth, intention to breast feed, longer surgery and more time in the post-anaesthesia recovery unit were all independently associated with a longer postoperative stay. Women presenting for obstetric surgery with the indication "one previous caesarean section" were more likely to leave hospital earlier compared to most other indications. An enhanced recovery programme was successfully introduced into our unit. Many of the interventions were straightforward and could be adopted easily elsewhere. Copyright © 2015 Elsevier Ltd.

The optimum mode of breech delivery remains a matter of controversy among obstetricians worldwide. To determine whether term breech babies born by planned vaginal delivery are at higher risk of neonatal mortality and morbidity than those born by planned caesarean delivery. A hospital based non-experimental comparison of outcome of breech delivery. Ife State Hospitals Complex, Ile-Ife. Two hundred and fourty four singleton breech deliveries occurring at term. They include low 5-minute Apgar score, birth trauma, maternal and perinatal morbidity and mortality. The perinatal mortality was not significantly different in both groups: OR 2.7 (95% C.I. 0.3-26.8). The low 5-minute Apgar scores were higher in the planned vaginal delivery OR 9.0 (95% C.I. 1-73.4), but the traumatic morbidity was not (OR 1.8, 95% C.I. 0.2-20.1). Maternal morbidity occurred more in the planned Caesarean delivery group OR 0.4 (95% C.I. 0.2-0.9). Given appropriate selection criteria and management protocol, the outcome from elective caesarean section might not be better than from planned vaginal delivery.

Background: Frog skin secretions have potentials against a wide spectrum of bacteria. Also, frog skin compositions have healing properties. Objectives: The aim of this study was to investigate the antibacterial potentials along with healing properties of frog skin Rana ridibunda, a species which thoroughly lives in Iran marshes, as a biological dressing on wounds. Materials and Methods: In this study, excisional wounds, dressed with frog skin, were compared between experimental and control groups of guinea pigs. In the experimental groups, wounds were dressed with the dermal (FS) and epidermal (RFS) sides of fresh frog R. ridibunda skin, while only usual cotton gauze covered the wounds of the control group. Furthermore, microbial samples were taken on different days (0, 3, 5, and 7 days post injury) to count the number of the colony-forming units. Additionally, the microbial penetration test was performed on frog skin and then the progression of wound closure was evaluated. Results: In the microbial studies, the bacterial load considerably declined in the wounds treated with FS and RFS compared with the control wounds. On day 7 post injury, the numbers of the colony-forming units for the FS, RFS, and control groups were 6.75, 105, and 375, respectively. In the penetration test, fresh frog skin showed to be a bacterial resistant dressing. The results revealed that the rate of wound closure in the experimental groups significantly was accelerated in comparison with that in the control group. Conclusions: Our results demonstrated the antimicrobial properties of frog skin as a wound dressing, which has antimicrobial effects per se. This biological dressing shows promise as an effective biological wound dressing insofar as not only is it capable of resisting microbes and accelerating wound healing but also it is cost-effective and easy to use.

The purpose of this study was to assess the level of air contamination with bacteria after surgical hydrodebridement and to determine the effectiveness of hydro surgery on bacterial reduction of a simulated infected wound. Four porcine samples were scored then infected with a broth culture containing a variety of organisms and incubated at 37 degrees C for 24 hours. The infected samples were then debrided with the hydro surgery tool (Versajet, Smith and Nephew, Largo, Florida, USA). Samples were taken for microbiology, histology and scanning electron microscopy pre-infection, post infection and post debridement. Air bacterial contamination was evaluated before, during and after debridement by using active and passive methods; for active sampling the SAS-Super 90 air sampler was used, for passive sampling settle plates were located at set distances around the clinic room. There was no statistically significant reduction in bacterial contamination of the porcine samples post hydrodebridement. Analysis of the passive sampling showed a significant (p < 0.001) increase in microbial counts post hydrodebridement. Levels ranging from 950 colony forming units per meter cubed (CFUs/m3) to 16780 CFUs/m3 were observed with active sampling of the air whilst using hydro surgery equipment compared with a basal count of 582 CFUs/m3. During removal of the wound dressing, a significant increase was observed relative to basal counts (p < 0.05). Microbial load of the air samples was still significantly raised 1 hour post-therapy. The results suggest a significant increase in bacterial air contamination both by active sampling and passive sampling. We believe that action might be taken to mitigate fallout in the settings in which this technique is used.

To examine the between-hospital variation of charges and discounted prices for uncomplicated vaginal and caesarean section deliveries, and to determine the institutional and market-level characteristics that influence adjusted charges. Using data from the California Office of Statewide Health Planning and Development (OSHPD), we conducted a cross-sectional study of all privately insured patients admitted to California hospitals in 2011 for uncomplicated vaginal delivery (diagnosis-related group (DRG) 775) or uncomplicated caesarean section (DRG 766). Hospital charges and discounted prices adjusted for each patient's clinical and demographic characteristics. We analysed 76 766 vaginal deliveries and 32 660 caesarean sections in California in 2011. After adjusting for patient demographic and clinical characteristics, we found that the average California woman could be charged as little as US$3296 or as much as US$37 227 for a vaginal delivery, and US$8312-US$70 908 for a caesarean section depending on which hospital she was admitted to. The discounted prices were, on an average, 37% of the charges. We found that hospitals in markets with middling competition had significantly lower adjusted charges for vaginal deliveries, while hospitals with higher wage indices and casemixes, as well as for-profit hospitals, had higher adjusted charges. Hospitals in markets with higher uninsurance rates charged significantly less for caesarean sections, while for-profit hospitals and hospitals with higher wage indices charged more. However, the institutional and market-level factors included in our models explained only 35-36% of the between-hospital variation in charges. These results indicate that charges and discounted prices for two common, relatively homogeneous diagnosis groups-uncomplicated vaginal delivery and caesarean section-vary widely between hospitals and are not well explained by observable patient or hospital characteristics.

[Prophylaxis and treatment of arterial hypotension during caesarean with spinal anaesthesia].

PubMed

Arias, J; Lacassie, H J

2013-11-01

Caesarean section is one of the most common surgical procedures worldwide. Arterial hypotension is the most prevalent adverse effect after spinal anaesthesia. Various methods have been used to prevent or treat hypotension. Since there is no treatment 100% effective by itself, a multimodal management is required to achieve an optimum balance and avoidance of hemodynamic imbalance. Strategies to avoid this side effect are analyzed on the basis of the best evidence available so far, summarized as mechanical factors, anesthetics, fluids and vasopressors. After spinal anaesthesia for caesarean section, the best strategy available for prevention of hypotension appears to be the combination of crystalloids along with an alpha 1 agonist vasopressor.

Foxn1 Transcription Factor Regulates Wound Healing of Skin through Promoting Epithelial-Mesenchymal Transition

PubMed Central

2016-01-01

Transcription factors are key molecules that finely tune gene expression in response to injury. We focused on the role of a transcription factor, Foxn1, whose expression is limited to the skin and thymus epithelium. Our previous studies showed that Foxn1 inactivity in nude mice creates a pro-regenerative environment during skin wound healing. To explore the mechanistic role of Foxn1 in the skin wound healing process, we analyzed post-injured skin tissues from Foxn1::Egfp transgenic and C57BL/6 mice with Western Blotting, qRT-PCR, immunofluorescence and flow cytometric assays. Foxn1 expression in non-injured skin localized to the epidermis and hair follicles. Post-injured skin tissues showed an intense Foxn1-eGFP signal at the wound margin and in leading epithelial tongue, where it co-localized with keratin 16, a marker of activated keratinocytes. This data support the concept that suprabasal keratinocytes, expressing Foxn1, are key cells in the process of re-epithelialization. The occurrence of an epithelial-mesenchymal transition (EMT) was confirmed by high levels of Snail1 and Mmp-9 expression as well as through co-localization of vimentin/E-cadherin-positive cells in dermis tissue at four days post-wounding. Involvement of Foxn1 in the EMT process was verified by co-localization of Foxn1-eGFP cells with Snail1 in histological sections. Flow cytometric analysis showed the increase of double positive E-cadherin/N-cadherin cells within Foxn1-eGFP population of post-wounded skin cells isolates, which corroborated histological and gene expression analyses. Together, our findings indicate that Foxn1 acts as regulator of the skin wound healing process through engagement in re-epithelization and possible involvement in scar formation due to Foxn1 activity during the EMT process.

To identify the role of bilateral internal iliac artery (IIA) ligation on reducing blood loss in abnormally invasive placenta (AIP) undergoing caesarean hysterectomy. In this parallel-randomized control trial, 57 pregnant females with ultrasound features suggestive of AIP were enrolled. They were randomized into two groups; IIA group (n = 29 cases) performed bilateral IIA ligation followed by caesarean hysterectomies, while Control group (n = 28 cases) underwent caesarean hysterectomy only. The main outcome was the difference in the estimated intraoperative blood loss between the two groups. There was no significant difference between the two groups regarding the intraoperative estimated blood loss (1632 ± 804 versus 1698 ± 1251, p value .83). The operative procedure duration (minutes) (223 ± 66 versus 171 ± 41.4, p value .001) varied significantly between the two groups. Bilateral internal iliac artery ligation, in cases of AIP undergoing caesarean hysterectomy, is not recommended for routine practice to minimize blood loss intraoperatively.

To describe the results of increasing availability and quality of caesarean deliveries and anaesthesia in rural Tanzania. Before-after intervention study design. Rural Tanzania. Ten health centres located in rural areas were upgraded to provide comprehensive emergency obstetric care (CEmOC) and the four related district hospitals were supported. Upgrading entailed constructing and equipping maternity blocks, operation rooms and laboratories; installing solar systems, backup generators and water supply systems. Associate clinicians were trained in anaesthesia and in CEmOC. Mentoring and audit of reasons for caesarean section (CS) and maternal deaths were carried out. Measures of interest were compared using analysis of variance (ANOVA) statistical tests. Trends in CS rates, proportion of unjustified CS, use of spinal anaesthesia, and the risk of death from complications related to CS and anaesthesia. During the audit period (2012-2014), 5868 of 58 751 deliveries were by CS (10%). The proportion of CS considered to be unjustified decreased from 30 to 17% in health centres (P = 0.02) and from 37 to 20% in hospitals (P < 0.001). Practice of spinal anaesthesia for CS increased from 10% to 64% in hospitals (P < 0.001). Of 110 maternal deaths, 18 (16.4%) were associated with complications of CS, giving a risk of 3.1 per 1000 CS; three (2.7%) were judged to be anaesthetic-associated deaths with a risk of 0.5 per 1000 caesarean deliveries. Increasing availability and quality of CS by improving infrastructure, training and audit of reasons for CS is feasible, acceptable and required in low resource settings. Increasing availability and quality of CS in rural Africa is feasible. © 2016 Royal College of Obstetricians and Gynaecologists.

Manual displacement of the uterus during Caesarean section.

Ninety ASA 1 and 2 pregnant women with term singleton pregnancies and no maternal and fetal complications, scheduled for elective or emergency Caesarean section, were randomly allocated to group LT (15 degrees left lateral table tilt, n = 45) and group MD (leftward manual displacement, n = 45). Subarachnoid block was established with a 25-gauge spinal needle at the L3-L4 interspace using 1.5 ml of 0.5% hyperbaric bupivacaine. A median sensory level of T6 was observed in both groups but the incidence of hypotension was markedly lower in group MD when compared to group LT (4.4% vs 40%; p < 0.001) with a significant reduction in mean (SD) ephedrine requirement (6 (0) vs 11.3 (4.9) mg; p < 0.001). The mean (SD) fall in systolic blood pressure was 28.8 (7.3) mmHg in group LT and 20 (12.7) mmHg in group MD. The time to maximum fall in systolic blood pressure was similar in both groups (4.5 min). We conclude that manual displacement of the uterus effectively reduces the incidence of hypotension and ephedrine requirements when compared to 15 degrees left lateral table tilt in parturients undergoing Caesarean section.

Nonlinear optical microscopy (NLOM) was employed for imaging and evaluating the wound healing process on rat skin in vivo. From the high-resolution nonlinear optical images, the morphology and distribution of specific biological markers in cutaneous wound healing such as fibrin clot, collagens, blood capillaries, and hairs were clearly observed at 1, 5 and 14 days post injury. We found that the disordered collagen in the fibrin clot at day 1 was replaced by regenerative collagen at day 5. By day 14, the thick collagen with well-network appeared at the original margin of the wound. These findings suggested that NLOM is ideal for noninvasively monitoring the progress of wound healing in vivo.

To evaluate caesarean section (CS) rates and moderate to severe hypoxaemic ischaemic encephalopathy (HIE) rates with other core intra-partum outcomes following reconfiguration of maternity services in Cardiff, South Wales, UK. Cohort study of births from 2006 to 2015. A University tertiary referral centre for foetal and maternal medicine with 6000 births/year, University Hospital of Wales, United Kingdom. Data relating to births from 1 January 2006 to 31 December 2015 were extracted from the computerized maternity database on a yearly basis. Case notes of all mothers and babies for the same duration were hand searched for documentation of HIE. HIE data was also collected prospectively by neonatologist (SC) and obstetrician (PA). Incidence of caesarean section births, babies with moderate to severe HIE, instrumental vaginal births, obstetric anal sphincter injuries (OASIS) associated with instrumental delivery, and major post-partum haemorrhage (MPPH) of 2500 mL or more. During this 10-year period, a downward trend in emergency CS rate was seen from 15.6% in 2006 to 10.5% in 2015, reducing total CS rate from 25.5% in 2006 to 21.2% in 2015. A downward trend in the incidence of moderate and severe HIE was seen over the same period. There was an increase in operative vaginal births (OVB) from 12.8% to 15%. The rate of spontaneous vaginal births (SVB) remained stable. The incidence of OASIS remained constant and MPPH rate has fallen. Following amalgamation of two medium sized obstetric units and the opening of a Midwifery Led Unit (MLU), core intrapartum outcomes have improved. Contributing factors are the introduction of regular multidisciplinary training with enhanced team working, compulsory education for obstetricians and midwives on cardiotocograph (CTG) interpretation, increased consultant presence on delivery suite, robust risk management systems and broad multidisciplinary agreement on clinical guidelines promoting vaginal birth.

Caesarean scar defect (CSD) can cause postmenstrual bleeding. Defect repair is an effective technique to improve this symptom, but there are still a few patients getting little improvement. This retrospective study evaluates the efficacy of scar repair and explores the factors associated with poor effect. In total, 123 patients were involved in the final analysis. All of them complained about menstruation period >7 days due to postmenstrual bleeding. Before surgery, 87.8% of patients had a menstruation period more than 10 days and 20.3% had a period more than 15 days. After surgery, a normal menstruation period (< =7 days) was achieved in 46.3% (95%CI 37.3%-55.6%) of patients and a menstruation period lasting no more than 10 days was achieved in 74.8% (95%CI 66.2%-82.2%). Through multivariate logistic analysis, four factors were found dependently associated with poor effect (defined as menstruation period >10 days after surgery): repeated caesarean section (OR 9.75, 95%CI 2.30-41.36, 0.002) was a risk factor, while defect volume >600 mm 3 (OR 0.14, 95%CI 0.03-0.56, 0.006), interval from caesarean section to symptom emerging >3 months (OR 0.25, 95%CI 0.07-0.94, 0.041) and straight or retroflexed uterus (OR 0.19, 95%CI 0.05-0.79, 0.022) were protective factors. Impact statement What is already known on this subject? Caesarean scar defect can cause postmenstrual bleeding. Defect repair can improve this symptom, but there are still a few patients getting little improvement after surgery. What do the results of this study add? Defect volume >600 mm 3 , interval from caesarean section to symptom emerging >3 months and straight or retroflexed uterus are protective factors of poor effect (defined as menstruation period >10 days after surgery), and repeated caesarean section is a risk factor. What are the implications of these findings for clinical practice and/or further research? These findings may help in counselling the patients and in medical

Caesarean section (CS) rates are known to vary by country, migration status and social group. However, little population-based, confounder adjusted evidence exists on caesarean rate for African immigrants in Australia. To investigate disparities in first-time caesarean, mainly unplanned caesarean in labour for women born in Eritrea, Ethiopia, Somalia and Sudan relative to Australian-born women in public care. A population-based study of 237 943 Australian and 4057 Eastern African singleton births between 1999 and 2007, was conducted using Victorian Perinatal Data Collection. Descriptive and multivariable logistic regression analysis by parity, adjusting for confounders selected a priori, was performed for first-time unplanned caesarean in labour and overall caesarean. Primiparae born in each of the Eastern African countries had elevated odds of unplanned caesarean in labour: Eritrea adjusted odds ratio (OR adj ) 2.04 95% CI (1.41, 2.97), Ethiopia OR adj 2.08 95% CI (1.62, 2.68), Somalia OR adj 1.62 95% CI (1.25, 2.10) and Sudan OR adj 1.39 95% CI (1.03, 1.87). Similarly, multiparae from Eastern African countries had elevated odds of unplanned caesarean in labour: Eritrea OR adj 2.13 95%CI(1.15, 3.97), Ethiopia OR adj 2.05 95% CI (1.38, 3.03), Somalia OR adj 2.16 95% CI (1.69, 2.77) and Sudan OR adj 1.81 95% CI (1.32, 2.49). The odds of any first-time caesarean (planned or unplanned) were elevated for primiparae born in all countries except Sudan and for multiparae born in Ethiopia and Somalia. We observed substantial variations in a first-time CS between Eastern African and Australian-born women in Victoria, Australia. However, these disparities were unexplained by socio-demographic and clinical risks, suggesting the potential importance of other factors such as communication difficulties, support systems for immigrant pregnant women and possible differences in care. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Honey as a topical treatment for wounds.

PubMed

Jull, Andrew B; Rodgers, Anthony; Walker, Natalie

2008-10-08

Honey is a viscous, supersaturated sugar solution derived from nectar gathered and modified by the honeybee, Apis mellifera. Honey has been used since ancient times as a remedy in wound care. Evidence from animal studies and some trials has suggested honey may accelerate wound healing. The objective was to determine whether honey increases the rate of healing in acute wounds (burns, lacerations and other traumatic wounds) and chronic wounds (venous ulcers, arterial ulcers, diabetic ulcers, pressure ulcers, infected surgical wounds). We searched the Cochrane Wounds Group Specialised Register (May 2008), CENTRAL (May 2008) and several other electronic databases (May 2008). Bibliographies were searched and manufacturers of dressing products were contacted for unpublished trials. Randomised and quasi randomised trials that evaluated honey as a treatment for any sort of acute or chronic wound were sought. There was no restriction in terms of source, date of publication or language. Wound healing was the primary endpoint. Data from eligible trials were extracted and summarised using a data extraction sheet by one author and independently verified by a second author. 19 trials (n=2554) were identified that met the inclusion criteria. In acute wounds, three trials evaluated the effect of honey in acute lacerations, abrasions or minor surgical wounds and nine trials evaluated the effect the honey in burns. In chronic wounds two trials evaluated the effect of honey in venous leg ulcers and one trial in pressure ulcers, infected post-operative wounds, and Fournier's gangrene respectively. Two trials recruited people with mixed groups of chronic or acute wounds. The poor quality of most of the trial reports means the results should be interpreted with caution, except in venous leg ulcers. In acute wounds, honey may reduce time to healing compared with some conventional dressings in partial thickness burns (WMD -4.68 days, 95%CI -4.28 to -5.09 days). All the included burns

VAGINAL BIRTH AFTER A PREVIOUS CAESAREAN SECTION: CURRENT TRENDS AND OUTLOOK IN GHANA.

The optimal mode of subsequent delivery of women with prior caesarean birth remains a subject of intense research and debate in contemporary obstetric practice especially in low resource settings like West Africa where there are obvious systemic and management-related challenges associated with trial of scar. However, there is evidence that vaginal birth after caesarean section (VBAC) is safe in appropriately selected women in addition to adequate intrapartum monitoring and ready access to theatre when emergency CS is indicated. The primary objective of the study was to determine the current trends and performance of VBAC in Ghana after decades of practice of trial of labour after caesarean section (TOLAC) in the mist of inherent challenges in deciding the optimal mode of childbirth for women with a previous caesarean birth. The secondary objective was to relate evidence based practice of TOLAC to obstetric practice in low resource settings like Ghana and provide recommendations for improving maternal and newborn health among women with prior caesarean birth. This was a retrospective study of the records of patients who had had a prior caesarean delivery and who then proceeded to deliver the next babies at the Korle Bu Teaching Hospital (KBTH) between Jan 2010 and Dec 2014. The data on demography, antenatal care, labour and delivery and outcomes were collected from the Labour and Recovery wards and the Biostatistics unit of the Maternity unit of the Hospital. Excluded were women with a previous CS who had multiple pregnancies and those with incomplete notes as well as those whose delivery plans were not predetermined antenatally.. The data were analyzed using SPSS version 20. There were 53,581 deliveries during the study period. Vaginal delivery was obtained in 31,870 (59.5%) pregnancies and 21,711(40.5%) had CS. Also, 6261 (11.7%) had had a prior CS and 2472 (39.5%) of these were selected for TOLAC while 2119 (33.8) were scheduled for planned repeat CS. There was

Negative pressure wound therapy in orthopaedic surgery.

PubMed

Robert, N

2017-02-01

Negative pressure wound therapy (NPWT) consists in applying subatmospheric pressure to a wound that is sealed off by a specially designed dressing and connected by a tube to a suction pump and drainage collection system. Skin defects are extremely common in orthopaedic and trauma surgery. NPWT is valuable across a range of indications. Proven effects include an increase in blood flow, stimulation of angiogenesis, and a decrease in wound surface area. NPWT can be used to treat post-traumatic and surgical wounds, burns, and chronic wounds such as pressure sores and ulcers. The lower frequency of dressing changes with NPWT lightens the staff workload. The French high authority for health (HAS) has issued good practice guidelines for the use of NPWT in specific and limited indications. NPWT has benefited from the introduction of several technological improvements such as silicone interfaces, foam dressings with various densities and pore sizes, and irrigation systems. The result is greater adaptability to each specific situation. Nevertheless, NPWT is not appropriate in every case and cannot replace a necessary surgical procedure. The goal of this work is to review the principles, practical modalities, and indications of NPWT. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

2017-05-01

The objective of this study was to assess effectiveness and safety of the reverse breech extraction approach in Caesarean section for obstructed labour, and compare it with the standard approach of pushing the fetal head up through the vagina. This randomised controlled trial included 192 women. In 96, the baby was delivered by the 'reverse breech extraction approach', and in the remaining 96, by the 'standard approach'. Extension of uterine incision occurred in 18 participants (18.8%) in the reverse breech extraction approach group, and 46 (47.9%) in the standard approach group (p = .0003). Two women (2.1%) in the reverse breech extraction approach group needed blood transfusion and 11 (11.5%) in the standard approach group (p = .012). Pyrexia developed in 3 participants (3.1%) in the reverse breech extraction approach group, and 19 (19.8%) in the standard approach group (p = .0006). Wound infection occurred in 2 women (2.1%) in the reverse breech extraction approach group, and 12 (12.5%) in the standard approach group (p = .007). Apgar score <7 at 5 minutes was noted in 8 babies (8.3%) in the reverse breech extraction approach group, and 21 (21.9%) in the standard approach group (p = .015). In conclusion, reverse breech extraction in Caesarean section for obstructed labour is an effective and safe alternative to the standard approach of pushing the fetal head up through the vagina.

Chronic wounds represent a significant health problem, especially in diabetic patients. In the current study, we investigated a novel therapeutic approach to wound healing – whole body low-intensity vibration (LIV). LIV is anabolic for bone, by stimulating the release of growth factors, and modulating stem cell proliferation and differentiation. We hypothesized that LIV improves the delayed wound healing in diabetic mice by promoting a pro-healing wound environment. Diabetic db/db mice received excisional cutaneous wounds and were subjected to LIV (0.4 g at 45 Hz) for 30 min/d or a non-vibrated sham treatment (controls). Wound tissue was collected at 7 and 15 d post-wounding and wound healing, angiogenesis, growth factor levels and wound cell phenotypes were assessed. LIV increased angiogenesis and granulation tissue formation at day 7, and accelerated wound closure and re-epithelialization over days 7 and 15. LIV also reduced neutrophil accumulation and increased macrophage accumulation. In addition, LIV increased expression of pro-healing growth factors and chemokines (insulin-like growth factor-1, vascular endothelial growth factor and monocyte chemotactic protein-1) in wounds. Despite no evidence of a change in the phenotype of CD11b+ macrophages in wounds, LIV resulted in trends towards a less inflammatory phenotype in the CD11b− cells. Our findings indicate that LIV may exert beneficial effects on wound healing by enhancing angiogenesis and granulation tissue formation, and these changes are associated with increases in pro-angiogenic growth factors.

A clinical trial was conducted at the National Rehabilitation Hospital on 15 individuals to assess whether Rheparan Skin, a bio-engineered component of the extracellular matrix of the skin, is effective at promoting healing of a variety of wounds. Along with standard clinical outcome measures, a spectroscopic camera was used to assess the efficacy of Rheparan skin. Gauzes soaked with Rheparan skin were placed on volunteers wounds for 5 minutes twice weekly for four weeks. Images of the wounds were taken using a multi spectral camera and a digital camera at baseline and weekly thereafter. Spectral images collected at different wavelengths were used combined with optical skin models to quantify parameters of interest such as oxygen saturation (SO2), water content, and melanin concentration. A digital wound measurement system (VERG) was also used to measure the size of the wound. 9 of the 15 measured subjects showed a definitive improvement post treatment in the form of a decrease in wound area. 7 of these 9 individuals also showed an increase in oxygen saturation in the ulcerated area during the trial. A similar trend was seen in other metrics. Spectral imaging of skin wound can be a valuable tool to establish wound-healing trends and to clarify healing mechanisms.

We explored the perceptions of 39 Somali women and 62 obstetric care providers in London in relation to caesarean birth, as borne out of a paradox we recognised from evidence-based information about the Somali group. Socio-cultural factors potentially leading to adverse obstetric outcome were identified using in-depth and focus group interviews with semi-structured, open-ended questions. A cultural anthropology model, the emic/etic model, was used for analysis. Somali women expressed fear and anxiety throughout the pregnancy and identified strategies to avoid caesarean section (CS). There was widespread, yet anecdotal, awareness among obstetric care providers about negative Somali attitudes. Caesarean avoidance and refusal were expressed as being highly stressful among providers, but also as being the responsibility of the women and families. For women, avoiding or refusing caesarean was based on a rational choice to avoid death and coping with adverse outcome relied on fatalistic attitudes. Motivation for the development of preventive actions among both groups was not described, which lends weight to the vast distinction and lack of correspondence in identified perspectives between Somali women and UK obstetric providers. Early booking and identification of women likely to avoid caesarean is proposed, as is the development of preventive strategies to address CS avoidance.

Competent patients have the right to refuse treatment and healthcare workers should acknowledge their wishes. In the Netherlands there are conflicting (constitutional) rights of the foetus and of mentally ill patients. This paper describes the legal and ethical problems in the case of a mentally ill patient at 37 weeks of pregnancy who refused an obstetric examination. The patient refused to cooperate and have her physical condition and mental status examined. Her refusal endangered the life of the foetus. The obstetrician decided to perform a caesarean section, even if this would be in conflict with the patient's right to self-determination. In these cases no legal framework exists for providing the best medical care. New legislation should be drawn up to prevent similar cases occurring in the future. If a caesarean section is in conflict with a patient's right to self-determination, it should always be performed as a last resort.

Wound Healing Is Defective in Mice Lacking Tetraspanin CD151

2010-01-01

The tetraspanin CD151 forms complexes in epithelial cell membranes with laminin-binding integrins α6 β4, α3 β1, and α6 β1, and modifies integrin-mediated cell migration in vitro. We demonstrate in this study that CD151 expression is upregulated in a distinct temporal and spatial pattern during wound healing, particularly in the migrating epidermal tongue at the wound edge, suggesting a role for CD151 in keratinocyte migration. We show that healing is significantly impaired in CD151-null mice, with wounds gaping wider at 7 days post-injury. The rate of re-epithelialization of the CD151-null wounds is adversely affected, with significantly less wound area being covered by migrating epidermal cells. Our studies reveal that although laminin levels are similar in wild-type and CD151-null wounds, the organization of the laminin in the basement membrane is impaired. Furthermore, upregulation of α6 and β4 integrin expression is adversely affected in CD151-null mice wounds. In contrast, we find no significant effect of CD151 gene knockout on α3 and β1 integrin expression in wound repair. We suggest that mice lacking the CD151 gene are defective in wound healing, primarily owing to impairment of the re-epithelialization process. This may be due to defective basement membrane formation and epithelial cell adhesion and migration. PMID:16410781

Objective The present study is designed to understand the contribution of peripheral vascular disease and peripheral neuropathy to the wound-healing impairment associated with diabetes. Using a rabbit model of diabetic neuroischemic wound-healing we investigated rate of healing, leukocyte infiltration and expression of cytokines, Interleukin (IL)-8 and IL-6, and, neuropeptides, Substance P (SP) and Neuropeptide Y (NPY). Design of study Diabetes was induced in White New Zealand rabbits by administering alloxan while control rabbits received saline. Ten days later animals in both groups underwent surgery. One ear served as a sham and the other was made ischemic (ligation of central+rostral arteries), or neuroischemic (ischemia+ resection of central+rostral nerves). Four, 6mm punch biopsy wounds were created in both ears and wound-healing was followed for ten days using computerized planimetry. Results Non-diabetic sham and ischemic wounds healed significantly more rapidly than diabetic sham and ischemic wounds. Healing was slowest in neuroischemic wounds, irrespective of diabetic status. A high M1/M2 macrophage ratio and a high pro-inflammatory cytokine expression, both indicators of chronic-proinflammatory state, and low neuropeptide expression were seen in pre-injury diabetic skin. Post-injury, in diabetic wounds M1/M2 ratio remained high, the reactive increase in cytokine expression was low and neuropeptide expression was further decreased in neuroischemic wounds. Conclusion This rabbit model illustrates how a combination of a high M1/M2 ratio, a failure to mount post-injury cytokine response as well as a diminished neuropeptide expression contribute to wound-healing impairment in diabetes. The addition of neuropathy to ischemia leads to equivalently severe impaired wound-healing irrespective of diabetes status, suggesting that in the presence of ischemia, loss of neuropeptide function contributes to the impaired healing associated with diabetes.

To examine trends in the utilisation of facility-based delivery care and caesareans in Morocco between 1987 and 2012, particularly among the poor, and to assess whether uptake increased at the time of introduction of policies or programmes aimed at improving access to intrapartum care. Using data from nationally representative household surveys and routine statistics, our analysis focused on whether women delivered within a facility, and whether the delivery was by caesarean; analyses were stratified by relative wealth quintile and public/private sector where possible. A segmented Poisson regression model was used to assess whether trends changed at key events. Uptake of facility-based deliveries and caesareans in Morocco has risen considerably over the past two decades, particularly among the poor. The rate of increase in facility deliveries was much faster in the poorest quintile (annual increase RR: 1.09; 95% CI: 1.07-1.11) than the richest quintile (annual increase RR: 1.01; 95% CI: 1.02-1.02). A similar pattern was observed for caesareans (annual increase among poorest RR: 1.13; 95% CI: 1.07-1.19 vs. annual increase among richest RR: 1.08; 95% CI: 1.06-1.10). We found no significant acceleration in trend coinciding with any of the events investigated. Morocco's success in improving uptake of facility deliveries and caesareans is likely to be the result of the synergistic effects of comprehensive demand and supply-side strategies, including a major investment in human resources and free delivery care. Equity still needs to be improved; however, the overall trend is positive. © 2015 John Wiley & Sons Ltd.

Wound management makes up an important part of the emergency physician's practice. Understanding the physiology of wound healing and the patient and wound factors affecting this process is essential for the proper treatment of wounds. There are many options available for wound closure. Each modality has its benefits and its drawbacks, and some are appropriate only for certain types of wounds. The goal is to achieve the best functional and cosmetically appealing scar while avoiding complications.

Magnesium sulphate has beneficial effects as an adjuvant during general anaesthesia for Caesarean section.

The use of low concentrations of volatile anaesthetics with avoidance of opioids may induce intraoperative awareness and adverse haemodynamic responses during Caesarean section. Magnesium is well known to reduce anaesthetic requirements and to block noxious stimuli. We investigated whether i.v. magnesium sulphate modulates anaesthetic depth and analgesic efficacy during Caesarean section. Seventy-two patients undergoing Caesarean section were randomly assigned to receive i.v. saline (control group) or magnesium sulphate 30 mg kg(-1) bolus+10 mg kg(-1) h(-1) continuous infusion (Mg 30 group) or 45 mg kg(-1) bolus+15 mg kg(-1) h(-1) continuous infusion (Mg 45 group) after induction. Bispectral index (BIS) value, mean arterial pressure (MAP), and midazolam, fentanyl, and atracurium consumptions were recorded. BIS values [mean (sd)] at 7.5 and 10 min after surgery and before delivery in the control [64 (9), 66 (8), 67 (8), P<0.001] and the Mg 30 groups [62 (8), P<0.01; 64 (7), 63 (9), P<0.001] were higher than in the Mg 45 group [56 (8), 55 (8), 55 (7)]. MAP was greater in the control group (P<0.05) than in the Mg 30 and Mg 45 groups during the pre-delivery period. The magnesium groups required less midazolam (P<0.05), fentanyl (Mg 30, P<0.05; Mg 45, P<0.01), and atracurium (P<0.001) vs the control group. Preoperative i.v. magnesium sulphate attenuated BIS and arterial pressure increases during the pre-delivery period. Magnesium sulphate can be recommended as an adjuvant during general anaesthesia for Caesarean section to avoid perioperative awareness and pressor response resulting from inadequate anaesthesia, analgesia, or both.

Objective: To explore the influence of different inner dressings in negative-pressure wound therapy (NPWT) on escharectomy wound of full-thickness burn rabbits. Methods: Eighteen Japanese white rabbits were inflicted with full-thickness burn on unilateral back. They were divided into polymer dressing group (PD), biological dressing group (BD), and silver biological dressing group (SBD), according to the random number table, with 6 rabbits in each group. On 3 days post burn, the wounds were performed with escharectomy, and then wounds of rabbits in group PD were covered with polyurethane foam. Wounds of rabbits in group BD were covered with porcine acellular dermal matrix (ADM) and wounds of rabbits in group SBD were covered with silver porcine ADM. Then continuous NPWT was performed on rabbits of the three groups for 7 days. Immediately after surgery and on post surgery day (PSD) 7, general observation of wound was conducted and tissue around the wound was harvested for determination of dry to wet weight ratio. The content of bacteria was counted and the content of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-6 in wound was determined by enzyme-linked immunosorbent assay. Fibroblasts in wound were counted after Masson staining and number of microvessels was counted after CD31 antibody immunohistochemical staining. Data were processed with analysis of variance for repeated measurement, LSD- t test, paired samples t test, and Bonferroni correction. Results: (1) Immediately after surgery, there was no granulation tissue in basal wound of rabbits in the three groups, with rich blood supply and obvious edema. On PSD 7, much granulation tissue was found in basal wound of rabbits in the three groups, with no or mild edema and no obvious redness and swelling in wound edge. (2) There were no significant differences in dry to wet weight ratios of tissue around the wound among and within the three groups immediately after surgery and on PSD 7 (with F

To assess the differences in rates and odds for emergency caesarean section among singleton pregnancies in six governmental Palestinian hospitals. A prospective population-based birth cohort study. Obstetric departments in six governmental Palestinian hospitals. 32 321 women scheduled to deliver vaginally from 1 March 2015 until 29 February 2016. To assess differences in sociodemographic and antenatal obstetric characteristics by hospital, χ 2 test, analysis of variance and Kruskal-Wallis test were applied. Logistic regression was used to estimate differences in odds for emergency caesarean section, and ORs with 95% CIs were assessed. The primary outcome was the adjusted ORs of emergency caesarean section among singleton pregnancies for five Palestinian hospitals as compared with the reference (Hospital 1). The prevalence of emergency caesarean section varied across hospitals, ranging from 5.8% to 22.6% among primiparous women and between 4.8% and 13.1% among parous women. Compared with the reference hospital, the ORs for emergency caesarean section were increased in all other hospitals, crude ORs ranging from 1.95 (95% CI 1.42 to 2.67) to 4.75 (95% CI 3.49 to 6.46) among primiparous women. For parous women, these differences were less pronounced, crude ORs ranging from 1.37 (95% CI 1.13 to 1.67) to 2.99 (95% CI 2.44 to 3.65). After adjustment for potential confounders, the ORs were reduced but still statistically significant, except for one hospital among parous women. Substantial differences in odds for emergency caesarean section between the six Palestinian governmental hospitals were observed. These could not be explained by the studied sociodemographic or antenatal obstetric characteristics. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Honey is a viscous, supersaturated sugar solution derived from nectar gathered and modified by the honeybee, Apis mellifera. Honey has been used since ancient times as a remedy in wound care. Evidence from animal studies and some trials has suggested that honey may accelerate wound healing. The objective of this review was to assess the effects of honey compared with alternative wound dressings and topical treatments on the of healing of acute (e.g. burns, lacerations) and/or chronic (e.g. venous ulcers) wounds. For this update of the review we searched the Cochrane Wounds Group Specialised Register (searched 15 October 2014); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 9); Ovid MEDLINE (1946 to October Week 1 2014); Ovid MEDLINE (In-Process & Other Non-Indexed Citations 13 October 2014); Ovid EMBASE (1974 to 13 October 2014); and EBSCO CINAHL (1982 to 15 October 2014). Randomised and quasi-randomised trials that evaluated honey as a treatment for any sort of acute or chronic wound were sought. There was no restriction in terms of source, date of publication or language. Wound healing was the primary endpoint. Data from eligible trials were extracted and summarised by one review author, using a data extraction sheet, and independently verified by a second review author. All data have been subsequently checked by two more authors. We identified 26 eligible trials (total of 3011 participants). Three trials evaluated the effects of honey in minor acute wounds, 11 trials evaluated honey in burns, 10 trials recruited people with different chronic wounds including two in people with venous leg ulcers, two trials in people with diabetic foot ulcers and single trials in infected post-operative wounds, pressure injuries, cutaneous Leishmaniasis and Fournier's gangrene. Two trials recruited a mixed population of people with acute and chronic wounds. The quality of the evidence varied between different comparisons and

Diabetic foot ulcer is closely associated with peripheral vascular disease. Enhancement of tissue oxidative stress, reduction of nitric oxide (NO) and angiogenic growth factors, and abnormal matrix metalloproteinase (MMP) activity are pathophysiological factors in post-ischemic neovascularization and diabetic wound healing. Our previous study demonstrated that the Chinese 2-herb formula, NF3, showed significant wound healing effects on diabetic foot ulcer rats. A novel rat diabetic foot ulcer with hindlimb ischemia model was established in order to strengthen our claims on the diabetic wound healing and post-ischemic neovascularization effects of NF3. Our results demonstrate that NF3 can significantly reduce the wound area of the diabetic foot ulcer rat with hindlimb ischemia by 21.6% (p<0.05) compared with the control group. In addition, flow cytometric analysis revealed that NF3 could boost circulating EPC levels for local wound vessel incorporation. Immunohistochemical analysis showed that NF3 could significantly augment blood vessel density, VEGF and eNOS expression, and attenuate tissue oxidative stress of ischemic muscles (p<0.001). NF3 significantly stimulated MMP activity involved in angiogenesis. Our study shows, for the first time, the beneficial effects of NF3 in wound healing and post-ischemic neovascularization in diabetes. Copyright © 2014 Elsevier Inc. All rights reserved.

Objectives To investigate why some women prefer caesarean sections and how decisions to medicalise birthing are influenced by patients, doctors, and the sociomedical environment. Design Population based birth cohort study, using ethnographic and epidemiological methods. Setting Epidemiological study: women living in the urban area of Pelotas, Brazil who gave birth in hospital during the study. Ethnographic study: subsample of 80 women selected at random from the birth cohort. Nineteen medical staff were interviewed. Participants 5304 women who gave birth in any of the city's hospitals in 1993. Main outcome measures Birth by caesarean section or vaginal delivery. Results In both samples women from families with higher incomes and higher levels of education had caesarean sections more often than other women. Many lower to middle class women sought caesarean sections to avoid what they considered poor quality care and medical neglect, resulting from social prejudice. These women used medicalised prenatal and birthing health care to increase their chance of acquiring a caesarean section, particularly if they had social power in the home. Both social power and women's behaviour towards seeking medicalised health care remained significantly associated with type of birth after controlling for family income and maternal education. Conclusions Fear of substandard care is behind many poor women's preferences for a caesarean section. Variables pertaining to women's role in the process of redefining and negotiating medical risks were much stronger correlates of caesarean section rates than income or education. The unequal distribution of medical technology has altered concepts of good and normal birthing. Arguments supporting interventionist birthing for all on the basis of equal access to health care must be reviewed. What is already known on this topicWomen's preferences for caesarean sections are understood to result from lack of knowledge and psychological aptitude to

To determine the risks and benefits of an elective Caesarean section (CS) at term in healthy nulliparous women. We conducted a population-based cohort study of deliveries between 1994 and 2002. Using bivariate and multivariable techniques, we compared maternal and neonatal outcomes in healthy nulliparous women who had undergone elective pre-labour CS (using breech presentation as a surrogate) with those in women who had undergone spontaneous labour with anticipated vaginal delivery (SL) at full term. There were 1046 deliveries in the pre-labour CS group and 38 021 in the SL group. Life-threatening maternal morbidity was similar in each group. Life-threatening neonatal morbidity was decreased in the CS group (RR 0.34; 99% CI 0.12 to 0.97). Subgroup analysis of the SL group by mode of delivery demonstrated the increased neonatal risk was associated with operative vaginal delivery and intrapartum CS but not spontaneous vaginal delivery. An elective pre-labour Caesarean section in a nulliparous woman at full term decreased the risk of life-threatening neonatal morbidity compared with spontaneous labour with anticipated vaginal delivery. However, the 63% of women with spontaneous labour who achieved a spontaneous vaginal delivery would not have benefited from delivery by Caesarean section. Further research is needed to better identify women with an increased likelihood of an operative vaginal or intrapartum Caesarean section, as this may assist maternity caregivers in decision-making about childbirth. Further research is also needed to determine if these findings can be confirmed in a prospective study.

Caesarean section is associated with weaker newborn suction pressure. This nonblinded, randomized trial explored the effect of suction pressures generating by a breast pump on mothers' onset of lactation and milk supply after caesarean section. A high pressure group (-150 mmHg), a low pressure group (-100 mmHg), and a control group (none) were generated under computer random assignment with concealed allocation in 2 tertiary hospitals. The breast pumping began within 2 hr after caesarean operation (6 times a day and 30 min per time) until onset of lactation. The primary outcomes were the timing of onset of lactation, milk supply, and mother's satisfaction in lactation, using both intention-to-treat and per-protocol analyses. The secondary endpoints were the pumping-related pain, nipple injury, and maternal fatigue. All 164 women randomized were included in analysis. The breast pumping at -150 mmHg optimally advanced the timing of the onset of lactation and increased daytime milk supply. The pumping also appeared to boost mothers' confidence in lactation. The results in the per-protocol population (n = 148) were consistent with those of intention-to-treat population (n = 164). However, the pumping aggravated maternal nipple pain and fatigue, though there was no statistical significance. The findings suggest that a higher pumping pressure within the range of normal vaginally born infant suction could promote onset of lactation and milk supply among mothers giving birth by caesarean section. The pumping could also enhance mothers' confidence in breastfeeding. © 2017 John Wiley & Sons Ltd.

Pregnant women who have previously had a caesarean birth and who have no contraindication for vaginal birth after caesarean (VBAC) may need to decide whether to choose between a repeat caesarean birth or to commence labour with the intention of achieving a VBAC. Women need information about their options and interventions designed to support decision-making may be helpful. Decision support interventions can be implemented independently, or shared with health professionals during clinical encounters or used in mediated social encounters with others, such as telephone decision coaching services. Decision support interventions can include decision aids, one-on-one counselling, group information or support sessions and decision protocols or algorithms. This review considers any decision support intervention for pregnant women making birth choices after a previous caesarean birth. To examine the effectiveness of interventions to support decision-making about vaginal birth after a caesarean birth.Secondary objectives are to identify issues related to the acceptability of any interventions to parents and the feasibility of their implementation. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2013), Current Controlled Trials (22 July 2013), the WHO International Clinical Trials Registry Platform Search Portal (ICTRP) (22 July 2013) and reference lists of retrieved articles. We also conducted citation searches of included studies to identify possible concurrent qualitative studies. All published, unpublished, and ongoing randomised controlled trials (RCTs) and quasi-randomised trials with reported data of any intervention designed to support pregnant women who have previously had a caesarean birth make decisions about their options for birth.

Objective: This study explores the basic demographic characteristics of expectant mothers in the context of their intentions regarding mode of delivery, in particular, the preference for caesarean delivery, and analyzes the social and psychological factors that influence delivery preference. Method: A cross-sectional survey of pregnant women was conducted during June to August in 2015. This study adopted a stratified sampling method, and 16 representative hospitals in five provinces of China were included. Results: 1755 and 590 of expectant mothers in their first and second pregnancies, respectively, were enrolled in this study. 354 (15.10%) intended to deliver by caesarean section and 585 (24.95%) participants were uncertain prior to delivery. 156 (8.89%) of expectant mothers in their first pregnancy and 198 (33.56%) expectant mothers in their second pregnancy intended to deliver by caesarean section. Ordinal logistic regression analysis found that nationality, parity, trimester of pregnancy, and advanced maternal age were factors associated with intention to deliver by caesarean (ordered logistic regression/three-level caesarean delivery intention criterion; odds ratios p < 0.05). Conclusions: 8.89% of first pregnancy expectant mothers and 33.56% of second pregnancy expectant mothers intended to deliver by caesarean section. Any intervention program to reduce the rate of Caesarean delivery should focus on the Han population, older pregnant women, and expectant mothers in their second pregnancy, at an early gestation.

To investigate the demographic and obstetric factors associated with the uptake and success rate of vaginal birth after caesarean section (VBAC). Cohort study using data from Hospital Episode Statistics. English National Health Service. Women whose first birth resulted in a live singleton delivery by caesarean section between 1 April 2004 and 31 March 2011, and who had a second birth before 31 March 2012. Logistic regression to estimate adjusted odds ratios (OR). Attempted and successful VBAC. Among the 143,970 women in the cohort, 75,086 (52.2%) attempted a VBAC for their second birth. Younger women, those of non-white ethnicity and those living in a more deprived area had higher rates of attempted VBAC. Overall, 47,602 women (63.4%) who attempted a VBAC had a successful vaginal birth. Younger women and women of white ethnicity had higher success rates. Black women had a particularly low success rate (OR, 0.54; 95% confidence interval [CI], 0.50-0.57). Women who had an emergency caesarean section in their first birth also had a lower VBAC success rate, particularly those with a history of failed induction of labour (OR, 0.59; 95% CI, 0.53-0.67). In this national cohort, just over one-half of women with a primary caesarean section who were eligible for a trial of labour attempted a VBAC for their second birth. Of these, almost two-thirds successfully achieved a vaginal delivery. © 2013 Royal College of Obstetricians and Gynaecologists.

Objective: To assess the effects of platelet rich plasma (PRP) with chitosan biodegradable film on full thickness wound healing in rat. Methods: This was an experimental study being performed in 2015 during a 4-month period. Twenty-four male white Wistar rats were divided into four groups of 12 rats each, randomly: Control group (SHAM) with creation of wounds and no treatment, PRP group with creation of wounds and application of one milliliter PRP, Chitosan group (CHIT) with dressing the wound with chitosan and CHIT/PRP group with application of one mL PRPand dressing the wound with chitosan. The wounds were created by cutting healthy skin.Wound size was measured on 6, 9, 12, 15, 18 and 21 post surgery and was compared between groups. Results: Reduction in wound area, hydroxyproline contents and biomechanical parametersindicated there was significant difference (p=0.001) between group CHIT/PRP and other groups. Biomechanical testing was performed on day 9 post surgery in incisional model. Quantitative histological studies and mean rank of the qualitative studies demonstrated that there was significant difference (p<0.001) between group CHIT/PRP and other groups. Conclusion: PRP with chitosan have beneficial effects on wounds repair and could be suggested for treating various types of wounds in animals and human being. PMID:27162924

Wound Microbiology and Associated Approaches to Wound Management

The majority of dermal wounds are colonized with aerobic and anaerobic microorganisms that originate predominantly from mucosal surfaces such as those of the oral cavity and gut. The role and significance of microorganisms in wound healing has been debated for many years. While some experts consider the microbial density to be critical in predicting wound healing and infection, others consider the types of microorganisms to be of greater importance. However, these and other factors such as microbial synergy, the host immune response, and the quality of tissue must be considered collectively in assessing the probability of infection. Debate also exists regarding the value of wound sampling, the types of wounds that should be sampled, and the sampling technique required to generate the most meaningful data. In the laboratory, consideration must be given to the relevance of culturing polymicrobial specimens, the value in identifying one or more microorganisms, and the microorganisms that should be assayed for antibiotic susceptibility. Although appropriate systemic antibiotics are essential for the treatment of deteriorating, clinically infected wounds, debate exists regarding the relevance and use of antibiotics (systemic or topical) and antiseptics (topical) in the treatment of nonhealing wounds that have no clinical signs of infection. In providing a detailed analysis of wound microbiology, together with current opinion and controversies regarding wound assessment and treatment, this review has attempted to capture and address microbiological aspects that are critical to the successful management of microorganisms in wounds.

There is a spectrum/continuum of adult human wound healing outcomes ranging from the enhanced (nearly scarless) healing observed in oral mucosa to scarring within skin and the nonhealing of chronic skin wounds. Central to these outcomes is the role of the fibroblast. Global gene expression profiling utilizing microarrays is starting to give insight into the role of such cells during the healing process, but no studies to date have produced a gene signature for this wound healing continuum. Microarray analysis of adult oral mucosal fibroblast (OMF), normal skin fibroblast (NF), and chronic wound fibroblast (CWF) at 0 and 6 hours post-serum stimulation was performed. Genes whose expression increases following serum exposure in the order OMF < NF < CWF are candidates for a negative/impaired healing phenotype (the dysfunctional healing group), whereas genes with the converse pattern are potentially associated with a positive/preferential healing phenotype (the enhanced healing group). Sixty-six genes in the enhanced healing group and 38 genes in the dysfunctional healing group were identified. Overrepresentation analysis revealed pathways directly and indirectly associated with wound healing and aging and additional categories associated with differentiation, development, and morphogenesis. Knowledge of this wound healing continuum gene signature may in turn assist in the therapeutic assessment/treatment of a patient's wounds. PMID:24844339

Silver nanoparticles (AgNPs) were successfully synthesized by a chemical reduction method, physico-chemically characterized and their effect on wound-healing activity in zebrafish was investigated. The prepared AgNPs were circular-shaped, water soluble with average diameter and zeta potential of 72.66 nm and -0.45 mv, respectively. Following the creation of a laser skin wound on zebrafish, the effect of AgNPs on wound-healing activity was tested by two methods, direct skin application (2 μg/wound) and immersion in a solution of AgNPs and water (50 μg/L). The zebrafish were followed for 20 days post-wounding (dpw) by visual observation of wound size, calculating wound healing percentage (WHP), and histological examination. Visually, both direct skin application and immersion AgNPs treatments displayed clear and faster wound closure at 5, 10 and 20 dpw compared to the controls, which was confirmed by 5 dpw histology data. At 5 dpw, WHP was highest in the AgNPs immersion group (36.6%) > AgNPs direct application group (23.7%) > controls (18.2%), showing that WHP was most effective in fish immersed in AgNPs solution. In general, exposure to AgNPs induced gene expression of selected wound-healing-related genes, namely, transforming growth factor (TGF-β), matrix metalloproteinase (MMP) -9 and -13, pro-inflammatory cytokines (IL-1β and TNF-α) and antioxidant enzymes (superoxide dismutase and catalase), which observed differentiation at 12 and 24 h against the control; but the results were not consistently significant, and many either reached basal levels or were down regulated at 5 dpw in the wounded muscle. These results suggest that AgNPs are effective in acceleration of wound healing and altered the expression of some wound-healing-related genes. However, the detailed mechanism of enhanced wound healing remains to be investigated in fish. Copyright © 2017 Elsevier Ltd. All rights reserved.

The development of molecular biology and other new biotechnologies helps us to recognize the wound healing and non-healing wound of skin in the past 30 years. This review mainly focuses on the molecular biology of many cytokines (including growth factors) and other molecular factors such as extracellular matrix (ECM) on wound healing. The molecular biology in cell movement such as epidermal cells in wound healing was also discussed. Moreover many common chronic wounds such as pressure ulcers, leg ulcers, diabetic foot wounds, venous stasis ulcers, etc. usually deteriorate into non-healing wounds. Therefore the molecular biology such as advanced glycation end products (AGEs) and other molecular factors in diabetes non-healing wounds were also reviewed.

DEVELOPMENT OF A NEXT-GENERATION ANTIMICROBIAL WOUND DRESSING.

PubMed

Metcalf, Daniel; Parsons, David; Bowler, I Philip

2016-03-01

Delayed wound healing due to infection is a burden on healthcare systems, and the patient and caregiver alike. An emerging factor in infection and delayed healing is the presence development of biofilm in wounds. Biofilm is communities of microorganisms, protected by an extracellular matrix of slime in the wound, which can tolerate host defences and applied antimicrobials such as antibiotics or antimicrobial dressings. A growing evidence base exists suggesting that biofilm exists in a majority of chronic wounds, and can be a precursor to infection while causing delayed healing itself. In vivo models have demonstrated that the inflammatory, granulation and epithelialization processes of normal wound healing are impaired by biofilm presence. The challenge in the development of a new antimicrobial wound dressing was to make standard antimicrobial agents more effective against biofilm, and this was answered following extensive biofilm research and testing. A combination of metal chelator, surfactant and pH control displayed highly synergistic anti-biofilm action with 1.2% ionic silver in a carboxymethylcellulose dressing. Its effectiveness was challenged and proven in complex in vitro and in vivo wound biofilm models, followed by clinical safety and performance demonstrations in a 42-patient study and 113 clinical evaluations. Post-market surveillance was conducted on the commercially available dressing, and in a 112-case evaluation, the dressing was shown to effectively manage exudate and suspected biofilm while shifting difficult-to-heal wounds onto healing trajectories, after an average of 4 weeks of new dressing use in otherwise standard wound care protocols. This was accompanied by a low frequency of dressing related adverse events. In a second evaluation, clinical signs of infection and wound dimension data, before and after the evaluations, were also available. Following an average of 5.4 weeks of dressing use, all signs of clinical infection were reduced, from

To analyze content related to chronic wounds in nursing degree programs in Spain. Cross-sectional descriptive study. Course descriptions available for online access during June and July of 2012 were reviewed for the 114 centers in Spain that offer a nursing degree, according to the official Registry of Universities, Centers, and Titles. Of the 114 centers with degree programs, 95 (83.3%) post course content online, which make it possible to analyze 2,258 courses. In 60 (63.1%) of these centers, none of the courses included the concept of pressure ulcer prevention, and the course content posted by 36 (37.9%) centers made no mention of their treatment. None of the course descriptions contained any reference to pain management in patients with chronic wounds. Of the 728 elective courses analyzed, only one was related to chronic wounds. This review of available information about nursing degree programs in Spain indicates that pain management in patients with chronic wounds is not addressed in any course, and more courses consider the treatment of pressure ulcers than their prevention. Degree programs responsible for the training of future nurses should be reviewed and revised as needed to ensure that graduates have acquired minimum basic competencies in the prevention and treatment of chronic wounds that help to decrease the theory-practice gap in this field. © 2014 Sigma Theta Tau International.

Estimation of blood haemoglobin concentration using the HemoCue during caesarean section: the effect of sampling site.

PubMed

Richards, N A; Boyce, H; Yentis, S M

2010-01-01

Haemoglobin concentration measured using the HemoCue is accurate for capillary and venous/arterial blood, provided the recommended sampling method is strictly observed. Analysis of blood, particularly of capillary samples, using the HemoCue is useful during caesarean section. The toe might be preferred to the thumb since it is numb during neuraxial anaesthesia, but whether sampling at either site is accurate in this situation, given the cardiovascular effects of anaesthesia and pregnancy, is not known. We aimed to compare haemoglobin values measured in venous and capillary samples (toe and thumb) during caesarean section under neuraxial anaesthesia. Fifty healthy women having caesarean section under spinal or combined spinal-epidural anaesthesia were included. At the end of surgery, the great toe and thumb (non-i.v. fluid side) were lanced as recommended for a HemoCue reading. A venous blood sample (non-i.v. fluid side) was also taken and sent for formal laboratory measurement and tested with the HemoCue. Bland-Altman analysis was applied to the haemoglobin values. Bias (mean difference) and precision +/- 2 SD were respectively 0.2 +/-1.6 for laboratory vs. toe, 0.1 +/-1.8 for laboratory vs. thumb, and 0.2 +/-1.6 laboratory vs. venous. Our results suggest that in terms of accuracy, the two sites are equally suitable for use during caesarean section under neuraxial anaesthesia. Copyright 2009 Elsevier Ltd. All rights reserved.

Sternal plate fixation for sternal wound reconstruction: initial experience (Retrospective study)

PubMed Central

2011-01-01

Background Median sternotomy infection and bony nonunion are two commonly described complications which occur in 0.4 - 5.1% of cardiac procedures. Although relatively infrequent, these complications can lead to significant morbidity and mortality. The aim of this retrospective study is to evaluate the initial experience of a transverse plate fixation system following wound complications associated with sternal dehiscence with or without infection following cardiac surgery. Methods A retrospective chart review of 40 consecutive patients who required sternal wound reconstruction post sternotomy was performed. Soft tissue debridement with removal of all compromised tissue was performed. Sternal debridement was carried using ronguers to healthy bleeding bone. All patients underwent sternal fixation using three rib plates combined with a single manubrial plate (Titanium Sternal Fixation System®, Synthes). Incisions were closed in a layered fashion with the pectoral muscles being advanced to the midline. Data were expressed as mean ± SD, Median (range) or number (%). Statistical analyses were made by using Excel 2003 for Windows (Microsoft, Redmond, WA, USA). Results There were 40 consecutive patients, 31 males and 9 females. Twenty two patients (55%) were diagnosed with sternal dehiscence alone and 18 patients (45%) with associated wound discharge. Thirty eight patients went on to heal their wounds. Two patients developed recurrent wound infection and required VAC therapy. Both were immunocompromised. Median post-op ICU stay was one day with the median hospital stay of 18 days after plating. Conclusion Sternal plating appears to be an effective option for the treatment of sternal wound dehiscence associated with sternal instability. Long-term follow-up and further larger studies are needed to address the indications, benefits and complications of sternal plating. PMID:21529357

The objective of this study was to determinate the reliability of 3-dimensional wound analyzer (3-DWMD) in the wound area measurement for animal small area in the process of wound healing. Seven Sprague-Dawley rats were used to establish the skin defect model. And the wound area and time consumption were measured on days 0, 5, 10, 15 using 3-DWMD, investigators, and planimetry method. The measurement results using 3-DWMD and investigators were analyzed comparative with that using planimetry method separately. A total 46 wounds, including 32 irregular wounds and regular 14 wounds, were measured. No matter calculating the irregular wounds or the regular wounds, there was no significant difference between 3-DWMD group and planimetry group in measuring wound area (P > 0.05). However, a statistically significant difference was found in time-consuming for measuring wound area between 3-DWMD group and planimetry group (P < 0.001). The same result was found between investigator group and planimetry group (P < 0.001). The 3-DWMD would quickly and accurately obtain the wound area, and its measurement results were consistent with planimetry method. Therefore, such measuring equipment has clinical reference value for measuring precision area of the wound in the process of wound healing.

Annona squamosa L. (Annonaceae), commonly known as custard apple, mainly used for its edible fruit, is also recognised with numerous medicinal properties. As there is no report on the efficacy of this plant for wound healing, we examined the efficacy of ethanolic extract of A. squamosa leaves on wound repair in streptozotocin-nicotinamide-induced diabetic rats. Open excision wounds were made on the back of rats. The drug at a dosage of 100 mg/kg body wt was reconstituted in 200 µl of phosphate buffered saline and applied topically once daily for the treated wounds. The control wounds were left untreated. Wound tissues formed on days 4, 8, 12 and 16 (post-wound) were used to estimate DNA, total protein, total collagen, hexosamine and uronic acid. Levels of lipid peroxides were also evaluated along with tensile strength and period of epithelialisation. A. squamosa L. increased cellular proliferation and collagen synthesis at the wound site as evidenced by increase in DNA, protein and total collagen. The treated wounds were observed to heal much faster as proved by enhanced rates of epithelialisation and wound contraction, which was also confirmed by histopathological examinations. The results strongly substantiate the beneficial effects of the topical application of A. squamosa L. in the acceleration of normal and diabetic wound healing. © 2012 The Authors. © 2012 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

2014-04-01

Wound infiltration with local anaesthetics is commonly used during breast surgery in an attempt to reduce post-operative pain and opioid consumption. The aim of this review was to evaluate the effect of wound infiltration with local anaesthetics compared with a control group on post-operative pain after breast surgery. A systematic review was performed by searching PubMed, Google Scholar, the Cochrane database and Embase for randomised, blinded, controlled trials of wound infiltration with local anaesthetics for post-operative pain relief in female adults undergoing breast surgery. The analgesic effect was evaluated in a qualitative analysis by assessment of significant difference between groups (P < 0.05) in pain scores and supplemental analgesic consumption. Ten trials including 699 patients were included in the final analysis. Three trials investigated mastectomy, four trials partial or segmental mastectomy, and three trials breast reduction, excision of benign lump and unspecified breast surgery, respectively. Six trials demonstrated a small and short-lasting, but statistically significant reduction of post-operative pain scores, and four trials observed a statistically significant reduction in post-operative, supplemental opioid consumption that was, however, of limited clinical relevance. Wound infiltration with local anaesthetics may have a modest analgesic effect in the first few hours after surgery. Pain after breast surgery is, however, generally mild to moderate, and other non-invasive analgesic methods may be preferable in this surgical population. © 2014 The Acta Anaesthesiologica Scandinavica Foundation.

Managing painful chronic wounds: the Wound Pain Management Model.

PubMed

Price, Patricia; Fogh, Karsten; Glynn, Chris; Krasner, Diane L; Osterbrink, Jürgen; Sibbald, R Gary

2007-04-01

Chronic wound pain is not well understood and the literature is limited. Six of 10 patients venous leg ulcer experience pain with their ulcer, and similar trends are observed for other chronic wounds. Chronic wound pain can lead to depression and the feeling of constant tiredness. Pain related to the wound should be handled as one of the main priorities in chronic wound management together with addressing the cause. Management of pain in chronic wounds depends on proper assessment, reporting and documenting patient experiences of pain. Assessment should be based on six critical dimensions of the pain experience: location, duration, intensity, quality, onset and impact on activities of daily living. Holistic management must be based on a safe and effective mix of psychosocial approaches together with local and systemic pain management. It is no longer acceptable to ignore or inadequately document persistent wound pain and not to develop a treatment and monitoring strategy to improve the lives of persons with chronic wounds. Unless wound pain is optimally managed, patient suffering and costs to health care systems will increase.

To evaluate the efficacy and safety of double balloon catheter for induction of labour in Chinese women with one previous caesarean section and unfavourable cervix at term. Retrospective cohort study. A regional hospital in Hong Kong. Women with previous caesarean delivery requiring induction of labour at term and with an unfavourable cervix from May 2013 to April 2014. Primary outcome was to assess rate of successful vaginal delivery (spontaneous or instrument-assisted) using double balloon catheter. Secondary outcomes were double balloon catheter induction-to-delivery and removal-to-delivery interval; cervical score improvement; oxytocin augmentation; maternal or fetal complications during cervical ripening, intrapartum and postpartum period; and risk factors associated with unsuccessful induction. All 24 Chinese women tolerated double balloon catheter well. After double balloon catheter expulsion or removal, the cervix successfully ripened in 18 (75%) cases. The improvement in Bishop score 3 (interquartile range, 2-4) was statistically significant (P<0.001). Overall, 18 (75%) cases were delivered vaginally. The median insertion-to-delivery and removal-to-delivery intervals were 19 (interquartile range, 13.4-23.0) hours and 6.9 (interquartile range, 4.1-10.8) hours, respectively. Compared with cases without, the interval to delivery was statistically significantly shorter in those with spontaneous balloon expulsion or spontaneous membrane rupture during ripening (7.8 vs 3.0 hours; P=0.025). There were no major maternal or neonatal complications. The only factor significantly associated with failed vaginal birth after caesarean was previous caesarean section for failure to progress (P<0.001). This is the first study using double balloon catheter for induction of labour in Asian Chinese women with previous caesarean section. Using double balloon catheter, we achieved a vaginal birth after caesarean rate of 75% without major complications.

Controversy exists as to whether effective spinal anaesthesia can be achieved as quickly as general anaesthesia for a category-1 caesarean section. Sixteen consultants and three fellows in obstetric anaesthesia were timed performing spinal and general anaesthesia for category-1 caesarean section on a simulator. The simulation time commenced upon entry of the anaesthetist into the operating theatre and finished for the spinal anaesthetic at the end of intrathecal injection and for the general anaesthetic when the anaesthetist was happy for surgery to start. In the second clinical part of the study, the time from intrathecal administration to 'adequate surgical anaesthesia' (defined as adequate for start of a category-1 caesarean section) was estimated in 100 elective (category-4) caesarean sections. The median (IQR [range]) times (min:s) for spinal procedure, onset of spinal block and general anaesthesia were 2:56 (2:32-3:32 [1:22-3:50]), 5:56 (4:23-7:39 [2:9-13:32]) and 1:56 (1:39-2:9 [1:13-3:12]), respectively. The limiting factor in urgent spinal anaesthesia is the unpredictable time needed for adequate surgical block to develop.

Baharestani, Mona Mylene; Gabriel, Allen

2011-04-01

The purpose of this study was to examine the clinical outcomes of negative pressure wound therapy (NPWT) using reticulated open-cell foam (ROCF) in the adjunctive management of abdominal wounds with exposed and known infected synthetic mesh. A non randomised, retrospective review of medical records for 21 consecutive patients with infected abdominal wounds treated with NPWT was conducted. All abdominal wounds contained exposed synthetic mesh [composite, polypropylene (PP), or knitted polyglactin 910 (PG) mesh]. Demographic and bacteriological data, wound history, pre-NPWT and comparative post-NPWT, operative procedures and complications, hospital length of stay (LOS) and wound healing outcomes were all analysed. Primary endpoints measured were (1) hospital LOS prior to initiation of NPWT, (2) total time on NPWT, (3) hospital LOS from NPWT initiation to discharge and (4) wound closure status at discharge. A total of 21 patients with abdominal wounds with exposed, infected mesh were treated with NPWT. Aetiology of the wounds was ventral hernia repair (n = 11) and acute abdominal wall defect (n = 10). Prior to NPWT initiation, the mean hospital LOS for the composite, PP and PG meshes were 76 days (range: 21-171 days), 51 days (range: 32-62 days) and 19 days (range: 12-39 days), respectively. The mean hospital LOS following initiation of NPWT for wounds with exposed composite, PP and PG mesh were 28, 31 and 32 days, respectively. Eighteen of the 21 wounds (86%) reached full closure after a mean time of 26 days of NPWT and a mean hospital LOS of 30 days postinitiation of NPWT. Three wounds, all with composite mesh left in situ, did not reach full closure, although all exhibited decreased wound dimensions, granulating beds and decreased surface area exposure of mesh. During NPWT/ROCF, one hypoalbuminemic patient with exposed PP mesh developed an enterocutaneous fistula over a prior enterotomy site. This patient subsequently underwent total mesh extraction, takedown of

Women with a prior caesarean delivery have an increased risk of uterine rupture and for women subsequently requiring induction of labour it is unclear which method is preferable to avoid adverse outcomes. This is an update of a review that was published in 2013. To assess the benefits and harms associated with different methods used to induce labour in women who have had a previous caesarean birth. We searched Cochrane Pregnancy and Childbirth's Trials Register (31 August 2016) and reference lists of retrieved studies. Randomised controlled trials (RCTs) comparing any method of third trimester cervical ripening or labour induction, with placebo/no treatment or other methods in women with prior caesarean section requiring labour induction in a subsequent pregnancy. Two review authors independently assessed studies for inclusion and trial quality, extracted data, and checked them for accuracy. Eight studies (data from 707 women and babies) are included in this updated review. Meta-analysis was not possible because studies compared different methods of labour induction. All included studies had at least one design limitation (i.e. lack of blinding, sample attrition, other bias, or reporting bias). One study stopped prematurely due to safety concerns. Vaginal PGE2 versus intravenous oxytocin (one trial, 42 women): no clear differences for caesarean section (risk ratio (RR) 0.67, 95% confidence interval (CI) 0.22 to 2.03, evidence graded low), serious neonatal morbidity or perinatal death (RR 3.00, 95% CI 0.13 to 69.70, evidence graded low), serious maternal morbidity or death (RR 3.00, 95% CI 0.13 to 69.70, evidence graded low). Also no clear differences between groups for the reported secondary outcomes. The GRADE outcomes vaginal delivery not achieved within 24 hours, and uterine hyperstimulation with fetal heart rate changes were not reported.

Significance: Chronic wounds are a major healthcare burden.The practitioner should have an appropriate understanding of both the etiology of the wound as well as the optimal type of dressings to use. Fundamental wound characteristics may be used to guide the practitioner's choice of dressings. The identification of optimal dressings to use for a particular wound type is an important element in facilitating wound healing. Recent Advances: Researchers have sought to design wound dressings that aim to optimize each stage in the healing process. In addition, dressings have been designed to target and kill infection-causing bacteria, with the incorporation of antimicrobial agents. Critical Issues: Chronic wounds are frequently dynamic in presentation, and the numerous wound dressings available make dressing selection challenging for the practitioner. Choosing the correct dressing decreases time to healing, provides cost-effective care, and improves patient quality of life. Future Directions: Research into the mechanisms of wound healing has enhanced our ability to heal chronic wounds at a faster rate through the use of moisture-retentive dressings. Newer dressings are incorporating the use of nanotechnology by incorporating miniature electrical sensors into the dressing. These dressings are engineered to detect changes in a wound environment and alert the patient or practitioner by altering the color of the dressing or sending a message to a smartphone. Additional investigations are underway that incorporate biologic material such as stem cells into dressings. PMID:26858913

Objectives To describe the prevalence and determinants of births by caesarean section in private and public health facilities in underserved communities in South Asia. Design Cross-sectional study. Setting 81 community-based geographical clusters in four locations in Bangladesh, India and Nepal (three rural, one urban). Participants 45 327 births occurring in the study areas between 2005 and 2012. Outcome measures Proportion of caesarean section deliveries by location and type of facility; determinants of caesarean section delivery by location. Results Institutional delivery rates varied widely between settings, from 21% in rural India to 90% in urban India. The proportion of private and charitable facility births delivered by caesarean section was 73% in Bangladesh, 30% in rural Nepal, 18% in urban India and 5% in rural India. The odds of caesarean section were greater in private and charitable health facilities than in public facilities in three of four study locations, even when adjusted for pregnancy and delivery characteristics, maternal characteristics and year of delivery (Bangladesh: adjusted OR (AOR) 5.91, 95% CI 5.15 to 6.78; Nepal: AOR 2.37, 95% CI 1.62 to 3.44; urban India: AOR 1.22, 95% CI 1.09 to 1.38). We found that highly educated women were particularly likely to deliver by caesarean in private facilities in urban India (AOR 2.10; 95% CI 1.61 to 2.75) and also in rural Bangladesh (AOR 11.09, 95% CI 6.28 to 19.57). Conclusions Our results lend support to the hypothesis that increased caesarean section rates in these South Asian countries may be driven in part by the private sector. They also suggest that preferences for caesarean delivery may be higher among highly educated women, and that individual-level and provider-level factors interact in driving caesarean rates higher. Rates of caesarean section in the private sector, and their maternal and neonatal health outcomes, require close monitoring. PMID:25550293

Vitamin C (VitC) or ascorbic acid (AscA), a cofactor for collagen synthesis and a primary antioxidant, is rapidly consumed post-wounding. Parenteral VitC administration suppresses pro-inflammatory responses while promoting anti-inflammatory and pro-resolution effects in human/murine sepsis. We hypothesised that VitC could promote wound healing by altering the inflammatory, proliferative and remodelling phases of wound healing. Mice unable to synthesise VitC (Gulo(-/-) ) were used in this study. VitC was provided in the water (sufficient), withheld from another group (deficient) and supplemented by daily intra-peritoneal infusion (200 mg/kg, deficient + AscA) in a third group. Full thickness excisional wounds (6 mm) were created and tissue collected on days 7 and 14 for histology, quantitative polymerase chain reaction (qPCR) and Western blotting. Human neonatal dermal fibroblasts (HnDFs) were used to assess effects of In conclusion, VitC favorably on proliferation. Histological analysis showed improved wound matrix deposition and organisation in sufficient and deficient +AscA mice. Wounds from VitC sufficient and deficient + AscA mice had reduced expression of pro-inflammatory mediators and higher expression of wound healing mediators. Supplementation of HnDF with AscA induced the expression of self-renewal genes and promoted fibroblast proliferation. VitC favourably impacts the spatiotemporal expression of transcripts associated with early resolution of inflammation and tissue remodelling. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Objective To investigate the neonatal effect and placental transfer of dexmedetomidine during caesarean section under epidural anaesthesia. Methods Forty parturients with a single newborn who were scheduled for caesarean section were enrolled. Patients received 0.5 µg/kg dexmedetomidine 10 min after epidural anaesthesia, followed by 0.5 µg/kg/h until abdominal closure (Dex group) or infusion of normal saline (NS group). Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were monitored before infusion (T0), 10 min after infusion (T1), at delivery (T2), and at the end of the operation (T3). Umbilical vein and artery blood was collected. Apgar scores were evaluated at 1 and 5 min after delivery. Results SBP, DBP, and HR in the Dex group were decreased at T3 compared with T0 (116 ± 10.4 vs 111 ± 9.2 mmHg, 74 ± 6.7 vs 66 ± 7.9 mmHg, 91 ± 12.1 vs 71 ± 8.4 beats/min, respectively, P < 0.05). HR was lower at T1, T2, and T3 in the Dex group compared with the NS group (P < 0.05). There were no significant differences in blood gases and Apgar scores between the groups (P > 0.05). Conclusion Dexmedetomidine during caesarean section under epidural anaesthesia is beneficial to parturients. The placental transfer rate is 0.68. PMID:28449631

BACKGROUND: Disrupted vasculature and high energy-demand to support processing and regeneration of wounded tissue are typical characteristics of a wound site. Oxygen delivery is a critical element for the healing of wounds. Clinical experience with adjunctive hyperbaric oxygen therapy in the treatment of chronic wounds have shown that wound hyperoxia increases wound granulation tissue formation and accelerates wound contraction and secondary closure. Nevertheless, the physiologic basis for this modality remains largely unknown. Also, systemic hyperbaric oxygen therapy is associated with risks related to oxygen toxicity. Topical oxygen therapy represents a less explored modality in wound care. The advantages of topical oxygen therapy include low cost, lack of systemic oxygen toxicity, and the ability to receive treatment at home, making the benefits of oxygen therapy available to a much larger population of patients. MATERIALS AND METHODS: Over 9 months, seven surgeons treated 58 wounds in 32 patients with topical oxygen with follow-up ranging from 1 to 8 months. The data presented herein is a retrospective analysis of the results we have achieved using topical oxygen on complex wounds. RESULTS: Thirty-eight wounds in 15 patients healed while on topical oxygen. An additional five wounds in five patients had preoperative oxygen therapy; all wounds initially healed postoperatively. In two patients, wounds recurred post-healing. In ten wounds, topical oxygen had no effect; and two of those patients went on to require limb amputation. There were no complications attributable to topical oxygen. Three patients died during therapy and one died in the first postoperative month from underlying medical problems. Two patients were lost to follow-up. CONCLUSIONS: In this case series, topical oxygen had no detrimental effects on wounds and showed beneficial indications in promoting wound healing.

Epidermal aquaporin-3 is increased in the cutaneous burn wound

Introduction Aquaporins (AQP) are a family of transmembrane proteins that transport water and small solutes such as glycerol across cell membranes. It is a mediator of transcellular water flow and plays an important role in maintaining intra/extracellular fluid homeostasis by facilitating water transport in response to changing osmotic gradients. In the skin, AQPs permit rapid, regulated, and selective water permeability and have been demonstrated to play a role in skin hydration, cell proliferation, migration, immunity, and wound healing. However, the expression of AQP-3 in the cutaneous burn wound has never been elucidated. We sought to assess the expression of AQP-3 in patients with burn wounds. Methods A fresh full thickness biopsy sample was taken from the center of the burn wound, the burn wound edge, and the graft donor site in 7 patients (n = 21), approximately 3–7 days post injury. Fixed, paraffin embedded sections were stained using AQP-3 specific antibody and examined by immunofluorescence. Fresh samples were processed to quantify AQP-3 protein expression with Western blot analysis. Results The central portion of the burn wound revealed destruction of the epidermis and dermis with no AQP-3 present. Along the burn wound edge where the epidermal architecture was disrupted, there was robust AQP-3 staining. Western blot analysis demonstrated deeper staining along the burn wound edge compared to unburned skin (control). Quantification of the protein shows a significant amount of AQP-3 expression along the burn wound edge (3.6 ± 0.34) compared to unburned skin (2.1 ± 0.28, N = 7, *p < 0.05). There is no AQP-3 expression in the burn wound center. Conclusion AQP-3 expression is increased in the burn wound following injury. While its role in wound healing has been defined, we report for the first time the effect of cutaneous burns on AQP-3 expression. Our data provides the first step in determining its functional role in burn wounds. We hypothesize that

To evaluate the implementation of the Champions for Skin Integrity model on facilitating uptake of evidence-based wound management and improving skin integrity in residents of aged care facilities. The incidence of skin tears, pressure injuries and leg ulcers increases with age, and such wounds can be a serious issue in aged care facilities. Older adults are not only at higher risk for wounds related to chronic disease but also injuries related to falls and manual handling requirements. A longitudinal, pre-post design. The Champions for Skin Integrity model was developed using evidence-based strategies for transfer of evidence into practice. Data were collected before and six months after implementation of the model. Data on wound management and skin integrity were obtained from two random samples of residents (n = 200 pre; n = 201 post) from seven aged care facilities. A staff survey was also undertaken (n = 126 pre; n = 143 post) of experience, knowledge and evidence-based wound management. Descriptive statistics were calculated for all variables. Where relevant, chi-square for independence or t-tests were used to identify differences between the pre-/postdata. There was a significant decrease in the number of residents with a wound of any type (54% pre vs 43% post, χ 2 4·2, p = 0·041), as well as a significant reduction in specific wound types, for example pressure injuries (24% pre vs 10% post, χ 2 14·1, p < 0·001), following implementation of the model. An increase in implementation of evidence-based wound management and prevention strategies was observed in the postimplementation sample in comparison with the preimplementation sample. This included use of limb protectors and/or protective clothing 6% pre vs 20% post (χ 2 17·0, p < 0·001) and use of an emollient or soap alternative for bathing residents (50% pre vs 74% post, χ 2 13·9, p = 0·001). Implementation of the model in this sample fostered an increase in implementation of

Gum chewing has been reported to enhance bowel motility and reduce postoperative ileus (POI). However, the efficacy remains imprecise for women following caesarean section. To summarise and evaluate the current evidence for postoperative gum chewing on the recovery of bowel function following caesarean section. We searched studies from the following electronic databases: PubMed, EMBASE, SCOPUS and Cochrane Library from inception to 30 May 2013. We included randomised controlled trials (RCTs) of women after caesarean section; these RCTs should compared gum chewing with no gum chewing and reported on at least one of the outcomes: time to flatus, time to bowel sound, time to passing stool and length of hospital stay (LOS). Study outcomes were presented as mean differences (for continuous data) with 95% confidence interval (95% CI). The risk of bias in the study results was assessed using the assessment tool from the Cochrane Handbook. Six RCTs including 939 women were included in our meta-analysis. The pooled results demonstrated that gum chewing is superior to no gum chewing with a reduction of 6.42 hours (95% CI -7.55 to -5.29) for time to first flatus, 3.62 hours (95% CI -6.41 to -0.83) for time to first bowel sound, 6.58 hours (95% CI -10.10 to -3.07) for time to first stool and 5.94 hours (95% CI -9.39 to -2.49) for LOS. In addition, no evidence emerged for any side effects caused by gum chewing. The current evidence suggests that gum chewing is associated with early recovery of bowel motility and shorter LOS for women after caesarean section. This safe and inexpensive intervention should be included in routine postoperative care following a caesarean section. © 2014 Royal College of Obstetricians and Gynaecologists.

Chronic wounds are commonly associated with high morbidity rates due to the patient's need of frequent dressing changes and repeated visits to the outpatient wound clinic. Furthermore, chronic wounds are often characterised by severe pain, which can cause significant disability to the patient. New technologies aim to develop an optimal device to reduce discomfort of the patient and to heal wounds. The device Rexon-age ® is introduced for the first time in wound healing, and preliminary data on clinical and histological results are shown. From April 2014 to April 2015, 11 patients - 7 females and 4 males - were enrolled in the present study. The study was conducted at the Plastic and Reconstructive Institute of the Università degli Studi di Torino, Città della Salute e della Scienza of Torino, Italy. For histological characterisation, pre- and post-treatment biopsies on the wound bed were performed. Data regarding age, gender, weight, height, comorbidity, drug therapy and topical pre-treatment and dressings of the wound were collected as well. Moreover, local factors regarding the wound data were as follows: aetiology, time of the wound formation until first Rexon-age treatment, wound dimensions, wound bed, moisture, margins and anatomical region of the wound. A visual analogue scale (VAS) was used to monitor the pain before and after each treatment. Rexon-age treatment resulted in improvement in granulation tissue and wound contraction. Moreover, a significant reduction of pain was observed with the reduction of painkillers drug usage. Among these Rexon-age-treated patients, three patients displayed 60-80% reduction in pain intensity, and two patients showed complete pain relief. In outpatient follow-up appointments, we registered long-term durability of pain relief. As assessed by histological analyses, post-treatment biopsies of all nine patients revealed a decreased amount of inflammatory cells and lower expression levels of metalloproteinases (e.g. MMP9). We

Low molecular weight fucoidan (LMF) has been reported to possess anti-inflammatory and antioxidant activities. Thus, we examined the effects of LMF extracted from Undaria pinnatifida on dermal wounds. Five round dermal wounds were created on the dorsal back of rats, and they were then treated topically with distilled water (DW), Madecasol Care™ (MC) or LMF at 200, 100 and 50 mg/mL, twice a day for a week. There were dose-dependent increases in wound contraction in the groups receiving LMF but not in the MC group, compared with the DW. Histopathological examination revealed that LMF treatment accelerated wound healing, which was supported by increases in granular tissue formation on day four post-treatment but a decrease on day seven, accompanied by an evident reduction in inflammatory cells. In the LMF-treated wounds, collagen distribution and angiogenesis were increased in the granular tissue on days four and seven post-treatment. Immunoreactive cells for transforming growth factor-β1, vascular endothelial growth factor receptor-2 or matrix metalloproteinases 9 were also increased, probably due to tissue remodeling. Furthermore, LMF treatment reduced lipid peroxidation and increased antioxidant activities. These suggested that LMF promotes dermal wound healing via complex and coordinated antioxidant, anti-inflammatory and growth factor-dependent activities. PMID:28387729

Negative pressure wound therapy (NPWT) is a useful wound dressing that can be applied to a wide variety of wounds. Patients with ischaemic wounds, however, may experience further necrosis with NPWT at the commonly recommended pressure of -125 mm Hg. We hypothesized that with a suction pressure of -125 mm Hg, tissue pressure will likely occlude most of the capillaries adjacent to the wound edge. Therefore, we treated three patients with ischaemic wounds using low-pressure NPWT at -50 mm Hg. All wounds healed successfully without further necrosis at the wound edge. Crown Copyright © 2011.

The drug pirfenidone has been shown to slow the progression and decrease mortality of idiopathic pulmonary fibrosis (IPF). Its exact mechanism is unknown, but it likely inhibits pro-fibrotic cytokine transforming growth factor beta, a known contributor to wound healing. We evaluated whether patients taking pirfenidone until lung transplantation had increased risk of impaired wound healing post-transplant. This information could determine whether pirfenidone should be discontinued prior to listing to allow for a wash-out period. We retrospectively reviewed patients who underwent lung transplantation for pulmonary fibrosis at Norton Thoracic Institute in Phoenix, Arizona, from January 2014 to December 2015. We describe 18 patients who took pirfenidone up to a month before transplant. Aside from one patient who experienced sternal dehiscence due to a surgical issue, all remaining patients did well with no evidence of airway dehiscence. Each of these 17 patients had been on pirfenidone for at least 30 days; nine patients had been on pirfenidone for over 90 days. Baseline characteristics including age, sex, body mass index, renal function, liver function, glucose level, pre-transplant corticosteroid use, and post-transplant immunosuppressant therapy were similar. In our experience, pirfenidone may be safely continued until lung transplantation. Only one patient in our series experienced impaired wound healing related to a surgical issue, even when pirfenidone was continued until lung transplantation. We found no evidence of impaired wound healing or airway complications after lung transplantation in patients who were treated with pirfenidone before lung transplantation.

Hypotension during spinal anaesthesia for Caesarean delivery is a result of decreased vascular resistance due to sympathetic blockade and decreased cardiac output due to blood pooling in blocked areas of the body. Change in baseline peripheral vascular tone due to pregnancy may affect the degree of such hypotension. The perfusion index (PI) derived from a pulse oximeter has been used for assessing peripheral perfusion dynamics due to changes in peripheral vascular tone. The aim of this study was to examine whether baseline PI could predict the incidence of spinal anaesthesia-induced hypotension during Caesarean delivery. Parturients undergoing elective Caesarean delivery under spinal anaesthesia with hyperbaric bupivacaine 10 mg and fentanyl 20 μg were enrolled in this prospective study. The correlation between baseline PI and the degree of hypotension during spinal anaesthesia and also the predictability of spinal anaesthesia-induced hypotension during Caesarean delivery by PI were investigated. Baseline PI correlated with the degree of decreases in systolic and mean arterial pressure (r=0.664, P<0.0001 and r=0.491, P=0.0029, respectively). The cut-off PI value of 3.5 identified parturients at risk for spinal anaesthesia-induced hypotension with a sensitivity of 81% and a specificity of 86% (P<0.001). The change of PI in parturients with baseline PI ≤ 3.5 was not significant during the observational period, while PI in parturients with baseline PI>3.5 demonstrated marked decreases after spinal injection. We demonstrated that higher baseline PI was associated with profound hypotension and that baseline PI could predict the incidence of spinal anaesthesia-induced hypotension during Caesarean delivery.

Myofibroblasts play a key role in wound closure but their origin is poorly understood. To investigate whether fibrocytes contribute to myofibroblast population, we examined the phenotype of fibrocytes and myofibroblasts present in the wounded skin of BALB/c mice. During wound healing, there was a marked increase in the number of cells expressing the myofibroblast marker {alpha}-smooth muscle actin in the granulation tissue. Between 4 and 7 days post-wounding, more than 50% of these cells also expressed the CD13 antigen. CD13{sup +}/collagen I{sup +} fibrocytes could be isolated at an early stage of the healing process from digested fragments of woundedmore » tissue by fluorescence-activated cell sorting. Like authentic fibrocytes, these cells were also CD45{sup +}/CD34{sup +}/CD14{sup -}. Between 4 and 7 days post-injury, 61.4% of the isolated fibrocytes were found to express {alpha}-smooth muscle actin gene and protein. We repeated similar experiments in female mice that had received a male whole bone marrow transplant after total body irradiation. By in situ hybridization, we identified the Y chromosome in the nuclei of the majority of fibrocytes isolated from the wounded tissue of these animals. Our data indicate that circulating fibrocytes contribute to the myofibroblast population in the wounded skin and that they originate from the bone marrow.« less

Pain is the key concern of women after caesarean delivery that may interfere with breastfeeding. The aim of this study was to assess effect of ketofol (ketamine/propofol combination) on pain and complication after caesarean delivery under spinal anaesthesia. In this randomized double-blind clinical trial, 92 parturient scheduled for elective caesarean delivery under spinal anaesthesia were included. The simple random sampling method was used to place subjects in four groups of ketamine (0.25 mg/kg), propofol (0.25 mg/kg), ketofol (25 mg ketamine plus 25 mg propofol) and placebo (saline). The drugs were administered intravenously immediately after clamping the umbilical cord. Visual Analog Scale (VAS) was used to determine the intensity of pain. Complications after surgery including shivering, nausea and vomiting as well as onset of breastfeeding were recorded. The mean score of pain, morphine consumption and time of breastfeeding in the ketofol group were significantly lower than other groups at various intervals (p<0.05, p<0.001). The frequencies of shivering, nausea, vomiting, retention and pruritus in the ketofol group were significantly lower than other groups (p<0.001, p<0.05). The effective role of ketofol on reducing pain and complication after caesarean delivery indicated that it can be considered as a safe and alternative drug in these patients.

The last two decades witnessed the development of numerous innovative regimens for the management of patients with abnormally healing and infected wounds. Growth factors, negative pressure wound therapy (NPWT) and antiseptic dressings containing silver are examples of methods with best documented efficacy, being widely used in the treatment of acute and chronic post-traumatic wounds, burns and ulcers of various etiology. As far as obstetrics and gynecology are concerned, prevention and treatment of infected, hard-to-heal postoperative wounds is of crucial importance. This article reviews the available literature to discuss the possibilities for use, efficacy and cost-effectiveness of growth factors, NPWT and silver dressings in the treatment of difficult-to-heal postsurgical wounds in obstetrics and gynecology. An extensive search of the English and Polish literature via PubMed and EMBASE databases was undertaken for articles published between January 1960 and April 30, 2014 to identify articles that described and assessed use, efficacy and cost-effectiveness of growth factors, silver dressings and NPWT in patients with hard-to-heal postoperative wounds following obstetric or gynecological surgery. Literature review regarding the use of growth factors, NPWT and silver dressings suggests that these methods may play an important role in the management of wounds after invasive obstetric and gynecological procedures. Obese patients, patients after vulvectomy or prior radiation therapy may benefit most, however, due to non-numerous randomized reports, prospective studies on the use of above-mentioned methods in the treatment of postsurgical wounds following obstetric and gynecological interventions are required.

Introduction Deep burn wounds undergo a dynamic process known as wound progression that results in a deepening and extension of the initial burn area. The zone of stasis is more likely to develop more severe during wound progression in the presence of hypoperfusion. Hydrogen has been reported to alleviate injury triggered by ischaemia/reperfusion and burns in various organs by selectively quenching oxygen free radicals. The aim of this study was to investigate the possible protective effects of hydrogen against early burn-wound progression. Methods Deep-burn models were established through contact with a boiled, rectangular, brass comb for 20 s. Fifty-six Sprague-Dawley rats were randomly divided into sham, burn plus saline, and burn plus hydrogen-rich saline (HS) groups with sacrifice and analysis at various time windows (6 h, 24 h, 48 h) post burn. Indexes of oxidative stress, apoptosis and autophagy were measured in each group. The zone of stasis was evaluated using immunofluorescence staining, ELISA, and Western blot to explore the underlying effects and mechanisms post burn. Results The burn-induced increase in malondialdehyde was markedly reduced with HS, while the activities of endogenous antioxidant enzymes were significantly increased. Moreover, HS treatment attenuated increases in apoptosis and autophagy postburn in wounds, according to the TUNEL staining results and the expression analysis of Bax, Bcl-2, caspase-3, Beclin-1 and Atg-5 proteins. Additionally, HS lowered the level of myeloperoxidase and expression of TNF-α, IL-1β, and IL-6 in the zone of stasis while augmenting IL-10. The elevated levels of Akt phosphorylation and NF-κB p65 expression post burn were also downregulated by HS management. Conclusion Hydrogen can attenuate early wound progression following deep burn injury. The beneficial effect of hydrogen was mediated by attenuating oxidative stress, which inhibited apoptosis and inflammation, and the Akt/NF-κB signalling pathway may be

Pathological scarring in wounds is a prevalent clinical outcome with limited prognostic options. The objective of this study was to investigate whether cellular signaling proteins could be used as prognostic biomarkers of pathological scarring in traumatic skin wounds. We used our previously developed and validated computational model of injury-initiated wound healing to simulate the time courses for platelets, 6 cell types, and 21 proteins involved in the inflammatory and proliferative phases of wound healing. Next, we analysed thousands of simulated wound-healing scenarios to identify those that resulted in pathological (i.e., excessive) scarring. Then, we identified candidate proteins that were elevated (or decreased) at the early stages of wound healing in those simulations and could therefore serve as predictive biomarkers of pathological scarring outcomes. Finally, we performed logistic regression analysis and calculated the area under the receiver operating characteristic curve to quantitatively assess the predictive accuracy of the model-identified putative biomarkers. We identified three proteins (interleukin-10, tissue inhibitor of matrix metalloproteinase-1, and fibronectin) whose levels were elevated in pathological scars as early as 2 weeks post-wounding and could predict a pathological scarring outcome occurring 40 days after wounding with 80% accuracy. Our method for predicting putative prognostic wound-outcome biomarkers may serve as an effective means to guide the identification of proteins predictive of pathological scarring.

The Free Deliveries and Caesarean Policy (FDCP) entitles all women in Morocco to deliver free of charge within public hospitals. This study assesses the policy's effectiveness by analysing household expenditures related to childbirth, by delivery type and quintile. Structured exit survey of 973 women in six provinces at five provincial hospitals, two regional hospitals, two university hospitals and three primary health centres with maternity units. Households reported spending a median of US$ 59 in total for costs inside and outside of hospitals. Women requiring caesareans payed more than women with uncomplicated deliveries (P < 0.0001). The median cost was US$45 for a uncomplicated delivery, US$50 for a complicated delivery and US$65 for a caesarean section. The prescription given upon exiting the hospital comprised 62% of the total costs. Eighty-eight per cent of women from the poorest quintiles faced catastrophic expenditures. The women's perception of their hospital stay and the FDCP policy was overwhelmingly positive, but differences were noted at the various sites. The policy has been largely but not fully effective in removing financial barriers for delivery care in Morocco. More progress should also be made on increasing awareness of the policy and on easing the financial burden, which is still borne by households with lower incomes. © 2015 John Wiley & Sons Ltd.

To analyze the trend of the monthly "caesarean section rate" (CSR) at the DISA V Lima-Ciudad Hospitals during the period 2001 - 2008. Ecological study that aim to analyze the monthly reports of all DISA V Lima-Ciudad Hospitals that attends childbirths, and by analyzing the trend of theirs monthly caesarean section ratio or monthly CSR (TCM = total caesarean births in a month * 100/total number of newborns in the same month ) to determine their characteristic patterns. Of the 7 hospitals studied, it was found that between 2001 and 2008, TCM average was 36.9% ± 9.1% (range: 16.5%-71.4%). From 2001 (33.5% ± 6.9%) to 2008 (39.7% ± 8.3%) years TCM increased 6.9% ± 7.0% on average, having registered a increase of 7.7% ± 6.4% at the year 2007 (43.5% ± 9.8%). Analyzing the TCM trend was found that most hospitals have a significant increase between 2004 and 2005 years. Analyzing the TCM trend was found that it tends to increase in April (37,9% ± 9,7%) and September (40.2% ± 8.9%), cycle that characterize most DISA V Lima-Ciudad Hospitals. TCM of the DISA V Lima-Ciudad Hospitals length exceeds the limit recommended by WHO and, during the period 2001-2008, has had a significant trend to increase.

Randomized controlled trials in wound care generalize poorly because they exclude patients with significant comorbid conditions. Research using real-world wound care patients is hindered by lack of validated methods to stratify patients according to severity of underlying illnesses. We developed a comprehensive stratification system for patients with wounds that predicts healing likelihood. Complete medical record data on 50,967 wounds from the United States Wound Registry were assigned a clear outcome (healed, amputated, etc.). Factors known to be associated with healing were evaluated using logistic regression models. Significant variables (p < 0.05) were determined and subsequently tested on a holdout sample of data. A different model predicted healing for each wound type. Some variables predicted significantly in nearly all models: wound size, wound age, number of wounds, evidence of bioburden, tissue type exposed (Wagner grade or stage), being nonambulatory, and requiring hospitalization during the course of care. Variables significant in some models included renal failure, renal transplant, malnutrition, autoimmune disease, and cardiovascular disease. All models validated well when applied to the holdout sample. The "Wound Healing Index" can validly predict likelihood of wound healing among real-world patients and can facilitate comparative effectiveness research to identify patients needing advanced therapeutics. © 2013 by the Wound Healing Society.

Early Induction of NRF2 Antioxidant Pathway by RHBDF2 Mediates Rapid Cutaneous Wound Healing

Rhomboid family protein RHBDF2, an upstream regulator of the epidermal growth factor (EGF) receptor signaling, has been implicated in cutaneous wound healing. However, the underlying molecular mechanisms are still emerging. In humans, a gain-of-function mutation in the RHBDF2 gene accelerates cutaneous wound healing in an EGFR-dependent manner. Likewise, a gain-of-function mutation in the mouse Rhbdf2 gene (Rhbdf2cub/cub) shows a regenerative phenotype (rapid ear-hole closure) resulting from constitutive activation of the EGFR pathway. Because the RHBDF2-regulated EGFR pathway is relevant to cutaneous wound healing in humans, we used Rhbdf2cub/cub mice to investigate the biological networks and pathways leading to accelerated ear-hole closure, with the goal of identifying therapeutic targets potentially effective in promoting wound healing in humans. Comparative transcriptome analysis of ear pinna tissue from Rhbdf2cub/cub and Rhbdf2+/+ mice at 0h, 15 min, 2h, and 24h post-wounding revealed an early induction of the nuclear factor E2-related factor 2 (NRF2)-mediated anti-oxidative pathway (0h and 15 min), followed by the integrin-receptor aggregation pathway (2h) as early-stage events immediately and shortly after wounding in Rhbdf2cub/cub mice. Additionally, we observed genes enriched for the Fc fragment of the IgG receptor IIIa (FCGR3A)-mediated phagocytosis pathway 24h post-wounding. Although cutaneous wound repair in healthy individuals is generally non-problematic, it can be severely impaired due to aging, diabetes, and chronic inflammation. This study suggests that activation of the NRF2-antioxidant pathway by rhomboid protein RHBDF2 might be beneficial in treating chronic non-healing wounds. PMID:28268192

To audit the quality of obstetric management preceding emergency caesarean sections for prolonged labour. A quality assurance analysis of a retrospective criterion-based audit supplemented by in-depth interviews with hospital staff. Two Tanzanian rural mission hospitals. Audit of 144 cases of women undergoing caesarean sections for prolonged labour; in addition, eight staff members were interviewed. Criteria of realistic best practice were established, and the case files were audited and compared with these. Hospital staff were interviewed about what they felt might be the causes for the audit findings. Prevalence of suboptimal management and themes emerging from an analysis of the transcripts. Suboptimal management was identified in most cases. Non-invasive interventions to potentially avoid operative delivery were inadequately used. When deciding on caesarean section, in 26% of the cases labour was not prolonged, and in 16% the membranes were still intact. Of the women with genuine prolonged labour, caesarean sections were performed with a fully dilated cervix in 36% of the cases. Vacuum extraction was not considered. Amongst the hospital staff interviewed, the awareness of evidence-based guidelines was poor. Word of mouth, personal experience, and fear, especially of HIV transmission, influenced management decisions. The lack of use and awareness of evidence-based guidelines led to misinterpretation of clinical signs, fear of simple interventions, and an excessive rate of emergency caesarean sections. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

The Hanikoda Method: 3-layered Negative Pressure Wound Therapy in Wound Bed Preparation.

Negative pressure wound therapy is a widely used method of wound dressing with various commercially available brands. The authors created the Hanikoda Method (HM) for effective wound bed preparation or definite wound closure. In this case series, the authors discuss 8 different wound cases that presented to their Plastics Unit from January 2014 to June 2015. Patients with traumatic or infected wounds were selected for treatment with the HM. Selected patients underwent multiple cycles of this method until their wounds were ready for definite wound closure or the wounds had closed by secondary closure. The purpose of any wound dressing is to encourage epithelization while ensuring no factors impede wound healing. An additional benefit is to reduce wound bed size so that it may close by secondary intention or require less skin graft coverage. Each layer of the dressing is described, along with its function in wound bed preparation or in closure. The HM facilitates reduction of wound size, wound bed preparation, and overall management.

CICATRIZATION OF WOUNDS

1. A method for measuring the area of a wound not geometric in form is described. 2. The rate of cicatrization of a wound is greater at the beginning than at the end of the period of repair. It depends on the area rather than on the age of the wound. There is a constant relation between the size of a wound and the rate of cicatrization. The larger the wound the greater is the rate of cicatrization. Two wounds of different size have a tendency to become equal. 3. The rate is proportional to the area, but diminishes less rapidly than the area. 4. The process of contraction is the more important factor in the repair of a wound. Epidermization completes the work of contraction. After the wound is healed, the cicatrix as a rule expands. 5. The curve representing the diminution of the size of an aseptic wound while it cicatrizes is regular and geometric. PMID:19868052

Dual therapeutic functions of F-5 fragment in burn wounds: preventing wound progression and promoting wound healing in pigs

Burn injuries are a leading cause of morbidity including prolonged hospitalization, disfigurement, and disability. Currently there is no Food and Drug Administration-approved burn therapeutics. A clinical distinction of burn injuries from other acute wounds is the event of the so-called secondary burn wound progression within the first week of the injury, in which a burn expands horizontally and vertically from its initial boundary to a larger area. Therefore, an effective therapeutics for burns should show dual abilities to prevent the burn wound progression and thereafter promote burn wound healing. Herein we report that topically applied F-5 fragment of heat shock protein-90α is a dual functional agent to promote burn wound healing in pigs. First, F-5 prevents burn wound progression by protecting the surrounding cells from undergoing heat-induced caspase 3 activation and apoptosis with increased Akt activation. Accordingly, F-5–treated burn and excision wounds show a marked decline in inflammation. Thereafter, F-5 accelerates burn wound healing by stimulating the keratinocyte migration-led reepithelialization, leading to wound closure. This study addresses a topical agent that is capable of preventing burn wound progression and accelerating burn wound healing. PMID:27382602

To perform, from an insurance perspective, a cost analysis of one of the outpatient community wound care clinics in the Netherlands, the Knowledge Centre in Wound Care (KCWC) at Venray. This study involved a cost analysis based on an observational cohort study with a one-year pre-admission and a one-year post-admission comparison of costs. Patients were included when they first consulted the outpatient wound care clinic. Participants were all insured by the same health insurance company, Coöperatie Volksgezondheidszorg (VGZ). A standard six-step procedure for performing cost studies was used to calculate the costs. Given the skewed cost data, non-parametric bootstrapping was used to test for statistical differences. There were 172 patients included in this study. The difference in costs related to wound care between the year before and the year after initial admission to the wound clinic amounted to an average reduction of €2621 (£1873) per patient in the base case analysis. The categories 'general practitioner', 'hospital care', 'mental health care' and 'transport' scored lower, indicating lower costs, in the year after admission to the wound clinic. In this study, only the reimbursement data of patients of one health insurance company, and specifically only those made under the 2006 Dutch Health Insurance Act, were available. Because of the observational design, definitive conclusions cannot be made regarding a demonstrated reduction of costs in the year post admission. Nevertheless, this study is a first attempt of a cost analysis of an equipped outpatient wound clinic as an innovative way of responding to the increasing number of chronic wounds in the Netherlands. The calculations show that savings in wound care are possible. A possible conflict of interest should be mentioned. First author AALM Rondas, PhD student at Maastricht University, is working at the KCWC wound clinic at Venray in the Netherlands as a physician. However, the research data were

The care of wounds in exotic animal species can be a challenging endeavor. Special considerations must be made in regard to the animal's temperament and behavior, unique anatomy and small size, and tendency toward secondary stress-related health problems. It is important to assess the entire patient with adequate systemic evaluation and consideration of proper nutrition and husbandry, which could ultimately affect wound healing. This article summarizes the general phases of wound healing, factors that affect healing, and principles of wound management. Emphasis is placed on novel methods of treating wounds and species differences in wound management and healing. Copyright © 2016 Elsevier Inc. All rights reserved.

An Examination of Women Experiencing Obstetric Complications Requiring Emergency Care: Perceptions and Sociocultural Consequences of Caesarean Sections in Bangladesh

Little is known about the physical and socioeconomic postpartum consequences of women who experience obstetric complications and require emergency obstetric care (EmOC), particularly in resource-poor countries such as Bangladesh where historically there has been a strong cultural preference for births at home. Recent increases in the use of skilled birth attendants show socioeconomic disparities in access to emergency obstetric services, highlighting the need to examine birthing preparation and perceptions of EmOC, including caesarean sections. Twenty women who delivered at a hospital and were identified by physicians as having severe obstetric complications during delivery or immediately thereafter were selected to participate in this qualitative study. Purposive sampling was used for selecting the women. The study was carried out in Matlab, Bangladesh, during March 2008–August 2009. Data-collection methods included in-depth interviews with women and, whenever possible, their family members. The results showed that the women were poorly informed before delivery about pregnancy-related complications and medical indications for emergency care. Barriers to care-seeking at emergency obstetric facilities and acceptance of lifesaving care were related to apprehensions about the physical consequences and social stigma, resulting from hospital procedures and financial concerns. The respondents held many misconceptions about caesarean sections and distrust regarding the reason for recommending the procedure by the healthcare providers. Women who had caesarean sections incurred high costs that led to economic burdens on family members, and the blame was attributed to the woman. The postpartum health consequences reported by the women were generally left untreated. The data underscore the importance of educating women and their families about pregnancy-related complications and preparing families for the possibility of caesarean section. At the same time, the health

Developing novel anti-fibrotic therapeutics to modulate post-surgical wound healing in glaucoma: big potential for small molecules

Ocular fibrosis leads to significant visual impairment and blindness in millions of people worldwide, and is one of the largest areas of unmet need in clinical ophthalmology. The antimetabolites, mitomycin C and 5-fluorouracil, are the current gold standards used primarily to prevent fibrosis after glaucoma surgery, but have potentially blinding complications like tissue damage, breakdown and infection. This review thus focuses on the development of new classes of small molecule therapeutics to prevent post-surgical fibrosis in the eye, especially in the context of glaucoma filtration surgery. We discuss recent advances and innovations in ophthalmic wound healing research, including antibodies, RNAi, gene therapy, nanoparticles, liposomes, dendrimers, proteoglycans and small molecule inhibitors. We also review the challenges involved in terms of drug delivery, duration of action and potential toxicity of new anti-fibrotic agents in the eye. PMID:25983855

Maternal obesity, obstetric interventions and post-partum anaemia increase the risk of post-partum sepsis: a population-based cohort study based on Swedish medical health registers.

The objective was to estimate whether maternal obesity and/or obstetric interventions are associated with diagnosed maternal post-partum sepsis. A retrospective observational cohort study including all deliveries in Sweden between 1997 and 2012 (N = 1,558,752). Cases of sepsis (n = 376) were identified by International Classification of Diseases, (ICD-10) codes A40, A41 and O 85 in the Medical Birth Register and the National Patient Register. The reference population was non-infected, and therefore, women with any other infection diagnosis and/or with dispensed antibiotics within eight weeks post-partum were excluded. Information on dispensed drugs was available in the prescribed drug Register. Women with sepsis were compared with non-infected women concerning maternal characteristics and obstetric interventions. Adjusted odds ratios (aOR) were determined using the Mantel-Haenszel technique. Adjustments were made for maternal age, parity and smoking. Obese women (body mass index ≥30) had a doubled risk of sepsis (3.6/10,000) compared with normal weight women (2.0/10,000) (aOR 1.85 (95%CI: 1.37-2.48)). Induction of labour (aOR 1.44 (95%CI: 1.09-1.91)), caesarean section overall (aOR 3.06 (95%CI: 2.49-3.77)) and elective caesarean section (aOR 2.41 (95%CI: 1.68-3.45)) increased the risk of sepsis compared with normal vaginal delivery. Post-partum anaemia due to acute blood loss was associated with maternal sepsis (aOR 3.40 (95%CI: 2.59-4.47)). Maternal obesity, obstetric interventions and post-partum anaemia due to acute blood loss increased the risk of diagnosed post-partum sepsis indicating that interventions in obstetric care should be considered carefully and anaemia should be treated if resources are available.

This is a clinical review of current techniques in wound bed preparation found to be effective in assisting the wound-healing process. The process begins with the identification of a correct diagnosis of the wound's etiology and continues with optimizing the patient's medical condition, including blood flow to the wound site. Débridement as the basis of most wound-healing strategies is then emphasized. Various débridement techniques, including surgery, topical agents, and biosurgery, are thoroughly discussed and illustrated. Wound dressings, including the use of negative pressure wound therapy, are then reviewed. To properly determine the timing of advance therapeutic intervention, the wound-healing progress needs to be monitored carefully with weekly measurements. A reduction in wound area of 10 to 15 percent per week represents normal healing and does not mandate a change in the current wound-healing strategy. However, if this level of wound area reduction is not met consistently on a weekly basis, then alternative healing interventions should be considered. There is a growing body of evidence that can provide guidance on the appropriate use of such adjuvants in the problem wound. Several adjuvants are discussed, including growth factor, bioengineered tissues, and hyperbaric medicine.

Protocol for a randomised controlled trial of fetal scalp blood lactate measurement to reduce caesarean sections during labour: the Flamingo trial [ACTRN12611000172909].

The rate of caesarean sections around the world is rising each year, reaching epidemic proportions. Although many caesarean sections are performed for concerns about fetal welfare on the basis of abnormal cardiotocography, the majority of babies are shown to be well at birth, meaning that the operation, with its inherent short and long term risks, could have been avoided without compromising the baby's health. Previously, fetal scalp blood sampling for pH estimation was performed in the context of an abnormal cardiotocograph, to improve the identification of babies in need of expedited delivery. This test has largely been replaced by lactate measurement, although its validity is yet to be established through a randomised controlled trial. This study aims to test the hypothesis that the performance of fetal scalp blood lactate measurement for women in labour with an abnormal cardiotocograph will reduce the rate of birth by caesarean section from 38 % to 25 % (a 35 % relative reduction). Prospective unblinded randomised controlled trial conducted at a single tertiary perinatal centre. Women labouring with a singleton fetus in cephalic presentation at 37 or more weeks' gestation with ruptured membranes and with an abnormal cardiotocograph will be eligible. Participants will be randomised to one of two groups: fetal monitoring by cardiotocography alone, or cardiotocography augmented by fetal scalp blood lactate analysis. Decisions regarding the timing and mode of delivery will be made by the treating team, in accordance with hospital protocols. The primary study endpoint is caesarean section with secondary outcomes collected from maternal, fetal and neonatal clinical course and morbidities. A cost effectiveness analysis will also be performed. A sample size of 600 will provide 90 % power to detect the hypothesised difference in the proportion of women who give birth by caesarean section. This world-first trial is adequately powered to determine the impact of fetal

With the growing demand for more efficient wound care after surgery, there is a necessity to develop a machine learning based image analysis approach to reduce the burden for health care professionals. The aim of this study was to propose a novel approach to recognize wound infection on the postsurgical site. Firstly, we proposed an optimal clustering method based on unimodal-rosin threshold algorithm to extract the feature points from a potential wound area into clusters for regions of interest (ROI). Each ROI was regarded as a suture site of the wound area. The automatic infection interpretation based on the support vector machine is available to assist physicians doing decision-making in clinical practice. According to clinical physicians' judgment criteria and the international guidelines for wound infection interpretation, we defined infection detector modules as the following: (1) Swelling Detector, (2) Blood Region Detector, (3) Infected Detector, and (4) Tissue Necrosis Detector. To validate the capability of the proposed system, a retrospective study using the confirmation wound pictures that were used for diagnosis by surgical physicians as the gold standard was conducted to verify the classification models. Currently, through cross validation of 42 wound images, our classifiers achieved 95.23% accuracy, 93.33% sensitivity, 100% specificity, and 100% positive predictive value. We believe this ability could help medical practitioners in decision making in clinical practice.

Why do niches develop in Caesarean uterine scars? Hypotheses on the aetiology of niche development

Caesarean section (CS) results in the occurrence of the phenomenon ‘niche’. A ‘niche’ describes the presence of a hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site of a previous CS. Using gel or saline instillation sonohysterography, a niche is identified in the scar in more than half of the women who had had a CS, most with the uterus closed in one single layer, without closure of the peritoneum. An incompletely healed scar is a long-term complication of the CS and is associated with more gynaecological symptoms than is commonly acknowledged. Approximately 30% of women with a niche report spotting at 6–12 months after their CS. Other reported symptoms in women with a niche are dysmenorrhoea, chronic pelvic pain and dyspareunia. Given the association between a niche and gynaecological symptoms, obstetric complications and potentially with subfertility, it is important to elucidate the aetiology of niche development after CS in order to develop preventive strategies. Based on current published data and our observations during sonographic, hysteroscopic and laparoscopic evaluations of niches we postulate some hypotheses on niche development. Possible factors that could play a role in niche development include a very low incision through cervical tissue, inadequate suturing technique during closure of the uterine scar, surgical interventions that increase adhesion formation or patient-related factors that impair wound healing or increase inflammation or adhesion formation.

The effects of place of birth on birth outcomes have been examined in several studies both locally and internationally. However, none has examined the impact on caesarean section rates of different level maternity hospitals operating within the one health service. This study aimed to examine the impact of place of (Hospital level 6; 4-5 or 4) on birth outcomes in a large metropolitan health service in Victoria. A cross-sectional study utilising data on births to low-risk first-time mothers during 2010-2011. Data were obtained from the Birthing Outcome System (BOS) database of Monash Health. Unadjusted and adjusted analyses were undertaken using logistic regression to examine the association between place of birth and caesarean section. In this group of low-risk nulliparae, there was evidence of a significant association between place of birth and caesarean section. The lower the acuity of the hospital, the higher the odds for the caesarean section. Compared with the level 6 hospital, the AdjOR for caesarean section at the level 4 hospital was 1.81 (95% CI: 1.37-2.41) and at the level 4-5 hospital, 1.30 (95% CI: 1.0-1.7). Low-risk nulliparae in spontaneous labour giving birth at the level 4 hospital in this health service are at significantly increased risk of caesarean section. This may have implications for the organisation and resource management of other level 4 public maternity units. Care in a tertiary (level 6) service may not necessarily equate to the higher rates of intervention reported by others. © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

This study investigated the effect of low-intensity laser irradiation (LILI) on pro-inflammatory cytokines involved in wound healing processes in diabetes and hypoxia. Diabetes is associated with impaired wound healing and a prolonged inflammatory phase. Pro-inflammatory cytokines such as interleukin (IL)-1β, tumor necrosis factor (TNF)-α and IL-6 are elevated in diabetes. LILI has been reported to accelerate wound healing and decrease inflammatory cytokines. A human skin fibroblast cell line (WS1) was used in vitro. Cells were exposed to various insults, namely, wounding, and a diabetic or hypoxic environment. Experimental cells were exposed to an energy density of 5  J/cm(2) using a continuous wave 636-nm diode laser at an average power of 95  mW, an illuminated area of 9.05  cm(2), and an irradiance of 11 mW/cm(2) (irradiation time, 476  sec). The effect of laser irradiation on cytokine expression was examined at 1 or 24  h post-irradiation. Cellular morphology, viability, proliferation, and cytokine expression (IL-1β, IL-6, and TNF-α) were investigated. Translocation of nuclear factor-kappa B (NF-κB) was also determined. There was a higher rate of migration in irradiated wounded cultures, and irradiated hypoxic cells showed an improvement in cellular morphology. All cell models showed an increase in proliferation. Normal wounded cells showed a decrease in apoptosis, TNF-α, and IL-1β. Diabetic wounded cells showed an increase in viability and a decrease in apoptosis and IL-1β, whereas hypoxic cells showed an increase in viability and IL-6, and a decrease in apoptosis and TNF-α. NF-κB was translocated into the nucleus post-irradiation. Phototherapy resulted in hastened wound closure, increased proliferation, and normalization of cellular function. The decrease in the different pro-inflammatory cytokines and NF-κB translocation was model and time dependent. Overall, laser irradiation resulted in a reduction in inflammatory cytokines and

Healthy individuals rarely have problems with wound healing. Most skin lesions heal rapidly and efficiently within one to two weeks. However, many medical and surgical complications can be attributed to deficiencies in wound repair. Open wounds have lost the barrier that protects tissues from bacterial invasion and allows the escape of vital fluids. Without expeditious healing, infections become more frequent. The CD24 gene encodes a heavily-glycosylated cell surface protein anchored to the membrane by phosphatidylinositol. CD24 plays an important role in the adaptive immune response and controls an important genetic checkpoint for homeostasis and autoimmune diseases in both mice and humans. We have previously shown that overexpression of CD24 results in increased proliferation and migration rates. To examine the role of CD24 in the wound healing process. An excisional model of wound healing was used and delayed wound healing was studied in genetically modified heat stable antigen (HSA/CD24)-deficient mice (HSA-/-) compared to wild-type (WT) mice. Large full-thickness skin wounds, excised on the back of mice, exhibited a significant delay in the formation of granulation tissue, and in wound closure when compared to their WTHSA+/+ littermates. Wounds were histologically analyzed and scored, based on the degree of cellular invasion, granulation tissue formation, vascularity, and re-epithelialization. Additionally, in stitched wounds, the HSA-/- mice failed to maintain their stitches; they did not hold and fell already 24 hours, revealing erythematous wound fields. Re-expression of HSA, delivered by lentivirus, restored the normal healing phenotype, within 24 hours post-injury, and even improved the healing in WT, and in BalbC mice. Delayed wound-healing in the absence of HSA/CD24 suggests that CD24 plays an important role in this process. Increased expression of CD24, even in the normal state, may be used to enhance wound repair.

Temporary Rectal Stenting for Management of Severe Perineal Wounds in Two Dogs.

PubMed

Skinner, Owen T; Cuddy, Laura C; Coisman, James G; Covey, Jennifer L; Ellison, Gary W

Perineal wounds in dogs present a challenge due to limited local availability of skin for closure and constant exposure to fecal contaminants. This report describes temporary rectal stenting in two dogs following severe perineal wounds. Dog 1 presented with a 4 × 4 cm full-thickness perineal slough secondary to multiple rectal perforations. A 12 mm internal diameter endotracheal tube was placed per-rectum as a temporary stent to minimize fecal contamination. The stent was removed 18 days after placement, and the perineal wound had healed at 32 days post-stent placement, when a minor rectal stricture associated with mild, intermittent tenesmus was detected. Long-term outcome was deemed good. Dog 2 presented with multiple necrotic wounds with myiasis, circumferentially surrounding the anus and extending along the tail. A 14 mm internal diameter endotracheal tube was placed per-rectum. The perineal and tail wounds were managed with surgical debridement and wet-to-dry and honey dressings prior to caudectomy and negative pressure wound therapy (NPWT). Delayed secondary wound closure and stent removal were performed on day six without complication. Long-term outcome was deemed excellent. Temporary rectal stenting may be a useful technique for fecal diversion to facilitate resolution of complex perineal injuries, including rectal perforation.

Enamel matrix proteins (EMPs) play a role in enamel formation and the development of the periodontium. Sporadic clinical observations of periodontal regeneration treatments with enamel matrix derivative (EMD), a commercial formulation of EMPs, suggest that it also promotes post-surgical healing of soft tissues. In vitro studies showed that EMD stimulates various cellular effects, which could potentially enhance wound healing. This study examines the in vivo effects of EMD on healing of an oral mucosa surgical wound in rats. A bilateral oral mucosa wound was created via a crestal incision in the anterior edentulous maxilla of Sprague-Dawley rats. Full-thickness flaps were raised, and, after suturing, EMD was injected underneath the soft tissues on one side, whereas the EMD vehicle was injected in the contralateral side. Animals were sacrificed after 5 or 9 days, and the wound area was subjected to histologic and immunohistochemical analysis of the epithelial gap, number of macrophages, blood vessels, proliferating cells, and collagen content in the connective tissue (CT). Gene expression analysis was also conducted 2 days post-surgery. EMD had no effect on the epithelial gap of the wound. On both days 5 and 9, EMD treatment increased significantly the number of blood vessels and the collagen content. EMD also enhanced (by 20% to 40%) the expression of transforming growth factors β1 and β2, vascular endothelial growth factor, interleukin-1β, matrix metalloproteinase-1, versican, and fibronectin. EMD improves oral mucosa incisional wound healing by promoting formation of blood vessels and collagen fibers in CT.

Successful wound care involves optimizing patient local and systemic conditions in conjunction with an ideal wound healing environment. Many different products have been developed to influence this wound environment to provide a pathogen-free, protected, and moist area for healing to occur. Newer products are currently being used to replace or augment various substrates in the wound healing cascade. This review of the current state of the art in wound-healing products looks at the latest applications of silver in microbial prophylaxis and treatment, including issues involving resistance and side effects, the latest uses of negative pressure wound devices, advanced dressings and skin substitutes, biologic wound products including growth factor applications, and hyperbaric oxygen as an adjunct in wound healing. With the abundance of available products, the goal is to find the most appropriate modality or combination of modalities to optimize healing. PMID:22567251

Oxidative damage to cornea can be induced by alkaline chemical burn which may cause vision loss or blindness. Recent studies showed that exogenous application of natural antioxidants may be a potential treatment for corneal wound healing. However, low ocular bioavailability and short residence time are the limiting factors of topically administered antioxidants. Ferulic acid (FA) is a natural phenolic compound and an excellent antioxidant. The study was aimed to investigate the effects of FA in corneal epithelial cells (CECs) under oxidative stress and evaluate the feasibility of use the thermosensitive chitosan-based hydrogel containing FA for corneal wound healing. The results demonstrated that post-treatment of FA on CECs could decrease the inflammation-level and apoptosis. In the rabbit corneal alkali burn model, post-treatment FA-loaded hydrogel may promote the corneal wound healing. The results of study suggest that FA-loaded hydrogel may have the potential applications in treating corneal alkali burn. Copyright © 2015 Elsevier Ltd. All rights reserved.

C. elegans epidermal wounding induces a mitochondrial ROS burst that promotes wound repair

PubMed Central

Xu, Suhong; Chisholm, Andrew D.

2014-01-01

SUMMARY Reactive oxygen species (ROS) such as hydrogen peroxide are generated at wound sites and act as long-range signals in wound healing. The roles of other ROS in wound repair are little explored. Here we reveal a cytoprotective role for mitochondrial ROS (mtROS) in C. elegans skin wound healing. We show that skin wounding causes local production of mtROS superoxide at the wound site. Inhibition of mtROS levels by mitochondrial superoxide-specific antioxidants blocks actin-based wound closure, whereas elevation of mtROS promotes wound closure and enhances survival of mutant animals defective in wound healing. mtROS act downstream of wound-triggered Ca2+ influx. We find that the Mitochondrial Calcium Uniporter MCU-1 is essential for rapid mitochondrial Ca2+ uptake and mtROS production after wounding. mtROS can promote wound closure by local inhibition of Rho GTPase activity via a redox-sensitive motif. These findings delineate a pathway acting via mtROS that promotes cytoskeletal responses in wound healing. PMID:25313960

Synopsis The care of wounds in exotic animal species can be a challenging endeavor. Special considerations must be made in regards to the animal’s temperament and behavior, unique anatomy and small size, and tendency towards secondary stress-related health problems. It is important to assess the entire patient with adequate systemic evaluation and consideration of proper nutrition and husbandry, which could ultimately impact wound healing. This article summarizes the general phases of wound healing, factors that impact healing, and principles of wound management. Emphasis is placed on novel methods of treating wounds and species differences in wound management and healing. PMID:26611923

Malignant wounds (MWs) occur in 5-10% of all cancer patients. Malodor and exudation are the most common side effects. The aim was to determine the influence of honey-coated compared with silver-coated bandages on treatment of MWs. Patients were randomly selected to enter either group A (honey-coated bandages) or group B (silver-coated bandages). Parameters were the following: wound size, cleanliness, malodor, exudation, and wound pain. Digital photographs, visual analog scales (VAS), and wound morphology registration were used for measurement at baseline and following the 4-week intervention. Sixty-nine patients with MWs and advanced cancer, aged 47-90 (median 65.6), were included. No statistically significant difference was noted between the groups with respect to wound size, degree of cleanliness, exudation, malodor, and wound pain. There was a median decrease in wound size of 15 cm² and 8 cm² in group A and B, respectively (p = 0.63). Based on post-intervention pooled data from the groups, improvement was seen in 62% of the participants with respect to wound size and in 58% (n = 69) with respect to cleanliness. The VAS score for malodor (p = 0.007) and exudation (p < 0.0001) improved significantly post-intervention. Patients with reduced wound size had a median survival time of 387 days compared with 134 days in patients with no wound reduction (p = 0.003). The use of honey-coated and silver-coated bandages improved the outcome of MWs. No differences were found between the two regimens. Both types of bandages are recommended for use by patients with MWs containing tumor debris and necrosis. 2011 by the Wound Healing Society.

Elective caesarean section versus vaginal delivery. Whither the end of traditional obstetrics?

PubMed

Husslein, P

2001-11-01

No other topic has dominated the obstetrical discussion to the same extent as caesarean section. Nor has any other aspect of obstetrics been subject to a comparable degree of professional controversy,quite recently the topic has been discussed in this journal by Ludwig and Loeffler. For some caesarean section remains a major surgical procedure with a corresponding level of risk, which must only be employed in the presence of specific complications and in conjunction with a clearly defined set of indications; others consider caesarean section quite simply to be the most efficient and straightforward means to deliver as well as the one attended by the least amount of risk. Opinion among those most immediately affected is likewise divided: For many women the experience of vaginal birth is among the most fulfilling of their entire life - comparable only to sexuality-related moments of ecstasy - other women come to regard birth as the worst thing that ever happened to them an experience attended by pain, fear, loneliness, perhaps even long lasting negative consequences. There can be no doubt that, this question also affects the foundations of patriarchal thinking, still so firmly embedded in peoples' minds: Are doctors to determine what exactly takes place in the delivery room and in the operating theatre, or will the patient - in obstetrics, the parturient - be enabled to assert her right to self-determination also in the medical context; especially in light of the fact that said right can currently be exercised in an almost unlimited fashion throughout the rest of one's adult life? It is against the wider background of this ongoing controversy that the ensuing article will seek to defuse the emotional charge characterising some of the commonly employed arguments and instead revert to a more rational and factually based approach to this question.

Androstenediol reduces the anti-inflammatory effects of restraint stress during wound healing.

PubMed

Head, Cynthia C; Farrow, Michael J; Sheridan, John F; Padgett, David A

2006-11-01

Restraint stress (RST) delays wound closure and suppresses pro-inflammatory gene expression by a glucocorticoid-dependent mechanism. Because androstenediol (AED) ameliorates many of the anti-inflammatory influences of glucocorticoids (GC) in vitro, it was hypothesized that treatment of stressed animals with AED would ameliorate the suppressive influence of restraint and restore healing to control levels. To test this hypothesis, male CD1 mice were subjected to nightly cycles of RST beginning 3 days prior to placement of two 3.5 mm full-thickness cutaneous wounds. To assess the influence of AED treatment on wound repair, mice were injected subcutaneously with 2.0 mg of AED or an equivalent volume of delivery vehicle (VEH) prior to wounding. The rate of wound closure was assessed daily by photoplanimetry. In addition, at 3, 6, 12, and 24 h post wounding, IL-1beta, MCP-1, and PDGF RNAs were quantified in wounds as a measure of inflammatory gene expression. The data showed that RST significantly delayed closure as compared to controls. In parallel, RST significantly decreased IL-1beta and PDGF gene expression as early as 12 h after wounding. In contrast, treatment with AED prevented the stress-induced delay in healing. Whereas wounds on VEH/RST mice did not achieve 50% closure until day 7, wounds on AED-treated animals, whether subjected to RST or not, had closed by 50% within 3 days of wounding. In addition, AED treatment prevented the stress-induced suppression of IL-1beta and PDGF gene expression 24 h after injury. Therefore, AED may provide a pharmacologic approach to ameliorate the anti-inflammatory effects of behavioral stress and in doing so, may improve tissue repair.

Negative Pressure Wound Therapy in the Management of Combat Wounds: A Critical Review

Maurya, Sanjay; Bhandari, Prem Singh

Significance: Wounds sustained in a combat trauma often result in a composite tissue loss. Combat injuries, due to high energy transfer to tissues, lead to trauma at multiple anatomical sites. An early wound cover is associated with lower rate of infections and a faster wound healing. The concept of negative pressure wound therapy (NPWT) in the management of combat-related wounds has evolved from the civilian trauma and the wounds from nontraumatic etiologies. Recent Advances: Encouraged by the results of NPWT in noncombat-related wounds, the military surgeons during Operation Iraqi Freedom and Operation Enduring Freedom used this novel method in a large percentage of combat wounds, with gratifying results. The mechanism of NPWT in wound healing is multifactorial and often complex reconstructive procedure can be avoided in a combat trauma setting. Critical Issues: Wounds sustained in military trauma are heavily contaminated with dirt, patient clothing, and frequently associated with extensive soft tissue loss and osseous destruction. Delay in evacuation during an ongoing conflict carries the risk of systemic infection. Early debridement is indicated followed by delayed closure of wounds. NPWT helps to provide temporary wound cover during the interim period of debridement and wound closure. Future Directions: Future area of research in combat wounds is related to abdominal trauma with loss of abdominal wall. The concept of negative pressure incisional management system in patients with a high risk of wound breakdown following surgery is under review, and may be of relevance in combat wounds.

Honey is a viscous, supersaturated sugar solution derived from nectar gathered and modified by the honeybee, Apis mellifera. Honey has been used since ancient times as a remedy in wound care. Evidence from animal studies and some trials has suggested that honey may accelerate wound healing. The objective was to determine whether honey increases the rate of healing in acute wounds (e.g. burns, lacerations) and chronic wounds (e.g. skin ulcers, infected surgical wounds). For this first update of the review we searched the Cochrane Wounds Group Specialised Register (searched 13 June 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 5); Ovid MEDLINE (2008 to May Week 5 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations 12 June 2012); Ovid EMBASE (2008 to 2012 Week 23); and EBSCO CINAHL (2008 to 8 June 2012). Randomised and quasi-randomised trials that evaluated honey as a treatment for any sort of acute or chronic wound were sought. There was no restriction in terms of source, date of publication or language. Wound healing was the primary endpoint. Data from eligible trials were extracted and summarised by one review author, using a data extraction sheet, and independently verified by a second review author. We identified 25 trials (with a total of 2987 participants) that met the inclusion criteria, including six new trials that were added to this update. In acute wounds, three trials evaluated the effect of honey in acute lacerations, abrasions or minor surgical wounds and 12 trials evaluated the effect of honey in burns. In chronic wounds, two trials evaluated the effect of honey in venous leg ulcers, and single trials investigated its effect in infected post-operative wounds, pressure injuries, cutaneous Lieshmaniasis, diabetic foot ulcers and Fournier's gangrene. Three trials recruited people into mixed groups of chronic or acute wounds. Most trials were at high or unclear risk of bias. In acute wounds

Although term breech presentation is a relatively rare condition (3-5% of all births), it continues to be an important indication for caesarean section and has contributed to its increased use. Risk of complications may be increased for both mother and foetus in such a situation. Vaginal delivery of a breech presenting foetus is complex and may involve many difficulties, so today there is a general consensus that planned caesarean section is better than planned vaginal birth for the foetus in breech presentation at term. External cephalic version is one of the most effective procedures in modern obstetrics. It involves the external manipulation of the foetus from the breech into the cephalic presentation. A successful manoeuvre can decrease costs by avoiding operative deliveries and decreasing maternal morbidity. The aim of the present study is to evaluate the effectiveness of this obstetric manoeuvre to increase the proportion of vertex presentation among foetuses that were formerly in the breech position near term, so as to reduce the caesarean section rate. The safety of the version is also showed. From 1999 to 2002, 89 women with foetal breech presentation underwent external cephalic version at the Department of Obstetrics and Gynaecology of the Brescia University. The gestational age was 36.8+/-0.8 weeks. The following variables have been taken into consideration: breech variety, placental location, foetal back position, parity, amount of amniotic fluid and gestational age. Every attempt was performed with a prior use of an intravenous drip of Ritodrine, and foetal heart rate was monitored continuously with cardiotocogram. The success rate of the procedure was 42.7% (n=38). No maternal or foetal complication or side effects occurred, both during and after the manoeuvre, except a transient foetal bradycardia that resolved spontaneously. Only one spontaneous reversion of the foetus occurred before delivery. Of all the women that underwent a successful version

Wound botulism is a rare infectious and toxicologic complication of trauma and i.v. drug abuse. Only 39 cases have been reported in detail in the English literature. This case report describes a patient with wound botulism who presented to four medical facilities before receiving definitive diagnosis and treatment. Although his history and physical examination were consistent with wound botulism, diagnosis and therapy were delayed because this rare disease was not considered initially in the differential diagnosis. Wound botulism should be considered in trauma patients and i.v. drug abusers who present with cranial nerve palsies and descending paresis.

Facial gunshot wound debridement: debridement of facial soft tissue gunshot wounds.

2013-01-01

Over the period 1981-1985 the author treated 1486 patients with facial gunshot wounds sustained in combat in Afghanistan. In the last quarter of 20th century, more powerful and destructive weapons such as M-16 rifles, AK-47 and Kalashnikov submachine guns, became available and a new approach to gunshot wound debridement is required. Modern surgeons have little experience in treatment of such wounds because of rare contact with similar pathology. This article is intended to explore modern wound debridement. The management of 502 isolated soft tissue injuries is presented. Existing principles recommend the sparing of damaged tissues. The author's experience was that tissue sparing lead to a high rate of complications (47.6%). Radical primary surgical debridement (RPSD) of wounds was then adopted with radical excision of necrotic non-viable wound margins containing infection to the point of active capillary bleeding and immediate primary wound closure. After radical debridement wound infection and breakdown decreased by a factor of 10. Plastic operations with local and remote soft tissue were made on 14, 7% of the wounded. Only 0.7% patients required discharge from the army due to facial muscle paralysis and/or facial skin impregnation with particles of gunpowder from mine explosions.

Bacterial infection is one of the major factors contributing to the compromised healing in chronic wounds. Sometimes bacteria biofilms formed on the wound are more resistant than adherent bacteria. Cold atmosphere plasma (CAP) has already shown its potential in contact-free disinfection, blood coagulation, and wound healing. In this study, we integrated a multimodal imaging system with a portable CAP device for image-guided treatment of infected wound in vivo and evaluated the antimicrobial effect on Pseudomonas aeruginosa sample in vitro.15 ICR mice were divided into three groups for therapeutic experiments:(1) control group with no infection nor treatment (2) infection group without treatment (3) infection group with treatment. For each mouse, a three millimeters punch biopsy was created on the dorsal skin. Infection was induced by Staphylococcus aureus inoculation one day post-wounding. The treated group was subjected to CAP for 2 min daily till day 13. For each group, five fixed wounds' oxygenation and blood perfusion were evaluated daily till day 13 by a multimodal imaging system that integrates a multispectral imaging module and a laser speckle imaging module. In the research of relationship between therapeutic depth and sterilization effect on P.aeruginosa in agarose, we found that the CAP-generated reactive species reached the depth of 26.7μm at 30s and 41.6μm at 60s for anti-bacterial effects. Image-guided CAP therapy can be potentially used to control infection and facilitate the healing process of infected wounds.

Caesarean section (CS) is often a life-saving procedure, but can also lead to serious complications, even more so in low-resource settings. Therefore unnecessary CS should be avoided and optimal circumstances for vaginal delivery should be created. In this study, we aim to audit indications for Caesarean sections and improve decision-making and obstetric management. Audit of all cases of CS performed from January to August 2013 was performed in a rural referral hospital in Tanzania. The study period was divided in three audit blocks; retrospective (before auditing), prospective 1 and prospective 2. A local audit panel (LP) and an external auditor (EA) judged if obstetric management was adequate and indications were appropriate or if CS could have been prevented and yet retain good pregnancy outcome. Furthermore, changes in modes of deliveries, overall pregnancy outcome and decision-to-delivery interval were monitored. During the study period there were 1868 deliveries. Of these, 403 (21.6%) were Caesarean sections. The proportions of unjustified CS prior to introduction of audit were as high as 34 and 75%, according to the respective judgments of LP and EA. Following introduction of audit, the proportions of unjustified CS decreased to 23% (p = 0.29) and 52% (p = 0.01) according to LP and EA respectively. However, CS rate did not change (20.2 to 21.7%), assisted vacuum delivery rate did not increase (3.9 to 1.8%) and median decision-to-delivery interval was 83 min (range 10 - 390 min). Although this is a single center study, these findings suggest that unnecessary Caesarean sections exist at an alarming rate even in referral hospitals and suggest that a vast number can be averted by introducing a focused CS audit system. Our findings indicate that CS audit is a useful tool and, if well implemented, can enhance rational use of resources, improve decision-making and harmonise practice among care providers.

Wound Healing Angiogenesis: Innovations and Challenges in Acute and Chronic Wound Healing

Background Formation of new blood vessels, by either angiogenesis or vasculogenesis, is critical for normal wound healing. Major processes in neovascularization include (i) growth-promoting or survival factors, (ii) proteolytic enzymes, (iii) activators of multiple differentiated and progenitor cell types, and (iv) permissible microenvironments. A central aim of wound healing research is to “convert” chronic, disease-impaired wounds into those that will heal. The problem Reduced ability to re-establish a blood supply to the injury site can ultimately lead to wound chronicity. Basic/Clinical Science Advances (1) Human fetal endothelial progenitor cells can stimulate wound revascularization and repair following injury, as demonstrated in a novel mouse model of diabetic ischemic healing. (2) Advances in bioengineering reveal exciting alternatives by which wound repair may be facilitated via the creation of vascularized microfluidic networks within organ constructs created ex vivo for wound implantation. (3) A “personalized” approach to regenerative medicine may be enabled by the identification of protein components present within individual wound beds, both chronic and acute. Clinical Care Relevance Despite the development of numerous therapies, impaired angiogenesis and wound chronicity remain significant healthcare problems. As such, innovations in enhancing wound revascularization would lead to significant advances in wound healing therapeutics and patient care. Conclusion Insights into endothelial progenitor cell biology together with developments in the field of tissue engineering and molecular diagnostics should not only further advance our understanding of the molecular mechanisms regulating wound repair but also offer innovative solutions to promote the healing of chronic and acute wounds in vivo.

Copaifera oleoresin is one of the most used natural products in popular medicine all over the world. Among other effects (i.e., anti-inflammatory, antinociceptive, microbicidal) one of the most well-known is its wound healing capacity. However, the mechanism by which the oleoresin presents its effect is still not clear. In this study, our aim was to evaluate the wound healing capacity of oleoresin obtained from Copaifera paupera, its mechanism of action and identify its major components. For these purposes, diabetic Swiss Webster mice were topically treated with oleoresin (100, 150 or 200 mg/kg) for 14 consecutive days after an excision was performed in the back of the mice. Cytokines, wound retraction and histological evaluation were conducted at 3, 7 and 10 days (for cytokines); 0, 3, 7, 10 and 14 days (for wound retraction); and 7 and 14 days (for histological evaluation). Our data indicate that oleoresin significantly reduced production of MCP-1 and TNF-α at days 7 and 10 post-excision and increased IL-10 production at both days. All treatments demonstrated an effect similar or higher to that in collagenase-treated mice. Histological evaluations demonstrated that higher dose treatment resulted in better resolution and closure of the wound and higher levels of collagen deposition and indexes of re-epithelialization even when compared with the collagenase-treated group. The treatment with oleoresin from Copaifera paupera demonstrated that it is even better than an ointment routinely used for improvement of wound healing, suggesting this oleoresin as an option for use in diabetic patients.

Copaifera oleoresin is one of the most used natural products in popular medicine all over the world. Among other effects (i.e., anti-inflammatory, antinociceptive, microbicidal) one of the most well-known is its wound healing capacity. However, the mechanism by which the oleoresin presents its effect is still not clear. In this study, our aim was to evaluate the wound healing capacity of oleoresin obtained from Copaifera paupera, its mechanism of action and identify its major components. For these purposes, diabetic Swiss Webster mice were topically treated with oleoresin (100, 150 or 200 mg/kg) for 14 consecutive days after an excision was performed in the back of the mice. Cytokines, wound retraction and histological evaluation were conducted at 3, 7 and 10 days (for cytokines); 0, 3, 7, 10 and 14 days (for wound retraction); and 7 and 14 days (for histological evaluation). Our data indicate that oleoresin significantly reduced production of MCP-1 and TNF-α at days 7 and 10 post-excision and increased IL-10 production at both days. All treatments demonstrated an effect similar or higher to that in collagenase-treated mice. Histological evaluations demonstrated that higher dose treatment resulted in better resolution and closure of the wound and higher levels of collagen deposition and indexes of re-epithelialization even when compared with the collagenase-treated group. The treatment with oleoresin from Copaifera paupera demonstrated that it is even better than an ointment routinely used for improvement of wound healing, suggesting this oleoresin as an option for use in diabetic patients.

Skin wounds are associated with significant morbidity and mortality. Data are, however, not readily available for benchmarking, to allow prognostic evaluation, and to suggest when involvement of wound-healing experts is indicated. We, therefore, conducted an observational cohort study to investigate wound healing and all-cause mortality associated with different types of skin wounds. Consecutive skin wound patients who received wound care by home-care nurses from January 2010 to December 2011 in a district in Eastern Denmark were included in this study. Patients were followed until wound healing, death, or the end of follow-up on December 2012. In total, 958 consecutive patients received wound care by home-care nurses, corresponding to a 1-year prevalence of 1.2% of the total population in the district. During the study, wound healing was achieved in 511 (53.3%), whereas 90 (9.4%) died. During the first 3 weeks of therapy, healing was most likely to occur in surgical wounds (surgical vs. other wounds: adjusted hazard ratio [AHR] 2.21, 95% confidence interval 1.50-3.23), while from 3 weeks to 3 months of therapy, cancer wounds, and pressure ulcers were least likely to heal (cancer vs. other wounds: AHR 0.12, 0.03-0.50; pressure vs. other wounds: AHR 0.44, 0.27-0.74). Cancer wounds and pressure ulcers were further associated with a three times increased probability of mortality compared with other wounds (cancer vs. other wounds: AHR 3.19, 1.35-7.50; pressure vs. other wounds: AHR 2.91, 1.56-5.42). In summary, the wound type was found to be a significant predictor of healing and mortality with cancer wounds and pressure ulcers being associated with poor prognosis. © 2015 by the Wound Healing Society.

It can be said that the occurrence and development of wounds, healing, delayed healing, and the notion of chronic wound are some of the basic characteristics of all living beings. When it comes to people, there are a number of processes that take place during wound healing, and even under ideal circumstances, they create a functionally less valuable skin tissue, along with structural and functional changes. Fibrosis in the form of hypertrophic scars and keloids, contractures and adhesions are examples of excessive healing. Microcirculation is significantly different from healthy skin circulation with consequential formation of local hypoxia and stagnation in lymph flow with edema. Poor functionality of the scar tissue, particularly in the areas exposed to stronger forces, can cause forming of wounds. Such wounds are hard to heal despite the inexistence of other possible reasons for delayed healing, precisely because of their poor functionality and placement. The presence of wound requiring long-term treatment affects all areas of patient life and leads to decline in the quality of life. Exemplified by case presentation of a patient with post-traumatic wound in the scar area, in our office we showed a model of care based on the principle of overall personalized care with the biopsychosocial approach. Diagnostic and therapeutic procedures included wound assessment, biofilm and lymphedema detection, assessment of the patient’s psychosocial status, risk factors for wound healing, vascular ultrasound diagnostics, carboxytherapy as specialized adjuvant therapy, use of modern wound dressings, and compression therapy. Supportive psychotherapy was conducted in positive communication environment during treatment. In this way, in an atmosphere of cooperation with the patient, it was possible not only to influence the process of wound healing as the primary objective, but also to improve the quality of the patient’s life, as well as to influence our professional

Near-miss maternal morbidity from severe haemorrhage at caesarean section: A process and structure audit of system deficiencies in South Africa.

A rising caesarean section rate and substandard peri-operative care are believed to be the main reasons for recent increases in maternal deaths from bleeding during and after caesarean section (BDACS) in South Africa (SA). The Donabedian model assumes that clinical outcomes are influenced by healthcare workers and the healthcare system. To evaluate near-miss cases from BDACS with regard to health system structure (resources and facilities) and process (patient care). A cross-sectional prospective study was conducted in greater Johannesburg, SA. Data of women who had near-miss-related BDACS were collected by means of ongoing surveillance at 13 public hospitals. The World Health Organization intervention criteria were used to identify near-miss cases. A comparison of structure and process between the healthcare facilities was conducted. Of 20 527 caesarean sections , there were 93 near misses and 7 maternal deaths from BDACS. Dominant risk factors for near misses were previous caesarean section (43.9%), anaemia (25.3%) and pregnancy-induced hypertension (28.6%). Eighteen women were transferred to higher levels of care, and 8 (44.4%) experienced transport delays of >1 hour. The caesarean section decision-to-incision interval (DII) was ≥60 minutes in 77 of 86 women, with an average interval of 4 hours. Structural deficiencies were frequently present in district hospitals, and there were serious delays in ambulance transfer and DIIs at all levels of care. The majority of the women had risk factors for BDACS. There were major ambulance delays and lack of facilities, mostly in district hospitals. All women required life-saving interventions, but could not access appropriate care timeously. Prevention and management of BDACS require a fully functional health system.

Variations exist in the surgical techniques used for caesarean section and many have not been rigorously assessed in randomised controlled trials. We aimed to assess whether any surgical techniques were associated with improved outcomes for women and babies. CORONIS was a pragmatic international 2×2×2×2×2 non-regular fractional, factorial, unmasked, randomised controlled trial that examined five elements of the caesarean section technique in intervention pairs. CORONIS was undertaken at 19 sites in Argentina, Chile, Ghana, India, Kenya, Pakistan, and Sudan. Each site was assigned to three of the five intervention pairs: blunt versus sharp abdominal entry; exteriorisation of the uterus for repair versus intra-abdominal repair; single-layer versus double-layer closure of the uterus; closure versus non-closure of the peritoneum (pelvic and parietal); and chromic catgut versus polyglactin-910 for uterine repair. Pregnant women were eligible if they were to undergo their first or second caesarean section through a planned transverse abdominal incision. Women were randomly assigned by a secure web-based number allocation system to one intervention from each of the three assigned pairs. All investigators, surgeons, and participants were unmasked to treatment allocation. The primary outcome was the composite of death, maternal infectious morbidity, further operative procedures, or blood transfusion (>1 unit) up to the 6-week follow-up visit. Women were analysed in the groups into which they were allocated. The CORONIS Trial is registered with Current Controlled Trials: ISRCTN31089967. Between May 20, 2007, and Dec 31, 2010, 15 935 women were recruited. There were no statistically significant differences within any of the intervention pairs for the primary outcome: blunt versus sharp entry risk ratio 1·03 (95% CI 0·91-1·17), exterior versus intra-abdominal repair 0·96 (0·84-1·08), single-layer versus double-layer closure 0·96 (0·85-1·08), closure versus non

Impaired wound healing, as it occurs in diabetes mellitus or long-term corticoid treatment, is commonly associated with disability, diminished quality of life, and high economic costs. Selective agonists of the A2A receptor subtype of adenosine, an endogenous regulator of inflammation, promote tissue repair in animal models, both healthy and with impaired healing. Plasmin-mediated proteolysis of fibrin and other matrix proteins is essential for cell migration at sites of injury. Since adenosine A2A receptor activation increases plasminogen activator release from macrophages and mast cells, we studied the effect of a selective agonist, CGS-21680, on full-thickness excisional wound closure in wild-type, urokinase plasminogen activator (uPA)-deficient, and tissue plasminogen activator (tPA)-deficient mice. Wound closure was impaired in tPA- and uPA-deficient mice as compared with wild-type mice, and topical application of CGS-21680 significantly increased the rate at which wounds closed in wild-type mice and uPA-deficient mice, but not in tPA-deficient mice. Immunostaining of tissue sections showed that tPA was present in endothelial cells and histiocytes by day 3 post-wound and also by day 6. In contrast, uPA was more prominent in these cell types only by day 6 post-wound. Our results confirm that plasminogen activation contributes to wound repair and are consistent with the hypothesis that adenosine A2A receptor activation promotes wound closure by a mechanism that depends upon tPA, but not uPA. Moreover, our results suggest that topical adenosine A2A receptor agonists may be useful in promotion of wound closure in patients with impaired wound healing.

Patient-initiated elective Caesarean section (PIECS) is increasingly prevalent and is emerging as an urgent issue for individual maternity practitioners, hospitals, and policy makers, as well as for maternity patients. This qualitative study sought to explore women's experiences of the decision-making process leading to elective operative delivery without medical indication. We conducted 17 exploratory qualitative in-depth interviews with primiparous women who had undergone a patient-initiated elective Caesarean section in the absence of any medical indication. The study took place in five hospitals (three urban, two semi-rural) in British Columbia. The findings revealed three themes within the process of women deciding to have a Caesarean section: the reasons for their decision, the qualities of the decision-making process, and the social context in which the decision was made. The factors that influenced a patient-initiated request for delivery by Caesarean section in participants in this study were diverse, culturally dependent, and reflective of varying degrees of emotional and evidence-based influences. PIECS is a rare but socially significant phenomenon. The a priori decision making of some women choosing PIECS does not follow the usual diagnosis-intervention trajectory, and the care provider may have to work in reverse to ensure that the patient fully understands the risks and benefits of her decision subsequent to the decision having been made, while still ensuring patient autonomy. Results from this study provide a context for a woman's request for an elective Caesarean section without medical indication, which may contribute to a more efficacious informed consent process.

Is first birth Caesarean delivery associated with a lower likelihood of subsequent childbearing when compared with first birth vaginal delivery? In this study of US women whose first delivery was in 2000, those who had a Caesarean delivery were less likely to have a subsequent live birth than those who delivered vaginally. Some studies have reported lower birth rates subsequent to Caesarean delivery in comparison with vaginal delivery, while other studies have reported no difference. We conducted a retrospective cohort study of 52 498 women who had a first singleton live birth in the State of Pennsylvania, USA in 2000 and were followed to the end of 2008 via Pennsylvania birth certificate records to identify subsequent live births during the 8- to 9-year follow-up period. Birth certificate records of first singleton births were linked to the hospital discharge data for each mother and newborn, and linked to all birth certificate records for each mother's subsequent deliveries which occurred in 2000 to the end of 2008. Poisson regression models were used to evaluate the association between first birth factors and whether or not there was a subsequent live birth during the follow-up period. Over an average of 8.5 years of follow-up, 40.2% of women with a Caesarean first birth did not have a subsequent live birth, compared with 33.1% of women with a vaginal first birth (risk ratio (RR): 1.21, 95% confidence interval (CI): 1.18-1.25). Adjustment for the demographic confounders of maternal age, race, education, marital status and health insurance coverage attenuated the RR to 1.16 (95% CI: 1.13-1.19). Specific pregnancy and childbirth-related complications associated with not having a subsequent live birth included diabetes-related disorders, abnormalities of organs and soft tissues of the pelvis, fetal abnormalities, premature or prolonged rupture of membranes, hypertensive disorders, amnionitis, fetal distress and other maternal health problems.

Wound moisture is known to be a key parameter to ensure optimum healing conditions in wound care. This study tests the moisture content of wounds in normal practice in order to observe the moisture condition of the wound at the point of dressing change. This study is also the first large-scale observational study that investigates wound moisture status at dressing change. The WoundSense sensor is a commercially available moisture sensor which sits directly on the wound in order to find the moisture status of the wound without disturbing or removing the dressing. The results show that of the 588 dressing changes recorded, 44·9% were made when the moisture reading was in the optimum moisture zone. Of the 30 patients recruited for this study, 11 patients had an optimum moisture reading for at least 50% of the measurements before dressing change. These results suggest that a large number of unnecessary dressing changes are being made. This is a significant finding of the study as it suggests that the protocols currently followed can be modified to allow fewer dressing changes and less disturbance of the healing wound bed. © 2015 The Authors.

To determine the effectiveness of implementing a clinical practice guideline (CPG) on antibiotic use for adults with fresh traumatic wounds who attended the trauma center at Siriraj Hospital, Bangkok. A prospective study of 600 adult patients who had fresh traumatic wounds (≤ 6 hours) was conducted at Siriraj Trauma Center from March 2013 to March 2014. The CPG was introduced to physicians, nurses and medical students by posting the CPG at the patient care areas of the trauma center. The outcomes were an appropriate classification of wounds according to the CPG recommendations, prevalence of antibiotic prescribing, incidence of wound infection and compliance with the CPG. Clean-contaminated wounds that did not need antibiotic treatment and clean-contaminated and contaminated wounds that required antibiotics were observed in 63.2, 6.7, and 30.1% ofthe patients, respectively. Antibiotics were given to 512 patients (85.3%). Infections occurred in six patients (1.0%). Antibiotic prescription according to CPG recommendations was observed for 243 patients (40.5%). The prevalence of antibiotic use in the CPG-compliant group (65.8%) was significantly less than that in the CPG-noncompliant group (98.6%) (p < 0.001). The patients in the CPG-compliant group had more contaminated wounds than those in the CPG-noncompliant group (51.4 vs. 15.7%, p < 0.001). The incidences of wound infection were very low in both groups and not significantly different (1.2 vs. 0.8%, p = 0.690). Antibiotic prophylaxis was necessary in less than 36.8% of adults with fresh traumatic wounds who attended Siriraj Trauma Center Compliance to CPG implementation using simple intervention seemed to be low. Adhering to CPG recommendations for antibiotic prophylaxis in adults with fresh traumatic wounds can reduce the unnecessary prescribing of antibiotics without increasing the rate of wound infection.

To illustrate the variability in the use of antibiotic prophylaxis for caesarean section, and its effect on the prevention of postoperative infections. Secondary analysis of a cross-sectional study. Twenty-nine countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health. Three hundred and fifty-nine health facilities with the capacity to perform caesarean section. Descriptive analysis and effect estimates using multilevel logistic regression. Coverage of antibiotic prophylaxis for caesarean section. A total of 89 121 caesarean sections were performed in 332 of the 359 facilities included in the survey; 87% under prophylactic antibiotic coverage. Thirty five facilities provided 0-49% coverage and 77 facilities provided 50-89% coverage. Institutional coverage of prophylactic antibiotics varied greatly within most countries, and was related to guideline use and the practice of clinical audits, but not to the size, location of the institution or development index of the country. Mothers with complications, such as HIV infection, anaemia, or pre-eclampsia/eclampsia, were more likely to receive antibiotic prophylaxis. At the same time, mothers undergoing caesarean birth prior to labour and those with indication for scheduled deliveries were also more likely to receive antibiotic prophylaxis, despite their lower risk of infection, compared with mothers undergoing emergency caesarean section. Coverage of antibiotic prophylaxis for caesarean birth may be related to the perception of the importance of guidelines and clinical audits in the facility. There may also be a tendency to use antibiotics when caesarean section has been scheduled and antibiotic prophylaxis is already included in the routine clinical protocol. This study may act as a signal to re-evaluate institutional practices as a way to identify areas where improvement is possible. © 2014 RCOG The World Health Organization retains copyright and all other rights in

Background Current wound assessment practices are lacking on several measures. For example, the most common method for measuring wound size is using a ruler, which has been demonstrated to be crude and inaccurate. An increase in periwound temperature is a classic sign of infection but skin temperature is not always measured during wound assessments. To address this, we have developed a smartphone application that enables non-contact wound surface area and temperature measurements. Here we evaluate the inter-rater reliability and accuracy of this novel point-of-care wound assessment tool. Methods and findings The wounds of 87 patients were measured using the Swift Wound app and a ruler. The skin surface temperature of 37 patients was also measured using an infrared FLIR™ camera integrated with the Swift Wound app and using the clinically accepted reference thermometer Exergen DermaTemp 1001. Accuracy measurements were determined by assessing differences in surface area measurements of 15 plastic wounds between a digital planimeter of known accuracy and the Swift Wound app. To evaluate the impact of training on the reproducibility of the Swift Wound app measurements, three novice raters with no wound care training, measured the length, width and area of 12 plastic model wounds using the app. High inter-rater reliabilities (ICC = 0.97–1.00) and high accuracies were obtained using the Swift Wound app across raters of different levels of training in wound care. The ruler method also yielded reliable wound measurements (ICC = 0.92–0.97), albeit lower than that of the Swift Wound app. Furthermore, there was no statistical difference between the temperature differences measured using the infrared camera and the clinically tested reference thermometer. Conclusions The Swift Wound app provides highly reliable and accurate wound measurements. The FLIR™ infrared camera integrated into the Swift Wound app provides skin temperature readings equivalent to the clinically

Chronic wounds such as diabetic foot wounds are a tremendous burden to the health care system and often require a multidisciplinary approach to prevent amputations. Advanced technologies such as negative pressure wound therapy (NPWT) and bioengineered tissues have been successfully used in the treatment of these types of complex wounds. However, the introduction of NPWT with instillation (NPWTi) has provided an alternative treatment for treating complex and difficult-to-heal wounds. This article provides an overview of NPWT and the new NPWTi system and describes preliminary experience using NPWTi on patients with complicated infected diabetic foot wounds after surgical debridement and in a multidisciplinary setting. © 2013 The Author.

Individual differences of mink, including color type, are speculated to affect the course of wound healing, thereby impacting wound assessment and management on the farms, as well as the assessment of wounds in forensic cases. In this study, we examined the effect of color type on early wound healing in farmed mink. Full thickness excisional wounds (2 × 2 cm) were made on the back in 18 mink of the color types Brown, Silverblue and Blue Iris. Gross and microscopic pathology of the wounds was evaluated 2 days post-wounding together with degree of wound size reduction, presence of bacteria and blood analyses. Pathological examination on day 2 showed the greatest mean wound size reduction in Brown mink (11.0%) followed by Blue Iris (7.9%) and Silverblue (1.6%). Bacteria were cultured from all wounds, and predominantly Staphylococcus species were recovered in mixed or pure culture. Histopathology from day 2 wounds showed a scab overlying necrotic wound edges, which were separated from underlying vital tissue by a demarcation zone rich in polymorphonuclear leukocytes. Fibroblasts and plump endothelial cells were more numerous in the deeper tissues. Complete blood count parameters were within normal ranges in most cases, however, the mink showed mildly to markedly decreased hematocrit and six mink of the color types Silverblue and Blue Iris showed moderately elevated numbers of circulating segmented neutrophils on day 2. There was a marked increase in concentration of serum amyloid A from day 0 to day 2 in all color types. We have described differences in early wound healing between mink of the color types Brown, Silverblue and Blue Iris by use of an experimental wound model in farmed mink. The most pronounced difference pertained to the degree of wound size reduction which was greatest in Brown mink, followed by Blue Iris and Silverblue, respectively.

Objective : The use of negative pressure wound therapy (NPWT) for post-surgical cardiothoracic, orthopedic, plastic, and obstetric and gynecologic procedures has been described. However, there are no data regarding its use for lower limb bypass incisions. We aimed to investigate the outcomes of NPWT in preventing surgical site infection (SSI) in patients with lower limb arterial bypass incisions. Materials and Methods : We retrospectively used data of 42 patients who underwent lower limb arterial bypass with reversed great saphenous vein between March 2014 and June 2016 and compared conventional wound therapy and NPWT with regard to preventing SSI. Results : Twenty-eight (67%) patients underwent conventional wound therapy and 14 (33%) underwent NPWT. There were no statistical differences regarding patient characteristics and mean SSI risk scores between the two patient groups (13.7% for conventional wound therapy vs. 13.4% for NPWT; P=0.831). In the conventional group, nine instances of SSI (32%) and three (11%) of these required subsequent surgical wound debridement, whereas in the NPWT group, there was no SSI incidence (P=0.019). Secondary outcomes such as the length of hospital stay, 30-day readmission rate, and need for secondary vascular procedures were not statistically different between the two groups. Conclusion : The use of NPWT for lower limb arterial bypass incisions is superior to that of conventional wound therapy because it may prevent SSIs.

Polysaccharides are the main macromolecules of Aloe vera gel but no data about their effect on extracellular matrix (ECM) elements are available. Here, mannose rich Aloe vera polysaccharides (AVP) with molecular weight between 50 and 250 kDa were isolated and characterized. Open cutaneous wounds on the back of 45 rats (control and treated) were daily treated with 25mg (n=15) and 50 mg (n=15) AVP for 30 days. The levels of MMP-3 and TIMP-2 gene expression were analyzed using real time PCR. The levels of n-acetyl glucosamine (NAGA), n-acetyl galactosamine (NAGLA) and collagen contents were also measured using standard biochemical methods. Faster wound closure was observed at day 15 post wounding in AVP treated animals in comparison with untreated group. At day 10 post wounding, AVP inhibited MMP-3 gene expression, while afterwards MMP-3 gene expression was upregulated. AVP enhanced TIMP-2 gene expression, collagen, NAGLA and NAGA synthesis in relation to untreated wounds. Our results suggest that AVP has positive effects on the regulation of ECM factor synthesis, which open up new perspectives for the wound repair activity of Aloe vera polysaccharide at molecular level.

Excisional surgical debridement (SD) is still the gold standard in the treatment of deeply burned hands, though the intricate anatomy is easily damaged. Previous studies demonstrated that enzymatic debridement with the bromelain debriding agent NexoBrid ® (EDNX) is more selective and thus can preserve viable tissue with excellent outcome results. So far no method paper has been published presenting different treatment algorithms in this new field. Therefore our aim was to close this gap by presenting our detailed learning curve in EDNX of deeply burned hands. We conducted a single-center prospective observational clinical trial treating 20 patients with deeply burned hands with EDNX. Different anaesthetic procedures, debridement and wound treatment algorithms were compared and main pitfalls described. EDNX was efficient in 90% of the treatments though correct wound bed evaluation was challenging and found unusual compared to SD. Post EDNX surprisingly the majority of the burn surface area was found overestimated (18 wounds). Finally we simplified our process and reduced treatment costs by following a modified treatment algorithm and treating under plexus anaesthesia bedside through a single nurse and one burn surgeon solely. Suprathel ® could be shown to be an appropriate dressing for wound treatment after EDNX. Complete healing (less 5% rest defect) was achieved at an average of day 28. EDNX in deep burned hands is promising regarding handling and duration of the treatment, efficiency and selectivity of debridement, healing potential and early rehabilitation. Following our treatment algorithm EDNX can be performed easily and even without special knowledge in burn wound depth evaluation. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

Background Healthy individuals rarely have problems with wound healing. Most skin lesions heal rapidly and efficiently within one to two weeks. However, many medical and surgical complications can be attributed to deficiencies in wound repair. Open wounds have lost the barrier that protects tissues from bacterial invasion and allows the escape of vital fluids. Without expeditious healing, infections become more frequent. The CD24 gene encodes a heavily-glycosylated cell surface protein anchored to the membrane by phosphatidylinositol. CD24 plays an important role in the adaptive immune response and controls an important genetic checkpoint for homeostasis and autoimmune diseases in both mice and humans. We have previously shown that overexpression of CD24 results in increased proliferation and migration rates. Aim To examine the role of CD24 in the wound healing process. Methods An excisional model of wound healing was used and delayed wound healing was studied in genetically modified heat stable antigen (HSA/CD24)-deficient mice (HSA -/-) compared to wild-type (WT) mice. Results Large full-thickness skin wounds, excised on the back of mice, exhibited a significant delay in the formation of granulation tissue, and in wound closure when compared to their WTHSA +/+ littermates. Wounds were histologically analyzed and scored, based on the degree of cellular invasion, granulation tissue formation, vascularity, and re-epithelialization. Additionally, in stitched wounds, the HSA -/- mice failed to maintain their stitches; they did not hold and fell already 24 hours, revealing erythematous wound fields. Re-expression of HSA, delivered by lentivirus, restored the normal healing phenotype, within 24 hours post-injury, and even improved the healing in WT, and in BalbC mice. Conclusions Delayed wound-healing in the absence of HSA/CD24 suggests that CD24 plays an important role in this process. Increased expression of CD24, even in the normal state, may be used to enhance wound

Our aim was to assess the effectiveness of hydro-responsive wound dressing (HRWD) in debridement and wound bed preparation of a variety of acute and chronic wounds that presented with devitalised tissue needing removal so that healing may proceed. This was a non-comparative evaluation of acute and chronic wounds that required debridement as part of their normal treatment regimen. Clinicians recorded wound changes including a subjective assessment level of devitalised tissue and wound bed preparation, presence of pain, wound status (e.g., wound size) and periwound skin condition. Data was also collected from clinicians and patients to provide information on clinical performance of the dressing. We recruited 100 patients with a variety of wound types into the study. Over 90% of the clinicians reported removal of devitalised tissue to enable a healing response in both chronic and acute wounds. Specifically, over the course of the evaluation period, levels of devitalised tissue (necrosis and slough) reduced from 85.5% to 26.3%, and this was accompanied by an increase in wound bed granulation from 12.0% to 33.7%. Correspondingly, there was a 40% reduction in wound area, hence a clinically relevant healing response was seen upon treatment with HRWD. It is also noteworthy that this patient population included a significant proportion of chronic wounds (51.4%) that showed no signs of wound progression within <4 weeks before study inclusion. Of these chronic wounds, 93% demonstrated wound progression upon treatment with HRWD. Despite reported pain levels being low pre- and post-dressing change, overall wound pain improved (reduced) in 48% of patients. Periwound skin condition showed a tendency towards improvement, and the fluid management capabilities of the HRWD was reported as good to excellent in the majority of cases. Wound infections were reduced by at least 60% over the evaluation period. A simple cost-effective analysis demonstrated significant savings using HRWD (�

Moist wound care has been established as standard therapy for chronic wounds with impaired healing. Healing in acute wounds, in particular in minor superficial acute wounds - which indeed are much more numerous than chronic wounds - is often taken for granted because it is assumed that in those wounds normal phases of wound healing should run per se without any problems. But minor wounds such as small cuts, scraps or abrasions also need proper care to prevent complications, in particular infections. Local wound care with minor wounds consists of thorough cleansing with potable tap water or normal saline followed by the application of an appropriate dressing corresponding to the principles of moist wound treatment. In the treatment of smaller superficial wounds, it appears advisable to limit the choice of dressing to just a few products that fulfil the principles of moist wound management and are easy to use. Hydroactive colloid gels combining the attributes of hydrocolloids and hydrogels thus being appropriate for dry and exuding wounds appear especially suitable for this purpose - although there is still a lack of data from systematic studies on the effectiveness of these preparations. © 2010 The Authors.

To demonstrate the relationship between the timing of opening of the uterine isthmus and bleeding during pregnancy and caesarean section in patients with placenta previa. A prospective observational study was conducted at a single perinatal centre. All patients with placenta previa, diagnosed between 20 and 22 weeks of gestation, who were followed up at the study hospital and underwent caesarean section were enrolled. The condition of the uterine isthmus was examined every 2 weeks. The timing (in gestational weeks) of complete opening of the uterine isthmus was determined. Patients were divided into two groups: patients in whom the uterine isthmus opened before 25 weeks of gestation (EO-previa), and patients in whom the uterine isthmus opened after 25 weeks of gestation (LO-previa). The frequency of bleeding during pregnancy and the amount of intra-operative bleeding were compared between the two groups. Forty-four cases of EO-previa and 55 cases of LO-previa were analysed. Complete placenta previa at delivery was observed more frequently in the EO-previa group than in the LO-previa group (88.6% vs 47.3%, p<0.001). An emergency caesarean section due to active bleeding was performed more frequently in the EO-previa group (48%) than in the LO-previa group (25%) (p=0.021). The frequency of massive haemorrage (>2500ml) during caesarean section was higher in the EO-previa group than in the LO-previa group (25% vs 9%, p=0.033). Placenta previa was associated with a high risk of bleeding leading to emergency caesarean section during pregnancy, and massive haemorrhage during caesarean section in patients in whom the uterine isthmus opened before 25 weeks of gestation.

The aim of the study was to update the clinical database of chronic wounds in order to derive an evidence based understanding of the condition and hence to guide future clinical management in China. A total of 241 patients from January 1, 2011 to April 30, 2016 with chronic wounds of more than 2 weeks' duration were studied in wound healing department in Shanghai. Results revealed that among all the patients the mean age was 52.5 ± 20.2 years (range 2-92 years). The mean initial area of wounds was 30.3 ± 63.0 cm 2 (range 0.25-468 cm 2 ). The mean duration of wounds was 68.5 ± 175.2 months (range 0.5-840 months). The previously reported causes of chronic wounds were traumatic or surgical wounds (n = 82, 34.0%), followed by pressure ulcers (n = 59, 24.5%). To study the effects of age, patients were divided into 2 groups: less than 60 years (<60), and 60 years or older (≥60). The proportion of wounds etiology between the 2 age groups was analyzed, and there was significant statistical difference ( P < .05, 95% confidence interval [CI] = 0.076-0.987). To study the associations between outcome and clinical characteristics in chronic wounds, chi-square test was used. There were significant differences in the factor of wound infection. ( P = .035, 95% CI = 0.031-0.038) Regarding therapies, 72.6% (n = 175) of the patients were treated with negative pressure wound therapy. Among all the patients, 29.9% (n = 72) of them were completely healed when discharged while 62.7% (n = 150) of them improved. The mean treatment cost was 12055.4 ± 9206.3 Chinese Yuan (range 891-63626 Chinese Yuan). In conclusion, traumatic or surgical wounds have recently become the leading cause of chronic wounds in Shanghai, China. Etiology of the 2 age groups was different. Infection could significantly influence the wound outcome.

Corneal wound healing is an enormously complex process that requires the simultaneous cellular integration of multiple soluble biochemical cues, as well as cellular responses to the intrinsic chemistry and biophysical attributes associated with the matrix of the wound space. Here, we document how the biomechanics of the corneal stroma are altered through the course of wound repair following keratoablative procedures in rabbits. Further we documented the influence that substrate stiffness has on stromal cell mechanics. Following corneal epithelial debridement, New Zealand white rabbits underwent phototherapeutic keratectomy (PTK) on the right eye (OD). Wound healing was monitored using advanced imaging modalities. Rabbits were euthanized and corneas were harvested at various time points following PTK. Tissues were characterized for biomechanics with atomic force microscopy and with histology to assess inflammation and fibrosis. Factor analysis was performed to determine any discernable patterns in wound healing parameters. The matrix associated with the wound space was stiffest at 7days post PTK. The greatest number of inflammatory cells were observed 3days after wounding. The highest number of myofibroblasts and the greatest degree of fibrosis occurred 21days after wounding. While all clinical parameters returned to normal values 400days after wounding, the elastic modulus remained greater than pre-surgical values. Factor analysis demonstrated dynamic remodeling of stroma occurs between days 10 and 42 during corneal stromal wound repair. Elastic modulus of the anterior corneal stroma is dramatically altered following PTK and its changes coincide initially with the development of edema and inflammation, and later with formation of stromal haze and population of the wound space with myofibroblasts. Factor analysis demonstrates strongest correlation between elastic modulus, myofibroblasts, fibrosis and stromal haze thickness, and between edema and central corneal

Multifunctional activities of KSLW synthetic antimicrobial decapeptide: Implications for wound healing

Wound healing is a complex process leading to the maintenance of skin integrity. Stress is known to increase susceptibility to bacterial infection, alter proinflammatory cytokine expression, and delay wound closure. Recently, antimicrobial peptides have generated interest due to their prokaryotic selectivity, decreased microbial resistance and multifunctional roles in wound healing, including fibroblast stimulation, keratinocyte migration and leukocyte migration. The objective of this dissertation project was to evaluate the effect of a synthetic antimicrobial decapeptide (KSLW) on bacterial clearance inflammation, and wound closure during stress-impaired healing. SKH-1 mice were randomly assigned to either control or restraint-stressed (RST) groups. Punch biopsy wounds (3.5 mm in diameter) were created bilaterally on the dorsal skin. Wounds were injected with 50 microL of empty carriers or KSLW prepared in Pluronic-F68, phospholipid micelles, or saline. Bacterial assays of harvested wounds were conducted on BHI agar. Wound closure was determined by photoplanimetry. Cytokine and growth factor mRNA expression was assessed with real-time RT-PCR. Human neutrophil migration assays and checkerboard analyses were performed using Transweli plates, and counting on hemacytometer. Oxidative burst activity was measured by spectrophotometric analysis of 2,7-dichlorofluorescein oxidation. KSLW-treatment resulted in significant reductions in bacterial load among RST mice, with no difference from control after 24h. The effect was sustained 5 days post-wounding, in RST mice treated with KSLW-F68. Temporal analysis of gene induction revealed reversals of stress-induced altered expression of growth factors, proinflammatory cytokines, and chemokines essential for favorable wound healing, at various time points. KSLW-treatment in RST mice demonstrated faster wound closure throughout the stress period. KSLW, at micromolar concentrations, demonstrated a significant effect on neutrophil

Wound healing is a complex process with many potential factors that can delay healing. There is increasing interest in the effects of bacteria on the processes of wound healing. All chronic wounds are colonized by bacteria, with low levels of bacteria being beneficial to the wound healing process. Wound infection is detrimental to wound healing, but the diagnosis and management of wound infection is controversial, and varies between clinicians. There is increasing recognition of the concept of critical colonization or local infection, when wound healing may be delayed in the absence of the typical clinical features of infection. The progression from wound colonization to infection depends not only on the bacterial count or the species present, but also on the host immune response, the number of different species present, the virulence of the organisms and synergistic interactions between the different species. There is increasing evidence that bacteria within chronic wounds live within biofilm communities, in which the bacteria are protected from host defences and develop resistance to antibiotic treatment. An appreciation of the factors affecting the progression from colonization to infection can help clinicians with the interpretation of clinical findings and microbiological investigations in patients with chronic wounds. An understanding of the physiology and interactions within multi-species biofilms may aid the development of more effective methods of treating infected and poorly healing wounds. The emergence of consensus guidelines has helped to optimize clinical management.
