Abstract
OBJECTIVE To identify procedures to reduce maternal morbidity during cesarean. MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE® method with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane and EMBASE databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Of the 27 questions, there was agreement between the working group and the external reviewers on 26. The level of evidence of the literature was insufficient to provide a recommendation on 15 questions. Preventing hypothermia is recommended to increase maternal satisfaction and comfort (weak recommendation) and to reduce neonatal hypothermia (strong recommendation). The quality of the evidence of the literature did not allow to recommend the skin disinfectant to be used nor the relevance of a preoperative vaginal disinfection nor the choice between the use or nonuse of an indwelling bladder catheterization (if micturition takes place 1 hour before the cesarean section). The Misgav-Ladach technique or its analogues should be considered rather than the Pfannenstiel technique to reduce maternal morbidity (weak recommendation) bladder flap before uterine incision should not be performed routinely (weak recommendation), but a blunt (weak recommendation) and cephalad-caudad extension of uterine incision (weak recommendation) should be considered to reduce maternal morbidity. Antibiotic prophylaxis is recommended to reduce maternal infectious morbidity (strong recommendation) without recommendation on its type or the timing of administration (before incision or after cord clamping). The administration of carbetocin after cord clamping does not significantly decrease the incidence of blood loss>1000 ml, anemia, or blood transfusion compared with the administration of oxytocin. Thus, it is not recommended to use carbetocin rather than oxytocin in cesarean. It is recommended that systematic manual removal of the placenta not to be performed (weak recommendation). An antiemetic should be administered after cord clamping in women having a planned cesarean under locoregional anaesthesia to reduce intraoperative and postoperative nausea and vomiting (strong recommendation) with no recommendation regarding choice of use one or two antiemetics. The level of evidence of the literature was insufficient to provide any recommendation concerning single or double-layer closure of the uterine incision, or the uterine exteriorization. Closing the peritoneum (visceral or parietal) should not be considered (weak recommendation). The quality of the evidence of the literature was not sufficient to provide recommendation on systematic subcutaneous closure, including in obese or overweight patients, or the use of subcuticular suture in obese or overweight patients. The use of subcuticular suture in comparison with skin closure by staples was not considered as a recommendation due to the absence of a consensus in the external review rounds. CONCLUSION In case of cesarean, preventing hypothermia, administering antiemetic and antibiotic prophylaxis after cord clamping are the only strong recommendations. The Misgav-Ladach technique, the way of performing uterine incision (no systematic bladder flap, blunt cephalad-caudad extension), not performing routine manual removal of the placenta nor closure of the peritoneum are weak recommendations and may reduce maternal morbidity.

Abstract
The cesarean section is utilized to deliver babies since the late 19th century. Nowadays, the frequency of cesarean section is increased, mainly because of the low rate of complications and for the increasing demand from future mothers, scared by the idea of painful labor. Although the technique to perform cesarean section has been refined over time, infections, hemorrhage, pain and other consequences still represent matter of debate. To try to reduce the incidence of these complications many trials, randomized or not, have been performed, with the aim to analyze different technical aspects of this surgery. The aim of our review was to resume all the evidence-based instructions on how to best approach to cesarean section practice, in a step-to-step fashion, considering pre-operative actions, opening and closing steps, and postoperative prophylaxis.

Abstract
Cesarean delivery is one of the most frequently performed surgeries in women throughout the world. However, the most optimal technique to minimize maternal and fetal morbidities is still being debated due to various clinical situations and surgeons' preferences. The contentious topics are the use of vacuum devices other than traditional fundal pressure to assist in the delivery of the fetal head and the techniques of uterine repair used during cesarean deliveries. There are two well-described techniques for suturing the uterus: The uterus can be repaired either temporarily exteriorized (out of abdominal cavity) or in situ (within the peritoneal cavity). Numerous studies have attempted to compare these two techniques in different aspects, including operative time, blood loss, and maternal and fetal outcomes. This review provides an overview of the assistive method of vacuum devices compared with fundal pressure, and the two surgical techniques for uterine repair following cesarean delivery. This descriptive literature review was performed to address important issues for clinical practitioners. It aims to compare the advantages and disadvantages of the assistive methods and surgical techniques used in cesarean deliveries. All of the articles were retrieved from the databases Medline and PubMed using the search terms cesarean delivery, vacuum, and exteriorization. The searching results revealed that after exclusion, there were 9 and 13 eligible articles for vacuum assisted cesarean delivery and uterine exteriorization, respectively. Although several studies have concluded vacuum assistance for fetal extraction as a simple, effective, and beneficial method during fetal head delivery during cesarean delivery, further research is still required to clarify the safety of vacuum assistance. In general, compared to the use of in situ uterine repairs during cesarean delivery, uterine exteriorization for repairs may have benefits of less blood loss and shorter operative time. However, it may also carry a higher risk of intraoperative complications such as nausea and vomiting, uterine atony, and a longer time to the return of bowel function. Clinicians should consider these factors during shared decision-making with their pregnant patients to determine the most suitable techniques for cesarean deliveries.

Abstract
O-ring retractors (Alexis/Mobius) have been shown to reduce the risk of Surgical site infection (SSI) following general abdominal surgery. The benefit at caesarean section (CS) remains to be established given the relatively high cost. OBJECTIVES To assess the efficacy of O-ring retractors when used at CS. STUDY DESIGN Systematic review and meta-analysis. Electronic databases were searched from inception of each database until January 2018. No language restrictions were applied. All randomised controlled trials (RCTs) which compared the use of an O-ring retractor to routine care at CS were included. Primary outcome was SSI. Secondary outcomes were operating time, estimated blood loss, need for blood transfusion, need to exteriorise the uterus, requirement for additional postoperative analgesia and adequate operative field visualisation. Analysis was performed using Revman 5.3. RESULTS 6 RCTs were included in the qualitative synthesis and the meta-analysis. This included 1669 women. The use of O-ring retractors did not reduce the risk of SSI when used at CS RR 0.76 (95% CI 0.34-1.70). Nor did the use of O-ring retractors reduce the operating time, estimated blood loss, the need for blood transfusion or the need for additional postoperative analgesia. The use O-ring retractors did reduce the need for exteriorisation of the uterus RR 0.48 (95% CI 0.33-0.69), and did increase the rate of adequate visualisation of the operative field RR 1.05 (95% CI 1.00-1.10). In a planned subgroup analysis there was a reduction in the rate of SSI with the use of O-ring retractors in women with a BMI < 35 RR 0.34(95% CI 0.12-0.98). CONCLUSION This review has shown that O-ring retractors do not reduce the incidence of the common measurable complications of CS; SSI, blood loss, need for blood transfusion and need for additional postoperative analgesia. There may be a subgroup where these retractors are useful, but present evidence does not justify their routine use at CS.

Abstract
Cesarean delivery (CD) is one of the most common procedures performed in the United States, accounting for 32% of all deliveries. Postpartum surgical site infection (SSI), wound infection and endometritis is a major cause of prolonged hospital stay and poses a burden to the health care system. SSIs complicate a significant number of patients who undergo CD - 2-7% will experience sound infections and 2-16% will develop endometritis. Many risk factors for SSI have been described. These include maternal factors (such as tobacco use; limited prenatal care; obesity; corticosteroid use; nulliparity; twin gestations; and previous CD), intrapartum and operative factors (such as chorioamnionitis; premature rupture of membranes; prolonged rupture of membranes; prolonged labor, particularly prolonged second stage; large incision length; subcutaneous tissue thickness > 3 cm; subcutaneous hematoma; lack of antibiotic prophylaxis; emergency delivery; and excessive blood loss), and obstetrical care on the teaching service of an academic institution. Effective interventions to decrease surgical site infection include prophylactic antibiotic use (preoperative first generation cephalosporin and intravenous azithromycin), chlorhexidine skin preparation instead of iodine, hair removal using clippers instead of razors, vaginal cleansing by povidone-iodine, placental removal by traction of the umbilical cord instead of by manual removal, suture closure of subcutaneous tissue if the wound thickness is >2 cm, and skin closure with sutures instead of with staples. Implementation of surgical bundles in non-obstetric patients has been promising., Creating a similar patient care bundle comprised evidence-based elements in patients who undergo CD may decrease the incidence of this major complication. Each hospital has the opportunity to create its own CD surgical bundle to decrease surgical site infection.

Abstract
Surgical site infection (SSI) is one of the most common complications following cesarean section, and has an incidence of 3%-15%. It places physical and emotional burdens on the mother herself and a significant financial burden on the health care system. Moreover, SSI is associated with a maternal mortality rate of up to 3%. With the global increase in cesarean section rate, it is expected that the occurrence of SSI will increase in parallel, hence its clinical significance. Given its substantial implications, recognizing the consequences and developing strategies to diagnose, prevent, and treat SSI are essential for reducing postcesarean morbidity and mortality. Optimization of maternal comorbidities, appropriate antibiotic prophylaxis, and evidence-based surgical techniques are some of the practices proven to be effective in reducing the incidence of SSI. In this review, we describe the biological mechanism of SSI and risk factors for its occurrence and summarize recent key clinical trials investigating preoperative, intraoperative, and postoperative practices to reduce SSI incidence. It is prudent that the surgical team who perform cesarean sections be familiar with these practices and apply them as needed to minimize maternal morbidity and mortality related to SSI.

Abstract
AIM To evaluate intraoperative and early postoperative outcomes of a novel placenta delivery technique; extra-abdominal removal vs. intra-abdominal removal of the placenta during cesarean section (CS). METHODS A total of 210 women delivering by CS at term in a tertiary university hospital between March 2014 and January 2015 were randomized to extra-abdominal removal vs. intra-abdominal removal of the placenta. The women were randomly allocated to the extra- (group 1) or intra-abdominal removal group (group 2) according to random sampling method, where women with even and odd numbers were allocated to intra- and extra-abdominal groups, respectively. The amount of intra-abdominal hemorrhagic fluid accumulation, the duration of operation and estimated blood loss during operation were the primary outcomes. The secondary outcomes included the mean difference between pre- and post-operative hemoglobin and hematocrit levels, the mean postoperative pain score, any additional need of analgesia, postoperative bowel function, postoperative endometritis and wound infections. RESULTS The amount of aspirated hemorrhagic fluid was significantly higher in the intra-abdominal group compared to the extra-abdominal group (34.6±22.2 mL vs. 9.4±4.8 mL, P<0.001). Mean duration of the operation, intraoperative blood loss, postoperative requirement of additional analgesia, postoperative pain scores, postoperative endometritis or wound infection, and length of hospital stay were not significantly different between the intra- and extra-abdominal placental removal groups. CONCLUSION By extra-abdominal removal of the placenta, the accumulation of bloody fluid in the abdominal cavity is significantly less compared to the intra-abdominal removal method, which, in turn, provides avoidance of excessive mounted-gauze use, intra-abdominal manipulations, or iatrogenic trauma.

Abstract
Cesarean delivery (CD) is one of the most common major surgeries performed in the United States and worldwide. Surgical techniques evaluated in well-designed randomized controlled trials (RCTs) that demonstrate maternal benefit should be incorporated into practice. The objective of this review is to provide a summary of surgical techniques of the procedure and review the evidence basis for them for the nonobstetrician. The following techniques with the strongest evidence should be commonly performed, when feasible: (1) prophylactic antibiotics with a single dose of ampicillin or first-generation cephalosporin prior to skin incision; (2) postpartum hemorrhage prevention with oxytocin infusion of 10 to 40 IU in 1 L crystalloid over 4 to 8 hours; (3) low transverse skin incision; (4) blunt or sharp subcutaneous and fascial expansion; (5) blunt, cephalad-caudad uterine incision expansion; (6) spontaneous placental removal; (7) blunt-tip needle usage during closure; (8) subcutaneous suture closure (running or interrupted) if thickness is ≥2 cm; and (9) skin closure with suture. Although the number of RCTs designed to optimize maternal and neonatal outcomes of this common procedure is encouraging, further work is needed to minimize surgical morbidity. Optimal methods for postpartum hemorrhage prevention, adhesion prevention, and venous thromboembolism prophylaxis remain ongoing areas of active research, with outcomes that could markedly improve maternal morbidity and mortality. If evidence of a surgical technique appears preferred over another, clinicians should be comfortable adopting the evidence-based technique when performing and teaching CD.

Abstract
BACKGROUND Surgical site infections (SSIs) are an important cause of morbidity following cesarean delivery, particularly in obese patients. Methods to reduce SSIs after cesarean delivery would have an important impact in obese obstetric patients. OBJECTIVE The purpose of this study was to determine whether the Alexis O cesarean delivery retractor, a barrier self-retaining retractor, reduces SSIs and wound disruptions in obese patients undergoing cesarean delivery. STUDY DESIGN This was a randomized controlled trial of obese women (body mass index ≥ 30 kg/m(2)) undergoing nonemergent cesarean delivery. Patients were randomized to the treatment group (using the Alexis O cesarean delivery retractor) or to the control group (using conventional handheld retractors). The primary outcome was SSI or wound disruption during the 30 day postoperative period. Secondary outcomes included operative time, estimated blood loss, change in hemoglobin, antiemetic use, length of postoperative hospital stay, hospital readmission, and other postoperative complications. RESULTS A total of 301 patients were enrolled in the study. One hundred forty-four patients were randomized to the treatment group and 157 to the control group. Baseline characteristics and indications for cesarean delivery were similar between the 2 groups. Median body mass index was 40.1 kg/m(2). There were no significant differences between the treatment and the control group in the primary outcome of SSI or wound disruption rates at the 30 day assessment (20.6% vs 17.6%, P = .62), during the postoperative inpatient hospitalization or at the 1-2 week postoperative visit. There were also no differences in the primary outcome when adjusting for obesity class or thickness of the subcuticular layer. Patients in the treatment group had lower rates of uterine exteriorization (54.3% vs 87.3%, P < .001), but there were no differences in all other outcomes. CONCLUSION Use of the Alexis retractor in cesarean delivery deliveries did not decrease SSI or wound disruption rates in an obese population. Its use as a retractor should be left to the discretion of the surgeon and clinical circumstances.

Abstract
The aim of this study was to evaluate the reported techniques used in caesarean sections in order to form a general perspective of the procedural options for this frequently performed operation. The PubMed database and Cochrane Reviews were searched separately with the key words 'caesarean', 'abdominal entry', 'abdominal incision', 'uterine repair', 'peritoneal repair', 'closure of abdominal incision', 'suture materials', 'extraction of the placenta' and 'review'. Reviews, meta-analyses and prospective randomised trials were included in this review. In conclusion, although caesarean delivery is a very common operation, standardised and globally accepted techniques for caesarean section have not been described. The best surgical techniques for this operation are still unknown. Although the long-term follow-up results from two large, prospective, randomised studies are pending, further research is needed to establish an evidence-based, standardised approach for caesarean sections.

Abstract
BACKGROUND The goal of the present study was to investigate the wound-healing potential of marine collagen peptides (MCPs) from chum salmon skin administered to rats following cesarean section (CS). METHODS Ninety-six pregnant Sprague-Dawley rats were randomly divided into four groups: a vehicle group and three MCP groups. After CS, rats were intragastrically given MCPs at doses of 0, 0.13, 0.38, 1.15 g/kg*bw, respectively. On postoperative days 7, 14, and 21, the uterine bursting pressure, skin tensile strength, hydroxyproline (Hyp) concentrations, and histological and immunohistochemical characteristics of the scar tissue were examined. RESULTS In the MCP groups, the skin tensile strength, uterine bursting pressure, and Hyp were significantly higher than those in the vehicle group at all three time points (p<0.05). The formation of capillary, fibroblast, and collagen fiber, the expression of platelet-endothelial cell adhesion molecule-1, basic fibroblast growth factor, and transforming growth factor beta-1 were increased in the MCP groups (p<0.05). CONCLUSION MCPs could accelerate the process of wounding healing in rats after CS.

Abstract
The objective of our systematic review was to provide updated evidence-based guidance for surgical decisions during cesarean delivery (CD). We performed an English-language MEDLINE, PubMed, and COCHRANE search with the terms, cesarean section, cesarean delivery, cesarean, pregnancy, and randomized trials, plus each technical aspect of CD. Randomized control trials (RCTs) involving any aspect of CD technique from Jan. 1, 2005, to Sept. 1, 2012, were evaluated to update a previous systematic review. We also summarized Cochrane reviews, systematic reviews, and metaanalyses if they included additional RCTs since this review. We identified 73 RCTs, 10 metaanalyses and/or systematic reviews, and 12 Cochrane reviews during this time frame. Recommendations with high levels of certainty as defined by the US Preventive Services Task Force favor pre-skin incision prophylactic antibiotics, cephalad-caudad blunt uterine extension, spontaneous placental removal, surgeon preference on uterine exteriorization, single-layer uterine closure when future fertility is undesired, and suture closure of the subcutaneous tissue when thickness is 2 cm or greater and do not favor manual cervical dilation, subcutaneous drains, or supplemental oxygen for the reduction of morbidity from infection. The technical aspect of CD with high-quality, evidence-based recommendations should be adopted. Although 73 RCTs over the past 8 years is encouraging, additional well-designed, adequately powered trials on the specific technical aspects of CD are warranted.

Abstract
BACKGROUND 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. METHODS 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. FINDINGS 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-closure 1·06 (0·94-1·20), and chromic catgut versus polyglactin-910 0·90 (0·78-1·04). 144 serious adverse events were reported, of which 26 were possibly related to the intervention. Most of the reported serious adverse events were known complications of surgery or complications of the reasons for the caesarean section. INTERPRETATION These findings suggest that any of these surgical techniques is acceptable. However, longer-term follow-up is needed to assess whether the absence of evidence of short-term effects will translate into an absence of long-term effects.

Abstract
Cesarean section is the most common surgery performed in the United States with over 30% of deliveries occurring via this route. This number is likely to increase given decreasing rates of vaginal birth after cesarean section (VBAC) and primary cesarean delivery on maternal request, which carries the inherent risk for intraoperative complications. Urologic injury is the most common injury at the time of either obstetric or gynecologic surgery, with the bladder being the most frequent organ damaged. Risk factors for bladder injury during cesarean section include previous cesarean delivery, adhesions, emergent cesarean delivery, and cesarean section performed at the time of the second stage of labor. Fortunately, most bladder injuries are recognized at the time of surgery, which is important, as quick recognition and repair are associated with a significant reduction in patient mortality. Although cesarean delivery is a cornerstone of obstetrics, there is a paucity of data in the literature either supporting or refuting specific techniques that are performed today. There is evidence to support double-layer closure of the hysterotomy, the routine use of adhesive barriers, and performing a Pfannenstiel skin incision versus a vertical midline subumbilical incision to decrease the risk for bladder injury during cesarean section. There is also no evidence that supports the creation of a bladder flap, although routinely performed during cesarean section, as a method to reduce the risk of bladder injury. Finally, more research is needed to determine if indwelling catheterization, exteriorization of the uterus, and methods to extend hysterotomy incision lead to bladder injury.

Abstract
PURPOSE OF REVIEW Cesarean section is the most common surgical procedure performed on US women, and rates of cesarean delivery continue to increase. RECENT FINDINGS Recent studies on operative technique in cesarean section have contributed significantly to our knowledge of antibiotic prophylaxis, bladder flap formation, management of the uterine repair and closure of the peritoneum and skin. There is compelling evidence that antibiotics should be given prior to skin incision rather than the traditional administration after cord clamping. Additionally, evidence suggesting benefit to multiagent, extended-coverage regimens is mounting. Recent studies challenge the accepted practice of creating a bladder flap in cesarean section. Uterine repair can be safely accomplished either intra or extraabdominally but the debate over single versus double-layer closure continues. Nonclosure of the visceral peritoneum confers significant benefit, but recent evidence suggests that closure of the parietal layer may be advantageous with respect to future adhesions. SUMMARY It is imperative that all technical aspects in cesarean section continue to be challenged. Widely accepted aspects, including antibiotics administration at cord clamping and creation of a bladder flap, may not be best practice.
