A Systematic Review and Meta-Analysis of Wound Complications after a Caesarean Section in Obese Women.

ABSTRACT: (1) Background: Caesarean sections in obese patients are associated with an increased risk of surgical wound complications, including hematomas, seromas, abscesses, dehiscence, and surgical site infections. The aim of the present study is to perform a meta-analysis and systematic review of the current literature focusing on the strategies available to decrease wound complications in this population. (2) Methods: We reviewed the data available from the PubMed and the Science Direct databases concerning wound complications after caesarean sections in obese women. The following key words were used: "caesarean section", "cesarean section", "wound complication", "wound morbidity", and "wound infection". A total of 540 papers were retrieved, 40 of which were selected for the final systematic review and whereas 21 articles provided data for meta-analysis. (3) Results: The conducted meta-analyses revealed that the use of prophylactic drainage does not increase the risk of wound complications in obese women after a caesarean sections (pooled OR = 1.32; 95% CI 0.64-2.70, p = 0.45) and that vertical skin incisions increase wound complications (pooled OR = 2.48; 95% CI 1.85-3.32, p < 0.01) in obese women, including extremely obese women. (4) Conclusions: Subcutaneous drainage does not reduce the risk of a wound complications, wound infections, and fever in obese women after caesarean sections. Negative prophylactic pressure wound therapy (NPWT) may reduce the risk of surgical site infections. The evidence of using a prophylactic dose of an antibiotic before the caesarean section is still lacking.

Project description:ObjectiveTo assess the effects on maternal infectious morbidity and neonatal outcomes of the timing of antibiotic prophylaxis in women undergoing caesarean section. A recent National Institute for Health and Clinical Excellence (NICE) guideline reported that antibiotic administration before skin incision reduces the risk of maternal infection; this recommendation was based on a meta-analysis, however one including trials that were not double blind and not including a trial published recently.DesignSystematic review and meta-analysis.Data sourcesSearches of PubMed and EMBASE and reference lists of the retrieved articles.Inclusion criteriaRandomised double-blind controlled trials comparing the administration of antibiotics before skin incision with administration after cord clamping.Data extraction and analysisData on maternal total infectious morbidity, endometritis and wound infection, as well as neonatal intensive care unit admission, neonatal infection and neonatal sepsis were extracted and combined using random effects meta-analysis.ResultsFive studies reporting on 1777 parturients were included in our systematic review. The relative risk (RR) for maternal total infectious morbidity for antibiotic administration before incision compared with antibiotic administration after cord clamping was 0.64 (95% CI 0.36 to 1.15). Likewise, there was no difference in the risk of wound infection (RR 0.72, 95% CI 0.41 to 1.27). Parturients receiving the antibiotic preoperatively had a significantly reduced risk of endometritis (RR 0.48, 95% CI 0.27 to 0.87; number needed to treat 41, 95% CI 23 to 165). Analyses of the neonatal outcome parameters revealed no differences between the regimens of antibiotic administration, but were based on few studies.ConclusionsIn contrast to a recent NICE guideline, we did not find a reduction in total infectious morbidity with antibiotic administration before skin incision; we confirmed a reduction in the risk of endometritis and a lack of effect on the risk for wound infection.

Project description:BackgroundProphylactic antibiotics reduce infectious morbidity from caesarean section. The timing of their administration, however, is a matter of controversy.ObjectivesTo examine maternal and neonatal infectious morbidity in women receiving preoperative prophylaxis compared with those receiving intraoperative administration.Search strategyMedline, Embase, Current Controlled Trials and Cochrane Central were searched from their inception dates to December 2011.Selection criteriaRandomised controlled trials of a single dose of any antibiotic comparing preoperative with intraoperative administration were selected.Data collection and analysisTrial characteristics, outcomes and quality measures, based on the Cochrane tool for risk of bias, were independently extracted. The random effect model of DerSimonian and Laird to estimate relative risks (RRs) for maternal and neonatal outcomes was used.Main resultsSix trials met the inclusion criteria, reporting on 2313 women and 2345 newborns. Preoperative administration was associated with a significant 41% reduction in the rate of endometritis compared with intraoperative administration (RR 0.59; 95% confidence interval [95% CI] 0.37-0.94; I2 0%). In the preoperative group, there were nonsignificant reductions in the rates of wound infection (RR 0.71; 95% CI 0.44-1.14; I2 0%), maternal febrile morbidity (RR 0.94; 95% CI 0.46-1.95; I2 0%), neonatal sepsis (RR 0.81; 95% CI 0.47-1.41; I2 0%), neonatal septic work-up (RR 0.93; 95% CI 0.71-1.21; I2 0%) and neonatal intensive-care unit admission (RR 0.92; 95% CI 0.65-1.28; I2 0%). There were nonsignificant increases in the rates of maternal pyelonephritis (RR 1.09; 95% CI 0.49-2.43; I2 0%) and neonatal pneumonia (RR 3.36; 95% CI 0.55-20.47; I2 0%).ConclusionsCompared with intraoperative administration, preoperative antibiotics significantly reduce the rate of endometritis. The lack of neonatal adverse effects should be cautiously interpreted given the limited power of the trials to detect such effects.

Project description:Background:Caesarean section rates have increased worldwide in recent decades. Caesarean section is an essential maternal healthcare service. However, it has both maternal and neonatal adverse outcomes. Therefore this systematic review and meta-analysis aimed to estimate the prevalence, indication, and outcomes of caesarean section in Ethiopia. Methods:Twenty three cross-sectional studies with a total population of 36,705 were included. Online databases (PubMed/Medline, Hinari, Web of Science, and Google Scholar) and online university repository was used. All the included papers were extracted and appraised using the standard extraction sheet format and Joanna Briggs Institute respectively. The pooled prevalence of the caesarean section, indications, and outcomes was calculated using the random-effect model. Result:The overall pooled prevalence of Caesarean section was 29.55% (95% CI: 25.46-33.65). Caesarean section is associated with both maternal and neonatal complications. Cephalopelvic disproportion [18.13%(95%CI: 12.72-23.53] was the most common indication of Caesarean section followed by non-reassuring fetal heart rate pattern [19.57% (95%CI: 16.06-23.08]. The common neonatal complications following Caesarean section included low APGAR score, perinatal asphyxia, neonatal sepsis, meconium aspiration syndrome, early neonatal death, stillbirth, and prematurity whereas febrile morbidity, surgical site infection, maternal mortality, severe anemia, and postpartum hemorrhage were the most common maternal complications following Caesarean section. Conclusion:In this systematic review and meta-analysis, the rate of Cesarean section was high. Cephalopelvic disproportion, low Apgar score, and febrile morbidity were the most common indication of Caesarean section, neonatal outcome and maternal morbidity following Caesarean section respectively. Increasing unjustified Caesarean section deliveries as a way to increase different neonatal and maternal complications, then several interventions needed to target both the education of professionals and the public.

Project description:ObjectivesAssess the effects of different routes of prophylactic oxytocin administration for preventing blood loss at caesarean section (CS).DesignSystematic review and meta-analysis.MethodsMedline, EMBASE, CINAHL, Cochrane Library, BVS, SciELO and Global Index Medicus were searched through 24 May 2020 for randomised controlled trials (RCTs) comparing different routes of prophylactic oxytocin administration during CS. Study selection, data extraction and quality assessment were conducted by two investigators independently. We pooled results in fixed effects meta-analyses and calculated average risk ratio (RR), mean difference (MD) and 95% CI. We used GRADE to assess the overall quality of evidence for each outcome.ResultsThree trials (180 women) were included in the review. All studies compared intramyometrial (IMY) versus intravenous oxytocin in women having prelabour CS. IMY compared with intravenous oxytocin administration may result in little or no difference in the incidence of postpartum haemorrhage (RR 0.14, 95% CI 0.01 to 2.70; N=100 participants; 1 RCT), hypotension (RR 1.00, 95% CI 0.29 to 3.45; N=40; 1 RCT), headache (RR 3.00, 95% CI 0.13 to 69.52; N=40; 1 RCT) or facial flushing (RR 0.50, 95% CI 0.05 to 5.08; N=40; 1 RCT); IMY oxytocin may reduce nausea/vomiting (RR 0.13, 95% CI 0.02 to 0.69; N=140; 2 RCTs). We are very uncertain about the effect IMY versus intravenous oxytocin on the need for additional uterotonics (RR 0.82; 95% CI 0.25 to 2.69; N=140; 2 RCTs). IMY oxytocin may reduce blood loss slightly (MD -57.40 mL, 95% CI -101.71 to -13.09; N=40; 1 RCT).ConclusionsThere is limited, low to very low certainty evidence on the effects of IMY versus intravenous oxytocin at CS for preventing blood loss. The evidence is insufficient to support choosing one route over another. More trials, including studies that assess intramuscular oxytocin administration, are needed on this relevant question.Prospero registration numberCRD42020186797.

Project description:ObjectiveTo determine the effectiveness of closed incision negative pressure wound therapy (NPWT) compared with standard dressings in preventing surgical site infection (SSI) in obese women undergoing caesarean section.DesignMulticentre, pragmatic, randomised, controlled, parallel group, superiority trial.SettingFour Australian tertiary hospitals between October 2015 and November 2019.ParticipantsEligible women had a pre-pregnancy body mass index of 30 or greater and gave birth by elective or semi-urgent caesarean section.Intervention2035 consenting women were randomised before the caesarean procedure to closed incision NPWT (n=1017) or standard dressing (n=1018). Allocation was concealed until skin closure.Main outcome measuresThe primary outcome was cumulative incidence of SSI. Secondary outcomes included depth of SSI (superficial, deep, or organ/body space), rates of wound complications (dehiscence, haematoma, seroma, bleeding, bruising), length of stay in hospital, and rates of dressing related adverse events. Women and clinicians were not masked, but the outcome assessors and statistician were blinded to treatment allocation. The pre-specified primary intention to treat analysis was based on a conservative assumption of no SSI for a minority of women (n=28) with missing outcome data. Post hoc sensitivity analyses included best case analysis and complete case analysis.ResultsIn the primary intention to treat analysis, SSI occurred in 75 (7.4%) women treated with closed incision NPWT and in 99 (9.7%) women with a standard dressing (risk ratio 0.76, 95% confidence interval 0.57 to 1.01; P=0.06). Post hoc sensitivity analyses to explore the effect of missing data found the same direction of effect (closed incision NPWT reducing SSI), with statistical significance. Blistering occurred in 40/996 (4.0%) women who received closed incision NPWT and in 23/983 (2.3%) who received the standard dressing (risk ratio 1.72, 1.04 to 2.85; P=0.03).ConclusionProphylactic closed incision NPWT for obese women after caesarean section resulted in a 24% reduction in the risk of SSI (3% reduction in absolute risk) compared with standard dressings. This difference was close to statistical significance, but it likely underestimates the effectiveness of closed incision NPWT in this population. The results of the conservative primary analysis, multivariable adjusted model, and post hoc sensitivity analysis need to be considered alongside the growing body of evidence of the benefit of closed incision NPWT and given the number of obese women undergoing caesarean section globally. The decision to use closed incision NPWT must also be weighed against the increases in skin blistering and economic considerations and should be based on shared decision making with patients.Trial registrationANZCTR identifier 12615000286549.

Project description:BackgroundThe trend of increasing caesarean deliveries in developed countries over the past three decades is now being observed in sub-Saharan African. This rise might be associated with an increase in the complications that could arise from this surgical intervention. We therefore sought to assess the prevalence, indications and complications of caesarean deliveries in Cameroon.MethodsWe systematically searched online databases: Medline; Global Health and the CINAHL from 01st January 1966 to 25th July 2019. We reviewed published cohort studies, retrospective register analysis and cross-sectional studies that described cohorts of pregnant women presenting at delivery facilities in Cameroon; and included those that had an estimate of the proportion of women who delivered by caesarean sections.ResultsThere were 126 articles initially identified by the search and 88 articles were retained after removal of duplicates. After screening of the titles and abstracts, and full text review, we identified 16 articles describing 22 cohorts of women presenting for delivery in health facilities in Cameroon. The overall estimate for the prevalence of caesarean deliveries was 9.9% (95% CI: 7.4, 12.8%, I2?=?99.68%, ?2?=?315.9, p?<?0.001). The prevalence of caesarean deliveries increased progressively from 3.4% (95% CI: 2.2, 4.8%) before the year 2000, to 9.8% (95% CI: 7.4, 12.8%) between 2000 and 2009 and 14.7% (95% CI: 8.8, 21.7%) from 2010 to 2019. The three commonest indications for caesarean deliveries were: cephalopelvic disproportion (27.5%; 95% CI: 17.5, 38.7%); previous caesarean deliveries (13.2%; 95% CI: 7.4, 20.3%) and foetal distress (11.2%; 95% CI: 4.8, 19.5%). Neonates who were born by caesarean delivery were more likely to have neonatal asphyxia when compared with neonates born from vaginal deliveries (OR: 6.5; 95% CI: 2.5, 16.5).ConclusionThe rates of caesarean deliveries in Cameroon falls just within the recommended 10-15% range proposed by the World Health Organisation but have however been increasing progressively in the past decades. There is a strong need to assess the various indications of caesarean deliveries in Cameroon in order to curb its associated complications.
