Abstract

OBJECTIVE: This study aimed to identify evidence-based peripartum interventions for people with a body mass index ≥40 kg/m2. DATA SOURCES: PubMed, MEDLINE, EMBASE, Cochrane, CINAHL, and ClinicalTrials.gov were searched from inception to 2022 without date, publication type, or language restrictions. STUDY ELIGIBILITY CRITERIA: Cohort and randomized controlled trials that implemented an intervention and evaluated peripartum outcomes of people with a body mass index ≥40 kg/m2 were included. The primary outcome depended on the intervention but was commonly related to wound morbidity after cesarean delivery (ie, infection, separation, hematoma). METHODS: Meta-analysis was completed for interventions with at least 2 studies. Pooled risk ratios with 95% confidence intervals and heterogeneity (I2 statistics) were reported. RESULTS: Of 20,301 studies screened, 30 studies (17 cohort and 13 randomized controlled trials) encompassing 10 types of interventions were included. The interventions included delivery planning (induction of labor, planned cesarean delivery), antibiotics during labor induction or for surgical prophylaxis, 6 types of cesarean delivery techniques, and anticoagulation dosing after a cesarean delivery. Planned cesarean delivery compared with planned vaginal delivery did not improve outcomes according to 3 cohort studies. One cohort study compared 3 g with 2 g of cephazolin prophylaxis for cesarean delivery and found no differences in surgical site infections. According to 3 cohort studies and 2 randomized controlled trials, there was no improvement in outcomes with a non–low transverse skin incision. Ten studies (4 cohort and 6 randomized controlled trials) met the inclusion criteria for the meta-analysis. Two randomized controlled trials compared subcuticular closure with suture vs staples after cesarean delivery and found no differences in wound morbidity within 6 weeks of cesarean delivery (n=422; risk ratio, 1.09; 95% confidence interval, 0.75–1.59; I2=9%). Prophylactic negative-pressure wound therapy was compared with standard dressing in 4 cohort and 4 randomized controlled trials, which found no differences in wound morbidity (cohort n=2200; risk ratio, 1.19; 95% confidence interval, 0.88–1.63; I2=66.1%) or surgical site infections (randomized controlled trial n=1262; risk ratio, 0.90; 95% confidence interval, 0.63–1.29; I2=0). CONCLUSION: Few studies address interventions in people with a body mass index ≥40 kg/m2, and most studies did not demonstrate a benefit. Either staples or suture are recommended for subcuticular closure, but available data do not support prophylactic negative-pressure wound therapy after cesarean delivery for people with a body mass index ≥40 kg/m2.
