We sought to examine the rate of wound complications in extremely obese women according to postcesarean dressings (NPWT [PICO, Smith & Nephew, St. Peterburg, FL] versus standard dressings).RESULTS: Of 179 extremely obese women, 73 (40.8%) and 106 (59.2%) received NPWT and standard dressings, respectively; 61 women who received NPWT were matched to 61 women who received standard dressings. The rates of the primary outcome in the unmatched cohort were similar between women who received NPWT and those who received standard dressings (20.6 versus 16.0%; p = .44). The rates of primary outcome remained similar between women who received NPWT and those who received standard dressings after matching (18.0 versus 18.0%; p = 1.00).STUDY DESIGN: This was a retrospective cohort study of all extremely obese women (BMI >= 50 kg/m<sup>2</sup>) at 23 weeks' gestation or greater who underwent cesarean delivery at an academic teaching hospital in Washington, DC, between January 2009 and September 2017.

CONCLUSION: In extremely obese women undergoing cesarean delivery, prophylactic PICO NPWT was not associated with a decreased risk of the primary outcome compared with standard dressings. A large prospective randomized controlled trial would be useful to answer if NPWT is beneficial for extremely obese women.
