Negative Pressure Wound Therapy-PICO: Cosmesis in Repeat C-Sections

Single, randomized controlled trial in women undergoing a repeat cesarean delivery. Women will be randomized to placement of a PICO 7 dressing or a standard abdominal dressing at the time of cesarean. The standard abdominal dressing will be removed approximately on postoperative day (POD) 1-2 and the PICO 7 dressing will be removed approximately on POD 3-4 (prior to discharge). If the patient with a PICO dressing remains inpatient for longer than 7 postoperative days, the PICO dressing will be removed prior to POD 7, in accordance with device instructions. Participants in both groups will be sent POSAS surveys at the two, four and six week visit window with primary outcome being aesthetic appearance (cosmesis) at six weeks. Observers (healthcare providers) will complete a POSAS survey at the postpartum visit (~4-6 weeks postoperative) to rate scar quality.
