Brief summary

This proposed prospective, randomized, single-blinded controlled trial will directly compare Stratafix anti-microbial barbed sutures and standard PDS sutures for fascial closure at the time of Cesarean delivery. Primary outcomes will include postoperative pain scores at 24 hours, 48 hours, and two weeks postpartum (both total pain and right-sided abdominal pain commonly associated with the knot from traditional fascial closure), as well as total opioid consumption (morphine milligram equivalents) for the first 48 hours. Secondary outcomes will include length of hospital stay, wound complications (e.g., infection, dehiscence), patient satisfaction measured per the standardized surgical satisfaction questionnaire (SSQ-8), time required for fascial closure (minutes from start to end of fascial closure), and surgical site infections. The hypothesis is that among women undergoing primary Cesarean delivery, fascial closure with barbed suture (Stratafix) will result in lower postoperative pain scores and reduced opioid (narcotic) consumption within the first 48 hours after surgery compared to closure with traditional monofilament suture (PDS).

Detailed description

This prospective, randomized, single-blinded controlled trial will compare Stratafix™ antimicrobial barbed sutures with standard PDS monofilament sutures for fascial closure at Cesarean delivery, evaluating whether barbed sutures improve postoperative recovery. Primary outcomes include postoperative pain scores at 24 hours, 48 hours, and two weeks-capturing both overall pain and the right-sided discomfort often associated with fascial knot placement-as well as total opioid use in the first 48 hours (measured in MMEs). Secondary outcomes include length of hospital stay, wound complications, surgical site infections, fascial closure time, and patient-reported satisfaction using the SSQ-8. The study hypothesizes that barbed suture closure will result in lower pain and reduced opioid consumption compared with traditional PDS closure among women undergoing primary Cesarean delivery.

Interventions

DEVICEPolydioxanone Plus

Polydioxanone Plus (PDS) is a standard monofilament, absorbable suture used for fascial closure at the time of Cesarean delivery. In this study, PDS will be used to approximate the rectus fascia in a continuous running fashion with a traditional terminal knot. This intervention represents the conventional method of fascial closure and serves as the control arm for comparison against Stratafix barbed suture
