Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Prophylactic NPWT | Women assigned to prophylactic NPWT will have the Prevena device applied and secured with fixation adhesion strips. The device will be monitored while the patient is in the hospital to confirm that it is functioning well. The device will be removed prior to discharge, typically on postoperative day 4, but longer for up to 7 days for patients who remain hospitalized.~Prophylactic NPWT: The Prevena NPWT system is a small, lightweight, portable suction device consisting of an electric motor-driven vacuum pump connected to a proprietary foam and adhesive dressing. It is supplied as a pump with a sterile dressing kit and two batteries. Different dressing sizes are available for transverse and vertical incisions ranging from 13 to 20 cm and more. The pump maintains negative pressure of -125 mmHg to the wound surface. The device is placed after skin closure. | 29 | 806 | OG000 |
| Group 2 | Standard Dressing | Women assigned to standard care will receive routine postoperative wound dressing consisting of layers of gauze and adhesive tap. The dressing will be removed after 24 - 48 hours.~Standard Dressing: Standard wound dressing is routine postoperative wound dressing consisting of layers of gauze and adhesive tape. | 27 | 802 | OG001 |
