Obese patients undergoing cesarean section are at high risk for wound complications, which occur in approximately 20% of patients. This is a randomized controlled trial designed to determine whether the risk for wound-related complications can be reduced by covering the incision with a silver-impregnated dressing in the postoperative period.

Primary Outcome Measures:
  • Wound complications [ Time Frame: 6 weeks ]
    A composite of cellulitis, wound dehiscence, seroma, hematoma, abscess, and fascial dehiscence

Secondary Outcome Measures:
  • Febrile morbidity [ Time Frame: 2 days, 5 days ]
  • Pain [ Time Frame: 2 days, 6 weeks ]

Estimated Enrollment: 100
Study Start Date: February 2012
Estimated Study Completion Date: February 2013
Estimated Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Dressing Type ( Silverlon)

    Patients will be randomized to either receive a standard dressing or a silver dressings. Patients who receive a standard dressing will have that dressing removed on postoperative day 2. Patients who receive a silver dressing will have that dressing replaced on postoperative day number 2. This will be left in place until the patient is seen for follow up by the visiting nurse.

    All patient will be evaluated by the visiting nurse on postoperative day 4 or 5 and have their wounds photographed. All patients will be contacted for a brief survey 6 weeks postpartum.
