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.

Further study details as provided by Mark Chames, MD, University of Michigan:

Primary Outcome Measures:
  • Number of Patients Who Experience One or More Wound Complications [ Time Frame: 6 weeks ]
    A composite of cellulitis, wound dehiscence, seroma, hematoma, abscess, and fascial dehiscence from wound evaluation at any point within six weeks, as pulled from the medical record or based on patient report.

Secondary Outcome Measures:
  • Febrile Morbidity [ Time Frame: 2 days, 6 weeks ]
    Febrile morbidity would be measured by number of participants who experienced fever as a sign of infection at 2 days, and overall within 6 weeks of delivery.

  • Patient Report of Pain Severity and Control [ Time Frame: 6 weeks ]
    Self Reported pain, on a scale from 1 to 10, where 1 is little pain and 10 is extreme pain

Enrollment: 37

Arms Assigned Interventions
Placebo Comparator: Standard Dressing
Obese patients undergoing cesarean section in this arm will receive a standard island-type dressing
Device: Standard Dressing
Standard island dressing. Patients who receive a standard dressing will have that dressing removed on postoperative day 2. This will be left in place until the patient is seen for follow up by the visiting nurse.
Experimental: Silverlon
Obese patients undergoing cesarean section in this arm will receive Silverlon, a silver impregnated dressing
Device: Silverlon

Patients will be randomized to either receive a silver dressing. 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.

Detailed Description:
This study's purpose was to evaluate the effect of a FDA approved silver-impregnated dressing on cesarean wound complications in obese women. It was initiated and 37 women were randomized, but because of logistical barriers, we were unable to gather outcome data either by the intended survey or by chart review. When it became clear that we would be unable to complete the study, recruitment was terminated and further attempts at data gathering were stopped. While a small number of photographs were taken as intended, they were lost due to a technological failure prior to any analysis. Therefore no outcome data could be analyzed. Nonetheless, as patients of the University of Michigan Health System, all research subjects received health care treatment appropriate to their medical condition and circumstances.
