Comparing Outcomes Between Standard Mepilex and Mepilex Silver for Tracheotomy Dressings

Objective The purpose of the study is to compare the incidence of early postoperative tracheotomy stoma wound complications in pediatric patients using a silver‐impregnated barrier dressing (Mepilex Ag) versus a standard absorbent foam dressing (standard Mepilex). Methods This is a prospective, non‐blinded, randomized trial of pediatric patients undergoing tracheotomy at a tertiary care children's hospital. Patients were randomized to receive Mepilex Ag versus standard Mepilex tracheostoma dressings following tracheotomy. All patients received standard postoperative wound care and daily stomal examination. Wound related complications, breakdown, granulation, and infection were recorded for the first 7 days after surgery. A non‐inferiority study design was used to test the hypothesis that the Mepilex group had a non‐inferior wound complication rate (within 10% margin) compared to the Mepilex Ag group. Results Eighty‐two patients were enrolled; 52 received Mepilex Ag, and 30 received standard Mepilex. There was no difference between the groups with respect to age, sex, race, surgical indication, or postoperative length of stay. Non‐inferiority testing demonstrated that the Mepilex standard cohort had no more than 10% greater stomal wound complication rate than that of Mepilex Ag dressing group (p = 0.0108). Conclusion Standard Mepilex was found to be non‐inferior to Mepilex Ag in the prevention of tracheotomy stomal wound complications. Standard Mepilex may be used effectively in the postoperative period, potentially reducing costs to caregivers and the institution. Further work is needed to analyze additional factors that could contribute to poor postoperative stoma healing such as bacterial colonization.
