Background: Surgical site infections (SSIs) can occur after colorectal surgery. Ionic silver has been used to prevent the development of SSIs. New-generation dressings, defined as total occlusive ionic silver-containing dressings, have been shown to reduce bacterial colonization in SSIs.
Purpose: To evalute the effect of a silver hydrofiber dressing on the development of SSIs at the abdominal incision after ostomy closure.
Methods: There was a total of 37 eligible patients who underwent temporary ostomy closure. Five patients required an associated intervention during ostomy closure and were excluded. One patient was lost to follow-up. Hence, 32 patients were included in the study. Silver-containing occlusive dressings and conventional dressings were used in patients who underwent ostomy closure. In the control group (n = 16), the wound area was covered with a standard sterile gauze dressing for 24 to 48 hours, and then wound cleansing was performed with 10% povidone iodine, followed by daily dressing replacement with sterile gauze for 5 days. The patients in the study group (n = 16) were treated with a silver-containing hydrofiber dressing, which was not changed for 5 days following application in the operating room.
Results: At the end of the 30-day follow-up period, no SSIs were observed in the study group. When the dressing methods applied to the patient groups with and without SSIs were compared, SSIs developed at a higher rate in the control group (n = 4; 26.7%) compared with the study group (n = 0); this result was statistically significant (P = .043).
Conclusions: In this study, the use of a wound care product containing ionic silver reduced the rate of SSIs related to ostomy closure. Multicenter, randomized, clinical studies involving a larger number of patients are needed. In addition, occlusive wound dressings with and without silver should be investigated in further studies.
