Letter to the Editor

Background: The worst fear of a joint replacement surgeon is infection. Many factors are known to contribute to the development of infection in a surgical set up. Post-operative wound soakage is one of them. Wet wounds lead to repeated dressings, exposing the wound for contamination, risk of infection and increased length of hospital stay. Therefore, any measure to avoid postoperative wound problems is desirable. We wish to report our experience of the use of occlusive, sterile sanitary napkin dressings in routine total hip and knee replacement wounds. Method: In a prospective randomized study, we compared the use of occlusive, sterile sanitary napkin dressings with standard ward gauze dressings in routine hip and knee replacement wounds. We studied 27 patients in two groups (standard dressings and sanitary napkin dressings) for the number of dressing changes required due to wound soakage. Our results showed that use of sanitary napkin dressings reduced the number of dressings, significantly, before staples removal (p= 0.0001). Discussion: Using hydrofibre dressings have been reported to be effective in reducing the number of dressings in patients with lower limb arthroplasty. However, these dressings are expensive and require special manufacturing techniques. The use of sterile, occlusive sanitary napkin dressing in our set up has facilitated us to manage the joint replacement wounds very effectively. This method is simple, inexpensive and reduces the number of man hours and, we believe, reduces the overall cost of the treatment. Conclusion: Convinced by the impressive performance of this dressing in joint replacement wounds, the authors recommend this method, highly, for routine primary and revision joint replacements.
