Application of wound dressing Molndal technique in clean and potentially contamined postoperative wounds--initial comparative study.

Because of a possible delayed wound healing, critical colonization and infection of wounds present a problem for surgeons, particularly in patients with compromised immune system or in case where the wound is heavy contaminated or poorly perfused. Molndal technique of wound dressing has proven to be effective in prevention of infection. In our study we wanted to describe the benefits of the application of Molndal technique wound dressing compared to traditional wound dressing technique at potentially contaminated and clean postoperative wounds. We examined postoperative wound after radical excision of pilonidal sinus and after implantation of partial endoprosthesis in hip fracture. Molndal technique consisted of wound dressing with Aquacel Ag - Hydrofiber. Traditional technique was performed using gauze compresses and hypoallergic adhesives. We analyzed the results of 50 patients after radical excision of pilonidal sinus. 25 patients were treated by Molndal technique and 25 patients by the traditional technique of wound dressing. In the group treated by Molndal technique only 1 (4%) patient has revealed a wound infection, proven by positive microbiological examination and suppuration. In the traditional technique group 4 (16%) patients developed wound infection as inflammation and secretion as a sign of superficial infection. In the other group we analyzed the results of 50 patients after implantation of partial endoprosthesis after hip fracture. 20 patients were treated by Molndal technique and 30 patients by the traditional technique of wound dressing. In the group treated by Molndal technique no patient has revealed a wound infection (0%). In the traditional technique group 4 (13%) patients developed wound infection. All complication in both group were superficial incisional surgical infection (according to HPSC). There was no deep incisional surgical site infection or organ/space surgical site infection. Our results are clearly showing that Molndal technique is effective in preventing the postoperative wound infection.
