Summary

Surgical site infections (SSIs) constitute an important medical and socioeconomic problem worldwide. Despite the fact that the risk factors for SSIs were identified and the continuously increasing medical knowledge in the fields of tissue engineering, molecular biology and microbiology facilitated the development of numerous new recommendations and methods for management, in many cases the available options for successful treatment of post-operative wound infections remain limited. Non-treated or inappropriately treated SSIs often lead to necrosis of the surrounding tissues, wound dehiscence, formation of fistulas, or become sites of origin for systemic infections. Patients are exposed to risk of further complications and hospitalization time extends resulting in increased total treatment costs. Treatment prolongation affects also the quality of life and psychosocial functioning of patients with impaired wound healing. Considering the arguments above, appropriate prevention and management of infected post-surgical wounds is currently one of the priorities for the majority of invasive medical disciplines. Obstetrics constitute a field of medicine in which the issues associated with wound healing are particularly relevant. According to the literature data wound infections occur in approximately 1.8-11.3% of women undergoing caesarean section. Dialkylcarbamoyl chloride (DACC) is a fatty acid derivative that irreversibly binds microorganisms to the dressing fibres as a result of hydrophobic interaction. As the mechanism of DACC action is solely physical no chemical agents are released into the wound bed and the dressing could be safely used by women during puerperal period. The purpose of this randomized controlled study is to compare the effect of DACC impregnated dressing and standard surgical dressing in the prevention of SSIs in adult women following caesarean section. This study will also evaluate pre-, peri- and postoperative risk factors of SSIs and analyze health economics of DACC impregnated dressings for prevention of post-cesarean wound infections.

Detailed description

This is a single-blinded randomized controlled trial performed at the Department of Obstetrics and Gynecology of Medical University of Warsaw. The study will involve 518 patients undergoing caesarean section who after giving their informed consent will be randomly divided into two groups: study (n=259) and control group (n=259). The study group will receive DACC impregnated dressing - Sorbact Surgical Dressing ® (ABIGO Medical AB, Sweden) and the control group will receive standard surgical dressing. In all participants transverse skin incision and low transverse uterine incision will be performed during caesarean section procedure. All participants will receive prophylactic dose of antibiotics prior to the start of surgery (1g cefazolin intravenously 0-30 minutes before surgery) and wound irrigation with octenidine prior to the subcutaneous tissue closure. For fascial incision, subcutaneous tissue and skin incision closure continuous antibacterial braided absorbable suture, single monofilament absorbable suture and subcuticular continuous monofilament non-absorbable suture will be used, respectively. Dressing will be left in place for the first 48 hours post caesarean section unless clinical reason exists to replace it. After the first 48 hours postoperatively all of the dressings will be removed and first wound evaluation will be performed. On post-operative day 3 patients will be discharged and indicated to revisit on post-operative day 7 to remove the skin suture. During this follow-up visit second wound review will be performed for any signs of infection. Third, and final wound assessment will take place on post-operative day 14. To analyze overall treatment costs patients with SSI will be followed up until the end of treatment, up to 8 weeks post surgery.
