Chlorhexidine-alcohol significantly reduced surgical-site infections after cesarean delivery compared to iodine-alcohol. This study provides evidence for improved preoperative skin antisepsis in obstetric procedures.
Area of Science:
- Obstetrics and Gynecology
- Infectious Disease Prevention
- Surgical Safety
Background:
- Surgical-site infection (SSI) is a risk in cesarean delivery, the most common U.S. surgery for women.
- Limited evidence exists to guide antiseptic choice for cesarean skin preparation.
- Effective preoperative skin antisepsis is crucial for reducing SSI risk.
Purpose of the Study:
- To compare the efficacy of chlorhexidine-alcohol versus iodine-alcohol for preoperative skin antisepsis.
- To determine if chlorhexidine-alcohol is superior to iodine-alcohol in preventing SSIs after cesarean delivery.
Main Methods:
- Single-center, randomized controlled trial involving 1147 patients undergoing cesarean delivery.
- Patients were assigned to skin preparation with either chlorhexidine-alcohol or iodine-alcohol.
- Primary outcome: superficial or deep SSI within 30 days, defined by CDC criteria.
Main Results:
- Surgical-site infection occurred in 4.0% of the chlorhexidine-alcohol group vs. 7.3% of the iodine-alcohol group (RR 0.55, P=0.02).
- Lower rates of superficial and deep SSIs were observed with chlorhexidine-alcohol, though not all differences reached statistical significance.
- Adverse skin reactions were comparable between the two antiseptic groups.
Conclusions:
- Chlorhexidine-alcohol use for preoperative skin antisepsis significantly lowered the risk of surgical-site infection following cesarean delivery.
- Results support the use of chlorhexidine-alcohol over iodine-alcohol for cesarean delivery skin preparation.
- This finding has implications for improving surgical safety in obstetric procedures.
