Chlorhexidine vaginal wipes prior to elective cesarean section: does it reduce infectious morbidity? A randomized trial.

Objective: To evaluate the efficacy of preoperative vaginal cleansing using chlorhexidine 0.25% antiseptic wipes on rates of postcesarean section (CS) infectious morbidities (endometritis, febrile morbidity and wound infection).Methods: This prospective randomized trial was conducted among 218 pregnant women scheduled for term elective CS. Patients were equally divided into two groups by simple randomization. After spinal anesthesia and catheterization under aseptic technique, the study group had preoperative vaginal cleansing using chlorhexidine 0.25% antiseptic wipes for about 1 min, while the control group did not. All cases received the prophylactic antibiotics and the usual abdominal scrub. All participants received the routine postoperative care without other interventions. Adverse postcesarean infectious morbidities such as endometritis, febrile morbidity and wound infection were observed at the time of hospital discharge and weekly for 6 weeks postpartum.Results: Both groups were matched regarding the baseline patients' characteristics (age, gestational age, BMI, operative time and postoperative hospital stay). Overall, post-CS infectious morbidity were significantly reduced from 24.4% in the control group to 8.8% in the intervention group; p value <0.05. Marked reduction was seen in the incidence of endometritis (13.2% in the control group versus 2.9% in the intervention group; p value <0.05). However, fever and wound infection showed no significant difference between both groups.Conclusion: Cleansing the birth canal with chlorhexidine 0.25% wipes prior to elective CS appears to be effective in reducing rates of post-CS infectious morbidity mainly endometritis.
