Preoperative vaginal preparation with povidone-iodine on post-caesarean infectious morbidity.

The commonest complication associated with caesarean section is infection. The aim of this study is to investigate the effect of vaginal preparation with povidone-iodine on post-caesarean infection. In this clinical trial, 568 patients were selected for two groups: a treatment group and a control group, each with 284 patients. A vaginal scrub was performed before the routine abdominal scrub, with two 4 × 4 cm sponge sticks saturated with povidone-iodine solution, rotated in the vagina for about 30 s. In the control group, only the abdominal scrub was performed. Patients received a single dose of prophylactic antibiotics, and were reviewed for 6 weeks to look for predefined variables. Post-caesarean endometritis occurred less frequently in the treatment group than in the control group (2.5% vs 1.4%). There was no significant difference for febrile morbidity and wound infection in the two groups. The adjusted odds ratio for endometritis after vaginal preparation was 0.03 (95% CI: 0.008-0.7). Vaginal preparation with povidone-iodine may decrease the risk of post-caesarean endometritis.
