Caissutti C, et al. – A systematic review and meta–analysis are performed to evaluate the effectiveness of vaginal cleansing before cesarean delivery in decreasing postoperative endometritis. The current study shows that vaginal cleansing immediately before cesarean delivery in women in labor and in women with ruptured membranes decreases the risk of postoperative endometritis. They suggest preoperative vaginal preparation before cesarean delivery in these women with sponge stick preparation of povidone–iodine 10% for at least 30 seconds because it is generally inexpensive and a simple intervention. More information is needed to evaluate whether this intervention may be also helpful for cesarean deliveries performed in women not in labor and for those without ruptured membranes.
