**6.2 Surgical site preparation**

Povidone-iodine or chlorhexidine can be used for surgical site preparation. There is evidence suggesting the superiority of chlorhexidine, but these findings do not specifically pertain to postpartum hemorrhage surgery. It is known that the recovery of vaginal flora is parallel to vaginal cuff infections. Vaginal recolonization occurs more rapidly with chlorhexidine compared to povidone-iodine. Therefore, chlorhexidine can be used to reduce the risk of postoperative surgical site infections in these cases.
