Diluted Aqueous Povidone-Iodine Compared to Saline to Decrease Surgical Site Infections

"Peritoneal lavage: With the fascia open, the peritoneum will be washed out with 1L of dilute aqueous povidone-iodine solution allowing the solution to sit in the peritoneum for 2 minutes. This is followed by suctioning of the povidone-iodine solution then wash-out with 2L of normal saline followed by suctioning of the normal saline.~Wound Irrigation: With the fascia closed, the wound will be irrigated with 500mL povidone-iodine solution, suctioned, then washed-out with 500 mL normal saline."
