Dilute Povidone-iodine Irrigation vs No Irrigation for Children With Acute, Perforated Appendicitis

"Povidone-iodine (PVI) is an antiseptic solution consisting of polyvinylpyrrolidone with water, iodide, and 1% available iodine. It has bactericidal ability against a large array of pathogens, including those pathogens which commonly cause postoperative IAA in children with perforated appendicitis.~1% PVI will be used. Once the appendix has been removed and hemostasis ensured, the surgeon will perform the irrigation with 10cc/kg (minimum 100ml and maximum 1000ml) of 1% PVI. After completing the irrigation, the surgeon will suction out all intra-abdominal fluid into a suction canister."

Patients allocated to the control group will not undergo intra-abdominal irrigation.
