Brief summary

The goal of this study is to compare the efficacy of PVI irrigation to no irrigation for decreasing postoperative intra-abdominal abscesses in children with perforated appendicitis. Additionally, this study aims to verify the safety profile of dilute PVI for intra-abdominal irrigation.

Detailed description

Postoperative intra-abdominal abscesses are common occurrences after perforated appendicitis in pediatric patients despite utilization of evidence-based practices. Povidone-iodine is a commonly used antiseptic in surgical procedures and has been shown to be effective in reducing postoperative abscesses in adults with perforated appendicitis. This trial will be the first to rigorously test the efficacy of povidone-iodine irrigation in children and to verify its safety profile in this patient population.

Interventions

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.

PROCEDURENo irrigation

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

Inclusion criteria

* Children who undergo an appendectomy for perforated appendicitis. (Appendicitis: Diagnosis is made intraoperatively by the surgeon. Diagnosis Method: The visualization of a gross defect in the appendiceal wall or the presence of intraperitoneal stool or a fecalith at the time of operation.)

Exclusion criteria

* Patients presenting with simple or gangrenous appendicitis * Patients with a history of iodine sensitivity, thyroid disease or renal disease * Patients undergoing interval or incidental appendectomy * Patients/parents/legal guardians who are both non-English and non-Spanish speaking
