PurposeAntibiotic administration within one hour prior to incision is a common quality metric; however, antibiotics are typically started at the time of diagnosis in pediatric patients with acute appendicitis. The purpose was to determine if antibiotic administration within one hour prior to incision reduces the incidence of surgical site infections (SSI) in pediatric patients with acute appendicitis started on parenteral antibiotics upon diagnosis.MethodsA retrospective review was performed of 478 patients aged 0-18years who underwent appendectomy for acute appendicitis from 7/2013 to 4/2015. Patients were categorized based on timing of antibiotic administration; there were 198 patients in Group A (<60min before) and 280 in Group B (>60min before).ResultsDemographics and operative time (A: 30.5±9.9 vs B: 30.8±12.2min, p=0.51) were similar. Procedures were performed laparoscopically and the groups had similar proportions of single-incision operations (A: 53% vs B: 55%, p=0.64). There was no difference in the incidence of superficial SSI (A: 2.0% vs B: 2.1%, p=1.0) or intraabdominal abscess (A: 4.0% vs B: 3.6%, p=0.81) and this remained true when stratified by intraoperative classification.ConclusionAntibiotic administration within one hour of appendectomy in pediatric patients with acute appendicitis who receive antibiotics at diagnosis did not change the incidence of postoperative infectious complications.Type Of StudyTreatment study.Level Of EvidenceIII.Copyright © 2017 Elsevier Inc.
