 To determine the effectiveness once-daily administration, a randomized controlled trial RCT will be conducted to compare outcomes between the two treatment schedules. We will recruit 100 patients 50 per treatment aged 5-18 being surgically treated for perforated appendicitis at the Childrens Hospital of Eastern Ontario, who will be randomly assigned to one of the two treatment schedules. To compare the efficacy of the treatments, outcomes such as duration of hospital stay and theoretical cost will be measured and analyzed using statistical tests.
