Postoperative analgesics were administered on request and selected based on pain severity.MeasurementsPain scores, analgesic drug requirement, and side effects were observed for 24hours.Main ResultsPostoperative pain scores were lower in TAP group compared to INF group (P<.001). Analgesic consumption was significantly higher at the 5th minute and 1st, 6th, and 12th hours in the INF group (P<.001). The frequency of additional analgesic use in home and the total analgesic used during the postoperative 24hours were significantly higher in INF group (P<.001). Side effects were lower in the TAP group. Parent's satisfaction scores were higher in TAP group.ConclusionTransversus abdominis plane block is effective method with convenient technique, drug dosage, and volume in pediatric patients undergoing inguinal hernia surgery.Copyright © 2016 Elsevier Inc.
