TRANSVERSE ABDOMINAL PLANE BLOCK VS. ILIO-INGUINAL ILIO-HYPOGASTRIC BLOCK in PEDIATRIC INGUINAL SURGERY

The study aimed to compare the analgesic effect of ultrasound-guided transverse abdominal plane (TAP) block to ilio-inguinal ilio-hypogastric (IIIH) nerve block in children after inguinal surgery. This prospective, randomized study included children aged six months to twelve years, classified as ASA I or II, scheduled for elective unilateral inguinal surgery. Participants received either a TAP block or an IIIH block with bupivacaine following standardized induction of general anesthesia. Analgesics were not systematically administered post-induction. Postoperative pain was monitored for six hours in the hospital, and if the CHEOPS score exceeded 7, paracetamol was administered, with nalbuphine as a secondary option if needed. At home, parents assessed pain using the PPMP score, administering paracetamol and ibuprofen if necessary. Primary outcomes included postoperative analgesia quality, determined by time to first analgesic requirement and the need for analgesics at hospital and home. Secondary outcomes measured included block performance duration, parental satisfaction, and incidence of complications.
