Background and Aims: Both transversus abdominis plane (TAP) block and combined ilioinguinal-iliohypogastric (IIN/IHN) blocks are used routinely under ultrasound (USG) guidance for postoperative pain relief in patients undergoing inguinal hernia surgery. This study compares USG guided TAP Vs IIN/IHN block for post-operative analgesic efficacy in adults undergoing inguinal hernia surgery. Methods: Sixty adults aged 18 to 60 with American Society of Anesthesiologsts' grade I or II were included. After general anaesthesia, patients in Group I received USG guided unilateral TAP block using 0.75% ropivacaine 3 mg/kg (maximum 25 mL) and those in Group II received IIN/IHN block using 10 mL 0.75% ropivacaine. Postoperative rescue analgesia was with tramadol (intravenous) IV ± diclofenac IV in the first 4 h followed by oral diclofenac subsequently. Total analgesic consumption in the first 24 h was the primary objective, intraoperative haemodynamics, number of attempts and time required for performing the block as well as the postoperative pain scores were also evaluated. Results: Time to first analgesic request was 319.8 ± 115.2 min in Group I and 408 ± 116.4 min in Group II (P = 0.005). Seven patients (23.33%) in Group I and two (6.67%) in Group II required tramadol in first four hours. No patient in either groups received diclofenac IV. The average dose of tablet diclofenac was 200 ± 35.96 mg in Group I and 172.5 ± 34.96 mg in Group II (P = 0. 004). Conclusion: USG guided IIN/IHN block reduces the postoperative analgesic requirement compared to USG guided TAP block.
