Objectives: The purpose of the study is to evaluate the effectiveness of ilioinguinal –iliohypogastric nerve block in post operative analgesia in patients undergoing inguinal herniorraphy Methods: Inguinal herniorraphy was carried out under spinal anaesthesia. Subsequently 60 patients belonging to ASA physical status I and II were randomized into 2 groups of 30 each. Group B received landmark based ilioinguinal / iliohypogastric nerve block using 0.75% ropivacaine 14 ml to the same half of the surgical side while Group C received the same volume of normal saline. Results: Excellent post operative pain relief was afforded in subjects receiving ilioinguinal /iliohygastric nerve block (Group B) for up to 4 hours post – operatively. The time to rescue analgesia was also prolonged in the study group as compared to the control group 9.5 hours versus 5.42 hours. The cumulative dose of analgesic consumed was also less in the study group as compared to control group 25 mg versus 72.5mg. Conclusion: Pre-incisional Ilioinguinal, Iliohypogastric nerve blocks with 14 ml (0.75%) ropivacaine along with spinal anesthesia is effective in managing pain following inguinal hernia repair. It is evident from our study that this technique significantly reduces postoperative pain perception and analgesic requirement.
