The primary objective of this study is to evaluate and compare the efficacy of different volumes of local anesthetics, administered at the same total dose, for ilioinguinal and iliohypogastric (II/IH) nerve blocks in patients undergoing unilateral inguinal hernia repair.
The investigators aim to determine whether varying the injectate volume-while keeping the total drug amount constant-influences the quality and duration of postoperative analgesia. By monitoring pain scores and opioid consumption, this research seeks to identify the optimal volume-to-dose ratio for enhancing patient recovery and pain management following inguinal surgery.
