IPACK block with spinal anesthesia compared to fentanyl-based spinal anesthesia for postoperative analgesia following arthroscopic meniscectomy: a randomized, prospective study

Abstract Background Local anesthesia and intrathecal narcotics are utilized to provide postoperative analgesia. IPACK (infiltration between the knee capsule and popliteal artery) is a new localized analgesic approach for knee surgery. This randomized study aimed to compare fentanyl-based spinal anesthesia and IPACK block-based spinal anesthesia for postoperative analgesia in patients undergoing arthroscopic meniscectomy. Results In group F, the VAS (visual analog scale) was higher than in group I, whereas the total amount of morphine was lower in group I (P
