简要总结
This randomized interventional study compares the analgesic efficacy of Adductor Canal Block combined with Infiltration of the Posterior Capsule of the Knee (IPCAK) versus the 4-in-1 block technique in patients undergoing knee surgery. Twenty-four patients were randomly allocated into two equal groups. The primary objective is to compare postoperative pain scores and analgesic requirements. Secondary outcomes include time to first rescue analgesia, total analgesic consumption, motor function preservation, and block-related complications.
详细描述
Effective postoperative pain control following knee surgery is essential for early mobilization, rehabilitation, and patient satisfaction. Several regional anesthesia techniques have been developed to provide analgesia while preserving quadriceps muscle strength. Adductor Canal Block combined with Infiltration of the Posterior Capsule of the Knee (IPCAK) has been proposed as a motor-sparing technique that provides effective anterior and posterior knee analgesia. The 4-in-1 block is another ultrasound-guided regional anesthesia technique designed to provide comprehensive analgesia for knee surgery.
This prospective randomized interventional study enrolled 24 patients undergoing knee surgery. Participants were randomly assigned to receive either Adductor Canal Block with IPCAK or the 4-in-1 block. Postoperative pain scores, time to first rescue analgesia, total analgesic consumption, motor function, patient satisfaction, and complications were evaluated and compared between the two groups
