简要总结
This prospective randomized controlled study aims to compare the effects of interscalene block, infraspinatus-teres minor interfascial plane block, and a control group on postoperative analgesia and diaphragmatic function in patients undergoing shoulder arthroscopy. A total of 120 patients will be enrolled and allocated into three groups. Postoperative pain scores, opioid consumption, rescue analgesic requirements, and diaphragmatic function will be evaluated and compared among the groups. The study seeks to determine whether the infraspinatus-teres minor interfascial plane block can provide effective postoperative analgesia with less impact on diaphragmatic function compared with interscalene block.
详细描述
Shoulder arthroscopy is associated with significant postoperative pain. Interscalene block is widely used for analgesia but may impair diaphragmatic function because of phrenic nerve involvement. The infraspinatus-teres minor interfascial plane block has been proposed as an alternative regional anesthesia technique that may provide adequate analgesia while preserving diaphragmatic function. This randomized controlled trial will include 120 adult patients undergoing elective shoulder arthroscopy. Participants will be randomized into three groups: interscalene block, infraspinatus-teres minor interfascial plane block, and control. Pain scores, opioid consumption, time to first rescue analgesia, diaphragmatic excursion measured by ultrasound, and block-related complications will be recorded and analyzed.

结局指标
主要结局
Diaphragmatic Excursion
时间窗: 24 hours after surgery
Comparison of postoperative diaphragmatic excursion measured by ultrasonography between study groups.
Postoperative Pain Intensity
时间窗: 0, 2,4, 6, 12, and 24 hours after surgery
Postoperative pain intensity assessed using the Visual Analog Scale (VAS) , ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. higher scores indicate greater pain intensity. compared between study groups.
