Clinical Trial Summary

It is proposed to investigate the effectiveness of ultrasound-guided intertrochanteric block of the infraspinatus minor round myofascial block not inferior to the interosseous groove brachial plexus nerve block in postoperative analgesia and overall quality of recovery in shoulder surgery.


Clinical Trial Description

Intersulcus brachial plexus nerve block is considered to be the best method for pain nerve block after shoulder joint surgery. It can not only effectively reduce the postoperative pain and discomfort of patients, but also reduce the intraoperative demand for opioids. However, the use of intermuscular brachial plexus block should be prohibited when the patient has a clotting disorder or is taking anticoagulant drugs, has a local infection or a systemic infection. There may also be anesthesia risks such as nerve damage, vascular damage, respiratory depression, and diaphragmatic paralysis with dyspnea. Infraspinatus-teres minor (ITM), first proposed by Shin Hyung Kim, is a single-site injection in the interfascial plane between Infraspinatus and teres minor. Once the IS and Tm on the humeral head area are identified, by moving the probe mediocaudally, the interfascial structure of the IS and Tm can be traced along the glenohumeral joint, scapular neck area. On autopsy, local anesthetics were found to have spread to the suprascapular and axillary nerves. This result suggests that interfascia block injection of local anesthetics between the infraspinatus and teres minor muscles may help relieve pain in the upper shoulder, back, and external sensory areas. At present, there are few clinical reports on the use of infraspinatus-teres minor interfascial block for postoperative analgesia of shoulder joint, and the postoperative analgesia effect is only reported in individual cases, without comparison with other nerve blocks There are few studies on the clinical application of ITM block, but ISB has become the best method for postoperative analgesia of shoulder joint surgery. the investigators designed a prospective, randomized controlled, non-inferior study to investigate the efficacy of ultrasound-guided subaspina-teres minor interfascial block in analgesia and overall quality of recovery after shoulder joint surgery. The primary outcome indicator was the area under the NRS curve at rest in the 0-24h postoperative period ;
