Clinical Trial: Effect of Optimal Biological Volume Bupivacaine Liposome Interscalene Brachial Plexus Block on Postoperative Analgesia After Shoulder Arthroscopy

U.S., Aug. 29 -- ClinicalTrials.gov registry received information related to the study (NCT07792044) titled 'Effect of Optimal Biological Volume Bupivacaine Liposome Interscalene Brachial Plexus Block on Postoperative Analgesia After Shoulder Arthroscopy' on Aug. 23.

Brief Summary: This study aims to evaluate whether 15ml/75mg low-dose bupivacaine liposome is non-inferior to 15ml/133mg standard-dose bupivacaine liposome for postoperative analgesia in interscalene brachial plexus block during arthroscopic shoulder surgery, through a single-center, prospective, double-blind, non-inferiority randomized controlled clinical trial. It will also assess whether 15ml/75mg low-dose bupivacaine liposome is superior to 15ml/133mg standard-dose bupivac...
