Efficacy of Different Adjuvants With Ropivacaine in Brachial Plexus Block on Anthroscopic Rotator Cuff Repair

Sponsor: Taipei Veterans General Hospital, Taiwan

Summary

The pain after shoulder rotator cuff repair surgery is severe due to the inflammatory reaction of tendon repair. Severe pain will reduce the patient's shoulder range of motion and delay functional recovery. The use of powerful analgesics for pain relief may also increase the chance of opiate analgesic-related side effects. Brachial plexus block with local anesthetic is widely used for pain control at the acute stage after shoulder arthroscopic surgery, but the maintenance time is often limited. Ropivacaine is a local anesthetic commonly used for brachial plexus block, and its half-life time is 11.8 hours. Clinical studies showed that using ropivacaine plus adjuvants such as dexamethasone or dexmedetomidine for brachial plexus block significantly extended the block duration, reduced postoperative pain, and reduced the use of opiate analgesics. However, the safest and most effective combination of local anesthetics remains unresolved. This trial aims to evaluate and compare the effects of brachial plexus block using dexamethasone and dexmedetomidine combined with ropivacaine on postoperative pain control and functional recovery after arthroscopic rotator cuff repair surgery.
