Comparison of Continuous vs. Single-injection Interscalene Block on Quality of Recovery in Outpatient Arthroscopic Rotator Cuff Surgery

What this Trial Is About

Researchers are comparing two methods of pain control called single-injection interscalene block and continuous interscalene block in patients undergoing outpatient arthroscopic rotator cuff repair surgery. This study evaluates which method provides better quality of recovery by measuring pain and other recovery factors after surgery. The study is randomized and triple-blinded to ensure reliable comparison between the two techniques. Participants will be randomly assigned to receive either a single injection of anesthetic or a continuous infusion via a catheter with an elastomeric pump. The continuous infusion group will have a set infusion rate of 4 ml per hour with additional boluses available every 30 minutes, while the single-injection group will receive no continuous infusion but can use the bolus option for pain relief. Both groups will be monitored closely during the first three days after surgery. During the study, participants will be contacted by telephone for surveys assessing their recovery quality, pain levels, opioid use, and any complications. They will also have follow-up care by the Acute Pain Unit for the first three days. The main outcome measured is the daily Quality of Recovery-15 (QoR-15) score over three postoperative days. Additional measures include opioid consumption, pain scores, rates of additional consultations or readmissions, and use of rescue analgesics. Participation lasts through the immediate postoperative period with detailed monitoring to assess recovery.
