Use of a single-dose interscalene block and general anesthesia during arthroscopic rotator cuff repair effectively relieved pain without any complications, according to results of this study.
Researchers randomly assigned 62 patients with rotator cuff tears to be treated with either a single-dose interscalene block and general anesthesia or general anesthesia alone. Researchers measured preoperative pain scores on the day of surgery, at 1 hour and 6 hours postoperatively and then every 6 hours until 3 days postoperatively. Researchers also evaluated the stress biomarkers insulin, dehydroepiandrosterone sulfate and fibrinogen preoperatively on the day of surgery and postoperatively at 18 hours, 42 hours and 66 hours through blood sampling.
