Abstract

The aim of the study was to compare the rate of postoperative rebound pain of a single injection brachial plexus block method compared with a continuous catheter infusion block method in patients undergoing arthroscopic shoulder surgery. 60 patients with selective shoulder arthroscopy surgery were randomly divided into 2 groups of brachial plexus blockade under ultrasound guidance: 1 group received a single dose of local anesthetic and 1 group with a catheter continuously infusionat the Center for Anesthesiology and Surgical Intensive Care – Viet Duc Hospital from April to August 2021. Time of occurrence and rate of rebound pain, pain severity at rest and the amount of morphine consumed was recorded 72 hours after surgery. There were 4/30 patients in the single shot group experienced rebound pain (13.33%) and statistically significantly higher than the continuous catheter infusion group (p <0,05). The average amount of morphine used in the continuous infusion group was statistically significantly lower with p < 0.05. Our study showed that continuous catheter-guided brachial plexus block was effective in reducing the incidence of postoperative rebound pain in shoulder arthroscopy patients.
