Onset and Recovery of Ultrasound Guided Out-of-plane Versus In-plane Interscalene Block in Arthroscopic Shoulder Surgery

• Status: Completed
• Trial end date: 2019-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The aim of this study was to assess the out-of-plane versus the in-plane approaches for the interscalene brachial plexus block; as regards the performance time, the onset, the progression and the recovery of sensory block, the onset and progression of the motor block as well as, the postoperative pain score and the duration of analgesia for arthroscopic shoulder surgery. A total of 60 patients of American Society of Anesthesiologists (ASA) physical status I-II were randomly divided to receive either the in-plane approach (Group I), or the out-of-plane approach (Group O).
