Respiratory Impact of LA Volume After IS Block

• Status: Recruiting
• Trial end date: 2022-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The hypothesis of this study is that a reduced extrafascial volume of local anesthetic for an interscalene brachial plexus block is associated with a lower incidence of diaphragmatic hemiparalysis after an arthroscopic surgery of the shoulder, without any reduction of the analgesic efficacy.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No
