Intermittent Compression Maneuver of Upper Arm to Reduce Axillary Brachial Plexus Block Onset Time

Not Applicable

• Conditions: Forearm Injuries; Hand Injuries
• Interventions: Procedure: Ultrasound guided axillary plexus block; Procedure: Intermittent pneumatic compression maneuver

• Registration Number: NCT04056585
• Lead Sponsor: Catholic Kwandong University

Brief Summary

This study evaluates the addition of intermittent pneumatic compression maneuver to axillary brachial plexus block in forearm and hand surgery. Half of participants will receive axillary brachial plexus block and intermittent pneumatic compression maneuver, while the other half will receive only axillary brachial plexus block.
