• Total Enrollment: 44 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2015-05-31
• Study Completion Date: 2015-08-31

Brief Summary

The achievement of peripheral nerve block requires several needle passes, with each of them being at risk of causing nerve injury either by direct trauma or intraneural injection even with the use of the ultrasound.

The ultrasound guided supraclavicular brachial plexus block is known to be at risk of pneumothorax and / or nerve injury.

This study is designed to determine the maximal effective distance away from the nerve for the injection to be effective.

Conditions
