Clinical Trial Summary

The intercostobrachial nerve underlies many anatomical variations. For surgery of the upper arm the axilla is usually not anaesthetized by a brachial plexus block, which therefore needs to be completed by an intercostobrachial nerve block. The optimal access for an ultrasound guided block of the intercostobrachial nerve is not yet known. The investigators compare a proximal and a more distal approach to the nerve referred to onset time, sensory blocked area and duration.

Description:

The participants will be randomized into two groups:

Group one receives a modified PECS 2 (thoracic wall) block above the second intercostal space with injection between the Musculus serratus anterior and Musculus pectoralis minor.

Group 2 receives a subpectoral block under the pectoralis major muscle at the medial boarder of the axillary triangle.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Blocked area in squared cm	Area of sensory loss to pin prick test	Assessment 30 minutes after intervention
Secondary	Block onset time in minutes	Onset time of complete analgesia. Assessment by pin prick test in the middle of the axilla	Complete timeframe of 45 minutes with testing every 5 minutes
Secondary	Block duration in minutes	Complete analgesia to pin prick in the middle of the axilla	Assessment every 30 minutes for 8 hours after nerve block
