MRI of axillary brachial plexus blocks: a randomised controlled study.

ABSTRACT:

Background

Axillary plexus blocks are usually guided by ultrasound, but alternative methods may be used when ultrasound equipment is lacking. For a nonultrasound-guided axillary block, the need for three injections has been questioned.

Objectives

Could differences in block success between single, double and triple deposits methods be explained by differences in local anaesthetic distribution as observed by MRI?

Design

A blinded and randomised controlled study.

Setting

Conducted at Oslo University Hospital, Rikshospitalet, Norway from 2009 to 2011.

Patients

Forty-five ASA 1 to 2 patients scheduled for surgery were randomised to three equally sized groups. All patients completed the study.
