Axillary Plexus Block in a high resolution MRI-results from 9 pilots

In MD Trygve Kjelstrup's research magnetic resonance imaging (MRI) proved beneficial for presenting anatomy for regional anaesthesia and to demonstrate spread of local anaesthetic. A new axillary plexus block with a triple injection combining a short axillary catheter method with a transarterial axillary block was evaluated with a 3 Tesla MRI. Three different block techniques were investigated comparing the clinical efficacy of the techniques with the MR findings.
Clinical High Field MRI (3T) scanner simplified the recognition of brachial plexus nerves in the axilla. After injection of local anaesthetic (LA), the identification of the nerve structures was nevertheless difficult. When all nerves were surrounded of LA in the axilla (MRI), it seemed to be associated with a clinical complete brachial plexus block. The final study will give more information.
