NCT01033006

Brief Summary

Background and aims: Magnetic resonance imaging (MRI) has proved beneficial for presenting anatomy for regional anaesthesia and to demonstrate spread of local anaesthetic. A new axillary plexus block with a triple injection (1), combining a short axillary catheter method with a transarterial axillary block, is now being evaluated with a 3 Tesla MRI. In this study, the investigators are investigating MR visualisation of three different block techniques and compare the clinical efficacy of the techniques, with the MR findings. Patients \& Methods: After obtaining approval of the protocol from the regional ethical committee, 3 x 15 adult patients, scheduled for hand surgery, were included in a randomised, blinded prospective study.
