NCT02714738

Brief Summary

The purpose of this study is to determine whether the incidence of tourniquet pain is decreased if infraclavicular nerve block is administered, compared to axillary brachial plexus block, for surgical interventions at the level or distal to the elbow.

Study Arms (2)

Infraclavicular Block

EXPERIMENTAL

The patient will be positioned supine. The operating limb may be positioned abducted or adducted by side depending on operator preference and patient factors. After standard preparation, the needle will be directed towards the target area using an in-plane, short-axis technique. Local anaesthetic (lidocaine 2% with epinephrine 1:200.000) will be injected posterior to the artery with the intention achieving the U shape, cranio-postero-caudal spread. Local anaesthetic will be deposited to the lateral and medial cords as well, if required. The total dose of the local anaesthetic will be 20-30 ml, as clinically indicated.

Procedure: Ultrasound guided peripheral nerve block

Axillary Brachial Plexus Block

EXPERIMENTAL

The patient will be positioned supine with the operative upper limb extended, flexed at the elbow, rested on a pillow to expose the axilla. After standard preparation, the needle will be directed towards the target area using an in-plane, short-axis technique. All four nerves in the axillary region are being blocked. The local anesthetic (lidocaine 2% with epinephrine 1:200.000, 15-25 ml) will be divided among the four nerves as clinically indicated by the spread, but at least 3 ml applied to each nerve.

Procedure: Ultrasound guided peripheral nerve block
