Summary

Brachial plexus block (BPB) is frequently used as the sole anesthestic technique for upper extremity surgery. However, the choice of injection can be made from different approaches that often depends on the site of surgery because the extent of sensory-motor blockade after a BPB varies with the approach used. The investigator is not aware of any single BPB technique that can consistently produce surgical anaesthesia of the whole ipsilateral upper extremity. However, occasionally surgery entails that the whole upper extremity is anesthetized, i.e. from the shoulder to the elbow, or even the forearm, wrist or hands. This clinical challenge has been addressed previously using a combination of BPB techniques. The investigator has recently demonstrated that it is feasible to accurately identify majority of the main components of the brachial plexus above the clavicle, including the three trunks, using ultrasound imaging. Since majority of the innervation of the upper extremity, i.e. shoulder, arm, elbow, forearm, wrist and hand, originates from the three trunks of the brachial plexus, the investigator hypothesized that selectively blocking upper, middle, and inferior trunks of the brachial plexus will produce surgical anesthetsia of the whole ipsilateral upper extremity. The aim of this study is to assess a novel brachial plexus block technique, the selective trunk block (SeTB), and provide preliminary clinical evidence of its effectiveness in producing surgical anesthesia of the whole ipsilateral upper extremity.

PROCEDURE

Selective Brachial plexus Block

It is one type of peripheral nerve blocks for upper extremity surgery. In this study, the block will be done under the ultrasound guidance and the local anesthetic agent (a mixture of 2% Xylocaine with 1: 200,000 adrenaline and 0.5% Chirocaine in a total of 25ml) will be injected at the trunks of the brachial plexus in order to produce the surgical anesthesia of the whole upper extremity of the patients scheduled for upper limb surgeries.
