No results posted yet for this study

Summary

The objective of this study is to compare the clinical effectiveness in producing anesthesia of the whole upper limb between two regional blocks - Selective Trunk Block (SeTB) and Hybrid Interscalene Supraclavicular Brachial Plexus Block (hybrid IS-SC BPB).

PROCEDURE

Selective Trunk Block

It is one type of peripheral nerve blocks for upper extremity surgery. Patients will have an ultrasound scan and nerve block with local anesthetic (LA) agent (a mixture of 2% Xylocaine with 1:200,000 adrenaline and 0.5% Chirocaine in a total of 20ml) injected at the trunks of the brachial plexus in order to produce the anesthesia of the whole upper extremity of the patients scheduled for upper limb surgery. SeTB will be performed as a "two-injection technique". One at the side of the neck (interscalene groove) of the affected upper limb, injections will be made near the superior trunk (5mL) and follow by redirection of the needle under ultrasound guidance to inject the LA to middle trunk (5mL). Then the second skin puncture will be made near the upper part mid-collar bone (supraclavicular fossa) to inject the LA to the inferior trunk (10mL).

PROCEDURE

Interscalene-Supraclavicular Brachial Plexus Block (IS-SC BPB)

It is another type of peripheral nerve blocks for upper extremity surgery. Patients will have an ultrasound scan and nerve block with local anesthetic (LA) agent (a mixture of 2% Xylocaine with 1:200,000 adrenaline and 0.5% Chirocaine in a total of 30ml) injected at the interscalene groove and supraclavicular fossa, so "two-injection technique" will be adopted. The first skin puncture will be near the side of the neck (interscalene groove) of the affected upper limb (15mL) and then the second skin puncture will also be made near the upper mid-collar bone (supraclavicular fossa) to inject 15mL of LA.
