In this study the investigators would like to show that when patients undergo upper limb
surgery under supraclavicular brachial plexus block, additional blocking of the
Intercostobrachial Nerve Block (ICBN) does not affect the incidence or course of tourniquet
pain.
surgery under supraclavicular brachial plexus block, additional blocking of the
Intercostobrachial Nerve Block (ICBN) does not affect the incidence or course of tourniquet
pain.
The ICBN is a cutaneous sensory nerve that supplies the medial aspect of the upper arm.
Traditionally this nerve is blocked to alleviate tourniquet pain. The etiology of tourniquet
pain is complex and the study team hypothesize that blocking the ICBN has no impact on
tourniquet pain. Patients will receive a supraclavicular block and be divided into two
groups; ICBN with local anesthetic or ICBN with saline. All patients in this study will
receive a supraclavicular block as their primary anesthetic and then be divided into two
groups; those who receive ICBN and those who do not. Amount of intraoperative analgesics,
conversion to deep sedation or general anesthesia, and onset of time to tourniquet pain will
be the primary measures of this study.
