Nerve Block Clinical Trial
Official title:
Regional Changes in Upper Limb Perfusion Following Brachial Plexus Block: A Pilot Study
Ultrasound-guided regional anesthesia is increasingly being used in the modern surgical
environment to provide specific intraoperative anesthesia and postoperative analgesia.
Infiltration of local anesthesics around peripheral nerves firs blocks sympathetic, then
sensory, then motor nerve function. Sympathectomy-induced vasodilation following brachial
plexus block results in increased skin temperature and arterial flow within minutes.
Although it has not been shown to reliably increase diameter or cross-sectional area of
distal arteries, brachial plexus block does change the pattern and quantity of blood flow to
the hand. Given that the magnitude of change of flow cannot be attributed to vessel radius,
the investigators suspect that the more laminar fluid dynamics are due to vascular tone.
The investigators study aims to quantify alterations in physiology and peripheral
vasodilator response. The investigators anticipate that axially block will significantly
improve regional blood flow.
