Effect of Remote Local Peripheral Nerve Cooling on Pain of Arterial Puncture
The Second Affiliated Hospital of Chongqing Medical University
100 participants
Feb 15, 2025
INTERVENTIONAL
Conditions
Summary
In this project, volunteers will be recruited to cool the superficial skin of the axillary brachial plexus away from the puncture point, resulting in local peripheral nerve cooling, and observe its impact on the pain of arterial puncture.To explore the local peripheral nerve cooling treatment can produce controllable and reversible analgesic effect even if away from the wound, and provide a new nonpharmaceutical analgesic mode for clinical.
