ClinConnect Summary

This clinical trial is investigating a new way to help reduce pain during a medical procedure called arterial puncture, which involves taking blood from an artery. The study will look at whether cooling the skin over certain nerves, located away from the puncture site, can lessen the pain felt during this procedure. This method aims to provide a non-drug approach to pain relief, which could be beneficial for patients undergoing various medical treatments.

To participate in the trial, volunteers must be between 18 and 65 years old, right-handed, and have a normal test indicating good blood flow in their hands. They should not have any serious medical conditions or a history of substance abuse, and they should not be taking pain medications before or during the study. The trial is not yet recruiting participants, but those who are eligible will have the opportunity to contribute to important research that could lead to better pain management options in the future.
