ClinConnect Summary

This clinical trial is studying how smoking affects the time it takes for a specific type of anesthesia, called an ultrasound-guided infraclavicular brachial plexus block, to work during hand or forearm surgery. The trial will involve 40 patients aged 18 to 65 years who are either non-smokers or smokers who smoke at least 20 cigarettes a day for over a year. The goal is to see if smokers experience different onset times and durations of pain relief compared to non-smokers.

To participate in the trial, individuals must be in good health (classified as ASA physical status I or II) and scheduled for surgery on their hand or forearm. However, those with certain medical conditions, such as severe obesity, bleeding disorders, or allergies to local anesthetics, will not be eligible. Participants can expect to receive the anesthesia through a guided technique that uses ultrasound to ensure accuracy, and their pain levels will be monitored for 24 hours after surgery. This study aims to better understand how smoking impacts pain management during and after surgery.
