ClinConnect Summary

This clinical trial is investigating two different techniques for providing pain relief after surgery using regional anesthesia, specifically focusing on how well each technique targets specific areas of the body. The two methods being compared are called the Erector Spinae Plane (ESP) block and the Intertransverse Process (ITP) block. Both techniques aim to numb the chest wall but do so in slightly different ways. The researchers want to see how well each method works in healthy adults by testing the areas of skin that become numb after receiving these blocks.

To be eligible for the study, participants must be at least 18 years old and able to give written consent. They should be in generally good health, without certain medical conditions that could complicate the procedure. Participants will receive both types of blocks on different days, with at least a week in between, and they will undergo tests to assess how well each block works. The study aims to ensure that both techniques are safe and to gather information about how the medication used (lidocaine) is absorbed in the body.
