ClinConnect Summary

This clinical trial is studying a new method of pain relief for patients undergoing total hip replacement surgery, known as the low concentration local anesthesia fascia iliaca block (LCLA-FICB). The goal is to see if this technique can effectively reduce pain after surgery while allowing patients to maintain muscle strength, especially in the quadriceps, which is important for walking and mobility. Traditional methods can sometimes cause weakness in this muscle, making recovery more challenging. Researchers believe that using a lower concentration of local anesthetics will provide similar pain relief without the unwanted muscle weakness.

To be eligible for the trial, participants need to be adults over 21 years old who are scheduled for a primary hip replacement surgery and are in good physical health, as measured by the American Society of Anesthesiologists (ASA) scale. They should not have a history of substance abuse or certain medical conditions that would prevent them from receiving the nerve block. Participants can expect to receive the LCLA-FICB during their surgery and will be monitored for pain levels and muscle strength in the days following the procedure. This study aims to improve pain management while enhancing recovery, and it is currently recruiting participants.
