ClinConnect Summary

This clinical trial is comparing two pain relief techniques, called the iliopsoas plane block (IPB) and the PENG block, for patients undergoing total hip replacement surgery. Both methods use a local anesthetic to help manage pain after surgery, but this study aims to see if they work equally well. A total of 118 adult patients who are scheduled for hip replacement will be randomly assigned to receive one of these two blocks before their surgery, and their pain levels will be monitored for 48 hours afterward.

To be eligible for this trial, participants must be adults over 18 years old, scheduled for hip replacement surgery, and have a general health status that is stable. People with certain conditions, such as pregnancy, chronic pain issues, or serious allergies to local anesthetics, will not be included. Participants can expect to receive standard pain relief after their surgery, and their recovery will be assessed through various measures, including how much pain they feel, how well they can walk, and their overall satisfaction with the recovery process. This study is important because if the IPB is found to be as effective as the PENG block, it could give doctors more options for managing pain and helping patients recover after hip surgery.
