In plain words

What the trial is, and whether it could suit you

Background: In recent years, regional anesthesia has become more popular because it can reduce pain and the need for strong pain medications like morphine. For hip surgery, the PENG block is already known to be effective. A newer method, called the iliopsoas plane block (IPB), is very similar and has also shown good results in hip arthroscopy. However, these two techniques have never been directly compared in patients undergoing hip replacement surgery using the posterior approach. Goal: This study aims to see if the IPB is just as effective as the PENG block for controlling pain and helping patients recover well after hip replacement surgery. Method: 118 adult patients scheduled for hip replacement under spinal anesthesia will be randomly assigned to receive either: IPB: 7 ml of Ropivacaine 7.5 mg/ml PENG: 14 ml of Ropivacaine 3.75 mg/ml Both injections are given under ultrasound g
