Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Total hip arthroplasty (THA) is one of the main elective orthopedic surgery. Recent studies have proven that patients undergoing an elective THA who are part of a fast track surgery program including an opioid free anesthesia (OFA) presented a decrease of mortality and a reduced in-hospital length of stay. Based on the anatomical knowledges, the Quadratus Lumborum Block seems to be an interesting locoregional technique for patients undergoing THA. So far, there is no recommanded locoregional aesthesia in this indication. The investigators hypothezised that QLB would give an efficient analgesia in the 24h following a THA.

Therefor, the study performed a prospective, randomized, double blind trial in the Nice Universitary hospital of Pasteur 2 and in Arnault Tzanck Institute among all patients who underwent THA, comparing a QLB using ropivacaïne 2mg/ml 20ml vs isotonic saline solution 20 ml.The main end-point is the decrease opiod consumption in the 24h following THA.
