After complete hyparthroplasty, postoperative discomfort is a significant issue. In these patients, many methods are often utilised in postoperative analgesia, including neuraxial analgesia, intravenous analgesia and peripheral neuron blocks. The benefit of peripheral nerveblocks is phytosanitary treatment, reduced engine impairment and fewer systemic effects. Common peripheral blocks of nerve for hip operations include suprainguinal fasciailiacablock(FIB) and lumbar plexusblock. The Quadratus lumborum block (QL) is a newly designed lower abdominal and hip chirurgical block with high performance. Seventy patients between 8-70 years of age with ASA physical status I-III were enrolled in the research and were scheduled for dynamic hip screw surgery under subarachnoid block (SAB) hip. Patients were randomly assigned in one of two groups using the hidden closed envelope method: group of FICBs (n=35): this group receives a suprainguinal iliac fascia block, the end of the injection is deep to the fascia iliaca and the lateral portion of the iliacus muscle above the iliacus. 30 mL of 0.25 percent of Bupivacaine is injected gradually beneath the fascial plane and each 5 ml is absorbed after negative aspiration. QLB Group (n=35): the group got ultrasonically-guided lumborum block transmuscular quadratus; (QLB anterior or QLB III) a needle tip between the main muscle of the psoas and the lumborum muscles of the quadratus is inserted. After negative aspiration, 30 mL of 0.25% bupivacaine is gradually administered into the fascial plane, each 5 ml aspiration. Both FIB and transmuscular QLB performed in the first 24 hour postopérative and comparable analgesic duration following hip arthroplasty operations with similar static and dynamic VAS. Both single shot blocks FIB and QLBT offer excellent postoperative analgesia afterTHA. FIB demonstrated a little reduced intake of morphine over 24 hours.
