Description

Total hip arthroplasty (THA) has been one of the most significant advancements in orthopedic surgery over the past century. hip fractures are typically associated with severe pain, effective analgesia is crucial both before and after surgery.Spinal anesthesia (SA) is the most commonly employed method of anesthesia for repairing these fractures.The anterior iliopsoas space block is a considered as a novel technique that targets the lumbosacral trunk as it passes beneath the psoas major muscle, offering potential advantages over the traditional sacral plexus block, which is performed in the supine position.

Interventions

Bupivacaine (Drug)
The site to be blocked will be painted with 5% povidone iodine followed by 70% ethyl alcohol and draped. Linear high-frequency ultrasound probe (7 -15 mhz) (General Electric; GE, "LOGIQ E") will be initially placed in a transverse plane over the anterior superior iliac spine (ASIS) and then alignes to identify the following landmarks: Anterior inferior iliac spine, ilio-pubic eminence, iliopsoas muscle and tendon, the femoral artery, and Pectineus muscle. Point of injection will be musculo-fascial plane between the psoas tendon and ilio-pubic eminence.
Bupivacaine (Drug)
placing a patient supine, identifying the anterior superior iliac spine and iliac crest, the skin of the block region will be cleaned with 5% povidone iodine followed by 70% ethyl alcohol .Both the sterile window sheets and probe will be covered with sterile drapes. A standardised amount of local anaesthetic will be administered utilising ultrasound guidance and a portable ultrasound system (General Electric; GE, "LOGIQ P5")to visualize the iliopsoas muscle in a transverse or longitudinal scan. The needle is advanced in-plane to the fascial plane between the iliopsoas muscle and the iliofemoral ligament or iliac bone, and local anesthetic is injected to spread along the iliopsoas muscle.

Eligibility criteria

Inclusion Criteria: * (ASA )classes I and II * patients of either sex, above the age of 18 who will undergo hip surgeries( (Dynamic hip screw fixation or hemiarthroplasty)(not older than 2 weeks) with persistent pain and scheduled for surgery under SA with an expected duration of 2.5 hours Exclusion Criteria: * patient's refusal to participate * any contraindications to SA or peripheral nerve blocks * history of ischemic heart disease * patients on opioids for chronic pain * patients with significant cognitive impairment.
