Perioperative Analgesia for Total Hip Arthroplasty

Study Overview
=================
Brief Summary
-----------------
This study is comparing the effect of lumbar plexus block and fascia iliaca block with general anesthesia to provide perioperative pain control and compare their effects on hemodynamics

Detailed Description
-----------------
Different groups receive different interventions at same time during study. patients were randomly allocated in two groups : Group A: lumbar plexus block using shamrock technique by 0.3 ml/kg of 0.5% bupivacaine with 1:200000 adrenaline. Group B: Fascia iliaca block by 0.3 ml/kg of 0.5% bupivacaine with 1:200000 adrenaline.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessment of postoperative analgesia | each patient was assessed by visual analogue scale which consists of a 10 cm line with one end labelled no pain and the other end labelled worst pain imaginable. The patient marks the line at the point that best describes the pain intensity | 24 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compare effects of both groups on mean arterial blood pressure | monitoring of blood pressure using non invasive blood pressure measurement in millimeter mercury | intraoperative and 24 hours |
