Erector Spinae vs Fascia Iliaca Block in Hip Arthroplasty

Study Overview
=================
Brief Summary
-----------------
The thoracic erector spinae plane (ESP) block was first described by Forero et al in September 2016. In their article, the authors presented the possibility of using this block as an option for the control of thoracic neuropathic pain as well as post-operative thoracic pain. The ESP block is done by administering local anesthetic in the plane deep to the erector spinae muscle, which spreads through the costotransverse foramen to the dorsal and ventral roots of the spinal nerves. Since then, there have been reports about the successful use of this block for bariatric surgery, ventral hernia repair, radical mastectomy, rib fractures, major abdominal surgery and hip replacement. However, there are no studies in the literature comparing the efficacy of the ESP block to other nerve blocks. The purpose of this study is to compare the post-operative analgesic efficacy of the ESP block to the fascia iliaca (FI) block after total hip replacement (THR).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control-group<br>No peripheral nerve block | |
| Experimental: Single-shot erector spinae plane block<br>The patient is positioned in lateral decubitus. The anesthesiologist uses a linear high-frequency probe in a longitudinal direction laterally to the mid-sagittal plane at the level of L4 until the transverse process is identified and, more superficial, the erector spinae muscle. A 22G needle of 80mm is introduced in-plane craniocaudally towards the transverse process of L4 until its tip is in the plane deep to the erector spinae muscle. Single-shot block with 30ml of ropivacaine 0,5% + adrenaline 100mcg | Procedure: Single-shot erector spinae plane block<br>* Single-shot Erector Spinae Plane block with 30ml of ropivacaine 0,5% + adrenaline 150mcg.<br>|
| Active Comparator: Single-shot fascia iliaca block<br>The patient is positioned in dorsal decubitus. The anesthesiologist uses a linear high-frequency probe in a transversal direction, below the crural arch so as to identify the femoral artery. Afterwards the probe is moved laterally to find the iliac muscle and its fascia. A 22G needle of 80mm is introduced in-plane latero-medially until its tip is below the fascia iliaca (between the muscle and its fascia). Single-shot block with 40ml of ropivacaine 0,2%. | Procedure: Single-shot fascia iliaca block<br>* Single-shot Fascia Iliaca block with 40ml of ropivacaine 0,2%<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Post-operative pain level measured by the Visual Analog Scale | Measurement of patient's pain level using the Visual Analog Scale (with a score of 0-100, 0 being no pain and 100 maximum pain) | At 6 hours post-operative | 
| Post-operative pain level measured by the Visual Analog Scale | Measurement of patient's pain level using the Visual Analog Scale (with a score of 0-100, 0 being no pain and 100 maximum pain) | At 12 hours post-operative | 
| Post-operative pain level measured by the Visual Analog Scale | Measurement of patient's pain level using the Visual Analog Scale (with a score of 0-100, 0 being no pain and 100 maximum pain) | At 24 hours post-operative | 
| Post-operative pain level measured by morphine consumption using patient-controlled intravenous analgesia | Total amount (in mg) of morphine administered by a patient-controlled intravenous analgesia pump of morphine 1mg/ml with bolus of 1ml per patient request with a lockout time of 10 minutes | At 24 hours post-operative | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Muscle Strength grade | Muscle strength grade and comparison with the contralateral limb in the quadriceps femoris muscle Muscle strength scale: Grade 0: No muscle contraction is detected Grade 1: Muscle contraction is identified but it is insufficient to produce motion Grade 2: The muscle can move the joint only if the force of gravity is eliminated Grade 3: The muscle can move the joint against gravity but without any resistance Grade 4: The muscle can move the joint against moderate resistance Grade 5: The muscle can move the joint against full resistance | At 12 hours post-operative | 
| Muscle Strength grade | Muscle strength grade and comparison with the contralateral limb in the quadriceps femoris muscle Muscle strength scale: Grade 0: No muscle contraction is detected Grade 1: Muscle contraction is identified but it is insufficient to produce motion Grade 2: The muscle can move the joint only if the force of gravity is eliminated Grade 3: The muscle can move the joint against gravity but without any resistance Grade 4: The muscle can move the joint against moderate resistance Grade 5: The muscle can move the joint against full resistance | At 24 hours post-operative |
