Detailed Description
Hip arthroplasty surgery is usually associated with severe postoperative pain. Several modalities are usually used for postoperative analgesia in these patients, those include; intravenous analgesia, neuraxial analgesia and peripheral nerve blocks.
Peripheral nerve blocks have several advantages such as; potent analgesia, lower motor impairment and minimal systemic complications.
Lumbar plexus block and supra-inguinal fascia iliaca block (FIB) are the most commonly performed peripheral nerve blocks for hip surgeries.
Fascia iliaca block is one of the most common techniques for pain control after hip surgeries; it can be regarded as an anterior approach of the lumbar plexus. It provides analgesia through spread of local anaesthetic to the femoral and lateral cutaneous femoral nerves.
Ultrasound guided erector spinae plane (ESP) block is a recent regional anesthetic technique. It was first described in 2016 for acute and chronic thoracic pain management. It is a paraspinal fascial plane block that provides analgesia through injecting local anesthetic drugs to block the ventral and dorsal rami of spinal nerves in the paravertebral area.
To the best of the investigators knowledge, the use of ESP block in hip surgery was only investigated in one study and few case reports. Therefore, further randomized controlled studies are needed to prove this hypothesis.
This study aims to investigate the efficacy of ESP block in hip replacement compared to the supra-inguinal FIB.
The investigators hypothesize that erector spinae block may provide better postoperative analgesia than fascia iliaca block, since erector spinae block provides analgesic cover for the entire lumbar plexus rather than just peripheral nerves provided by fasicia iliaca.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: ESPB Group
This group will receive ultrasound-guided erector spinae plane block and subarachnoid block.
|
Patients will be placed in the lateral position.Ultrasonography will be performed by an experienced anesthetist.The 4th lumbar vertebral level will be determined using the conventional method (imaginary line between two iliac crests).
The low frequency convex probe (2-5MHz) will then be placed at the mid-vertebral line in the sagittal plane.
It will be shifted from the midline, 3.5-4 cm lateral to the side of the surgery to visualize the erector spinae muscle and transverse process.
Using the out-plane technique a 22G/80-mm block needle will be advanced until it reaches the transverse process.
After negative aspiration, 0.5-1 ml of the prepared local anaesthetic solution (20 ml bupivacaine 0.5%, 10 ml lidocaine 2%) and 10 ml normal saline will be administered for hydrodissection to confirm correct location.
The needle will be repositioned by pulling back a few millimeters if resistance occurred when injecting local anesthesia
|
Active Comparator: FIB Group
This group will receive supra-inguinal fascia iliaca block and subarachnoid block .
|
Patients will be placed in supine position. Ultrasonography will be performed by an experienced anesthetist using ultrasound device equipped with a low frequency (2-5 MHz) convex probe and an echogenic 21 G/ 10 cm needle will be used. The probe will be placed in the inguinal crease. Scan will be started laterally from the femoral artery and nerve in the inguinal crease to identify the Sartorius muscle. The muscle will then be traced until its origin at the anterior superior iliac spine is identified and the shadow of the bony of iliac crest & iliacus muscle will be seen. Injection will be performed at the plane deep to the fascia iliaca and above the lateral part of the iliacus muscle. After negative aspiration, the prepared local anaesthetic solution (15 ml bupivacaine 0.5%, 15 ml normal saline) will be injected incrementally, aspirating every 5 ml. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total morphine requirements
Time Frame: 24 hours postoperatively
|
Amount of morphine required postoperatively
|
24 hours postoperatively
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Visual analogue pain score
Time Frame: at rest at 2, 4, 6, 12, 18, and 24 hours postoperatively
|
The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain.
Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain."
|
at rest at 2, 4, 6, 12, 18, and 24 hours postoperatively
|
Time to first postoperative analgesic request
Time Frame: 24 hours postoperatively
|
If the visual analogue scale (VAS) was 4 or more, a morphine increment (2 mg) will be added to maintain a resting VAS at <3 and the total 24-hours morphine consumption will be recorded.
|
24 hours postoperatively
|
Quadriceps muscle power strength
Time Frame: at 6, 12 and 24 hours postoperatively
|
For motor block assessment, the patient knee will be fully flexed and the patient will be asked to extend it.
The motor block will be classified as follows: grade 0; normal muscle power, grade 1; motor weakness, grade 2; complete motor paralysis
|
at 6, 12 and 24 hours postoperatively
