ESP vs FIB in hip arthroplasty

Details and patient eligibility

About

The aim of this study is to compare between the analgesic efficacy of ESP block and FIB in patients undergoing hip arthroplasty.

Full 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.
