Lumbal Erector Spinae Plane Block for Pain Management After Total Hip Arthroplasty

Официальное название

Ultrasound-Guided Lumbal Erector Spinae Plane Block on Postoperative Pain Management After Total Hip Arthroplasty

Обзор

The Erector Spinae Plane (ESP) block or spinal erector block was first described in September 2016 by a Canadian team. It's a block that was initially used for the treatment of chronic thoracic neuropathic pain. The ESP block is one of the inter-fascicular blocks and it's an easy-to-perform technique.In the literature, it has been reported that Lumbar ESPB provides effective analgesia after a hip surgery. The purpose of this prospective randomized study was to compare the analgesic effects of the ultrasound-guided lumbar Erector Spinae Plane block on postoperative pain management versus the multimodal analgesia after total hip arthroplasty.

Подробное описание

Patients aged more than 18 years, ASA I-III scheduled for primary total hip arthroplasty with lateral approach and under general anesthesia Patients were randomly assigned, into 1 of 2 groups, namely, group ESPBL and group Placebo, using sealed envelopes

* For ESPBL group: Lumbar ESP block performed after anesthesia induction. A low-frequency ultrasound probe will be placed longitudinally 2-3 cm lateral to the L4 transverse process. Erector spinae muscle will be visualized on the hyperechoic transverse process. The block needle (100 mm, 22G) will be inserted cranio-caudal direction and following confirmation of the correct position of the needle, between the erectorspinae muscle and the transverse process,30 ml of local anesthetic (0.25% bupivacaine/0.2% ropivacaine) will be administered for the block. * For Placebo group: patients had multimodal analgesia without lumbar ESP block Patients will be transferred to continuous care unit for 24 hours.

Post-operative analgesia will include:

1. Paracetamol 1g IV every 8 hours for 1 day then oral paracetamol 1g every 8 hours for 4 weeks. 2. Diclofenac sodium(50mg) 1 tablet x 2 per day for 5 days. 3. PCA morphine (Patient Controlled Analgesia), as a rescue analgesia, programmed as: Bolus of 1mg/ refractory period of 10 min/ maximum dose set up at 10mg every 12h.

The primary outcome of the study is to compare postoperative opioids consumption in the first 24 postoperative hours.

Secondary endpoints:

Secondary outcomes are: intraoperative opioid consumption, postoperative pain scores, sitting position and adverse effects related to opioids.
