Laparoscopic Bariatric Surgery and Erector Spinae Plane Block

Antalya Training and Research Hospital54 enrolled

Overview

The aim of the study is to evaluate the effect of erector spinae plane (ESP) block on postoperative analgesic consumption in patients undergoing laparoscopic bariatric surgery

Laparoscopic sleeve gastrectomy is one of the most common surgical procedure that is chosen for bariatric surgery. Postoperative pain after bariatric surgery can de significant. Narcotic analgesics are often used to manage the postoperative pain in patients undergoing bariatric surgery. However, these drugs causes many undesirable adverse effects such as nausea, constipation, and respiratory depression. The ultrasound (USG) guided ESP block was first defined in 2016. With the administration of local anesthesia between the transverse process of the vertebra and the erector spinae muscle, it is stated that the effect mechanism of ESP is that spread blocks the ventral and dorsal rami to the paravertebral area. In the literature, it has been shown that bilateral USG guided ESP block provides effective analgesia after bariatric surgery. The aim of the study is to evaluate the effect of ESP block on postoperative analgesic consumption in patients undergoing laparoscopic bariatric surgery

Interventions

ESP block groupPROCEDURE

USG probe will be placed in a longitudinal parasagittal orientation 3 cm lateral to T7 spinous process. The erector spinae muscles will be identified hyperechoic transverse process. The patient's skin will be anesthetized with 2% lidocaine. A 21-gauge 10-cm needle was inserted using an in-plane superior-to-inferior approach or an out-plane approach. Following confirmation of the correct position of the needle with 5 ml normal saline, a dose of 20 ml %0.25 bupivacaine will be administered. The same procedure will be performed at the other site (totally 40 ml %0.25 bupivacaine). Standard pain follow up and monitorization will be performed.

Control groupPROCEDURE

The patients in this group will be performed no block. Standard pain follow up and monitorization will be performed.
