Clinical Trial Summary

There are different case studies about the use of erector spinae block (ESPB ) in nephrectomy, but there are no enough randomized controlled studies about it until now so it will be one of the earliest studies that investigate the effect of ESPB to relief acute postoperative pain in patients undergoing open nephrectomy. Although ESPB and thoracic epidural analgesia blocks successfully reduced postoperative opioid consumption in previous studies, no study has ever compared their efficacy in postoperative analgesia of adult patients undergoing open nephrectomy under general anesthesia thus in this randomized comparative study we are aiming to fill this gap in the literature. The aim of this study is to compare the analgesic effect of ultrasound-guided continuous erector spinae plane block versus thoracic epidural analgesia in open nephrectomy for renal cancer patients.

Clinical Trial Description

The erector spinae muscle (ESM) is a complex formed by the spinalis, longissimus thoracis, and iliocostalis muscles that run vertically in the back. The ESP block is performed by depositing the local anesthetic (LA) in the fascial plane, deeper than the ESM at the tip of the transverse process of the vertebra. Hence, LA is distributed in the cranio-caudal fascial plane. Additionally, it diffuses anteriorly to the paravertebral and epidural spaces, and laterally to the intercostal space at several levels. Cadaveric studies was done on ESPB using MRI to evaluate the spread of local anesthetic mixed with gadolinium dye. Showed the spread of injected volume of 30 ml at level of T10 spread between the level of T5 and T12 . Other cadaveric study showed the spread of the dye to thoracic paravertebral space which may explain the visceral analgesic effect of the block.
