Comparison Between Ultrasound Guided Erector Spinae Plane Block and Dexmedotomidine in Lumber Spine Surgeries.

Comparison Between Ultrasound Guided Erector Spinae Plane Block and Dexmedotomidine in Lumber Spine Surgeries.

Ultrasound (US) guided Erector spinae plane block (ESPB) as a new trunchal fascial plane block technique was proposed in 2016. US guided ESPB has aroused the interest of many nerve block experts. The goal of this study is to evaluate the effect of US guided ESPB versus (VS) intravenous Dexmedotomidine on postoperative analgesia and intra operative hemodynamic parameters in lumbar spine surgeries.

The aim of this study is to compare the efficacy of ESPB to intravenous Dexmedetomidine in patients who are undergoing elective lumber spine surgeries regarding the effect on postoperative analgesia and intra operative hemodynamic parameters.

The use of US guided ESPB in lumbar spine surgery has not been extensively studied in clinical research. Although there is limited research available, some studies have highlighted differences in the mechanism and effectiveness of the block in different regions of the erector spinae muscle. Some scholars question the practicability of US guided ESPB in lumbar surgery. This suggests that further investigation is needed to understand the practicality and potential benefits of using ultrasound-guided ESPB in lumbar spine surgery.

Dexmedetomidine, a highly selective α₂ receptor agonist, has a sympatholytic, sedative, amnestic and opioid sparing effect. It does not cause respiratory depression and can therefore be used as an adjuvant in certain clinical settings .
