The Effects of ESP Block and Mid-Transverse Process to Pleura Block on Postoperative Opioid Consumption and Quality of Recovery

Comparison of the Effects of Erector Spinae Area (ESP) Block and Mid-Transverse Process to Pleura Block(MTP) on Postoperative Opioid Consumption and Quality of Recovery in Lumbar Spinal Surgery

Erector Spinae Area (ESP) Block and Mid-Transverse Process to Pleura Block(MTP) have recently been described for the treatment of pain after lumbar spinal surgery. Although these blocks have been shown to be effective in the treatment of pain after lumbar spinal surgery when compared with postoperative pain, they have not been compared in terms of the quality of recovery and opioid consumption after lumbar spinal surgery.

The aim of this clinical trial is to compare the effects of Erector Spinae Area (ESP) Block and Mid-Transverse Process to Pleura Block(MTP) on quality of recovery and opioid consumption in patients scheduled for lumbar spinal surgery. The effects of the 2 blocks on postoperative pain will also be compared and recorded.
