The study was designed as a double-blind, prospective randomized controlled trial.~Blindness; The healthcare professionals who will monitor the patient's pain in the post-operative period will not know which of the ESP or RLB block is applied. Randomization of the patients was planned using computer aided. It was envisaged to include 40 participants each in the ESP block and RLB block groups. The current pain status of the patients in the ESP block and RLB block groups in the postoperative period was determined by NRS (Numerical rating scale) at rest and motion at certain hour intervals (30 .min,1.,6.,12.,24. hours) will be done, when the patients' NRS scores are 4 and above, an additional intravenous analgesic will be administered and the number of bolus doses with PCA in the first 24 hours will be recorded. The recovery quality of the patients who underwent both ESP block and RLB block at the postoperative 24th hour will be evaluated with a (QoR-40) scoring system. In addition, the hemodynamic values of the patients will be recorded in these intervals.
The aim of this study is to compare the efficacy of erector spinae plane block (ESPB) and Retrolaminar Block on postoperative recovary quality and pain after lumbar spinal surgery
