Comparison of the Effects of Local Anesthetic Infiltration and Erector Spinae Plan (ESP) Block on Postoperative Recovery Quality and Pain in Lumbar Spinal Surgery

The study was designed as a double-blind, prospective randomized controlled study. Blindness; healthcare professionals who will monitor the patient's pain in the postoperative period will not know whether ESP or wound local anesthetic infiltration block was applied. Randomization of the patients was planned to be done using computer support. It was planned to include 44 participants in the ESP block and wound local anesthetic infiltration groups. The current pain status of the patients in the ESP block and wound local anesthetic infiltration groups in the postoperative period will be evaluated with NRS (Numerical rating scale) at certain time intervals (30th min, 1st, 6th, 12th, 24th hour) during rest and movement. When the patients' NRS scores are 4 and above, intravenous analgesic will be administered additionally and the number of bolus doses of the patients 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 the scoring system (QoR-40). Additionally, the patients' hemodynamic values will be recorded during these intervals.
