pre-post erector spine plane block-spinal surgery

Conditions: Opioid Use; Pain, Acute

Summary: spinal surgery patients generally have chronic pain in the preoperative period and are exposed to widespread and severe acute pain postoperatively. in spinal surgery patients, providing postoperative analgesia is important not only for the patient's comfort but also for preventing the negative effects of pain on the systems, allowing early mobilization, reducing hospital stay and especially reducing chronic pain syndrome. although esp block is routinely used in spinal analgesia, the answer to the question of whether investigators should perform the block after putting the patient to sleep or before waking the patient after completing the surgery is not clear. preference varies among anesthesiologists.you investigators propose a randomized double-blind study comparing patients who underwent esp block before surgery (group 1) with patients who underwent esp block after surgery (group 2).

investigators propose a randomized double-blind study comparing patients who underwent esp block before surgery (group 1) with patients who underwent esp block after surgery (group 2). blind patients and postoperative follow-ups will not know which group the patient is in the study. the study will be conducted at adnan menderes university hospital with the approval of the ethics committee and the written consent of the patients. the study will be registered on the clinicaltrials.gov website before the first patient is enrolled. preoperative visit documentation of eligibility and consent will be confirmed at the preoperative visit. during this visit, patients will provide demographic and historical medical information, including information regarding medication use. they will fill out the qr-40 quality compilation survey form. intraoperative the clinic's routine anesthesia protocol will be applied to the patient. anesthesia will not be interfered with. group 1: following induction of anesthesia, esp block will be performed before the surgery begins, group 2: esp block will be performed before waking the patient at the end of surgery. postoperative the peroperative analgesia plan will be applied the same to all patients. in this protocol, intravenous paracetamol was determined as 1 g and tramadol was determined as 1 mg/kg. then it is paracetamol every eight hours and tramadol from pca. at the end of the operation, patients' pain levels will be determined and recorded with the numeric rating scale (nrs) system at postoperative intervals. the quality of recovery (qor-40) of both groups of patients at the 24th postoperative hour will be evaluated with a scoring system.
