The aim of our study is to determine the superior procedure in analgesia management by comparing the traditional wound infiltration technique with the ultrasound-guided bilateral erector spina plan block technique in spinal surgery patients.

Patients in ASA I-II-III risk group aged 18-80 who will undergo spinal surgery by Trakya University Faculty of Medicine, Brain and Nerve Surgery will be included. In this study, patient data will be collected in the form of file scanning. Intra-operative; hemodynamic data of patients; heart rate, blood pressure values, anesthetic and other drugs applied, surgery and anesthesia durations will be written from the anesthesia document after the operation is over. In the study, the application preferred by the anesthesiologist for the patient will not be intervened. The patients will be divided into three groups; wound infiltration technique was applied, ultrasound-guided bilateral erector spina plan block technique was applied and both techniques were applied together. After the operation; pain values will be calculated by VAS at the 1st, 2nd, 4th, 6th, 12th and 24th hours of the patients. The patient's length of stay, satisfaction (excellent, good, moderate, poor) and methods used for analgesia will be recorded. With the results collected in our study, it will be determined which procedure is superior in pain management for spine surgery.

Inclusion Criteria:

• Undergoing elective spine surgery
• No contraindication to the technique to be applied
• Not pregnant
• Being over the age of 18

Exclusion Criteria:

• Undergoing emergency spine surgery
• There is an obstacle to the technical process to be applied
• Pregnant patients
• Patients younger than 18 years old

Patients in ASA I-II-III risk group aged 18-80 who will undergo spinal surgery by Trakya University Faculty of Medicine, Brain and Nerve Surgery will be included. 75 patients meeting these conditions will be included in the study.
