By selecting the simple randomization method in the randomization box and entering the determined total sample size in this software, numbers were given to the patients and the patients were allocated into two groups according to computer-generated numbers, Blinding description: The patient and the outcome assessor were blinded to the patients' spinal anesthesia approach (anesthetized by median or paramedic approach). An anesthesiologist performed spinal anesthesia in the operating room for randomly selected patients. The patient was only aware that a spinal block was being performed on him, but he was blinded to the needle approach in the median and paramedical method, and the outcome assessor in the later stages was blinded to the type of anesthesia approach (median or paramedian). He only realized that a spinal block had been performed on the patient, but he was blinded to the type of needle approach technique. 3 Post-Dural Puncture Headache. Intervention 1: Intervention group: group 1: Spinal anesthesia was conducted in the lumbar intervertebral space 4 and 5 with a 25g Quincke needle and 12 mg Marcaine 0.5 % (Marcain® made by Cobel company) by using the median method. Intervention 2: Intervention group: group 2: Spinal anesthesia was conducted in lumbar intervertebral space 4 and 5 with a 25g Quincke needle and 12 mg Marcaine 0.5 % (Marcain® made by Cobel company) by using the paramedian method.
