Brief Summary

The investigators research was designed as a single-center, prospective, randomized double-blind study. The patients undergoing total hip replacement surgery in Istanbul University Istanbul Medicine Faculty Department of Orthopedics and Traumatology will be included. Patients or persons who are legally authorized to make decisions on their behalf will be informed about the research and their written consent will be obtained. Patients who do not give consent will not be included in the study. Patients will be given US guided PENG blocks using a 22 gauge 10 mm block needle after compliance with the rules of asepsia and antisepsis in the supine position according to the group of patients in which they were included. PENG block will be done for postoperative analgesia. After the PENG block, a single dose of spinal anesthesia will be applied as a regional anesthesia method, in a sitting position, using the appropriate spinal needle, as is routinely applied in the investigators clinic. After the block is completed, the pinprick test will be done and the operation will be started after the successful completion of the block is confirmed. Oxygen will be given to the patients with a face mask at 4 lt / min throughout the operation. ECG, saturation, invasive / noninvasive blood pressure monitoring of the patients will be done. Measurements made at 5-minute intervals will be recorded. In the investigators clinic, the use of PENG block and PCA (patient controlled analgesia) device with intravenous morphine for postoperative analgesia is routinely performed. In this study, four randomized groups will be formed together with the control group. The local anesthetic solution given by the supervisor, whose doses of local anesthetic are predetermined (the investigators and participants do not know the dosage), with a total volume of 20 cc will be used. Local anesthetic agent will not be applied to the control group. As mentioned above, spinal anesthesia will be performed after PENG block and the operation will be started. Pain score and total morphine consumption will be determined by visual pain scoring (VAS) at the postoperative 0, 6, 12, 24 and 48th hours by providing the use of a PCA device with intravenous morphine applied in routine practice to all four groups. As in routine practice, when VAS\>4 after each interrogation, morphine 0.05 mg/kg iv will be administered as additional analgesia and the maximum will be increased to 10 mg. Pain management will continue when VAS \<4.
