Comparison of Pain Relief Methods for Hip Surgery: A Study on Two Different Nerve Block Techniques

This prospective randomized comparative study aims to compare the analgesic efficacy of pericapsular nerve group block (PENG) and lumbar erector spinae plane block (L-ESP) groups to relieve postoperative pain in participants over the age of 18 undergoing total hip arthroplasty under spinal anesthesia. The main question it aims to answer is: To demonstrate whether PENG block or L-ESP block is more effective in postoperative analgesia in patients undergoing total hip arthroplasty surgery based on pain scores, opioid consumption, and patient satisfaction. Total hip arthroplasties cause severe pain with movement in the postoperative period. After surgery, the movements of the participants are severely restricted, which increases the possibility of complications. In this study, the participants' pain status, VAS score, opioid consumption through patient-controlled analgesia, and patient satisfaction will be measured with a questionnaire for 24 hours at predetermined time points and then compared. Both types of blocks have pain-relieving effects. This study will only investigate which one is more effective in reducing pain, and there will be no deficiency in relieving the pain of the participants.
