Background and objective: The objective of the present study was to determine the effectiveness of erector spinae plane block (ESPB) for pain relief in patients undergoing percutaneous nephrolithotomy. Methods: Sixty-four patients of either sex, American Society of Anaesthesiology (ASA) Grade I/II for surgery were enrolled. After informed consent, all participants received subarachnoid block with 3 ml of 0.5% injection heavy bupivacaine. Participants in the block group received ultrasound-guided ESPB with 30 ml of 0.5% ropivacaine, whereas participants in the control group received routine analgesia as per our hospital’s protocol for percutaneous nephrolithotomy procedure which is tramadol 100 mg intravenously. This prospective, single-blind, randomized, controlled study was conducted after approval from the institutional ethics committee (SRHU/HIMS/RC/2019/291) and written informed consent was obtained for surgery under spinal anesthesia. Pain score (visual analog scale, VAS) was evaluated by the anesthesiologist who was not involved in the study at 30 minutes and 2, 4, 6, 8, 12, 18, and 24 hours postoperatively and patient was monitored with electrocardiogram, noninvasive blood pressure, heart rate, and pulse oximetry. Unpaired t test was used for comparison between the groups. Results: Both the groups were appropriately matched for age, ASA physical status, weight, and duration of surgery. The total dosing of rescue analgesia, that is, tramadol was considerably more in the control group in comparison with the ESPB group in the first postoperative day (P = 0.000; 218.75 ± 82.06 mg vs. 103.12 ± 47.41 mg, respectively). Similar results were obtained in the VAS pain score. Conclusion: ESPB helped in providing considerable postoperative pain relief in patients undergoing percutaneous nephrolithotomy.
