The Efficiency of Preoperative Pericapsular Nerve Group Block Applied With Ultrasound and Success of Spinal Anesthesia

We aimed to investigate the effectiveness of the pericapsular nerve group (PENG) block applied with preoperative ultrasonography (USG) in patients who were operated on under spinal anesthesia due to hip fracture and whether it influences spinal anesthesia success. The files of 100 patients were reviewed observationally, and 60 patients were included in the study. The patients were divided into two groups: Group P (n = 30) comprising patients who underwent PENG block under USG guidance before the start of surgery and the control group (Group C; n = 30) of patients in whom tramadol infusion was started. From the files of the patients, the transition from the bed to the operating table, lateral decubitus position, skin incision, postoperative exit, postoperative 2nd, 4th, 12th, and 24th hour numeric rating scale (NRS) values, spinal anesthesia duration and number of attempts, and perioperative total tramadol consumption were recorded. During the transfer from the patient bed to the operating table and during the lateral decubitus position, postoperative exit and postoperative 2nd, 4th, 8th, 12th, and 24th hour NRS values were found to be significantly lower in Group P. In addition, lower spinal anesthesia time, lower number of spinal anesthesia attempts, and lower perioperative total tramadol consumption were detected in Group P. We found that PENG block applied preoperatively to patients with spinal anesthesia decreased the perioperative pain score, increased the success of spinal anesthesia by facilitating positioning for spinal anesthesia, and decreased the need for postoperative opioids.
