Pericapsular Nerve Group (PENG) Block Is a Novel Technique in the Hip Surgery

Abstract

Background: Peritrochantric fracture is common especially in elderly patients. Very often we are faced with elderly and fragile patients with several comorbidities. In these cases a careful anesthetic technique is crucial to reduce comorbidity and mortality. Currently the pericapsular nerve group (PENG) block are introduced as an analgesic technique. We used PENG block for purpose of hip surgical Anesthesia. Methods: In this single-centre, case series, patients undergoing gama nailing for peritrochanteric fractures. The PENG block was performed with the patient in the supine position using ultrasound guidance. Pain scores were measured by numeric rating score (NRS) at rest and with a straight leg raise of the affected limb to 15 degrees before and 30 minutes after block performance. Results: Totally, 10 patients of ASA Grades II, III and were included who came with peritrochantric hip fracture and were scheduled for gamma nailing. The mean age of the study participants was 77 years. Significantly, pain scores reduced as compared with baseline. No such adverse events were recorded for any of the patients. Conclusion: In this article the PENG block has been determined to be safe and effective as an anesthetic technique in gamma nailing of peritrochantric fractures but more research in larger-sized studies are needed to better assess the PENG block.
