Key Points

This research aims to evaluate the effectiveness of the PENG block in facilitating spinal anaesthesia in hip fracture patients.
Conducted a prospective, randomized trial with 60 hip surgery patients
Divided participants into PENG block and control groups
Assessed operator satisfaction, pain levels, hemodynamic alterations, and procedural metrics
Recorded parameters included sitting angle, time to CSF flow, and number of tries
PENG group exhibited significantly lower VAS scores during positioning compared to control group (p < 0.05)
27 patients in PENG group achieved optimal sitting position versus none in control (p < 0.05)
PENG group demonstrated improved hemodynamic stability and higher operator satisfaction (p < 0.05)
Fewer attempts and shorter time to CSF flow were noted in the PENG group

Abstract

Introduction: Severe pain sometimes makes it difficult to position the patients with hip fractures for spinal anaesthesia, which might impede cooperation and lengthen the process. Recently, the pericapsular nerve group (PENG) block has gained recognition as a potentially effective regional analgesic method. The purpose of this study was to assess how well it facilitates spinal anaesthesia placement. Methods: Sixty patients (ASA physical status I-III, ages 18-60) scheduled for elective hip surgery under spinal anaesthesia were included in this prospective, randomised trial. The patients were split into two groups of thirty each at random. Thirty minutes before placement, patients in the PENG group received a PENG block, whereas those in the Control group did not. Parameters recorded were operator satisfaction, hemodynamic alterations, positioning pain levels, sitting angle, time to cerebrospinal fluid (CSF) flow, number of tries, and problems associated with blocks. Results: The demographic traits of the groups were similar. The PENG group associated with much lower VAS scores than the control group (p 0.05), during positioning. While the control group experienced higher pain grades more frequently (p 0.05), the PENG group saw much lower pain scores during positioning, with the majority of patients reporting little to no discomfort. 27 patients in the PENG group and none in the control group (p 0.05) were able to achieve optimal sitting position. The PENG group also showed improved hemodynamic stability, fewer tries, shorter time to CSF flow, and higher operator satisfaction (p 0.05). There were no issues noted. Conclusion: For patients with hip fractures, the PENG block provides safe and efficient analgesia for spinal anaesthesia placement. Stable hemodynamics were maintained. Operator satisfaction was increased. Procedure time and attempts were reduced, and patient placement was improved.
