Application of hip capsule peripheral nerve block in early analgesia in elderly patients with hip fracture

Abstract

Objective: The objective of the study is to investigate the effect of pericapsular nerve group (PENG) block in early analgesia in elderly patients with hip fracture. Methods: A total of 44 elderly patients with hip fracture admitted to our hospital from August 2021 to December 2022 were selected and divided into 2 groups according to different analgesia programs. Results: At T1~T4, the resting and active visual analog scale (VAS) scores in group P were lower than group F (p < 0.05). The resting and active VAS scores at T5 in both groups were no visible differences (p > 0.05). After 30 min of block, systolic blood pressure, diastolic blood pressure, and heart rate were decreased in both groups (p < 0.05), but no obvious difference was found in the two groups (p > 0.05). Before surgery, Pittsburgh Sleep Quality Index (PSQI) and mini–mental state scale (MMSE) scores in both groups were reduced, and PSQI score in group P was lower than that in group F and MMSE score was higher than group F (p < 0.05). Conclusions: PENG technology is safe and effective in the early analgesia of elderly hip fractures. It can effectively block physiological stress response caused by acute trauma, improve pre-operative sleep quality, and reduce the incidence of cognitive dysfunction.
