Effect of ultrasound-guided peripheral nerve block on postoperative functional recovery in elderly patients undergoing lower extremity orthopedic surgery
超声引导下外周神经阻滞对老年下肢骨科手术患者术后功能恢复的影响

摘要

目的 分析老年下肢骨科手术用超声引导下外周神经阻滞的价值。方法 对2019年2月-2022年2月本科接诊老年下肢骨科手术病人（n=100）进行随机分组，试验和对照组各50人，前者采取超声引导下外周神经阻滞，后者行坐骨神经阻滞麻醉。对比术后下床时间等指标。结果 关于痛觉阻滞时间、下床时间、术后清醒时间和麻醉起效时间，试验组比对照组短（P＜0.05）。关于药物用量，试验组的数据是（62.53±7.91）mg，和对照组（76.16±8.52）mg相比更少（P＜0.05）。关于FMA评分，术后：试验组的数据是（26.68±3.95）分，和对照组（20.47±3.53）分相比更高（P＜0.05）。结论 老年下肢骨科手术用超声引导下外周神经阻滞法，术后功能恢复更为迅速，痛觉阻滞时间也更短，药物用量更少，麻醉效果更好。

Abstract

Objective To analyze the value of ultrasound-guided peripheral nerve block in elderly lower extremity orthopedic surgery.
Methods: From February 2019 to February 2022, elderly patients (n=100) receiving lower extremity orthopedic surgery were randomly divided into two groups: 50 patients in the former group received ultrasound-guided peripheral nerve block and 50 patients in the control group received sciatic nerve block anesthesia. The time to get out of bed after operation was compared.
Results: The experimental group was shorter than the control group in terms of pain block time, time to get out of bed, time to wake up after operation and time to start anesthesia (P < 0.05). As for drug dosage, the data of experimental group was (62.53±7.91) mg, which was lower than that of control group (76.16±8.52) mg (P < 0.05). As for FMA score, the postoperative data of the experimental group was (26.68±3.95), which was higher than that of the control group (20.47±3.53) (P < 0.05).
Conclusion  : Ultrasound-guided peripheral nerve block in elderly lower extremity orthopedic surgery has a faster postoperative function recovery, shorter pain block time, less drug dosage and better anesthesia effect.
