超声引导下肌间沟入路臂丛神经阻滞麻醉的临床效果分析

Clinical Effect Analysis of Brachial Plexus Block Anesthesia via Intermuscular Sulcus Approach Guided by Ultrasound

目的:探讨超声引导下肌间沟入路臂丛神经阻滞麻醉的临床效果。方法:选取2021年2月—2022年2月于江苏省东台市人民医院收治的60例行肌间沟入路臂丛神经阻滞麻醉的患者作为研究对象,按照电脑盲选方式分为对照组与观察组,各30例。对照组行传统方式阻滞,观察组行超声引导下方式阻滞。比较两组麻醉效果、阻滞起效与持续时间、阻滞前后心率及平均血压、术后疼痛情况。结果:观察组麻醉总有效率高于对照组,差异有统计学意义(P=0.023)。观察组阻滞起效时间短于对照组,阻滞持续时间长于对照组,差异有统计学意义(P<0.05)。阻滞前,两组心率、平均血压比较,差异无统计学意义(P>0.05);阻滞后,两组心率高于阻滞前,平均血压低于阻滞前,差异有统计学意义(P<0.05)。观察组术后疼痛评分低于对照组,差异有统计学意义(P=0.001)。结论:超声引导下肌间沟入路臂丛神经阻滞麻醉的临床效果显著,可缩短麻醉起效时间,延长麻醉持续时间,缓解患者疼痛症状,建议应用并予以推广。

Objective:To investigate the clinical effect of brachial plexus block anesthesia via intermuscular sulcus approach guided by ultrasound.Methods:A total of 60 patients undergoing brachial plexus block anesthesia via intermuscular sulcus approach in the Dongtai People's Hospital from February 2021 to February 2022 were selected as study subjects.They were divided into control group and observation group according to the computer blind selection method,with 30 cases in each group.The control group underwent the block with traditional method.The observation group underwent the block under ultrasound guidance.The anesthesia effect,onset time and duration of block,heart rate and mean blood pressure before and after block,and postoperative pain were compared between the two groups.Results:The total anesthesia effective rate in the observation group was higher than that in the control group,with statistically significant difference(P=0.023).The onset time of block in the observation group was shorter than that in the control group,and the duration of block in the observation group was longer than that in the control group,with statistically significant difference(P<0.05).There was no significant difference in the heart rate and mean blood pressure between the two groups before block(P>0.05).In two groups,the heart rate after block was higher than that before block,and the mean blood pressure after block was lower than that before block,with statistically significant difference(P<0.05).The postoperative pain score in the observation group was lower than that in the control group,and the difference was statistically significant(P=0.001).Conclusion:The clinical effect of brachial plexus block anesthesia via intermuscular sulcus approach guided by ultrasound is remarkable,which can shorten the onset time of anesthesia,prolong the duration of anesthesia and relieve the pain symptoms of patients.It is recommended to be applied and popularized.
