B型超声引导下臂丛神经阻滞在上肢手术中的麻醉效果

Anesthesia Effect of B-mode Ultrasound-Guided Lower Brachial Plexus Block in Upper Limb Surgery

目的分析上肢手术中应用B型超声引导下臂丛神经阻滞后的麻醉效果。方法选取昆明市呈贡区人民医院2018年3月至2020年1月收治的90例上肢手术患者进行麻醉效果研究,根据电脑随机法分为研究组与对照组,每组45例,分别行B型超声定位麻醉方案与传统穿刺定位方案,观察两组患者麻醉效果、麻醉安全性、麻醉阻滞情况。结果对照组麻醉操作完成时间低于研究组,差异有统计学意义(P<0.05);对照组运动阻滞起效时间、感觉阻滞起效时间小于研究组,差异有统计学意义(P<0.05);对照组患者麻醉后不良反应发生率为6例(13.33%),研究组无不良反应发生,组间比较差异有统计学意义(P<0.05);对照组尺神经完全阻滞11例(73.33%),研究组尺神经完全阻滞15例(100.00%),差异有统计学意义(P<0.05)。结论综上所述,B型超声定位方案在上肢手术中虽然定位时间较长,但安全性更高,臂丛神经阻滞情况较好。

Objective To analyze the anesthetic effect of B-ultrasound-guided brachial plexus block in upper limb surgery.Methods A total of 90 patients with upper limb surgery in Kunming Chenggong District People's Hospital from March 2018 to January 2020 were selected and randomly divided into study group and control group,45 cases in each group.Anesthesia effect,anesthesia safety and anesthesia block were observed in two groups by B ultrasound and traditional puncture.Results The completion time of anesthesia operation in the control group was lower than that in the study group,the difference was statistically significant(P<0.05);the onset time of motor block and sensory block in the control group was lower than that in the study group,the difference was statistically significant(P<0.05);The incidence of adverse reactions after anesthesia in the control group was 6 cases(13.33%),There was no adverse reaction in the study group,and the difference between the two groups was statistically significan(P<0.05);There were 11 cases(73.33%)of ulnar nerve block in control group and 15 cases(100.00%)in study group,the difference was statistically significant(P<0.05).Conclusion To sum up,although the positioning time of B-mode ultrasound positioning scheme in upper limb surgery is longer,it has higher safety,better brachial plexus block,better application effect.
