B超定位下臂丛神经阻滞麻醉的价值分析

Value analysis of brachial plexus block anesthesia with B-ultrasound

目的分析B超定位下臂丛神经阻滞麻醉的价值。方法选择2017年1月至2018年12月在本院接受上肢手术治疗疾病的患者280例为研究对象。依照手术日期随机分为对照组、观察组,每组140例。对照组接受传统盲探神经阻滞,观察组接受B超定位下臂丛神经阻滞,分析比较两组效果。结果相较于对照组,观察组受试者的麻醉起效时间更短,镇痛效果持续时间以及痛觉阻滞时间明显更长(P<0.05)。对照组受试者不良反应发生率为27.14%,观察组不良反应总发生率为5.71%,与对照组相比,观察组受试者不良反应发生率明显更低(P<0.05)。结论对于需要接受上肢手术患者,开展B超引导下臂丛神经麻醉阻滞能够取得满意效果,且不会增加患者术后不良反应发生率,值得进一步在临床中推广应用。

Objective To analyze the value of B-ultrasonography for brachial plexus block anesthesia.Methods A total of 280 patients who underwent upper extremity surgery in our hospital from June 2017 to December 2018 were enrolled.According to the date of surgery,they were randomly divided into control group and observation group,with 140 cases in each group.The control group received the traditional blind nerve block,and the observation group received B-ultrasound to locate the brachial plexus block.Analyzed and compared effect between two groups.Results Compared with the control group,the observation group had shorter head extension time,longer duration of analgesic effect and significantly longer pain block time(P<0.05).The incidence of adverse reactions was 27.14%in the control group and 5.71%in the observation group.Compared with the control group,the incidence of adverse reactions in the observation group was significantly lower(P<0.05).Conclusion For patients who need upper limb surgery,brachial plexus anesthesia block can achieve satisfactory results under the guidance of B-ultrasound.It does not increase the probability of postoperative adverse events in patients.It deserves further promotion and application in the clinic.
