临床医学专业 超声联合神经刺激仪定位下行肌间沟臂丛神经阻滞的安全性与有效性分析

超声联合神经刺激仪定位下行肌间沟臂丛神经阻滞的安全性与有效性分析摘要：目的：探讨超声联合神经刺激仪定位下行肌间沟臂丛神经阻滞的安全性以及有效性。 方法：选取2015 年 1 月至 2016 年 1 月来我院进行上肢手术治疗的患者 96 例，并按照随机平均的原则，将其分为实验组与对照组。实验组 48 例患者行超声联合神经刺激仪定位，对照组 48 例患者行超声引导定位。两组患者均行肌间沟臂丛神经阻滞，使用药物为 0.5%罗派卡因25ml，对患者的穿刺操作时间进行记录，并对各患者主要神经的感觉阻滞情况、麻醉效果进行记录分析。 结果：经过比较发现，实验组与对照组患者在痛觉阻滞效应比较上无明显差异，P＞0.05，不具有统计学意义。且实验组患者麻醉效果优良率显著高于对照组患者，P＜0.05，具有统计学意义。 结论：超声联合神经刺激仪定位下行肌间沟臂丛神经阻滞，具有定位准确、麻醉时间较短以及定位成功率高等优点，临床价值较高，值得在临床上推广应用。关键词：超声、神经刺激仪、下行肌间沟臂、丛神经阻滞、安全性、有效性Safety and effectiveness of ultrasound-guided neurostimulation in locating inferior interscalene brachial plexus blockAbstract: Objective: To investigate the safety and effectiveness of ultrasound combined with neurostimulation instrument to locate interscalene brachial plexus block. Methods: From January 2015 to January 2016, 96 patients with upper extremity surgery were randomly divided into experimental group and control group according to the principle of random average. 48 patients in the experimental group were treated with ultrasound combined with neurostimulation instrument and 48 patients in the control group were guided by ultrasound. Two groups of patients were interscalene brachial plexus block, the drug was 0.5% ropivacaine 25ml, the time of the puncture operation were recorded, and the main nerve of patients with sensory block, anesthesia effect analysis. Results: Compared with the control group, there was no significant difference in pain block effect betw...
