目的探讨超声引导下臂丛神经阻滞麻醉在儿童上肢手术中的疗效。方法选取2015年10月至2016年10月来我院进行上肢手术治疗的患儿48例,并按照随机原则,将其分为实验组与对照组。对照组患儿行传统解剖定位臂丛神经阻滞麻醉,实验组患儿行超声引导下臂丛神经阻滞麻醉。对两组患儿的麻醉用药量、起效时间以及阻滞效果进行比较分析。结果经过比较发现,实验组患儿的麻醉用药量显著小于对照组,起效时间快,麻醉阻滞时间显著长于对照组,P<0.05,具有统计学意义。结论超声引导下儿童臂丛神经阻滞麻醉效果显著高于传统解剖定位阻滞法,且用药量少,起效时间快,对患儿造成的损伤较小,安全性高,值得在临床上推广应用。
Objective To investigate the efficacy of ultrasound-guided brachial plexus block anesthesia in children’s upper extremity surgery. Methods Forty-eight children with upper limb surgery in our hospital from October 2015 to October 2016 were selected and randomly divided into experimental group and control group. Children in the control group underwent traditional anatomic brachial plexus block anesthesia. The experimental group underwent ultrasound-guided brachial plexus block anesthesia. The anesthetic dosage, the onset time and the blocking effect of two groups of children were comparatively analyzed. Results After the comparison, we found that the dosage of anesthesia in the experimental group was significantly smaller than that of the control group, the onset time was fast, the anesthesia block time was significantly longer than that of the control group, P <0.05, with statistical significance. Conclusion Ultrasound-guided anesthesia of brachial plexus block in children is significantly higher than that of traditional anatomical blockade method, and the dosage is low, the onset time is quick, the damage to the children is small and the safety is high, which is worth to be popularized clinically application.
