超声引导下神经阻滞麻醉对小腿骨折急诊外固定手术的效果研究

Study on the effect of ultrasound-guided nerve block anesthesia on emergency external fixation of lower leg fracture

目的 研究超声引导下神经阻滞麻醉对小腿骨折急诊外固定手术的效果。方法 40例行急诊外固定手术的小腿骨折患者,随机分为研究组和对照组,各20例。研究组采用超声引导下神经阻滞麻醉,对照组采用全身麻醉。比较两组患者的术前跨度时间、镇痛满意度评分及并发症发生情况。结果 研究组术前跨度时间为(4.3±1.3) h,对照组术前跨度时间为(9.4±2.2)h;研究组术前跨度时间明显短于对照组,差异有统计学意义(P<0.05)。研究组患者镇痛满意度评分(9.0±1.1)分高于对照组的(4.9±1.3)分,差异有统计学意义(P<0.05)。两组并发症发生率比较,差异无统计学意义(P>0.05)。结论 对行急诊外固定手术的小腿骨折患者应用超声引导下神经阻滞麻醉可显著缩短术前跨度时间,明显提升镇痛效果,具有良好的应用价值。

Objective To study the effect of ultrasound-guided nerve block anesthesia on emergency external fixation of lower leg fracture. Methods A total of 40 patients with lower leg fracture undergoing emergency external fixation were randomly divided into research group and control group, with 20 cases in each group. The research group received ultrasound-guided nerve block anesthesia, and the control group received general anesthesia. The preoperative time span, analgesic satisfaction score and complications were compared between the two groups. Results The preoperative time span in the research group was(4.3±1.3) h, and the preoperative time span in the control group was(9.4±2.2) h. The preoperative time span in the research group was significantly shorter than that in the control group, and the difference was statistically significant(P<0.05). The analgesic satisfaction score(9.0±1.1) points in the research group was higher than(4.9±1.3) points in the control group, and the difference was statistically significant(P<0.05). There was no statistically significant difference in complication rate between the two groups(P>0.05). Conclusion Ultrasound-guided nerve block anesthesia can significantly shorten the preoperative time span of emergency external fixation of lower leg fracture, and significantly improve the analgesic effect, which is of high application value.
