不同剂量罗哌卡因应用于高龄高危患者骨科下肢手术麻醉的临床价值探析

Clinical Value of Different Doses of Ropivacaine in Anesthesia for Lower Limb Surgery In Department of Orthopedics For Elderly And High-Risk Patients

目的研究高龄高危患者骨科下肢手术麻醉中应用不同剂量罗哌卡因的效果。方法选择2015年1月—2016年12月该院高龄高危下肢骨折患者患者50例,全部患者根据利用罗哌卡因的剂量不同分为A组、B组,分别给予0.5%、0.65%质量分数的罗哌卡因,分析麻醉效果。结果 A组运动恢复时间较B组更短(P<0.05),2组患者感觉阻滞起效时间、最大阻滞时间、运动阻滞起效时间、最大运动阻滞时间、感觉阻滞最高平面结果差异无统计学意义(P>0.05)。结论高龄高危患者骨科下肢手术中应用0.5%质量分数的罗哌卡因实施腰硬联合麻醉能够加快患者术后恢复,能够保证麻醉安全性,可在临床推广应用。

Objective To study the application of different doses of ropivacaine anesthesia for lower limb surgery in elderly high-risk patients in Department of orthopedics effect. Methods From January 2015 to December 2016 in our hospital 50 cases of lower extremity fractures in patients with high-risk patients,all patients according to the different dose of ropivacaine were divided into A group,B group,were given 0.5% ropivacaine,0.65% mass fraction analysis,effect of anesthesia.Results In group A compared with group B shorter recovery time(P<0.05),2 groups of patients with the onset time of sensory block,the largest block of time,motor block onset time,motor block,sensory block There are no significant differences between the highest level of results(P>0.05). Conclusion Ropivacaine 0.5%mass fraction of high-risk elderly patients in Department of orthopedics for lower limb surgery in the implementation of combined spinal epidural anesthesia can accelerate postoperative recovery,to ensure the safety of anesthesia,can be popularized in clinical application.
