目的:研究分析不同低浓度罗哌卡因硬膜外麻醉对老年腰椎间盘突出症患者椎间孔镜治疗的效果.方法:筛入患者为我院收治的老年性腰椎间盘突出40例患者作为研究对象,根据随机数字表格法,将其分为A、B两组,分别采用不同浓度罗哌卡因进行硬膜外神经阻滞麻醉,观察两组患者镇痛效果及麻醉情况.结果:B组患者神经根刺激、核髓摘除阶段VAS评分优于A组,组间数据值比较,有统计学意义(P＜0.05);而其他手术操作阶段两组疼痛评分比较,无统计学意义(P＞0.05);两组患者硬膜外腔应用罗哌卡因后T3、T4时改良Bromage评分比较,无统计学意义(P＞0.05);B组麻醉优良率高于A组,但两组对比,无统计学意义(P＞0.05).结论:两种不同低浓度罗哌卡因麻醉效果良好,但0.2％浓度罗哌卡因麻醉效果及安全性更佳.","Objective To study the effect of different low-dose ropivacaine epidural anesthesia on the treatment of elderly patients with lumbar disc heiation. Methods A total of 40 patients with senile lumbar disc heiation admitted to our hospital were enrolled in this study. According to the random number table method, they were divided into A and B group, wich were treated with different concentrations of ropivacaine epidural anesthesia anesthesia, and then the analgesic effect and anesthesia were observed in two groups of patients. Results Compared with group A, the VAS scores of nerve root stimulation and nucleotomy in group B were better than those in group A (P＜0.05). The pain scores of the two groups were not statistically significant (P＞0.05). There was no significant difference between the two groups (P＞0.05). The excellent rate of anesthesia in group B was higher than that in group A, but there was no statistical difference between the two groups Significance (P＞0.05). Conclusion Two different low-dose ropivacaine anesthesia works well, but 0.2％ ropivacaine has better anesthesia and safety.
