目的：观察唑来膦酸用于不同病程急性椎体骨折性疼痛的疗效。方法：选取急性胸腰椎压缩性骨折患者207例，按照随机数字表法分为试验组（107例）与对照组（100例）。对照组患者给予碳酸钙1200 mg/d及双氯芬酸钠缓释片75 mg/d；试验组患者在对照组基础上给予唑来膦酸5 mg加入5％葡萄糖溶液100 ml中静脉滴注15～30 min。结果：治疗后，两组患者视觉模拟评分（VAS）法评分均明显下降，且试验组较对照组下降更显著，差异有统计学意义（P＜0.05）；病程≤1个月患者与1个月＜病程≤2个月患者VAS评分比较，差异无统计学意义（P＞0.05）。治疗4 d，病程≤1个月和1个月＜病程≤2个月的患者与病程＞2个月的患者VAS评分比较，差异有统计学意义（P＜0.05）；治疗1周后，病程≤1个月和1个月＜病程≤2个月的患者与病程＞2个月的患者VAS评分比较，差异有统计学意义（P＜0.05）。结论：唑来膦酸可部分缓解急性椎体骨折性疼痛，早期应用镇痛效果更明确。%OBJECTIVE:To observe therapeutic efficacy of zoledronic acid in the treatment of acute pain of vertebral compres-sion fractures during different courses. METHODS:207 patients with acute thoracic or (and) lumbar vertebral compression frac-tures were selected and randomly divided into trial group(107 cases)and control group(100 cases). Control group was given calci-um carbonate(1 200 mg/d)diclofenac sodium sustained-released tablet(75 mg/d).Trial group was additionally given zoledronic ac-id 5 mg added into 5%Glucose solution 100 ml,intravenous dripping for 15-30 min,on the basis of control group. RESULTS:Af-ter treatment,VAS score of two group decreased significantly,and trial group the decrease was more significant than control group,with statistical significance (P0.05);after 4d treatment,there was statistical significance in VAS score between course≤one month and one month 0.05);after one week,there was statistical significance in VAS score between one month 2 months (P<0.05).CONCLUSIONS:Zoledronic acid may partly alleviate the pain of acute vertebral fractures,the analgesic effect is more clear in early stage.
