美罗培南两步输注法治疗老年人慢性阻塞性肺疾病并铜绿假单胞菌肺炎疗效分析

Clinical evaluation of a two-step infusion therapy with meropenem against nosocomial multi-drug resistant Pseudomonas aeruginosa infections in elderly patients with chronic obstructive pulmonary disease

目的：评价美罗培南两步输注法治疗老年人COPD并院内获得性多重耐药铜绿假单胞菌肺炎的疗效。方法选取老年COPD并院内获得性多重耐药铜绿假单胞菌肺炎患者112例，数字表法随机分为两组，各56例，观察组采用两步输注法，第一步，在30 min内把单次剂量中的一半药物快速滴注完；第二步，把单次剂量的剩余一半药物在2．5 h内持续缓慢滴注。对照组采用美罗培南常规30 min滴注法。观察两组患者的临床疗效及细菌学疗效。结果观察组、对照组有效率分别为82．2％（46／56）、57．1％（32／56），差异有统计学意义（χ2＝10．185，P＜0．05）；观察组、对照组细菌清除率分别为75．0％（42／56）、46．4％（26／56），差异有统计学意义（χ2＝10．265，P＜0．05）。结论使用美罗培南两步输注法治疗老年人COPD并院内获得性多重耐药铜绿假单胞菌肺炎的疗效优于传统输注方案。

Objective To evaluate the efficacy of a two-step infusion therapy with meropenem against noso-comial multi-drug resistant Pseudomonas aeruginosa infections in elderly patients with chronic obstructive pulmonary disease.Methods 112 elderly patients with nosocomial multi-drug resistant Pseudomonas aeruginosa infections and chronic obstructive pulmonary disease were randomized into two groups：two-step infusion therapy group （ rapid first-step infusion in 30 minutes and slow second-step infusion in 2.5 hours） and traditional 30 minutes infusion therapy group.The antibiotic clinical efficacy and bacteriological efficacy were observed between two groups .Results The clinical efficacy of observation group and control group were 82.2%（46/56） vs 57.1%（32/56）.The difference was statistically significant（χ2 =10.185,P＆lt;0.05）;The bacteriological efficacy of observation group and control group were 75.0%（42/56） vs 46.4%（26/56）,The difference was statistically significant （χ2 =10.265,P＆lt;0.05）. Conclusion The clinical efficacy and bacteriological efficacy of two-step infusion therapy with meropenem against nosocomial multi-drug resistant Pseudomonas aeruginosa infections in elderly patients with chronic obstructive pulmo -nary disease were superior to the traditional therapy .
