中文摘要:
      目的:监测几种临床常用抗菌药物对肺炎克雷伯杆菌最低抑菌浓度(MIC)变化情况,在临床工作中帮助选择合理的初始化 抗菌治疗方案。方法:本研究选择哌拉西林他唑巴坦、头孢哌酮舒巴坦、拉氧头孢钠、左氧氟沙星及头孢他啶5 种常用的抗革兰 氏阴性杆菌感染的治疗药物作为初始经验性治疗方案,使用随机法将5 种抗菌方案分配到5 个观察组,5 个观察组于 2011.07-2012.07 间各自采集HAP 患者痰标本,筛选出其中ESBLs(-)肺炎克雷伯杆菌资料,并于2012.08-2013.08 间分别使用1 种拟定的抗菌治疗方案进行HAP的初始化治疗。使用Crystal Ball 软件进行蒙特卡罗模拟计算上述5 种药物常用方案的两个阶 段的累计反应分数(CFR),比较其效果。结果:(1)在按规定方案治疗1 年后,头孢哌酮钠舒巴坦、哌拉西林他唑巴坦、拉氧头孢 钠、左氧氟沙星组有效率改变均无统计学意义,头孢他啶组固定初始化治疗1 年后有效率下降,有统计学意义(P=0.037);(2 )对各 科室初始化方案再次进行了蒙特卡罗模拟,对比后发现头孢他啶方案CFR 较前下降明显,其余方案CFR 差异小。结论:蒙特卡 罗模拟法可计算出用药方案达到药效学指标的概率,以CFR 为标准可以更为直观的选择经验性治疗方案,并有效的监测细菌耐 药性的变化。
英文摘要:
      Objective:Monitoring Minimum inhibitory concentration (MIC)changes of Klebsiella pneumoniae of several antimicrobial agents which commonly used in clinical, to help making a reasonable choice of initializing antimicrobial treatment programs in clinical work.Methods:In this study, piperacillin-tazobactam, cefoperazone sulbactam, Latamoxef sodium, levofloxacin and ceftazidime five kinds of commonly used anti-Gram-negative bacilli infections drugs as initial empiric therapy, were assigned to five observation groups by random method.Collected sputum samples of patients with HAP in each observation group at 2011.07-2012.07, then screened out of which ESBLs (-) Klebsiella pneumoniae data and used one intended antimicrobial initialization treatment of HAP Respectively at 2012.08-2013.08. Using Crystal Ball software for Monte Carlo calculation of two-stage CFR of the above five kinds of drugs commonly used programs, and their results were compared.Results:(1) One year later, treatment efficiency in cefoperazone sulbactam group, piperacillin-tazobactam group, Latamoxef sodium group and levofloxacin group was not statistically significantly changed, while its decrease was statistically significant in ceftazidime group (P = 0.037). (2) Compared the CFR of two stages and found that of ceftazidime significantly decreased compared with the previous CFR, and others had small differences.Conclusion:Monte Carlo simulation calculates the probability of drug regimens to achieve pharmacodynamic targets. With the CFR as a standard , empiric treatment programs can be selected more visually, and change of bacterial resistance can be monitored effectively.
