The postantibiotic effect (PAE), sub-MIC effect (SME), and postantibiotic sub-MIC effect (PASME) of imipenem on Pseudomonas aeruginosa were investigated with an in vitro dynamic model reproducing in vivo elimination kinetics of the antibiotic. The PASMEs were constantly longer than the corresponding SMEs, but differences between them were not statistically significant. Both PASMEs and SMEs were initially bactericidal and were significantly longer than PAEs. The mean values of both PASMEs and SMEs were over 12 h. SMEs appear to be more relevant for the bacterial growth kinetics than PAEs.
采用一种能再现抗生素体内消除动力学的体外动态模型,研究了亚胺培南对铜绿假单胞菌的抗生素后效应(PAE)、亚抑菌浓度效应(SME)和抗生素后亚抑菌浓度效应(PASME)。PASME持续时间始终长于相应的SME,但两者之间的差异无统计学意义。PASME和SME最初均具有杀菌作用,且显著长于PAE。PASME和SME的平均值均超过12小时。与PAE相比,SME似乎与细菌生长动力学更相关。
