摘 要:分析使用替加环素治疗医院获得性肺炎(HAP)的临床疗效及用药合理性。
通过阅读相关文献对国内外研究进展进行梳理和总结。
替加环素治疗HAP属超说明书用药,国内外学者对此有不同看法,国外认为高剂量替加环素治疗HAP是必需的,而国内有学者赞同此看法也有认为替加环素与其他抗菌药效果相当并不必要。
替加环素治疗HAP的是一种选择,但应该更加重视替加环素的规范使用,为重症感染的治疗创造更多机会。

Through reading the relevant literature, the research progress at home and abroad is sorted out and summarized. There are different opinions among scholars at home and abroad that tegacycline is a kind of over-prescribed drug for HAP treatment. Foreign scholars think that high-dose tegacycline is necessary for HAP treatment, while domestic scholars agree with this view and think that the effect of tegacycline and other antibiotics is quite unnecessary. Tigacycline is an option for HAP treatment, but more attention should be paid to the standardized use of tigacycline to create more opportunities for the treatment of severe infections.Key Words: Tigacycline;Hospital-acquired pneumonia;Ventilator-associated pneumonia; Ultra-manual medication医院获得性肺炎(hospital-acquired pneumonia,HAP)是指入院ge;48h后发生且入院时似乎并没有处于潜伏期的肺炎,其中还包括呼吸机相关性肺炎(ventilator-associated,VAP)[1]。
在医院获得性感染中HAP造成死亡原因比例较高,据估计HAP相关死亡率为20%-50%[2-3]。
HAP和VAP患者中最常见的病原体是鲍曼不动杆菌、铜绿假单胞菌和肠杆菌科细菌。
其中,鲍曼不动杆菌多重耐药(Multiple resistant bacteria, MDR)和广泛耐药(Extensively drug resistant bacteria, XDR)比率高达82%和51.10%,碳青霉烯类药物耐药菌株高达67.30%,其中肺炎克雷伯杆菌中MDR比率约44.70%[4]。
耐药菌的出现,让临床诊治变得困难重重。
2005年6月,替加环素(Tigecycline)第一个被美国食品和药品监督管理局(Food and Drug Administration,FDA)批准临床使用,是新一代甘氨酰四环素类抗菌药物。
