摘　　要：目的　探讨新生儿机械通气 (MV)并下呼吸道感染的临床特点。方法　对 6 8例 92份下呼吸道分泌物进行培养及药敏试验 ,且对并发下呼吸道感染率与胎龄、体重、机械通气持续时间等因素进行分析。结果　感染率为 6 1.76 % ,MV时间越长 ,感染率越高 ,以鲍曼不动杆菌、铜绿假单胞菌、肺炎克雷伯杆菌为主要致病菌 ,药敏对大多数常用抗生素、甚至第 3代头孢菌素多不敏感。结论　感染率与出生体重和MV持续时间有关 ,与胎龄无关 ;革兰阴性杆菌为主要致病菌 ,耐药率高 ,应积极防治。Objective To explore the infants with mechanic ventilation-associated lower respiratory tract infection clinical characteristic.Methods To analysis 68 cases 93 portions secretions colture and drug sensitive test and the related factors among infection rate and infant age,born weight,ventilation last time.Results Infection rate is 61.76 %,mechanic ventilation more long and infection rate more higher.Baumanii Pseudomonsa and Klebsialla are main germs.Conclusions The infection rate connect with born weight and ventilation last time,but not related with infant age.Gram-Negative is main germ,resistance rate high,we should prevent and treat.
