早产儿机械通气相关性呼吸道感染病原菌分析

【摘要】 目的探讨早产儿机械通气相关性呼吸道感染病原菌谱、病原菌的药敏情况及防治措施。方法对39例患者机械通气相关性呼吸道感染的早产儿呼吸道分泌物进行培养。结果39例61份标本中分离出细菌和真菌52份,培养结果阳性率85.25%,其中依次以溶血性链球菌(23.08%)、金黄色葡萄球菌(7.69%)、表皮葡萄球菌(7.69%)所占比例最高,对万古霉素敏感。结论早产儿机械通气相关性呼吸道感染病原菌以G+菌为主,对万古霉素敏感。更多还原

【Abstract】 Objective To study the distribution and sensitivity of pathogenic bacteria and prevention and cure methods in ventilator-associated respiratory infection with preterm infants.Methods 39 Preterm infants who suffered from ventilator-associated respiratory infection,whose respiratory tract excretion were cultured.Results 52 of 61 samples were bacteria and fungi,positive ratio of cultivation was 85.25%.The predominant pathogens were hemolyticstreptococcus(23.08%),staphylococcus aureus(7.69%) and staphylococcus epidemidis(7.69%).Those pathogens were sensitive to vancomycin.Conclusion The gram-postive bacterium is main pathogens in ventilator-associated respiratory infection with preterm infants, which is sensitive to vancomycin.更多还原
