【摘要】 本文总结了近４年因呼吸衰竭接受机械通气患者下呼吸道病原菌分布和耐药性。１４５株病原菌中，Ｇ－杆菌占７２４％，霉菌占１６６％，Ｇ＋球菌占１１０％。Ｇ－杆菌中，以铜绿假单孢菌为主，占Ｇ－杆菌的６１％。Ｇ－杆菌对１５种抗生素的耐药率为２８％～１００％，铜绿假单孢菌对１５种抗生素的耐药率为２８２％～１００％。根据药敏结果，对因呼吸衰竭接受机械通气患者抗生素的使用进行了讨论更多还原

【Abstract】 In the paper,the distribution and drug-resistance of pathogenetic germs from lower respiratory tract of patients with respiratory failure were studied.The ratios of gram-negative bacillus,gram-postive coccus and mould in 145 strains germs were 72.4%,11.0% and 16.6%,respepectively.Pseudomonas aeruginosa was 61% of gram-negative bacilli.The drug-resistant rates of 15 antibiotics of gram-negative bacilli were 28%～100%,and the drug-resistance of Pseudomonas aeruginose were 28.2%～100%. The usage of antibiotics for respiratory failure patients with receiving mechanical ventilation was discussed.更多还原
