本文对５２５例先天性心脏病术后早期患儿进行下呼吸道分泌物细菌检测和药物敏感试验，其中２１例培养出致病菌。这２１例中绿脓杆菌１２例（５７％），感染发生率４．０％。由于早期发现致病菌，及时采用中西医结合治疗，感染死亡率为零。

The monitoring and treatment in nosocomical infection in infants after open heart surgery were reported in this paper. Bacterial examinations of the secretion from lower respiratory tract were carried out in 525 infants aged 2 months to 6 years during the early period after open heart surgery from April, 1991 to March, 1992 at this hospital. Twenty-one cases were found to have lower respiratory tract infection, with positive pathogenic culture. Majority of the infected cases were due to gram-negative organisms ,including 12 cases infected with pseudomonas aeruginosa(57%). The total rate of postoperative infection was 4. 4%. The rate of infection was related to age ,kind of disease ,cardiopulmonary by pass time ,complications ,endotracheal intubation time,resistance of the pathogenic organisms to antibiotics, etc. With early treatment by antibiotics combined with Chinese traditional herbs ,all of the patients recovered from the infection.
