From October 1987 to December 1989, bacteriological surveillance was done after open heart surgery in 100 patients with cardiovascular diseases (54 with congenital, 44 with rheumatic, and 2 with other types of heart disease). The time of bypass was 58 to 234 minutes (mean = 98.7 minutes). The positive rate of culture was 5% for blood, 40% for sputum, and 15% for pericardial drainage. Many types of bacteria were separated. Most of them were conditional pathogenic bacteria. Postoperative infection was found in 9 patients, (bacteremia in 1 and pulmonary infection in 8.) Tracheostomy was done in 5 cases. In discussion, the authors think that the low defensive ability of the patients with serious heart disease is usually further damaged by bacterial invasion after open heart surgery and that bacterial contamination should be reduced in order to prevent postoperative infection.
1987年10月至1989年12月，对100例心血管疾病患者（54例先天性心脏病、44例风湿性心脏病、2例其他类型心脏病）进行了心脏直视手术后的细菌学监测。体外循环时间为58至234分钟（平均98.7分钟）。血培养阳性率为5%，痰培养阳性率为40%，心包引流液培养阳性率为15%。分离出多种细菌，大多数为条件致病菌。9例患者发生术后感染（1例菌血症，8例肺部感染）。5例行气管切开术。在讨论中，作者认为严重心脏病患者的低防御能力在心脏直视手术后通常会因细菌入侵而进一步受损，应减少细菌污染以预防术后感染。
