The level of cleanliness in the laminar airflow room of Tokai University Hospital was studied. Bacteriological monitoring of the protected isolation ward during occupancy by patients revealed that it was kept at class 100 according to NASA standards. The laminar airflow room was decontaminated with formaldehyde gas by means of a gas generator which we made. This decontamination method was shown to be easy and safe to handle, and stable in its effects. Up to December 1981, 54 patients with acute leukemia were treated in the protected isolation ward. The incidence of infection in patients with acute leukemia was lower in the protected isolation ward than in the conventional ward. No respiratory infection was observed in the protected isolation ward. These results demonstrated statistically significant advantages of the use of the laminar airflow room for prevention of infection.
对东海大学医院层流空气房间的清洁程度进行了研究。对患者入住期间的保护性隔离病房进行细菌学监测发现，根据美国国家航空航天局（NASA）标准，该病房保持在100级。使用我们自制的气体发生器，用甲醛气体对层流空气房间进行净化处理。结果表明，这种净化方法操作简便、安全，效果稳定。截至1981年12月，有54例急性白血病患者在保护性隔离病房接受治疗。急性白血病患者在保护性隔离病房的感染发生率低于传统病房。在保护性隔离病房未观察到呼吸道感染。这些结果证明了使用层流空气房间预防感染具有统计学上的显著优势。
