为了解医院内乙型肝炎表面抗原(HBsAg)污染的情况,于1989年和1990年对5所医院进行了调查。调查中、用棉拭子涂抹法对医院内各科室所用医疗器械与物品采样。样品经ELISA法测定,S/N值≥2.1,中和试验S/N值<1.6倍,同时两者S/N值之差在2倍以上者为阳性。共采集各种医疗器械及物品样本440份,HBsAg阳性率为14.32％。各物品的阳性率分别为:牙科器械14.29％(5/35),血红蛋白吸管
To understand the contamination of hepatitis B surface antigen (HBsAg) in the hospital, five hospitals were surveyed in 1989 and 1990. In the survey, samples of medical devices and articles used in various departments of the hospital were sampled with cotton swab smear method. Samples were determined by ELISA, S / N value ≥ 2.1, neutralization test S / N value <1.6 times, while the difference between the two S / N values were positive for more than 2 times. A total of 440 samples of various medical devices and articles were collected. The positive rate of HBsAg was 14.32%. The positive rates of each item were: dental equipment 14.29% (5/35), hemoglobin pipette
