【摘要】 为减少医源性传播，我们于１９８６年和１９９３年两次对医院环境、医疗用品进行了采样，应用超离心浓缩后放射免疫方法检测ＨＢｓＡｇ。在１９８６年采集的４２份样品中，有４７．６％的样品检出了ＨＢｓＡｇ，污染严重。根据调查结果，制定了７项干预措施，并加强了监督检查。１９９３年再次在医院进行了采样检查，结果在３３份样品中，仅在未消毒的医疗器械中查出了３份ＨＢｓＡｇ，检出率降为３．０％，医院感染状况明显好转。更多还原

【Abstract】 In order to reduce introgenic Infection spread , we sampled environment out of hospital, medical netessities in 1986 and 1993. Through hypercentrifagal concentration, These samples were tested by RIA method. In 42 samples taken in 1986, 47.6%of them were determined HBsAg, The Contamination is very serious,So we made out Seven intervened measures and strengthened supervision and inspection , while we took samples twice in hospetal in 1993,Onlg 3 HBsAg were found in unsteritiged medical instrumente in 33 samples. The Contaminated rate decreased to 3.0%the situation of hospital contamination has improsed distinetly and the spread of introgenic infection has decreaced.更多还原
