消毒与灭菌后口腔科器械上血液传播性病毒标志物监测报告

目的了解消毒与灭菌后口腔器械上血液传播性病毒标志物存活情况,以加强口腔科医院感染防控措施。方法采用现场采样,通过酶联免疫吸附试验,对大同地区49所医疗机构口腔科和口腔门诊消毒后口腔器械进行了检测。结果经对14种口腔器械244份样品进行了检测,共检出血液传播性病毒标志物阳性38份,总阳性率为15.57%。在38份阳性标本中,检出乙型肝炎表面抗原阳性28份,阳性率为11.48%;检出丙型肝炎标志物(抗-HCV)阳性10份,阳性率为4.10%。结论大同市口腔医疗器械上血液传播性病毒标志物检出率较高,提示口腔器械消毒与灭菌处理效果不可靠,应加强口腔医疗器械消毒管理。

MONITORING REPORT ON BLOOD TRANSMIT VIRUS MARKERS ON STOMATOLOGICAL INSTRUMENTS AFTER DISINFECTION AND STERILIZATION

Objective To know the survival of blood transmit virus markers on stomatological instruments after disinfection and sterilization,in order to strengthen prevention and control measures of hospital infection in stomatological department.Methods Field sampling and ELISA method were used to detect stomatological instruments after disinfection and sterilization in 49 hospitals in Datong.Results 244 samples and 14 types of instruments were tested,of which 38 were blood transmit virus markers positive,the positive rate was 15.57%.Of 38 positive samples,28 samples was HBsAg positive,positive rate is 11.48%;10 samples was anti-HCV positive,positive rate was 4.10%.Conclusions Positive rate of blood transmit virus markers on stomatological instruments was high,which show disinfection and sterilization effect is not reliable.We should strengthen the management of stomatological instruments disinfection.
