口腔科HBsAg污染情况及消毒的调查研究

A Study on the HBsAg Contamination in Stomatology Department and Its Disinfection

对门诊口腔科HBsAg污染情况的调查表明,口腔科医生手的污染较其它科医务人员高。用0.1％过氧乙酸泡手效果确切,与用肥皂洗手相对照两者效果有显著性差别。器械中牙钻的污染率为25％,经洗必泰醇+戊二醛擦试;洗必泰+瞬间紫外线照射及福尔马林熏蒸12小时三种方法比较,效果无显著性差别,三种方法的效果均不够满意。口腔镜、车针等可以浸泡消毒的器械以2％戊二醛的效果最好。建议建立定期的监测监督制度,以有效地防止HBV的医院内感染。

We have examined the HBsAg contamina-tion situation of day-use instruments contamina-tion situation of day-use instruments and Doctor's hands and faces in Stematology de-partment and compared the efficacy of differ- ent disinfection procedures in destroying HBsAg on instrumchts. The results indecated that the HBsAg positivity (by ELISA) of Doctor's hands and faces were 31.5% and 35.2% respectively. It was found that 0.1% acetic acid peroxide gave more efficacy in hand washing than washing with soap. Dental bur contaminated by HBsAg was 25%, and it can not be satisfactorily destroyed by chlorhexidine+glutaraldehyde or N-1200 extraviolete apparatus or formalin evaporation, 2% glutaraldehyde was only effective disinfectant for mouth mirror, needles and other instruments that could be immersed in it.
