复方次氯酸钠消毒剂用于口腔器械消毒的实验研究

目的研究复方次氯酸钠消毒剂对医院口腔器械消毒的效果。方法采用口腔器械模拟现场消毒试验方法对污染乙型肝炎表面抗原的灭活效果进行观察。结果用含有效氯500 mg/L以上复方次氯酸钠消毒液浸泡作用10 min,对污染到口腔器械表面的乙型肝炎表面抗原灭活率达到100%。含有效氯1000 mg/L的复方次氯酸钠消毒液连续浸泡常用口腔器械10 d未见明显腐蚀。结论本研究复方次氯酸钠消毒剂对污染到口腔器械上的乙型肝炎表面抗原具有快速的灭活效果,并且对器械基本无腐蚀。

EXPERIMENTAL STUDY ON APPLICATION OF COMPOUND SODIUM HYPOCHLORITE DISINFECTANT TO DISINFECTION OF DENTISTRY INSTRUMENTS

Objective To study the efficacy of compound sodium hypochlorite disinfectant in disinfection of oral instruments in hospital.Method Simulated on-the-spot disinfection of oral instruments was used to observe the efficacy in inactivating HBsAg contaminating the instrument.Results Immersion in the compound sodium hypochlorite disinfectant solution containing available chlorine more than 500 mg/L for 10 min achieved 100% inactivation rate of HBsAg contaminating the surfaces of oral instruments.Continuous immersion of common oral instruments in the compound sodium hypochlorite disinfectant solution containing available chlorine 1000 mg/L for 10 days did not cause obvious corrosion.Conclusions The compound sodium hypochlorite disinfectant has efficacy in quick inactivation of HBsAg on oral instruments and essentially does not corrode the instruments.
