问:目前新洁尔灭广泛用于医院消毒,为何近年提出限制该消毒剂的使用范围?(江西读者周晓珊) 答:新洁尔灭是一种季铵盐类消毒剂,属阳离子表面活性剂。我国自六十年代生产以来,因其水溶液透明,无刺激性,对物品腐蚀性小,曾被誉为一种理想的消毒剂。随着消毒剂杀菌检测方法的完善,逐渐发现新洁尔灭等季铵盐类消毒剂尽管抑菌作用很强,但杀菌谱较窄。例如,虽对革兰氏阳性菌的杀灭效果较好,而对绿脓杆菌等革兰氏阴性菌的作用较差,对结核杆菌和细菌芽胞则基本无效,就病毒而言,该消
Q: At present, benzalkonium bromide is widely used in hospital disinfection, why in recent years proposed to limit the use of the disinfectant? (Jiangxi readers Zhou Xiaoshan) A: Bromogeramine is a quaternary ammonium salt disinfectant, is a cationic surfactant. Since our production in the 1960s, it has been praised as an ideal disinfectant because of its transparent, non-irritating aqueous solution and small corrosiveness to articles. With the improvement of sterilizing and sterilizing detection methods, it has gradually been found that the quaternary ammonium disinfectants such as benzalkonium bromide have a strong bacteriostatic effect but have a narrower spectrum of sterilization. For example, although Gram-positive bacteria kill better, and Pseudomonas aeruginosa and other Gram-negative bacteria less effective against Mycobacterium tuberculosis and bacterial spores are basically ineffective, the virus, the consumer
