戊二醛为合成的强消毒药,毒性较低,杀灭微生物的作用范围广,对病毒和芽胞也有效。临床用于金属医疗器械及内窥镜等精密仪器的消毒。因碱性戊二醛消毒作用比酸性强,临床需将PH值调至碱性条件下使用,但碱性戊二醛溶液稳定性差,会慢慢聚合而使消毒能力减弱。本文对碱性戊二醛在临床使用的半个月内含量变化进行测定,以供临床参考。 Glutaraldehyde is a synthetic strong disinfectant with low toxicity, a wide range of action to kill microorganisms, and effective against viruses and spores. Clinical use of metal medical devices and endoscopes and other precision instruments disinfection. Due to the alkaline glutaraldehyde disinfection than acidic, the clinical need to adjust the PH value to alkaline conditions, but the stability of alkaline glutaraldehyde solution is poor, will gradually reduce the disinfection of polymerization. In this paper, the content of alkaline glutaraldehyde in clinical use within half a month to determine changes for clinical reference.
