消化内镜消毒中邻苯二甲醛更换频率的探讨

Exploration on frequency of replacement of ortho-phthalaldehyde in digestive endoscopy disinfection

目的为确保消化内镜消毒时邻苯二甲醛的消毒效果,探索该消毒剂合理的更换频率。方法分别监测邻苯二甲醛使用中的浓度、染菌量和消毒后消化内镜微生物学指标,通过初步及确证试验,确定邻苯二甲醛有效使用频数。结果邻苯二甲醛用于胃镜消毒时有效频数为102次,用于肠镜消毒时有效频数为85次。结论将使用时间与使用频率作为更换邻苯二甲醛的依据更具科学性,且临床实践操作性较强。

Objective To ensure the disinfection effect of phthalaldehyde,explore a reasonable frequency in digestive endoscopy disinfection. Methods To monitor the concentration,the contaminating bacteria count of using ortho-phthalaldehyde and digestive endoscopic which disinfected in the initial test period and determine test period,to determine the effective use frequency of ortho-phthalaldehyde,and then the accuracy is verified through the verification period. Results The effective frequency of ortho-phthalaldehyde for gastroscopy disinfection was 102,when for enteroscopy disinfection was 85.Conclusion It is more scientific and operational when combined the time and frequency as a basis for replacement of ortho-phthalaldehyde.
