摘　　要：目的比较3%双氧水、2%戊二醛、硼砂酚醛浸泡和煮沸消毒方法对气管内套管的消毒效果。方法在实验观察的基础上,分别采用上述方法对同期气管切开病人使用中的气管内套管进行消毒,并对每种方法消毒前后、4种方法消毒前、4种方法消毒后内套管染菌情况进行比较。结果4种方法消毒前内套管染菌情况均较严重,各组间比较无显著性差异(P>0.05);每种方法消毒前后内套管染菌情况显示显著性差异(P<0.01或P<0.001);4种方法消毒后内套管染菌量比较,除双氧水组与其它各组间有显著性差异外(P<0.01),其余各组间均无显著性差异(P>0.05)。结论4种方法用于气管内套管消毒均有效,其中尤以煮沸法、戊二醛浸泡法、硼砂酚醛浸泡法为佳,双氧水浸泡法稍差。2%戊二醛及硼砂酚醛浸泡可以取代传统的煮沸法用于气管内套管的消毒。Objective To compare the sterile effects of disinfecting endotracheal tubes by soaking with 3% hydrogen peroxide solution, 2% glutaral, borax phenol and formaldehyde solution and by boiling. Methods Based on experimental observation, the endotracheal tubes used in patients with tracheotomy during the same period were sterilized by soaking with 3% hydrogen peroxide solution, 2% glutaral,borax phenol and formaldehyde solution and by boiling. The germ contaminations were compared before and after disinfection respectively and mutually. Results Before sterilization, the germ contaminations were worse, without significant differences between the 4 methods (P>0.05). Compared with pre- and post- sterilization, all the methods showed significances (P<0.01 or P<0.001). Compared with sterile effects of the 4 methods, the method with hydrogen peroxide solution was significantly different from other three groups (P<0.01), which, however, had no significant differences between them (P>0.05). Conclusion The 4 methods used to disinfect endotracheal tubes are all effective, especially the methods of boiling and soaking with glutaral, borax phenol and formaldehyde solution. Soaking with 2% glutaral,borax phenol and formaldehyde solution can take the place of boiling in sterilizing endotracheal tubes.
