Abstract

In this study the extent of bacterial contamination in a nonrebreathing inhalation sedation unit was determined. Bacteriologic cultures of different areas of the Quantiflex MDM machine were obtained during successive week-long courses in conscious sedation at this institute. Results of the bacteriologic cultures revealed the microbial contamination of nasal hoods before and after attempted disinfection with alcohol. The other areas of the unit were shown to be free of bacteria. Since attempted alcohol disinfection of nasal hoods was found to be ineffective, autoclave sterilization is recommended.

摘要

在本研究中，测定了非重复吸入镇静装置中的细菌污染程度。在该机构进行的连续为期一周的清醒镇静过程中，对Quantiflex MDM机器的不同区域进行了细菌培养。细菌培养结果显示，在用酒精进行消毒前后，鼻罩均存在微生物污染。该装置的其他区域未发现细菌。由于发现酒精对鼻罩的消毒尝试无效，建议采用高压蒸汽灭菌法。
