Bacterial contamination of gastrointestinal fibre-endoscopes is a potential source of clinically significant infection. Aqueous 2% alkaline glutaraldehyde adequately disinfects fibre-endoscopes but may cause serious sensitivity reactions among endoscopy staff. A new 'closed-system' disinfecting apparatus is described that disinfects with glutaraldehyde for 30 minutes before an endoscopy session, for two minutes between patient procedures, and for 10 minutes before storage. Bacteriological cultures of the endoscope after disinfection were virtually sterile. Extremely low glutaraldehyde vapour levels were detected by gas chromatography in endoscopy room air during disinfection procedures. This relatively simple apparatus offers rapid, effective, and safe disinfection of fibre-endoscopes.
胃肠道纤维内窥镜的细菌污染是临床上重要感染的潜在来源。2%的碱性戊二醛水溶液能充分消毒纤维内窥镜，但可能会在内镜检查人员中引起严重的过敏反应。本文描述了一种新的“封闭系统”消毒装置，该装置在每次内镜检查前用戊二醛消毒30分钟，在患者检查之间消毒2分钟，在储存前消毒10分钟。消毒后的内窥镜细菌培养结果几乎无菌。在消毒过程中，通过气相色谱法在内镜检查室空气中检测到极低的戊二醛蒸汽水平。这种相对简单的装置能对纤维内窥镜进行快速、有效且安全的消毒。
