目的灭菌器内整锅灭菌物品出现严重湿包现象，通过案例，分析发生湿包的原因，提出控制湿包的对策。方法采用卫生部《消毒技术规范》规定，灭菌包裹含水量≤3%（手感干燥），＞6%视为湿包，对2014年7月～2016年2月脉动真空压力蒸汽灭菌器灭菌1577锅次，10000个灭菌包，BD试验452次，进行观察分析。结果灭菌器内整锅灭菌物品出现严重湿包现象，主要见于设备因素：①控制面板上的温度测量仪发生偏差，BD测量温度无法达到相应温度，导致BD试验包整个包裹全部浸湿；②疏水阀堵塞，冷凝水排出不通畅，干燥效果不佳，灭菌器内整锅灭菌物品出现严重湿包现象；其他原因引起湿包现象仅仅是手感潮湿。采取控制措施后严重湿包现象由控制前的14.4‰降至4.2‰，差异有统计学意义（χ2=28.23，P＜0.05）。结论找到湿包发生的原因，实施相应干预措施，可有效预防湿包现象。

[Abstract]Objective To analyze the causes of wet bags and come up with the measures to control the wet bags through case study since severe wet bag happens to all the sterilization staffs in the sterilizer.Methods Based on the regulations of Technical Standard for Disinfection of Ministry of Health，the water content of sterilization package should be≤3%and＞6%was seen as the wet bag.The high vacuum autoclave with pulsing system for 1577 times with 10000 sterilization package and BD experiments for 452 times from July 2014 to February 2016 were observed and analyzed.Results Severe wet bags were occurred to all the sterilization staffs in the sterilizer which was mainly caused by the devices:（1）Deviation was occurred to the temperature measuring instrument of the control panel，which led to that the BD measuring temperature was not as high as the standard temperature therefore the whole BD package was wet.（2）The drain valve was blocked and the discharge of condensate water was not smoothly and the effect of dry was not acceptable therefore the sterilization staffs were all wet.The wet bags caused by other reasons were just wet felt by the hands.After control measures，the severe wet bags decreased to 4.2‰from 14.4‰with statistical significance of the differences（χ2=28.23，P＜0.05）.Conclusion Finding out the causes of wet bags and taking correspondent intervention measures can effectively prevent the occurrence of wet bags.

湿包是指包裹在灭菌后的重量比灭菌前高出3%，此种现象称之为湿包现象。湿包产生的主要原理是蒸汽与冷的灭菌物品相遇或热的灭菌物品与冷空气相遇，形成水滴，当这些水不能被排出或重新蒸发时，就形成了湿包。近年来国内外非常关注湿包问题，灭菌包出现湿包时，灭菌包内的潮湿水分由于虹吸的原理可形成一条向外通道，为外界微生物进入提供条件，导致灭菌物品可能被污染。……
