目的了解医疗机构中过氧化氢低温等离子体灭菌器及其生物指示物的应用状况。方法采用问卷调查和现场查看形式,对江苏省部分医疗机构使用中的过氧化氢低温等离子体灭菌器及其生物指示剂生物负载进行调查与测试。结果共调查江苏省市级医疗机构97家,其中67家拥有过氧化氢低温等离子体灭菌器,拥有率为88.16%。过氧化氢低温等离子体灭菌器的灭菌效果均采用生物指示剂进行定期监测,所使用的生物指示剂的回收菌量合格率为35.48%。结论江苏省医疗机构过氧化氢低温等离子体灭菌器拥有率较高,其灭菌效果监测专用生物指示剂多数不符合标准,亟待规范。
Objective To understand the application of hydrogen peroxide low temperature plasma sterilizer and its biological indicators in medical institutions. Methods The questionnaire survey and on-site inspection were used to investigate and test the bio-load of hydrogen peroxide low-temperature plasma sterilizer and its biological indicators in some medical institutions in Jiangsu Province. Results A total of 97 municipal-level medical institutions in Jiangsu Province were surveyed, of which 67 possessed hydrogen peroxide plasma sterilizer with a rate of 88.16%. The sterilizing effects of hydrogen peroxide plasma sterilizers were monitored periodically with biological indicators. The qualified rate of the recovered biological indicators used was 35.48%. Conclusion The ownership rate of hydrogen peroxide low temperature plasma sterilizer in medical institutions in Jiangsu Province is relatively high. Most of the biological indicators for monitoring the sterilization effect do not meet the standards and are in urgent need of standardization.
