基层医疗机构压力蒸汽灭菌器灭菌效果现况调查

Investigation on sterilization effect of pressure steam sterilizers in basic medical institutions

目的了解基层医疗机构压力蒸汽灭菌器使用及其灭菌效果,为感染防控提供依据。方法采用生物监测的方法对134所基层医疗机构的压力蒸汽灭菌器进行调查。结果共调查138台灭菌器,82.61%容量≤60 L;口腔诊所多用抽真空台式灭菌器并有干燥程序;社区中心/卫生院多用下排或立式无干燥灭菌器,湿包多见。灭菌效果合格率为81.88%,灭菌器合格率为86.96%,灭菌器合格率有差异,手提式<立式<台式<卧式;89.13%的灭菌器从未做过生物监测。结论基层医疗机构压力蒸汽灭菌生物监测及灭菌质量监管未落实,应引起有关部门重视,加强灭菌器操作培训和灭菌质量监管。

Objective To realize the use and sterilization effect of pressure steam sterilizers in basic medical institutions and provide scientific evidence for infection control. Methods Biomonitoring effect was used to investigate the pressure steam sterilizers including 134 basic medical institutions. Results A total of 138 pressure steam sterilizers were investigated and 82. 61% of the sterilizers had a capacity of less than 60 L. Most dental clinics used vacuum-pumping benchtop sterilizers equipped with drying procedure. Healthcare centers of community mostly used air exhaust sterilizers with no drying procedure,which led to wet sterilized pack commonly. The results of biomonitoring have shown that 81. 88% of the sterilizing samples met standard sterilization effect and 86. 96% of the sterilizers reached qualified sterilization effect. Horizontal type of sterilizer had a better sterilization effect than benchtop,vertical type and portable type. Sterilizers which were never monitored before accounted for 89. 13%. Conclusion Biomonitoring of sterilizers and quality of sterilization were not performed and supervised effectively. Public health administration need put efforts to strengthen knowledge trainingandreinforce the power of supervision.
