【摘要】：目的了解西安市医疗机构压力蒸汽灭菌现状,为压力蒸汽灭菌的监测和质量管理提供依据。方法以2012—2014年西安市属医疗机构的消毒供应中心为研究对象,分别采用物理、化学、生物监测法对其压力蒸汽灭菌器进行综合评价。结果共监测西安市135所医疗机构,包括40所三级医疗机构和95所二级及以下医疗机构。共收集样本540份,合格样本454份,总合格率为84.07%。其中三级医疗机构压力蒸汽灭菌监测合格率为93.13%,高于二级及以下医疗机构的80.26%,差异有统计学意义(χ~2=13.91,P0.01)。化学PCD和生物标准测试包的合格率:三级医疗机构为100%,二级及以下医疗机构90%。二级及以下医疗机构记录表格中的温度合格率为88.42%,但实测温度合格率仅为38.95%,实测温度合格率远低于三级医疗机构的72.50%,差异有统计学意义(χ~2=12.68,P0.01)。各年度压力蒸汽灭菌器实测温度134℃的比率均较低,而132℃的比率维持在50.00%左右,实测温度与记录温度相差-4~1℃,温度差为-2.5~0.5℃的占80.00%,主要不合格温度集中在130~131℃,占82.61%。结论西安市不同级别医疗机构压力蒸汽灭菌效果差异较大,物理监测措施不规范,应加强重点部门的物理参数监督,保证医疗机构灭菌质量,减少医源性感染的发生。
[Abstract]:Objective to understand the current situation of pressure steam sterilization in medical institutions in Xi'an, and to provide the basis for monitoring and quality management of pressure steam sterilization. Methods the disinfection and supply centers of medical institutions in Xi'an from 2012 to 2014 were used as the research objects and physical and chemical methods were used respectively. Results 135 medical institutions in Xi'an were monitored, including 40 tertiary medical institutions and 95 second-level and below. 540 samples were collected and 454 qualified samples were collected. The total qualified rate was 84.07. The qualified rate of pressure steam sterilization monitoring in tertiary medical institutions was 93.13, which was higher than 80.26 in secondary and lower medical institutions, and the difference was statistically significant (蠂 ~ 2 ~ 2 ~ 13.91 ~ (1) P _ (0.01)). The qualified rate of chemical PCD and biological standard test package was: level 3 medical machine. The qualified rate of temperature in the record form of level 2 and below medical institutions is 88.42, but the qualified rate of measured temperature is only 38.95. The qualified rate of measured temperature is much lower than 72.50 of the third level medical institution. The difference is statistically significant. The ratio of measured temperature of pressure steam sterilizer to 134 鈩，
