摘　　要：目的PCD用于H2O2等离子体灭菌器效果监测的初步探讨。方法用H2O2等离子体灭菌器对不同物品进行模拟现场灭菌试验,37℃培养至设定时间后记录数据。结果止血钳头、电线外皮、生物指示物3、00 mm不锈钢短管腔和2000 mm聚四氟乙烯管腔灭菌成功,600 mm不锈钢长管腔及低温的300 mm不锈钢短管腔灭菌失败。结论H2O2等离子体灭菌需要引入PCD技术以提高监测的可靠性。OBJECTIVE To monitor the sterilization effect of hydrogen peroxide gas plasma sterilizer with process challenge defice（PCD）. METHODS Hydrogen peroxide gas plasma sterilizer was used to sterilize different material and structure items in simulation field sterilization trial. The test pieces have been cultured for 7 days at 37 ℃. Make the test records in detail. RESULTS The hemostatic forceps, surface of lines and biological indicators, as well as 300 mm stainless steels tube and 2000 mm Teflon tube were sterilized successful. But 600 mm and 300 mm stainless steels of low temperature did not past the challenge tests. The results of test surface and test lumen were inconsistent. CONCLUSIONS PCD is need to be introduced in monitoring sterilization effect of hydrogen peroxide gas plasma sterilizer.
