摘要

Abstract

Purpose,2,To quantitatively analyze the effect of starting the pressure steam sterilizer in different startup conditions on BD test results, and to provide operational suggestions for medical units.,Methods,2,When the jacket pressure of the pressure steam sterilizer reached the set value before daily sterilization, the BD test program was directly run and set as the control group. When the jacket pressure of the pressure steam sterilizer reached the set value before daily sterilization, the "no-load preheating" program was first run, followed by the BD test program, and set as the experimental group. In the two groups of the sterilization process, 13 sterilization PCDs with increasing difficulty of steam penetration, plus five kinds of chemical indicators and BD test package were placed. After sterilization, record the value of the most difficult PCD and the qualification of the BD test package.,Results,2,The average value of the most difficult PCD passed by the control group was 4.24, and the average value of the most difficult PCD passed by the experimental group was 8.32. The qualified rate of BD in the control group was 89%, and that in the experimental group was 100%; P<0.05, with statistical significance.,Conclusion,2,Preheating without load can improve the sterilization performance of pressure steam sterilizer before BD test every day.
