Abstract:
ObjectiveTo observe the discoloration of chemical indicator cards in different positions in pressure steam sterilization bags and stetilization effect.MethodsFrom January 2009 to January 2011,168 packages needing sterilization were divided into group A and group B randomiy with 84 packages in each.We put chemical indicator cards on different positions in the packages.Then discoloration of chemical indicator cards and the qualified rate of bacteriology detection were observed.ResultsThere were 9cases of uneven discoloration in group A,and the incidence rate was 10.71％,higher than group B.The unqualified rate of bacteriology detection in group A was 2.38％,higher than group B(1.19％),but the difference was not statistically significant.ConclusionsChemical indicator cards could reflect the effect of sterilization,but placing them in different positions can appear different results.The chemical indicator cards that placed between the two packing layer could provide powerful evidence for sterilization effects for clinicians,and avoid unnecessary economic waste in Sterilization and Supply Center,which is worthy of being widely used in Sterilization and Supply Center.
