OBJECTIVE To investigate the application of risk management in the practice of the sterilization supply department.METHODS Through the risk management theory to identify and evaluate the latent risk factor and achieve the purpose of preventing and controlling.To improve the awareness and ability of risk guarding among nurses by strengthening professional training and establish and perfect the regulations,we insisted on "zero fault" management idea and adopted irregular spot-checking and quality overruled system.We also bought the results into bonus-penalty system and continue for the quality improvement.RESULTS It strengthened the risk and quality cognition and the responsibility of the nurses and reduced the occurrences of the small defects and defaults.CONCLUSIONS The risk and quality management is binding with each other.Through the applications of risk management the most high quality sterilized goods are offered to our clinical practice due to the decreasing in risk factors.

Disinfection of Ventilator Circuits:A Comparison with Three Methods / 中华医院感染学杂志

OBJECTIVE To compare the effect with the three methods to disinfect the ventilator circuits.(METHODS) To disinfect the ventilator circuits,three methods were used:A,soaking with chlorine compoud(disinfectant);B:soaking with 0.5% peracetic acid;C,sterilizing with ethylene oxide.Samples were taken to(bacteria) culture before and after disifection in every three methods.Biological supervision and the amount of colony were also taken at the same time.RESULTS The results of bacteria culture pre-disinfection were all positive.The amount of bacteria of ventilator circuits was between 70 000-120 000CFU/cm~2.The eligible rate of biological(supervision) in method C was 100% and its positive rate of bacteria culture was 0%.The eligible rate of biological supervision in method A was 86.25% and its positive rate of bacteria culture was 16.25%.The eligible rate of(biological) supervision in method B was 90% and its positive rate of bacteria culture was 13.78%.It was significant when method C was compared with methods A and B and the value P was less than 0.01.CONCLUSIONS It is(serious) about the pollution in ventilator circuits.The soaking methods are apt to be effected by the factors of(environment) and manual operation.Therefore it could be(ineligible) and being polluted after disinfection.The method of sterilization is the best for disinfection.
