ABSTRACT
OBJECTIVE To explore disinfection effect of ventilator circuits and monitor the best one from two methods for sampling bacterial culture of pre-and post-mechanical physical disinfection ventilator circuit as well as different culture media.METHODS Pre-and post-disinfection ventilator circuits were sampled and cultured by the direct smudge method and the dilution method respectively which simultaneously the ordinary nutrient agar and the blood cultures used.RESULTS Bacterical positive rate of the direct smudge method was significantly higher than that of the dilution method in pre-and post-disinfection ventilator circuits(P0.05).CONCLUSIONS The direct smudge method is superior to the dilution method in monitoring the disinfection effect of ventilator circuit,it can effectively reduce the false negative rate and make the disinfection effect examination to be more accurate.
