Abstract:
Objective:To study on the best replacement time of breathing humidification pot liquid in mechanical ventilation.Methods:33 mechanical ventilation patients were randomly divided into observation group and control group,in the observation group the humidification pot liquid were replaced 7 days,while in a control group were replaced every day,all liquid samples were cultured for bacteria.Results:119 samples collected in observation group have 3 cases with positive bacterial growth(2.5%),while 112 samples collected in control group have 15 cases with positive bacterial growth(13.4%).Conclusion:Replace humidification pot liquid of breathing machine everyday may cause bacterial pollution more easily than they were replaced in 7 days interval.
