Résumé
Objective To study the proper desiccation and the expiry date for humidifier after disinfection, and then decline the incidence rate of infection in hospital. Methods Divided 84 humidifiers into the A and B groups randomly after disinfection, there were 42 humidifiers in the each group. The natural desiccation was used in the A group, the oxygen desiccation was used in the B group. Monitored the humidifiers of the two groups respectively lasted 7 days, and then compare the datum between them. Results The expiry date of the humidifiers which have dried by natural desiccation was longer than that of humidifiers which have dried by oxygen desiccation. Conclusion We should set down the expiry date for humidifier according to the different desiccation and the different seasons.
Résumé
OBJECTIVE To discuss the effect of regular emptiness of humidification pot on ventilator associated pneumonia(VAP) in the patients with mechanical ventilation.METHODS Totally 240 mechanical ventilation patients were randomed to 2 groups,in an observation group the humidification pots were emptied per 24 hours and in a control group the fluid was added only when its water was lower limit and compared their incidence rate of VAP.RESULTS Ninety-six of 240 patients with mechanical ventilation had developed VAP and 238 pathogen strains were cultured.Altogether,the incidence of VAP in observation group was lower than those in control group significantly,?2=4.4,P
