Abstract:
OBJECTIVE To find out the situation of bacteriological contamination of oxygen humidified fluid in the hyperbaric oxygen chamber in Nanfang Hospital and take appropriate measures accordingly to provide valuable reference for avoiding possibly resulting hospital infection.METHODS Before and after beginning periodically changing oxygen humidified fluid,the humidifying fluid in the oxygen humidifiers of three hyperbaric oxygen chambers in this hospital was sampled once a season.The samples were analyzed with bacteria counting and identification.RESULTS The average amount of bacteria in the samples before and after changing oxygen humidified fluid was(7.9 ? 104) CFU/ml and(2.8 ? 103) CFU/ml,respectively.Identified bacteria were conditioned pathogens,including Chryseobacterium,Acinetobacter baumannii,Escherichia coli,Pseudomonas aeruginosa,Candida albicans,etc.Among them the frequency of Chryseobacterium was the highest.The results had no correlation with the changing of seasons.CONCLUSIONS Hyperbaric oxygen chamber should be disinfected periodically,the humidified fluid should be changed every day,and the amount of bacteria in it should lower than 103 CFU/ml.
