Pathogens Isolated from Breathing Circuit in Mechanical Ventilation Patients: Analysis and Nursing Intervention / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the breathing circuit bacteria and the lower respiratory airway bacteria(LRAB) isolated from mechanical ventilation patient. METHODS A total of 48 strains of the breathing circuit and 87 strains of LRAB from mechanical ventilation patients were analyzed. RESULTS The main organism in the breathing circuit were Pseudomonas aeruginosa(31.2%),and Stenotrophomonas maltophilia(27.2%).The main organisms in LRAB were P.aeruginosa(37.9%),Klebsiella pneumoniae(17.3%) and Candida albicans(13.7%).The pathogens of the breathing circuit were 73.3 % similar with those of LRAB. CONCLUSIONS To control infection effectively,effective sterilizing measures must be carried out,especially attention to sterilizing and managements of the breathing circuit.
