Abstract:
Objective To compare the detection results by bacteria pathogenic rate of ventilatorassociated pneumonia (VAP) pipeline and ventilator patients with mechanical ventilation,to investigate whether need to replace the ventilator weaning patients underwent another test of pipeline during mechanical ventilation.Methods This study selected using the ventilation mechanical ventilation for more than 48 hours,try (48 ± 4) hours required to mechanical ventilation in 69 patients.They were divided into two groups according to admission time,group A was in need of replacement ventilation pipeline of new again during mechanical ventilation,group B used the original pipeline.In offline,try again during mechanical ventilation after mechanical ventilation,once daily for 4 days to collect ventilator pipe air outlet samples for bacterial culture counts were observed,while offline,use again after 2 hours,12 hours of ventilator,24 hours,2 days,3 days,4 days of body temperature,white blood cell count,neutrophil classification and other indicators.The incidence of VAP was compared between two groups.Results The temperature,white blood cell count,neutrophil classification were (38.5 ± 1.6)℃,(11.8 ± 3.5)×109/L,0.85±0.16 in group A,while (38.4 ± 2.0) ℃,(12.1 ± 3.7)×109/L,0.84 ± 0.20 in group B,and there were no significant differences between two groups,P＞0.05.The incidence of VAP was 37.1％(13/35) and 35.3％(12/34) in group A and group B,and there was no significant difference,P＞ 0.05.Conclusion There is no necessary for trial offline patients without respiratory infection to change the ventilator pipe when to re-ventilate during the 7 days using period of the ventilator pile.
