  • Correlation Analysis between Compliance of Clinical Respiratory Bundle and Duration of Mechanical Ventilation

    ObjectiveTo investigate the correlation between compliance of clinical respiratory bundle and duration of mechanical ventilation. MethodsThe data of patients who admitted to intensive care unit (ICU)of Cancer Hospital Chinese Academy of Medical Sciences between June 2013 and December 2014 were retrospectively reviewed and analyzed.The patients with respiratory insufficiency who ventilated more than 48 hours were included into the study. ResultsFifty-five patients were enrolled into the final analysis.There were 43 males and 12 females with a mean age of 63.47±12.49 years.The mean sequential organ failure assessment (SOFA)score was 2.8±2.2,and the mean simplified acute physiology score 3 (SAPS3)was 51±14 on ICU admission.The mean duration of mechanical ventilation of all 55 patients was 7.3±5.5 days.The compliance of low tidal volume strategy was 23.6%(13/55).No significant difference was found on duration of mechanical ventilation between the patients who was compliant with low tidal volume strategy and the patients who was not compliant (7.31±7.02 days vs. 7.31±5.07 day,P=0.444).A negative correlation between compliance of protocolized sedation strategy and duration of mechanical ventilation was found by Bivariate spearman correlation analysis (r2=0.312,P<0.001).A negative correlation between compliance of spontaneous awakening trial strategy and duration of mechanical ventilation (r2=0.337,P<0.001)and a negative correlation between compliance of spontaneous breathing trial strategy and duration of mechanical ventilation (r2=0.280,P<0.001)were also found by Bivariate spearman correlation analysis.Multiple linear regression analysis showed that only spontaneous awakening trial strategy was correlated with duration of mechanical ventilation(B=-0.623,P<0.001). ConclusionThe more compliance with clinical respiratory bundle,especially with spontaneous awakening trial strategy,the shorter of duration of mechanical ventilation.The effect of low tidal volume strategy on the duration of mechanical ventilation needs further studies.
