Objective To evaluate the clinical efficacy of integrated treatment ( sequential noninvasive following invasive mechanical ventilation, bronchoscope suction, combined inhalation) in patients with acute respiratory failure induced by chronic obstructive pulmonary disease ( COPD) . Methods 59 elderly patients with COPD and acute respiratory failure in ICU fromJuly 2006 to July 2009 were enrolled in the study. The patients were randomized into three groups, ie. a non-invasive mechanical ventilation group ( NIV group) , a sequential non-invasive following invasive mechanical ventilation group ( SV group) , a integrated treatment group ( IT group) . APACHEⅡ score, clinical pulmonary infection score ( CPIS) ,arterial blood gas analysis, respiratory rate ( RR) , heart rate ( HR) , and mean artery blood pressure ( MAP)
at 0 h, 3 h, 3 d, 12 d after treatment were recorded. Results With the extension of treatment time,APACHEⅡ score, CPIS score, RR, HR, PaCO2 , and white blood cells gradually reduced, while pH and PaO2 gradually increased in the three groups ( P lt;0. 05) . The differences in RR, HR, PaCO2 , and PaO2 at the time of 3 d and 12 d were significant between the three groups( P lt;0. 05) . The occurrence of pulmonary infection control ( PIC) window and ventilation associated pneumonia ( VAP) had no difference among the three groups( P gt;0. 05) . The duration of total mechanical ventilation, durations of ICU stay and hospital stay were shorter in SV group than those in NIV group( P lt;0. 05) . The duration of total mechanical ventilation,duration of invasive mechanical ventilation, durations of ICU stay and hospital stay were shorter in IT group than those in SV group( P lt;0. 05) . The incidence of VAP was higher in SV group than NIV group, but lower in IT group than SV group( P lt;0. 05) . Hospital mortality was lower in SV group than NIV group, and higher in IT group than SV group( P lt; 0. 05) . Conclusion In elderly COPD patients with acute respiratory failure, integrated treatment given early can reduce the duration of mechanical ventilation, the length of ICU and hospital stay, and decrease the morbidity of VAP and mortality.
