Effect analysis on airway management based on different grades in mechanically ventilated patients with severe pneumonia

Objective To evaluate the effect of airway management based on different grades in mechanical ventilated patients with severe pneumonia.Methods A prospective cohort controlled study was applied to the trail.A total of 76 severe pneumonia patients were randomly divided into two groups.The patients in control group(36 cases) received conventional chest physiotherapy every 2 hours.The patients in study group(40 cases) were taken into the chest physiotherapy program in different frequency according to airway grading assessment scores.The tidal volume(VT),respiratory rate,oxygenation index(PaO2/FiO2 ratio),patient's overall severity by acute physiology and chronic health evaluation(APACHE) II score,duration of stay in intensive care unit(ICU),duration of ventilator support,andcomplications were assessed and compared between the two groups.Results Compared with the control group,the VT,respiratory rate,PaO2/FiO2 ratio were better(all P0.001),andAPACHEⅡscore was lower on the 7th d after mechanical ventilation in the study group(P0.05).In addition,the duration of ventilator support was shorter in the study group(P0.001).Conclusion Airway management based on different grades could reduce the sideeffects of chest physiotherapy,improve the respiratory function and shorten the duration of ventilator support in patients with severe pneumonia.
