Abstract:Objective To analyze the clinical study of ventilator in patients with acute severe heart failure in emergency department.METHODS Eighty-seven patients with acute severe heart failure who were admitted to the emergency department of our hospital from January 2014 to November 2015 were enrolled. The patients were divided into study group and control group according to the randomized controlled principle. 37 patients in the control group received routine treatment. In the treatment group, 50 patients were treated with ventilator on the basis of routine treatment.Statistical analysis of changes in related indicators (HR, RR, MBP, and PaO2), disappearance of clinical symptoms, time of weaning, and length of hospitalization, and observation of cardiac function grading and clinical effectiveness after treatment Tracheal intubation rate.RESULTS After treatment, the HR, RR and MBP of the study group were significantly lower than the control group, and the PaO2 level was significantly higher than the control group (P＜0.05).At the same time, the study group's lung voice, cyanosis and disturbance of consciousness symptoms and the time of weaning and hospital stay were shorter than the control group (P＜0.05).After treatment, the improvement of cardiac function in the study group was significantly better than that of the control group. The tracheal intubation rate of the study group was lower than that of the control group, and the difference was statistically significant (P＜0.05). The total effective rate of the study group was higher than that of the control group (P＜0.05).Conclusion For patients with acute severe heart failure in the emergency department, early combined with ventilator treatment on the basis of routine treatment can effectively relieve symptoms, improve cardiac function, and reduce tracheal intubation for clinical reference.
