Observation of curative effects of noninvasive mechanical ventilation in the treatment of acute left heart failure / 中国现代医生

ABSTRACT

Objective To observe the curative effects of noninvasive mechanical ventilation in the treatment of acute left heart failure. Methods All 86 patients with acute left heart failure who were admitted to EICU in our hospital from January 2010 to June 2014 were selected. They were randomly assigned to observation group and control group, with 43 patients in each group; the observation group was given noninvasive ventilator on the basis of conventional medical treatment, and the control group was given conventional medical treatment and oxygen uptake. Heart rate, respiratory rate, ABG index and clinical effects between the two groups 4 hours after the treatment were compared. Results The differences of heart rate, respiratory rate, oxygen partial pressure and oxygen saturation before and after the treatment in the two groups were both statistically significant (P<0.01); curative effects in the observation group were signifi cantly better than those in the control group,and the difference was statistically significant(P<0.01); the difference of total effective rate in the two groups was statistically significant(P<0.05). Conclusion Noninvasive mechanical ventilation is able to rapidly improve the symptoms of acute left heart failure and correct hyoxemia, which has significant curative effect.
