Abstract:

Objective

To investigate the effect of bi-level noninvasive positive pressure ventilation (BiPAP) on NT-proBNP and hs-CRP in the patients with type Ⅱ respiratory failure and heart failure.

Methods

Sixty patients with type Ⅱ respiratory failure and heart failure who were treated in the Emergency Department of our hospital from march 2019 to September 2019 were selected for this study. The patients were divided into a control group 31 cases and an experimental group 30 cases according to the random number table method. Both groups were treated with the conventional emergency treatment for type Ⅱ respiratory failure and heart failure at the time of admission. The control group received mask oxygen therapy on the basis of this, while the experimental group received BiPAP treatment. The differences between the general data, the arterial blood gas analysis and the cardiac function-related indicators, plasma NT-proBNP and hs-CRP, and the number of the patients with invasive ventilation during the treatment were compared before treatment (T1) and 24 h (T2) and 48 h (T3) after treatment. The patients were followed up for 12 months, and then the difference in mortality between the two groups was compared.

Results

There was no significant difference in general information between the two groups (P>0.05). The total effective rate of the experimental group was significantly higher than that of the control group (χ2=6.318 and P<0.05). At T2 and T3, the HR and BR were significantly lower and the SpO2 was significantly higher in the experimental group than the control group (P<0.05). At T2 and T3, the PCO2 was significantly lower and the PH, PaO2, LVEF and SV were significantly higher in the experimental group than the control group (P<0.05). At T2 and T3, the NT-proBNP and hs-CRP values in the experimental group were significantly lower than those of the control group (P<0.05). There was no significant difference in the number of patients with invasive mechanical respiration during the treatment between the two groups (χ2=2.074 and P=0.149). Log rank analysis showed that the risk of death in the experimental group was significantly lower than that of the control group (Log rank χ2=4.563 and P=0.034).

Conclusion

BiPAP can effectively improve the respiratory function and the cardiac function of the patients with type Ⅱ respiratory failure and heart failure. It can effectively treat the above diseases and improve the mortality within 1 year.
