Objective:To explore the opportunity of noninvasive positive pressure ventilation sequential treatment for patients
with acute left heart failure combined with respiratory failure.Methods:Selected 120 cases of patients with acute left heart failure complicated
with respiratory failure in our hospital from June 2013 to August 2015 as the objects,after the illness were controled, all patients
were divided into three groups of A, B,C groups and with 40 patients in each group according to the time of pulled out the pipe, the pipe
ofA group was pulled out 30 min after spontaneous breathing, B group was after 2 h, while C group was after 24 h, and all patients were
treated with noninvasive positive pressure ventilation sequential, the blood gas analysis, the occurrence of ventilator associated pneumonia
and the success rate of off-line in the 3 groups were compared.Results:①Respiratory rate, heart rate, oxygen index, oxygen pressure,
oxygen partial pressure, carbon dioxide pressure and pH value in the 3 groups of patients were not significantly different (t1=1.402, t2=1.
338, t3=0.738, t4=1.201, t5=0.969, t6=0.857 P>0.0); ②Offline success rate of the A group was 7.50%, which was significantly lower than
77.50%of the B group and 82.50%of the C group, the differences were statistically significant (P< 0.05). The reintubation rate of the A
group was 92.50%, which was significantly higher than 22.50%of the B group and 17.50% of the C group, the differences were statistically
significant(P<0.05). The ventilator associated pneumonia incidence of the A group was 45.00%, which was significantly higher than
12.50%of the B group and 10.00%of the C group, the differences were statistically significant(P<0.05).Conclusion:Using non-invasive
positive pressure ventilation sequential treatment for patients with acute left heart failure combined with respiratory failure after extubation
of more than 2 h is able to significantly improve the success rate of weaning, reduce the reintubation rate,and the incidence of ventilator
associated pneumonia, which is worthy of clinical promotion. |
