Effects of treatment with noninvasive positive pressure ventilation combined with aerosol inhalation budesonide on severe asthma / 中国综合临床

ABSTRACT

Objective To investigate the curative effect of noninvasive positive pressure ventilation combined with aerosol inhalation of budesonide on patients with severe asthma.Methods One hundred and twenty-one patients with severe asthma were randomly assigned to two groups.Both groups were treated with noninvasive positive pressure ventilation based on routine treatment.In addition,patients in the treatment group were given aerosol inhalation of 2 ml budesonide and 2 ml NS,two times each day,14 days for a course.Clinical symptoms improvement and arterial blood pressure changes of two groups before and after treatment were studied to compare the curative effect of the treatments in the two groups.Results There were no significant differences in pH,PaO2 and PaCO2 between the treatment and the control groups(P ＞ 0.05).After one course of treatment,the treatment group had significantly higher levels of pH(7.43 ± 0.04 vs.7.34 ± 0.02,t =3.423,P ＜ 0.05) and PaO2 ( [77.4 ± 16.7 ] mm Hg vs.[ 62.4 ± 16.5 ] mm Hg,t =3.414,P ＜ 0.05 ) and lower levels of PaCO2 ( [43.4 ±8.9] mm Hg vs.[50.9 ± 9.1 ] mm Hg,t =5.317,P ＜ 0.05 ) than the control group.There were significant differences in the total effective rate between the Budesonide group and the control group (96.7％ vs.88.3％,x2 =4.218,P ＜ 0.05 ).Conclusion Noninvasive positive pressure ventilation combined with aerosol inhalation of budesonide is a simple and effective strategy for patients with severe asthma.Thus it may be worthy to be widely used clinically.
