不同雾化吸入方式对哮喘婴幼儿血氧饱和度的影响

目的评价不同雾化吸入方式对哮喘婴幼儿血氧饱和度（SaO2）的影响。方法将62例哮喘婴幼儿随机分为空气压缩泵射流雾化组（n=22）与氧气射流雾化组（n=20）、超声雾化组（n=18）,均予布地奈德混悬液雾化吸入。在雾化吸入前、雾化吸入过程中及雾化吸入后10 min监测SaO2变化。结果雾化吸入过程中及雾化吸入后10 min氧气射流雾化组SaO2水平与空气压缩泵射流雾化组、超声雾化组均有显著性意义（Pa〈0.05）,雾化吸入过程中及雾化吸入后10 min空气压缩泵射流雾化组SaO2水平与超声雾化组比较均无统计学意义（Pa〉0.05）。结论不同雾化吸入方式对哮喘婴幼儿SaO2均有显著影响,氧气射流雾化更适合于婴幼儿哮喘患儿。

Influence of Different Nebulization Inhalation Methods on Blood Oxygen Degree of Saturation in Infants with Asthma

Objective To evaluate the effect of different nebulization inhalation methods on blood oxygen degree of saturation(SaO2) in infants with asthma.Methods Sixty-two infants with asthma were randomly assigned into 3 groups: air-high-frequency flow stonized inhalation group(n=22),oxygen-high-frequency flow stonized inhalationthe group(n=20) and ultrason jet nebulization group(n=18).Three groups all were gived budesonide suspl.SaO2 was monitored during nubulization.Results There were significant differences of SaO2 levels between oxygen-high-frequency flow stonized inhalationthe group and air-high-frequency flow stonized inhalationthe group,ultrason jet ne-bulization group after 10 min and during inhalation(Pa<0.05).There were no significant differences of SaO2 levels between air-high-frequency flow stonized inhalationthe group and ultrason jet nebulization group after 10 min and during inhalation(Pa<0.01).Conclusions There are significant effect of differen nebulization inhalation methods on SaO2 in infants with asthma.The oxygen-high-frequency flow stoni-zed inhalationthe more adequate for infants with asthma.
