不同雾化吸入方式对急性阻塞性肺疾病患儿血氧饱和度的影响及对策

目的 探讨不同雾化吸入方法对急性阻塞性帅疾病（AOPD）患儿血氧饱和度（SaO2）的影响及护理对策。方法 选择患AOPD的住院婴幼儿240例，将其分为重症组和轻症组．每组再分为氧气雾化组和超声雾化组．并在雾化治疗时监测SaO2的变化。结果 氧气雾化时SaO2明显升高（P〈0．01），雾化结束后的SaO2与雾化前比较却无显著的变化；但超声雾化吸入组的直症组，其SaO2显著低下（P〈0．01）。结论 不同雾化吸入方式对AOPD患儿的SaO2有显著影响，氧气雾化吸入比超声雾化吸入更适于AOPD的患儿；对雾化吸入后SaO2明显下降的患儿，改变护理措施往往能达到提升SaO2的效果。

Countermeasure and Effect of Different Nebulization Inhalation Methods on SaO2 in Infant with AOPD

Objective To explore the effects of different nebulization inhalation methods on oxygen saturation(SaO_2) of infants with acute obstructive pulmonary diseases (AOPD) and to develop the nursing countermeasures during the inhalation.Methods 240 infants hospitalized with AOPD were enrolled in this study.The infants were divided into 2 groups:severe group and mild group.Each group was subdivided into OJN(oxygen jet nebulization)group and UN (ultrasonic nebulization) group.The SaO_2 was monitored during the nebulization inhalation.Results The levels of SaO_2 in OJN groups improved significantly during inhalation(P<0.01).However, there were no significant differences of the SaO_2 levels after and before the OJN inhalation.The SaO_2 level in the severe group of UN group was significantly low (P<0.01).Conclusion Different methods of nebulization inhalation have significant effects on the SaO_2 in infants with AOPD.Compared with UN,OJN is more adequate for children suffering from AOPD.As for those SaO_2 lowered obviously after inhalation,the SaO_2 will increase by adjusting nursing interventions.
