超声雾化吸入液中生理盐水浓度对肺炎患儿治疗效果的影响

Effect of the Concentration of Normal Saline in Ultrasonic Atomization Inhalation on Therapeutic Efficacy of Children with Pneumonia

目的探讨超声雾化吸入液中生理盐水浓度对肺炎患儿治疗效果的影响。方法选取本院2014年6月～2015年6月收治的90例肺炎患儿作为研究对象,随机分为A组(n=30)、B组(n=30)和C组(n=30),所有患儿均予以肺炎常规治疗,此外,A组患儿雾化吸入4%生理盐水,B组患儿雾化吸入3%生理盐水,C组患儿雾化吸入0. 9%生理盐水。分别对3组患儿的痰标本合格率、阳性率;咳嗽、气促症状缓解时间,啰音消失时间,以及住院时间进行比较。结果 A组和B组患儿的标本合格率和阳性率明显高于C组(P <0. 05),A组和B组患儿的标本合格率和阳性率,差异无统计学意义(P均> 0. 05); B组患儿的咳嗽、咳痰缓解时间及啰音消失时间,住院时间均明显低于A组和C组(P <0. 05); A组患儿的咳嗽、咳痰缓解时间及啰音消失时间,住院时间均明显低于C组,差异有统计学意义(P <0. 05)。结论 3%生理盐水应用于超声雾化吸入可以提高痰液标本的合格率与阳性率,且能够更好的减少症状缓解和体征消失的时间,缩短住院时间。

Objective To explore the effect of the concentration of normal saline in ultrasonic atomization inhalation on therapeutic efficacy of children with pneumonia. Methods 90 children with pneumonia from June 2014 to June 2015 was randomly divided into three groups,Group A(n=30),Group B(n=30) and Group C(n=30).All patients accepted conventional therapy of pneumonia.In addition,group A was inhaled with 4% saline,group B was inhaled with 3% saline,and group C was inhaled with 0.9% saline.The sputum specimens,positive rate,cough,annelation remission time,rale disappearance time,and length of hospital stay were compared among the three groups. Results The specimen pass rate and positive rate of patients in Group A and Group B were obviously higher than Group C(P<0.05).But there was no difference between the Group A and Group B.The cough,annelation remission time,rale disappearance time,and length of hospital stay of Group B were obviously lower than Group A and Group C (P<0.05).The cough,annelation remission time,rale disappearance time,and length of hospital stay of Group A were obviously lower than Group C (P<0.05). Conclusion 3% of normal saline in ultrasonic atomization inhalation could improve specimen pass rate and positive rate.Meanwhile,it could reduce remission time,rale disappearance time,and shorten length of hospital stay.
