改良“三步排痰”技术在婴幼儿肺炎中的应用

Application of Improved "Three Step Phlegm Discharge" Approach in Pneumonia Infants

目的观察改良"三步排痰"技术在婴幼儿肺炎中的临床使用效果。方法将我科810例住院的肺炎患儿随机分为两组。对照组(400例)采用传统的排痰技术,试验组(410例)采用改良"三步排痰"技术,即采用雾化吸入、排痰机振动、刺激吸痰来辅助婴幼儿排痰。对两组治疗前后呼吸功能指标及排痰量、肺部湿性啰音消退时间进行比较。结果治疗后两组动脉血氧饱和度、氧分压、心率及呼吸频率均优于治疗前,且治疗后上述各项指标比较试验组明显优于对照组,差异均有统计学意义(P<0.05)。治疗后试验组排痰量和肺部湿性啰音消退时间分别为每次(22.04±3.12)ml和(4.25±1.03)d较对照组每次(20.18±1.21)ml和(5.27±1.78)d明显好转,差异有统计学意义(P<0.05)。结论采用改良"三步排痰"技术辅助排痰能有效清除婴幼儿肺炎患儿呼吸道分泌物,提高排痰效果。

Objective To investigate the clinical effect of improved 'three-step-phlegm-discharge' approach in pneumonia infants. Methods 810 hospitalized pneumonia infants were randomly divided into two groups: control group(n=400) received traditional phlegm discharge therapy,while the experiment group(n=410) received 'three step phlegm discharge' therapy to help the patients to discharge phlegm,including atomization inhalation,vibration of phlegm discharge machines and sputum aspiration by stimulation.The indicators of lung function,phlegm discharge volume,and regression time of lung rales in both groups were compared before and after treatment.Results SpO2,PaO2,heart rate and breathing rate in both groups were better than that before treatment(P<0.05),and all the indicators in experiment group were better than those in the control group(P<0.05).When compared with those in control group,the phlegm discharge volume in experiment group was larger(22.04±3.12)ml vs.(20.18±1.21)ml,and regression time of lung rales was shorter(4.25±1.03)d vs.(5.27±1.78)d.Conclusion The improved 'three step phlegm discharge' technology can clean respiratory tract secretion effectively in pneumonia infants,thus enhancing the effect of phlegm discharge significantly.
