知信行模式在重症支气管扩张合并肺部感染老年病人中的应用及对自我管理能力的影响

Application and the effect of knowledge-belief-practice model on self-management ability in patients with severe bronchiectasis complicated with pulmonary infection

目的探讨知信行模式在老年重症支气管扩张合并肺部感染病人雾化吸入治疗中的应用及对自我管理能力的影响。方法选择2017~2019年94例老年重症支气管扩张合并肺部感染病人,随机分为对照组和观察组,每组47例。2组均给予吸入乙酰半胱氨酸溶液雾化治疗,对照组给予常规护理干预,观察组在对照组基础上进行知信行模式护理干预。比较2组病人干预前后肺功能、动脉血气指标及自我管理能力的变化。结果干预后观察组病人的肺活量、呼气流速、呼气容积均优于对照组(P<0.05);观察组干预后pH值、PaO2以及血氧饱和度(SaO2)均高于对照组(P<0.05),PaCO2低于对照组(P<0.05);干预后4周观察组病人的自我饮食管理、药物管理、情绪管理、健康知识水平和自我保健能力评分均高于对照组(P<0.05)。结论将知信行模式用于老年重症支气管扩张合并肺部感染病人雾化吸入治疗中效果较好,可有效改善病人肺功能以及动脉血气指标,提高病人自我管理能力,值得推广应用。

Objective To explore the application of the knowledge-belief-practice model on atomization inhalation therapy in the patients with severe bronchiectasis complicated with pulmonary infection and the effect on self-managment ability.Methods From 2017 to 2019,ninety-four patients with severe bronchiectasis and pulmonary infection were selected and divided into control group and observation group,with 47 cases in each group.Both groups were treated with aerosol inhalation of acetylcysteine solution.The control group was given routine nursing intervention,and the observation group was given the knowledge-belief-practice mode intervention on the basis of the control group.Lung function,arterial blood gas index,and self-management ability were compared between the two groups before and after intervention.Results After the intervention,the vital capacity,expiratory flow rate,and expiratory volume in the observation group were higher than those in the control group(P<0.05).The pH,arterial oxygen pressure(PaO2),and arterial oxygen saturation(SaO2)in the observation group were higher than those in the control group(P<0.05),and the arterial blood carbon dioxide partial pressure(PaCO2)was lower than that in the control group(P<0.05).The self-dietary management,drug management,emotional management,health knowledge level and self-care ability score in the observation group were higher than those in the control group(P<0.05).Conclusions The use of the knowledge-belief-practice model is beneficial in the treatment of the patients with severe bronchiectasis and pulmonary infection.It can effectively improve the patients'pulmonary function index,the arterial blood gas index,and the patient's self-management ability,which is worth popularizing and applying.
