多功能呼气阀锻炼在学龄期支气管扩张症儿童气道廓清中的应用

Application of multifunctional breath valve exercise in airway clearance of school⁃aged children with bronchiectasis

目的:探讨多功能呼气阀锻炼在学龄期支气管扩张症儿童的临床应用效果。方法:选取广州医科大学附属第一医院儿科住院的103例学龄期支气管扩张症儿童为研究对象。采用类实验研究设计,将2019年8月至2021年12月收治的患儿作为对照组,总计45例,给予常规治疗护理方案。将2022年1月至2023年10月收治的患儿为观察组,纳入58例,除予常规护理治疗外,给予多功能呼气阀锻炼。比较两组患儿干预前后24 h咳痰量、咳嗽症状评分、住院天数。结果:多功能呼吸阀干预后,对照组和观察组患儿24 h咳痰量分别为(25.44±4.12)ml、(29.50±4.54)ml,两组间的差异在统计学上有显著(P<0.05)。干预后对照组患儿日间咳嗽积分、夜间咳嗽积分、咳嗽症状总积分分别为(1.20±0.62)分、(0.75±0.48)分、(1.95±0.87)分,观察组患儿日间咳嗽积分、夜间咳嗽积分、咳嗽症状总积分分别(0.87±0.62)分、(0.34±0.47)分、(1.22±0.85)分。相比于对照组,观察组患儿的咳嗽症状缓解较明显,两组间的咳嗽积分差异具有统计学上的显著性(P<0.05)。观察组患儿平均住院天数为(9.00±3.35)d,较对照组患儿(10.37±3.11)短(P<0.05)。结论:多功能呼气阀锻炼可有效促进学龄期支气管扩张症儿童呼吸道分泌物清除,改善患儿的咳嗽症状及痰液情况,改善患儿病情。

Objective:To investigate the effect of multifunctional breath valve exercise in airway clearance of school⁃aged children with bronchiectasis.Methods:103 school⁃age children with bronchiectasis who were hospitalized in the department of Pediatrics were selected.According to the quasi⁃experimental study,the research subjects were divided into control group and experimental group.From August 2019 to December 2021,45 children were admitted as the control group,they recieved conventional therapy.58 children admitted from January 2022 to October 2023 were the observation group,they were treated with multifunction breath valve exercise in addition to conventional therapy.The 24 h sputum volume,cough symptom score and length of hospital stay were compared between two groups.Results:After intervention the 24⁃hour sputum volume of the control group and the observation group was(25.44±4.12)ml and(29.50±4.54)ml,and the difference between the two groups was significant(P<0.05).The daytime cough score,night cough score and total cough symptom score of the control group at discharge were(1.20±0.62),(0.75±0.48)and(1.95±0.87)points.In the observation group,the daytime cough score,the nighttime cough score and the total cough symptom score were(0.87±0.62)points,(0.34±0.47)points and(1.22±0.85)points.The cough relief in the observation group was significantly higher than that in the control group(P<0.05).The length of hospitalization in the observation group was(9.00±3.35)days,which was shorter than that in the control group(10.37±3.11)(P<0.05).Conclusions:Multifunction breath valve exercise can effectively promote the removal of respiratory secretions in school⁃age children with bronchiectasis,improve the symptoms of cough and sputum,and improve the condition of children.
