初级医疗机构中哮喘患者感知的哮喘控制程度与胸腹异步的相关性
2012/11/19
摘要
目的:胸腹异步(TAA;胸部与腹部起伏不一致)会影响健康相关变量。本试验研究TAA程度与健康相关变量的关系,特别是感知的哮喘控制和生活质量。
方法:对43名哮喘患者和43名年龄、性别匹配的对照者,记录4 h的非卧床呼吸数据。采用相位关系(Ph Rel Total,胸廓(RC)和膈肌运动相对胸腔内体积反向影响的时间比例)对TAA进行定量。受试者完成迷你哮喘生活质量问卷调查(AQLQ)、哮喘控制问卷调查(ACQ)、奈梅亨问卷调查(NQ)、医院焦虑和抑郁量表(HADS)、斯皮尔伯格状态-特质焦虑量表(STAI)和简表36-问卷调查的一般健康感知(GHP)量表。同时进行二氧化碳描记、屏气时间(BHT)检测和标准肺活量检测。
结果:哮喘患者的异步时间显著长于健康对照(Ph Rel Total=14%[IQR:8.5-20.7%] vs10.4% [IQR 7.1-14.5%],P=0.012)。对于哮喘患者,Ph Rel Total与较差的ACQ评分相关性较弱(r = 0.33, p = 0.03);对于健康对照,Ph Rel Total与GHP相关(r = 0.319, p = 0.037)。事后探索性分析显示,女性哮喘患者总Ph Rel与AQLQ呈中等程度相关(r = -0.56,P=0.003)。
结论:TAA可能与感知的哮喘控制下降相关。对于健康者,异步与总体健康状态感知较低相关。有必要研究TAA下降是否能改善这些健康相关变量。

Abstract
OBJECTIVE:Thoraco-abdominal asynchrony (TAA), the discordant movement of the abdomen and thorax, may impact upon health-related variables. Here, we investigated the extent to which TAA is associated with health-related variables, particularly perceived asthma control and quality of life.
METHODS:Ambulatory respiratory data from 43 patients diagnosed with asthma and 43 healthy age and sex-matched controls were recorded over 4 hours. Phase relation (Ph Rel Total), the percentage of time that the effects of rib cage (RC) and diaphragmatic movement result in opposite effects on intra-thoracic volume, quantified TAA. Subjects completed the Mini Asthma Quality of Life Questionnaire (AQLQ), Asthma Control Questionnaire (ACQ), Nijmegen questionnaire (NQ), Hospital Anxiety and Depression Scale (HADS), Spielberger State-Trait Anxiety Inventory (STAI), and General Health Perception (GHP) subscale of the short form 36 questionnaire’. Capnography profiling, breath-hold time (BHT), and standard spirometry were performed.
RESULTS:The time in asynchrony was significantly greater in the asthma than in the healthy control group (Ph Rel Total = 14% (interquartile range (IQR) 8.5-20.7%) versus 10.4% (IQR 7.1-14.5%), p = .012). In patients with asthma, Ph Rel Total was weakly associated with poorer ACQ scores (r = 0.33, p = .03), and in the healthy control group with GHP (r = 0.319, p = .037). Post-hoc exploratory analysis revealed a moderate relationship in the female asthma subgroup between Ph Rel Total and AQLQ (r = -0.56, p = .003).
CONCLUSIONS:TAA may be associated with decreased perceived asthma control. In healthy individuals, asynchrony may be associated with low perception of general health. Further studies are required to investigate if the reduction of TAA improves these health-related variables.
