TY -的T1 -气管软化和bronchomalacia我n children: response to the ERS statement JF - European Respiratory Journal JO - Eur Respir J DO - 10.1183/13993003.02098-2019 VL - 54 IS - 6 SP - 1902098 AU - Crowley, Suzanne AU - Carlsen, Kai-Håkon Y1 - 2019/12/01 UR - //www.qdcxjkg.com/content/54/6/1902098.abstract N2 - We welcome the timely publication of the European Respiratory Society statement on tracheomalacia and bronchomalacia (TBM) in children [1], but are concerned that the definition of malacia used in the statement may contribute to underdiagnosis in those older children with milder degrees of malacia whose main symptom is exercise limitation [2]. Malacia in the statement is defined as an “arbitrary >50% expiratory reduction in the cross-sectional luminal area during quiet respiration” diagnosed with the use of multidetector computed tomography (MDCT); the authors cite seven references in support of their definition.Dynamic expiratory manoeuvres should be used to diagnose mild airway malacia http://bit.ly/2NBJ3Mn ER -
