异物呛入孩子气管的症状

来源:华人健康网 | 发布时间:2010-07-26 20:14:42 | www.chinesejk.com

  (1)喉部异物异物被呛入喉部后,常常出现剧烈的咳嗽、气闷、呼吸困难、声哑和面色发紫等症状。喉部阻塞严重的病例,由于呼吸骤然困难,缺氧严重,可在数分钟内窒息致死。病情较轻的病人,由于异物刺激,喉部和声门逐渐出现水肿,也可使喉梗阻加重,出现明显的呼吸困难。

  (2)气管异物初发时的症状往往和喉部异物相似,接着可进入比较平静的间歇期,以后异物可能引起阵发性刺激性咳嗽、呼吸困难和面色发紫等现象。此外,呼吸时可闻气流通过异物处而发出的喘鸣声,用手扪及气管上部有异物撞击的感觉。如异物阻塞严重,可立即窒息而引起死亡。

  (3)支气管异物除有气管异物的症状外,可根据阻塞支气管程度的不同而出现肺气肿或肺不张。植物性异物如花生等,可使气管粘膜发炎而出现高热。有时因咳嗽不止,肺部炎症不能控制而进行胸部X线摄片,才明确诊断。
