问题 四岁男童,吃花生米时突发气促,吸气困难,诊断为气管异物,查体可见
选项 A.呼气时,胸骨上窝、锁骨上窝、肋间隙向内凹陷 B.吸气时,胸骨上窝、锁骨上窝、腹部向内凹陷 C.吸气时,胸骨上窝、肋间隙、腹部向内凹陷 D.呼气时,胸骨上窝、锁骨上窝、腹部向内凹陷 E.吸气时,胸骨上窝、锁骨上窝、肋间隙向内凹陷
答案 E
解析 吸气性呼吸困难,由于喉、气管、大支气管的炎症水肿、肿瘤或异物等引起狭窄或梗阻所致。其特点是吸气显著困难,高度狭窄时呼吸肌极度紧张,胸骨上窝、锁骨上窝、肋间隙在吸气时明显下陷(称为"三凹征"),可伴有干咳及高调的吸气性哮鸣音。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
