咳嗽是呼吸道固有的一种保护性反射,据报道该反射的抑制或消失,可以导致吸入性肺炎。为判定咳嗽反射与吸入性肺炎之间的关系,作者就吸入性肺炎患者对枸橼酸和物理刺激的反应进行了对照研究。5例吸入性肺炎患者,平均年龄80负,胸部 X线显示在相应的肺段吸气时至少有两次肺部感染的证据。对照组10例,平均年龄78岁,均有脑动脉 Cough is a protective reflex intrinsic to the respiratory tract, and the suppression or loss of this reflex is reported to cause aspiration pneumonia. To determine the relationship between cough reflexes and aspiration pneumonia, the authors conducted a controlled study of citrate and physical stimuli in patients with aspiration pneumonia. Five patients with aspiration pneumonia, mean age 80 years old, had chest radiographs showing evidence of pulmonary infection at least twice during inspiration in the corresponding segment. Control group, 10 patients, mean age 78 years, with cerebral artery
