The relative value of chest physiotherapy (including cough) and cough alone for the removal of excessive tracheobronchial secretions has been assessed in six patients with stable chronic obstructive lung disease. After labelling with inhaled radioactive tracer particles, clearance of secretions from selected central and peripheral lung regions was followed with a gamma camera linked to a computer. Cough alone and chest physiotherapy (including cough) were equally effective in the enhancement of central lung clearance. Physiotherapy but not cough along accelerated peripheral lung clearance (p less than 0.05). Sputum yield was greater during physiotherapy than during cough (p less than 0.05). These findings confirm the value of chest physiotherapy and high-light the limitation of cough in patients with excessive tracheobronchial secretion and impaired mucociliary clearance.
对6例稳定期慢性阻塞性肺疾病患者评估了胸部物理治疗(包括咳嗽)和单纯咳嗽在清除过多气管支气管分泌物方面的相对价值。在用吸入放射性示踪颗粒标记后,通过与计算机相连的γ相机跟踪选定的中央和外周肺区域分泌物的清除情况。单纯咳嗽和胸部物理治疗(包括咳嗽)在促进中央肺清除方面同样有效。物理治疗可加速外周肺清除,但咳嗽不能(p<0.05)。物理治疗期间的痰液生成量比咳嗽期间更多(p<0.05)。这些发现证实了胸部物理治疗的价值,并突出了咳嗽在气管支气管分泌物过多和黏液纤毛清除功能受损患者中的局限性。
