煤工尘肺患者全肺灌洗治疗前后的肺功能变化特点

CHANGES IN PUMONARY FUNCTION OF COAL WORKER'S PNEUMOCONIOSIS AFTER LAVATION OF TWO LUNGS

本文对比观察22例煤工尘肺(Coal Workers Paeomoconiosis,CWP)患者大容量全肺灌洗前后的肺功能检测结果。结果表明,CWP 患者肺功能减退以 FEV1%降低最为明显,肺功能随 CWP 的病情加重而减退。大容量全肺灌洗后,Ⅰ期、Ⅱ期CWP 二组通气功能及小气道功能均有不同程度的改善。但灌洗后肺功能变化与CWP 的病程无关。吸烟量小、年限短的 CWP 患者较吸烟量大、年限长的尘肺患者全肺灌洗治疗效果更为明显。

Twenty-two CWP patient' spulmonary function were measured before and after lavetion of two lungs.The results of our study showed that the reduction of FEV_1 % was most significant,and pulmonary function decreased with an aggravation of the patient's condition.After lavation of two lungs, ventilatory function and small airway function test revealed improvement in varying degrees in CWP category Ⅰ and category Ⅱ,but the pulmonary function change after lavation of two lungs was not associated with the course of disease.The lavation therapy was more effective in CWP patients smoking with small doses and short time than in ones with large doses and long time.
