肺心病气道阻塞41例临床分析

Clinical Study of Airway Obstruction in 41 Cases of Cor Pulmonale

肺心病气道阻塞，常因窒息或阻塞后低氧血症及高碳酸血症加重，酸碱失衡的复杂化病情急剧加重而死亡，病死率高达３４．１５％。因此，应熟悉气道阻塞的原因及临床特征，及时采取有效的预防和护理对策，加强气道管理，鼓励咳嗽、咯痰，定时刺激排痰，温湿化氧疗，用内径大的（０．５ｃｍ）鼻导管深吸痰，对降低肺心病气道阻塞的病死率，提高疗效有极为重要的作用。

Cor pulmonale (CP) accompanied with acute airway obstruction is fetal with extremely high mortality(34 . 15 % ) because of exacerbation of hypoxia and acid and base disequilibrium secondary to the airway obstruction orsuffication. Thus, awareness of the causes of obstruction and its clinical featurers, early diagnosis and effective nursingcares. such as intensive airway monitoring. encouraging cough and enhancing intermittent expectoration, warm and moist oxygenation,and bronchial suction of sputum with large tube ( 5mm) are very important for improving thetherapeutic efficacy and decreasing the death rate due to the obstruction o[ airway in patients with CP.
