The paper is concerned with the results of echocardiography, Doppler cardiography, radionuclide investigation and direct pressure measurement in the peripheral vein in 22 patients with chronic obstructive bronchitis and 7 persons with normal bronchial permeability. It was shown that the diameter of the peripheral veins, the pressure and rate of the blood flow in them and liver enlargement in patients with chronic obstructive bronchitis depended, to a large extent, on respiratory fluctuations of intrathoracic pressure. A conclusion was made that peripheral vein swelling and liver enlargement which were considered to be common symptoms of the development of right ventricular insufficiency, resulted from an increase in intrathoracic pressure during exhalation making difficult blood venous return to the heart in patients with dramatic disorders of bronchial permeability.
本文关注的是22例慢性阻塞性支气管炎患者及7例支气管通透性正常者的超声心动图、多普勒心动图、放射性核素检查结果以及外周静脉直接压力测量结果。结果表明,慢性阻塞性支气管炎患者外周静脉直径、静脉内压力和血流速度以及肝脏肿大在很大程度上取决于胸内压的呼吸波动。得出的结论是,被认为是右心室功能不全发展常见症状的外周静脉肿胀和肝脏肿大,是由于呼气时胸内压升高,导致支气管通透性严重紊乱的患者静脉血回流至心脏困难所致。
