脉导敏为一种静脉扩张药物。本文旨在检测两种不同剂量的脉导敏对肝和全身血液动力学以及奇静脉血流量的急剧作用。27例(男性15例,女性12例)临床确诊的肝硬化、门脉高压病人,平均年龄56±9岁。在测得基础值后,27例患者随机分为口服脉导敏2mg组(11例)、4mg组(8例)和口服安慰剂组(8例)。两组病人均在口服药物 Pulse-sensitive as a vein dilation of drugs. This article aims to examine the dramatic effects of pulse-induced sensitivity at two different doses on hepatic and systemic hemodynamics and venous hemodynamics. 27 cases (15 males and 12 females) with clinically diagnosed cirrhosis and portal hypertension, with a mean age of 56 ± 9 years. After baseline measurements, 27 patients were randomized to oral administration of 2 mg of aztreonam (11), 4 mg (8), and placebo (8). Both groups were taking oral medication
