Abstract

The changes in the regional micro-hemodynamics in patients with obliterative diseases of the arteries of the lower extremities under the influence of intravenous injection of 0.3-0.4 mg of norepinephrine at a rate of 0.04-0.05 mkg/(kg.min) were established. After 6-7 injections of norepinephrine, the volume-pulse blood supply in the toes increased significantly, the local peripheral resistance of the vessels decreased. Simultaneously, the blood content of epinephrine and norepinephrine decreased.

摘要

研究了下肢动脉闭塞性疾病患者在以0.04 - 0.05微克/(千克·分钟)的速率静脉注射0.3 - 0.4毫克去甲肾上腺素影响下局部微血流动力学的变化。在注射6 - 7次去甲肾上腺素后,脚趾的容积脉搏供血显著增加,血管局部外周阻力降低。同时,肾上腺素和去甲肾上腺素的血含量下降。
