已确认加压素能有助于制止门脉高压症并发食管静脉曲张破裂出血.使用后能减少肠系膜动脉的血流量.从而降低门静脉的血流量和压力.最初是用加压素1单位/分,快速静脉滴注,20分注入.不幸的是,用这种方法给药也使冠状动脉的血流量和心脏的排出量显著地降低,心绞痛或心肌梗塞可能是大剂量应用加压素的有害结果. Vasopressin has been identified can help prevent portal hypertension complicated with esophageal variceal bleeding after use can reduce the mesenteric artery blood flow and thus reduce the portal vein blood flow and pressure was initially vasopressin 1 unit / min , Rapid intravenous infusion, injection of 20. Unfortunately, administration of this method also significantly decreased coronary blood flow and cardiac output, angina or myocardial infarction may be harmful to large doses of vasopressin result.
