经动脉导管灌注垂体后叶素治疗10条犬小肠出血的实验研究结果表明,垂体后叶素灌注治疗的效果与出血部位累及的血管大小及出血速率有关。还提示垂体后叶素对较大血管引起的出血灌注治疗无效,其引起血管的收缩作用主要在末梢小血管 The experimental study on the treatment of 10 dogs intestinal bleeding by intra-arterial catheter infusion of vasopressin showed that the effect of vasopressin perfusion was related to the vessel size and bleeding rate involved in the bleeding site. Vasopressin was also suggested that the bleeding caused by larger vessels perfusion therapy is ineffective, which causes vasoconstriction mainly in peripheral small vessels
