Cardiac output and regional perfusion was measured in neonatal piglets using radionuclide labeled microspheres. Measurements made at normal core body temperature (38-39.5 degrees C) were compared to those obtained after a 4-5 degrees C reduction in temperature. There is a significant reduction in cardiac output and in the myocardial, renal, pancreatic, and adrenal blood flow. The separated layers of the gastrointestinal tract wall are subject to varying decreases in blood flow. The mucosa of the distal small intestine demonstrated the most significant decreases in blood flow during mild hypothermia.
使用放射性核素标记的微球测量新生仔猪的心输出量和局部灌注。将正常核心体温（38 - 39.5摄氏度）下的测量结果与体温降低4 - 5摄氏度后的测量结果进行比较。心输出量以及心肌、肾脏、胰腺和肾上腺的血流量均显著降低。胃肠道壁的不同层次血流量减少程度各异。在轻度低温期间，远端小肠黏膜的血流量减少最为显著。
