Radioactive microspheres, labeled withe ytterbium (169Yb), strontium (85Sr) and cerium (141Ce) were used in an investigation of the cardiovascular response to superficial thiopental anesthesia. The course was followed for 90 min and measurements were carried out 30, 60 and 90 min, respectively. Between 30 and 60 min of anesthesia there was a slight decrease in cardiac output and left ventricular work. The blood flow was reduced to the lungs, kidneys and the liver. Between 60 and 90 min there were, except for the coeliac artery and total liver, no further changes, which indicated a circulatory steady state.
用标记有镱（169Yb）、锶（85Sr）和铈（141Ce）的放射性微球来研究心血管系统对硫喷妥钠表面麻醉的反应。观察过程持续90分钟，分别在30、60和90分钟时进行测量。麻醉30至60分钟之间，心输出量和左心室作功略有下降。肺、肾和肝脏的血流量减少。60至90分钟之间，除腹腔动脉和整个肝脏外，没有进一步变化，这表明循环处于稳定状态。
