MEASUREMENT OF THE VISCERAL BLOOD VOLUME IN DOGS
1 Department of Surgery, University of Edinburgh
1. By the exclusion technique using the radioactive isotope P32 as a tracer substance in dogs, it has been possible to measure the volume of blood in active circulation through the splanchnic area and its component vascular beds.
2. The volume of blood in the splanchnic bed at the moment of its exclusion from the general circulation was found in 13 dogs to lie between 20 and 50 per cent of the total blood volume.
3. The volumes of blood in the intestinal, hepatic, splenic and gastric components of the splanchnic bed were estimated, and the results expressed as percentages of the splanchic blood volume.
