Abstract

The authors measured visceral temperature and blood flow in order to assess metabolic protection by hypothermic circulatory arrest (HCA). HCA was applied in a macaque monkey model, cooling to 12 degree C and maintaining 30 min of HCA. Cooling was effected by cardiopulmonary bypass (CPB) with blood heat exchange, or by surface ice packs. Rapid cooling occurs during CPB for liver and kidney, cooling to a lower level and more predictably than for other organs. Following HCA, rewarming on CPB was rapid and uniform. Perfusion (radioactive microsphere technique) rates to brain, stomach and intestine increased while those to kidney, liver and spleen decreased during CPB. Following HCA, organ perfusion tended to decline.
