title: Increase of fetal arterial blood temperature by reduction of umbilical blood flow in chronically instrumented fetal sheep.
abstract: The effect of reduced umbilical blood flow rate on fetal core temperature was investigated in five chronically instrumented fetal sheep (gestational age 124 days). On average, fetal-maternal temperature difference increased 0.13 +/- 0.02 degrees C when blood flow rate was decreased to about 1/3 of normal (248 +/- 69 ml min-1) for 30 min. The small temperature rise is the consequence of predominant heat dissipation through the placenta, and of diminished oxygen consumption.
