Hemodynamic responses to hypovolemia were investigated in unanesthetized, unstressed fetal lambs and in acute fetal and neonatal preparations. The unstressed fetus tolerated twice the amount of blood loss of the acutely studied fetus or newborn lamb and with a lesser hypotension. Hemodynamic behavior of the newborn lamb and fetus anesthetized with pentobarbital during hypovolemia was markedly different from that of the fetus studied under spinal anesthesia or chronically. Besides tolerating… CONTINUE READING
