Abstract
Newborn lambs are delivered by hysterotomy, their respiratory passages occluded, and their umbilical cords ligated. Periodic aortic blood samples taken before and for 15 minutes after ligation demonstrate the accumulation of lactate and potassium in the plasma, an elevation of PCO2, a fall in the pyruvate concentration, and no significant change in the glucose, sodium, chloride, phosphate or free amino acid concentrations.
