Summary and Conclusion Left atrial and proximal aortic blood samples were obtained from 118 normal term newborn infants less than 24 hours of age. PO 2 pCO 2 pH and buffer base were measured to evaluate the effects of early versus late cord clamping at birth. During the first three hours of life, the late clamped infants had a lower paO 2 , and higher paCO 2 , than the early clamped infants. During the first 5 hours of life, both early and late clamped infants had mild metabolic acidosis. The blood pH was the Same in both groups in spite of the lonwer pC0 2 , level in the early clamped infants. There was an addition, lower standard bicarbonate content and greater buffer base deficiet in the early clamped infants.
