Abstract
The increasing reliance placed upon the pH of capillary blood as an indicator of fetal condition during labor and delivery has made it desirable to compare the composition of blood from this source with that present in the major vessels supplying the central nervous system of the fetus. Discrepancies in the composition of blood obtained from central and peripheral sites have been appreciated in the newborn (Gandy et al., 1964). They have been particularly pronounced in the immediate neonatal period among infants in poor general condition. Since the scalp of the fetus while passing through the birth canal is frequently affected by edema and venous congestion, it seemed plausible that blood obtained from this source was only of limited value in the assessment of the acid-base state.
