PLASMA FREE FATTY ACID AND BLOOD SUGAR LEVELS IN NEWBORN INFANTS AND THEIR MOTHERS

Simultaneous plasma free fatty acid (FFA) and blood sugar levels were determined for fasting newborn infants during the first 24 hours of life, for their cord bloods, and for their mothers at delivery. The following observations were made. In control infants the mean FFA level rose about three times the cord level after birth and was accompanied by a 25% drop in the mean blood sugar level. Thereafter, the mean blood sugar level remained relatively constant, but the mean FFA level varied from 2frac12 to 3 times the cord level. There was no significant correlation between the length of maternal fasting prior to delivery and the infant FFA level; there was, however a significant negative correlation between the length of maternal fasting prior to delivery and the infant blood sugar level at 24 hours of age. High FFA levels occurred in the infants of obese mothers and low levels were observed in infants with delayed respirations, in infants of preeclamptic mothers, and in infants of diabetic mothers.
