Fructose infusions were administered to parturients with healthy term fetuses at a speed of 1 g/min for 106 on the average. The results confirm that fructose has the expected properties. The blood glucose and FFA levels show that a substantial part of the infused fructose is indeed stored and that only a small portion is used to cover immediate energy needs. This positive result is predominant by a considerable degree of acidosis arising in the parturient in spite of the fact that fructose was infused at a slower rate than in the majority of papers published so far. Since the fructose infusions were intended for premature fetuses, which already have an increased tendency toward acidosis, the results confirm the unsuitability of such a treatment.
