In vitro effects of inosine-pyruvate-phosphate on P50 values and DPG contents of fresh and stored blood from healthy neonates, symptom-free premature infants and premature infants with respiratory distress syndrome.
A study was made of the effect of a 3-hour incubation with inosine-pyruvate-phosphate (IPP) on the P50 values and 2,3-DPG contents of fresh blood and blood which had stood for 96 h, from healthy adults, term neonates, 1-2-week-old symptom-free premature infants and RDS premature infants. It was found that the P50 value and the 2,3-DPG content could be increased considerably by IPP treatment in both the fresh and the stood blood in the various groups of neonates. The question remains open as to whether the effect of IPP, in significantly improving the O2 transport in neonates, is a consequence of the 2,3-DPG alone or of some other metabolite. In RDS the stimulating effect of the IPP mixture is appreciably lower.
