Abstract: | The effect of prostaglandin on the affinity of hemoglobin for oxygen was tested on human blood , using six different prostaglandins at several dosage levels in fresh heparinized blood from normal donors and in stored citrated blood, and using prostaglandin E2 on the blood from four seriously ill patients. No significant alterations in the affinity of hemoglobin for oxygen were dtected. A very small decrease in oxygen affinity in stored blood with high doses of prostaglandin was not statistically significant and would be of no physiologic significance even if real.We conclude that under the circumstances of this experiment prostaglandins do not alter the affinity of hemoglobin for oxygen in human whole blood . |
