The oxygen-release capacity of red blood cells in insulin-dependent diabetics after artificial pancreas.
Oxygen-release capacity of the red blood cells was investigated in non-acidotic insulin-dependent diabetics before and after the achievement of strict metabolic control with the aid of the artificial pancreas. P50std (oxygen tension at 50% oxygen saturation) values were low in basal condition and returned to normal after the 24-h treatment period. No significant changes were observed in the content of red cell 2,3-diphosphoglycerate nor in the acid-base balance. Only the labile form of glycosylated hemoglobin showed significant decreases after treatment. These results suggest that insulin-dependent diabetics may have a state of relative tissue hypoxia which can be easily overcome by the achievement of strict metabolic control.
