Red cell sodium concentration as an indicator of cellular injury in clinical shock.
Red cell sodium concentration has been found to be elevated in shock. The significance of this change relative to survival and the possible sources for this increase were examined. Twenty patients in shock had red cell sodium levels compared to shock-related variables and to conditions known to increase red cell sodium levels in vitro. There was no difference noted in red cell sodium elevations between survivors and nonsurvivors. There was a highly significant correlation with transfusions of banked blood and a significant correlation with the administration of digitalis. There was no correlation with the type, duration, or severity of shock. Changes in the sodium gradients across red cell membranes in clinical shock are not good indicators of the general cellular injury of shock.
