During the storage of whole blood or packed red cells generic 10 gm fucidin with amex, potassium leaks from erythrocytes into the extracellular fluid and can accumulate at concentrations of 40–80 mEq/L generic fucidin 10gm overnight delivery. Once the RBCs are returned to the in vivo environment, the potassium quickly re-enters RBCs. However, during rapid blood transfusion tran- sient hyperkalemia may result, particularly in patients with renal insufficiency. The transient hyperkalemia, particularly in the presence of hypocalcemia, can lead to cardiac dysfunction and arrhythmias. In patients with renal insufficiency, potassium load can be minimized by the use of either freshly obtained blood or washed packed RBCs. Hypokalemia can also result from massive blood transfusion due to re- entry of potassium into RBCs and other cells during stress, alkalosis, or massive catecholamine release associated with large volume blood loss. Therefore, potas- sium levels should be monitored routinely during large-volume blood transfu- sions. During the storage of whole blood, an acidic environment occurs due to the accumulation of lactate and citrate with a pH in the range of 6. Rapid transfusion of this acidic fluid can contribute to the metabolic acidosis observed during massive blood transfusion. However, metabolic acidosis in this setting is more commonly due to relative tissue hypoxia and anaerobic metabolism due to an imbalance of oxygen consumption and delivery. The anaerobic metabolism that occurs during states of hypovolemia and poor tissue perfusion results in lactic acidosis. The re-establishment of tissue perfusion and homeostasis is a much more important factor in re-establishing acid–base balance. In contrast, many patients receiving massive blood transfusion will experi- ence a metabolic alkalosis during the posttransfusion phase. This is due to the conversion of citrate to sodium bicarbonate by the liver and is an additional reason to avoid sodium bicarbonate administration during massive blood transfu- sion, except in cases of severe metabolic acidosis (base deficit 12). Rapid infusion of large volumes of cold (4 C) blood can result in significant hypothermia. When added to the already impaired thermoregulatory mechanisms in burn patients, this can result in significant hypothermia. Potential complications Anesthesia 131 of hypothermia include altered citrate metabolism, coagulopathy, and cardiac dysfunction.
