In order to prevent hypokalemia during and after perfusion, serum potassium, red cell potassium and urinary potassium were observed in thirty patients who were performed heart surgery with bubble oxygenator. At the same time, serum glucose level, Insulin level, free fatty acid level, Triglyceride level and Cathecholamine level in urine were calculated.
The results were as follows.
1) The serum potassium and the red cell potassium levels were decreased during perfusion and gradually recovered after perfusion. Urinary potassium was low measured.
2) The serum glucose level was significantly high during perfusion. On the contrary, during perfusion Insulin secretion was inhibited and after perfusion apparently elevated.
3) During perfusion, the free fatty acid level was elevated and Triglyceride level was declined and respectively recovered to normal level after perfusion.
4) High average value of Cathecholamine in urine was obsered during perfusion.
5) The decrease in serum potassium was probably a consequence of its pooling in extracellular space, because of decrease in red cell potassium and low urinary potassium loss.
