| Abstract |
|
During a six month period in 1985, we evaluated the changing patterns of plasma calcium and magnessium level in 14 patients undergoing open heart operation for correction of congenital heart disease. Magnesium and phosporus were measured with spectrophotometer and total calcium with Gilfor 203-S autonalyzet. Ionized calcium was calculated by equation of (6 X Ca + (P/3))/(P+6). Total calcium and ionized calcium values were 8.47+/-0.75 mg%, 4.77+/-0.90mg% at control. They decreased significantly during bypass period and then rose progressively to reach control level at postbypass period. Magnesium levels were 2.2+/-0.39mg% at control, 2.0+/-0.40mg% at prebypass period. 2.80+/-0.98mg% bypass and 2.1+/-0.55 mg% at postbypass period respectively.
It was maintained at higher level during bypass and reached to control value during postbypass period. |
