Key result
Open-heart surgery was associated with a significant fall in serum magnesium during the first postoperative day, which normalized from the second day onwards.
Why the study?
Do serum magnesium levels fall significantly after open-heart surgery requiring routine supplementation?
Population

Transient hypomagnesemia after open-heart surgery normalizes by day 2; leaves open whether routine supplementation improves outcomes in this observational cohort.

Do serum magnesium levels fall significantly after open-heart surgery requiring routine supplementation?
Serum magnesium levels normalize by the second postoperative day after open-heart surgery, suggesting that routine pre-, per-, or postoperative magnesium supplementation is not indicated.
Vejlsted et al. (1978) conducted an observational in Open-heart surgery. Open-heart surgery was evaluated on Serum magnesium level. Open-heart surgery was associated with a significant fall in serum magnesium during the first postoperative day, which normalized from the second day onwards.
