Magnesium supplementation during cardiopulmonary bypass to prevent junctional ectopic tachycardia after pediatric cardiac surgery: a randomized controlled study.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

The researchers analyzed the role of magnesium sulfate (MgSO(4)) supplementation during cardiopulmonary bypass in pediatric patients undergoing cardiac surgery, assessing the incidence of hypomagnesemia and the incidence of junctional ectopic tachycardia.

Who Took Part

The study group was 99 children.

PubMed indexes the participants as infants, young children, children and teenagers, both men and women.

The researchers performed a randomized, double-blind, controlled trial in 99 children.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

The children were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

Some children received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

The subject headings attached to it are Anti-Arrhythmia Agents, Cardiopulmonary Bypass, Magnesium, Magnesium Sulfate, Postoperative Complications and Tachycardia, Ectopic Junctional.
