Registered summary

In patients with critical illness, such as severe infections, heart attacks, or respiratory failure, most intensive care units (ICUs) measure magnesium levels and give supplemental doses of magnesium when levels are below certain targets. However, the best targets are unknown. The goal of this clinical trial is to study protocols for magnesium supplementation in people with critical illness, comparing a protocol with higher target level to a protocol with a lower target level. The full summary is on the listing.
