Brief Summary

The purpose of this study is to determine if intravenous magnesium sulfate treatment is effective in reducing the length of stay and pain in children with sickle cell disease suffering an acute vaso-occlusive episode.

Detailed Description

Sickle cell disease is a group of complex, chronic disorders characterized by hemolysis, acute vaso-occlusive episodes (crises), unpredictable acute complications that can be life-threatening, and the variable development of chronic organ damage. Administration of magnesium sulfate has the potential to reduce hemolysis since it induces negatively charged chloride ions and water entry to the cell. To date only one non-randomized, non-blinded, single arm study with only 19 children evaluated the effect of magnesium on length of stay in the hospital of children with sickle cell disease.

In this randomized, double blind, two-arm placebo controlled study, children with sickle cell disease admitted for a vaso-occlusive crisis will receive intravenous magnesium sulfate or placebo every 8 hours during their stay in the hospital , along with pain management. We will measure length of stay (LOS), pain, adverse effects, and the total amount of narcotics required for pain control.
