Study Details

Brief summary:

Magnesium is a naturally occurring mineral that is important for your body and brain. Magnesium sulfate (study drug) is a medication containing magnesium that is commonly used to improve low blood levels of magnesium. Magnesium sulfate has also proven to be successful in managing pain before and after surgery. However, this drug has primarily been used for pain control in patients undergoing surgery. Patients in the ICU with injuries also need good pain control. Using magnesium may assist in decreasing narcotic (pain reliever) requirements and provide another non-narcotic drug for pain control.

The purpose of this study is to test the effectiveness of continuous, intravenous (into or within a vein using a needle) administration of magnesium sulfate for pain control in trauma patients admitted to the adult Intensive Care Unit. This will be compared to intravenous normal saline (salt solution).

Interventions and Outcome Measures

Arms

experimental: Magnesium Group

The magnesium group arm will receive a 40 mg/kg IBW (maximum 4 g) bolus of intravenous magnesium sulfate, followed by a continuous infusion of 0.5 g/hr for a total of 24 hours.

placebo comparator: Control Group

The control arm will receive the same volume and rate of saline as if they were in the experimental group.

Interventions

Magnesium Sulfate in Parenteral Dosage Form

IV bolus followed by continuous infusion for 24 hours

Normal saline placebo

IV bolus followed by continuous infusion for 24 hours

Primary outcome measure

  • total opioid requirements during study drug infusion [ Time Frame: 24 hours during study drug infusion ]
