Outcome Measures
Primary Outcomes (1)
Modified Rankin Scale
Modified Rankin Scales (mRS) is a measure of global disability. Total Scale range is 0-6, with lower values indicating better outcomes. 0 No symptoms at all 1. No significant disability despite symptoms; able to carry out all usual duties and activities 2. Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance 3. Moderate disability; requiring some help, but able to walk without assistance 4. Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance 5. Severe disability; bedridden, incontinent and requiring constant nursing care and attention 6. Dead
3 months after stroke onset

Study Arms (2)
Magnesium Sulfate
EXPERIMENTALMagnesium sulfate (Mg) was administered intravenously with a 15 minute bolus load followed by a 24 hour infusion. The bolus-loading dose consisted of 4 grams Mg in 54 ml normal saline. The maintenance infusion contained 16 grams Mg diluted in 240 ml 0.9% normal saline, infused at 10 ml/hr for 24 hours. Paramedics in the field initiated the bolus-loading dose, administered at 216 ml/hr over 15 minutes through a rate controlled IV infusion set. The maintenance infusion was initiated in hospital immediately upon completion of the loading dose.
Normal saline
PLACEBO COMPARATORNormal saline was administered intravenously with a 15 minute bolus load followed by a 24 hour infusion. Paramedics in the field initiated the bolus-loading dose of 54 ml normal saline, administered at 216 ml/hr over 15 minutes through a rate controlled IV infusion set. The maintenance infusion was initiated in hospital immediately upon completion of the loading dose at 10 ml/hr for 24 hours.
Interventions
Paramedics initiate a loading dose of 4 grams magnesium sulfate IV over 15 minutes, followed after hospital arrival by a maintenance infusion of 16 grams magnesium sulfate IV over 24 hours.
Paramedics initiate a loading dose of placebo normal saline IV over 15 minutes, followed after hospital arrival by a maintenance infusion of placebo normal saline IV over 24 hours.
Eligibility Criteria

- Known second or third degree heart block with no pacemaker in place
- Major head trauma in the last 24 hours
- Recent stroke within prior 30 days
- Patient unable to give informed consent and no available on scene consent or assent provider
