- Barthel Index measure of activities of daily living [ Time Frame: 3 months ] [ Designated as safety issue: No ]
- NIH Stroke Scale measure of neurologic deficit [ Time Frame: 3 months ] [ Designated as safety issue: No ]
- Stroke Impact Scale measure of stroke-specific quality of life [ Time Frame: 3 months ] [ Designated as safety issue: No ]
- Mortality [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
- Symptomatic hemorrhagic transformation [ Time Frame: 4 days ] [ Designated as safety issue: Yes ]
- Recurrent ischemic stroke [ Time Frame: 90 days ] [ Designated as safety issue: Yes ]

Detailed Description:
Stroke is the third leading cause of death and the leading cause of adult disability in the United States. Each year, more than 750,000 Americans suffer a symptomatic stroke.
Currently, rt-PA is the only approved treatment for acute ischemic stroke; however, its usefulness is limited because most patients cannot reach medical attention within the necessary 3-hour time window. In addition, rt-PA cannot be given in the field because it is contraindicated for treatment of patients with brain hemorrhage.
The purpose of this multi-center, randomized, double-blind trial is to demonstrate that paramedic initiation of the neuroprotective agent magnesium sulfate in the field is an effective and safe treatment for acute stroke. This study will analyze magnesium sulfate, an experimental therapy for stroke, versus placebo among ambulance-transported patients with acute stroke. This trial will also demonstrate that paramedics can safely, effectively, and rapidly start neuroprotective therapies for stroke.
