There is no time to waste when it comes to stroke. The more time that passes between stroke onset and treatment, the worse the outcome is for the patient. A study designed to test the benefits of early administration of magnesium sulfate suggests that stroke patients may not have to wait until they get to the hospital for treatment — paramedics may be able to start therapy as soon as stroke is suspected. Although the drug did not improve outcome in stroke patients, the study demonstrated the feasibility of early therapy in the ambulance. The results were published in the New England Journal of Medicine and the study was funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
