![]() In a mobile stroke unit, a specialized ambulance is equipped with a CT scanner, a paramedic, a critical care nurse, a CT technologist and a neurologist in person or by telemedicine. This takes a certain amount of time from the patient's symptom onset which prompted the 9-1-1 call. That is why patients need a CT scan to confirm the type of stroke before receiving tPA.Įvery second counts, in the current standard of care, patients who experience stroke-like symptoms and call 9-1-1 arriving to the hospital by ambulance are assessed by clinical examination and imaging (CT or MRI scan) in the Emergency Department. But tPA is not indicated and could hurt a patient's chances if they are having a hemorrhagic stroke, in which a blood vessel ruptures. Past research showed the sooner that a clot-busting tPA drug is given after an ischemic stroke - one in which a clot is blocking blood flow - the better patients fare. Its better outcomes could offset the increased costs of a mobile stroke unit." "Our study shows pre-hospital clot-busting is a promising, evolving approach to providing tPA stroke therapy. "Time is brain in acute stroke after vascular collaterals fail, and faster treatment yields better outcomes," said May Nour, M.D., Ph.D., lead researcher, interventional neurologist and director of UCLA's Mobile Stroke Rescue Program. ![]() ![]() This preliminary study showed that three months after stroke, 182 out of every 1,000 patients treated before arriving at hospital were less disabled, including 58 patients who had zero disability, compared to people who received treatment after reaching the hospital. About half of the participants received the clot-busting drug at the hospital, and half received it while still in the ambulance. Researchers analyzed results from 658 stroke patients who were treated with tPA - a drug that dissolves blood clots.
