Mobile Stroke Unit Reduces Disability, Research Results

According to Denise Mann HealthDay Reporter

Thursday, September 9, 2021 (HealthDay News)

Count every second after holding stroke, And quick response mobile stroke The unit can start thrombus destruction Drug New research has been discovered that quickly avoids potentially permanent damage.

mobile stroke The unit is a special ambulance equipped with imaging equipment and staffed with specialists who can diagnose and treat. stroke The moment before arriving at the hospital. generally, stroke You have to wait until they arrive in the emergency room for evaluation and treatment, which can be valuable time.

In this study, people treated with mobile phones stroke Units had low levels of disability after their 3 months stroke, Compared to those who were treated when they arrived at the ER.

“”Bring stroke Treatment of patients using mobile stroke Unit … More patients are treated, treated more quickly, and most importantly, less, etc. paralysis, Loss of language Or intelligence. This is less of a stroke injury than standard management, where treatment is not initiated until after the arrival of the emergency department. “

Grotta is the director of stroke research at the Clinical Institute for Research and Innovation at the Memorial Hermann Texas Medical Center in Houston, and the founder and director of the Houston Mobile Stroke Unit Consortium.

A study found that for every 100 people who had a stroke and were treated with a mobile unit, 27 had less disability and 11 had a full recovery.

Save more than 30 minutes

The study also found that the median time from the onset of stroke to the start of treatment was 36 minutes shorter (72 minutes vs. 108 minutes). And three months later, 55% of mobile unit patients returned to normal activity, compared to 44% of standard emergency care patients.

Ischemic stroke The most common type of stroke. They are, clot cut Turns off the blood supply to the brain. Tissue plasminogen activator (tPA), a thrombus-destroying drug, is very effective in preventing persistent disorders such as: paralysis Or the problem of speech after a stroke. However, the sooner it is, the better, only if it is administered within 4.5 hours of the onset of stroke.

The study began in 2014 with the launch of the UT Health Mobile Stroke Unit in Houston and continued until 2020. It included more than 1,500 patients and was expanded to six cities. Overall, 1,047 people were considered eligible to receive tPA. Of these, 617 received mobile unit care.

People treated with mobile units were more likely to receive this drug during the important first hour after a stroke. According to Grotta, up to 70% of people treated with tPA in the first hour recover without permanent damage.

He added that time is the brain.

“When blood and the oxygen it carries are deprived, brain cells die within minutes,” Grotta said. “Opening the arteries as soon as possible is the key to successful treatment.”

Cost running One of these units is a consideration. Grotta said the mobile stroke unit costs about $ 1 million to buy and about $ 500,000 a year to operate. “It’s expensive, but it saves lives and money on the health care system by reducing the need for long-term disability care,” he said.

Appropriate repayment from insurance companies is required to spread this throughout the country. “This is what we are working on,” Grotta said.

This study was published in the September 9th issue. New England Journal of Medicine..

The new findings are consistent with recent studies showing that the staff of mobile stroke units can perform emergency treatment in stroke patients, significantly improving their chances of survival and good recovery.Procedure, endovascular thrombectomy can be removed on a large scale Blood clot Blocks blood flow to the brain.

Like the house of fire

Dr. Kennedy Leeds, a professor of cerebrovascular medicine at the University of Glasgow, Scotland, said the introduction of a mobile stroke unit would be a milestone in stroke treatment. He wrote an editorial accompanying the study.

Lee likens stroke treatment to dealing with a house with a fire. “Wait 90 minutes. Damage may not be repairable.”

These are “great results,” agreed Dr. Deepak Bart, Secretary-General of the Interventive Cardiovascular Program at Brigham and Women’s Hospital. heart Boston Vascular Center.

“The mobile stroke unit provides treatment for patients who may have a stroke,” said Bat, who has nothing to do with the new study. “They can make a diagnosis much faster than if the patient were taken to a local emergency room, and can immediately provide a powerful thrombus-destroying drug therapy, so the patient is initially evaluated with the hospital. Starts from there. “

It is imperative to be aware of the signs of a stroke warning and act swiftly, Bart said.Think Fast-Acronyms for Signs of Stroke: Face Dangling, Arms Weaknesses Or the difficulty of the speech means it’s time to call 911, he said.
