Assoc. Prof. Dr. Nguyen Huy Thang, Head of the Department of Cerebral Vascular disease-People's Hospital 115 (Ho Chi Minh City), so warned after information many young people spreadtrend"Getting Pen" on social networks.
The doctor warned that he pressed his neck to squeeze the carotid artery in both sides just to find the feeling of "criticism" to be leaned away, lost consciousness in a few seconds is dangerous actions.
Accordingly, "catch pen" is the keyword to be searched on social networks.In the videos that appear mostly students with the action of a hand user pressing strongly on the carotid artery in the neck of the other person.After that, the Indian person will have a drowsiness, lack of alertness, even fainting until he is called to wake up.
With this action, Dr. Thang analyzed blood supply to the brain with 2 main blood vessel systems.In particular, the two artery arteries (previous circulation) are responsible for 70% -80% of the needs of the brain and the artery of living-the background (the next circulation) is responsible for 20% -30% of the remaining blood demand.
"The front-and-boned blood vessels are linked together via the Willis polygon (like a traffic cycle) to ensure the blood demand for the brain is always stable when one side has a problem.There, at the two artery arteries in the neck, there are sinus sinuses that have the effect of adjusting the heart rate and blood pressure " - Dr. Thang said.
Doctors warn the use of hand to press on the neck to squeeze the carotid artery in the two sides just to find the feeling of "criticism" to be leaned away, losing consciousness in a few seconds is dangerous actions.By tightening the two sides of the artery will cause serious reduced brain perfusion (due to 70% -80% of the blood on the brain).If you leave your hands quickly, it will cause dizziness, fainting, loss of consciousness.If the pressing is too long, it may cause anemia stroke, especially when the previous blood vessel stenosis is available (but do not know);Or it can also cause brain damage due to improvement syndrome.In particular, the neck pressing causes sinus irritation can slow heart rate, even cardiac arrest.
"Before that, I also encountered a case of a young woman, hospitalized because of a weak person.The boy clung to the neck. This is a dangerous job that needs to be prevented on social networks.fun activities, but not "naughty" - the doctor emphasized.
