The risk of stroke increases when the weather turns cold.


     The sudden cold change of weather causes blood vessels to constrict, increasing blood pressure and leading to the risk of brain hemorrhage. The increase of stroke in the cold season is very worrying, we need to know the information and soon take more effective prevention and control measures.

In the past 2 weeks, Bac Giang General Hospital has recorded nearly 20 emergency cases continuously due to stroke. Among the diseases that cause high death for adults, stroke ranks third, after cancer and heart disease. According to the Ministry of Health, each year, there are more than 200,000 strokes in Vietnam and the increase increases during the change of season and cold weather.

* High mortality rate without timely emergency treatment.

Stroke patients are not treated in time for the “golden time”, but too late, the mortality rate is very high. In the case of patient N.T.L. in Ngo Quyen Ward, one of the patients admitted to the Bac Giang General Hospital said that about a dozen days earlier, she woke up at 5 am, when she opened the door, she suddenly felt dizzy and wanted to fall and was lucky. discovered in time.

After that, she went to the hospital for examination, diagnosis and stroke results, but fortunately, she received emergency care in time in the “golden time”. Doctors have prescribed her to take fibrinolytic drugs and so far her health has recovered significantly.

The head of the emergency department said the reason for the increased risk of stroke in the cold season is because blood vessels lose elasticity when the temperature drops, thereby narrowing the lumen and leading to poor blood flow to the brain. Moreover, when the blood vessels constrict, we are more likely to increase blood pressure and increase the pressure in the blood vessels.

In particular, people with atherosclerotic or thrombotic complications are prone to occlusion of blood vessels, or even rupture of blood vessels, leading to cerebral hemorrhage, stroke and have a higher risk of serious complications or even death. Doctors recommend that patients should be taken to the hospital in the first 3-4 hours after a stroke to receive timely treatment, at which time the chances of survival and recovery will be higher. If you have a history of high blood pressure, heart disease, etc., your family should take the initiative to call an ambulance or take them to the hospital right away.

* How to prevent stroke when it turns cold.

You can prevent the risk of stroke when it turns cold with some of the following suggestions:

– Control underlying diseases with risk of stroke such as controlling blood pressure, blood sugar, blood fat.

– When going outside, you need to keep your body warm and when it’s cold, don’t get up early to exercise.

– Elderly/middle-aged people need to have regular check-ups for preventive advice.

– If you see a loved one having one of the stroke symptoms, you must call for help and call an ambulance immediately, then take the patient to the nearest hospital or medical facility with enough emergency facilities.

When waiting for an ambulance, the patient’s family should keep the surrounding environment well-ventilated to help them breathe well. Then place the patient on a flat surface with a firm enough surface for balance, otherwise they lie on a mattress with a deep depression and avoid moving so as not to make the brain hemorrhage worse.

If the patient shows signs of vomiting or any other signs of impaired consciousness, remember to put them in a safe position to protect the airway, by removing all mucus (if any) from the patient’s mouth. . In case the patient is still awake, the family members support them to lie down in the most comfortable position and monitor the reactions.

Currently using fibrinolytic drugs, which dissolve blood clots and open cerebral blood vessels to provide emergency treatment for stroke patients. However, the drug only works optimally at a certain “golden” time, which is from 3 to 4.5 hours from the time when there are signs such as numb tongue, distorted mouth, difficulty speaking, blurred vision, headache. …

Therefore, we need to detect early signs of stroke and bring patients to the hospital early to ensure the best treatment results. If the golden period is exceeded, the patient will not be able to apply fibrinolytic drugs.
