Cerebral hemorrhage in winter is "fiercer than a tiger". What is the culprit?

Why do so many people have cerebral hemorrhage in winter?

1. Cold and cooling make sympathetic nerves excited, and catecholamine secretion increases, which leads to punctate bleeding and brain edema of small blood vessels due to hypoxia and necrosis, and massive bleeding occurs when they are fused into blocks.

2. Cold can cause the decrease of coagulation factors in blood and the increase of fibrinolytic enzyme activity, which is easy to lead to cerebral hemorrhage.

3. When the temperature is too low, the human body releases too much adrenaline, which leads to the contraction of cerebral vessels and the increase of blood pressure.

4. The elasticity of blood vessels decreases and the fragility of blood vessels increases in the elderly. Blood pressure suddenly rises, and small blood vessels rupture and bleed.

In short, when the weather suddenly turns cold, especially from June 5438+ 10 to February 65438+2, high-risk groups such as hypertension, especially the elderly, should effectively control their blood pressure, maintain emotional stability, and reduce strenuous outdoor activities, thus effectively preventing and reducing the occurrence of cerebral hemorrhage.

What are the symptoms of cerebral hemorrhage that need high vigilance?

1, dizziness and headache

Dizziness and headache are the main symptoms of early cerebral hemorrhage. When increased intracranial pressure, the pain can spread to the whole head. Dizziness and headache occur at the same time, which can occur briefly, repeatedly or gradually, and some of them are accompanied by nausea, vomiting, instability and even falling to the ground.

2. Hemiplegia

After cerebral hemorrhage, the corresponding nerve function is damaged, thus losing the adjustment of one limb and causing hemiplegia. Some patients with cerebral hemorrhage will have numbness in one side of the body, or numbness in the face, arms and fingers, accompanied by weakness, unstable walking and inconvenient activities.

3. Vague pronunciation

Vague speech, suddenly unable to speak when talking with others, or unable to understand each other's words. This situation is caused by blood pressure fluctuation or brain dysfunction, and it is a great precursor to cerebral hemorrhage or subarachnoid hemorrhage.

4, blurred vision

Due to the damage of optic nerve, the retina is ischemic and anoxic. At this time, patients will have transient blackness at the moment, unable to see clearly or blurred with double images, some will return to normal after a few minutes, and some may be blind.

5, mouth askew, drooling

When the brain is abnormal, other nerve functions will be out of control, resulting in problems such as drooling, crooked mouth and difficulty swallowing.

Remembering these critical moments may save your life!

The occurrence of cerebral hemorrhage is often unpredictable, usually with acute onset and dangerous condition, so people around you must take first aid measures to win golden time for patients. When the patient has symptoms related to cerebral hemorrhage, call 120 as soon as possible. Secondly, don't move the patient's body at will, let the patient lie flat and tilt his head to one side to prevent sputum and vomit from being inhaled into the trachea. For patients wearing ties and belts, they should be loosened quickly to keep the patients breathing smoothly and the air circulating. You can also cover the patient's head with a cold towel to reduce the amount of bleeding, and then wait for the ambulance to arrive.
