Dizziness in summer is not necessarily heat stroke!Be wary of brain infarction!

Summer stays outdoors, and occasionally dizzy and headache. This is a scene that many people have experienced. Many people think of heat stroke as soon as possible. In fact, ischemic stroke can also dizzy. How can these two dizziness be different? Today we ask a doctor to answer this question.

The doctor reminded that if it is not determined to be caused by dizziness, it is recommended to seek medical treatment immediately and do a skull imaging examination to avoid delaying the condition.

Ischemic stroke

Drive more water after sweating, dizzy after playing cards continuously

Recently, the weather was hot. For a week in a row, Mr. Lin went to the park to play cards every day, sweating more water and less water. One night, he suddenly dizzy and almost fell. The family quickly sent him to the emergency department of Zhongshan Hospital affiliated to Xiamen University. After examination, it was diagnosed with ischemic stroke (also known as cerebral infarction), which was mainly caused by hypoxia and brain tissue damage. After emergency intervention treatment, his dizziness disappeared.

Director Chen Xingyu, the Department of Neurology, Zhongshan Hospital affiliated to Xiamen University, explained that human brain tissue requires blood to provide oxygen, just like the woods need water to moisturize. When the human body is short of water, it will cause blood viscosity, brain injection (blood full of blood in the brain), and brain brain. Ischemic and hypoxia will cause ischemic necrosis of brain tissue. High temperature weather is also one of the factors that induce ischemic stroke. Therefore, patients with ischemic stroke may occur in high temperature weather. To prevent such incidents, we must first prevent cerebrovascular diseases. Secondly, drink plenty of water in summer to ensure sufficient water in the body.

If these "stroke 120" phenomenon can be determined to be stroke

Chen Xingyu said that with a family history of cerebrovascular diseases over the age of 60 and suffering from hypertension, hyperlipidemia, diabetes, coronary heart disease and other diseases, it is a risk factor that induce stroke. Obesity, with bad living habits such as smoking and alcoholism, and long -term tension may also cause stroke.

After dizziness, determine whether it is ischemic stroke, depending on whether there is a "stroke 120" phenomenon, that is, see a face, two arms, and listening to language. Looking at the face, it is mainly to see if the face is "crooked and crooked", especially whether the two sides are consistent when smiling; seeing the two arms, mainly observing whether the arm is raised in parallel. Check whether the patient's speech expression ability is as usual to see if there is unclear speech and difficulty in expression.

"Once the" stroke 120 "phenomenon appears, you must seek medical treatment in time." Chen Xingyu reminded that stroke is one of the main causes of human death and disability globally. Once the stroke is on the spot, it must be 4-6 hours at the golden window. Internal thrombolysis, if this time window exceeds this time, it needs to be intervened and opens the cerebral blood vessels. Otherwise, it will leave severe sequelae, such as hemiplegia.

Heat stroke

The cool place on the construction site stays in dizziness on the upper body of the upper body for a long time

Some time ago, Xiaofang (pseudonym) needed to go to the construction site due to work. Although she was staying in a cool place, she was still upper body, and dizziness symptoms appeared before leaving the scene. After salt, it improved.

Ma Bingfen, the attending physician of the Department of Siming Hospital of Xiamen University Affiliated Hospital, said that Xiaofang's condition was mild heat stroke. In an environment with heat, high humidity, and poor ventilation, the human body temperature regulation center disorders will cause problems such as sweat gland failure, a large amount of sweat, causing hydrolysis disorders.

Existence of heat dissipation disorders can easily lead to heat stroke

According to Ma Bingfen, according to the degree of severity, heat stroke is divided into three types: heat spasm, thermal failure, and thermal ejection disease. Thermal spasm (that is, mild heat stroke) with dizziness and headache as common symptoms. Thermal failure (moderate heat stroke) mostly appears among patients with chronic diseases and cerebrovascular and cerebrovascular diseases. Such people may produce one or two liters of sweat in a hot weather, and in severe cases, it may be as high as 4 liters. The symptoms of fever (severe heat stroke) are that the center temperature of the patient is often higher than 40 ° C, and even high fever and conscious disorder occur.

Ma Bingfen said that long -term labor will generate a lot of calories. When people are at a higher temperature than their own temperature, their body temperature will be higher. If there are heat dissipation disorders, for example, the unprepared clothes and the surrounding environment are hot and humid, and the sweat cannot evaporate and it will easily lead to heat stroke. Those who have worked and live in air conditioners for a long time have poor heat adaptability. Suddenly to the hot outdoor campaign for a long time, it is more likely to cause heat stroke.

【remind】

Drink water after heat stroke

Symptoms will be more serious

Ma Bingfen reminded that once the heat stroke symptoms occur, they should be quickly transferred to a ventilated and cool place, and wipe it with cold water for undressing. Those with severe heat stroke should be immersed in cold water (except the head), and oral electrolyte solution (such as oral replenishment salt solution). Once high fever, shock, consciousness disorder, etc. occur, you should immediately go to the hospital for further first -aid measures such as cooling in in vivo and replenishment.

It should be noted that it should not drink a lot of water after heat stroke, because the water will dilute the salt in the body, causing the symptoms of low sodium. The supplementary liquid can be an electrolyte drink, but there must be no polysaccharides.

【Suggest】

Two dizziness is different

Unable to distinguish to go to the hospital

Ma Bingfen said that there is a difference between dizziness and dizziness in ischemic stroke after heatstroke. It must be confused, otherwise it will easily lead to neglected stroke and cause serious consequences.

Ma Bingfen said that in addition to dizziness and headache, heatstroke people may also be accompanied by muscle cramps, stomach pain and other acute abdomen manifestations, commonly in people who drink a lot of water after exercise.Generally, after the transfer of such people to cool down and oral replenishment, the symptoms can be relieved quickly.Symptoms such as ischemic stroke dizziness and headache are generally persistent, and may also be accompanied by hemiplegia, unfavorable words, and skewed mouth.However, in patients with heat stroke, there are indeed some people in the case of ischemic stroke. If the phenomenon of "stroke 120" cannot be appointed, it is recommended to seek medical treatment immediately, further do the head imaging examination, clarify the cause as soon as possible, and treat symptomatic treatment.
