In recent days, high temperatures have been increasing, and there have been many cases of heat stroke in many places, such as the news of cases of coma and even death due to "heat stroke", which is not an isolated case.
What kind of disease is pyrexia, known as the "heat killer"?
Commonly understood, pyrexia is the most dangerous, the most serious heat stroke, mainly refers to the persistent hot environment, the human body thermoregulatory dysfunction, sweat can not be discharged in a timely manner, the heat accumulation in the organs and muscle tissues, resulting in skin dryness, muscle temperature, and other symptoms, which in turn affects the functioning of the organs and tissues of the whole body, the emergence of local muscle spasms, hyperthermia, sweatlessness, dry mouth, coma, elevated blood pressure, respiratory distress and even multi-organ failure.
The death rate of pyrexia can be as high as 70%, and even if the survivors, nearly 30% of them will have neurological and other systemic sequelae.
Two, it has three prominent features:
Core temperature rise >40 ℃
No sweating
Change in mental status, convulsions or coma
Heat stroke is usually not a sudden onset, the heat stroke is divided into aura heat stroke, mild heat stroke, moderate heat stroke and severe heat stroke 4 stages. The main manifestations of aura heat stroke are dizziness, weakness, profuse sweating, thirst and lack of concentration. Thereafter, if the body temperature rises and fever develops, but there is no shift in consciousness, the stage of mild heat stroke is entered. If there is no intervention, the body temperature will continue to rise, up to a high fever of 40 ℃ to 42 ℃, accompanied by convulsions of the limbs, consciousness disorder, then it enters the stage of moderate heat stroke and severe heat stroke. The most serious heatstroke is severe heatstroke, or pyrexia, usually combined with multiple organ failure.
There is a progression between aura heat stroke and the most severe degree of pyrexia. With timely intervention, most people with heat stroke do not progress to pyrexia.
Like this incident, the patient in the outdoor activities with children home, had dizziness and weakness and other symptoms of heat stroke, but did not take timely measures to adapt, but continue to be in the air-conditioning is not turned on the stifling hot, sunny room, until the "screaming can not be woken up" by family members to find, sent to the hospital, and ultimately led to a tragedy. The tragedy occurred.
In a hot environment, if there is dizziness, headache, weakness, thirst, sweating, panic, chest tightness, poor concentration, uncoordinated movements and other symptoms, but the body temperature is normal or slightly elevated, is the precursor to heat stroke.
If aura heatstroke occurs:
First of all, we should leave the high temperature, high humidity and closed environment as soon as possible, and then go to a ventilated and cool place;
If the condition is not too serious, you can drink some cool beverages moderately, such as light saline water, saline tea water, or cool beverages containing salt;
You can use a cold towel to wipe down the temperature, part of the patient's symptoms can be improved;
Home can be prepared some room temperature green bean soup, also has the effect of summer cooling.
At present, there is no special medicine to treat pyrexia. If you find people around you in a special situation, such as already not clear in the brain, etc., you should move the patient to the shade, undress, wipe the body with warm cool water, or blow with an electric fan, and take them to the doctor in time.
Three, who is easy to hit?
Outdoor work for a long time of sanitation workers, construction workers;
People suffering from chronic diseases, especially cardiovascular diseases;
the elderly and frail, children and pregnant women, etc., are at high risk of pyrexia.
The climatic factors of high temperature and high humidity and intense physical activity are the most important risk factors for pyrexia.
Four, pyrexia focus on prevention, try to avoid high temperature and high humidity environment.
The hot weather need to try to avoid going out in the 11 to 16 hours, such as must go out to do a good job of heat and sun preparation; especially outdoor workers in the arrival of the hot weather to pay attention to heat, timely hydration supplement salt;
Go out and pay attention to the sun, you can wear a wide-brimmed sun hat, sunglasses, etc..
Ensure adequate sleep, so that the brain and body to get fully relaxed, you can wear an eye mask and other ways to improve the sleep environment, so as to ensure the quality of sleep.
