Be careful of heat stroke! What are the common symptoms? Learn about prevention and on-site first aid knowledge!, Continuous high temperature and extremely high temperature. 3. Heat stroke | high temperature | symptoms
We haven't entered the dog days yet
High temperatures have continued to hit
Facing the "hot and steaming" weather
Reminder to everyone
Heat stroke must be prevented
//
Heat stroke is the most severe condition among heat related emergencies, namely severe heat stroke. It is caused by the imbalance of body regulation function in high temperature and humidity environments, resulting in heat production exceeding heat dissipation, leading to a rapid increase in core temperature, exceeding 40 ℃, accompanied by skin burning, consciousness disorders, and multiple organ dysfunction. It is the most serious type of heat stroke, and once it occurs, the mortality rate is extremely high.
According to the different causes and susceptible populations, heat stroke can be divided into exertional heat stroke and non exertional heat stroke.
//
The climate factors of high temperature and humidity, as well as high-intensity physical activity, are the main risk factors for heat stroke.
Classic heat stroke is mainly caused by high temperature and high humidity environmental factors, usually without intense physical activity.
Labor induced heat stroke is mainly caused by the imbalance between heat production and heat dissipation caused by high-intensity physical activity in the body.
//
1. Elevated body temperature: Elevated body temperature is the main characteristic of heat stroke. The core body temperature of patients is often above 40 ℃.
2. Central nervous system symptoms: Central nervous system dysfunction is the main feature of heat stroke, and severe damage can occur in the early stages, manifested as delirium, drowsiness, seizures, coma, etc; Other abnormal manifestations of the nervous system may also occur, including abnormal behavior, hallucinations, reflexes, and rigidity of the brain. Some patients may experience long-term central nervous system damage in the later stage, mainly manifested as lack of concentration, decreased memory, cognitive impairment, language disorders, ataxia, etc.
3. Other symptoms: headache, nausea, redness of skin, elevated skin temperature, shortness of breath, increased heart rate, muscle spasms or weakness.
//
Heat stroke can be life-threatening, and while attempting to cool the patient down, others around should help make emergency calls.
1. Transfer the patient to a cool place.
2. Regardless of the method used, quickly cool the patient down. If the patient is immersed in cold water in a bathtub; Place the patient under a cold water shower; Spray cold water for watering flowers on the patient's body; Wipe the patient's body with cold water; Cold compress the head, armpits, and thigh roots with a damp towel or ice pack; When the weather is dry, wrap the patient in a sheet or clothing soaked in cold water and blow vigorously with a fan.
3. Patients with heat stroke may experience involuntary muscle twitching. When encountering this situation, it is important to avoid the patient harming themselves. Do not put anything in the patient's mouth and do not attempt to feed the patient water. If the patient experiences vomiting, flip the patient's body to lie on their side to ensure airway patency and avoid aspiration.
//
If the following situations occur, seek medical attention promptly:
If the body temperature continues to rise, even exceeding 40 ℃, timely medical attention should be sought.
2. Headache: When persistent headaches occur in high temperature environments or after heavy physical labor, it is important to seek medical attention promptly.
3. Muscle spasms: Unconscious twitching of the entire body's muscles, especially those in the limbs, should be sought promptly after exposure to high temperatures or heavy physical labor.
4. Fast and shallow breathing: The breathing speed increases, exceeding 20 breaths per minute. The amount of inhalation and exhalation is small, and timely medical attention should be sought.
5. Nausea: If there is a feeling of wanting to vomit but unable to do so, seek medical attention promptly.
If patients find the following situations, they should be immediately sent to the hospital or assisted in calling 120:
1. Coma: loss of consciousness, slow or no response to external stimuli;
2. Extremely weak: feeling weak and almost unable to move;
3. Blurred consciousness: unable to accurately perceive people or things around, such as not knowing where oneself is or what others are saying;
4. Delirium: Mental disorder, talking nonsense;
5. Epilepsy: involuntary convulsions of the muscles throughout the body, without consciousness, and without any response to external stimuli.
//
The key to reducing the mortality rate of heat stroke is prevention.
The most effective preventive measures are to avoid high temperatures and poorly ventilated environments, reduce and avoid risk factors for heatstroke, ensure sufficient rest time, and avoid dehydration, thereby reducing the incidence and mortality rate of heatstroke.
