The “dog days” have arrived, and high temperature weather has begun to appear in most parts of our country. For runners, they should pay special attention to “heatstroke prevention and cooling” when running
in high temperature weather. Heat stroke is a disease with related clinical manifestations due to dysfunction of the thermoregulatory center, sweat gland failure and excessive loss of water and electrolytes in hot weather, high humidity and a windless environment.
According to the severity of clinical manifestations, heat stroke is divided into aura heatstroke, mild heatstroke, and severe heatstroke; severe heatstroke is more serious, divided into heat cramps, heat exhaustion, and heat stroke, of which heat stroke is heat stroke The most severe type is characterized by high fever, anhidrosis, disturbance of consciousness and higher mortality. In general, the prime time for emergency rescue is half an hour.
What is heat stroke? What are the performances?
When the human body is exposed to high temperature for a long time, the balance of heat production and heat dissipation of the human body will be out of balance, resulting in the disturbance of body temperature regulation and the failure of sweat glands, and people will suffer from heat stroke.
Mild heatstroke
may manifest as dizziness, headache, flushing, thirst, profuse sweating, malaise, palpitations, rapid pulse, difficulty concentrating, and incoordination Wait.
Severe heatstroke
includes heat cramps, heat exhaustion, and heat stroke, and can present as a mixture of these three types. In severe cases, it can lead to death.
Who is at risk of heat stroke?
The doctor pointed out that all kinds of physical exertion or high temperature environment (generally atmospheric temperature >32??, humidity >60% and poor ventilation conditions) cannot adapt to high temperature environment and Heatstroke is easy to occur when working long hours, strenuous exercise or military training, and without adequate heatstroke prevention and cooling measures.
In addition, patients with obesity, malnutrition, frail old age and chronic diseases are more prone to heat stroke when the room temperature is high and there is no air conditioning. According to statistics, myocardial infarction, cerebrovascular accident and other diseases can increase the incidence of heat stroke by 10 times.
What should I do in case of heatstroke?
1. Immediately transfer the patient to a well-ventilated low-temperature environment;
2. Make the patient lie down and undress. Unfasten or even take off the clothes, wrap the head with a cold towel, turn on the fan or air conditioner, etc. to help the patient cool down; Drinks;
4. Take out an ice pack for ice massage for the patient;
5. For patients with abnormal circulation, high fever, cramps, disturbance of consciousness and other symptoms, help the patient While rapidly cooling down, the patient should be sent to a hospital capable of rescue as soon as possible for further rescue and treatment.
