Now in the middle of summer, the high temperature weather constantly, it is easy to trigger heat stroke, some people will be dizzy, some even faint fainting. Heat stroke can cause unpredictable consequences if not treated in time, and must be treated in time. A. What is heatstroke? Heat stroke medically becomes pyrexia, which refers to the dysfunction of the body’s thermoregulation caused by high temperature and the excessive accumulation of heat in the body, which causes damage to the nervous organs. Heat stroke in the classification of heat stroke is severe heat stroke, which is a fatal disease with a high death rate. The disease usually occurs in summer when high temperatures are accompanied by high humidity. Inadequate adaptation to the high temperature environment is the main cause of the disease. In an environment with elevated atmospheric temperature (>32°C), high humidity (>60%) and no wind, long working hours or strong physical labor, and without adequate measures to prevent heat stroke, people lacking adaptation to the high heat environment are prone to heat stroke. The susceptibility factors include: ① High ambient temperature The body obtains heat from the outside environment. (2) Increased heat production by the body, such as heavy physical labor, fever, hyperthyroidism and the application of certain drugs (amphetamines). ③ Heat dissipation disorders such as high humidity, excessive obesity or wearing clothes with poor air permeability, etc. ④ Sweat gland dysfunction is seen in patients with systemic sclerosis, scar formation after extensive skin burns or congenital sweat gland deficiency. Symptoms of heat stroke: 1. Aura of heat stroke: headache, blurred eyes, tinnitus, dizziness, thirst, palpitations, normal or slightly elevated body temperature in a hot environment. 2. Initial stage of heat stroke: profuse sweating, thirst, obvious fatigue, weakness of limbs, dizziness, chest tightness, nausea, inattention, numbness of limbs, etc., with normal or slightly elevated body temperature. 3, mild heatstroke: body temperature above 38 ℃, flushed into pale, sweating, wet and cold skin, decreased blood pressure, increased pulse rate. 4, severe heat stroke: also known as heat exhaustion, manifested as cool skin; excessive sweating; nausea, vomiting; dilated pupils, profuse sweating, wet and cold skin, body temperature increased to 38 ℃ or more, blood pressure dropped, pulse rate increased; abdominal or limb cramps; often accompanied by fainting, coma, hyperthermia and even loss of consciousness. How to give first aid in case of heat stroke? 1.Moving The initial stage of heat stroke should be quickly to a ventilated and cool place, lie down and unbutton the clothes, loosen or take off the clothes If the clothes are wet with sweat, they should be replaced to cool down, the head can be covered with a cold towel, available, alcohol, white wine, ice water or cold water for the whole body bath and then blow with a fan or electric fan to accelerate heat dissipation. 2, cooling the patient’s head can be covered with a cold towel, available 50% alcohol, white wine, ice water or cold water for the whole body bath, and then use the fan or electric fan blowing wind to accelerate heat dissipation. Cooling blankets can also be used to give cooling if available. But do not quickly lower the patient’s body temperature, when the body temperature drops to below 38 degrees Celsius, to stop all cold compresses and other strong cooling measures. 3, hydration Initially and mildly, when the patient is still conscious, some cool drinks can be given, and when hydrating, a small amount of salt or baking soda can be added. But must not rush to replenish a lot of water, otherwise, it will cause vomiting, abdominal pain, nausea and other symptoms. 4, to promote awakening Royale heatstroke patients who have lost consciousness, can finger pinch the human middle, Hegu and other points to wake up. If breathing stops, artificial respiration should be implemented immediately. 5.Transfer For patients with severe heat stroke, they must be sent to hospital immediately. When transporting the patient, use a stretcher to transport the patient, do not make the patient walk, and pay attention to the transport, as far as possible, use ice bags on the patient’s forehead, back of the pillow, chest, elbow fossa and the root of the thigh, and actively carry out physical cooling to protect the brain, heart and lungs and other important organs. Fourth, heatstroke four taboos: 1, excessive drinking water: heatstroke must be supplemented with a large amount of water and salt, but excessive drinking hot water will be more sweaty, but cause further loss of water and salt in the body a large number of serious will cause a stroke phenomenon. This is more than worth the loss. The correct method should be a small number of times, each drink of water to not more than 300 ml is appropriate. 2, over-eating: can not eat greasy fishy food, too much to eat will increase the burden on the digestive system, so that a large amount of blood stagnation in the gastrointestinal, and the blood delivered to the brain will be relatively reduced, nutrients can not be fully absorbed, so should try to eat more light and refreshing things to adapt to the summer digestive capacity. 3, partial food chili: summer Yang floating outside, yin liquid deficiency, and spicy and dry food will only help heat but Yang, and it also makes your beautiful skin pop up a few not small bumps. Thus, eat less, of course, do not eat is better. 4, cold food injury: when the body is thirsty, cold drinks and melons and fruits food let people love, but unfortunately, after heatstroke these two things can not eat more, cool food will damage your spleen Yang.
