In summer, the weather is particularly hot. People do not pay attention to the heat stroke. Heat stroke is particularly troublesome. Therefore, the key to summer heat is to prevent heat stroke. How can we prevent heat stroke in the summer?
Dog days to prevent heat stroke has a coup
One is to escape the hot sun. From 10:00 to 16:00, avoid walking under the hot sun, because the possibility of heat stroke during this time period is 10 times that of normal time. Children, the elderly, pregnant women, people with chronic diseases, especially those with cardiovascular diseases, should try to reduce their chances of going out during the hot season.
Second, shading protection. If you are wearing parasols wearing a hat, sunglasses, sunscreen.
Third, it is to add water. Develop good drinking habits, drink less sweet drinks, and drink plenty of boiled water.
Fourth, strengthen nutrition. Usually can drink tomato soup, bean soup, soy milk, sour plum and so on.
Fifth, it is to ensure adequate sleep. Lack of sleep, people's resistance decreased, more likely to heat stroke.
When a person suffers from a heat shot, his clinical performance mainly includes two aspects. The first is the performance of heat stroke itself, that is, the "triple sign of heat stroke", including: fever - core body temperature greater than 40 °C (rectal temperature), no sweat - dry skin, flushing or pale skin, disturbance of consciousness or coma, often accompanied by convulsions or tonic attacks. The second is due to organ dysfunction caused by heatstroke or heat stroke, including multiple organ dysfunction (MODS) or failure (MOF), shock, heart failure, liver and kidney failure, rhabdomyolysis, and intestinal mucosa. Barrier destruction, gastrointestinal bleeding, intestinal failure, cerebral edema - intracranial hypertension and internal environment disorders, electrolyte imbalances.
Combining the causes of heat stroke and heat stroke (high temperature, high humidity, exercise) and clinical manifestations, diagnosis is generally not difficult. The most critical link is prevention and diagnosis.
When there is heat stroke and heat stroke, the treatment principle highlights the word “rescueâ€. In the treatment concept, two factors must be seized: one is rapid cooling, and the other is multi-organ function support.
The treatment of heat stroke in hospitals is understood as a highly-difficult, high-intensity, comprehensive rescue procedure with the aim of reducing mortality and disability. A very important part of treatment is rapid cooling. The goal is to reduce the core body temperature (usually based on the rectal temperature) to 38.5°C or lower within 2-3 hours to block the "inflammatory cascade reaction" initiated by thermal injury. There is a lot of information that has confirmed that the mortality rate of heat stroke is closely related to high fever and duration. People with high fever and heat stroke performance greater than 3 hours often have significantly increased risk. Therefore, 3 hours after the onset of illness is the "golden time period" for the treatment of heat stroke and heat stroke. In other words, if a patient with heat stroke or heat stroke is found, it should be sent to the hospital immediately for treatment.
In the case of heat stroke and heat stroke, commonly used cooling methods include three aspects. First, in vitro cooling, which everyone can do, but for patients is the quickest, most important and most effective method of cooling: take off Patient clothes, blow cold wind and spray cold water or wrapped in cold and wet sheets. In the past there were methods of using cold water spray or soaking, but because of the frequent occurrence of hypotension and chills and even accidents, these methods are no longer recommended. Arrived at the hospital, doctors can also use the body cooling and drug cooling. That is, when the in vitro cooling is ineffective, gastric or rectal lavage with iced saline can also be performed with sterile saline for peritoneal lavage, or the autologous blood can be cooled and returned to the body after cooling. Drug cooling refers to the use of drugs that can regulate the functions of body temperature centers (such as chlorpromazine). These drugs often have the effects of expanding blood vessels, relaxing muscles, and reducing oxygen consumption. They are clinically recommended for routine use, especially in combination with convulsions. patient.
The mortality rate of severe heat stroke and heat stroke is high, and the degree and duration of body temperature increase are directly related to the mortality rate. Factors that affect prognosis are mainly related to the degree of damage to the nervous system, liver, kidney, and muscle, and blood lactate concentration. Coma more than 6 hours or DIC has a poor prognosis, but also patients can also leave brain dysfunction. In view of this, in the daily life and work, the protection against heat stroke and heat stroke is particularly important. When the work under high temperature cannot be avoided, labor conditions need to be improved, labor protection measures must be taken, and the missing water and salt should be added as much as possible. Anyone who has a tendency to be vulnerable to frailty in the elderly should avoid working under high temperatures. For early symptoms of high-temperature operators, timely evacuation of high-temperature scene, to avoid high temperatures, poor ventilation and strong physical labor, to avoid wearing gas-permeable clothing, eating salty drinks to continuously supplement the loss of water and electrolytes.
In short, when summer heat waves strike, people learn about heat stroke and heat stroke, know how to avoid and protect, and further popularize the knowledge of emergency first aid in the crowd, reduce the occurrence of heat stroke and heat stroke, and reduce the mortality of critically ill patients. Particularly important.
Compacted Vacuum Suction Unit
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
