How to prevent heatstroke in hot weather?

Early symptoms of heatstroke (sweating, trance) should be evacuated from the high temperature scene in time. Avoid strong physical labor under the conditions of high temperature and poor ventilation, avoid wearing airtight clothes, eat more salty drinks, and constantly replenish water and electrolyte loss. When high temperature operation is inevitable, it is necessary to improve working conditions, strengthen protective measures, and replenish lost water and salt as much as possible. People who are prone to illness should avoid working at high temperature.

Heatstroke is most likely to occur in the elderly, children, pregnant women or people with basic diseases (such as cardiovascular and cerebrovascular diseases and obesity).

1, the physical function of the elderly declines, the cardiac output can not be adjusted in high temperature environment, and the circulatory disorder leads to heatstroke.

2, children are mostly heatstroke caused by poor sweating reaction ability.

3. People with low blood potassium due to diarrhea caused by cold, fever and gastroenteritis are also prone to heatstroke.

Coping methods:

1, cooling in vitro

Designed to rapidly reduce deep body temperature. Take off the patient's clothes, blow cool air and spray cold water or wrap the whole body with cold wet sheets. Ice water immersion is no longer recommended, because there will be many complications such as hypotension and chills. However, if other methods cannot cool down, this method can also be considered, but at this time, it is necessary to monitor the deep body temperature. Once it is lower than 38.5℃, it is necessary to stop using ice water to cool down to prevent hypothermia.

2, cooling in the body

If in vitro cooling fails, you can also use iced saline to wash your stomach or rectum, peritoneal lavage with sterile normal saline or hemodialysis, or transfuse autologous blood after cooling in vitro.

3. Drug cooling

Chlorpromazine has the functions of regulating body temperature center, dilating blood vessels, relaxing muscles and reducing oxygen consumption. Patients with chills can be given chlorpromazine intravenously and their blood pressure can be monitored at the same time.

4. Symptomatic treatment

Coma patients are prone to lung infection and pressure ulcers, and need to strengthen nursing; Provide necessary heat and nutrition, promote the recovery of patients, keep the respiratory tract open and provide oxygen; Actively correct the disorder of water and electrolyte and maintain acid-base balance; The rehydration speed should not be too fast, so as not to promote heart failure, and quick-acting digitalis preparation should be given when heart failure occurs.

Use pressor to correct shock; Mannitol dehydration to prevent and treat brain edema. Hormone has a certain effect on the treatment of pulmonary edema and brain edema, but it is easy to be complicated with infection when the dose is too large. Corresponding treatment measures should be taken for various complications. Baidu encyclopedia-heatstroke
