People traveling abroad by plane, sitting in a narrow space for a long time, lack of activity, be careful that venous blood return is blocked, causing a life-threatening crisis! The medical official name of "economy class syndrome" is deep vein thrombosis, also known as "cabin syndrome" and "travel syndrome". Traveling by means of transportation for a long time increases the blood viscosity, leading to poor blood return, leading to tiny thrombosis in venous blood vessels, which gradually spreads from the thigh to the heart and lungs. Once standing up, blood clots reach the lungs, causing dyspnea and chest pain, and even collapse or even sudden death in severe cases. The high-risk group of deep vein thrombosis should not be careless. The Department of Disease Control and Prevention of the Ministry of Health said that deep venous thrombosis is more likely to occur in lower limbs, especially in the lower legs. If the thrombus is large, it will affect the blood supply, even cause blood vessel obstruction, and there will be local redness, swelling and pain. The occurrence of deep venous thrombosis is divided into the following three risk levels. 1. high risk: it is easy to form embolic constitution, such as patients with hereditary coagulation abnormality, cancer, patients undergoing major surgery within 6 weeks, such as brain surgery, cardiac surgery, plastic surgery, obstetrics and gynecology, urology surgery, etc. 2. Moderate risk: patients with deep vein thrombosis, pulmonary embolism or family history, pregnancy or recent delivery, oral contraceptives or other hormonal drugs, patients with serious health conditions such as congestive heart failure and inflammatory bowel disease, and those who have suffered severe trauma recently, especially those with abdominal cavity, pelvic cavity and lower limbs injuries, have obesity body mass index >; 30 or height > 190 cm, middle-aged and over 40 years old. 3. Low risk: those without the above high risk factors. Six simple ways to prevent economy class syndrome: healthy exercise and lifesaving to prevent deep vein thrombosis.
