Before the holiday, "I Am a Great Doctor" invited Ye Zhidong, director of the Department of Cardiovascular Surgery of the China-Japan Friendship Hospital. We have prepared a set of safe travel strategies for everyone.
Some time ago, there was such a news related to holiday travel on the hot search, Guangzhou Daily reported on the evening of February 21: The reporter learned from a number of medical institutions that on the way back to work after the Spring Festival holiday, there were many patients who had acute pulmonary embolism because of a long time in the car, and the continuous driving time was 20 to 30 hours, and 3 people unfortunately died. Sudden death is not uncommon with holiday travel, and the main culprit of sudden death is the fatal pulmonary embolism caused by sitting for a long time during long-distance travel! The May Day holiday is coming soon, and experts give the most practical holiday travel health guide.
Be vigilant! Breaking your foot can cause a fatal blood clot!
Mr. Ye Zhidong, an expert, told us that there are two groups of people who are at high risk of fatal pulmonary embolism during long-distance travel. These two groups of people are those who have broken their feet and those who have tattoos on their legs.
What is the relationship between sudden death after a long-distance trip to the heel? The expert showed us a prop of a damaged blood vessel, when the foot is broken, it is easy to cause subcutaneous soft tissue damage, and the rupture of capillaries will lead to congestion. The lining of blood vessels may be rough and cracked. If the local blood vessels are subjected to strong external force, it may cause blood vessel damage, resulting in poor blood circulation, resulting in symptoms of local blood vessels. This is where the inner wall of the injured blood vessel can cause blood clots. Combined with prolonged sedentary travel, the risk of fatal thrombosis is greatly increased.
"Little earthworms" can cause "sudden death"
The second high-risk group is people with long leg lines, in this case people with varicose veins of the lower limbs. With normal venous vessels, blood flow flows from the lower back to the heart in such a route. There are healthy venous valves in the blood vessels. It is a one-way valve that prevents blood from falling from top to bottom, but in people with varicose veins, this "valve" has a problem, and the blood cannot flow back completely, and over time there is a thrombus in the blood vessels. Some surveys and studies have shown that patients with varicose veins of the lower limbs are 5.3 times more likely to have deep vein embolism than the general population, and the chance of pulmonary embolism is nearly twice as high! And varicose veins of the lower limbs is a high-incidence disease, and experts say that about 30 to 40 percent of the population in the country suffer from the problem of varicose veins of the lower limbs. We found that many staff members at the scene had varicose veins in the lower limbs.
Self-test of varicose veins of the lower limbs in the morning and evening
A simple way to find out if you're at risk of varicose veins in your lower limbs. Measure the circumference of your calves in the morning and evening. The difference in results is within 1 centimeter, which is generally normal. If the difference is more than 2 cm, there may be a problem with poor venous return. Varicose veins may have occurred. This is because after suffering from varicose veins, blood stagnates within the varicose veins. Slow blood flow leads to more arterial blood coming in and less venous blood coming back. As a result, the interstitial space of the tissues will stagnate, and the lower leg will swell.
Of course, there is a "gold standard" in the hospital to diagnose whether you have varicose veins of the lower limbs, which is the color ultrasound of the veins of the lower limbs. It takes 6 seconds to diagnose if you have varicose veins in your lower limbs.
One action to solve the health crisis in the long distance
To prevent the risk of sudden death from long-distance travel, two tips to help you travel safely. The first is to avoid sitting for long periods of time. Here experts recommend a particularly effective "micro-movement". You don't need to leave the seat to help the blood run to reduce the risk of thrombosis, the practice is also very simple, squeeze from bottom to top on the leg with your hand, expert Mr. Ye said, the position of the squeeze is focused on the calf position, not the front of the leg, this action can play a booster pump effect, help the venous blood in the calf run upward, reduce the risk of retention.
1 minute secret!
Putting on varicose vein socks is as simple as that
The second way to avoid pulmonary embolism is to wear varicose vein stockings, also known as gradient elastic stockings, which are characterized by a gradual decrease in pressure from the bottom up, which can combat the stagnation of venous blood in the lower extremities caused by gravity or venous lesions, and promote venous blood return. Many people feel that varicose vein socks are tight and difficult to wear, and we can wear varicose vein socks in just 1 minute.
Raise your legs for about 30 seconds to allow the blood to flow back in, then lay your legs flat and put on the compression stockings. Then roll the elastic stockings from the head to the toes, put them into both hands, stretch the palms of the hands, try to make the toes into the sock roll, and then use the thumb as a guide to gently pull up the elastic stockings, so that the heels, ankles, and calves reach the place where they should be, and smooth the elastic stockings close to the body after wearing. Pay attention to the blood circulation of the lower limbs, pay attention to whether the temperature of the skin is cool, whether the skin color is white, and the pulse of the dorsalis pedis artery.
The experts also showed us the changes in medical methods and the latest technology for the treatment of varicose veins of the lower limbs. The development of technology has made it possible to treat patients with varicose veins from major trauma to small minimally invasive surgery of less than 1 centimeter. Reduces the risk of fatal pulmonary embolism in patients.
