Is a sprained ankle also life-threatening? It’s not common, but be careful


1. The fatal sprain is not sensational.

A sprained ankle can be life-threatening, and while it doesn’t happen often, it must be prevented. Hua Zi gave two examples to his friends. The first example was a young female reporter who sprained her ankle. She recorded her circle of friends and described symptoms such as no pain, pain extending from the sprained ankle to the calf, and paralysis of the toes. , died suddenly 12 days later due to pulmonary embolism滴雞精功效.

The second example is an orthopaedic surgeon known to Hua Zi. During his college internship, he followed a teacher to help a 30-day-old patient with a sprained ankle to remove a cast. During the removal of the cast, the patient suddenly experienced dyspnea and chest pain. In the end, he was not saved. The cause was also a sudden pulmonary embolism.

Second, lower extremity venous thrombosis and pulmonary embolism.

Blood in human blood vessels has two mechanisms: blood clotting and thrombus breakdown. Blood clotting prevents blood from leaking from the wound, and thrombus breakdown prevents thrombosis and blockage in blood vessels. Usually, the two mechanisms are in equilibrium. However, when the limbs are immobilized for a long time, the blood coagulation mechanism prevails, and venous thrombosis is particularly prone to occur in the lower extremities.

If a venous thrombosis breaks off, it will flow through the inferior vena cava into the right atrium and then pump from the right ventricle into the pulmonary artery. If the thrombus is large, it can block the arteries in the lungs, causing a pulmonary embolism, preventing blood from entering the lungs for gas exchange.

10% of patients died within hours of symptoms such as dyspnea, chest pain, hemoptysis, tachycardia, syncope, etc.

Third, resting is not completely motionless.

Lower extremity venous thrombosis and prolonged immobilization of the lower extremities are common factors. For example, trauma, surgery, and disease result in limited mobility of the lower extremities. Prolonged bed rest may lead to venous thrombosis. There are also long trips, long rides on trains, planes and other means of transportation. They cannot move their feet due to their narrow seating and may also induce venous thrombosis滴雞精功效.

So if there is an illness that requires rest, that doesn’t mean staying completely still. For example, with a sprained ankle, the main purpose of resting is to prevent the ankle from carrying weight, but the toes should be moved regularly. Every 2-3 hours, hook your toes firmly, then relax. Repeated 20 times can effectively prevent lower extremity venous thrombosis.

When traveling by plane, train and other means of transportation for a long time or sitting in the office for a long time, you should also pay attention to the prevention of lower extremity veins. After sitting still for an hour, the risk of venous thrombosis increases by 10%. After 90 minutes of sitting still, blood circulation to the knee joint will decrease by 50%.

So when you’re sitting for long periods of time, it’s a good idea to get up and walk for a few minutes every 45 minutes. If walking is inconvenient, you can do the above hook-toe action, or stand on tiptoe and tap your calf to rotate your feet in and out, which can also promote blood flow and prevent venous thrombosis in the lower extremities.
