Problems related to elastic stockings

       Recently there are constantly print media and stereoscopic media to ask some things about elastic stockings, combined with the usual also have many patients and even colleagues to inquire how to choose elastic stockings, I will talk about a few views on how to correctly choose elastic stockings: One, what is called elastic stockings?  Medical elastic stockings, that is, medical sequential decompression elastic stockings, through the different pressure gradient from the ankle to the thigh to promote the lower limb venous blood flow back to the heart function of the product, for varicose veins and the prevention and treatment of sequelae. It is an important and indispensable aid in the treatment of varicose veins. They are also used for the prevention and treatment of deep vein thrombosis in the lower limbs. Not all socks with elasticity are called medical elastic socks, but medical elastic socks are medical devices, and the batch numbers can be found on the webpage of the State Food and Drug Administration.  If you can’t find the batch number on the website of the State Food and Drug Administration, they are not medical elastic socks and the quality of the product is not guaranteed. Can not listen to the network or television advertising so-called thin leg socks. Zhu Yuefeng, Department of General Surgery, Run Run Run Shaw Hospital, Zhejiang University School of Medicine Second, who needs to wear elastic stockings?  Not everyone needs to wear elastic stockings, which have the function of promoting venous reflux, but without the indication of wearing not only can not get good benefit, but even may bring harm.  Applicable people: 1, doctors, nurses, teachers, traffic police, salesmen and other occupational groups who need to stand for a long time; 2, clerks, professional drivers, white-collar workers, frequent air travel and other occupational groups who need to sit and stand for a long time; 3, pregnant women, overly obese patients with increased abdominal pressure resulting in increased venous pressure in the lower limbs; 4, patients with major surgery, malignant tumor patients, hemiplegic patients who are bedridden for a long time and other deep vein Thrombosis high-risk groups.  Why should we wear elastic stockings? What is the working principle of elastic stockings?  The main working principle of elastic stockings is: 1. To curb pathological venous hypertension, to reduce the increase of venous pressure by external pressure, and to reduce the diameter of the overexpanded lower limb veins. With the pressure support of the elastic stockings, the function of the venous valves improves, reducing the risk of thrombosis or embolism by reducing the stagnation of blood in the lower extremities; 2. To alleviate the extent of the state of pathological blood stasis, which is useful for the prevention and treatment of eczema and ulcers caused by stagnant venous return in the lower extremities; 3. To promote the reabsorption of water from edematous tissues and relieve the pressure of lymphatic return; 4. Not to block the blood supply from the arteries. Therefore, unqualified compression stockings may not provide the right pressure gradient to promote venous return, but may reduce or block the blood supply from the arteries of the lower limbs, with serious consequences.  What are the pressure gradations of compression stockings and the corresponding indications?  According to the different pressure generated by the compression stockings, they are classified into pressure level 1-4, and pressure level 1 (18-21mmHg) and pressure level 2 (22-32mmHg) are usually used, of which pressure level 1 is used for the prevention of high level people, which can reduce the heaviness of the legs, relieve the degree of edema and reduce the risk of deep vein thrombosis. Pressure level 2 is used for the treatment of simple varicose veins, including conditions such as varicose veins in pregnancy combined with edema. Pressure level 3 is used for post-thrombotic syndrome, calf ulcers, severe deep vein valve insufficiency, lymphatic reflux disorders and other conditions.  V. Who can’t wear elastic stockings?  As with any treatment, compression stockings have their indications and contraindications.  The most important ones are: 1. Patients with atherosclerotic occlusive disease of the lower extremities, the use of elastic stockings may aggravate the ischemic symptoms of the lower extremities, which may lead to ischemic necrosis of the limbs.  2.Acute inflammatory period of skin or active period of ulcer.  3.Doctors diagnose other diseases that are not suitable for the use of elastic stockings.  VI. How to buy elastic stockings?  Unlike buying clothes, buying the right compression stockings needs to be done under the guidance of a doctor, who should measure the ankle diameter, maximum calf diameter, leg length and other physiological indicators before buying. You should not buy them at your own discretion, as they may lead to unexpected complications. You can buy them from pharmacies, medical equipment stores, and Taobao.  Before purchasing, you need to get the batch number of the FDA on the package of the compression stockings and verify it on the website of the State Food and Drug Administration. Do not buy elastic stockings without a lot number. It is not possible to give you the quality assurance of the treatment effect, and it is not possible to ensure the safety.  How to put on the stockings?  Many patients complain that it is very hard to put on the stockings and even give up wearing them. In fact, there is a technique to put on elastic stockings. First, fold the stockings back to the ankle, then put on the foot, and then stretch the folded part of the stockings towards the calf to finish putting them on. Some elastic socks have matching foot cover, you can put on the foot cover first, and then put on the socks, it will be much smoother.  Do I need to wear elastic socks all day long?  The answer is no. In principle, elastic stockings should be worn only during the day when your legs are exposed to standing body odor, that is, you need to take them off at night when you sleep flat. 24 hours of wearing elastic stockings is not good for your skin. The simple memory is: elastic socks are also socks, just like ordinary socks, which are worn in the morning when you get up and taken off at night when you sleep.  Nine, can healthy people wear elastic socks to slim their legs?  The answer is no, although elastic stockings can promote the return of blood and lymphatic fluid in the veins of the legs, and the fluid retention between the tissues is less, so it looks like the calves are thinner. However, if you observe carefully, the thickness of your calves will slowly return to the original after you take off the stockings for a short time. This is because elastic stockings cannot reduce the volume of the calf tissue. They can’t burn fat and other magical functions. So don’t expect to lose weight and slim your legs through elastic stockings.
