Chatting with old classmates who have become quite famous about the increasing number of patients with lower limb thrombosis and pulmonary embolism in their hospitals is actually a result of the improvement of medical standards, but the reason for the high incidence of thrombosis is in the details of patient care, and there is also a lack of medical knowledge of the country’s people. An action to talk about, one more person to understand, there must be someone less dangerous. Doctors understand simple, readers read and understand but also not easy to know the reason why it is more important to know the reason why, so to understand the problem from the human body’s muscle pumps to say. See the human body has a second heart? The calf is the second heart of the human body, unique and developed calf muscle group is very good to support the human upright walking. The muscles and the valves in the superficial and deep veins that accompany them form a complex and effective mechanical structure, and the contraction of the muscles when walking makes a large amount of accumulated blood in the lower limbs squeeze to the heart, playing a pump function, which doctors like to call the muscle pump. Pulmonary Embolism – A Horrible Killer for Both Doctors and Patients Pulmonary embolism is a clinically critical condition that has an elegant but hideous name – Slience Killer. In the global statistics of deaths from diseases, tumor is the first, heart attack is the second, and pulmonary embolism is the third, and the truth is so cruel. I like to compare the heart to an engine, and the pulmonary artery is the fragile link in the pipeline of the cardiopulmonary circulation. As shown in the picture above, once it is blocked by a foreign body, there is no air and blood mixing, and the engine immediately stalls, which is a danger that is self-evident. Thanks to medical advances, the mortality rate for patients treated immediately can be reduced from 25% before treatment to about 5%. But the doctor’s vocation will not be satisfied with this, we want to reduce it further, what to do? Causes of thrombosis Vascular specialists are aware of the classic three factors of thrombosis – hypercoagulability, slow blood flow, and vascular injury. I have seen all kinds of strange thrombosis triggers in the clinic, such as playing mahjong all day, taking the train for a few days, lying on the road all night after drunkenness, varicose veins bloodletting treatment, acupuncture and massage, playing computer with legs crossed, judo masters accidentally sprained ankles and so on, all of which can be categorized into the three major factors. Clinical obstetrics and gynecology, orthopedic surgery patients, obese people, tumor patients and some elderly bedridden patients also belong to the high-risk group. Sources of Pulmonary Embolism Emboli More than 90% of pulmonary emboli originate in the lower legs. Accelerating blood flow is the simplest, most direct and effective way to reduce the occurrence of blood clots. I think I have been urging my patients to exercise four times a day and demonstrating hand over hand (should be hand over foot) in order to prevent the possibility of blood clots in bedridden or postoperative patients just to reduce the likelihood of blood clots occurring. For healthy people exercise is easy and walking directly on the ground is not difficult. However, patients who are not able to walk on the ground and have movement disorders, such as pregnant women, obese people, hemiplegic people, and all kinds of postoperative patients, how to exercise in the hospital bed? Don’t worry, Dr. Smile offers you the simplest and most effective way – ankle flexion and extension exercises. If you are a doctor or nurse, encounter people with high thrombotic factors, especially the presence of dehydration or postoperative patients, do not just tell early down to the ground, more exercise, this is not enough, tell him (her) more explicit exercise guidance way. If you are a gynecologist, be sure to tell the new mother to move her calves and stomach, even if you have to demonstrate it by hand, maybe you will not let a child lose its mother. If you are a pregnant woman, the process of gestating life, no matter cesarean section or normal delivery, must do this action, if the old man told you to bed rest and recuperate sitting in the moon, bravely say no, health largely by your own mastery. If you feel too little space in any narrow transportation, don’t worry, calf belly move, maybe invisible you have been lucky to avoid the silent killer. If you are struggling in a life of drinking and drunkenness, you should also pay attention to the elegance of the posture when lying down, do not press their limbs, irregular life is hurting you, but must not hurt your body again. Without health, everything is zero.
