Manager Wang is the head of a construction company, due to the relationship between work he usually socialize a lot. A chance opportunity, a friend invited him to do foot health massage. It just so happens that Mr. Wang felt that in recent days the calves are more sore and swollen, but also a little swollen. He recently worked more, this is a good opportunity to rest, regulation, will gladly go. Before the massage, the service staff was very enthusiastic for the manager to wash his feet, foot care, so he felt very comfortable, fatigue subsided. The attendant chatted with him while doing massage for him. At the beginning of the manager felt very relaxed legs, but unconsciously, he suddenly had difficulty breathing, shortness of breath, chest tightness, followed by a violent cough. The attendant was shocked and didn’t know what to do. Seeing that Manager Wang coughing more and more powerful, and even coughing up blood, the massage store manager realized the critical state of affairs and rushed him to the hospital. After the diagnosis, the manager is suffering from pulmonary embolism, by a variety of emergency rescue measures, finally relieved. The doctor said it was lucky to send in time, otherwise it could be life-threatening. ”Doctor, can you tell what exactly is the pulmonary embolism? Is it a pulmonary embolism caused by foot massage?” Manager Wang’s friend asked the doctor. ”Pulmonary embolism is also called pulmonary infarction, and its main cause is that the blood supply to the lungs is suddenly reduced because the pulmonary artery supplying blood to the lungs is blocked by thrombus. In this case, the oxygenated blood to the lungs is drastically reduced, which can easily cause shock; the thrombus blocking the pulmonary artery can produce acute pulmonary hypertension, which can cause right ventricular dilatation and acute right heart failure; the ischemia of the lung itself can also cause destruction of the alveolar wall and produce exudate, which in turn further affects the lung function. Patients will suddenly appear dyspnea, chest tightness and choking sensation, followed by severe cough, hemoptysis, or large amounts of foamy blood sputum, pleural tingling when the lesion involves the pleura, severe cases of cold sweat, cold extremities, a sharp drop in blood pressure, and even shock, can be accompanied by fainting and urinary and fecal incontinence, tachycardia, or cardiac arrest or ventricular fibrillation and life-threatening. In fact, foot massage itself can not cause pulmonary embolism, but the patient himself suffers from certain diseases, such as the veins of the lower extremities already have a thrombus in existence, easy to massage when the thrombus in the deep veins of the lower extremities are squeezed and with the venous return blood directly into the pulmonary artery, leading to serious consequences. According to statistics, pulmonary embolism caused by thrombosis of the veins of the lower extremities sources account for more than 90%, therefore, this situation should not receive foot massage. Manager Wang may have existed in the calf of the vein thrombosis, but not after the examination and diagnosis, foot and calf massage squeezed the vein thrombosis inside the calf loose, ran into the pulmonary artery, which led to the symptoms just now,” the doctor explained. At this point, the massage center manager was finally relieved. He admitted to the doctor that his staff, although trained in massage, but not all medical professional background, and has not encountered this situation before. The doctor reminded him that in the future, before doing foot massage for customers should pay attention to understand the customer’s medical history, and do not blindly massage patients with lower limb thrombosis. ”Then how to determine whether the customer has a lower extremity thrombosis?” The massage center manager asked. ”For some lower limb swollen people, in the case of failure to carefully check the deep veins with thrombosis, should learn in detail whether the patient has similar thrombosis in the past, and exclude deep vein thrombosis before foot massage operation. If the patient is informed that he/she is suffering from the above-mentioned diseases, he/she should be advised to actively treat and heal before receiving podiatry.” ”Then what issues should be noted when doing foot massage for such patients?” ”For patients clearly suffering from deep vein thrombosis of the lower extremities, do not carry out foot massage; for people with fractures of the lower extremities and often bedridden, attention should be paid to mastering the operation technique, be light and short, and pay attention not to do squeezing of the calf belly, so as not to cause hidden vein emboli to fall off with the blood flow to the lungs, thus causing pulmonary embolism. Similarly, for certain chronic patients, such as liver, kidney decompensation, cardiovascular and cerebrovascular disease, long-term diabetes and other people, in doing foot massage must be cautiously engaged.” The doctor then told the people present, “foot reflexology itself is a health care method, but also common diseases, chronic diseases, complementary therapies, practice has proved that it has to promote systemic blood circulation, improve microcirculation, reflex regulation of the whole body organs, the function of some chronic organic diseases also have auxiliary treatment and rehabilitation effect. But this is a very high demand for massage personnel, so it must be formal training to do. The choice of massage institutions should also be those who are formal, have a certificate of qualification to practice.”
