The 72-year-old Xie Bo is a folk music creator. He suffered from vascular disease of the foot two years ago. Before the Spring Festival, he started the life of soaking his feet after meals with the recommendation of a friend.
But I didn’t expect that, after soaking twice, Xie Bo noticed swelling and pain in his right ankle, the original healed scar began to swell, and a pustule half a finger long appeared.
Shepper’s ankle wound.
Aware that the situation was not right, Xie Bo dragged his sick foot to and from several hospitals to seek medical treatment.
“In the beginning, other hospitals prescribed some antibiotics, which were painful, ulcerated, and ineffective.” Finally, Xie Bo came to the Affiliated Traditional Chinese Medicine Hospital of Guangzhou Medical University, where he took traditional Chinese medicine for conditioning and externally applied the hospital’s homemade Shengji ointment. , After a month of treatment, the ankle wound finally healed and recovered.
Hospital self-made ointment.
Patients with lower extremity ischemia
It is forbidden to soak feet in hot water
Why Scheiber After foot soaking, there will be ulcers on the right lateral ankle that are difficult to heal? Li Shunning, deputy director of the Department of Vasculitis, explained that the ulcer at Xie Bo’s lateral malleolus is a type of chronic refractory ulcer.
“Schieber’s condition is complicated. He has a history of rheumatoid arthritis, rheumatic vasculitis, mild arteriosclerosis in the lower extremities, etc., which may lead to insufficient blood supply to local tissues.”
She said that because the scar tissue has poor blood supply, the tissue is more ischemic and hypoxic after foot soaking, and an ischemic refractory ulcer will occur. Just like the blockage of the roots and pipes that absorb and transport nutrients in plants, once water and nutrients are lacking, the plants will slowly wither and wither.
“Ulcers persist for a long time and develop in depth. Once the ulcer breaks through the subcutaneous tissue and ligaments, destroys the joint capsule of the ankle, and exposes the joint cavity, the consequences are irreversible and ultimately require amputation.”
< p> Therefore, she especially reminded that patients with lower extremity vascular disease should be cautious with foot soaking, and patients with lower extremity ischemia should not be allowed to soak their feet with superheated hot water.
Severe refractory sores may lead to amputation
It is reported that chronic refractory wounds is a broad term that clinically refers to the formation of various causes The ulcers have not healed after a long period of treatment (at least more than 1 month), and there is no healing tendency.
Chronic refractory ulcers are mostly caused by surgical incision, accidental trauma, ulceration of carbuncle, radiation injury, diabetes, lower extremity arterial insufficiency, lower extremity venous insufficiency, connective tissue disease, pressure ulcers and other diseases. It is a common disease and frequently-occurring disease. Because it does not heal for a long time, it forms intractable and refractory ulcers. If the disease is serious, it can affect the quality of life of patients. It is one of the clinical refractory diseases and a major problem in clinical wound repair. In particular, refractory sores related to blood vessels can lead to amputation in severe cases, which is characterized by a high disability rate.
Who is not suitable for foot bath?
It is often believed that foot soaking can improve ischemic symptoms, run blood gas, and the hotter the water, the better. Are high temperature foot baths really healthy?
Zhang Jinsheng, an attending physician in the Department of Vasculitis, has seen many patients with cold feet and severe gangrene due to improper foot soaking.
He said that high-temperature foot baths cannot dilate the blocked blood vessels.
“On the contrary, hot water at an excessively high temperature will only cause excessive expansion of the arterial blood vessels in the foot, while the occluded blood vessels will not be effectively expanded, and finally the ischemic tissue may form thieves due to the increased blood flow of normal tissue. The phenomenon of blood ischemia.”
In addition, medical research has shown that the increase in the temperature of the surrounding tissue can aggravate the local intravascular inflammatory response, increase the oxygen consumption of the ischemic tissue, aggravated ischemia.
“For patients who really need to soak their feet to improve their foot symptoms, it is recommended to consult a vascular specialist.”
