Radiation isotope dressing treatment principle Radiation isotope dressing treatment is the use of nuclide hair body beta ray, so that the local lesions produce radiation biological effect and achieve the purpose of treatment, no effect on the surrounding normal tissues and the whole body, generally no scar after healing, currently there are two types of dressing device, one is the nuclide manufacturer to provide commercial dressing device, a metal product, has a certain shape and size, mostly using According to the shape of the lesion, the dressing is applied directly under the premise of protecting the surrounding normal skin, and the treatment can be done in one large dose or several small doses; the other one is temporarily prepared into a kind of dressing tablet by the using unit, mostly using the radionuclide phosphorus-32, which is usually prepared into a certain radioactive concentration with phosphorus-32 bath, and then made into a dressing device of corresponding size according to the various shapes of the lesion with high-quality filter paper as the support. It is usually prepared with a certain radioactive concentration of phosphorus-32 bath solution, and then made into a corresponding size of dressing device according to the various shapes of lesions, and directly applied to the lesions, and the time of one dressing is decided according to age and disease. Generally, the second treatment is done after an interval of 3 to 5 months. Both methods have good effect on pediatric skin hemangioma. According to statistics, the efficiency of treatment for simple hemangioma and bright red nevus is 98.3% and 88.2% respectively. The advantages of skin hemangioma dressing treatment are complete treatment and no scarring. The method is simple, economical, painless and itch-free.
