The liquid nitrogen cryotherapy is a physical therapy commonly used in dermatology and beauty salons of hospitals, and aims to achieve the purpose of treating and beautifying by applying liquid nitrogen to generate deep low temperature which acts on local tissues to cause a series of physicochemical changes to cause tissue cell degeneration and necrosis. Liquid nitrogen cryotherapy is widely applied to clinical departments of hospitals, and is mainly used for treatment in skin cosmetology departments: warts, freckles, black nevi, pigmented spots, etc., which are excrescences that hinder the skin from being beautified. The refrigerant liquid nitrogen is liquid nitrogen, colorless, odorless, non-corrosive and non-combustible, and has a temperature of-196 ℃.
Liquid nitrogen is commonly used in dermatology by cotton swab contact and copper tip contact. The cotton swab method comprises soaking cotton swab in liquid nitrogen, and applying the tip or tip soaked with liquid nitrogen to the affected part under slight pressure. Can be used for treating superficial skin diseases. The copper head method is that copper freezing heads with different shapes and sizes are connected to liquid nitrogen freezing therapeutic apparatus according to the pathological changes and sizes and are directly placed on the pathological change part and slightly pressurized when treating.
When the cotton swab contact method is used for treating the disfigurement diseases, the control of the dosage, the time, the pressure strength and the pressure depth is very important. The freezing dose for protecting healthy tissues, especially face, neck, finger and toe, should be strictly controlled and should not be too deep to damage the underlying tissues, tendons or phalanges due to excessive freezing. These are not easily and accurately grasped by the operator's skill and subjective control.
The depth varies and the consequences vary:
degree I freezing (superficial position, on epidermis, local part after operation shows mild flush, no water scar, skin damage after one week with desquamated epidermis, no sequela on local part)
Freezing at II degree (the position is deep to the dermis, scar appears locally after operation, skin lesion about two weeks is removed along with the fallen epidermis, diffuse pigmentation can appear after operation, and the normal can be recovered about half a year)
