What should I pay attention to during liquid nitrogen cryotherapy?

Modern medical technology is developing very rapidly. Almost every few years, some new treatment methods appear, providing accurate and thorough treatment methods for more and more difficult and complicated diseases. Among various new medical technologies, the use of liquid nitrogen to treat diseases is widely sought after because liquid nitrogen uses extremely low temperatures to kill malignant cells in tissues but has no effect on healthy cells. Although liquid nitrogen technology is very advanced, this treatment method invented using modern physics theories has certain risks. Let’s take a look at what we should pay attention to in liquid nitrogen cryotherapy?

Normal cells will suffer irreversible damage when they are in an extremely frozen state. It works by rapidly killing the cells in the diseased area in an extremely frozen state, allowing the diseased area to recover normally. It is generally used to treat warts, corns, verrucae, neurodermatitis and skin diseases.

Note :

1. After cryotherapy, the wound surface should be kept clean and dry, and should not be exposed to water within one week. Apply antibiotic ointment daily to prevent infection. Allow the scab to fall off naturally; do not scratch, tear, or scrub it with your hands.

2. After treatment, local tissue pain may occur, which will disappear on its own after 1-2 days. Painkillers can be taken if necessary.

3. If local tissues become swollen, have blisters or bullae after treatment, and there is too much blister fluid, you can use a sterile syringe to draw it out or puncture it, but do not tear off the blister wall. It is more obvious in areas with loose tissue, such as around the eye sockets or with tender skin.

4. If the lesion is not healed after one treatment and needs to be repeated, wait until the scab falls off by itself before repeating the treatment.

5. Generally, after cryotherapy, there is depigmentation in the center of the lesion and pigmentation around it. Especially after receiving cryotherapy on the face, you should pay attention to shading and sun protection to avoid aggravating local pigmentation.

6. If there are blood vessels or the frozen area is too deep, some patients may experience delayed edema, exudation, blood blisters, bleeding, chronic ulcers, hypertrophic scars, non-healing of the wound surface, etc., and active symptomatic treatment should be given early. Special attention should be paid when treating the face.

7. Some patients may experience local neurological dysfunction, such as skin numbness and pain, which generally recover gradually within 3-6 months.
