Liquid nitrogen is extremely cold. It will freeze any living tissue it comes into contact with. Applying small amounts of liquid nitrogen to various skin problems is now a standard treatment. The medical term for this treatment is cryotherapy.
एक नजर में
Liquid nitrogen can be used to treat warts, verrucas, skin tags, and small skin growths.
The treatment usually lasts for 10-30 seconds and causes some discomfort.
After treatment, the treated area will discolour and fall off.
The surrounding skin may become red, swollen, or form a blister.
Most treated skin responds well, but some thicker warts may need more sessions.

What can I expect from liquid nitrogen treatment?
सामग्री पर वापस जाएंAfter a liquid nitrogen treatment, the lump, wart or whatever is being treated will gradually discolour and fall off.
The surrounding skin will sometimes become red and swollen and be sore for a day or so. It is similar to a mild burn.
Occasionally a blister (sometimes a 'blood blister') forms. If this happens, it is best to pop it with a clean pin and apply a plaster.
New skin quickly forms and any scab or blister will soon disappear. The appearance of the skin afterwards is usually good.
Does liquid nitrogen treatment always work?
सामग्री पर वापस जाएंUsually, it does. However, sometimes thicker warts or verrucas need two or more sessions of liquid nitrogen treatment over a period of a few weeks to get to the root.

PEG feeding tubes
Percutaneous endoscopic gastrostomy (PEG) feeding tubes are now being used more often than in the past. PEG feeding is used if you have problems with swallowing or if you cannot eat and drink enough. PEG is usually the recommended method of help with feeding if your bowel is working normally and you need long-term help with feeding.
