Since 2500 BC it is known that cold has anti-inflammatory and analgesic effects to the wound. Modern technologies allow to obtain much lower temperatures than were assured by wrapping with snow or ice.
Cold treatment – cryotherapy
Everyone knows, from personal experience, that cold relieves pain, reduces swelling and bleeding.
An additional advantage is that this action does not cause side effects and does not over-burden the cardiovascular system. Low temperatures, as a form of treatment, are used in both ad hoc and ambulatory treatment.
The cryosurgery devices that are most often used:
- Liquid nitrogen, which is a liquefied gas of a temperature of – 196.5°C
- Solid carbon dioxide (the so-called “dry ice”) of a temperature of – 78.9°C
- Nitrous oxide of a temperature of – 88.7°C
- Ethyl chloride
