  • The medical practice or technique of cauterization is the burning of part of a body to remove or close off a part of it in a process called cautery, which destroys some tissue, in an attempt to mitigate damage, remove an undesired growth, or minimize other potential medical harmful possibilities such as infections, when antibiotics are not available. The practice was once widespread for treatment of wounds. Its utility before the advent of antibiotics was effective on several levels: To stop severe blood-loss and preventing exsanguination To close amputations Cautery was historically believed to prevent infection, but current research shows that cautery actually increases the risk for infection by causing more tissue damage and providing a more hospitable environment for bacterial growth. Actual cautery is a term referring to the metal device, generally heated to a dull red glow, that is applied to produce blisters, to stop bleeding of a blood vessel, and other similar purposes. The main forms of cauterization used today in the first world are electrocautery and chemical cautery—where both are, for example, prevalent in the removal of unsightly warts. Wikipedia
