cautery

I am not really good when it comes to medical terms so I search more online for details. Cautery is an agent or instrument used to destroy tissue by burning, searing, cutting, or scarring, including caustic substances, electric currents, and lasers and it is the use of heat, electricity or chemicals to destroy tissue. 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. Cauterization was used to stop heavy bleeding, especially during amputations.
