Cautery is a medical procedure that uses heat or chemicals to destroy tissue. It is often employed to stop bleeding, remove abnormal growths, or treat certain skin conditions. The process can be performed using various tools, including electric devices or heated metal instruments, and is commonly used in surgeries and dermatological treatments. There are two main types of cautery: electrocautery, which uses electrical currents, and chemical cautery, which involves applying caustic substances. Both methods aim to minimize blood loss and promote healing by sealing blood vessels and preventing infection. Cautery is a valuable technique in modern medicine.
