thermocautery

Thermocautery is a medical procedure that uses heat to destroy, remove, or stop bleeding from tissue. This is typically achieved by applying a heated probe or electrode to the affected area. The heat causes coagulation of proteins and blood vessels, leading to the destruction of the tissue or the sealing of damaged blood vessels.

The technique can be employed in various medical specialties, including dermatology, ophthalmology, and surgery. In dermatology, it might be used to remove small skin lesions, warts, or moles. In ophthalmology, it can be used to treat certain retinal conditions. Surgically, thermocautery is often used to control minor bleeding during procedures, ensuring a clearer surgical field and reducing blood loss.

There are different forms of thermocautery. Electrocautery, a common type, uses an electric current to generate heat. This can be monopolar, where current flows from an electrode through the patient to a grounding pad, or bipolar, where current flows between two electrodes on the same instrument. Other methods involve heated probes or lasers.

The procedure is generally performed under local anesthesia to minimize discomfort. Potential risks include pain, infection, scarring, and damage to surrounding healthy tissue if not performed with precision. The specific application and technique depend on the area being treated and the desired outcome. Post-procedure care usually involves keeping the treated area clean and dry to promote healing.
