- Caustic_pencil abstract "A caustic pencil (or silver nitrate stick) is a topical medication usually containing silver nitrate, used to chemically cauterize skin, providing hemostasis or permanently destroying unwanted tissue such as a wart, or mole. They are not used as a treatment for minor cuts. Not to be confused with a styptic pencil.The silver nitrate in caustic pencils is in a dried, solid form at the tip of a wooden stick, much like a long matchstick. When the silver nitrate is applied to a wound or lesion, the tissue moisture or blood dissolves the dried nitrate salt, which then chemically burns the tissue. It requires moisture for activation.Silver nitrate sticks are often used for minor hemostasis where patients are not under general anesthesia, where electrocautery would be painful and inconvenient. One common use of silver nitrate sticks is in Emergency Medicine, on patients presenting with epistaxis (nosebleed). The silver nitrate stick is rolled on the affected mucous membrane or visible blood vessel in the nares (nostril) where the chemical cauterization stops the minor bleeding.If the bleeding is too significant, the chemical cautery may not be effective, as the flowing blood can wash away the chemical before it can react with the tissue. It can also be accidentally spread to undesirable locations where it can cause skin staining and tissue burns. This is especially important, as it is often used in the nose, where accidental aerosolization can occur, splattering the clinician or other parts of the patient and causing unintentional burns. Accidental application to unintended tissue is treated with copious water irrigation.".
