Silver nitrate sticks are often used for minor hemostasis where patients are not under general anesthesia, and where electrocautery would be painful and inconvenient. One common use of silver nitrate sticks is in Emergency Medicine, to control epistaxis (nosebleed). The stick is rolled on the affected mucous membrane or visible blood vessel in the nares (nostril) where the chemical cauterization stops the minor bleeding.
