Editing Nosebleed (section)

=== Chemical cauterization ===
This method involves applying a chemical such as [[silver nitrate]] to the nasal mucosa, which burns and seals off the bleeding.<ref name=":1" /> Eventually the nasal tissue to which the chemical is applied will undergo [[necrosis]].<ref name=":1" /> This form of treatment is best for mild bleeds, especially in children, that are clearly visible.<ref name=":1" /> A topical anesthetic (such as [[lidocaine]]) is usually applied prior to cauterization. Silver nitrate can cause blackening of the skin due to silver sulfide deposit, though this will fade with time.<ref>{{Cite journal |last1=Béquignon |first1=E. |last2=Teissier |first2=N. |last3=Gauthier |first3=A. |last4=Brugel |first4=L. |last5=Kermadec |first5=H.
