Historical use of silver nitrate for the management of epistaxis - evidence-based practice?
Objective:
Epistaxis is one of the most common emergencies presenting to the ENT service, and silver nitrate cautery is the mainstay of epistaxis treatment in most centres worldwide. This review aimed to ascertain the historical evidence behind current common practice.
Method:
A review was conducted of historical published literature pertaining to epistaxis management.
Results:
Silver in medicine dates back to 4000 BC, with silver nitrate first being used in 69 BC. Modern medical use for epistaxis is documented in case reports over the last 200 years.
Conclusion:
The precise origin and evidence-based practice of using silver nitrate for epistaxis is not well-established or understood. The mechanism of action is questionable; novel research of silver nitrate for this common ENT emergency presentation may be required.
