    Author: Slaughter MS, Gordon PJ, Roberts JC, Pappas PS.
    Journal: Ann Thorac Surg; 1999 Jun; 67(6):1776-8. PubMed ID: 10391291.
    Abstract:
    Hypoxemia during bronchoscopy occurs frequently. It can usually be managed by supplemental oxygen and bronchodilators or, in some cases, occasionally stopping the procedure. Benzocaine spray is commonly used as a topical anesthetic agent during bronchoscopy. However, it has been associated with the development of methemoglobinemia. The following is a case report of hypoxia during bronchoscopy from benzocaine-induced methemoglobinemia and its management.
