Cardiopulmonary Arrest due to Misuse of Viscous Lidocaine

Arch Otolaryngol. 1985;111(11):768-769. doi:10.1001/archotol.1985.00800130100015

• A 30-month-old female infant had a cardiopulmonary arrest due to viscous lidocaine. The protective airway mechanisms were blunted by this drug, resulting in aspiration, hypoxia, seizures, and death. Lidocaine has also been associated with respiratory depression, psychosis, methemoglobinemia, and toxic cardiovascular reactions. We do not recommend the use of viscous lidocaine for minor oral irritation in infants and young children.
