Pulmonary Edema following Phenylephrine Intranasal Spray Administration during the Induction of General Anesthesia in a Child

Abstract

Topical phenylephrine, an agent used to facilitate nasotracheal intubation and prevent nasal mucosal bleeding, can cause severe hypertension in some patients, secondary to its stimulation of alpha-adrenergic receptors. Moreover, a high incidence of pulmonary edema is found in patients whose phenylephrine administration is followed by treatment with beta-blocking agents. We report a case of acute pulmonary edema in a pediatric patient who developed severe hypertension after the inadvertent administration of a large dose of topical nasal phenylephrine, followed by beta-adrenergic antagonists (esmolol).
