Induction of adrenergic beta-receptor blockade to attenuate the pressor response during intubation can lead to severe cardiovascular collapse and cardiac arrest.
Alerts to collapse risk with pre-intubation beta-blockade; case report leaves generalizability and frequency open.
Summary Adrenergic beta‐receptor blockade was induced to attenuate the pressor response to laryngoscopy and tracheal intubation; the patient subsequently suffered cardiovascular collapse culminating in cardiac arrest. The rationale of the technique is discussed.
