Glucagon for Adrenergic Refractory Anaphylactic Shockin Patients Taking Beta-Blockers During Coronary Angiography

Allergic reactions to iodine contrast agent rarely lead to anaphylactic shock affecting hemodynamics. We treated two cases of anaphylactic shock during coronary angiography, which did not respond to adrenaline because the patients had taken beta-blockers. Instead, glucagon relieved their conditions. If patients treated with beta-blockers experience anaphylactic shock during coronary angiography, we should consider glucagon as a treatment option because the persistence of shock refractory to adrenaline leads to unfavorable outcomes.
