BRASH Syndrome Leading to Cardiac Arrest and Diffuse Anoxic Brain Injury: An Underdiagnosed Entity

BRASH (bradycardia, renal failure, atrioventricular [AV] nodal blocking medications, shock, hyperkalemia) syndrome describes the phenomenon of profound bradycardia from a combination of hyperkalemia and use of AV nodal blocking medication with underlying renal injury. We present a case of BRASH synd...

Sumario:BRASH (bradycardia, renal failure, atrioventricular [AV] nodal blocking medications, shock, hyperkalemia) syndrome describes the phenomenon of profound bradycardia from a combination of hyperkalemia and use of AV nodal blocking medication with underlying renal injury. We present a case of BRASH syndrome in a patient on chronic beta-blocker therapy for his coronary artery disease who presented with life-threatening hyperkalemia and acute renal failure. Due to failure in early recognition and superimposed effect with further beta-blocker dosing, the patient developed profound bradycardia and later went into pulseless electrical activity cardiac arrest requiring cardiopulmonary resuscitation. Metabolic derangements and bradycardia later resolved with medical management, but unfortunately, the patient developed diffuse anoxic brain injury after the cardiac arrest and was declared brain dead.
