Bolus Thrombolytic Infusions During CPR for Patients With Refractory Arrest Rhythms: Outcome of a Case Series, ,

Thrombolytic therapy has been accepted in the treatment of acute myocardial infarction. Given historical recommendations that thrombolytic therapy is contraindicated in patients receiving CPR, its potential clinical benefit for facilitating conversion of rhythm in patients in refractory cardiac arrest has not been investigated. We present three case reports in which patients with confirmed acute myocardial infarction had a witnessed cardiac arrest in the ED. Standard Advanced Cardiac Life Support measures failed in all three cases. A bolus infusion of tissue plasminogen activator was administered during CPR in refractory ventricular fibrillation (two cases) and pulseless ventricular tachycardia (one case). Patients were given tissue plasminogen activator and had defibrillation, followed by a spontaneous return of circulation, with resuscitation and subsequent discharge. No postarrest sequelae were observed as a result of thrombolytic use during the resuscitative process. We conclude that bolus thrombolytic infusions during CPR may facilitate spontaneous return of circulation in select patients with confirmed acute myocardial infarction, witnessed cardiac arrest in the ED, and refractory ventricular fibrillation or tachycardia.
