Fatal pulseless electrical activity in an African American man with natural killer/T-cell leukemia/lymphoma and myocardial involvement

Application of ultrasound in pulseless electrical activity (PEA) cardiac arrest

Atropine, halothane, and pulseless electrical activity.

C ardiovascular depression from halothane overdose is a well-described cause of cardiac arrest in children undergoing anesthesia. In Salem et al’s (1) report of cardiac arrests in infants and children, seven of 73 were related to overdose of halothane. In Keenan and Boyan’s (2) landmark article on cardiac arrest due to anesthesia, five of six pediatric arrests were due to halothane excess, with...

Establishing An Asphyxial Pulseless Electrical Activity Arrest Model In Rabbits

Objective:Pulseless Electrical Activity (PEA) is an increasingly frequent cardiac rhythm in the arrested patient. We determined to establish an intact animal model of asphyxial PEA of variable duration that may be utilized for evaluation of agents of potential benefit in this scenario. Method:Instrumented adult New Zealand White rabbits underwent induction of hypoxic PEA via tracheal cross-clam...

Tissue plasminogen activator in cardiac arrest with pulseless electrical activity.

BACKGROUND Coronary thrombosis and pulmonary thromboembolism are common causes of cardiac arrest. We assessed whether the administration of tissue plasminogen activator (t-PA) during cardiopulmonary resuscitation would benefit patients with cardiac arrest and pulseless electrical activity of unknown or presumed cardiovascular cause. METHODS Patients who were older than 16 years of age and who...

Outcome of out-of-hospital postcountershock asystole and pulseless electrical activity versus primary asystole and pulseless electrical activity.

OBJECTIVE In the prehospital setting, countershock terminates ventricular fibrillation (VF) in about 80% of cases. However, countershock is most commonly followed by asystole or pulseless electrical activity (PEA). The consequences of such a countershock outcome have not been well studied. The purpose of this investigation was to compare the outcome of prehospital VF victims shocked into asysto...
