Recorded live at the Critical Care Canada Forum 2024, this episode is part of our special Cardiac ICU Series.

Dr. Rebecca Mathew, cardiologist and critical care specialist at the University of Ottawa Heart Institute, joins us to discuss the latest refractory cardiac arrest practice updates, including antiarrhythmic drugs, defibrillation strategies, and the role of ECPR.

Chapters:

• Defining refractory cardiac arrest

• Antiarrhythmic drugs: amiodarone vs. lidocaine

• Defibrillation strategies: vector change and double sequential defibrillation

• Emerging therapies: stellate ganglion blocks and electrical storm management

• ECPR: who qualifies and what the trials say

• Equity and feasibility challenges in cardiac arrest management

• ICU recovery clinics and patient-centered outcomes

• Clinical trials: barriers to enrollment and the need for change
