    Episode 25 – Interpreting the TTM2 Trial – 33C versus Controlled Normothermia


    A new multicenter trial published in NEJM, commonly known as the “TTM2” trial, evaluated treating patients resuscitated from out-of-hospital cardiac arrest with targeted temperature management to 33C versus controlled normothermia, and found that outcomes were equivalent.  Does this mean the end of TTM as we know it?  In this podcast, Dr. Benjamin Abella presents a comprehensive argument why he believes that such pronouncements are premature and not consistent with the larger body of laboratory and clinical science over the past 20 years. He discusses TTM2 in context of recent work from France (the Hyperion study), as well as work from the US and Japan, suggesting that patient selection is key.  TTM may not be needed for patients with favorable characteristics (witnessed arrest, bystander CPR, no evidence of shock) but still may be required for patients with less favorable characteristics (non-shockable arrest rhythms, no bystander CPR, evidence of shock).   Also join us for a free live Zoom webinar on June 24 at 4 PM EDT US time to discuss the TTM2 trial.

    Episode 24 - ECG Timing and Post-Cardiac Arrest Cath Findings


    Electrocardiography (ECG) represents a central diagnostic tool in the post-arrest evaluation of patients resuscitated from out-of-hospital cardiac arrest (OHCA), and it should be acquired immediately after achievement of ROSC to identify the need for an urgent coronary angiography, which is indicated only in the case of ST-segment elevation myocardial infarction (STEMI). While resuscitation guidelines are clear in the recommendation and importance of obtaining an ECG during the post-ROSC phase, they don’t provide specific instructions about the best time for ECG acquisition after ROSC.   In this context some have proposed that the timing of ECG post-ROSC may have an impact in the early post-ROSC phase, and that the ECG could reflect ischemia secondary to cardiac arrest more than or in addition to ischemia due to coronary artery pathology, possibly leading to overdiagnosis of STEMI.   In episode 24 of the TTM Academy Podcast we review a recent study published in JAMA Network Open, by authors Enrico Baldi, Simone Savatano and colleagues, who performed a retrospective, multicenter cohort study evaluating whether the time from ROSC to ECG acquisition is associated with the percentage of false-positive ECG findings for STEMI in patients resuscitated from OHCA.   Citation of the study and accompanying Editorial commentary: Baldi E, Schnaubelt S, Caputo ML, et al.

    Episode 23 - Cardiac arrest, up close and personal: A discussion with @Lglaucomflecken


    While we have focused on the science of targeted temperature management and other care strategies for critically ill survivors, it is important for us to remember that real people experience cardiac arrest and the consequences. In this unique episode, Dr. Benjamin Abella interviews Kristin Flanary, who jumped into action to provide 10 minutes of bystander CPR to her husband, Dr. Will Flanary, who has thankfully made a full recovery. You may know Kristin and Will as @lglaucomflecken and @dglaucomflecken , well-known on twitter – we are grateful that Kristin has chosen to go public with her story and support advocacy for cardiac arrest and post-arrest care.   Suggested readings on bystander CPR and survivorship: Brian Anderson.

    Episode 22 - The Role of Oxygen in Critical Illness


    The role of oxygenation during critical illness remains a major question.  Is extra oxygen harmful or helpful? What oxygen levels should we target, both for respiratory failure and for patients after cardiac arrest? Dr. Benjamin Abella discusses these topics, and reviews a hot-of-the-press work from European investigators (the “HOT-ICU”) trial, published in New England Journal of Medicine this month. The paper evaluates two different oxygen targets for patients with respiratory failure – implications for this work as it pertains to cardiac arrest will be discussed.   Key publications: Schjørring OL, Klitgaard TL, Perner A et al.

    Episode 21 - IHCA during the COVID-19 pandemic: Implications of COVID-19 for resuscitation care


    Critical illness from COVID19 remains a major challenge to health systems worldwide. When patients progress to in-hospital cardiac arrest (IHCA), what is the chance of survival?  Studies have so far revealing conflicting answers to this important question.  What is the role of post-arrest care bundles, including TTM, in the care process?  Dr. Felipe Teran will lead a conversation with Dr. Oscar Mitchell, who served as the lead author in a new multicenter study of COVID19 IHCA survival, to be presented as a late-breaking abstract at the Resuscitation Science Symposium.   Key publications: Girotra S, Tang Y, Chan PS, Nallamothu BK; American Heart Association Get With The Guidelines–Resuscitation Investigators.

    Episode 18 - Survivorship: The new frontier in post-arrest care


    Dr. Abella discusses a very recent American Heart Association scientific statement on cardiac arrest survivorship, increasingly recognized as an important topic around the globe. While many studies have evaluated survival to hospital discharge, or even survival at 90 or 180 days post-arrest – survival is not enough. Increasing data suggest that even among “good” neurologic survivors (those with Cerebral Performance Category 1 or 2), life-limited challenges remain, including depression, PTSD, cognitive deficits and other challenges to quality of life.   Key readings:  Sawyer KN, et al.
