Mechanical Circulatory Support - Part 1

Much attention has been paid to targeted temperature management (TTM) in post-cardiac arrest patients. The evidence for this practice continues to evolve, and previous episodes of Critical Matters have covered this topic. In this episode, Dr. Zanotti focuses on other aspects of Neurological Support in the ICU for post-cardiac arrest patients. He is joined by Dr. Edilberto Amorin, a neurologist with subspecialty training in critical care and epilepsy. He has expertise in neurological intensive care, telemedicine, and multimodal brain monitoring with EEG. Dr Amorin is an Assistant Professor of Neurology at UCSF Weill Institute for Neurosciences and directs the Epilepsy and Clinical Neurophysiology Service at the Zuckerberg San Francisco General Hospital.

Hypotension and shock are both recognized as complications post-cardiac surgery. Some patients may develop more severe shock refractory to fluids and catecholamines. This response is also known as today's podcast episode, topic: vasoplegia after cardiac surgery. For this discussion, Dr. Zanotti is joined by Dr. Iqbal Ratnani, an intensivist who practices at the DeBakey Heart & Vascular Center and the Center for Critical Care at Houston Methodist Hospital. Dr. Ratnani is an Associate Professor of Clinical Anesthesiology & Critical Care for the Department of Anesthesiology and Critical Care at Weill Cornell Medical College. In addition, Dr. Ratnani is the Director of Critical Care Education at the Center for Critical Care. Additional resources: Vasoplegia: A Review. Igbal Ratnani, et al.

We pulled out another favorite out this week - Dr. Zanotti's deep-dive on tracheostomy emergencies. Tracheostomies are common in ICU patients. Every intensivist should be capable of recognizing and providing initial management to potentially serious complications associated with tracheostomies. Dr. Zanotti is joined by Drs. Laura Bontempo and Sara Manning, emergency physicians and educators with a special interest in the topic. Dr. Laura Bontempo is an associate professor of emergency medicine and serves as Assistant Director for Faculty Development & Resident Education in the Department of Emergency Medicine at the University of Maryland Medical School. Dr. Sara Manning is an Assistant Professor of Clinical Emergency Medicine, in the Department of Emergency Medicine at the Indiana University School of Medicine.

Today, we are revisiting one of our favorite episodes from last year - The Forgotten Patient. Dr. Zanotti focuses on the loved ones and families of critically ill patients and explores the topic through the lens of a cardiac arrest co-survivor. His guest is Kristin Flanary, a cognitive neuroscientist and social psychologist. Kristin is a co-survivor of cancer(twice) and a co-survivor of sudden cardiac arrest. She is also known for her social media alter ego – Lady Glaucomflecken. In 2022 Kristin co-founded Glaucomflecken LLC, where she works to advocate for caregivers and co-survivors of medical trauma and critical illness, community CPR and AED use, and sudden cardiac arrest survivorship. She has written about her experience as a co-survivor in medical journals and has received an EMS Cardiac Arrest Save Challenge Coin, the Citizen CPR Foundation’s '40 Under 40' award, and the American Heart Association’s Resuscitation Champion award.
