In this episode, Dr. Sergio Zanotti discusses the assessment of peripheral perfusion as a tool to guide treatment in septic shock. Specifically, he dives into Capillary Refill Time. He is joined by Dr. Eduardo Kattan, a critical care and anesthesia physician. Dr. Kattan is an Assistant Professor at the Pontificia Catholic University of Chile, where he also serves as Adult Critical Care Program Director and Director of Research and Academics in the Department of Critical Care Medicine. A prolific investigator, he focuses his research on septic shock and medical education. Dr. Rattan is the Co-Principal Investigator of the recently published ANDROMEDA-SHOCK 2 clinical trial.

In a previous episode, Dr. Sergio Zanotti explored the importance of challenging dogma, particularly when the supporting evidence is weak or absent. Today, he continues that discussion by examining critical care practices that persist despite a lack of strong scientific validation. He's joined by Dr. Mervyn Singer, an internationally recognized leader in critical care medicine. Dr. Singer is a professor of intensive care medicine at University College London and a distinguished clinician, researcher, and educator. Through his research, publications, and dynamic presentations, he has inspired Dr. Zanotti — and countless intensivists worldwide — to think critically, challenge conventions, and push the boundaries of our field.
