The FlightBridgeED Podcast

Disseminated Intravascular Coagulation  This is the fourth of a special podcast series on obstetric critical care.  I am joined on this series by Dr. Elizabeth Garchar, MD, FACOG.  She is an OB/GYN and Maternal Fetal Medicine (MFM) specialist who has a particular interest in obstetric critical care.  She is also unique in that she flies regularly with our critical care transport teams and acts as one of our Assistant Medical Directors for the flight program.  So, Dr. Garchar has unique insight into managing this population in transport. The topic of this podcast is Disseminated Intravascular Coagulation (DIC) in the pregnant patient.  Although very rare, this disease carries a high morbidity and mortality.  The key features are the disease are diffuse and dysregulated coagulation that causes consumption of clotting factors (resulting in a paradoxical coagulopathic state), widespread endothelial damage, and is essentially always the result of some other disease process.  In this podcast we go over how critical care transport crews can recognize DIC and identify the underlying process causing it.  In addition, Dr. Garchar and I review the management in the transport environment and pearls regarding treating coagulopathy.  In the podcast we give a shout out to a phenomenal OB Critical Care course that is put on by Banner University Medical Center and the Society for Maternal Fetal Medicine.  Unfortunately, it’s a little late to sign up for this year’s session (November 2023), but put it on your radar for next year!  Here is a link to the brochure and conference content to give you an idea.  There is also a healthy component of simulation education.  I have no conflict of interest with this course at all…it’s just a phenomenal educational opportunity. https://s3.amazonaws.com/cdn.smfm.org/media/1807/Brochure-Banner(FINAL).pdf References 1.          Erez O.

Join Eric and Will Heuser, PharmD, discussing "The Influence of Low pH on Efficacy of Critical Care Pharmacology." Changes in acid-base balance have a profound influence on many aspects of the action of drugs. This is illustrated by data on the absorption of drugs from the stomach and intestine, changes in the distribution of drugs between plasma and cells, and the effect of changes in pH. Join us as Will breaks down the pathophysiology and decision-making in these low pH states. When do we deploy sodium bicarbonate? Is there a trade-off?  How is pharmacology affected by low pH states?  This episode is a can't-miss, with the brilliant Will Heuser, PharmD, BCCCP, MS, EMT-P, FP-C.

Since the 2012 Berlin Definition of the Acute Respiratory Distress Syndrome (ARDS), several developments have supported the need for an expansion of the definition, including the use of high-flow nasal oxygen (HFNO), expanding the use of pulse oximetry in place of arterial blood gases, use of ultrasound for chest imaging, and the need for applicability in resource-limited settings. Join Eric as he dives into the previous ARDS definitions, the pathophysiology around "PseudoARDS," and the new global definition.

This is the third episode of a special podcast series on obstetric critical care.  Although I am the sole host of this podcast, the content was reviewed and edited by Dr. Elizabeth Garchar, MD, FACOG.  She is an OB/GYN and Maternal Fetal Medicine (MFM) specialist who has a particular interest in obstetric critical care.  She is also unique in that she flies regularly with our critical care transport teams and acts as one of our Assistant Medical Directors for the flight program.  So, Dr. Garchar has unique insight into managing this population in transport. The topic of this podcast is peripartum cardiomyopathy.  Acquired cardiac conditions in otherwise healthy pregnant patients can be a serious and life-threatening condition.  Sometimes, critical care transport crews are called to transport pregnant or recently postpartum females with severe, acquired cardiomyopathy or in frank cardiogenic shock.  This podcast reviews the presentation, underlying pathophysiology, and management of this patient population.   References  1.          Arany Z, Elkayam U.

In this episode, Eric looks at warm fluids... or lack thereof in resuscitation. We will cover the current evidence around hypothermia in resuscitation secondary to the infusion of cold IV fluids. We discuss current strategies in warming fluids before administration in warm and cold ambient environments and the impact on body systems that ultimately contribute to increased mortality.

Calcium administration to trauma patients has become a hot topic with the rise of the “Lethal Diamond."  While evidence exists regarding the association between hypocalcemia and mortality, it remains unclear whether hypocalcemia is the problem or simply a finding secondary to critical injury.  In this podcast, Dr. Lauria reviews the evidence behind calcium administration in trauma and identifies which patients, given the available evidence, might benefit from calcium administration.

In this podcast, Eric discusses the art of having a "Resuscitative Mindset" when performing advanced airway management with guest host Kevin Collopy. When is it ok to perform advanced airway management rapidly? Is it ever ok? When do we deploy delayed sequence strategies?  Should we always use a "Resuscitative" sequence intubation mindset regardless of our assessment findings?  So much good conversation about all things airway and decision-making.
