Mechanical Ventilation and ARDS – Podcast Summary and References
This is the sixth 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 as a retrieval OBGYN/MFM and is one of our Assistant Medical Directors for the flight program.
The topic of this podcast is Mechanical Ventilation and ARDS in pregnancy. Although respiratory distress requiring intubation and ARDS in pregnancy is not very common, it is more common than some of the other pathologies we have discussed recently. Mechanical ventilation of the pregnant patient can be intimidating, but rest assured that if you have the capabilities to manage other patients on a vent, you can manage the pregnant patient. Generally speaking solid outcomes data is sparse and, generally speaking, most guidelines recommend vent management of mechanical ventilation in patients with or without ARDS similarly to non-pregnant patients…with a few exceptions. This podcast reviews the basics of ARDS and evidence-based management. It reviews some specific features of obstetric physiology and fetal gas exchange that are important to keep in mind. Finally, we will review what guidance is available and review general recommendations for managing these patients in transport.
For additional learning and a more in-depth review of the evidence check out this talk on gas exchange and mechanical ventilation in critically ill patients by Dr. Allison Lankford (part of the amazing Maryland CC Project lecture series): http://maryland.ccproject.com/2023/05/30/lankford-gas-exchange-and-pulmonary-ventilation-in-the-critically-ill-obstetric-patient/

MDCast w/ Dr. Michael Lauria - Amniotic Fluid Embolism Dec 22, 2023

Show notes

This is the fifth 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 as a retrieval OBGYN/MFM and acts as one of our Assistant Medical Directors for the flight program.
The topic of this podcast is Amniotic Fluid Embolism (AFE). Another rare, but devastating disease that can often progress rapidly to cardiac arrest. In this podcast, we go through the epidemiology and definition/diagnosis of the disease. We also go into depth on underlying pathophysiology and the current hypotheses on what causes AFE. Spoiler alert: it’s not as simple as an embolism of amniotic fluid. Then we review the management, specifically focusing on the management of acute right heart failure in the setting of abrupt and pronounced pulmonary hypertension. Finally, Dr. Garchar and I deliver some spaced repetition and go over the management of maternal cardiac arrest, in the likely event that AFE progresses to that point.

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.

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.

New Global Definition for Acute Respiratory Distress Syndrome

MDCast w/Dr. Michael Lauria - Peripartum Cardiomyopathy Sep 08, 2023

Show notes

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.

Warm Fluids In Resuscitation: Current Evidence Aug 25, 2023

Show notes

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.
