Background: In end-stage renal disease (ESRD) patients on hemodialysis (HD), infection is the second most common cause of mortality after cardiovascular disease (Sarnik 2000). Because of the systemic inflammation and increased capillary permeability, septic patients are at significant risk for fluid imbalances and frequently require large volumes of crystalloids. The Surviving Sepsis Campaign guidelines provide a strong recommendation with low quality of evidence for administering a 30mL/kg fluid bolus within 3 hours of recognition of sepsis-induced hypoperfusion (Rhodes 2016). Further fluid administration should be guided by hemodynamic assessment (bedside echocardiography, passive leg-raise, etc.). In the general population, this early administration of fluids to patients with hypotension or sepsis-induced hypoperfusion has been associated with improved outcomes. However, there is significant confusion regarding the effects of a large 30mL/kg bolus on ESRD patients due to a lack of studies. While these patients may appear, volume overloaded on physical exam, they may be intravascularly volume deplete. Physicians may be hesitant to administer a large fluid bolus in ESRD patients because of the risk of precipitating cardiogenic shock, pulmonary edema, and respiratory failure. In fact, multiple studies show that patients who have ESRD are less likely to receive the full 30mL/kg fluid bolus compared to non-ESRD patients (Lowe 2018, Truong 2019, Dagher 2015). Furthermore, some studies show equivalent outcomes between ESRD patients who receive the full bolus and those who do not. We will review two studies that examined this topic.

I am fortunate to work in a hospital system that is very forward thinking.  We have a phenomenal relationship with our intensivists, and I have been fortunate enough to have several discussions with them about how we are managing COVID-19 in our ICUs.  For full transparency, I don’t work up in the ICU, but had the opportunity to discuss what we are doing in our ICUs with one of our intensivists (ECMO, steroids, Remdesivir, etc...).  We are doing something different in San Antonio that I thought was worth discussing on this podcast that may be a feasible option for some institutions and some patients, but not all. If there is one thing this disease has taught me, that is one size does not fit all.

Introduction: Emergency physicians rarely are involved in tube exchanges; I can’t remember the last time I had to do one. However, during the COVID19 surge, we found ourselves boarding intubated patients for days and even weeks as our ICUs were filled to the brim. With our ICU teams so busy, it became increasingly important for us to aid in critical care management where we could. Initially this was simply with lines and hemodynamic monitoring but, tube exchange became important. A number of our boarding patients developed considerable mucous plugging and tube obstruction that could not be cleared by suction. Reintubation with a fresh tube, while well within our scope, creates unnecessary risks - aerosol generation, increased provider exposure and possible harm to patient if intubation proves challenging. Tube exchange over a bougie seems to make a lot of sense.

Note: Due to the lack of experience most EM clinicians have with this procedure and the fact that it is a high-risk one, it may be best to consult anesthesia to help with the procedure if they are available. We acknowledge that this may not be possible if that service is stretched thin due to circumstances.

Background: Epinephrine remains a staple in cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA).  However, the optimal dose, timing, and route of administration are still unknown.  Standard dosing of epinephrine is 1mg every 3 to 5 minutes via the intravenous (IV) or intraosseous (IO) route. IO lines are quicker to establish and have a higher first-attempt success rate compared to IV access. Rapid placement and ease of use minimizes delays for critical patients requiring quick access. The literature, although methodologically limited, is mixed about the use of IV vs IO access for epinephrine in OHCA.

The protected code blue is designed to keep your staff safe when managing a patient with COVID-19 who has a sudden cardiac arrest. You will continue to do high quality CPR, defibrillation (if indicated), give code medications, and BVM with airway management, now with a drape. I’m going to outline a suggested plan for how to conduct a protected code blue at your hospital. You will need to modify it to fit your hospitals requirements.
