FOAMcast - An Emergency Medicine Podcast

We cover several excellent post on rashes, including:

Next, we dive into core content on platelet problems including problems caused by drugs, immune thrombocytopenic purpura (ITP/idiopathic thrombocytopenic purpura) and thrombotic thrombocytopenic purpura (TTP) using Tintinalli Chapter 233 (8th ed) and Rosen's Chapter 122 (7th ed) as a guide.

We cover ultrasound guided pericardiocentesis using the posts from EMin5, CoreEM, and the Ultrasound Podcast.

Then, we delve into core content on the pericardium using Rosen’s (8th ed) Chapter 82 and Tintinalli (8th ed) Chapter 55 covering pericardial effusions, pericarditis, and myocarditis.

We cover a post by Dr. Rory Spiegel, EMNerd: The Case of Differing Perspectives, on the results of the ATACH-2 trial on blood pressure control in intracranial hemorrhage (ICH). This study sought to determine the safety and efficacy of the

Population: adults (>18 y/o) with ICH on CT scan, GCS ≥ 5 and <4.5 hours since symptom onset (changed mid-study)

Intervention: Reduce and maintain the hourly minimum systolic blood pressure in the range of 110 to 139 mm Hg throughout the period of 24 hours after randomization ("intensive treatment"). Preferred agents for blood pressure control in order of preference were 1. nicardipine 2. labetalol (diltiazem or urapidil if not available)

  • Mean minimum in hours 0-2: 128.9±16 mm Hg

Control: Reduce and maintain the hourly minimum systolic blood pressure in the range of 140 to 179 mm Hg throughout the period of 24 hours after randomization.

  • Mean minimum in hours 0-2: 141.1±14.8 mm Hg

Outcome: The primary outcome was the proportion of patients who had moderately severe or severe disability (modified Rankin scale score (mRS) 4-5) or those who had died (mRS 6; hereafter referred to as “death or disability”) at 3 months.

  • death or disability: Intensive treatment = 186 participants (38.7%) vs Standard treatment = 181 (37.7%)

We also discuss the history of blood pressure control in ICH and the pendulum swing on this in recent years, using an episode of the Skeptic's Guide to Emergency Medicine, Episode 73. This episode covers the Interact-2 trial.

Core Content

We delve into core content on ICH using Rosen’s (8th ed) Chapter  and Chapter in Tintinalli (8th ed).

We also discuss the PATCH trial with regard to ICH management in patients on antiplatelet agents, discussing a REBELEM post on this trial.

Just in time for the new interns, we answer the most common question asked of us - our favorite resources to use on shift.

Free Open Access Medical Education (FOAM) exists in forms that are suitable for self-study or function as resources and those that are easy to use resources to consult on shift, Just In Time (JIT) Resources. We review our favorite FOAM JIT resources.

We cover a Scancrit post on the Back Up Head Elevated (BUHE) intubation position.  This post details a multicenter retrospective observational study by Khandelwal et al in Anesthesia & Analgesia.  Intubating with the head elevated (ear to sternal notch) and the back of the bed up reduces complications.

We delve into core content on the esophagus using Rosen’s (8th ed) Chapter 71 and Chapter 77 in Tintinalli (8th ed). We discuss dysphagia, food impaction, and esophagitis.

We cover pearls from smaccDUB (Social Media and Critical Care Conference in Dublin, Ireland), Day 3. We are here thanks to the Rosh Review.

Dr. Scott Weingart - "Post-Intubation Sedation"

  • Analgesia first. Try a hydromorphone 1mg push while you're waiting for the fentanyl drip. The endotracheal tube is uncomfortable.
  • Minimize sedation. There's this principle: eCASH: early Comfort using Analgesia, minimal Sedatives and maximal Humane care [1]. 
  • Sedation: go for dexmedetomidine if you have it (but it's expensive) or propofol. This is supported by the Society of Critical Care Medicine (SCCM) Pain, Agitation, and Delirium guidelines [2].
  • Be careful with rocuronium.  The long duration of rocuronium means that you can't assess for pain or discomfort so you must be responsible and get these

Dr. David Carr - "The Aorta Will #!&?% You Up"

Dr. Kathleen Thomas - "Oh Sh**! They’re bombing the hospital!"

We should not need a website entitled STOPBOMBINGHOSPITALS.ORG but, unfortunately, over the past 4 years, 400 hospitals have been bombed. This passionate, wrenching talk is a "must see" and "must listen" when the free talks are released on the SMACC podcast over the course of the next year.

#smaccDUB day 2

Dr. Reuben Strayer - “Disruption, Danger, and Droperidol: Emergency Management of the Agitated Patient."  

Dr. Strayer presented a brilliant talk on dealing with the quintessential Emergency Medicine patient - the undifferentiated acutely agitated patient. These patients are high risk and require emergent stabilization and resuscitation.

Dr. Haney Mallemat - "The PEA Paradox"

The typical way we think about PEA, the "H's and T's," is overly complicated. Further, we are horrendous at pulse palpation (see this for more), and so what we think is PEA may not actually be PEA.  Dr. Mallemat proposed QRS duration as one way to think about PEA, although this has limitations.

Dr. Michele Dominico - "How Usual Resuscitative Maneuvers Can Kill Paediatric Cardiac Patients"

Interventions we jump to in sick patients - oxygenation, ventilation, vasopressors - these can kill pediatric patients with cardiac pathology. She gave examples of some high yield pearls in these already terrifying patients.

Interesting and Ridiculous Research Pearls from Drs. Ashley Shreves and Ryan Radecki

  • Perception of dyspnea and pulmonary function tests change with stress - and rollercoaster rides.  Rietveld S, van Beest I. Rollercoaster asthma: when positive emotional stress interferes with dyspnea perception. Behaviour research and therapy. 45(5):977-87. 2007. [pubmed]
  • Cured pork for epistaxis? Possibly. Researchers will try everything, especially if it involves bacon. Humphreys I, Saraiya S, Belenky W, Dworkin J. Nasal packing with strips of cured pork as treatment for uncontrollable epistaxis in a patient with Glanzmann thrombasthenia. The Annals of otology, rhinology, and laryngology. 120(11):732-6. 2011.

We are at SMACC in Dublin - thanks to the Rosh Review, an excellent board review question bank. Here are some of our favorite pearls.

Do We Make Saves?

Dr. Mervyn Singer "Is Survival Predetermined in the Critically  Ill?"

  • Many critical care studies are negative, but in some cases this may be because critically ill patients don't have a uniform prognosis.
  • Dr. Singer argues that some people may be "destined to die" and some may be "destined to live."  So, it's not really us "saving the patient", it's just the math playing out. Interventions may be harmful or futile in one group but beneficial in the other.  For example, Dr. Singer references the CORTICUS trial of steroids in septic shock. This was a negative trial.  Dr. Singer asserts that some evidence (of not great quality), purports that the sickest patients could benefit from steroids, while this same intervention could be deleterious in the healthier ones.
  • Problem: many of the studies that go back and re-analyze these groups looking at the sickest or least sick patients? They perform subgroup analyses, a form of data dredging that must be taken with a huge grain of salt.

Favorite Pearls

Dr. Suzanne Mason - "Acute Care of the Elderly"

  • Hospital admission may not benefit geriatric patients - interdisciplinary interventions involving nurses, consultants, pharmacists, physical therapy may be best.
  • If there is a single, free intervention that providers can do it's assessing for polypharmacy. Polypharmacy in the elderly is a huge problem.  Check the patient's medication list and beware adding new medications that may not be absolutely necessary.

Dr. Victoria Brazil - "So You Think You're a Resuscitationist?"

  • The Dunning-Kruger effect is real in medicine and this is why we MUST have and provide feedback.  A review of the Dunning-Kruger effect can be found here.  Essentially, people tend to overestimate what they know (i.e. overly confident in their knowledge). The exception?  Masters tend to underestimate their knowledge.
    • Our perception of reality is very skewed so, again, feedback is crucial. For example, Cemalovic and colleagues found that intubators underestimated the time they took to intubate: they estimated 23.5 seconds on average vs the 45.5 seconds intubation actually took. Additionally, they thought 13% of their patients desaturated during intubation but 23% actually desaturated.
