Contributor: Don Stader, MD Educational Pearls: Acute respiratory distress syndrome (ARDS) is a catch all term for when lung injury leads to fluid collection in the air spaces of the lungs Ventilatory management in ARDS patients involves lower FiO2 and PEEP than other patients and relies on lung protective ventilation strategies to prevent barotrauma Proning…
Read MoreContributor: Dylan Luyten, MD Educational pearls: Clinical management of COVID-19 is rapidly evolving, relying on case reports and clinical experience In just a month, the consensus around management of COVID patients with severe hypoxia has shifted from an early intubation strategy to other, non-invasive means Intubating early can quickly consume ventilator resources, require increased intensive…
Read MoreContributor: Peter Bakes, MD Educational Pearls: Peri-arrest patients present a particular challenge to ED providers, as the differential is broad and time is critical The differential for near cardiac arrest includes the “H’s and T’s”, just as in true cardiac arrest The 6 H’s include: hypoxia, hypo/hyperkalemia, hypovolemia (including shock states), hydrogen (acidosis), hypothermia The…

A 2019 study, randomized participants to 3 groups: 9 hours of sleep, 5 hours of sleep with weekend catch-up sleep, and 5 hours of sleep without catch-up sleep. In the sleep deprived (5…

Contributor: Charleen Gnisci, PharmD Educational Pearls: Causes of increased intracranial pressure may include intracranial hemorrhage, malignancy, and trauma. While definite treatment is to remove the offending cause, there are emergency medicine Non-pharmacologic methods include elevating head of bed and removing noxious stimuli Pharmacologic options include mannitol and hypertonic saline Hypertonic saline is best delivered through…
Read MoreAuthor: Gretchen Hinson, MD Educational Pearls: Breath stacking occurs when a patient is unable to expire fully before another inspiration In intubated/ventilated patients, this is because adequate time has not passed before exhalation Asthmatics are susceptible due to the prolonged expiratory phase Complications can include reduction in cardiac preload and cardiovascular collapse Pursed-lip breathing can…

Read MoreEducational Pearls: Acetaminophen overdose can also present in patients taking too much over the course of days to weeks – not just intentional ingestions If acute overdose is suspected, refer to the Rumak-Matthew nomogram to guide treatment based on time of ingestion and the time of level In chronic overdose, Tylenol levels will not…
Read MoreAuthor: Don Stader, MD Educational Pearls: 8014 patients with out-of-hospital cardiac arrest randomized to epinephrine vs placebo 30-day survival was not dramatically better between groups (3.2%in the epinephrine group and 2.4% in the placebo group) Functional neurological outcome was nearly identical at 2.2% and 1.9% of patients Adds to literature that epinephrine provides little important…
