Contributor: Ricky Dhaliwal, MD Educational Pearls: Hypotension in patients requiring intubation should be resuscitated as much as possible While intubating, the negative inspiratory pressure goes away decreasing cardiac preload and worsening hypotension Phenylephrine can be given via push doses to increase blood pressure from alpha agonism For sedation, avoid propofol with hypotension and opt for…
Read MoreContributor: Aaron Lessen, MD Educational Pearls: Refractory ventricular fibrillation, defined as 3 defibrillation shocks without resolution, was studied via RCT looking to compare ECMO with cardiac cath vs. typical resuscitation After 30 patients (15 each arm), the trial was stopped because such a significant benefit seen in the ECMO arm 6 patients survived and 3…
Read MoreContributor: Aaron Lessen , MD Educational Pearls: Patients on 10L or more of oxygen per minute in the ICU were randomized to oxygen goals of 90% or 96% to compare 90-day mortality rates Mortality rates were about 42% for both of oxygen target groups, indicating no significant difference References Schjørring OL, Klitgaard TL, Perner A,…
Read MoreContributor: Aaron Lessen, MD Educational Pearls: The use of oxygen is controversial when treating patients with certain conditions, like MI’s, stokes, or ARDS because adverse outcomes have been demonstrated with using high oxygen concentrations. The Oxygen ICU trial looked at using higher and lower oxygen levels in treating intubated ARDS patients and found that mortality…
Read MoreContributor: Aaron Lessen, MD Educational Pearls: Traditional teaching has shied away from using vasopressors through peripheral IVs Tissue necrosis from extravasation is cited as a risk of use of vasopressors through a peripheral site However, risk of extravasation is low (2-4%) and even more rarely results in significant complications Using an IV that is more…
Read MoreContributor: John Winkler, MD Educational Pearls: Unstable ventricular tachycardia (VT) typically manifests with syncope, shortness of breath, diaphoresis and/or chest pain with hemodynamic instability Electrical cardioversion of unstable ventricular tachycardia is first line treatment Starting with a higher energy level (or just using the maximum) when performing cardioversion may set you up for better success…
Read MoreContributor: Aaron Lessen, MD Educational Pearls: Mechanical CPR (machine assisted compression devices) remains a hot topic of debate in emergency medicine Machine assisted CPR has been advocated to provide more consistent compressions in cardiac arrest and free up staff for other tasks. However, multiple studies have shown mechanical CPR provides no significant survival benefit yet…
Read MoreContributor: 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…
