(Dis)utility of Orthostatics in Volume Depletion

05 Mar
March 5, 2018

Definition: Orthostatic hypotension (OH) is a form of low blood pressure that occurs with positional change (i.e. sitting up from lying down, standing up from sitting). It is commonly used for the diagnosis of volume depletion

Orthostatic Vital Signs

  • A reduction of systolic blood pressure (SBP) of at least 20 mm Hg
  • A reduction in diastolic blood pressure (DBP) of at least 10 mm Hg
  • An increase in heart rate (HR) by > 30 beats per minute

One of the above criteria must be met while measured 3 minutes after standing from a supine position.

Clinical Question: Are orthostatic vital signs useful in finding patients with occult volume loss? Do they add to our standard clinical assessment of patients? Read more →

REBEL Cast Ep 45: How to Build a Great Presentation

05 Feb
February 5, 2018

What’s Wrong With Lectures/Presentations Now?

  • Lecturing style has remained stagnant despite the fact that our understanding of how people learn has changed.
  • Most presentations make the supportive media (i.e. slides) the focus of the presentation without thought about the story or the delivery.
  • Lectures are too focused on the educator instead of focusing on the needs of the learner.

Topics in Post-ROSC Care

29 Jan
January 29, 2018

Background: Post-cardiac arrest patients are among the sickest groups of patients seen in the Emergency Department. They are difficult to study, which leads to endless questions about how to best care for them. Below we address the available evidence on four of these controversies: oxygen therapy, hemodynamic management, cardiac catheterization and head CT. We recognize the limitations to the available data and attempt to offer the best recommendations we can. Read more →

REBEL Cast Ep 44: IO vs IV in Out-of-Hospital Cardiac Arrest (OHCA)

25 Jan
January 25, 2018

Background: Placement of vascular access for administration of resuscitation drugs and fluids is a common procedure in the management of out of hospital cardiac arrest (OHCA). While intravenous (IV) placement has been the standard approach for decades, intraosseous (IO) access is rapid and safe and may be the preferred approach due to fact that the bone marrow does not collapse during shock states as peripheral veins often do. Despite it’s advantages, there are concerns about IO placement because of the potential for drugs to pool in the marrow and not circulate. Prior studies have shown an association with tibial IO placement and decreased rate of ROSC though no association with worse neurologic outcomes (Feinstein 2017). Read more →

Post-Partum Hemorrhage

15 Jan
January 15, 2018

Definition: Blood loss > 500 ml after a delivery (or > 250 ml after an abortion). The management of post-abortion hemorrhage is similar to that of post-partum hemorrhage (PPH).


  • Uterine atony (~ 50% of cases)
  • Retained products of conception (POCs)
  • Cervical lacerations
  • Uterine perforation
  • Uterine Inversion
  • Abnormal placentation (accreta, increta, percreta)
  • Coagulopathy


  • Occurs in 1-2% of patients undergoing a first trimester surgical abortion
  • Most common cause of abortion-related mortally in 2nd trimester
  • Risk increases with increasing maternal age
