Occult Causes of Non-Response to Vasopressors

13 Jul
July 13, 2017

Intro: Vasoactive substances are powerful therapeutic medications that can boost a patient’s blood pressure and perfusion to target organs. They are often used in resuscitation to support tissue perfusion though their benefits are mostly unproven and may be harmful in certain circumstances (i.e. hypovolemia, hemorrhage). The cognitive response to hypotension should not be reaching for […]

Targeted Temperature Management in Out-of-Hospital Cardiac Arrest: 33°C or 36°C?

19 Jun
June 19, 2017

Background: In 2002, the New England Journal of Medicine published two studies that changed the management of post-cardiac arrest patients by showing improved outcomes in patients treated with therapeutic hypothermia (32°C-34°C) for at least 24 hours. (Bernard 2002, Hypothermia 2002).  The landscape changed again in 2013 with the publication of the Targeted Temperature Management (TTM) trial […]

Acute Salicylate Toxicity, Mechanical Ventilation, and Hemodialysis

May 25, 2017

Background: Salicylates are common substances that can be purchased over the counter. They are readily available, and in the setting of an overdose, can be fatal [1]. Initially, as salicylates are metabolized, they can induce a respiratory alklalosis. This is then followed by an anion gap metabolic acidosis. Due to the metabolic derangements induced by […]

The WOMAN Trial: Early TXA in Post-Partum Hemorrhage

May 22, 2017

Background: Post-partum hemorrhage (PPH) is the leading cause of maternal death worldwide. It is typically defined as > 500 ml of blood loss within 24 hours of giving birth. However, PPH encompasses a broad spectrum of disease from mild oozing over hours to rapid exsanguination and death. The burden of mortality from PPH is shouldered […]

Episode 38 – Do All Submassive PE’s Require Treatment with Thrombolysis?

15 May
May 15, 2017

Background: There has been very little robust evidence published on the long-term outcomes of systemic thrombolysis in acute submassive PE.  Many advocate for the use of systemic thrombolysis to reduce morbidity (complications from chronic pulmonary hypertension) and mortality. The PEITHO trial compared systemic thrombolysis (with tenecteplase + heparin) vs no systemic thrombolysis (placebo + heparin) […]
