Does My Patient with Chest Pain Have Acute Coronary Syndrome?

23 Nov
November 23, 2015

Acute Coronary SyndromeBackground: We have already discussed the value of a good history in assessing patients with chest pain on REBEL EM. What is known about chest pain is that it is a common complaint presenting to EDs all over the world, but only a small percentage of these patients will be ultimately diagnosed with Acute Coronary Syndrome (ACS). This complaint leads to prolonged ED length of stays, provocative testing, potentially invasive testing, and stress for the patient and the physician. For simplicity sake, we will say that, looking at the ECG can make the diagnosis of STEMI. What becomes more difficult is making a distinction between non-ST-Elevation ACS (NSTEMI/UA) vs non-cardiac chest pain. ED physicians have different levels of tolerance for missing ACS with many surveys showing that a miss rate of <1% is the acceptable miss rate, but some have an even lower threshold, as low as a 0% miss rate. Over testing however, can lead to false positives, which can lead to increased harms for patients. In November 2015, a new systematic review was published reviewing what factors could help accurately estimate the probability of ACS. Read more →

November 2015 REBELCast: All Vascular Access Episode

12 Nov
November 12, 2015

Vascular AccessWelcome to the November 2015 REBELCast, where Swami, Matt, and I are going to tackle a couple of topics in the world of Vascular Access. Peripheral intravenous (PIV) access is one of the most common procedures we perform in the emergency department (ED) and central venous catheter (CVC), although decreasing in frequency, has some very real complications associated with it. It is always good to question clinical practice, especially in procedures that we perform on a daily basis.  IV access is important to patient care for things that we may take for granted such as lab work and initiation of treatment. So with that introduction today we are going to specifically tackle:

Topic #1: Intravascular Complications of Central Venous Catheter (CVC) Access
Topic #2: US vs Landmark Technique for Peripheral IV Access

Ischemic Stroke Treatment Archive

09 Nov
November 9, 2015

Ischemic Stroke Treatment ArchiveI recently returned from the American College of Emergency Physicians (ACEP) Conference which took place from Oct. 26th – 29th, 2015 in Boston, MA.  There were really a lot of amazing talks by so many amazing speakers but one lecture in particular by David Newman, of SMART EM and The NNT fame, made me realize that there is just so much research on treatment of ischemic stroke, that I can’t even keep them straight.  So what I thought I would do is create an archive of all that research and continue to add to the list as more research is released.  I don’t know about you, but I find myself spending lots of time looking this information up every time I need it.  Read more →

Diabetic Ketoacidosis (DKA) Myths

02 Nov
November 2, 2015

DKARecently, I was asked to give a lecture to both my residents and nurses at the University of Texas Health Science Center at San Antonio (UTHSCSA) on some common DKA myths. Now this topic was originally covered by my good friend Anand Swaminathan on multiple platforms and I did ask his permission to create this blogpost with the idea of improving patient care and wanted to express full disclosure of that fact. I specifically covered four common myths that I still see people doing in regards to DKA management:

  1. We should get ABGs instead of VBGs
  2. After Intravenous Fluids (IVF), Insulin is the Next Step
  3. Once pH <7.1, Patients Need Bicarbonate Therapy
  4. We Should Bolus Insulin before starting the infusion

CPR in Out of Hospital Cardiac Arrest: Man vs Machine

26 Oct
October 26, 2015

CPR - Man vs MachineBackground: In cardiac arrest, high quality, uninterrupted CPR is essential to help improve survival rates. In theory, mechanical CPR should provide CPR at a standard depth and rate for prolonged periods without a decline in quality, which should help improve survival and survival with good neurologic outcomes. There are many types of mechanical chest compression devices but the two main technologies can be generalized as piston devices and load-distributing bands. The piston driven devices work by compressing on the chest in an up and down type of motion, similar to how we do manual CPR. The load distributing bands wrap all the way around the chest and shorten and lengthen which provides more of a rhythmic type of chest compression. No individual trials have ever shown superiority on clinically important outcomes for adult patients with OHCA, regardless of device. Read more →

REBEL Cast Wee: Our Top 5 AHA 2015 Guideline Updates for CPR and ECC

22 Oct
October 22, 2015

Top 5 AHA Guideline UpdatesIn case you have not heard or not read it on the twittersphere, the American Heart Association just released their 2015 Guidelines Update for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC) in Circulation. I am joined by Mr. Security, Matt Astin for this episode and we both read through this massive 15 part document and came up with our top 5 updates and recommendations. Now this is just a list of our top 5 new or updated recommendations, that caught our attention, but certainly there are other recommendations. If you want the cliff notes version of the updates look through part I, titled the executive summary or the Highlights PDF which we will attach on the blog, but certainly as always we recommend reading the full document to form your own interpretations and opinions.

The FELLOW Trial: An End to Apneic Oxygenation?

12 Oct
October 12, 2015

The Fellow TrialBackground: Every year there are a handful of “game changing” publications that truly change how we care for our patients. One such paper was a paper by Scott Weingart and Richard Levitan in the Annals of Emergency Medicine in 2011 on the topics of preoxygenation and apneic oxygenation (This paper was already reviewed on REBEL EM – Preoxygenation and Apneic Oxygenation). As many of us know, one of the most common and feared complications dealt with in critically ill patients requiring endotracheal intubation is hypoxemia. Hypoxemia can subsequently lead to cardiac arrest and death. Since the advent of apneic oxygenation this common complication seems to have decreased in occurrence, but is apneic oxygenation effective in all settings? Read more →

October 2015 REBELCast: The All Thoracotomy Episode

08 Oct
October 8, 2015

ED ThoracotomyWelcome to the October 2015 REBELCast, where Swami, Matt, and I are going to tackle a couple of topics in the world of Trauma, specifically ED Thoracotomy. Now we all know that ED thoracotomy is a last ditch salvage effort, performed under specific clinical circumstances, during a traumatic arrest. The purpose of the ED thoracotomy is to evacuate pericardial tamponade, control hemorrhage, improve coronary/cerebral blood flow, and if needed internal cardiac massage. The purpose of this podcast is to discuss specific indications where this already low yield procedure may have some benefit.

  • Topic #1: FAST US Examination as a Predictor of Outcomes After Resuscitative Thoracotomy
  • Topic #2: Blunt Trauma Thoracotomy

Screen Shot 2015-09-26 at 7.29.36 AMI recently gave a talk at my old alma mater (Texas A&M College of Medicine) on creating a Professional and Scholarly Community with FOAM in early September of 2015.  One of the things I was most amazed by was how many people had not heard of the concept of FOAM, but more importantly the number of questions I received after my talk on how to get started and how to consume FOAM.  Now many people in the FOAM world have posted blog posts, videos, and even podcasts on how to do this, but I thought I would write a blog post on how I keep up and stay organized for anyone who is new to the FOAM world or if someone simply asks you how to get started feel free to just refer them here.
