ECG Blog #380 — What is "Swirl"?

Ken Grauer, MD

The ECG in Figure-1 — was obtained from an older woman with persistent CP ( C hest P ain ) over the previous day. Her symptoms lessened after Nitroglycerin — so the decision was made not to activate the cath lab. Do YOU agree with this decision? Figure-1: The initial ECG in today's case. MY Thoughts on the ECG in Figure-1: In a patient with CP that had been persistent over the previous day ( until Nitroglycerin was given ) — the initial ECG shown in Figure-1 is extremely worrisome.

Serial Hemoglobin / Hematocrit – Huh? Part 1

The Trauma Pro

The serial hemoglobin (Hgb) determination. We’ve all done them. Not only trauma professionals, but other in-hospital clinical services as well. But my considered opinion is that they are not of much use. They inflict pain. They wake patients up at inconvenient hours. And they are difficult to interpret. So why do them? I’m reposting this mini-series on serial hemoglobin draws in light of a new paper that was published in the Journal of Trauma Nursing.

Closed Head Injury – PECARN for < 3 Months: Rebaked Morsel

Pediatric EM Morsels

We all know that Gravity Works ! While this fact can adversely affect anyone, it offers the greatest challenge for those who cannot protect themselves , like children less than 3 months of age ! We last pondered this in 2011 Morsel , just a couple years after PECARN head injury data was published. Since that time there have been several studies externally validating the PECARN rule in all age groups and in multiple different countries.

ECG Blog #381 — Why was the Troponin Normal?

Ken Grauer, MD

The ECG in Figure-1 was obtained from a 60-ish year old man with a history of coronary disease ( including prior CABG ) — who presented to the ED ( E mergency D epartment ) with new CP ( C hest P ain ) of 3 hours duration , diaphoresis and nausea/vomiting. The patient was hypotensive at the time his initial ECG in Figure-1 was obtained. The decision was made not to immediately perform cardiac cath — because there is no ST elevation in Figure-1 — and because the initial troponin was negative.

Adjunctive Methylene Blue in Septic Shock?

RebelEM

Background: Sepsis can induce numerous physiologic derangements. At the most severe end, this includes endothelial dysfunction leading to increased vascular permeability, abnormal nitric oxide metabolism, and vasodilation (i.e. septic shock). Judicious fluid resuscitation is indicated in patients with signs of hypo perfusion but is often inadequate necessitating the administration of vasoactive medications.

Trick of Trade: Dual Foley catheter to control massive epistaxis

ALiEM

Massive epistaxis is considered a medical emergency that requires immediate attention. Symptoms of massive epistaxis include sudden and heavy bleeding from the nose, difficulty breathing, dizziness, and a rapid heartbeat. If left untreated, it can lead to significant blood loss, shock, airway obstruction, and even death. We report a case of a 50-year-old man with end stage renal disease with massive nasal bleeding from the left nostril, shortness of breath, and confusion.

A review of the utility of the ECG in Pediatric Syncope

PEMBlog

Syncope is described as a brief loss of consciousness and postural tone caused by transient global cerebral hypoperfusion. It is followed by a complete recovery. An estimated 80% of pediatric syncope is due to autonomic (vasovagal or neurocardiogenic) syncope. Our role as providers is to identify the patients who have a life-threatening etiology to their syncope.

In the TEAM trial conducted by the ANZICS group, 750 ICU patients in 49 hospitals in 6 countries were randomized to either early mobilization or usual care (which usually included in-bed physical therapy).
