Chest Pain: Coronary CT Angiography in the ED

CT Scanner It is well known that taking a good history and physical, getting a non-ischemic EKG, and serial cardiac biomarkers, results in a risk of death/AMI of <5% in 30 days. Patients, in whom you still suspect have CAD, should undergo provocative testing within the next 72 hours based on the AHA/ACC guidelines. Their guidelines deem provocative testing as including:

Exercise treadmill stress test,
Myocardial perfusion scan,
Stress echocardiography, and/or
Coronary CT angiography (CCTA).

Trick of the Trade: Fluorescein for lost contact lens

A patient’s contact lens broke when she was trying to take it off. She feels the pieces are still inside her eye, but she was unable to fish them out. When you look through the slit lamp, you are unable to to see whether there are contact lens pieces inside since they are clear.

NG Lavage: Indicated or Outdated?

Nasogastric lavage (NGL) seems to be a logical procedure in the evaluation of patients with suspected upper GI bleeding, but does the evidence support the logic? Most studies state that endoscopy should occur within 24 hours of presentation, but the optimal timing within the first 24 hours is unclear. Rebleeding is the greatest predictor of mortality, and these patients benefit from aggressive, early endoscopic hemostatic therapy and/or surgery. So what are the arguments for and against NGL?

Hospital admissions for chest pain often incur costly and resource-intensive workups for ACS. Is there a way to identify a low risk group who can be discharged home in a timely manner, without further workup, and without short-term adverse events from ACS?

With Dr. Jeff Tabas giving a lecture on the perennially hot topic of pulmonary embolism (PE) at the upcoming UCSF High Risk EM Conference (main link, PDF Brochure) in San Francisco May 22-24, 2013, I thought I would get a sneak peek into his discussion points.

Is ATLS wrong about palpable blood pressure estimates?

In Advanced Trauma Life Support (ATLS), we learned that a carotid, femoral, and radial pulse correlates to a certain systolic blood pressure (SBP) in hypotensive trauma patients. Specifically ATLS stated:

Carotid pulse only = SBP 60 – 70 mmHg
Carotid & Femoral pulse only = SBP 70 – 80 mmHg
Radial pulse present = SBP >80 mmHg

Chest Pain: What is the Value of a Good History?

Every year there are 6 million visits to the Emergency Department (ED) for chest pain, and approximately 2 million hospital admissions each year.¹ This is approximately about 10% of ED visits and 25% of hospital admissions with 85% of these admissions receiving a diagnosis of a non-ischemic etiology to their chest pain (CP).² This over triage has enormous economic implications for the US health care system estimated at $8 billion in annual costs.
