Trick of the Trade: Rapid Oral Phenytoin Loading in the ED

By |Categories: Neurology, Tox & Medications, Tricks of the Trade|

A 57-year-old male (75 kg) presents to the ED after a witnessed seizure. He describes a history of seizure disorder and is prescribed phenytoin, but recently ran out. A level is sent and, not surprisingly, results as < 3 mcg/mL (negative). After a complete workup, the decision is made to ‘load’ him with phenytoin 1 gm and discharge him with a prescription to resume phenytoin. An IV was not placed. Can you rapidly load him orally? [+]

Chest Pain: Coronary CT Angiography in the ED

By |Categories: Cardiovascular, Radiology|

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

By |Categories: Ophthalmology, Tricks of the Trade|

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NG Lavage: Indicated or Outdated?

By |Categories: Gastrointestinal|

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? [+]

Rivaroxaban for Pulmonary Embolism: One pill and done?

By |Categories: Cardiovascular, Pulmonary, Tox & Medications|

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?

By |Categories: Trauma|

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?

By |Categories: Cardiovascular|

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.

Mythbuster: No Maximum Dose of Enoxaparin

By |Categories: Tox & Medications|

Venous thromboembolism (VTE) is often treated with low molecular weight heparins (LMWH) such as enoxaparin. For patients with normal renal function, dosing is as follows: Enoxaparin: 1 mg/kg subcutaneously every 12 hours, or 1.5 mg/kg every 24 hours Dalteparin 200 IU/kg subcutaneously once daily Tinzaparin: 175 IU/kg subcutaneously once daily What about the obese patient? Is there a maximum dose for enoxaparin?

  • Pelvic Speculum

Trick of the Trade: No pelvic bed? No problem

By |Categories: Ob/Gyn, Tricks of the Trade|

Often finding a pelvic examination bed for a female patient needing a speculum exam can be challenging. Without the elevated foot stirrups, the bed under the patient’s buttocks obstructs the pelvic speculum handle so that it can’t rotate completely into a 6 o’clock position. Some people place an upside-down bed pan to elevate the patient’s buttocks slightly in order to create more space for the speculum. Not only is the position uncomfortable for the patient, it seems a waste of a perfectly good bed pan. Fortunately there is an alternative approach. [+]
