Trick of the Trade: Check pupillary constriction with ultrasound

By |Categories: Ophthalmology, Tricks of the Trade, Ultrasound|

In some trauma patients with head and face trauma, you will need to check their pupillary response to light. Severe periorbital and eyelid swelling, however, make this difficult. You want to minimize multiple attempts to retract the eyelids because of the risk of a ruptured globe. What’s a minimally painful and traumatic way to check for pupillary constriction? [+]

Paucis Verbis: Post-exposure prophylaxis (non-occupational)

By |Categories: ALiEM Cards, Infectious Disease|

You know how chief complaints present to the ED in multiples? In one week, I had several cases where patients were asking for post-exposure prophylaxis treatment NOT in the content of a sexual assault. I haven't had to manage such cases in a long time and so needed to look up the recent guidelines from the CDC.1 The trick is not to forget about all the co-existing problems and infections beyond just HIV. Specifically, don't forget about gonorrhea, chlamydia, and trichomonas. PV Card: Post-Exposure Prophylaxis for Non-Occupational Contact  Adapted from [2] Go to ALiEM (PV) Cards for more resources.

Trick of the Trade: Steristrip-suture combo for thin skin lacerations

By |Categories: Geriatrics, Trauma, Tricks of the Trade|Tags: |

Lacerations of elderly patients or chronic corticosteroid users can be a challenge because they often have very thin skin. Sutures can tear through the fragile skin. Tissue adhesives may not adequately close the typically irregularly-edged laceration. How do you repair these lacerations? Do you just slap a band-aid on it? [+]

  • Sedatives

Paucis Verbis: Chemical sedation for severe agitation

By |Categories: ALiEM Cards, Tox & Medications|

Haldol, Ativan, and Versed... oh my. In the Emergency Department, some patients present very acutely and aggressively agitated. This is usually the result of illicit drug use or a schizophrenic who hasn't been taking medications (or both!). Fortunately, we have an arsenal of medications to help sedate the patient. One study looked to answer the question of what single IM sedation agent is most effective, as measured by the shortest time to sedation and time to arousal.

Trick of the Trade: Benzoin for opening traumatic, swollen eyelids

By |Categories: Ophthalmology, Tricks of the Trade|Tags: |

Patients who sustain facial trauma often have swollen eyelids. They may be so swollen that it is impossible to pull back the eyelids for an ocular exam. You use one of our “Tricks of the Trade”ideas and attempt to “roll” the upper eyelid using the Q-tip trick (above).Fresh blood on the face, however, makes the Q-tip a little slippery along the upper eyelid, preventing an adequate view of the eye itself.

By |Categories: ALiEM Cards, Gastrointestinal|

You have a 40 year-old man who presents to the ED for persistent right upper quadrant abdominal pain for 12 hours after eating a fatty meal. He has no fevers, nausea, flank pain, or dysuria. His physical exam shows no fever and only moderate tenderness in the RUQ without guarding. He has a Murphy's sign which is improved after a total of 8 mg of IV morphine. His laboratory results, which include a WBC, liver function tests, lipase, and urinalysis, are normal. Can you safely say that the patient doesn't have cholecystitis?

Paucis Verbis: Right and posterior ECG leads

By |Categories: ALiEM Cards, ECG|

A standard 12-lead ECG can be very telling for patients with chest pain or shortness of breath. A right ventricular (RV) and posterior wall infarct, however, can present very subtly. You can obtain special right-sided (V1R-V6R) and posterior leads (V7-V9), if you are concerned. What are the indications for obtaining right-sided and posterior ECG leads?  Go to the ALiEM Cards for more resources. Addendum 3/11/11: Right sided ECG leads (V1R-V6R) are positioned in a mirror image fashion from the standard 12-lead precordial leads. Posterior ECG leads (V7-V9) are applied by moving V4-V6 in the posterior positions.
