Trick of the Trade: Opioids for air hunger

BipapA patient presents with significant shortness of breath from a COPD exacerbation. His room air saturation is 80%, respiratory rate of 30, and is uncomfortably seated in a tripod position. You administer the usual regimen:

  • Oxygen by face mask
  • Nebulized albuterol and atrovent
  • Solumedrol
  • Bipap
  • Set up for possible intubation

With the Bipap mask on, the patient’s subjective sense of dyspnea and “air hunger” seems to make it harder for him to tolerate the tight-fitting mask.

Trick of the Trade: Needlestick hotline 888-448-4911

NeedlstickGlove

You are a fourth-year medical student and super-excited to be doing your first supervised central line procedure on an actual patient. You have done so many central lines on mannequins and simulations. You feel ready. In your excitement, however, you stick yourself with the 22 gauge finder needle after you successfully get a flash-back of the patient’s venous blood.

After handing off the procedure to your senior resident, you go into a mild panic. Your patient is a known HIV patient with an unknown CD4 count and viral load. After taking off your gloves and washing your hands, you report this to the attending.

Should you start post-exposure prophylaxis medications for HIV? You remember that if post-exposure HIV medications are recommended, you should start it immediately and definitely within 2 hours of exposure.

It’s difficult to concentrate when faced with so many questions whirling in your mind.

Paucis Verbis: Does this DM leg ulcer have osteomyelitis?

diabetic foot ulcer

We sometimes see diabetic patients in the ED for a worsening foot ulcer. Sometimes it’s the chief complaint. Other times, however, you just notice it on physical exam. So, be sure you examine the feet of your diabetic patients. Occasionally, you’ll be surprised by what you find.

Several questions come up with diabetic foot ulcers:

  • Is it a true diabetic foot ulcer, or is it an arterial or venous insufficiency ulcer?
  • Is there underlying osteomyelitis?
  • How can I best diagnostically work this foot ulcer up for osteomyelitis?
  • What is the Wagner grade of this ulcer? (I think it’d be Grade 2.)

Thanks to JAMA‘s Clinical Rational Examination series, there is a systematic review of diabetic leg ulcers and osteomyelitis. Here are the highlights:

Trick of the Trade: Pediatric ear exam

ChildEaraches2

Performing a physical exam on frightened pediatric patients can often be challenging. I am always thrilled to add more child-whisperer techniques to my arsenal of tricks. I have written in the past about:

Paucis Verbis: Legionella pneumonia

Legionella Infection

Did you know that there was an unexplained spike in Legionnaire’s disease (pneumonia caused by Legionella pneumophila) during the 2009 H1N1 flu pandemic?

Since the flu season is rapidly approaching, I thought I would review what Legionnaire’s disease looks like. Yes, they will have a fever, cough, and pneumonia on CXR. These patients are generally pretty sick and almost always need hospitalization. What makes it unique? The trick is to look for extrapulmonary findings, which help to distinguish it from other atypical pneumonias. Relative bradycardia is a sure tip.

Why do we want to differentiate it from other pneumonias? Legionnaire’s disease requires reporting to your state’s health department to help track for outbreaks.

Paucis Verbis: Distracting injuries in c-spine injuries

Cervical spine assessment distracting injuries

“Distracting injury” is a frequent cited reason for imaging the cervical spine in blunt trauma patients, per the NEXUS study. In the Journal of Trauma in 2005 and 2011, studies aimed to narrow the definition of “distracting injury”. Although both are studies at different sites, both conclude the same:

  • Chest injuries may be considered “distracting injuries” because of their proximity to the cervical spine.

Example

So let’s say you are caring for a non-intoxicated motor vehicle crash patient with an isolated tibia fracture (i.e. a “long bone fracture”), no chest injuries, and no neck pain/tenderness. Per the NEXUS criteria, you might consider this patient to have a “distracting injury” because of the long bone fracture. Instead, the literature now supports your clinically clearing the cervical spine without imaging.

Wait, let’s rethink this. Does this mean that you should get cervical spine imaging for ALL blunt trauma patients with ANY chest wall tenderness?! NO. That’s just crazy. You should still factor in the mechanism of injury, severity of pain, and your clinical gestalt.

So for me, these “distracting injury” studies are helpful such that:

  • If your trauma patient does NOT have chest trauma, it may help you avoid unnecessary cervical spine imaging, as suggested by the NEXUS criteria.
  • If your trauma patient DOES have significant chest trauma, I have a lower threshold to obtain cervical spine imaging despite the neck being non-tender.
