Trick of the trade: Nebulized naloxone

Overdoses of long-acting opiates, such as oxycodone and methadone, are challenging to manage, especially if these patients are chronically on opiates.

On the one hand, you want to reverse some of the sedative effectives with naloxone so that they aren’t near-apneic and hypoxic. You also want to be able to take a history from them. On the other hand, you don’t want to abruptly withdraw them with naloxone such that they become violent and agitated. It is a fine balancing act.

Long-acting opiates present a separate challenging because naloxone wears off fairly quickly in 30-45 minutes. These patients may require repeat dosings and/or a naloxone IV drip.

Paucis Verbis: Influenza – To treat or not to treat?

Influenza season typically peaks in the United States during the Jan-Feb months and can start as early as October. You can read about the 2011-12 seasonal flu data on the CDC website.

Should you give a patient with influenza an antiviral agent or just provide supportive therapy?

This Paucis Verbis card summaries the CDC’s Advisory Committee on Immunization Practices (ACIP) recommendations for this upcoming 2011-12 flu season. I also let patients with uncomplicated influenza who are going to be managed as outpatients know that a 5-day course of osteltamivir or zanamivir will cost them about $50-80. Often that sways them towards declining a prescription and “toughing out” an extra day of the flu.

G-Advising: Using Google Hangout to advise medical students

Get an advisor.

Don’t try to navigate medical school and residency on your own.

This is key especially during medical school as you try to get through and around the mounds of reading, paperwork, options, and pitfalls. If you are interested in Emergency Medicine (EM) as a career, that means getting one or several great EM advisors. Don’t rely on non-EM faculty to give you any insight into EM. Inevitably, I have found that they give incomplete or slightly skewed perspectives about the pros and cons of EM.

Trick of the Trade: Nasal cannula oxygenation during endotracheal intubation

You are managing a 300-pound patient with a long history of severe COPD, who now requires intubation because of a pneumonia and COPD exacerbation. You anticipate that the patient may be a difficult airway intubation and may desaturate quickly during laryngoscopy. While you are setting up to orotracheally intubate this patient, you preoxygenate this patient as best as you can with a non-rebreather mask.

What can you do to prolong the patient’s time-to-desaturation so that you aren’t as rushed to place the endotracheal tube?

Paucis Verbis: Ventilator settings for obstructive lung disease

Following up with last week’s Paucis Verbis card on Ventilator Settings for Acute Lung Injury and ARDS, here is the card on Ventilator Settings for Obstructive Lung Disease. This is for patients who present with acute asthma or COPD exacerbation who require endotracheal intubation.

What initial ventilator settings should you set for these patients?

Go to ALiEM (PV) Cards for more resources.

Thanks to Dr. Jenny Wilson for the card and Dr. Scott Weingart for the original stellar podcast from which this card was derived.

Paucis Verbis: Ventilator settings for acute lung injury and ARDS

A patient presents with severe multilobar pneumonia and refractory hypoxia requiring endotracheal intubation. The respiratory therapist connects your patient to the ventilator.

“What settings would you like your patient on?”

Back in 2010, Dr. Scott Weingart posted a great podcast on “Dominating the Vent“. It’s such a fantastic distillation of the practical aspect of ventilator setting management of all intubated patients except those with an acute asthma or COPD exacerbation, Dr. Jenny Wilson and I thought this would be a great Paucis Verbis card to have in your peripheral brain.

Note: The tidal volume should be calculated based on Predicted Body Weight (PBW), which is based on patient gender and height. The calculation is at the bottom of the card. Using a patient’s actual weight might yield a tidal volume that is way too high. The initial vent settings in the example box are for a patient with a PBW of 70 kg. That’s basically a 5’9″ man or 5’11” woman.

Trick of the trade: Quieting the shaky EKG tracing

A patient with Parkinson’s disease presents with chest pain to your ED. Her tremors prevent you from getting a good quality EKG because of the movement artifact.
