Your next patient has heavy dysfunctional uterine bleeding (DUB). She is tachycardic and pre-syncopal. While you establish an IV, resuscitate her, and wait for the gynaecology team to arrive, is there any trick you can use to stem the bleeding?
Ectopic pregnancies account for as many as 18% of patients who present with first-trimester bleeding or abdominal pain in the Emergency Department. This Paucis Verbis card summarizes the 2008 American College of Obstetricians and Gynecologists (ACOG) guidelines on the use of methotrexate (MTX) for ectopic pregnancies. Not all ectopic pregnancies require operative management.
What are the indications and contraindications to MTX? When should they follow up with their obstetrician?
Answer: In 4 days for a repeat b-HCG and possible second dose of MTX
Note that one of the eligibility criteria is that the patient must have an “unruptured ectopic pregnancy”. Many would consider that any ultrasonographic evidence of free fluid may be a sign of an early rupture. It is left up to clinician judgment in how “unruptured” is interpreted.

Who loves relocating shoulder dislocations as much as I do? I know you do.
Often patients undergo procedural sedation in order to achieve adequate pain control and muscle relaxation. Alternatively or adjunctively, you can inject the shoulder joint with an anesthetic. Personally, I have had variable effectiveness with this technique. In cases of inadequate pain control, I always wonder if I was actually in the joint.
How can you improve your success rate in injecting into glenohumeral joint injection?
Did you know that the American Association of Poison Control Centers reports that 10% of poison center calls are related to acetaminophen ingestions? That’s a lot. This Paucis Verbis card reviews the basics of acetaminophen toxicity. I included the Rumack Matthew nomogram to help you plot out the patient’s risk for hepatotoxicity.
In the Emergency Department, we often screen for acetaminophen toxicity for patients who may have ingested substances as a suicide attempt. We check the serum acetaminophen level 4 hours post-ingestion. Occasionally, we are surprised by a toxic level because in the first 24 hours, because symptoms are can be mild and nonspecific (abdominal pain, nausea, lethargy).

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.
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.

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.
