Opioids are amazingly effective for pain control. Patients on chronic opioids, however, often struggle with constipation. These patients may fail supportive treatment with enemas and laxatives.
Let’s be honest. When was the last time results from urine drug screens (UDS) changed your management plan? Many times it takes hours for the patient to give the urine sample anyway. And, with all of the false positives out there, how do we know what the heck the result is actually telling us?
I find it amazing that I know more non-emergency physicians virtually in the social media world rather than in person. Primarily through Twitter, I follow and am followed by medical educators from various specialties. If you haven’t joined Twitter yet, I think it might be time. There is a whole world of collaboration and conversation going on in this virtual community, which crosses specialties and geography.
Last week, Dr. Javier Benítez (@jvrbntz) was tweeting a Question of the Day, referencing a 2010 Paucis Verbis card on overanticoagulation, which was based on the 2008 American College of Chest Physicians (ACCP) guidelines. About 8 minutes after I retweeted his question, Dr. Roy Arnold (@cholerajoe), a pulmonary/critical care physician kindly informed me that the 2012 ACCP guidelines have been out since February.
So this PV card is replacing the 2010 card with revised recommendations. For more in-depth discussion, definitely take a look at Dr. Scott Weingart’s great podcast over at EMCrit. He helps to clarify holes which the 2012 ACCP guidelines don’t really address such as:
What if the patient is minorly bleeding with a high INR?
What if you only have the 3-factor PCC (factors II, IX, X) and not the recommended 4-factor PCC (factors II, IX, X plus factor VII)?

To give or not to give a cephalosporin in penicillin-allergic patients?
I remember back to my days in pharmacy school when I learned that there was approximately a 10% risk of cross-reactivity, if a cephalosporin was given to a penicillin-allergic patient. They probably said something about the risk being less with 3rd and 4th generations cephalosporins, but lets be honest… who remembers anything but that magic 10%? When I started working more with physicians, I found that they also learned the same 10% rule in medical school. Well, I guess that means it’s fact, right? Not so fast!
Medication error is something that we all fear in Emergency Medicine and do our best to avoid. Here’s a scenario and simple approach for you, provided by Zlatan Coralic, PharmD (Assistant Clinical Professor in the UCSF School of Pharmacy).
You are an emergency physician working in an underserved country. You are presented with an asthmatic kid with severe retractions and tight wheezes. Multiple nebulizers and corticosteroids have failed. You want to try some magnesium sulfate before risking intubation in a place with no reliable access to ventilator equipment. You know the dose should be 1 gm IV over 20 minutes.
Continuing on the theme of Toxic Alcohols (osmolal gap, ethylene glycol, methanol), this Paucis Verbis card focuses on isopropyl alcohol toxicity, which is commonly found in rubbing alcohols. In this toxic alcohol, fomipezole is actually NOT indicated because you want to have alcohol dehydrogenase convert the toxic parent compound (isopropyl alcohol) into the nontoxic metabolite (acetone).
Note that these are merely guidelines and you should tailor management plans with your toxicologist and nephrologist.
