The Alcoholic Patient in the ED
Well, we have all been there....EMS rolls in with "another drunk guy" found down in the street. The nurses tell you, "he is here all the time...he is just drunk." You should be scared any time you hear this phrase uttered. Always be a little nervous about this group of patients and you won't fall victim to many of the pitfalls that some of us have experienced.

T-wave inversions are commonly found in many conditions other than ACS. Many pulmonary conditions, elevated intracranial pressure, LVH, bundle branch block, and young age are associated with T-wave inversions.
T-wave inversions are especially notable in patients with pulmonary embolism, and one study identified a key difference in T-wave inversion patterns in PE vs. ACS: T-wave inversions in leads III and V1 simultaneously were far more likely to be assocaite with PE, whereas the presence of T-wave inversions in I and aVL were almost always ACS.
A key takeaway point is to maintain a broad differential even in the presence of T-wave inversions...it's not necessarily just ACS!

Manibular Dislocations:
Some authors also recommend using rolled guaze to hold the patient's mouth shut so that they do not inadvertantly dislocate their jaw a second time if they happen to yawn while awakening from their sedation.

Patients who present to the ED with an elevated INR due to vitamin K antagonists many times do not need to be reversed. Simply holding a dose is all that is usually necessary for patients with an INR < 9. Fortunately, guidelines published in CHEST are available to help guide management.

Whereas only 6% of young patients with PE present with syncope, 15-20% of elderly patients with PE present with syncope. The simple takeaway point is that whenever an elderly patient presents with syncope, always strongly consider the possibility of PE, even though they may lack classic pleuritic chest pain.

With few exceptions, always assume that elderly patients presenting to the ED with an acute illness are very dehydrated. Here are a few reasons why the elderly patient, even on a normal day, may be mildly dehydrated:
1. The elderly have been shown to have decreased total body water.
2. The elderly have a decreased thirst response.
3. The elderly have a decreased renal vasopressin response.
Given these issues, when an elderly patient develops a systemic illness (especially pulmonary process), they lose even more fluid via insensible losses. By the time they arrive in the ED, unless they are presenting because of overt pulmonary edema, they almost always will benefit from generous IV fluid administration.

Nursemaid Elbow:
It is typically taught that the way to reduce a nursemaid's elbow is to hold the elbow at 90 degrees, then firmly supinate and flex the elbow. Place your thumb over the radial head and apply pressure as you supinate.(Taken from Sean Fox's Pearl on 7/20/2007)
However, there is a growing body of evidence that is showing that hyperpronating the forearm actually has a higher success rate on first attempt, is easier to perform, and is associated with less pain then supinating the forearm. The overall reducation rates where similar for both methods.
The hyperpronation method consists of hyperpronating the forearm and then flexing the elbow. Since the child tends to already hold their arm in partial pronation, the hyperpronation technique tends to need less force and has been associated with less pain.

Transvenous pacing
We had a very interesting case the other day in the ED. A 60 yo male presented after a syncopal episode. After arriving in the ED he was awake (with a pulse of 50) but then became asystolic, without warning. He then woke up and 10 minutes later became asystolic again. He then woke up again. So, we decided to put in a transvenous pacer.
Some considerations when putting in a transvenous pacer:
