A time-based approach to elderly patients with altered mental status
It’s 7 am on a Monday. Your first patient is an 82 year-old woman who was brought in by EMS from an assisted living facility. All EMS can tell you is that she was not acting herself. You enter her room and introduce yourself. “Hello Mrs. Jones. How are you today?” The woman startles, “Well, you see, I went to put my dog out, and then I was just walking, and couldn’t remember. So it’s all coming full circle, and then I ate a sandwich.” Just then EMS rolls in with another patient, a 75 year-old male coming from home, who was found by his wife in his recliner minimally responsive, with a GCS of 6. He is followed by a 76 year-old female who had a fall from standing three days ago, and has been increasingly confused today, and is currently oriented only to person.
Airway management is one of the defining skills of an emergency physician, but our role in the care of intubated patients may continue long after endotracheal tube placement is confirmed. In mechanically ventilated patients, acute elevations in airways pressures can be triggered by both benign and life-threatening causes. When the ventilator alarms, do you know how to tell the difference? What is your approach in troubleshooting the potential problems?
Differentiating between SVT with aberrancy and VT can be very difficult. It is crucial to be able to make this distinction as therapeutic decisions are anchored to this differentiation. Brugada et al prospectively analyzed 384 patients with VT and 170 patients with SVT with aberrant conduction to see if it was possible to come up with a simple criteria to help differentiate between the two with high sensitivity and specificity.
