What the hell is a Lyceum?

The Reality

Clinical shifts, especially in most over-extended academic EM centers, are chaotic

The practice of EM varies widely from hospital to hospital, and even attending to attending within a residency program

The balance of education versus service can feel skewed for residents

Page 9: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

The Goal

Incorporate evidence-based teaching and nuanced academic debate into the clinical environment

Ensure uniform resident exposure to this, even if “off-service” that month

Promote relevant, enjoyable, and succinct faculty teaching during shifts

Page 10: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

The Curriculum

Developed in collaboration between residents and faculty at Bellevue/NYU Hospital Center

Controversial topics in EM chosen

Can be used to start resident-initiated debate, as a background for mini-lectures, or as a stand-alone lesson plan.

Curriculum Logistics

Curriculum team discusses potential topics and questions, reviewing the literature for areas of practice variation or deviation from evidence-based practice

New Topic Roll Out – 1st Wednesday of the month

Questions and key articles sent to attendings the Sunday before

Page 12: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

Curriculum Logistics

Posters placed in all clinical areas

Residents encouraged to discuss questions with attendings, empowering and enlisting them to pilot their own education

POSTERS

Acute Coronary Syndrome1. What anti-coagulants and/or anti-platelet agents do

you use in a patient with a STEMI? In an NSTEMI?

2. How do you identify and manage patients with unstable angina?

3. How do you risk stratify patients with chest pain? Do you use any clinical decision rules?

4. How reassuring is a recent (< 1 year) negative stress test in managing a patient with chest pain? How about a recent “normal” cath (i.e., < 30% blockage, no intervention)?

Page 15: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

Hyperkalemia1. What are the EKG changes associated with

hyperkalemia? Do these changes occur in a predictable order?

2. What is the role of kayexylate in the treatment of hyperkalemia?

3. Is there a threshold serum potassium level or EKG finding that triggers you to administer calcium? How do you give calcium when you use it?

4. When do you re-dose patients after treating them for hyperkalemia?

Page 16: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

“ANSWERS”

Page 17: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

“Answers”

Look for as much high quality evidence as we can find

Create “answers” based on the best evidence and group consensus

Where there is minimal evidence, we use expert opinion

Distributed via email and in conference

Page 18: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

What is the role of Kayexalate in the treatment of hyperkalemia?

Kayexalate (Sodium Polystyrene Sulfate) is a cation-exchange resin that was approved in 1958 as a treatment for hyperkalemia. It is believed to help exchange sodium for potassium in the colon and thus encourage excretion of potassium from the body.

Although this drug has been used for a number of years as an adjunct to more acute treatments, there are two potential problems with its use.

Page 19: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

What is the role of Kayexalate in the treatment of hyperkalemia?

Firstly, there is little to no evidence that Kayexalate effectively reduces serum potassium levels. The two original studies promoting its use, often cited in literature, were published in the New England Journal of Medicine in 1961. These two trials were completed without any controls, multiple confounding variables, a lack of statistical analysis, and demonstrated minimal if any effect of Kayexalate on serum potassium levels (Scherr, 1961 & Flinn 1961).

Furthermore, a recent study in 1998 also failed to demonstrate a statistically significant difference in serum potassium levels at 4, 8, and 12 hours after administration of 30g Kayexalate with sorbitol, compared to controls (Gruy-Kapral, 1998).

Discuss the Utility of Pretreatment Agents in RSI.

Atropine: This drug is most commonly used in pediatric patients (particularly < 2 years of age) to attenuate reflex bradycardia associated with succinycholine administration in RSI.  The idea is that kids tolerate tachycardia very well but do poorly with bradycardia.  The dose of atropine for pretreatment is 0.01 mg/kg IV (minimum dose is 0.1 mg).

Although it continues to be recommended, randomized control trials have shown no difference in the rate of bradycardia in pediatric patients receiving succinycholine whether they got atropine or not (McAuliffe, 1995).  Most airway "gurus" have dropped atropine as a recommendation for pretreatment but suggest having it at the bedside in case bradycardia occurs. 

Page 21: Whitney K. Bryant , MD, MPH Anand Swaminathan , MD, MPH

Discuss the Utility of Pretreatment Agents in RSI.

Fentanyl: Fentanyl pretreatment is thought to attenuate the sympathetic response to direct laryngoscopy.  This sympathetic response can drive up heart rate and blood pressure and so may be detrimental to patients, especially those patients with ischemic heart disease, aortic dissections etc.  

The dose required for full attenuation is 11 - 15 mcg/kg but this large a dose may cause significant hypertension.  Doses as low as 2-3 mcg/kg will produce some attenuation and are more reasonable for RSI purposes.

Important to note that the use of opioids in pretreatment for head trauma is an area of controversy.  The Walls text recommends it, but be aware there is some evidence to suggest that it may increase ICP in patients with head injury (de Nadal, 1998).

Discuss the Utility of Pretreatment Agents in RSI.

Lidocaine: Lidocaine pretreatment is also believed to attenuate the response to direct laryngoscopy but instead of sympathetic response the response is bronchoconstriction and increased intracranial pressure.  

The evidence for this is incomplete at best, but many argue there is little downside to a dose of lidocaine in this situation. A 2001 literature review by Robinson and Clancy found no evidence that pretreatment with lidocaine in patients with head injury undergoing RSI improved neurological outcomes.

The dose for both reactive airway disease and increased ICP is 1.5 mg/kg IV.

Future Directions

Involvement of non-Bellevue residents and attendings in topic development

Creation of blog/chat on a regular basis to discuss/debate topics remotely

Development of strategy to analyze impact of topics on actual management
