**Emergency Medical Minute**

Our near daily podcasts move quickly to reflect current events, are inspired by real patient care, and speak to the true nature of what it’s like to work in the Emergency Room or Pre-Hospital Setting. Each medical minute is recorded in a real emergency department, by the emergency physician or clinical pharmacist on duty – the ER is our studio and everything is live.

Podcast #209: Rabbit Done Died May 26, 2017

Show notes

Author: Sam Killian, M.D.

Educational Pearls:

"The Rabbit Has Died" is a lesser used phrase to denote finding out one is pregnant.
During a test used in the 1930s, the "Rabbit's Test," a rabbit was injected with a potentially pregnant woman's urine. If the woman was pregnant, the rabbit would begin displaying signs of pregnancy itself.
This test required killing the rabbits to visualize the ovaries, hence the term "Rabbit Done Died".

Podcast #208: Vocal Cord Dysfunction May 24, 2017

Show notes

Author: Martin O'Bryan M.D.

Educational Pearls:

Vocal cord dysfunction can mimic other causes of stridor, such as asthma and upper airway obstruction.
Patients are often very anxious because of the difficulty of inspiration.
The definitive diagnosis is laryngoscopy that must be done by a pulmonologist.
The treatment is general reassurance, asthma medications will not help. CPAP and heliox can be used to help with the stridor.
Benzodiazepines can be used to reduce the associated anxiety.

Podcast #207: Boxer's Fracture May 22, 2017

Show notes

Author: Sam Killian, M.D.

Educational Pearls:

Defined as fracture of neck (distal segment) of 5th metacarpal.
Intrinsic muscles of hand pull segment to palmar aspect of hand.
30 degrees of angulation is allowed. Any more increases risk of chronic pain, grip strength and grasping deficits, and rotational deformities.
Reduce fracture if more than 30 degrees of angulation or if rotation is present.
Splint fracture in "ulnar gutter" with goal being flexion at MCP and extension at DIP and PIP.

Podcast #206: Urethral Injuries May 20, 2017

Show notes

Author: Jared Scott, M.D.

Educational Pearls:

DDx for blood at urethral meatus includes: pelvic fracture, ruptured bladder, kidney laceration, penile trauma.
Retrograde Urethrogram (RUG) must be performed before placing foley and is critical for diagnosis.

Podcast #205: Post Cardiac Arrest Temperature Control May 18, 2017

Show notes

Author: Michael Hunt, M.D.

Educational Pearls:

Research has shown that the higher temperatures post-cardiac arrests may lead to poorer outcomes.
Initially, 33 deg C was the target temp. However, more research is being done to find therapeutic temperature levels.
New studies have shown that the cooling protocol differs for inpatient cardiac arrests vs. outpatient cardiac arrests. The results show that it may not be necessary to cool inpatient cardiac arrests.

Deep Dive #3: The New Standard in Stroke Treatment May 16, 2017

Show notes

Authors: Rebecca van Vliet MS, APN; Michelle Whaley MSN, CNS, CCNS, ANVP-VC

The Stroke Team at Swedish Medical Center gives us a taste of how they are breaking records with door-to-needle time in management of acute cerebrovascular accidents.

Podcast #204: Thoracotomy May 14, 2017

Show notes

Author: Aaron Lessen M.D.

Educational Pearls:

Thoracotomy is a potentially life-saving procedure. However, outcomes are often poor and the procedure itself poses many risks to provider and patient.

Chance of surviving a thoracotomy when there is no cardiac activity on ultrasound is 0%.

Performing a thoracotomy is unlikely to benefit patients with no cardiac activity on ultrasound or patients that lost vital signs greater than 10 minutes before starting the procedure.

A thoracotomy is maximally beneficial in patients with a penetrating chest injury that occurred less than 10 minutes before the procedure.

Podcast #203: Wine, Milk and… Vaccines!? May 12, 2017

Show notes

Author: Dave Rosenberg M.D.

Educational Pearls:

Louis Pasteur developed the technique that is now known as pasteurization. It was first used in the wine-producing regions of France, and eventually in dairy products like milk.
Pasteur also investigated infectious disease. During one experiment, Pasteur's lab assistant accidentally infected chickens with a weakened form of cholera. When none of the chickens died, Pasteur re-infected them with a stronger strain. This time, none of the chickens became sick because they had been inoculated against the disease. This experiment paved the way for modern vaccination.

Podcast #202: Tide Pods May 10, 2017

Show notes

Author: Susan Brion M.D.

Educational Pearls:

Laundry and dishwasher detergent pods resemble candy and can be ingested by children.
These tide pods are very highly concentrated and can cause chemical burns of the lips, airway, eyes, mouth and esophagus.
The strong bases in detergent pods (pH>12) can cause liquefactive necrosis, which can cause immediate perforation of the esophagus.
Common symptoms associated with ingestion of detergent pods include pain, dysphagia, drooling, mediastinal pain, upper airway inflammation. The presence or absence of symptoms does not indicate severity - suspected ingestions should be admitted and undergo bronchoscopy.
Mental status should be assessed rapidly because detergent ingestion can lead to CNS depression and aspiration.

Podcast #201: Task Interruption May 08, 2017

Show notes

Author: Mark Kozlowski M.D.

Educational Pearls:

Humans cannot "multitask" effectively - a more accurate term is "task interruption."
When doing more than one task at once, we are more likely to forget key details and perform both tasks more slowly overall.
Do not interrupt people who are focusing on critical tasks - programming a pump or drawing up doses.
Think about ways to reduce task interruption in your hospital for a better clinical practice.
