Multi-trauma (Kicked off a Horse)

This case is written by Dr. Kyla Caners. She is a staff emergency physician in Hamilton, Ontario and the Simulation Director of McMaster University’s FRCP-EM program. She is also one of the Editors-in-Chief here at EmSimCases.

Why it Matters

Management of trauma patients with multiple intercurrent injuries can be challenging. This case provides an opportunity for junior learners to stretch themselves beyond their comfort zones. In particular, this case highlights the following:

  • The need for a systematic approach to the initial assessment and ongoing re-assessment of any complex trauma patient
  • The importance of prioritizing tasks and adjusting priorities as patient status changes
  • The complexity of managing a hypotensive, head-injured patient

Clinical Vignette

A 32-year-old female presents as a trauma activation with EMS after being bucked off of her horse. Her mom witnessed the episode and called EMS because she seemed groggy. She has had a low BP with EMS on route. Her current BP is 80/40.

Case Summary

A 32-year-old female presents after being bucked off of her horse. She is brought in as a trauma team activation because of a low BP. Her primary survey will reveal a boggy hematoma over her right temporal area as well as an unstable pelvis. Her initial GCS will be 8. The team will proceed through airway management in a hypotensive, head-injured trauma patient while also binding her pelvis. The patient eventually shows signs of brain herniation, which the team will need to manage prior to consultant arrival.

Status Epilepticus

This case is written by Dr. Donika Orlich. She is a PGY5 Emergency Medicine resident at McMaster University who also completed a fellowship in simulation and medical education last year.

Why it Matters

This case is an excellent review of the management of status epilepticus and includes 2nd, 3rd, and 4th line agents for treatment. This case also highlights a few unique practice challenges, including:

  • The hemodynamic effects of administering phenytoin too quickly
  • Disclosing medical error to families
  • Special agents to be considered in refractory seizure, such as magnesium sulfate, hypertonic saline, and pyridoxine

Clinical Vignette

A 38 year-old female is brought in by EMS with active seizure. She was last seen normal about 45 minutes ago by her husband, and has been witnessed seizing now for about 20 minutes. She is known to have epilepsy. EMS have 1 line in place, and 5mg IV midazolam was given en route.

Case Summary

A 38 year-old female presents actively seizing with EMS. She will fail to respond to repeat doses of IV benzodiazepines, and will require escalating medial management. Following phenytoin infusion, the patient will become hypotensive (because the phenytoin was given as a “push dose”, which the nurse will mention). The patient will then stop her GTC seizure, but will remain unresponsive with eye deviation. The team should recognize this as subclinical status, and proceed to intubate the patient.   The patient will continue to seize following phenobarbital and propofol infusion. Urgent consults to radiology and ICU should be made to expedite care out of the ED. The team will be expected to debrief the phenytoin medication error and disclose the error to the husband.

Altered LOC

This case was written by Dr. Kyla Caners. She is a PGY5 Emergency Medicine resident at McMaster University and is also one of the Editors-in-Chief here at EMSimCases.

Why it Matters

It’s easy as a simulation case writer to get excited about complex cases with rare presentations. But it’s also important to remember to teach to the level of the resident. This case highlights some very important lessons for junior learners:

  • The importance of a broad differential diagnosis in the altered patient
  • How to prioritize and coordinate an extensive work-up for a relatively ill patient
  • Recognizing when an altered patient needs to be intubated

We take these skills for granted as experienced clinicians. But it’s amazing how many excellent teaching conversations come from running this very simple case.

Case Summary

An 82 year old man arrives to the ED by EMS with a GCS of 7. He smells of urine and feces, and apparently has not been seen in 4 days. He is hypotensive and tachycardic. With simple fluid resuscitation (1-2L), the BP will improve. Learners are to organize a broad diagnostic work-up and coverage with broad-spectrum antibiotics. They must also recognize the need to intubate. If they do not, the patient will vomit and have a resultant desaturation. The case ends after successful workup and intubation.

Clinical Vignette

You are working in a community ED. Mr. Alito Bizzaro is brought in by EMS into a resuscitation room with altered LOC. He is known to be reclusive, but always picks up his paper at 10am. His neighbours had not seen him pick up his paper in 4 days, and so they called. The patient was found on the floor in his apartment near the doorway to the bathroom. He is 82 years old and lives alone. His apartment was unkempt. The patient is covered in urine and feces.

Subarachnoid Hemorrhage with Increased Intracranial Pressure

This case was written by Dr. Martin Kuuskne from McGill University. Dr. Kuuskne is a PGY4 Emergency Medicine resident and one of the editors-in-chief at EMSimCases.

Why it Matters

This case highlights three important aspects of the management of a subarachnoid hemorrhage:

  • Blood pressure control in an undifferentiated neurologic catastrophe
  • Safe approaches to intubating a patient with possible acute hydrocephalus
  • Management of a patient demonstrating signs of increased intracranial pressure

Clinical Vignette

You are working an evening shift at a tertiary care centre emergency department with full surgical capabilities. A patient is brought into the resuscitation area by ambulance with decreased mental status. The patient was at the gym lifting weights; he complained of an acute headache to his friend and suddenly fell to the ground. The patient remained unconscious with sonorous breathing. The ambulance was called.

Case Summary

A 45-year-old male who suffered an aneurysmal subarachnoid hemorrhage while weightlifting presents to the emergency department requiring intubation for airway protection and develops acute hydrocephalus requiring ICP lowering maneuvers before definitive surgical management.
