ASA Toxicity

The learner will be presented with an altered febrile patient, requiring an initial broad work-up and management plan. The learner will receive a critical VBG report of severe acidosis, hypoglycemia and hypokalemia, requiring management. Following this, the rest of the blood work and investigations will come back, giving the diagnosis of salicylate overdose. The patient’s mental status will continue to decline and learners should proceed to intubate the patient, anticipating issues given the acid-base status. The learner should also initiate urinary alkalinization and make arrangements for urgent dialysis.

Newborn Sepsis with Apneas

A 3-day-old term male infant is brought to the ED by EMS after being seen at their Family Physician’s office with a low temperature (33.1oC). The child has been feeding poorly for about 12 hours, and has vomited twice. He is lethargic on examination and poorly perfused with intermittent apneas lasting ~ 20 seconds. He requires immediate fluid resuscitation and broad-spectrum antibiotics. His perfusion will improve after IVF boluses, however the apneas will persist and necessitate intubation.

Pediatric Septic Shock

A 4 year-old girl is brought to the ED because she is “not herself.” She has had 3 days of fever and cough and is previously healthy. She looks toxic on arrival with delayed capillary refill, a glazed stare, tachypnea and tachycardia. The team will be unable to obtain IV access and will need to insert an IO. Once they have access, they will need to resuscitate by pushing fluids. If they do not, the patient’s BP will drop. If a cap sugar is not checked, the patient will seize. The patient will remain listless after fluid resuscitation and will require intubation.

Adrenal Crisis

A 46-year-old female presents to the ED complaining of fatigue, anorexia, and weight loss over the last two weeks. She had the “stomach flu” a couple weeks ago and thought she was getting over it. But now she feels very weak and seems to be vomiting again. On presentation, the patient will have mild hypothermia, hypoglycemia, and hypotension. The team will have to initiate fluid resuscitation and an initial workup. The patient’s blood pressure won’t respond to 4 L of IV fluids, forcing the residents to work through the differential diagnosis of shock. Eventually, they will receive critical VBG results that indicate a mild metabolic acidosis, hyperkalemia, and hyponatremia. The team will need to treat the hyperkalemia and initiate hydrocortisone therapy.

Coarctation of the Aorta

A 2-week-old neonate presents in shock requiring the learner to implement an initial broad work-up. The patient will also be hypoglycemic, and will seize if this is not promptly recognized. Physical exam and CXR findings will suggest coarctation of the aorta as the likely cause, and the learner should recognize the need for gentle fluid boluses and a prostaglandin infusion. Unless learners anticipate appropriately and intubate the patient prior to beginning the prostaglandins, the infant will become apneic after starting the infusion and require intubation.

Multi-trauma case: burn and head injury

The case will begin with the arrival of patient from a house fire who has 30%TBSA burns. The team will be expected to recognize the need for intubation and fluid resuscitation. After successful intubation, a second patient will arrive from an altercation outside a bar. He appears to have a blunt traumatic head injury after being repeatedly kicked. The team is expected to recognize hypoglycemia in the context of a minor head injury and provide immediate glucose replacement. During the management of the head injured patient, the burn patient will continue to by hypotensive. The team will need to recognize the possibility of CN toxicity. The patient will also become more difficult to ventilate and will require an escharotomy.
