Quick answer
How should I present an anaphylaxis case on rounds?
This is one of the presentations that should be shorter than usual: state the trigger, the multi-system findings, and that epinephrine is being given now, before a full history. Give vitals to show the severity. Do not lead with antihistamines or wait for hives to be the whole picture, since airway and circulation findings are what confirm anaphylaxis and demand immediate epinephrine.
Before you speak
Define the moment and the information you actually have
An emergency-department presentation immediately on arrival by ambulance, before any treatment has been given.
The emergency team needing an immediate action-oriented update rather than a full history.
History, vital signs, and a focused skin, airway, and respiratory exam. No laboratory studies are part of this simulation.
About 45 seconds
Fictional training case: The presentation is locked to the simulated patient JSON. It names important unknowns instead of inventing an examination, vital signs, allergies, or tests.
Complete spoken example
First, read it once without stopping
The paragraph breaks show the clinical shape. In a real presentation, pause briefly between ideas rather than announcing the headings.
Mr. Green is a 19-year-old man with a known peanut allergy who developed hives, throat tightness, and wheezing within 15 minutes of eating food containing peanuts; this is anaphylaxis and epinephrine is being given now.
He has widespread hives, lip and tongue swelling, throat tightness, wheezing, and lightheadedness, all beginning within 15 minutes of the exposure. He forgot his epinephrine auto-injector at home.
He has a known peanut allergy since childhood and mild asthma, and uses an albuterol inhaler as needed; he is a college student.
His vitals show a heart rate of 134, blood pressure 82 over 46, respiratory rate 28, and oxygen saturation 89% on room air, with inspiratory stridor and diffuse wheezing on exam.
This is severe anaphylactic shock from peanut exposure, with airway compromise and hypotension, and needs immediate and possibly repeated epinephrine rather than further diagnostic discussion right now.
I have given intramuscular epinephrine into the anterolateral thigh and will repeat it every five to ten minutes if he remains hypotensive or refractory. He is positioned lying down with his legs elevated rather than sitting up, and I am giving high-flow oxygen and an IV fluid bolus, with antihistamines and other adjuncts to follow but not to delay epinephrine.
Build the presentation
Give every sentence one job
A presentation is a compressed clinical argument, not a chart read aloud. These six moves keep the facts connected to your reasoning.
Opening one-liner
Name the trigger and the emergency together
“Mr. Green is a 19-year-old man with a known peanut allergy who developed hives, throat tightness, and wheezing within 15 minutes of eating food containing peanuts; this is anaphylaxis and epinephrine is being given now.”
Why it belongs: Stating that epinephrine is already being given in the first sentence tells the team the diagnosis has been made and treatment is underway, which is more urgent than a routine history-first presentation.
He's having an allergic reaction to peanuts.
This is anaphylaxis with airway and skin involvement, and epinephrine is being given now.
Why: Naming the diagnosis and stating treatment is already underway is more actionable than describing an allergic reaction generally.
History of present illness
Give the multi-system findings briefly
“He has widespread hives, lip and tongue swelling, throat tightness, wheezing, and lightheadedness, all beginning within 15 minutes of the exposure. He forgot his epinephrine auto-injector at home.”
Why it belongs: Naming involvement across skin, airway, respiratory, and circulatory systems together is what confirms this as anaphylaxis rather than a milder allergic reaction confined to the skin alone.
He has hives and feels a bit short of breath.
He has hives, throat tightness, wheezing, and lightheadedness together, confirming multi-system involvement.
Why: Naming multiple systems together is the specific criterion that defines anaphylaxis, not skin symptoms alone.
Relevant background
Confirm the known allergy and asthma comorbidity
“He has a known peanut allergy since childhood and mild asthma, and uses an albuterol inhaler as needed; he is a college student.”
Why it belongs: Known asthma is a specific risk factor for more severe or fatal anaphylaxis and is worth stating explicitly, not just as background detail.
He has asthma too.
He has known peanut allergy and mild asthma, which is a specific risk factor for more severe anaphylaxis.
Why: Stating why the asthma history matters is more useful than mentioning it in passing.
Objective data
State vitals confirming the severity
“His vitals show a heart rate of 134, blood pressure 82 over 46, respiratory rate 28, and oxygen saturation 89% on room air, with inspiratory stridor and diffuse wheezing on exam.”
Why it belongs: The hypotension and hypoxemia confirm this is severe anaphylaxis with airway and circulatory compromise, not a mild reaction, and justify repeat dosing of epinephrine if needed.
His blood pressure and oxygen are low.
His blood pressure is 82 over 46 and oxygen saturation is 89%, with stridor and wheezing, confirming severe multi-system involvement.
Why: Exact values convey the true severity more precisely than 'low.'
Assessment
State the diagnosis plainly
“This is severe anaphylactic shock from peanut exposure, with airway compromise and hypotension, and needs immediate and possibly repeated epinephrine rather than further diagnostic discussion right now.”
Why it belongs: In a true anaphylaxis emergency, the assessment should direct the room toward action, confirming severity rather than exploring alternative diagnoses.
This looks like a bad allergic reaction.
This is severe anaphylactic shock with airway compromise and hypotension, needing immediate treatment.
Why: Naming the diagnosis and severity plainly tells the team to act now.
Plan
State epinephrine dosing, positioning, and next steps
“I have given intramuscular epinephrine into the anterolateral thigh and will repeat it every five to ten minutes if he remains hypotensive or refractory. He is positioned lying down with his legs elevated rather than sitting up, and I am giving high-flow oxygen and an IV fluid bolus, with antihistamines and other adjuncts to follow but not to delay epinephrine.”
Why it belongs: Stating the specific muscle site, the repeat-dosing interval, and the positioning correction together addresses the most common and dangerous errors in anaphylaxis management: underdosing epinephrine and standing a hypotensive patient up.
I gave him an EpiPen and some Benadryl.
I gave intramuscular epinephrine into the anterolateral thigh and will repeat it if needed; antihistamines are a secondary adjunct, not a substitute.
Why: Naming epinephrine as the primary treatment and antihistamines as secondary corrects a common and dangerous misunderstanding.
Do not fill the blanks
Say what has not yet been established
Real presentations often happen before the chart is complete. A brief, explicit limitation is safer and more credible than a polished invention.
Response to the first epinephrine dose over time
Say: “A repeat set of vitals after the first epinephrine dose is not yet available in this simulation, and I would reassess him within minutes to guide whether a second dose is needed.”
Anaphylaxis can be biphasic, and ongoing reassessment, not a single snapshot, determines whether further treatment is needed.
Tryptase level
Say: “A serum tryptase level is not part of this simulation and is not needed for acute treatment, though it can be useful later to help confirm the diagnosis.”
Acute management should never wait for a confirmatory lab that does not change the immediate treatment decision.
Clinical compression
What leads, what stays, and what can wait?
| Source detail | Decision | Reason |
|---|---|---|
| Hives, throat tightness, wheezing, and lightheadedness within 15 minutes of peanut exposure | Lead | This multi-system combination and rapid timing define anaphylaxis and its urgency. |
| Forgot his epinephrine auto-injector at home | Compress | Worth a brief mention for context, but should not slow down the emergency presentation. |
| College student, non-smoker | Omit | This detail does not change emergency management. |
| Hypotension of 82 over 46 with oxygen saturation of 89% | Lead | These vitals confirm the severity and justify aggressive, repeated treatment. |
| Known mild asthma | Include | It is a specific risk factor for more severe or fatal anaphylaxis worth naming explicitly. |
After the presentation
Likely attending questions
Answer the question first, then give the evidence. If the source case does not contain the answer, say what you would verify.
Why epinephrine before antihistamines?
Epinephrine is the only medication that reverses the airway swelling and circulatory collapse of anaphylaxis; antihistamines and corticosteroids help with skin symptoms and may reduce biphasic reactions but do not substitute for epinephrine and should never delay it.
Why lay him down with legs elevated instead of letting him sit up?
In anaphylaxis with hypotension, sitting or standing suddenly can cause fatal empty-vena-cava syndrome from reduced venous return; positioning him supine with legs elevated helps preserve blood return to the heart.
How do you decide whether to repeat epinephrine?
If he remains hypotensive, has persistent airway symptoms, or does not improve within five to ten minutes of the first dose, a repeat intramuscular dose is given; ongoing reassessment of vitals guides this rather than a fixed single dose.
Self-check
A 30-second check before you present
- State the trigger and that epinephrine is already being given, in the first sentence.
- Name multi-system involvement, not just skin findings.
- Report vitals to confirm severity, including blood pressure and oxygen saturation.
- Name asthma as a specific risk factor for severe anaphylaxis if present.
- State the epinephrine site, dose interval, and positioning explicitly.
- State that antihistamines are secondary, not a substitute for epinephrine.
- State the plan for reassessment and possible repeat dosing.
- Keep the whole presentation shorter than a routine new-patient presentation.
Common presentation problems
Repair the habits that make a case hard to follow
Leading with 'he has hives' instead of naming anaphylaxis
Repair: State the diagnosis and that epinephrine is being given, in the first sentence.
Describing antihistamines as the main treatment
Repair: State that epinephrine is the primary treatment and antihistamines are a secondary adjunct.
Sitting a hypotensive patient upright
Repair: State that he is positioned supine with legs elevated instead.
Treating one epinephrine dose as sufficient without reassessment
Repair: State the plan to reassess and repeat dosing if he remains hypotensive or refractory.
Frequently asked questions
Oral case presentation questions
How short can this presentation really be?
Shorter than almost any other case: trigger, systems involved, vitals, and that epinephrine has been given is enough in the acute moment; full allergy history and observation planning can follow once he is stabilized.
Do I need to mention discharge planning in the initial presentation?
Not in the acute moment; mention observation duration and auto-injector prescription once he is stabilized, since the immediate priority is treatment, not discharge planning.
Should I mention corticosteroids?
You can mention they are given as an adjunct, but state clearly that they do not reliably prevent biphasic reactions and must never delay epinephrine or other resuscitation.
