Atypical presentation
Goodge Street — when anaphylaxis did not look like the textbook
A young woman at Goodge Street Underground station suddenly reported that she could not see. She had taken her first dose of erythromycin and was intensely itchy and scratching.
The safest response was not to force a diagnosis too early or push her through a packed rush-hour environment. She was supported, observed and accompanied while the picture evolved; when breathlessness appeared, the response changed with it.
What made it difficultThe presentation did not begin with the obvious airway or breathing picture people expect from anaphylaxis.
What was noticedThe important thing was that the clinical picture was changing. Later, shortness of breath developed.
What was doneThe environment was made safer, the person was supported and observed, then taken off the Tube near UCH when the picture evolved. 999 was called and support continued until ambulance clinicians took over.
What happened nextThe evolving presentation was subsequently understood in the context of anaphylaxis.
When the picture changes, change your response.
Reassessment
2 a.m. festival anaphylaxis — treatment did not end the emergency
During a large outdoor festival, a person with a lifelong history of severe anaphylaxis developed a significant reaction with breathlessness, rash and itching, dizziness and stridor.
The first adrenaline dose had not produced a sufficient response. The team still had to think ahead: prepare oxygen and resuscitation equipment, organise escalation, keep reassessing and be ready for the airway and breathing picture to worsen.
What made it difficultShe had already self-administered adrenaline, creating the temptation to regard the emergency as treated.
What was noticedThe response was incomplete and the airway/breathing risk remained significant.
What was doneFurther adrenaline was coordinated, oxygen and airway/resuscitation equipment were prepared, ambulance and hospital escalation was organised, and the situation was repeatedly reassessed.
What happened nextSymptoms only settled after repeated treatment and the person was escorted to A&E.
Treatment does not end the emergency. Reassessment does.
Trajectory
All Things Fungi — when “not obviously deteriorating” was not reassuring
At a small alcohol-free festival, a woman in her mid-50s with significant pre-existing autoimmune disease was profoundly tired and pale, with poor sleep and some breathlessness — but without the dramatic collapse that makes decisions easy.
Her underlying illness, pallor, exhaustion and breathlessness mattered as a pattern rather than as isolated observations. The decision was less about whether she needed an ambulance that second and more about whether a festival remained an appropriate place for her to stay.
What made it difficultNo single observation screamed emergency. The challenge was the overall context, comorbidity and trajectory.
What was noticedA systematic assessment and history left a persistent sense that remaining at the festival was not safe.
What was doneRather than waiting for obvious deterioration, arrangements were made to bring a vehicle to her and get her off site with support.
What happened nextHer friend later reported that she had been admitted to intensive care roughly 24 hours later.
Stable now does not mean safe to stay.
Decision framework
Stable Is Not Safe — knowing when someone should leave
“Stable” describes a moment. It is not necessarily a forecast of the next six hours.
This framework grew out of repeated situations where the snapshot looked tolerable but the environment, monitoring capacity or direction of travel did not. A person can be stable at 8 p.m. and still be unsafe to keep on site overnight.
What makes the decision difficultThe choice is not always “ambulance or no ambulance”. Sometimes the real decision is whether the current environment remains appropriate.
What to noticeDistance from definitive care, night-time, staffing, environmental exposure, underlying disease, ability to monitor and direction of travel.
What to doLower the threshold for leaving an environment when monitoring is weak, transfer is slow or deterioration would make later evacuation harder.
How FieldSafe applies itTeams are taught to ask not only whether somebody needs 999 now, but whether it is actually safe for them to remain.
Stable is a description of now. Safe is a decision about what comes next.
Remote & overseas
Extreme heat, vomiting and the red flag everybody else was missing
During an overseas pilgrimage in very hot conditions, a participant developed significant vomiting and diarrhoea alongside demanding retreat activities. People around them were repeatedly checking temperature.
The setting included extreme heat, repeated fluid loss and physically demanding retreat activity. Hourly temperature checks were easy to focus on, but reduced urine output and the overall trajectory were the clues that waiting in the hotel was no longer enough.
What made it difficultThe obvious symptoms and retreat context provided an easy explanation for the illness.
What was noticedThe more important deterioration marker was that the participant had not passed urine for more than 12 hours and was continuing to worsen.
What was doneEscalation beyond hotel-room observation was strongly recommended and transfer for proper clinical assessment arranged.
What happened nextThe participant subsequently required ongoing treatment, intravenous fluids and monitoring.
Do not let the retreat context explain everything away.
Operational leadership
Preparing for a major incident — protecting thousands before anything happens
As an event environment grew from hundreds of people to several thousand, the role shifted from treating individual casualties to coordinating medical and first-aid provision alongside private ambulance crews and other responders.
As the event grew, preparedness became less about the individual first-aid bag and more about command, communication and contingencies. Radios, access, responder coordination, heat, water supply and simultaneous incidents all became part of the medical picture.
What made it difficultLarge events create risks that may never present as one obvious casualty: heat, water failure, access problems, communication failures and simultaneous incidents.
What was noticedOperational readiness depends on radios, briefings, escalation arrangements, visible leadership and understanding the whole site.
What was doneProvision was coordinated with other responders, with structured communication, briefings/debriefings and contingency planning.
What happened nextThe value of preparedness remained largely invisible — because systems were already in place before they were needed.
Event medicine begins before anybody becomes a casualty.
