ST3 plastics emergencies: how examiners think

The ST3 plastics clinical station keeps returning to the same handful of emergencies, and that is not laziness — it is because they all test the same registrar-level instinct: recognising a clinical diagnosis, refusing to let anything delay definitive surgery, and running resuscitation and theatre preparation in parallel.

The pattern examiners are marking

Take necrotising fasciitis: the entire station turns on whether you treat it as a clinical diagnosis — resuscitating with one hand while booking theatre with the other — or whether you wait for a score or a scan to give you permission. Compartment syndrome is the same test in a different limb; so is the compromised free flap at 2 a.m. In each case the trap is sequential thinking, and the mark is parallel thinking said out loud: “while the Sepsis Six is running, I’m speaking to the consultant on call, the anaesthetist, and CEPOD.”

The registrar test: describe the operation

What separates ST3 answers from CST answers is the operating theatre. The examiner will ask you to walk through the surgery — and a candidate who can say “radical debridement back to bleeding, viable tissue, samples for microbiology and histology, washout, and a planned second look within forty-eight hours” sounds like someone who has held the retractor. Rehearse the operative sequence for each emergency the way you rehearse the resuscitation; it is marked with the same weight.

The twist is part of the format

Expect the scenario to move under you: the patient deteriorates on ITU hours after surgery, the wound edges turn dusky, the noradrenaline climbs. The examiner is testing whether your structure survives new information. It should — re-enter at assessment, and remember that in these diseases the answer to deterioration is almost always a return to theatre, not watchful waiting.

How to practise

Rehearse the core emergencies out loud, on the clock, including the operative steps and a deliberate twist. Reading stops being useful the day you can recite the plan; speaking it under pressure is the skill the panel scores. You can rehearse these exact stations with an AI examiner on Reviva — including the hand-trauma set — with feedback on the official 0–5 scale.

Frequently asked questions

Which emergencies come up in the ST3 plastics interview?

The recurring set: necrotising fasciitis, major burns, compartment syndrome, free flap compromise, and the septic hand. They share one pattern — clinical diagnoses where resuscitation and definitive surgery run in parallel.

How much operative detail does an ST3 answer need?

More than a core-trainee answer. At registrar-entry level the examiner expects you to describe the operation you are proposing — the debridement, the fasciotomy, the take-back — like someone who will be doing it under supervision.

Note. General preparation advice for educational use — always work to current guidelines and local protocols, and confirm the interview format on the official national recruitment portal.
