Thyroid storm / life-threatening thyrotoxicosis

Recognise life-threatening decompensated thyrotoxicosis and initiate senior endocrine and critical-care escalation alongside supportive treatment.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 36-year-old with untreated thyrotoxicosis presents with fever, agitation, diarrhoea, atrial fibrillation and heart failure features.

01 · RECOGNISE

Frame the danger first.

  • Thyroid storm is a clinical diagnosis of decompensated thyrotoxicosis; do not wait for hormone results to escalate.
  • Fever, delirium, marked tachycardia, heart failure and gastrointestinal symptoms can coexist.
  • Look for infection, surgery, medicine non-adherence or other precipitants.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Use ABCDE and involve senior endocrinology and critical care immediately.
  2. Treat physiological complications and seek the current local endocrine emergency regimen.
  3. Investigate and manage the precipitant in parallel with supportive care.
  4. Monitor cardiac rhythm, temperature, fluid balance, liver function and neurological state closely.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Shock, pulmonary oedema, malignant arrhythmia or severe heart failure
  • Hyperthermia, delirium, seizure or reduced consciousness
  • Rapid deterioration despite initial physiological support
04 · COMMON ERRORS

What makes care less safe.

  • Waiting for thyroid-function results before escalating
  • Using remembered treatment sequences rather than the current protocol
  • Ignoring a precipitant such as sepsis or acute coronary syndrome
05 · STRUCTURED HANDOVER

Say the concern plainly.
