Clinical Pearl

"Guidelines end where real clinical judgment begins. Protocols support decisions, but calm thinking, pattern recognition, and decisive action save lives."

Sources & review log

Last full review: 31 May 2026. Every card links directly to its official source so you can verify against the primary guidance.

Primary guidance used

What changed in this review

Resuscitation, peri-arrest, hypothermia and anaphylaxis cards re-cited to Resuscitation Council UK 2025 and NICE NG258 (2026).
Post-ROSC temperature guidance updated to current fever-prevention targets (≤37.5°C); routine 32–36°C cooling no longer mandated.
Anaphylaxis updated: corticosteroids no longer routine, risk-stratified observation (2/6/12h), tryptase timing and two-auto-injector discharge per NICE NG258.
Four priority algorithms added: Refractory Anaphylaxis, Major Haemorrhage, Local Anaesthetic Systemic Toxicity (LAST) and Opioid Overdose.
Every card now carries direct official-guidance links, learning-resource links, a last-reviewed date and a safety disclaimer.

Known limitations

This is a revision and teaching resource, not a clinical protocol. Local Trust policy and senior advice always take precedence.
Drug doses are typical adult values unless stated; verify against the BNF / BNFc and adjust for weight, age, renal and hepatic function.
TOXBASE requires an NHS login; some external learning resources link to a topic hub rather than a single fixed video.
