Critical-care, cardiology and emergency clinicians get a bedside approach to broad-complex tachycardia, VT storm and torsades. The useful distinctions are structural heart disease versus acquired long-QT triggers, with synchronised cardioversion, sedation, vasopressors, sympatholysis and device interrogation in view.

Allergy labels need phenotype, timing and severity before they reshape critical care choices. Alpha-gal syndrome, latex-fruit reactions, protamine hypersensitivity and iodine myths are used to separate true clinical risk from inherited labels that block useful treatment.

ICU sustainability is framed as high-value care, not rationing. Deprescribing, enteral conversion, correct waste segregation, fewer unnecessary investigations and safe reuse of patient-specific items can reduce carbon impact while removing low-value treatment.

APRV is a specialist listen for clinicians who manage severe ARDS. The point is not a new ventilator recipe: T low, waveform review, carbon dioxide trends and spontaneous effort all decide whether recruitment is helping or causing harm.

For clinicians around transplant or ECMO services, this gives the practical ICU questions that shape candidacy and graft survival. The distinctions around status seven, awake tracheostomy or ECMO bridging, primary graft dysfunction, and infection versus rejection are the main reasons to spend the time.

The action is to diagnose DKA with ketonaemia, acidaemia, bicarbonate and the anion gap, then keep looking for the trigger. Open this for a practical refresher on euglycaemic DKA, potassium-first thinking, balanced crystalloids, and why insulin continues after glucose starts to fall.

Toxicology decisions often depend on bedside pattern recognition before levels return. Clonus, pupil findings, ECG changes, andacid-base status narrow the toxidrome, while naloxone should be titrated to ventilation, not full wakefulness, and toxic alcohol poisoning merits early fomepizole on clinical suspicion.
