- Cardiac arrhythmia / arrest (multiple)
- Metabolic acidosis (lactate)
- Very high mortality
- Sedate and paralyse the patient (non-depolarising). The aetiology of the hyperpyrexia is unclear and may be due to serotonin toxicity or malignant hyperpyrexia, it is therefore important to avoid drugs that may trigger/exacerbate these conditions e.g. Fentanyl, suxamethonium chloride.
