Severe hyponatremia with seizure
Educational use only. Not clinically reviewed58-year-old woman for Emergency stabilization, hypertonic-saline intent, and correction surveillance. About 9 simulated minutes.
What you will practise
- Recognize severe symptomatic hypotonic hyponatremia from the seizure, depressed alertness, confirmed sodium, glucose, and osmolality.
- Record injury protection, airway and breathing support, monitoring, access, glucose review, and expert escalation in parallel.
- Record immediate local-protocol intermittent hypertonic-saline bolus intent in a closely monitored setting.
- Review the fixed first-hour neurologic state and sodium rise, then stop hypertonic saline after the immediate target is met.
- Set correction ceilings, monitor sodium and urine output, investigate the cause, stop contributors, and retain an overcorrection contingency.
