Summary
Large doses of magnesium trisilicate mixture, an antacid, can cause severe hyperosmolality, dehydration, and coma. Prompt treatment with hypotonic fluids led to full patient recovery.
Area of Science:
- Critical Care Medicine
- Pharmacology
- Nephrology
Background:
- Magnesium trisilicate mixture is a common antacid used for stress ulcer prophylaxis in Intensive Care Units.
- Its efficacy in preventing and treating stress ulcers is well-established.
Observation:
- A patient receiving large doses of magnesium trisilicate mixture developed severe hyperosmolality.
- This led to critical complications including cerebral dehydration and coma.
Findings:
- The case highlights a rare but serious adverse effect of high-dose magnesium trisilicate mixture.
- Hyperosmolality and subsequent neurological impairment were directly linked to the antacid's administration.
Implications:
- Clinicians should be aware of the potential for hyperosmolality with prolonged, high-dose magnesium trisilicate mixture use.
- Hypotonic fluid resuscitation is an effective management strategy for this condition.
- This underscores the importance of vigilant monitoring of electrolyte and osmolality levels in critically ill patients receiving antacids.
