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.
