Abstract:
A 25-year-old paraplegic woman suffered cardiopulmonary arrest due to a major pulmonary embolism during intravenous mannitol therapy. Although it is possible that the mannitol caused an acute episode of hemagglutination, we postulate that rapid administration of mannitol caused dilation of her venous system, causing a preexisting clot to break loose.
Insights
Rapid mannitol infusion may trigger pulmonary embolism in paraplegic patients. The therapy dilated veins, potentially dislodging a pre-existing clot, leading to cardiopulmonary arrest.
Area of Science:
- Cardiology
- Pharmacology
- Neurology
Background:
- Intravenous mannitol is used for managing intracranial pressure.
- Pulmonary embolism is a serious complication that can lead to cardiopulmonary arrest.
Observation:
- A 25-year-old paraplegic woman experienced cardiopulmonary arrest during intravenous mannitol therapy.
- The event occurred during administration of mannitol, a hyperosmotic agent.
Findings:
- A major pulmonary embolism was identified as the cause of cardiopulmonary arrest.
- The rapid administration of mannitol may have caused venous dilation, leading to the dislodgement of a preexisting clot.
Implications:
- Clinicians should consider the potential risk of pulmonary embolism in patients receiving rapid mannitol infusions, especially those with predisposing factors like paralysis.
- Further research is needed to elucidate the precise mechanism linking mannitol administration to pulmonary embolism.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
