Acute renal failure due to mannitol intoxication

Area of Science:

• Nephrology
• Pharmacology

Background:

• Mannitol is an osmotic diuretic commonly used to reduce intracranial pressure and treat cerebral edema.
• While generally safe, mannitol can occasionally cause adverse renal effects, including acute kidney injury.

Observation:

• A case of acute renal failure directly attributed to mannitol administration is presented.
• This case is contextualized with a review of previously documented instances of mannitol-induced renal dysfunction.

Findings:

• The review suggests that hyperosmolarity and direct tubular toxicity are potential mechanisms underlying mannitol-induced renal failure.
• Specific patient factors may predispose individuals to developing this adverse effect.

Implications:

• Clinicians should be aware of the potential for mannitol to cause renal failure, especially in susceptible patients.
• Further research into the precise mechanisms and risk factors is warranted to improve patient safety during mannitol therapy.
