Propofol Use for Toxin-Related Seizures

Area of Science:

• Toxicology
• Emergency Medicine
• Pharmacology

Background:

• The efficacy of propofol for managing seizures caused by toxins remains uncertain.
• Poison control systems are valuable resources for studying rare adverse events and treatment outcomes.

Purpose of the Study:

• To characterize the utilization and outcomes of propofol in patients experiencing toxin-induced seizures.
• To analyze data reported to a statewide poison system regarding propofol use for poisoning cases.

Main Methods:

• A retrospective review of electronic records from a poison control system (2009-2012).
• Inclusion criteria: adult patients (≥18 years) with seizure codes and mention of propofol.
• Data extracted: demographics, toxins involved, seizure recurrence, and mortality.

Main Results:

• 235 poisoning cases involving propofol as adjunctive therapy were identified.
• Seizures recurred in 15.7% of cases post-propofol administration.
• The mortality rate was 6.8% in cases with known outcomes.

Conclusions:

• Propofol is utilized as an anticonvulsant in poisoned patients, demonstrating adjunctive utility in terminating toxin-related seizures after airway control.
• The optimal timing for initiating propofol therapy in toxin-induced seizures requires further investigation.
• Prospective controlled studies are necessary to define propofol's definitive role in managing these seizures.
