Fatal myeloencephalopathy due to intrathecal vincristine administration
1Department of Paediatrics, College of Medicine, King Saud University, Riyadh, Saudi Arabia.
Abstract:
Vincristine was accidentally given intrathecally to a child with leukaemia, producing sensory and motor dysfunction followed by encephalopathy and death. Separate times for administering vincristine and intrathecal therapy is recommended.
Insights
Accidental intrathecal vincristine administration in a child with leukemia caused severe neurological damage and death. Separating vincristine and intrathecal therapy administration is crucial to prevent fatal outcomes.
Area of Science:
- Pediatric Oncology
- Neuro-oncology
- Clinical Toxicology
Background:
- Leukemia treatment often involves chemotherapy agents like vincristine.
- Intrathecal chemotherapy is used for central nervous system leukemia.
- Vincristine is a vinca alkaloid chemotherapy drug.
Observation:
- A child diagnosed with leukemia received accidental intrathecal administration of vincristine.
- The patient subsequently developed profound sensory and motor dysfunction.
- Encephalopathy and death followed the neurological complications.
Findings:
- Intrathecal vincristine administration is highly neurotoxic.
- The route of administration is critical for vincristine safety and efficacy.
- Accidental intrathecal administration can lead to severe neurological sequelae and mortality.
Implications:
- Strict protocols are needed to prevent medication errors in pediatric oncology.
- Clear separation of administration times for systemic vincristine and intrathecal therapies is essential.
- This case highlights the critical importance of double-checking drug orders and administration routes in high-risk patient populations.
