Neonatal theophylline neurotoxicity
Clinical Pediatrics
|March 1, 1985
Summary
Theophylline overdose in premature infants can cause neurotoxicity, even with frequent administration. This case highlights accidental overdose and prolonged drug elimination half-life leading to infant intoxication.
Area of Science:
- Neonatal pharmacology
- Pediatric neurology
- Clinical toxicology
Background:
- Theophylline is commonly used for respiratory issues in premature infants.
- Neurotoxicity is a rare but serious adverse effect of theophylline.
- This study examines a case of theophylline intoxication in a premature infant.
Observation:
- A 5-month-old premature infant with bronchopulmonary dysplasia and hepatitis developed focal seizures and irritability.
- The infant exhibited systemic signs consistent with theophylline intoxication.
- An unrecognized accidental overdose was identified as the cause.
Findings:
- Theophylline intoxication occurred due to an accidental overdose.
- A prolonged elimination half-life contributed to the clinical toxicity.
- The infant's condition underscores the importance of careful theophylline dosing and monitoring.
Implications:
- This case emphasizes the potential for theophylline neurotoxicity in premature infants.
- It highlights the need for vigilant monitoring of drug levels and potential overdose.
- Understanding theophylline's toxicity mechanisms is crucial for safe neonatal care.
