Convulsion following intrathecal cephaloridine
Insights
Intrathecal cephaloridine administration in an infant caused seizures, confirming its neurotoxicity. Direct administration into the cerebrospinal fluid space is not recommended due to potential central nervous system damage.
Area of Science:
- Neonatal Neurology
- Pharmacology
- Infectious Diseases
Background:
- Meningitis is a serious infection in infants.
- Intrathecal drug administration is used for CNS infections.
- Cephaloridine is an antibiotic sometimes used in treating infections.
Observation:
- An 11-day-old premature infant received intrathecal cephaloridine for suspected meningitis.
- The infant experienced a generalized tonic convulsion post-administration.
- The same convulsive symptoms recurred upon a second intrathecal cephaloridine dose.
Findings:
- Intrathecal cephaloridine administration directly into the cerebrospinal fluid space can induce central nervous system (CNS) toxicity.
- The observed generalized tonic convulsion was a direct adverse effect of cephaloridine.
- The infant's symptoms resolved over six hours, indicating a transient neurotoxic effect.
Implications:
- Cephaloridine should not be administered intrathecally due to its neurotoxic potential.
- Alternative antibiotics or administration routes should be considered for CNS infections in neonates.
- Further research into the neurotoxic mechanisms of cephaloridine is warranted.
Abstract:
Following therapeutic intrathecal administration of cephaloridine to an 11-day-old premature infant with suspected meningitis, a generalized tonic convulsion was observed. Symptoms continued to subside over the next six hours, followed by postictal sleep. That convulsion and other symptoms were due to cephaloridine was confirmed when the second intrathecal administration produced the same symptom. Because of its possible damaging effect on CNS, it is strongly suggested that cephaloridine should not be administered directly into the cerebrospinal fluid space.
