Summary
Two patients experienced severe seizures hours after enflurane anesthesia. Laudanosine, a metabolite, and other factors may have contributed to these post-anesthesia convulsions.
Area of Science:
- Anesthesiology
- Neuroscience
- Pharmacology
Background:
- Enflurane is an inhalational anesthetic agent.
- Atracurium is a neuromuscular blocking agent whose metabolite is laudanosine.
- Cephazolin is an antibiotic.
Observation:
- Two patients developed generalized convulsions hours after anesthesia supplemented with enflurane.
- One patient experienced status epilepticus 7 hours post-anesthesia, the other a myoclonic convulsion 17 hours post-recovery.
- Neither patient had a prior history of epilepsy or seizures.
Findings:
- Post-anesthesia convulsions occurred in patients receiving enflurane.
- The metabolite of atracurium, laudanosine, is suspected as a potential contributing factor.
- Synergistic effects with cephazolin and photic stimulation are also considered.
Implications:
- This case report highlights a potential risk of seizures associated with enflurane anesthesia.
- Further investigation into the role of laudanosine and other factors in post-anesthetic seizures is warranted.
- Clinicians should be aware of this potential adverse effect and monitor patients accordingly.
