Cervical spinal cord, root, and bony spine injuries: a closed claims analysis.

abstract：:Some previous reports indicate that the excitability of the brain may be increased for days following enflurane anesthesia. The authors investigated this possibility in cats by determining whether or not pentylenetetrazol- (Metrazol) or lidocaine-seizure thresholds decreased after repeated enflurane exposure. The lido...
