Case Reports[Perioperative management of the patient with atypical Parkinson disease].
Recent neuropathological findings define that 10-20% of the Parkinson patients belong to the atypical Parkinson's syndrome due to multi-system disease marked by typical Parkinsonian symptoms such as rigor, tremor and akinesia and early onset of severe autonomic, cerebellar or pyramidal disorders. Symptoms like postural hypotension, dysphagia, hypersalivation, urinary bladder dysfunction, thermodysregulation, abnormalities in eye movement, early falls or dementia etc. are frequently seen in these patients. In these patients dopamin depletion in the nigrostriatal pathway is combined with degeneration of other cerebral structures like olivopontocerebellar and intermediolateral columns. ⋯ Both responded to antiparkinsonian drugs, the first to orally applied L-dopa, the second to intravenous amantadine. Most probably the interruption of the treatment with high dosages of L-dopa (in these patients given in 2-4 hours intervals) had caused these complications. The special nature of the anaesthesiological management of atypical Parkinson patients is reviewed.

Midlatency auditory evoked potentials during anaesthesia with increasing endexpiratory concentrations of desflurane.
Under general anaesthesia with the volatile anaesthetics halothane, enflurane and isoflurane, midlatency auditory evoked potentials (MLAEP) are suppressed dose-dependently. Therefore, MLAEP have been used to measure depth of anaesthesia and to indicate intraoperative awareness. Desflurane is a new volatile anaesthetic and its effect on MLAEP have not been studied previously. ⋯ Based on these observations, endexpiratory concentrations of > or = 4.5 vol % desflurane should suppress awareness phenomena such as auditory perceptions during anaesthesia.

[Does the difference in anesthetic methods influence postoperative nitrogen balance?].
To evaluate the influence of anesthesia on postoperative nitrogen balance after upper abdominal surgery, twenty-seven patients undergoing the surgery were investigated. They were allocated randomly to three groups receiving different anesthetic methods, i.e., epidural anesthesia, general anesthesia or balanced anesthesia. In the epidural anesthesia group, anesthesia was maintained with 0.5% isoflurane, nitrous oxide and oxygen supplemented with epidural analgesia extending from Th 1 to L 3. ⋯ Postoperative values of IL-6 and CRP also did not differ significantly among the three groups. Postoperative WBC was significantly higher in the balanced anesthesia group than in other two groups. The results suggest that the difference in anesthetic methods does not influence postoperative nitrogen balance.
