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.

Randomized Controlled Trial Clinical Trial
[Evaluation of postoperative hypoxemia with a pulse oximeter].
We investigated postoperative hypoxemia by monitoring of SPO2 with a pulse oximeter for the first 5 hours in the ward. Forty-eight adults were divided into the general anesthesia along (G) group and the combination of epidural and general anesthesia (E) group. The patients were randomly administered either 3 l. min(-1) oxygen with face mask for the initial 3 hours or room air. ⋯ Significant correlations were found between Spo2 levels and both age (R = 0.75) and preanesthetic Spo2 (R = 0.66) in G group. Spo2 was significantly lower in the patients whose anesthesia was stopped after 5 p.m. than in those who were weaned before 5 p.m. In conclusion, there is a high incidence of postoperative hypoxemia for several hours in the ward, which can be relieved by 3 l. min(-1) oxygen inhalation with face mask.
