Delirium is mental dysfunctions occurring as impaired attentional and memory systems with disturbances of consciousness, affectivity, psychomotor activity and sleep patterns. Numerous factors and underlying diseases may be responsible for these non-specific symptoms. Therefore, a thorough evaluation of preadmission history and current clinical status, supplemented by laboratory and extended technical diagnostic procedures, are always required. ⋯ Personal care should be intensified and include help from family members. Most problems arise from agitated, non-cooperative patients. Treatment with clonidine, gamma-hydroxybutyric acid or neuroleptic drugs like perazin and haloperidol may be required to reduce agitation and the activation of sympathetic influence.

Elements of the "open lung concept" are being increasingly included in clinical ventilatory strategies. Despite encouraging experimental investigations to date, relatively few studies exist that examine the clinical application of the complete concept. The aim of this study was to prove that with effective recruitment maneuvers and titrated PEEP levels this concept is applicable in clinical settings. ⋯ Due to elevated liver enzymes within the first 48 hours, titrated PEEP had to be decreased in three patients. The clinical application of the "open lung concept" demonstrated a quick and effective improvement in oxygenation in many patients. Side-effects in some patients limited the use of high PEEP levels.
