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.

In alcohol-dependent in-patients, an adequate drug prophylaxis should be made in order to lower the degree of a developing alcohol withdrawal syndrome (AWS) or to prevent a life-threatening delirium tremens. Pre-condition of successful therapy is a precise diagnosis. In patients, the beginning of whose abstinence is known, carefully-targeted pharmacological interventions can prevent severe imbalances of neurotransmitters. ⋯ In severe cases that require deep sedation or hypnosis, propofol or gamma-hydroxy-butyric acid should be used. Perioperative infusion of alcohol as a prophylactic agent against delirium tremens is regarded as an obsolete therapeutic measure for ethical reasons and because equally good or better results can be achieved by carefully-targeted drug therapy. Due to its easy use, however, the application of alcohol has not yet completely disappeared from the therapeutic spectrum.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative studies of patient positioning for lumbar intervertebral disk operation].
For surgery on lumbar disks by the posterior route, patients are placed either on a Wilson frame or in genupectoral position. The aim of the prospective study was to record and describe the haemodynamic changes resulting from the patients' position. After written informed consent had been received, 80 neurosurgical patients undergoing lumbar disk surgery were randomly divided into two groups; group I--Wilson frame, group II--genupectoral position. ⋯ We recommend the Wilson frame for neurosurgical lumbar disk surgery in cases of cardiovascular or cerebrovascular disorders. The adaptive capacities in the genupectoral position as a result of the modifying distribution of blood volume are limited in these patients. Furthermore, the dose-dependent effects of different anaesthetics on haemodynamic parameters in these prone positions should be explored.

Review[Can lung protective ventilation methods modify outcome?--A critical review].
A large body of experimental and clinical work leaves no room for doubt that mechanical ventilation can contribute to the progression of a lung disease or, in the worst case, produce acute pulmonary damage. The pathophysiological processes involved have been described as barotrauma, volutrauma, atelectrauma and biotrauma. In response, a socalled lung-protective ventilation strategy has been proposed, especially for patients with acute respiratory distress syndrome (ARDS). ⋯ Of these, only prone positioning has become part of routine clinical management, while ECMO is applied in selected cases only. Unfortunately, thus far, none of these measures has passed the litmus test of a randomized controlled trial. Recent large prospective observational studies, however, suggest that only an optimized concert of therapeutic interventions, but not a single measure alone, may improve the outcome of ARDS patients.

Case Reports[Accidental hypothermia--a challenge for rescue service and intensive care].
Accidental hypothermia is a rare clinical picture with different causes. Specific features are shown by patients who have accidents in water, due to rapid cooling. The SARRRAH project (Search and Rescue, Resuscitation and Rewarming in Accidental Hypothermia) was launched to secure fast and professional medical care right up to rewarming by extracorporal circulation. ⋯ Five of the non-survivors belonged to the group of eight patients who were rewarmed by extracorporal circulation. With one exception, they also had the lowest core temperatures. Only a homogeneous and up-to-date documentation will allow further conclusions to be made for improving the concept of therapy.
