Effect of external high-frequency oscillation on severe cardiogenic pulmonary edema.
Effective gas exchange can be maintained in animals without endotracheal intubation using external high-frequency oscillation (EHFO). The aim of this study was to evaluate the effect of EHFO in patients with respiratory failure due to severe cardiogenic pulmonary edema. Seven patients were ventilated with EHFO for 2h at 60 oscillations·min(-1), with a cuiras pressure of 36 cmH2O (-26 to +10) and an inspiratory to expiratory ratio of 1:1, with EHFO. ⋯ Arterial CO2 pressure (Paco2) did not, however, decrease. Increased stroke volume without a change in pulmonary artery wedge pressure (preload) suggests either improved inotropic function of the left ventricle or reduced left ventricular afterload with EHFO. The use of EHFO may be effective not only for gas exchange but also for left ventricular function in patients with severe cardiogenic pulmonary edema.

Studies using a multimodal approach in order to prognose therapeutic success in patients suffering from back pain were seen to have highly diverse results. However, in spite of various independent health care systems, a common interest prevails in identifying determinants of therapeutic success in order to improve therapy. ⋯ Predicting successful treatment is hardly possible without analyzing individual circumstances, focusing on sociodemographic variables, workplace-related conditions, and aspects of individual motivation. With regard to objective therapeutic success, subjective perceptions proved highly influential. Treatment proved successful only when the patient's perception of functional disability was minimized. Hence, individual perceptions and experiences were more important than physical capabilities.

Randomized Controlled Trial Clinical Trial
Multidisciplinary rehabilitation for chronic back pain in an outpatient setting: a controlled randomized trial.
Based on existing models for pain chronicity and effective treatment strategies for patients with chronic low back pain, a multidisciplinary rehabilitation programme for an outpatient group setting was developed. The main treatment components address the patient's physical functional capacity (functional restoring), cognitive and affective processes (pain management strategies), and behavioural and ergonomical aspects (back school elements). Short-term (immediately after intervention) and long-term effects (at 6-months follow-up) of the intervention were assessed in a randomized controlled study. ⋯ In contrast to post-treatment results, there were also significant improvements in strength and endurance. Overall results testify to the effectiveness of the intervention programme. Future studies (with larger sample sizes) should aim at a further improvement of functional capacity and disability perception, an analysis of differential treatment effects, and strategies for an improved long-term maintenance of the changes induced by the programme.

In the intensive care unit (ICU) setting, the combination of mechanical ventilation and renal replacement therapy (RRT) has been associated with prolonged length of hospital stay, high cost of care and poor outcome. We gathered outcome data on patients who had severe renal dysfunction on transfer to our regional weaning center (RWC) for attempted weaning from prolonged mechanical ventilation (PMV). We screened the admission laboratory values of 1077 patients transferred to our RWC over an 8-year period. We reviewed the medical records of patients with serum creatinine > 2.5 mg/dl. ⋯ Patients who require PMV and RRT have a very poor prognosis. The small number of patients with renal insufficiency not requiring RRT had a more favorable hospital outcome and mortality, but long-term survival remained poor.
