Comparative StudyModulation of pulmonary vascular resistance and edema formation by short-term infusion of a 10% fish oil emulsion.
The aim of this study was to investigate whether the pulmonary response to inflammatory stimulation, resulting in increased vascular resistance and permeability, could be attenuated by short-term infusion of triglycerides containing omega-3 fatty acids. With the concept of altering the composition of membrane phospholipids in such a manner that stimulation resulted in the release of less vasoconstrictive and permeability-enhancing metabolites of eicosapentaenoic acid instead of those of arachidonic acid (AA), the parenteral application of a lipid emulsion prepared from fish oil (Omegavenös) was tested in comparison with a soy oil preparation (Lipovenös). ⋯ The data demonstrate that omega-3 fatty acids seem to be incorporated into the phospholipid pool of the pulmonary tissue, even after short-term infusion (3 h) resulting in an attenuated pressure reaction and edema formation due to an altered spectrum of metabolites in the case of inflammatory stimulation.

Posttraumatic adult respiratory distress syndrome (ARDS) still involves significant mortality, despite progress in management concepts. Current therapeutic strategies are briefly described, including kinetic therapy, high-frequency jet ventilation and extracorporeal membrane oxygenation. ⋯ This young man with severe posttraumatic ARDS developed a potentially lethal bilateral pulmonary hemorrhage under treatment with ECMO, and on the basis of this bilateral pulmonary transplantation was considered to be indicated. The patient is alive and well 2 years after the procedure.

Randomized Controlled Trial Clinical Trial
[Effect of continuous change in axial position in treatment of post-traumatic lung failure (ARDS). A clinical study].
In the treatment of posttraumatic adult respiratory distress syndrome (ARDS) so far no breakthrough has been achieved. In several cases of severe ARDS we have seen improvements of lung function by means of continuous body positioning. We therefore compared the effect of kinetic positioning (KIN) on lung function and hemodynamics in ARDS patients to conventional (KON) supine positioning. 22 ARDS patients with multiple trauma treated by supportive continuous body positioning (KIN) (KCI-Mediscus) and without continuous positioning (KON) were investigated daily. ⋯ We found no hemodynamic side effects from continuous body positioning. In ARDS-patients submitted to body positioning oxygenation and pulmonary shunt improved significantly and were significantly better compared to those with conventional supine positioning. Continuous body positioning appears to represent a promising supportive treatment regimen in posttraumatic ARDS.

Bronchopleural fistula (BPF) continues to present a treatment problem in mechanically ventilated patients. We report a patient with a traumatic BPF, pneumonia, and adult respiratory distress syndrome (ARDS) who was successfully ventilated with pressure-controlled ventilation (PCV). This mode, by allowing the use of lower inspiratory airway pressures, may promote closure of the fistula.
