    AbstractIn 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. Pulmonary and systemic hemodynamics were determined on the basis of pulmonary artery catheter measurements. Oxygenation ratio (PaO2/FiO2) and pulmonary shunt (Qs/Qt,%) were calculated. Extravascular lung water (EVLW, ml/kg body weight) was determined by double indicator thermodilution technique. Total injury severity by injury severity score (ISS) was 29.6 +/- 6 points (KIN) and 31.6 +/- 5 points (KON). The oxygenation ratio (PaO2/FiO2) increased significantly from 140 +/- 45 (day 0) to 237 +/- 40 (p < 0.05) [day 5] (KIN), in KON patients no improvement (143 +/- 48 [day 0], 133 +/- 44 [ay 5]) was seen (p < 0.05 between groups). There were no significant changes of systemic hemodynamics between the groups or compared to day 0. Pulmonary shunt decreased significantly from 26.6 +/- 4% (day 0) to 12.5 +/- 2% (day 5) (p < 0.05) in KIN patients and was 36.6 +/- 6% at day 0 and 31.4 +/- 2% at day 5 in KON patients (p < 0.05 between groups). EVLW was 11.1 +/- 2 ml/kg body weight at day 0 and 9.4 +/- 1 ml/kg body weight at day 5 (KIN)-EVLW was 12.9 +/- 2 ml/kg body weight at day 0 and 17.4 +/- 3 ml/kg body weight at day 5 (KON) (not significant). 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.
