    Abstract:
    The mortality rate for the advanced adult respiratory distress syndrome is still high. Nevertheless there are recent publications showing decreasing incidence and an improving survival rate. This is due to early diagnosis as well as differentiated treatment concepts. The use of special therapy methods including extracorporal gas exchange is only possible at specialized centres. This raises the question as to the right timing of the transfer of those ARDS-patients, whose lungs cannot be cured by the therapy standards practiced locally. In a prospective study, all requests for transfer were noted over a period of 36 months (1992 to 1994) and analyzed by a hospital with a special ward for ARDS. In a total of 469 patients the most prominent predisposing diseases were community-acquired pneumonia (26.3%), followed by multiple trauma (24.4%), the postoperative conditions of systemic inflammatory response syndrome (SIRS) or sepsis (21.3%), bronchopulmonary aspiration (5.8%), and status asthmaticus (2.6%). With a mean preventilation time of 9.5 +/- 9 days and a mean ventilatory peak pressure of 39 +/- 8 cm H2O there was a mean oxygenation index (Horrowitz Index) of 95 (+/- 40) mm Hg. The mean Smith and Gordon Ventilator Score was 82.3 (+/- 12.8) and the mean PIF rate (Benzer Score) 12 (+/- 8.6), 121 out of 469 patients were transferred for further specialized therapy. 75 patients were treated on a conventional basis and 46 patients had to be treated with extracorporal lung assistance (ELA) because conventional treatment failed. The mortality rate was 22.3% altogether, in the group with the conventional treatment 16.0% and 32.6% in the group with ELA. As there are no generally accepted guidelines for the transfer of patients with ARDS to specialized centres, an indication for such a transfer must be established taking into consideration the individual patient history. Very early contact with the specialized centre of choice is recommended.
