[A clinical score system for children with ARDS].

In a retrospective study we developed a simple acute respiratory distress syndrome (ARDS) scoring system in order to analyze the severity of ARDS as precisely as possible. From March 1983 to May 1990, 17 children with ARDS were admitted and treated at the pediatric intensive care unit of the University Hospital of Graz. The ARDS score was evaluated as a predictor of outcome. The score is based on four variables: mean airway pressure, oxygenation index, additional number of organ system failure and a radiological score, each of which was assigned a score between 0 and 3 (Table 3). The score was recorded on admission or immediately after respiratory failure and after 24, 48 and 72 h. The patients were divided into survivors and non-survivors. After 24 h of mechanical ventilation the ARDS score was 7.16 +/- 0.79 in survivors and 10.4 +/- 0.4 points in non-survivors (P less than 0.0006). Similar differences were found after 48 and 72 h of therapy. In addition, the predictive power of the ARDS score after 24 h was tested at a level of 8 points. The sensitivity and the positive predictive value were 90%, while specificity and negative predictive value were 85.7%. The correct prediction was 88.2%. We conclude that this simple ARDS score can be an useful prognostic factor in patients with ARDS.
