ARDS in adults has recently been shown to improve by exogenous surfact
ant therapy. However, regarding surfactant therapy in children with AR
DS only few data exist to date. Therefore, we analyzed retrospectively
18 children with ARDS, who were treated with 69 endotracheal applicat
ions of bovine surfactant. Patients with good clinical response receiv
ed repeated surfactant applications, usually at 8-24 hours intervals.
The causes of ARDS were pneumonia, lung hemorrhage, and toxins liberat
ed during surgery. The interval between first signs of ARDS and surfac
tant application varied from 2.2 to 67.5 days. Within 30 to 120 min af
ter surfactant application the PaO2/FiO2-ratio, the AaDO2, and the oxy
genation index (OI) improved significantly. Responders to therapy had
a 40% higher probability of survival than non-responders (p < 0.0001).
Five of 18 patients (28%) survived. In all studied cases, surfactant
deficiency and grossly impaired lung function could be demonstrated pr
ior to treatment. We conclude that surfactant replacement therapy in c
hildren with ARDS improves gas exchange significantly.
