Trial Outcomes & Findings for Dornase Alpha Versus Hypertonic Saline for Lung Atelectasis in Non-Cystic Fibrosis Patients (NCT NCT00671723)

Results Overview

Each CXR was assigned an atelectasis score.(\*) The absence or presence of contralateral hyperinflation was marked as 0 or 1 point, respectively. The absence or presence of mediastinal shift was scored as 0 or 1, respectively. Atelectasis was scored for each lobe. A partial atelectasis of one lobe was scored as one point, whereas complete atelectasis of a lobe was marked as two points. The distinction between infiltrate and atelectasis as well as the total scoring was done by the interpreting radiologist. These results were summed for each CXR. The score range from 0 to 10 with 0 indicates "no atelectasis",higher value indicates progressively more atelectasis. \*Hendriks T, de Hoog M, Lequin MH, Devos AS, and Merkus PJ: DNase and atelectasis in non-cystic fibrosis pediatric patients.
