| Scientific title | |
| Study objectives | Recombinant human deoxyribonuclease (rhDNase) can liquefy mucous in children with an atelectasis during mechanical ventilation, resulting in improved mucociliary clearance, less mucous retention and less airway obstruction, thereby enhancing the rate of resolution of an atelectasis. Moreover we expect the ventilator settings, pulmonary ventilation and ventilation-perfusion mismatch to improve faster, possibly resulting in a shorter time spent on a ventilator and on the Intensive Care Unit (ICU). |
| Ethics approval(s) | Ethics approval received from the local medical ethics committee |
| Health condition(s) or problem(s) studied | Atelectasis during mechanical ventilation |
| Intervention | Intervention group: Twice daily: inhaled rhDNase, 2.5 ml and twice daily 4 ml isotonic saline (NaCl 0.9%), for two days. Control group: Twice daily: inhaled isotinic saline 2.5 ml and twice daily 4 ml isotonic saline, for two days. |
| Intervention type | Drug |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Recombinant human deoxyribonuclease (rhDNase) |
| Primary outcome measure(s) |
Change in a Chest radiograph-score (CXR-score) at 48 hours. |
| Key secondary outcome measure(s) |
1. Change in a Chest radiograph-score at 24 hours |
| Completion date | 31/12/2010 |

| Target sample size at registration | 80 |
| Key inclusion criteria | 1. Aged zero to 18 years 2. Mechanical ventilation 3. Presence of an atelectasis on a chest radiograph 4. First dose of study medication can be administered preferably within six hours (maximum 12 hours) after an atelectasis has been diagnosed |

Mechanical ventilation during muscle paralysis 4. Atelectasis due to a bronchoscopically diagnosed: a. foreign body aspiration b. tracheal or bronchial compression by lymph nodes or vessels 5. Recurrent atelectasis due to an anatomical airway-abnormality 6. RhDNase treatment in the previous 48 hours 7. Clinical condition or ventilator settings that are not compatible with nebulising medication (according to the responsible physician) 8. Presence of a pneumothorax 9. Previous participation in the study |
