This study found no evidence that nebulized recombinant human deoxyribonuclease (rhDNase) improves cough in children with airway malacia and respiratory infections. Placebo was even better for nighttime cough relief.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Clinical Trials
Background:
- Tracheomalacia, a tracheal deformity, presents with diverse respiratory symptoms in children.
- Current treatments include medical management, ventilation (CPAP, BiPAP), and surgical interventions like stenting.
Discussion:
- A single randomized controlled trial (RCT) evaluated nebulized rhDNase versus placebo in children with airway malacia and respiratory infection.
- The study found no significant difference in cough-free proportions but favored placebo for nighttime cough reduction.
Key Insights:
- Limited evidence supports current therapies for intrinsic tracheomalacia.
- Nebulized rhDNase did not demonstrate efficacy and may potentially worsen recovery in children with airway malacia and infection.
Outlook:
- Further RCTs are needed for less severe tracheomalacia, focusing on antibiotics and chest physiotherapy.
- Future research should incorporate tracheal measurements and physiological outcomes alongside clinical assessments.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
