Clinical survey and predictors for the development of tracheobronchomalacia in preterm infants

Area of Science:

• Neonatology
• Pediatric Pulmonology
• Respiratory Medicine

Background:

• Tracheobronchomalacia (TBM) is a significant contributor to morbidity and mortality in preterm infants.
• Effective prevention strategies are crucial for improving outcomes in this vulnerable population.
• Identifying specific risk factors for TBM development is essential for targeted interventions.

Purpose of the Study:

• To identify clinical risk factors associated with the development of tracheobronchomalacia in preterm infants.
• To determine optimal cut-off values for identified risk factors to predict TBM.
• To inform early diagnosis and management strategies for TBM in neonates.

Main Methods:

• A retrospective study included 80 preterm infants (≤36 weeks gestation) who underwent flexible bronchoscopy.
• Multivariate logistic regression analysis compared demographic and clinical factors between infants with and without TBM.
• Receiver operating characteristic (ROC) curve analysis determined optimal cut-off values for risk factors.

Main Results:

• Higher peak inspiratory pressure (PIP) and longer duration of intubation were significantly associated with TBM.
• Preterm infants with TBM received higher PIP (OR, 1.067; p=0.020) and were intubated longer (OR, 1.019; p=0.016).
• PIP > 19.5 cmH2O or intubation > 79.5 days indicated a significantly higher risk of TBM.

Conclusions:

• Elevated PIP and prolonged intubation are major risk factors for TBM in preterm infants.
• Infants requiring PIP > 19.5 cmH2O or intubation > 79.5 days warrant bronchoscopy for early TBM diagnosis.
• Early identification and management of TBM can potentially reduce associated morbidity and mortality.
