Abstract
Objectives: The objective of this study is to determine the time to ventilator liberation and decannulation after tracheostomy placement in children with bronchopulmonary dysplasia (BPD) and pulmonary hypertension.
Methods: A prospective cohort study included all children (<18 years old) who underwent tracheostomy between 2015 and 2021 with or without a diagnosis of BPD. The primary outcomes were time to ventilator liberation, tracheostomy decannulation, or death with tracheostomy in place.
Results: A total of 303 children met inclusion with a median (interquartile range [IQR]) age at tracheostomy of 6.9 (IQR: 4.0-49.5) months. A diagnosis of BPD was made for 42% (N = 127) and this group was younger (5.1 vs. 24.5 months, p < .001) and more often had pulmonary hypertension (68% vs. 24%, p < .001). Children with BPD spent a median of 2.9 years (IQR: 1.6-4.0) on ventilation compared to 1.9 years (IQR: 0.9-3.7) for children without BPD (p = .009). The time to decannulation was greater among children with BPD (3.4 vs. 1.8 years, p < .001). However, unadjusted estimates of ventilator liberation (hazard ratio [HR]: 1.05, 95% confidence interval [95% CI]: 0.77-1.44) and decannulation (HR: 1.11, 95% CI: 0.74-1.66) over time were not prolonged by BPD. Pulmonary hypertension was associated with shorter time to death (adjusted HR [aHR] = 1.99, 95% CI: 1.17-3.38, p = .01), while BPD was associated with longer time to death (aHR: 0.38, 95% CI: 0.22-0.67, p = .001).
Conclusion: BPD is associated with increased ventilation and duration of tracheostomy but over time many children with BPD will wean off the ventilator and be decannulated. Pulmonary hypertension and not BPD is associated with increased time to death after tracheostomy.
