Tracheostomy in the pediatric trisomy 21 population

Area of Science:

• Pediatric surgery
• Genetics
• Pulmonology

Background:

• Tracheostomy is vital for pediatric airway obstruction (AO) and respiratory failure.
• Trisomy 21 (Down syndrome) patients frequently have conditions requiring tracheostomy.
• Incidence and outcomes of tracheostomy in pediatric trisomy 21 have not been well-documented.

Purpose of the Study:

• To determine the incidence of tracheostomy in pediatric trisomy 21 patients.
• To analyze indications for tracheostomy in this population.
• To assess decannulation rates and mortality associated with tracheostomy in trisomy 21.

Main Methods:

• Retrospective cohort study.
• Analysis of pediatric trisomy 21 patients undergoing tracheostomy between 2004 and 2013.
• Comparison of outcomes based on indication for tracheostomy.

Main Results:

• Tracheostomy incidence in trisomy 21 patients was 1.7% (20/1173) over 10 years.
• Primary indications: airway obstruction (55%), cardiac/pulmonary respiratory failure (CRF) (25%), or both (20%).
• Overall mortality was 30%, significantly higher in CRF (40%) or combined (60%) indications compared to AO (9%). 45% were decannulated.

Conclusions:

• Pediatric trisomy 21 patients exhibit a tracheostomy rate approximately three times higher than the general pediatric population.
• Isolated airway obstruction was the main indication in this cohort, unlike prematurity-related CRF in the general population.
• Mortality and decannulation rates were comparable to the general pediatric tracheostomy population, but outcomes worsened significantly for trisomy 21 patients with CRF.
