Effect of Speaking Valves on Tracheostomy Decannulation.

Area of Science:

• Pediatric Pulmonology
• Respiratory Medicine
• Critical Care

Background:

• Pediatric tracheostomy decannulation protocols show significant practice variability.
• The impact of tracheostomy capping on decannulation is known, but the role of speaking valves (SVs) remains unclear.

Purpose of the Study:

• To investigate the hypothesis that speaking valves (SVs) decrease time to tracheostomy decannulation in pediatric patients.
• To evaluate the effect of SVs on decannulation in a specific cohort of patients with chronic lung disease of prematurity (CLD).

Main Methods:

• Retrospective chart review of 105 pediatric patients with tracheostomies and CLD at a tertiary care children's hospital.
• Data collected included demographics, gestational age, comorbidities, airway surgeries, speaking valve (SV) trials, and tracheitis episodes.
• Statistical analysis utilized logistic and linear regression to assess factors influencing time to decannulation (TTD).

Main Results:

• Of 75 included patients, 70.7% underwent decannulation with a mean TTD of 37 months.
• Patients using speaking valves (SVs) had a significantly longer TTD (52 months) compared to those without SVs (35 months; p=0.008).
• Increased hospital presentations for tracheitis were associated with a 2-month increase in TTD (p=0.011).

Conclusions:

• This study is the first to assess the effect of speaking valves (SVs) on tracheostomy decannulation in pediatric patients with CLD.
• The findings indicate that SV use is associated with a longer time to decannulation in this patient population, contradicting the initial hypothesis.
• Further research is warranted to understand the complex relationship between SVs, tracheostomy management, and decannulation outcomes in children with CLD.
