Obese Tracheostomy: A Challenging Path From Surgery to Decannulation

Area of Science:

• Otolaryngology
• Pulmonology
• Bariatric Medicine

Background:

• Tracheostomy decannulation guidelines are lacking, especially for obese patients.
• Limited long-term outcome data exists for obese individuals post-tracheostomy.

Purpose of the Study:

• To evaluate tracheostomy outcomes in obese patients from surgery to decannulation.
• To assess rates of tracheostomy downsizing and decannulation success.
• To identify pre-, intra-, and postoperative factors influencing tracheostomy downsizing and decannulation.

Main Methods:

• Retrospective cohort study of 82 obese patients (BMI >30 kg/m²).
• Analysis of pre-, intra-, and postoperative variables for predictive value.
• Statistical analysis including chi-squared test, ANOVA, t-test, and regression models.

Main Results:

• 75.6% of subjects were successfully downsized, and 47.6% were decannulated.
• Increased BMI correlated with longer decannulation times and reduced success rates.
• For BMI ≥30 kg/m², downsize success was 93.5% and decannulation success was 89.7%.

Conclusions:

• Obese patients have increased risks of complications and tracheostomy dependence.
• Patient's body mass index (BMI) is a critical factor in planning decannulation progression.
