This included files from the years 2009 till 2013. Aspiration was evidenced by Evans blue dye passing through the vocal chords (VC) and detected by an endoscope passed through the tracheostoma and directed toward the VC. The statistical analysis was done using the U-test considering the duration of LTMV, age, gender, comorbidities, and other factors. Kaplan Meier curves, Log rank test and Cox regression analysis were used to analyse survival.RESULTS: 48/121 patients (40%) aspirated during the swallowing test (ST). 40/48 patients (83%) died within 4 years. Of the patients without aspiration during the ST 39/73 died (53%), p<0.001, hazard ratio 2,8 (95% confidence interval 1,8-4,5). Patients with a positive ST had a 83 % risk for subsequent aspiration, whereas pts with a negative ST had a 15 % risk for subsequent aspiration .CONCLUSION: This case series shows 40 % risk of aspiration in patients with LTMV. These pts have significant higher mortality after 4 years, and evidence for subsequent aspiration can be found in 83 %. ER -
