SCRIGNA, Mariana et al. Decanulación después de la estadía en UCI: Análisis de 181 pacientes traqueotomizados. Rev. amer. med. respiratoria [online]. 2013, vol.13, n.2, pp.58-63. ISSN 1852-236X.

Objective: Find predictors of decannulation in tracheostomized patients and without mechanical ventilation. A secondary objective was the analysis of mortality in the weaning center and survival at discharge. Material and methods: We reviewed, retrospectively, the medical records of patients admitted to the weaning center with tracheostomy and without mechanical ventilation between January 2004 and June 2011. Different variables as possible predictors of decannulation were studied. Mortality at weaning center and outcomes during follow up after discharge were analyzed. Results: We included 181 patients with an average age of 62 years old. Decannulation was carried out in 44.2% of the patients. The decannulation process took 20 days. The univariate analysis found six variables associated with decannulation failure: male gender, respiratory or cardiovascular history, albumin at admission to the weaning center, days of hospitalization in the weaning center and admission to intensive care units plus the weaning center. Logistic regression analysis found that male sex and respiratory history were independent predictors. Regarding mortality during hospitalization, logistic regression analysis found that decannulation was a protective factor. Another finding was that 80% of patients decannulated were discharged; only 15.8% of the group was not decannulated. The average survival was 45.47 months among the decannulated patients and 10.87 months for the non decannulated patients. Conclusions: We found that male sex and a history of respiratory failure were factors associated with unsuccessful decannulation. Decannulated patients had lower risk of death during hospitalization.
