[Predictors of weaning and mortality in prolonged mechanical ventilation – surviving survival].
Rev Fac Cien Med Univ Nac Cordoba
June 2022
Objetive: to describe a sample of tracheostomized patients requiring prolonged mechanical ventilation who were admitted to a weaning center, to analyze their evolution and to determine the predictors of weaning failure from mechanical ventilation and of mortality. Design:
Design: an observational and retrospective cohort study was carried out, in the period between January 2005 and December 2017. Setting: weaning and rehabilitation center.
Background: Prolonged mechanical ventilation is increasingly common in ICUs. Although a consensus conference defined weaning success in this patient population, few studies have used this definition. A clear definition of successful weaning is useful to assess clinical and epidemiological outcomes, facilitate clinical decision making, and set goals of care.

Background: Our objective was to describe the prevalence and characteristics of tracheal lesions observed in flexile bronchoscopies of tracheostomized patients, and to determine those factors associated with severe injuries.
Methods: This is an analytical, observational, and transversal study. The flexible bronchoscopies of tracheostomized patients from our database were reviewed to assess their lesions.
Effect of tracheostomy tube on work of breathing: Comparison of pre- and post-decannulation.
Int J Crit Illn Inj Sci
January 2016
Objective: To describe and compare the work of breathing (WOB) during spontaneous breathing under four conditions: (1) breathing through a tracheostomy tube with an inflated cuff, (2) breathing through the upper airway (UA) with a deflated cuff and occluded tube, (3) breathing through the UA with an occluded cuffless tube, and (4) postdecannulation.
Patients And Methods: Patients who tolerated an occluded cuffless tube were included. Ventilatory variables and esophageal pressure were recorded.
Article Synopsis
- The study focuses on cuff pressure (CP) variations in tracheostomized patients who are not on mechanical ventilation, which is an area that has been under-researched.
- An experimental setup tested the performance of pressure gauges on different tracheostomy tubes, while a clinical setup measured CP variations over 6 days in 35 stable patients.
- Findings revealed significant differences in cuff pressures across tube brands and types, with a notable variability in measurements, indicating that more frequent monitoring of CP in these patients is necessary.
