Summary

This trial aims to assess dyspnea intensity in tracheostomized patients undergoing prolonged artificial ventilation weaning. The primary outcome is dyspnea measured by the Visual Analogue Scale (VAS-Dyspnea). A comparison between low-pressure balloon tracheostomy cannula and plated balloon cannula and four interfaces (Cap, ventilator, phonation valve, or filter) are tested. The secondary outcomes including Multidimensional Dyspnea Profile, pain, anxiety VAS, and tolerance under different interfaces. The multicenter, cross-over study involves 76 patients over 25 months, each serving as their own control. Cap is always evaluated first but the order of the three interfaces (ventilator, phonation valve, or filter) and type of cannula are chosen by randomization. The study is conducted in three weaning centers (SRPR units) at Pitié-Salpêtrière, Bligny, and Forcilles.

Conditions

  • Prolonged Weaning

Interventions

DEVICE

low pressure tracheostomy cannulas

The tracheostomy tube is changed according to the randomization sequence, a filter is connected for 5 minutes; then baseline data will be assessed. The tracheostomy tube is then connected to the four interfaces for 30 minutes each. Parameters is measured after each 30-minute period. The cuff of the tracheostomy tube will be deflated using a syringe when the interface is a filter, phonation valve, or cap. In contrast, the cuff will be inflated when the interface is the ventilator. The cuff is inflated with a manometer for the low-pressure balloon tracheostomy tube and with the minimum and sufficient amount of injectable water for the plated balloon tracheostomy tube to avoid overpressure
