Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Dyspnea is common in patients ventilated in intensive care and SRPR units, and it can generate states of post-traumatic stress. Due to the prolonged duration of artificial ventilation, tracheostomized patients, for the purpose of prolonged weaning from artificial ventilation, are particularly exposed to dyspnea.

The main objective is to compare the respective impact of a low-pressure balloon tracheostomy cannula and a plated balloon cannula on the dyspnea intensity of tracheostomized patients in spontaneous ventilation, with the cannula closed by a cap. The primary outcome is the Visual Analogue Scale (VAS) for dyspnea (VAS-Dyspnea).

The investigators will compare low pressure versus plated balloon tracheostomy cannulas, considering the sensory and emotional components of dyspnea, as well as tolerance, pain, comfort, and anxiety under four different interfaces: ventilator, phonation valve, Cap, or filter. This will be measured through the following secondary outcomes:

* VAS-Dyspnea
* Multidimensional Dyspnea Profile
* Pain and anxiety VAS This multicenter study (SRPR Pitié-Salpêtrière, Bligny, and Forcilles) will be randomized in a cross-over design, comparing the use of two types of low-pressure or plated balloon cannulas over two consecutive days. For each cannula, four interfaces will be connected in a row starting with the cap. The order in which the other three interfaces will be set up will be randomized (ventilator, filter, and phonation valve).

It is a cross-over including 76 patients, with each serving as their his own control, over 25 months.

4 interfaces are tested: cap, ventilator, filter and phonation valve

Group Type EXPERIMENTAL

low pressure tracheostomy cannulas

Intervention Type DEVICE

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
