Study 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.

Read the detailed description

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.

Interventions

  • Devicelow 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

    Also known as: non fenestrated TRACOE® twist, TRACOE tracheostomy tubes with low-pressure cuff, low wall thickness and a good fit of the inner cannula in the outer cannula

Start is estimated for Sep 2024; primary completion for Oct 2026, 25 months later.

Of 212 non-industry interventional studies with no phase under Dyspnea, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 28. This study's planned 25 months is above that.

Counting every sponsor, half of 226 studies reached it within 14 months; a quarter within 6 and three quarters within 28.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
