Trial summary

Weaning from mechanical ventilator is an essential element in the care of critically ill intubated patients receiving mechanical ventilation. It covers the entire process of liberating the patient from mechanical support and from endotracheal tube. The process of weaning involves two-step strategies: 1. Read more about this study

About this study

Weaning from mechanical ventilator is an essential element in the care of critically ill intubated patients receiving mechanical ventilation. It covers the entire process of liberating the patient from mechanical support and from endotracheal tube.

The process of weaning involves two-step strategies: 1. Assessment of readiness for weaning, including physiological measurement, such as maximum inspiratory pressure, tidal volume, respiratory rate and etc. 2. Spontaneous breathing trial.

Tracheostomy has become an increasingly common intervention in ICUs, especially for patients with prolonged mechanical ventilator support.

Tracheostomy may reduce work of breathing by improving some aspects of pulmonary mechanics, such as reducing dead space and decreasing airway resistance, but to date, there is no evidence that this is linked to reduction in weaning time or length of stay.

The investigators believe such improvement in pulmonary mechanic, which may reflect in the weaning parameter that respiratory therapist measured before weaning program, may be different from that measured before tracheostomy creation.

The investigators therefore hypothesized that the improvement in pulmonary mechanic for patients with weaning failure after tracheostomy may reflect on weaning parameters, and that this improvement may be able to predict the subsequent successful weaning from mechanical ventilator support.

Hereby the investigators perform a prospective single-center study to investigate the changes of weaning parameters in difficult weaning patients after tracheostomy as a predictor of subsequent successful weaning.

Read the detailed description

Weaning from mechanical ventilator is an essential element in the care of critically ill intubated patients receiving mechanical ventilation. It covers the entire process of liberating the patient from mechanical support and from endotracheal tube1. The process of weaning involves two-step strategies: 1. Assessment of readiness for weaning, including physiological measurement, such as maximum inspiratory pressure, tidal volume, respiratory rate and etc. 2. Spontaneous breathing trial. The incidence of successful weaning is estimated around 68.8%.

Despite there is no consensus on the optimal timing of tracheostomy, patients with prolonged trans-laryngeal intubation are finally succumbed to tracheostomy, as prolonged trans-laryngeal intubation causes tissue trauma, promotes bacterial translocation and infection, making tracheostomy an increasingly common intervention in ICUs. Meanwhile, tracheostomy may reduce work of breathing by improving some aspects of pulmonary mechanics, such as reducing dead space and decreasing airway resistance, but to date, there is no evidence that this is linked to reduction in weaning time or length of stay.

We believe such improvement in pulmonary mechanics, which may reflect in the weaning parameters that respiratory therapist measured before weaning program, may be different after tracheostomy creation, especially in those patient with weaning failure. We therefore hypothesized that there may be an improvement in pulmonary mechanic for patients with weaning failure after tracheostomy, and that this improvement may be able to predict the subsequent successful weaning from mechanical ventilator support. Hereby the investigators perform a prospective single-center study to investigate the changes of weaning parameters in weaning failure patients after tracheostomy as a predictor of successful weaning.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes of weaning parameters after tracheostomy

    Weaning parameters are measured before and after tracheostomy creation too see if there is any changes

    Measured: 5 days

Secondary outcomes (1)
  1. To evaluate if changes in weaning parameters will predict successful weaning

    We will first measure the changes of weaning parameters after tracheostomy. If changes do occur, we would like to evaluate if it will predict subsequent weaning feasibility.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Weaning Failure, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jih-Shuin Jerng, MD, PhD (0972651075, jsjerng@ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes of weaning parameters after tracheostomy (time frame: 5 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01312142, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Dec 2011.
