About this study

Official title: Comparison of Two Methods for Assessing Cough Capacity in Intensive Care Unit After Cardiac Surgery: Parietal Ultrasound vs. Peak Expiratory Cough Flow

Weaning from mechanical ventilation represents 50% of the time spent under mechanical ventilation (1). The risk factors identified in the failure to wean from mechanical ventilation are:

  • left heart dysfunction with LVEF < 30%.
  • an ineffective cough
  • presence of resuscitation neuromyopathy
  • mechanical ventilation time >7 days
  • presence of a delirium
  • age >65 years old
  • abundant bronchial secretion
  • presence of underlying lung pathology An ineffective cough is found in 40% of patients requiring reintubation. However, cough assessment is most often approximate, based on a subjective assessment of cough strength by asking the patient to cough spontaneously on his or her tube).

The objective evaluation of cough is based on the measurement of the peak expiratory flow rate at cough, commonly referred to as peak expiratory flow rate at cough (PEFD), the patient is asked to take a deep breath and then cough as hard as possible.

Subjective cough assessment does not predict the occurrence of ventilatory withdrawal failure. Conversely, all studies that objectively assessed the strength of cough before extubation by measuring the PEFD found a significant association with the outcome of extubation: a low PEFD increases the risk of extubation failure by a factor of 5 to 9.

The investigators hypothesize that the increase in parietal abdominal muscle contraction obtained by using a non-invasive ultrasound method indicates an effective cough. Conversely, an ineffective cough can be detected by this simple ultrasound criterion, which can be performed at the patient's bedside and extrapolated to all intensive care units equipped with an ultrasound scanner. This evaluation will be carried out before extubation: during the spontaneous ventilation test on a tube in a half-seated position (>45°) and within 24 hours after extubation.

What is being measured

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

  1. parietal ultrasound

    compare parietal ultrasound with peak expiratory flow rate measurement (PEFD) in patients ventilated less than 48 hours after cardiac surgery with a sternal approach.

    Measured: 48 hours

  2. peak expiratory flow rate

    compare parietal ultrasound with peak expiratory flow rate measurement (PEFD) in patients ventilated less than 48 hours after cardiac surgery with a sternal approach.

    Measured: 48 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Intensive Care Unit and Cardiac Surgery, run by Centre Chirurgical Marie Lannelongue at 1 site in France.

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 5 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: finished, as of the sponsor's last update on 23 Jan 2020. 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 France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

parietal ultrasound (time frame: 48 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Jan 2020.
