About this study
Official title: Incidence of Weaning-induced Pulmonary Oedema (The WIPO Study)
During weaning from mechanical ventilation, the shift from positive to negative pressure ventilation may be responsible for a cardiac dysfunction that can lead to the development of pulmonary oedema (weaning-induced pulmonary oedema, WIPO) and to the failure of spontaneous breathing trials. However, the incidence and risk factors for WIPO development are not well defined and have been investigated only by a few studies.
Read the detailed description
During weaning from mechanical ventilation, the shift from positive to negative pressure ventilation may be responsible for a cardiac dysfunction that can lead to the development of pulmonary oedema (weaning-induced pulmonary oedema, WIPO) and to the failure of spontaneous breathing trials. The mechanisms leading to WIPO have been described in many studies. The fact that the intrathoracic pressure becomes negative increases right ventricle preload and afterload, reduces right ventricle compliance and increases left ventricle afterload. Arterial hypertension, which results from adrenergic stress and possibly from hypercapnia, usually worsens this latter mechanism. Myocardial ischemia, resulting from the imbalance between the reduction of oxygen delivery (hypoxemia) and increased oxygen demand (unfavourable loading conditions, increase of inotropic and heart rate) may participate in this phenomenon, even though its incidence seems to be low. The means for detecting WIPO in a patient performing a spontaneous breathing trial (SBT) have been widely investigated. To avoid the insertion of a pulmonary artery catheter, which clinicians nowadays tend to avoid when the patient is ready to be extubated, many alternatives methods have been proposed. The increase of left ventricular filling pressure during an SBT was detected with echocardiography, the increase during the test either of B-type natriuretic peptide levels or of extravascular lung water measured by transpulmonary thermodilution can be used. The investigators have also demonstrated that the detection of haemoconcentration during a weaning test, which is related to the filtration of a significant amount of plasma through the alveolar-capillary barrier, allows the detection of WIPO.
Unresolved questions:
The incidence of WIPO is not well defined. In the studies where it has been reported, it ranged between 44% and 87% of SBT failures. However, these studies included a small number of patients and/or included a specific population of patients that had already failed one or more weaning tests. In a monocentric study, the investigators recently reported that WIPO occurred in 59% of cases of SBT failures.
The risk factors for WIPO development are not well defined and have been investigated only by a few studies. In the above-mentioned one, the investigators have identified the presence of pre-existing cardiopathy, pre-existing chronic respiratory failure and obesity as independent risk factors for developing WIPO. However, these results were obtained only from a monocentric cohort.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Spontaneous breathing trialProcedure or surgery
A spontaneous breathing trial (SBT) is used to identify patients who are likely to fail liberation from mechanical ventilation. The test can be done according to the usual modalities of the participating centre, following the international recommendations, meaning either by disconnecting the endotracheal tube from the ventilator and connecting it to a source of oxygen through the T-tube or by setting pressure support with low positive end-expiratory pressure (PEEP). The choice of the method will not be determined according to the participation in this study but will be done according to the habits of the participating centre.
What is being measured
The primary outcome is the main question the study is designed to answer.
The incidence of WIPO
The diagnosis of WIPO will be done a posteriori by a group of experts. They will establish the diagnosis of WIPO, based on the following elements:
- Failure or success of SBT
- Clinical examination at the end of SBT
- Variation during SBT of arterial blood gas variables, plasmatic protein and blood haemoglobin concentration, extravascular lung water (optional), B-type natriuretic peptide (optional), echocardiographic estimation of left ventricular preload (E and A waves of mitral flow, e' wave of the mitral valve annulus), pulmonary arterial occlusion pressure (optional).
Measured: 30-120 mins during the Spontaneous Breathing Trial
Secondary outcomes (1)
Risk factors for developing WIPO
Measured: The risk factors for WIPO will be done a posteriori by multivaraite analysis

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
During weaning from mechanical ventilation, the shift from positive to negative pressure ventilation may be responsible for a cardiac dysfunction that can lead to the development of pulmonary oedema (weaning-induced pulmonary oedema, WIPO) and to the failure of spontaneous breathing trials. However, the incidence and risk factors for WIPO development are not well defined and have been investigated only by a few studies.

Questions about this trial
What is this clinical trial studying?
An observational study of Weaning Failure and Weaning-induced Pulmonary Edema, run by Bicetre Hospital 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 3 inclusion and 2 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 16 Nov 2022. 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?
The incidence of WIPO (time frame: 30-120 mins during the Spontaneous Breathing Trial). 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 NCT05318261, which also lists 13 linked publications.
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 16 Nov 2022.
