Incidence of Weaning-induced Pulmonary Oedema (The WIPO Study)
In Brief
An observational study evaluating Spontaneous breathing trial for Weaning Failure and 2 related conditions. Completed, enrolled 500 participants across 1 site.
Detailed Summary
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.
Study Details
Timeline
Interventions
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.
