Alternative Method of Apnea TestNCT01649726
Comparison of Two Strategies to Realize Apnea Test for the Diagnostic of Brain Death in Potential Organ Donors (CPAPNEE STUDY)
A study testing Apnea test - CPAP in people with Alternative Method of Apnea Test, run by Poitiers University Hospital at 13 sites in France.
Trial summary
Clinical diagnostic of brain death requires a non-reactive coma, absence of brain stem reflex, and absence of spontaneous breathing. The confirmation of absence of spontaneous breathing is established the apnea test (according to the American Academy of Neurology's Guidelines). Read more about this study

About this study
Clinical diagnostic of brain death requires a non-reactive coma, absence of brain stem reflex, and absence of spontaneous breathing. The confirmation of absence of spontaneous breathing is established the apnea test (according to the American Academy of Neurology's Guidelines). However this test may lead to complications (acute hypoxemia, ventilatory and cardiocirculatory disorders) and reduces significantly the number of lung transplants. Some data suggest modifying the apnea test : replace the ventilator switching off with continuous positive airway pressure (CPAP) use. These studies showed that this alternative method (CPAP) increased the level of lung harvest but they were not sufficient because these studies were monocentric, non randomized and with little patients,. That why the aim of the present study is to compare the standard strategy and CPAP strategy with a prospective, multicenter, randomized study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Clinical diagnostic of brain death requires a non-reactive coma, absence of brain stem reflex, and absence of spontaneous breathing. The confirmation of absence of spontaneous breathing is established the apnea test (according to the American Academy of Neurology's Guidelines). However this test may lead to complications (acute hypoxemia, ventilatory and cardiocirculatory disorders) and reduces significantly the number of lung transplants. Some data suggest modifying the apnea test : replace the ventilator switching off with continuous positive airway pressure (CPAP) use. These studies showed that this alternative method (CPAP) increased the level of lung harvest but they were not sufficient because these studies were monocentric, non randomized and with little patients,. That why the aim of the present study is to compare the standard strategy and CPAP strategy with a prospective, multicenter, randomized study.

Where is the study taking place?
The record lists 13 sites 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?

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?
Eligibility to donor lung harvest. 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?
