Обзор
Weaning-induced pulmonary edema (WIPE) from the ventilator is a frequent cause of extubation failure or delay, which prolongs the duration of invasive mechanical ventilation and the associated morbidity and mortality. WIPE is a very frequent cause of extubation failure in at-risk patients. A spontaneous breathing trial (SBT) is performed before extubating a patient, either by disconnecting the patient from the ventilator (T-piece SBT) or by setting the ventilator to spontaneous breathing mode with pressure support at 7 cm H2O and zero positive end-expiratory pressure (PS-ZEEP SBT). There is currently no recommendation regarding which SBT modality should be used, particularly in patients at risk of WIPE. The hemodynamic changes induced by the SBT can lead to WIPE, which typically develops within minutes of the SBT onset. The hypothesis being tested is that, by altering intrathoracic pressure during the patient's inspiration (negative pressure), the T-piece SBT leads to a greater increase in left ventricular filling pressures compared to the PS-ZEEP SBT.
Вмешательства
- Процедура T-piece SBT
T-piece SBT will be evaluated first and PS-ZEEP SBT in a second time. If the first SBT fails, regardless of the modality used or the cause of failure, the second SBT will not be performed. The patient will then be managed according to the participating centers' standard of care (treatment guided by the main mechanism of WIPE identified by echocardiography). The two SBTs will be separated by at least 6 hours, during which no therapeutic changes will be made (in case of success at the first SBT). - Процедура PS-ZEEP SBT
