Randomized Controlled Trial Clinical Trial
[VENISE: Non-invasive ventilation during mechanical ventilation weaning in chronic respiratory failure patients. A prospective randomised controlled and multicenter trial].
The clinical efficacy of non-invasive ventilation (NIV) has now been demonstrated in the management of acute-on-chronic respiratory failure (ACRF) in various etiologies. Endotracheal mechanical ventilation (ETMV) can lead to numerous complications and weaning difficulties increasing the risk of prolonged ETMV, morbidity and mortality as well as excess cost of intensive care. Therefore, it could be useful to consider NIV for delivering effective ventilatory support to reduce the length of ETMV in ACRF patients who are still not capable of maintaining spontaneous breathing. From the interesting but discordant results of two recent randomised controlled trials, a working group from the Société de Réanimation de Langue Française (SRLF) decided to perform a new prospective randomised controlled multicenter trial. The aim of the study will be to assess the usefulness of NIV as an extubation and weaning technique in ventilated ACRF patients. ⋯ Results of the VENISE trial should permit to improve the management of the difficult to wean ACRF patients and thus contribute to more precisely define the place of NIV in the weaning and prevention of re-intubation strategies in these patients.

The alveolar epithelium is the principal target in the course of acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) and to a lesser extent in chronic reactions like pulmonary fibrosis. ⋯ Our results obtained in humans suggest a beneficial role for neutrophils in the alveolar repair after acute or chronic lung injury. The experimental data suggest that use of KGF and HGF might be considered in the future in the treatment of human acute or chronic lung injury.
