The failure of extubation in pediatric resuscitation is most often described as the need for reintubation within 48 hours after extubation. The failure rate of extubation in pediatric intensive care varies in the literature there is between 4 and 22% failures. These failures result in increased mortality, morbidity with a use of larger tracheostomy, a prolonged residence time. The extubation is codified in adult resuscitation and tends to be increasingly in pediatric resuscitation. In the pediatric intensive care unit of Hautepierre, a extubation protocol already exists for some time, and was prepared to go. the current literature data. It allows the harmonization of practices in service (previously left to the discretion of each doctor).

The investigators are looking to see if the protocol used systematically in the service enables a reduction in the incidence of occurrence of failures of extubation.
