prospective multicentre mixed methods study to explore extubation practices and respiratory outcomes in extremely preterm neonates.

Conditions: PreTerm Neonate; Extubation Readiness; Extubation Failure; Respiratory Morbidity; Bronchopulmonary Dysplasia; Mechanical Ventilation

Summary: the purpose of this observational study is to learn about neonatologists' perceptions of extubation readiness and extubation and reintubation practices in extremely preterm infants in the first 2 weeks of life using prospective qualitative and quantitative data. actual extubation readiness is defined as successful extubation, defined as no reintubation in the 7 days following extubation. key research questions are: how do clinicians assess extubation readiness in this population? does this assessment correlate with actual extubation success? what factors (reasons, clinical status, ventilatory parameters) are associated with extubation readiness? patients born before 28 weeks gestational age and admitted to the neonatal intensive care unit (nicu) within the first 24 hours are be included. the attending physician will complete a prospectively administered questionnaire with open-ended and multiple-choice questions to daily assess the decision and rationale for extubation or non-extubation of patients mechanically ventilated during the first 15 days of life. patient characteristics, respiratory outcomes, and mortality will be recorded until the end of hospitalisation and/or definitive weaning from any ventilatory support or supplemental oxygen.

with prolonged stays in the neonatal intensive care unit (nicu) and significant respiratory morbidity, respiratory management of the most premature newborns - born before 28 weeks gestational age (ga) - brings a number of challenges. despite recommendations to give priority to non-invasive ventilation in cases of respiratory insufficiency, recent studies show that over 80% of these newborns receive mechanical ventilation (mv) at least once in their nicu course, most within the first week of life (100% if born at 23 sa, \>90% at 24 and 25 sa, \>80% at 26 and \>70% at 27 weeks ga). several studies have shown that a longer cumulative duration of mv is associated with a worse respiratory and neurodevelopmental prognosis in this population. early extubation is therefore recommended. however, extubation failures in patients born at these early stages of life are common and are per se associated with respiratory morbidity. extubation failure is defined in the literature as reintubation within days of extubation. a delay of 7 days after extubation has been identified as the time frame for capturing extubations related to respiratory causes. in a french study, using the sepreven cohort for patients born before 27 weeks' ga, extubation failure at 3, 7 and 15 days concerned 25%, 33% and 50% of patients respectively. the decision to extubate a premature patient is a complex one, but contributes in part to the patient's outcome. shalish referred to the concept of "extubation readiness dilemma" to indicate the uncertainty surrounding the clinical features associated with successful extubation. identifying a state for each patient that allows successful extubation, without reintubation in the following days, is most often based on ward routines in which assessments of the infant's respiratory capacity are taken into account. medical literature doesn't provide recommendations on extubation criteria, and practices differ from one unit to another. the aim of this study is to provide a detailed description of extubation practices and failures in several nicus in france, based on a prospective collection of qualitative and mixed data.
