Evaluation of the Ability to Diagnose the Position of the Intubation Probe Thanks to Lung Ultrasonography

Oesophageal intubation can cause death. Selective intubation can induce a poor ventilation, hypoxemia, atelectasis etc… It's not rare in paediatric intubation. The prevalence of malposition of endotracheal tube is 30 to 40% in babies and infants less than 1 year old. Currently doctors try to detect malposition of intra-tracheal tube by auscultation and capnograms and chest radiography is needed to confirm it. The Chest X ray is the gold standard. The aim of the study is to confirm the good positioning of the tube with a lung ultrasonography. After each intra-tracheal intubation, for patients with qualifying criteria, a lung ultrasonography will be performed, in bed, by two trained doctors (senior and junior) to determine if the position is right. Then, the chest radiography will be performed as usual.
