Gien J, et al. - Here, the authors determine whether endotracheal tube (ETT) insertion depth should be modified in infants with a congenital diaphragmatic hernia (CDH) to reduce the risk of main-stem intubation. In infants with CDH, cephalad displacement of the carina can predispose them to right main-stem intubation and subsequent development of pneumothorax. They consider that modifying the ETT insertion depth to 5.5 cm + weight in newborns born at term can prevent pneumothoraces and improve outcomes for infants with CDH.
