Iatrogenic lesions of the upper airway in the newborn.
A retrospective study of 140 babies who survived the first week of life and who had endotracheal intubation showed that 65 of them had either or both of the following complications of endotracheal tube therapy: (a) Collapse of one or more lobes with the tube in place or within the first two days following extubation and lasting less than 24 hours. When collapse lasted more than 48 hours, it often required repeated intubation for tracheal cleansing. The right lung, especially its upper lobe, was predominantly affected. (b) Tracheal lesions and nasal necrosis. A statistical comparison with intubated babies of similar age without complications showed the following factors to predispose to lobar collapse: younger gestational age, maximal high oxygen concentration administered, and prolonged duration of intubation. The results of endotracheal tube cultures bore no relation to the complication rate.
