Intubação seletiva do brônquio principal esquerdo em unidade de terapia intensiva neonatal

Urgent intubation of the left mainstem bronchus with an endotracheal tube can be easily achieved by recognizing that it is the position of the endotracheal tube tip and the direction of its concavity that are the chief determinants of which bronchus an endotracheal tube goes when advanced. This is important in critically ill neonates as the margin of safety and time window are small, and the absence of double‐lumen tubes. Use of fiberoptic bronchoscope and blockers should be reserved as backup plans.
