The trachea and bronchi of the newborn appear especially vulnerable to damaging effects from endotracheal tubes and suction catheters. Consequences of deep endotracheal suctioning include the development of bronchial stenosis and granulomas. Avoiding deep endotracheal suctioning minimizes these risks. Therefore when suctioning intubated infants after chest physical therapy (CPT), the therapist should not routinely advance the suction catheter beyond the distal end of the endotracheal tube. If evidence of persistent secretion retention exists despite adequate suctioning of the endotracheal tube, the suction catheter can be carefully and slowly advanced 1 or 2 cm beyond the tip of the endotracheal tube.
