Randomized crossover trial of endotracheal tube suctioning systems use in newborns.

Background: Maintaining endotracheal tube patency is critical for neonates receiving mechanical ventilation. Endotracheal tube suctioning removes accumulated secretions preventing potential adverse events, however is also potentially hazardous to the patient.

Objective: To compare respiratory rate, arterial blood oxygen saturation, heart rate and pain in newborns undergoing endotracheal tube suctioning with closed (CS) and open (OS) systems.
