Abstract
Mechanical ventilation is the mainstay of management of a variety of conditions affecting the neonate. The endotracheal suctioning of ventilated neonates is necessary for removing secretions and improving adequate alveolar ventilation. It is usually performed through open suction system where the patient is disconnected from the ventilator and the suction catheter is introduced into the endotracheal tube. Although, tracheal suctioning is frequently performed to clear airway secretion, open suction system (OSS) is associated with a number of complications. So, advanced suctioning technique namely closed suction system (CSS) has been introduced into clinical practice with the aim of preventing or reducing the unwanted effects of OSS. In CSS the suction catheter is usually introduced into airway without disconnecting the patient from the ventilator so, the risk of complications may be reduced by minimizing the interference with ventilation during the procedure.
