Effects of Non-Traumatic Nasopharyngeal Suction Technique in Infants

A modified suctioning technique that avoids deep catheter insertion and minimizes mucosal contact. Sterile saline (0.9%) is instilled into one nostril, and secretions are aspirated using external suction via the opposite nostril or mouth. This approach is designed to reduce pain and physiological stress compared to standard suction methods in preterm infants undergoing non-invasive ventilation.
