Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Nasal irrigation with isotonic saline
Description: Infants were placed on the examination stretcher in the right or left lateral position. Then, 10 mL of isotonic saline solution was administered over 5 s into the upper nasal cavity of the infant. The secretion and irrigation solution from the lower nasal cavity were cleaned using gauze. The infant was placed on the other side, and the same procedure was repeated for the other nasal cavity. The infant was then placed in the prone position, and the tapotement technique was applied. The infant's mouth and nose were cleaned with gauze, completing the procedure.

Group type: EXPERIMENTAL
Intervention: Nontraumatic nasopharyngeal aspiration
Description: After nasal irrigation, the secretions and saline solution from the underlying nasal cavity were nontraumatically aspirated from the entrance of the nasal cavity after the irrigation. The infant was positioned on the other side, and the same procedure was repeated for the other nasal cavity. The infant was then placed in the prone position, and the tapotement technique was applied. The infant's mouth and nose were cleaned with gauze, completing the procedure.
