For the newborn nasal secretion, parents can use the following methods to clean: 1, the application of cotton swabs dipped in water to clean, if the newborn secretion is very dry, parents should be slightly dipped in some water, soften the cotton swabs and then gently rotate, so as to take out the secretion. Because if the parents’ action is very rough, it is easy to cause damage to the mucous membrane of the nasal cavity; 2, the application of glycerin to clean, if the secretion is particularly dry, it is difficult to soften the application of water, in this case we should apply glycerin. Because glycerin has a good lubricating effect, not only can effectively soften, but also ensure that the newborn’s nasal mucosa moist, so as to prevent nasal bleeding and so on.
