Nasal mucociliary function in the normal newborn

Nasal mucociliary transport has been studied using the seroalbumin-Tc99m radioisotope method in 10 adults and 10 normal newborns under 28 days of age. The mean transport velocity was 8 and 6 mm/min for the normal adults and newborns, respectively, with no significant differences between the two (P = 0.07).
