Nasal mucociliary transport in pregnancy.
Using the saccharin method, we performed tests of mucociliary function four times during pregnancy and once one month after delivery in 27 women. As the transport distance for saccharin varied from 37 to 65 mm, we used the transport speed for evaluation. Pregnancy rhinitis affects at least 20% of pregnancies. The mucociliary transport speed was higher in the group of women with pregnancy rhinitis, and was reduced during pregnancy in the group of women without that condition. We found no significant correlation between mucociliary transport speed and objectively registered nasal peak expiratory flow index. The pathophysiology of pregnancy rhinitis is not known, but is possibly multifactorial. The changes occurring in the nasal mucociliary transport system during normal pregnancy and in pregnancy rhinitis need further studies.
