The aim of this study was to investigate the impact of oropharyngeal mother's milk administration on salivary secretory immunoglobulin A (sIgA) levels in preterm infants fed by gastric tube. The results showed that oropharyngeal mother's milk administration can improve the salivary sIgA levels of preterm infants.
The aim of the present study was to explore the effect of oropharyngeal mother's milk administration on salivary secretory immunoglobulin A (sIgA) levels in preterm infants fed by gastric tube. Infants (n = 130) with birth weight < 1500 g were randomly allocated into two groups which both received breast milk for enteral nutrition. The experimental group (n = 65) accepted oropharyngeal mother's milk administration before gastric tube feeding for 14 days after birth. The control group (n = 65) accepted oropharyngeal 0.9% normal saline administration. Saliva concentration of sIgA were assessed at the 2 h, 7th and 14th day after birth. The level of salivary sIgA in experimental group were significantly higher than those in control group on the 7th day after birth (p < 0.05), but there were no differences in salivary sIgA levels on the 14th day between the two groups. The results of quantile regression analysis showed that oropharyngeal mother's milk administration, delivery mode and gestational age had significant effects on the increase of sIgA. SIgA in experimental group and the total number of intervention had a significant positive correlation (p < 0.05). Oropharyngeal mother's milk administration can improve salivary sIgA levels of preterm infants.
