The Effect of Oral Colostrum Application on the Condition of the Mouth and Incidence of Late-Onset Sepsis Among Premature Infants: A Randomized Controlled Trial.

Background: Premature infants have higher risks of infection due to their underdeveloped immune systems and changes to the oral cavity's normal flora colonization.

Purpose: To assess the effect of oral colostrum application on the condition of the mouth and the incidence of late-onset sepsis (LOS) among premature infants.

Methods: In this randomized controlled trial, 70 newborn premature infants were randomly allocated to colostrum or sterile water groups. The Mouth Care Assessment Tool was used to evaluate the condition of the mouth for 5 days after oral colostrum application. The incidence of LOS was measured using clinical and laboratory indicators from 72 hours after birth until discharge.

Results: The condition of the mouth was significantly different on days 4 and 5, demonstrating that the colostrum group had less need for oral care ( P < .001) compared to the control group. There was no significant difference between the 2 groups in clinical symptoms and laboratory values related to LOS ( P > .05).

Implications for practice: Oral colostrum application can benefit oral mucosal health and reduce the need for oral care among premature infants. It is also safe alternative oral care for premature infants who cannot breastfeed during the first few days of life. Future research should include infants of different gestational ages and mechanically ventilated infants to assess the effect of oral colostrum application on serum immune factors.
