Abstract
Objectives
This study was performed to evaluate the effect of oral stimulation with breast milk for preterm infants.
Methods
A total of 68 subjects form neonatal intensive care unit were randomly assigned into control group (n=20), premature infant oral motor intervention (PIOMI) group (n=25) and premature infant oral motor intervention with breast milk (BM-PIOMI) group (n=23).
Results
BM-PIOMI group had significant shorter initiation of oral feeding (IOF) time compared to PIOMI group (2.95 days, 95% CI [0.42–5.48]) or control group (9.79 days, 95% CI [7.07–12.51]). BM-PIOMI group had significant sooner transition time from IOF to full oral feeding (FOF) compared to control group (6.68 days, 95% CI [2.2–11.16]), but not to PIOMI group (2.09 days, 95% CI [−2.07 to 6.25]). Length of hospital stay (LOS) did not show statistical different between three groups (control 38.85 ± 14.40 vs. PIOMI 38.48 ± 11.76 vs. BM-PIOMI 38.04 ± 12.2). Growth mixture model identified improvement in non-nutritive sucking (NNS) score in BM-PIOMI group compared to control and PIOMI group (0.8293, p<0.0001, and 0.8296, p<0.0001, respectively).
Conclusions
Oral stimulation with breast milk can better promotes the oral feeding process of premature infants than the simple oral stimulation, by shorten IOF time and improve early NNS score, but does not shorten transition time from IOF to FOF and LOS.
