Effect of premature infant oral motor intervention [PIOMI] combined with music therapy on feeding progression of preterm infants: a randomized control trial

Abstract

Prematurity may produce long-term complications in the physical and cognitive development of infants. There is a need for interventions that can improve feeding and reduce the length of NICU stay and separation time between the infant and mother. This study aimed to explore the clinical effect of premature infant oral motor intervention [PIOMI] combined with music therapy [MT] on feeding progression in premature infants.Premature infants with gestational ages between 26 and 30 weeks were included in the study. Fifty-two participants were randomly divided into intervention and control groups. All infants received PIOMI, and the intervention group received additional MT. The participants of the two groups were compared based on weight gain, feeding progression, Preterm Oral Feeding Readiness Scale [POFRAS], milk volume, and length of hospitalization. The data were analyzed using independent sample t-tests, covariance tests, and repeated measure ANOVA used to compare three group means.The intervention group reached independent oral feeding 8 days earlier [P = .018] than the control group. Length of hospitalization was 6 days shorter [P = .224] for the intervention group, and the mean volume of milk on the 10th day was 215.38 ± 56.4 in the intervention group and 155.69 ± 68.9 in the control group, respectively [P = .001]. The mean score of the POFRAS scale on the 10th day was 28.65 ± 3.0 in the intervention groups and 20.96 ± 3.3 in the control groups, retrospectively [P = .001]. There was no difference in weight gain between the two groups [P = .522].Conclusion: PIOMI combined with MT was effective for the feeding progression of premature infants, and infants who received both these interventions were discharged sooner than control infants. Thus, MT should be considered part of feeding interventions for preterm infants with gestational ages between 26 and 30 weeks.Trial registration: Clinical trial registration number: IRCT20210502051155N1 on 18/9/2021 What is Known -- What is New: • There is numerous study about the eff ect of music therapy or oral motor interventi on. However, premature Infants havenot been yet studied to determine whether music therapy and oral motor interventi ons may synergize to aid their feedingprogression.
