The Effect of Oral Motor Stimulation on the Transition to Full Oral Feeding, Breastfeeding, and Length of Hospital Stay in Preterm Infants.

Objective: To determine the effect of oral motor stimulation (OMS) applied to preterm infants on their sucking and swallowing abilities to establish a successful and safe oral feeding experience. Methods: A pre-post intervention study was conducted between December 2019 and December 2020, which included preterm infants born at <35 weeks of gestational age and admitted to the neonatal intensive care unit. Patients with major congenital abnormalities (including cardiac, facial, and jaw deformities), severe NEC, stage 3-4 IVH were excluded from the study. Patients who received OMS by a speech and language therapist between June 2020 and December 2020 were assigned to Group 1, while patients who received no intervention between December 2019 and May 2020 were assigned to Group 2. The time to achieve full oral feeding (FOF), acquisition of breastfeeding rates at discharge, and the length of hospital stay (LOS) were compared between the groups. Results: A total of 62 patients were included in the study (31 in Group 1 and 31 in Group 2). There were no significant differences in birth weight and demographic data between the groups. The mean time to achieve FOF was found to be significantly shorter in Group 1 (31 ± 23.6 and 46.7 ± 22.3 days, respectively, p = 0.013). The mean LOS was also found to be shortened with a mean duration of 10 days in Group 1, without statistical significance (56.4 ± 35.3 days versus 66.0 ± 42.9 days, respectively, p = 0.34). Acquisition of breastfeeding rates was significantly higher in the intervention group (p < 0.05) Conclusions: OMS accelerates the transition to FOF in preterm infants and increases the rates of acquiring breastfeeding skills at discharge.
