The Effects of "Oral Administration of Breast Milk Droplets" and "Palatal Stimulation With a Finger" Methods on Feed Tolerance in Preterm Newborns Fed Via an Orogastric Tube

This is a randomized, controlled and experimental study investigating the effects of "oral administration of breast milk droplets" and "finger palatal stimulation" methods on feeding tolerance in infants fed with an orogastric tube.The study included 90 premature infants who were 28-36 weeks of gestation, admitted to the neonatal intensive care unit and whose parents consented to participate. Two intervention groups (Intervention1 and Intervention2) consisted of a total of 60 infants and the control group consisted of 30 infants. A power analysis was conducted to calculate the number of premature infants to be included in the study. We created the randomization table using the instructions in the following link: "https://www.calculatorsoup". The study was completed with 90 newborns who met the inclusion criteria and whose parents consented to participate. Of these newborns, 60 were in the intervention group and 30 were in the control group. Data were collected using the "Demographic Information Form" and "Patient Follow-up Form" developed by the researcher in line with the literature.

Study Execution

Pre-Procedure: The steps before the procedure were the same for each group, i.e. the oral administration of breast milk droplets group, the palatal stimulation group and the control group. Before the procedure, the subjects' identities were checked and the Demographic Information Form (gender, gestational week, birth weight, head circumference and height) and Patient Follow-up Form were completed. The newborns in all groups were placed on an orogastric tube, positioned, and finally the infants' heads were gently lifted from the bed at a 30-degree angle. After achieving the correct position, their remains were checked and the results were noted. The stomachs of all premature infants included in the study were checked every 3 hours before feeding for 7 days.

Sequence of Procedures: Infants in the oral administration of breast milk droplets group were fed with an oroastric catheter after a total of 0.5 cc of breast milk was administered in drops using an insulin syringe for 5 minutes. In the palatal stimulation group, the palate and gums were stimulated with slow and peristalsis-like movements for 5 minutes with the gloved pinky finger of one hand while the infants were fed with an orogastric catheter, following the necessary hygiene rules. Premature infants in the control group were fed with orogastric catheter by following all hygiene rules, but no intervention was performed. Intervention groups received intervention for 5 minutes every 3 hours during feeding hours for 7 days.

Post Procedure: After feeding, all infants received routine comfort care, including diaper care, positioning, and environmental adjustments (adjusting sound and light levels, etc.). After routine comfort care, defecation was examined in all subjects every day during the 7-day follow-up period and the results were recorded. At the end of each day, the abdominal circumference and body weight of the newborns were measured and the measurements were noted on the forms. SPSS (Statistical Package for Social Sciences) 22.0 for Windows software was used for statistical analysis. Number, percentage, mean and standard deviation were used in descriptive statistical methods. Differences between the rates of categorical variables in independent groups were analyzed using the chi-square test and Fisher's exact test. One-way Analysis of Variance was used to compare quantitative continuous data between groups. Repeated Measures ANOVA Test was used for within-group comparisons.
