The Effect Of Oral Motor Stimulation And Nonnutritive Sucking To The Time Of Transition To Oral Nutrition In Preterm

Oral feeding difficulty is one of the problems that preterm infants frequently experience due to poorly developed oral musculature. Sucking and swallowing are present in early fetal life, but sucking-swallowing and swallowing-respiratory coordination are respectively occurs after the 32 and 33-34 gestational week (GA). For this reason, although there are sucking movements in preterm babies with gestational weeks of 31 and below, oral feeding is difficult because adequate coordination cannot be achieved during sucking-swallowing and breathing. Until these structures develop, preterm babies are fed by gavage (nasogastric/orogastric route) in intensive care units. Gavage feeding causes many negativities such as preventing the advantages of oral nutrition and creating an entry route for infectious agents, and the discharge is also delayed. Thus, infants are exposed to adverse intensive care conditions for a longer period of time. For this reason, it is important to ensure the transition to full oral nutrition as soon as possible. There are various methods that facilitate the transition of infants to oral feeding. Pacifier and oral stimulation applications are some of them. Oral stimulation was first applied by Fucile et al (2002). It is a method consisting of a total of 15 minutes, in which therapeutic touches are made for 12 minutes before feeding, and in the last few minutes, non-nutritive sucking is applied. Later, Lessen thought that this intervention was longer than the fragile preterm babies with a small oral cavity and shortened the duration of the intervention and reformatted it. This intervention, called "Premature Infant Oral Motor Intervention (PIOMI)" (Preterm Infant Oral Motor Intervention), is a 5-minute application consisting of 3 minutes of massage and 2 minutes of non-nutritive sucking. In the literature review, a study comparing oral motor stimulation and pacifier method was reached. However, in this study, unlike our study, a pacifier was applied to one of the groups, a 12-minute stimulation to the second, and a 12-minute stimulation and pacifier to the third. In our study, there are 3 groups. one of the groups a pacifier will be applied to one group and a 5-minute oral stimulation program will be applied to the other group. The third group is the control group. The aim of the study is to evaluate the effect of pacifier and oral stimulation applied to preterm infants on the transition time to oral feeding.

The infant hospitalized in the intensive care unit will be evaluated primarily in terms of inclusion criteria in the sample group. The baby meeting the criteria will be evaluated by the neonatologist physician and, if appropriate, interviewed with the parents. Parents will be informed about the study and their written consent will be obtained. The group that the baby will be included in will be determined by the randomization method. "Preterm Baby Information Form" created by the researcher will fill to all infants in the before the intervention. Then, body weight, height and head circumference will be measured and recorded in order to fill in the 1st day anthropometric measurements information in the Preterm baby follow-up form. Then, "Early Nutrition Skills Assessment Tool (EFS-Turkish)" will be applied to evaluate pre-intervention nutrition skills. Then, intervention will be started. Infants in the PIOMI group will receive a 5-minute PIOMI 30 minutes before feeding time. Infants in the non-nutritive sucking group will receive pacifier 3 minutes before 1 hour any feeding time and, 2 minutes before 10 minutes. PIOMI and non-nutritive sucking will be applied once daily for 14 days. only feeding follow-up will be done in the infants in the control group. "Early Feeding Skills Assessment Tool (EFS-Turkish)" will be re-administered to all babies at the end of the fourteenth day. Nutritional follow-up will be done until the babies are discharged. In nutritional follow-up will be evaluated time to transition to full oral feeding and how many cc it takes per minute.
