Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The population of the study will consist of preterm infants admitted to the Neonatal Intensive Care Unit of a public hospital in Istanbul between February and December 2025. The sample will include 60 preterm infants who meet the research criteria and whose parents agree to participate in the study.
Through randomization, preterm infants will be assigned to either the nasogastric tube group (experimental) or the orogastric tube group (control) from their first enteral feeding until the transition to full oral feeding is completed.
Data for preterm infants in both groups will be collected using the "Preterm Infant Information Form, Early Feeding Skills Assessment Tool, and Nutrition Monitoring Form," which were developed by the researchers based on literature information and expert opinions. These data will encompass growth, nutrition, and physiological parameters before, during, and after feeding throughout the study.
Hypotheses of the Study
H0: There is no significant difference in the effects of intermittent feeding methods using nasogastric and orogastric tubes on growth, feeding complications, and physiological parameters in preterm infants.
H1: There is a significant difference between intermittent feeding methods using nasogastric and orogastric tubes in preterm infants in terms of growth parameters (daily weight gain in grams, time to regain birth weight, time to transition to full enteral feeding, time to transition to full oral feeding, and Early Feeding Skills Assessment Tool score).
H1(1): Preterm infants fed with a nasogastric tube have greater daily weight gain (grams) compared to those fed with an orogastric tube.
H1(2): The time to regain birth weight (days) in preterm infants fed with a nasogastric tube is shorter compared to those fed with an orogastric tube.
H1(3): The time to transition to full enteral feeding (days) in preterm infants fed with a nasogastric tube is shorter compared to those fed with an orogastric tube.
H1(4): The time to transition to full oral feeding (days) in preterm infants fed with a nasogastric tube is shorter compared to those fed with an orogastric tube.
H1(5): The Early Feeding Skills Assessment Tool score of preterm infants fed with a nasogastric tube is higher compared to those fed with an orogastric tube.
H2: There is a significant difference between intermittent feeding methods using nasogastric and orogastric tubes in preterm infants in terms of feeding complications (tube replacement, mucosal trauma, and feeding intolerance).
H2(1): The frequency of tube replacement in preterm infants fed with a nasogastric tube is lower compared to those fed with an orogastric tube.
H2(2): The incidence of mucosal trauma in preterm infants fed with a nasogastric tube is lower compared to those fed with an orogastric tube.
H2(3): The incidence of feeding intolerance in preterm infants fed with a nasogastric tube is lower compared to those fed with an orogastric tube.
H3: There is a significant difference between intermittent feeding methods using nasogastric and orogastric tubes in preterm infants in terms of physiological parameters (oxygen saturation, heart rate, and apnea).
H3(1): The oxygen saturation levels during and after feeding in preterm infants fed with a nasogastric tube are higher compared to those fed with an orogastric tube.
H3(2): The heart rate during and after feeding in preterm infants fed with a nasogastric tube is lower compared to those fed with an orogastric tube.
H3(3): The incidence of apnea in preterm infants fed with a nasogastric tube is lower compared to those fed with an orogastric tube.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Since preterm infants breathe nasally, feeding with a nasogastric tube can cause partial nasal obstruction, leading to increased airway resistance and respiratory workload. This situation may result in the collapse of the pharyngeal airways and an increased incidence of apnea of prematurity in preterm infants. Additionally, prolonged feeding with a nasogastric tube in preterm infants has been reported to cause nasal septum defects. In contrast, while the placement and fixation of orogastric tubes are generally easier, these tubes can lead to complications such as displacement or incorrect placement into the lungs, aspiration, increased respiratory resistance, and bradycardia episodes due to vagal stimulation. Furthermore, the prolonged use of orogastric tubes in very low birth weight preterm infants may increase the risk of palate deformation. Therefore, the selection of the feeding method should be based on the infant's health status, respiratory functions, and other clinical parameters.
In the literature, studies investigating the effects of nasogastric and orogastric tubes on preterm infants have shown that the sample groups are limited, crossover designs were used, and there are methodological limitations regarding the determination of evaluation parameters and the process of transition to full enteral feeding. It has been observed that there is a need for a randomized controlled study with a large sample size to examine the effects of intermittent feeding methods using nasogastric and orogastric tubes on the growth, nutrition, and physiological parameters of preterm infants. Accordingly, this research was planned as a randomized controlled, prospective, double-blind study to compare the effects of intermittent feeding methods using nasogastric and orogastric tubes on the growth, nutrition, and physiological parameters of preterm infants.
The infants to be included in the study will be selected according to the determined inclusion criteria and then randomly divided into two groups: nasogastric tube feeding group and orogastric tube feeding group.
In the study, the randomization process will be carried out using the urn method. The urn method is equivalent to complete randomization and will be expressed with two parameters, α and β. These parameters will be symbolized as balls in red and white colors. White or red color will represent α; β will represent the opposite color of α. In each assignment process, the color of a randomly selected ball will determine which group the infant will be assigned to: when a white ball is selected, the infant will be assigned to the orogastric group, and when a red ball is selected, the infant will be assigned to the nazogastric group. In the study, the white ball will be designated as the orogastric group, and the red ball will be designated as the nazogastric group. For each new infant participant who meets the sample criteria, the previously prepared balls will be stored in a black bag, and a nurse on duty in the unit will randomly select one with their eyes closed. Based on the color of the selected ball, infants will be assigned to the groups, ensuring a random distribution between groups

Intermittent feeding method with nasogastric tube
Preterm infants in this group will be fed via a nasogastric tube during the transition period from the initiation of enteral feeding to full oral feeding.
Intermittent feeding method with nasogastric tube
30 Minutes Before Feeding: No invasive procedures will be performed 30 minutes before the daily 1:00 PM feeding.
5 Minutes Before Feeding: To measure physiological variables, the pulse oximeter probe will be attached to the baby's foot. Oxygen saturation and heart rate will be measured for 2 minutes before feeding.
Feeding Phase: Measurement values will be taken from the pulse oximeter during feeding.
Post-Feeding Phase: Any interventions that could affect physiological values will be prevented, and oxygen saturation and heart rate will continue to be measured during the 2-minute period. The baby will be scored using the Early Feeding Skills Assessment Tool.
