简要总结
The purpose of this study is to determine the effect of Semielevated Side-Lying (ESL) and Semielevated Supine Position (ESU) positions used in bottle-feeding of very preterm infants upon their physiological characteristics and feeding performances.
详细描述
Semielevated supine position (ESU) is a position frequently used in neonatal intensive care units. In this position, infant is laid and fed on its back and the head is elevated to an angle of 45-60° in order to reduce the respiratory load of lungs. The ESL position, head of the infant is elevated to an angle of 45-60° and the infant is fed in the side-lying position. Since this position mimics the breast-feeding position, very preterm infants are supported to utilize the advantages of breast-feeding. A randomization was provided in the sample group consisting of totally 80 infants and while 38 infants were included in the ESL (experimental) group, 42 infants were included in the ESU (control) group.In the power analysis repeated at the end of the study, the power of the study was determined as 87% at a reliability of 95%.

研究组 & 干预措施
Semielevated Side-Lying Position-ESL
Preterm infants feed in the ESL position. In the ESL position, infant's head and trunk were elevated to an angle of 45-60° with the help of a pillow prepared by the researcher from the beds that were previously used in the unit and infants were held in side-lying position as in the breast-feeding position where their right ear faced the ceiling and the other ear faced the arms of the researcher. Their knees and hip were leaned against the researcher's arms and both the head and the neck were held at the same level by the researcher, whereas the chin was held in the flexion posture mildly facing the floor.
干预措施: Semielevated Side-lying Position-ESL (Other)
Semielevated Supine Position-ESU
Before feeding: In the ESU position, the head and the trunk of the infant were elevated to an angle of 45-60° with the help of the same pillow that was prepared by the researcher from the beds previously used in the unit and was used in the experimental group and the infant was laid in supine position in the arms of the researcher. Their head and neck were held at the same level by the researcher, whereas the chin was held in the flexion posture mildly facing the floor.
干预措施: Semielevated Supine Position (Other)
结局指标
主要结局
Percentage of Oxygen Saturation
时间窗: During feeding (maximum 30 min)
Oxygen saturation were measured by using a pulse oximeter 2 min before the feeding, during the feeding and for 30 min after the feeding.
次要结局
- Heart Rate/Minute During Feeding(During feeding (maximum 30 min))
