| Summary: | 碩士 === 輔仁大學 === 護理學系碩士班 === 104 === This study was aimed to compare semi- prone and supine position on physiological indicators (breathing, heart rate, and blood oxygen) and behavioral states in preterm infants. Thirty preterm infants without congenital symptoms of major diseases were recruited from a medical center in northern Taiwan. Study was designed using cross over experimental design that was conducted on the basis of repeated measurements of time-series, the preterm infants were randomly assigned to semi-prone (experimental group) or supine (control group), adopted one of these positions (semi-prone or supine), measuring their physiological indicators and behavioral state. In the following day (during the washout period), the posture was changed to another position to record on the measurements of repeated observations. The results showed that: preterm infants’ breathing rate, heart rate and oxygen saturation tend to be more stable with semi- prone position when compared to supine position. Preterm infants with semi-prone had significant differences of behavioral state between sleep states (1, 2) than the supine position (53.6% vs. 26.7%；p < 0.05). The results of this study can be used as a school or hospital in-service education curriculum and as a reference for clinical practice, which provides information about the positioning of premature infants.
