The purpose of this study was to assess gastrointestinal responses to formula temperature in preterm infants. Healthy preterm infants were fed 4,250 KJ/l formula at 6, 24, and 37 degrees C. There was no significant difference in the magnitude of antral or duodenal motor responses among the three temperatures. All infants emptied approximately one third of the bolus feeding by 20 min, but there was no difference among the temperatures. Approximately 10-20% of a bolus feeding remained in the stomach 2 h postprandially, but there was no difference among the temperatures. Thermoreceptors do not appear to be functionally present in the preterm infant, suggesting that the benefit of feeding warmed formula to the preterm infant my have a limited physiological value.
本研究的目的是评估早产儿对配方奶温度的胃肠道反应。健康的早产儿分别喂食6℃、24℃和37℃的4250千焦/升配方奶。三种温度下胃窦或十二指肠运动反应的幅度没有显著差异。所有婴儿在20分钟内排空了大约三分之一的推注式喂养奶量，但不同温度之间没有差异。餐后2小时，大约10%-20%的推注式喂养奶量仍留在胃中，但不同温度之间没有差异。热感受器在早产儿中似乎没有功能，这表明给早产儿喂食温热配方奶的益处可能生理价值有限。
