The aim of the current study was to developed and test the reliability of a technique for measuring temporal parameters of sucking in breastfeeding infants.
The technique was developed using a cohort of 11 term and 12 preterm infants, and subsequently evaluated using a cohort of 43 preterm infants. Measurements related to sucking pressure in the term and preterm infants were acquired. The signals were recorded for 5 min, saved on a computer, and stored for analysis. For purposes of analysis, the minute with the highest quality signal was chosen. Signal analysis was performed by two researchers, and inter- and intra-observer agreement was assessed. The newborns in the sample had different gestational ages.
A technique was developed for the analysis of temporal parameters of sucking during breastfeeding and evaluated in 43 preterm infants with different gestational ages for the following variables: number of bursts per minute, number of sucks per burst, sucking rate, pause rate, and duration of pauses. The intra-observer agreement was 0.85 and the inter-observer agreement was 0.85.
The technique that was developed and validated proved capable of measuring temporal parameters of sucking in breastfeeding newborns.
本研究旨在开发和测试一种测量母乳喂养婴儿吸吮时时间参数的技术的可靠性。
该技术是使用 11 名足月和 12 名早产儿队列开发的,随后使用 43 名早产儿队列进行评估。对足月和早产儿的吸吮压力相关测量值进行了采集。信号记录持续 5 分钟,保存到计算机上,并存储进行分析。为了分析,选择了信号质量最高的分钟。由两位研究人员进行信号分析,并评估了观察者内和观察者间的一致性。样本中的新生儿具有不同的胎龄。
开发了一种用于分析母乳喂养时吸吮时间参数的技术,并在 43 名不同胎龄的早产儿中进行了评估,用于评估以下变量:每分钟爆发次数、每次爆发的吸吮次数、吸吮频率、停顿频率和停顿持续时间。观察者内一致性为 0.85,观察者间一致性为 0.85。
所开发和验证的技术能够测量母乳喂养新生儿吸吮的时间参数。
