To assess the effects of exposure to the odour of mother's milk on breastfeeding behaviour of premature neonates.
Thirteen preterm infants born at 30-33 weeks gestational age were tested. Seven infants were randomly assigned to the milk-odour condition, 6 to the water-control condition. During week 35 post-conceptual age, each baby was exposed to the appropriate odour stimulus for 120 sec. on 5 consecutive days immediately prior to a breastfeeding attempt. The breastfeeding bout following the final odour exposure session, and a second breastfeeding session shortly before the baby left the hospital, were analysed. Babies were weighed before and after each feeding session.
During each breastfeeding session, babies in the milk-odour condition displayed longer sucking bouts and more bursts composed of >7 sucking movements, and also consumed more milk than the Control infants. The time spent in the hospital was significantly less for the milk-odour condition (median = 43 days vs. 55.5 days for Controls).
Brief exposure to the odour of mother's milk prior to early breastfeeding trials had a positive effect on sucking behaviour and milk ingestion of preterm babies, which in turn resulted in a shortened stay in the hospital.
评估接触母乳气味对早产新生儿母乳喂养行为的影响。
对13名孕龄为30 - 33周的早产儿进行测试。7名婴儿被随机分配到母乳气味组，6名婴儿被分配到水对照组。在孕龄35周时，每个婴儿在每次尝试母乳喂养前连续5天每天接触适当的气味刺激120秒。分析最后一次气味暴露后的母乳喂养过程，以及婴儿出院前不久的第二次母乳喂养过程。每次喂养前后对婴儿进行称重。
在每次母乳喂养过程中，母乳气味组的婴儿吸吮时间更长，由超过7次吸吮动作组成的吸吮阵次更多，并且比对照组婴儿摄入的母乳更多。母乳气味组婴儿的住院时间明显更短（中位数 = 43天，而对照组为55.5天）。
在早期母乳喂养试验前短暂接触母乳气味对早产婴儿的吸吮行为和母乳摄入有积极影响，进而缩短了住院时间。
