The neonate intensive care unit (NICU) is a high-stress environment can affect the hormone secretion, cardiopulmonary function, sleep/wake cycle, alertness, temperature regulation, and intellectual development of premature infants. It is not conducive to their recovery, growth, and development. The sound of the mother's heartbeat and white noise can stabilize the heart rate and respiration of premature infants and alleviate pain. This study aims to analyze the effects of the sound of the mother's heartbeat combined with white noise on the heart rate, weight, and sleep status of premature infants in the NICU.
We retrospectively analyzed 121 premature infants admitted to the Newborn Department of Suzhou Kowloon Hospital from January 2019 to December 2021. The infants were divided into an intervention group (those given the mother's heartbeat sound combined with white noise) and a control group (routine treatment and nursing); the heart rate, sleep state, weight and weight gain rate of the two groups were compared before and after the intervention.
The heart rate and behavioral status scores of the intervention group during the intervention (10, 20 min) and 1 min after the intervention were significantly lower than 1 min before the intervention (P<0.05). The intervention group's weight was significantly higher than the control group's on the 14th day after intervention (P<0.05), and the rate of weight gain was faster than that of the control group (P<0.05). The average daily milk intake of the intervention group in the first and second weeks was higher than that in the control group (P<0.05). Multiple stepwise regression analysis showed that the rate of weight gain in the intervention group was higher than that in the control group (P<0.05).
The combination of the auditory stimulation of the mother's heartbeat and white noise for premature infants in NICU can effectively reduce the heart rate of premature infants, stabilize their mood, promote their sleep, increase the amount of milk consumption during hospitalization, increase the rate of weight gain, and promote their physical development.
新生儿重症监护病房（NICU）是一个高压力环境，会影响早产儿的激素分泌、心肺功能、睡眠/觉醒周期、警觉性、体温调节和智力发育。这不利于他们的康复、生长和发育。母亲的心跳声和白噪音可以稳定早产儿的心率和呼吸，并减轻疼痛。本研究旨在分析母亲心跳声与白噪音相结合对NICU中早产儿心率、体重和睡眠状态的影响。
我们回顾性分析了2019年1月至2021年12月在苏州九龙医院新生儿科收治的121例早产儿。将婴儿分为干预组（给予母亲心跳声与白噪音）和对照组（常规治疗和护理）；比较两组干预前后的心率、睡眠状态、体重和体重增加率。
干预组在干预期间（10、20分钟）及干预后1分钟的心率和行为状态评分显著低于干预前1分钟（P<0.05）。干预组在干预后第14天的体重显著高于对照组（P<0.05），体重增加率比对照组快（P<0.05）。干预组第一周和第二周的平均每日奶量高于对照组（P<0.05）。多元逐步回归分析显示，干预组的体重增加率高于对照组（P<0.05）。
NICU中对早产儿采用母亲心跳声与白噪音的听觉刺激相结合，可有效降低早产儿心率，稳定其情绪，促进其睡眠，增加住院期间的奶量摄入，提高体重增加率，促进其身体发育。
