Background: 

Family-integrated care in the neonatal intensive care unit (NICU) is the criterion standard. Parent–infant bonding may be an indicator of successful family involvement. Music therapy (MT) is a growing service in the NICU, with interventions to support meaningful family involvement and improve bonding.

Purpose: 

To study the effects of heartbeat-music interventions to support mother–infant bonding in the NICU and explore experiences of mothers participating in MT.

Methods: 

Parallel-group randomized trial (MT vs standard care) to compare Mother-to-Infant Bonding Scale (MIBS) scores from baseline to 1 week postenrollment. MT included 2 heartbeat-music interventions (recorded maternal lullaby and heartbeat for infants, and recorded infant heartbeat and preferred music for mothers). Five mothers were randomly asked to complete a survey regarding their experiences with MT services.

Results: 

One hundred mothers enrolled. In total, 44.3% completed the MIBS follow-up. Covarying out baseline MIBS, one-way analysis of covariance found no statistical difference between groups for MIBS 1-week follow-up (MT: mean = 0.64, SD = 1.6; standard care: mean = 0.57, SD = 1.5; P = .60) but underpowered in post hoc. Comforting, family cohesion, and personal growth and development themes emerged in qualitative analysis of survey responses.

Implications for Practice: 

MT remains a viable service for purposefully including parents in the care of their NICU infants. Nurses and music therapists must work closely to successfully implement meaningful interventions such as heartbeat-music.

Implications for Research: 

Heartbeat-music interventions should be further studied for diverse applications, including family integration, family coping, and bereavement.

NICU 中的音乐疗法和家庭综合护理：使用心跳音乐干预促进母婴关系

背景： 

新生儿重症监护病房 ( NICU ) 的家庭综合护理是标准。亲子关系可能是家庭参与成功的一个指标。音乐疗法 (MT) 是NICU中一项不断发展的服务，其干预措施可支持有意义的家庭参与并改善关系。

目的： 

研究心跳音乐干预对支持NICU中母婴关系的影响，并探索母亲参与 MT 的经验。

方法： 

平行组随机试验（MT 与标准护理）比较从基线到入学后 1 周的母婴关系量表 (MIBS) 分数。MT 包括 2 种心跳音乐干预（为婴儿录制母亲摇篮曲和心跳，为母亲录制婴儿心跳和首选音乐）。五位母亲被随机要求完成一项关于她们使用 MT 服务的经历的调查。

结果： 

一百位母亲报名参加。总共有 44.3% 的人完成了 MIBS 随访。协方差基线 MIBS，协方差的单向分析发现 MIBS 1 周随访组之间没有统计学差异（MT：平均值 = 0.64，SD = 1.6；标准治疗：平均值 = 0.57，SD = 1.5；P = . 60) 但在事后分析中动力不足。安慰、家庭凝聚力以及个人成长和发展主题出现在调查响应的定性分析中。

实践意义： 

MT 仍然是一项可行的服务，有目的地让父母参与其NICU婴儿的护理。护士和音乐治疗师必须密切合作才能成功实施有意义的干预措施，例如心跳音乐。

研究意义： 

应进一步研究心跳音乐干预的不同应用，包括家庭融合、家庭应对和丧亲之痛。
