In neonatal intensive care unit (NICU), neonatal sleep is disrupted due to different factors. Due to the critical role of sleep in premature infants' brain development, this study aimed to investigate the effect of nesting and swaddling on the sleep duration of premature infants hospitalized in NICUs.
In a crossover clinical trial, 42 preterm infants who met the inclusion criteria were enrolled. They were randomly assigned to two groups of nest-swaddle and swaddle-nest. Sleep status was evaluated by observation and use of Prechtl's criteria. Then, durations of total sleep time (TST) and quiet sleep time (QST) were recorded. Data were analyzed using repeated measure analysis of variance (ANOVA).
Mean values of TST and QST during nesting and also swaddling periods were significantly higher than in the control period in both groups ( < 0.001). Mean values of TST and QST in the swaddling period were higher than in the nesting period in both groups, However, these differences were not significant ( = 0.245).
Both swaddling and nesting could significantly increase the duration of TST and QST, compared to the control. There were no significant differences between the effects of these interventions on TST and QST. Therefore, using any of these methods is suggested to improve infants' quality of sleep in NICU, with respect to the ward policies.
在新生儿重症监护病房（NICU），新生儿睡眠会因不同因素而受到干扰。由于睡眠对早产儿大脑发育至关重要，本研究旨在探讨鸟巢式护理和襁褓包裹对入住NICU的早产儿睡眠时间的影响。
在一项交叉临床试验中，纳入了42名符合纳入标准的早产儿。他们被随机分为鸟巢式护理-襁褓包裹组和襁褓包裹-鸟巢式护理组。通过观察和使用Prechtl标准评估睡眠状态。然后，记录总睡眠时间（TST）和安静睡眠时间（QST）。使用重复测量方差分析（ANOVA）对数据进行分析。
两组在鸟巢式护理期间和襁褓包裹期间的TST和QST平均值均显著高于对照组（<0.001）。两组在襁褓包裹期间的TST和QST平均值均高于鸟巢式护理期间，然而，这些差异不显著（=0.245）。
与对照组相比，襁褓包裹和鸟巢式护理均可显著增加TST和QST的时长。这些干预措施对TST和QST的影响之间无显著差异。因此，建议根据病房政策采用这些方法中的任何一种来改善NICU中婴儿的睡眠质量。
