The supine sleeping position in the prevention of sudden infant death syndrome in preterm infants is poorly understood. We aimed to investigate the effect of sleep posture on cardiorespiratory parameters and movement patterns in preterm infants close to discharge.
This observational study included neonates born in 2022 at the University Hospital Schleswig-Holstein, Lübeck, Germany. Motion sensor data, heart rate, respiratory rate and oxygen saturation were recorded for infants with postconceptional age 35-37 weeks during sleep in the prone and supine positions.
We recorded data from 50 infants, born at 31 (24-35) weeks of gestation (mean(range)), aged 5.2 ± 3.7 weeks (mean ± SD), of whom 48% were female. Five typical movement patterns were identified. In the prone position, the percentage of calm, regular breathing was higher and active movement was less frequent when compared to the supine position. The percentage of calm irregular breathing, number of apnoeas, bradycardias, desaturations and vital sign changes were not influenced by position.
The prone position seems to be associated with a higher arousal threshold. The supine position appears advantageous for escape from life-threatening situations such as sudden infant death syndrome.
早产儿中预防婴儿猝死综合征的仰卧睡眠体位尚未被充分理解。我们旨在研究接近出院时的早产儿睡眠体位对心肺参数和运动模式的影响。
这是一项观察性研究，纳入了 2022 年在德国石勒苏益格-荷尔斯泰因州吕贝克大学医院出生的新生儿。对孕龄 35-37 周的婴儿，在仰卧和俯卧两种睡眠体位下，记录运动传感器数据、心率、呼吸频率和氧饱和度。
我们记录了 50 名婴儿的数据，这些婴儿的胎龄为 31（24-35）周（平均值（范围）），年龄为 5.2±3.7 周（平均值±标准差），其中 48%为女性。确定了 5 种典型的运动模式。与仰卧位相比，俯卧位时安静、规则呼吸的比例更高，而主动运动的频率更低。俯卧位时，安静不规则呼吸、无呼吸暂停、心动过缓、低氧血症和生命体征变化的比例不受体位影响。
俯卧位似乎与更高的觉醒阈值相关。仰卧位对于避免婴儿猝死综合征等危及生命的情况似乎更有利。
