Discomfort, pain, and stress have an adverse impact on the psychomotor development in the premature newborn infant. Recent studies indicate that pain and stress are associated with a reduction of parasympathetic outflow. We hypothesized that cocooning associated with the human voice has a favorable impact on parasympathetic activity in the premature newborn infant.
We compared heart rate variability (HRV) before and after standardized cocooning phases associated with the human voice and carried out: 1) by the mother and 2) by a third person. HRV was assessed and expressed as an index reflecting the parasympathetic tone.
Ten children were included (median gestational age, 33 weeks (30(+4)-33(+2))). We observed a higher HRV index after the period of cocooning associated with the human voice compared with the baseline measurement (P<0.05), whether the procedure was carried out by the mother or a third person.
This study shows that cocooning associated with the human voice enhances HRV in the preterm newborn infant, indicating an increase in parasympathetic activity after cocooning associated with the human voice. However, the impact is similar whether the cocooning associated with the human voice is performed by the mother or a third person. This result suggests that cocooning associated with the human voice carried out either by the mother or a third person contributes to decreasing stress and discomfort in the premature newborn infant.
不适、疼痛和压力会对早产新生儿的心理运动发育产生不利影响。最近的研究表明，疼痛和压力与副交感神经输出减少有关。我们假设与人类声音相关的包裹护理对早产新生儿的副交感神经活动有积极影响。
我们比较了与人类声音相关的标准化包裹护理阶段前后的心率变异性（HRV），并进行了：1）由母亲进行；2）由第三方进行。HRV被评估并表示为反映副交感神经张力的指标。
纳入了10名儿童（中位胎龄33周（30（+4）-33（+2）））。我们观察到，与基线测量相比，在与人类声音相关的包裹护理期后，HRV指数更高（P<0.05），无论该操作是由母亲还是第三方进行。
本研究表明，与人类声音相关的包裹护理可提高早产新生儿的HRV，表明与人类声音相关的包裹护理后副交感神经活动增加。然而，无论与人类声音相关的包裹护理是由母亲还是第三方进行，其影响都是相似的。这一结果表明，由母亲或第三方进行的与人类声音相关的包裹护理有助于减轻早产新生儿的压力和不适。
