Brief summary

The main purpose of this study is to identify and to determine the involvement of cardio-respiratory coordination mechanisms during SSC between the preterm infant and his (her) parent.

Detailed description

The skin to skin care (SSC) is a technique that proceeds by laying the neonate ventrally on the parent's chest. Many positive effects are recognized as due to SSC i.e, maintaining the infant's body temperature, better sleep organization, neurocognitive development and cardio-respiratory stability, more strength in parent-infant affective relations, reduction in neonatal and parental stress, more success in feeding with breast milk. Nowadays, SSC is generalized in modern Neonatal Intensive Care Units as part of developmental care. However, the mechanisms involved in SSC are not totally understood. The hypothesis in this study is that the cardio-respiratory stability results partially from the intervention of the coordination between cardiac and respiratory activities. These suppose the involvement of complex mechanisms of cardio-respiratory coordination including neuro-autonomous loops with chemoreceptors and baroreceptors, bulbar vasomotor and respiratory regulatory centers, ortho-parasympathetic neuronal and chemical pathways and cardiac, vascular and lung effectors. In this study the identification of these characteristics will be performed by processing signals of ECG, SaO2 (arterial oxygen saturation), respiratory movements, perfusion index, cutaneous and ambient temperature extracted from the clinical monitoring systems. Each preterm infant included in the study will be explored twice, 5-10 days apart. The explorations will be carried out on 3 steps: before (at least 30 minutes), during (at least 60 minutes) and after (≥ 60 minutes) the SSC session. Each patient will participate in the study for 10 days at maximum. Inclusions in the study will last for a total period of 18 months and 10 days. The cardio-respiratory coordination will be assessed using coordigram technique, corresponding to the proportion of time with \> 0.7 amplitude on spectral density.
