Immediately after birth, preterm newborns are immersed in a hostile environment of intensive care unit with light, sound and painful stimulations. Previously, exposure to maternal voice has demonstrated improvement on infants' statements: reduction of bradycardia, desaturation events, improvement of tolerance feeding and sleep. Unfortunatly in most of the N ICU in France, the mothers' presence attendance time is reduced because of the absence of accommodation structure. The use of a specific neonatal device able to daily record maternal voice and hearbeats and to restore it when mother is gone could improve the environment and promote the well-being of the newborn.
The purpose of this study is to evaluate the benefits of an exposition to a maternal voice and heartbeat recording during hospital stay for preterm newborns. For that, we use of a specific neonatal device Calinange able to record maternal voice and heartbeats and to restore it with a sound level control. We hypothesize an improvement of the well being of the newborn under Calinange exposition.
