Variation de la mortalité périnatale selon l'heure de naissance en Suisse. [Variations in perinatal mortality according to the hour of birth in Switzerland].

In Switzerland like in most developed countries, the number of births is strongly related to the hour of the day and the day of the week: this pattern is very probably related to the current practice in obstetrics. Less expected is the fact that the perinatal mortality shows a striking circadian rhythm according to the hour of birth. The paper presents this pattern and comments some related issues.

Influence d'une hospitalisation prénatale sur les facteurs de stress parentaux lors d'une naissance prématurée [Influence of prenatal hospitalization on parental stressful experience in the case of a premature birth].

OBJECTIVES: To investigate the influence of prenatal hospitalization before a premature birth, on the parental stressful experience, parental symptoms of post-traumatic stress and quality of parent-infant interaction during the hospitalization in neonatology. POPULATION AND METHODS: Population: 51 preterm infants born and 25 full term infants control. Four groups: controls, premature without prenatal hospitalization, premature with a short (<8 days) prenatal hospitalization and premature with a long (≥8 days) prenatal hospitalization. Instruments: the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS: NICU, Miles et al., 1993 [14]) and the Perinatal PTSD Questionnaire (PPQ, Quinnell and Hynan, 1999 [16]). RESULTS: When prenatal hospitalization of the mother occurred, parents acknowledged increased stress induced by the environmental factors during the infant's hospitalization. Furthermore, mothers from the group with a short prenatal hospitalization presented significantly more symptoms of post-traumatic stress. Parents presenting more symptoms of post-traumatic stress describe a significantly more difficult interaction with their infant in neonatology. CONCLUSION: This study highlights the necessity to deliver special care to women hospitalized shortly (<8 days) prior to the delivery of their premature baby. This group is at high risk of presenting post-traumatic stress symptoms, which could have a negative impact on the quality of parent-infant interactions.
