Perinatale Mortalität
摘要
Perinatal mortality refers to stillbirths in the second half of pregnancy and early neonatal deaths within the first 7 days of life. These fatalities exceed the rate of deaths between 8 days and 18 years of life. Rates of stillbirths (4.3 per 1000 live births) have not declined over the past 20 years in Germany, in contrast to infant mortality (3.3 per 1000). More than 22% of stillbirths occur after 37 weeks of gestation, often without any recognized risk factors. Perinatal mortality may be reduced by planned birth at 39–40 weeks of gestation. Sudden unexpected postnatal collapse occurring within the first 7 days of life has been reported as a specific form of sudden infant death, usually within the first few hours. It is associated with prone positioning and maternal exhaustion. Continuous pulse oximetry monitoring has been implemented in several hospitals as a simple, noninvasive approach to reduce early neonatal deaths of healthy term infants in the delivery room.
