Abstract:
With advancements in perinatal and neonatal medicine, neonatal mortality rates have significantly decreased, particularly among full-term infants. However, the proportion of preterm infant deaths within neonatal mortality has markedly increased, making preterm infant mortality a critical concern. Due to the wide range of gestational ages among preterm infants, there are significant differences in mortality rates and causes of death depending on gestational age. It is crucial for perinatal medical professionals to recognize the varying mortality rates of preterm infants of gestational ages. In recent years, the mortality rate of late preterm infants in developed countries has been below 2%, with the mortality rate of very preterm infants varying from 1% to 6% depending on their gestational age, while the survival rate of extremely preterm infants of different gestational ages ranges from 60% to 95%. Compared to developed countries, China has achieved a similar mortality rate for late preterm infants, and the mortality rate for very preterm infants is gradually approaching that of developed countries. Nevertheless, there remains a significant gap in the survival rate of extremely preterm infants. This article reviews the characteristics and trends in the survival of preterm infants of different gestational ages both domestically and internationally, aiming to enhance the attention to preterm infant outcomes.
