Objectives:
To study the treatment outcomes of extremely preterm infants.
Methods:
A retrospective analysis was performed for the clinical data of extremely preterm infants who were admitted to the neonatal intensive care unit of the Third Affiliated Hospital of Zhengzhou University from January 2016 to December 2022. The infants were divided into a non-in-hospital death group and a survival group. SPSS 29.0 was used for data analysis.
Results:
A total of 422 extremely preterm infants were included, of which 155 were in the non-in-hospital death group and 267 in the survival group. The gestational age, birth weight, cesarean section rate, and proportion of mothers with premature rupture of membranes >18 hours in the non-in-hospital death group were all lower than those in the survival group (P<0.05). In contrast, the proportions of Apgar score ≤3 at 1 minute, intubation, neonatal respiratory distress syndrome, early-onset sepsis, periventricular-intraventricular hemorrhage (grades III-IV), and pneumorrhagia were higher in the non-in-hospital death group compared to the survival group (P<0.05).
Conclusions:
Low gestational age, low birth weight, the history of birth asphyxia, severe intracranial hemorrhage, and pneumorrhagia may be the main causes of non-in-hospital death in extremely preterm infants, and therefore, perinatal health care should be enhanced to reduce the onset of asphyxia and severe diseases.
