OBJECTIVES@#To study the
survival rate and the
incidence of
complications of very
preterm infants and the factors influencing the
survival rate and the
incidence of
complications.@*
METHODS@#The medical data of the very
preterm infants with a
gestational age of <32 weeks and
who were admitted to the Department of
Neonatology in 11
hospitals of Jiangsu Province in
China from January 2018 to December 2019 were retrospectively reviewed. Their
survival rate and the
incidence of serious
complications were analyzed. A multivariate
logistic regression analysis was used to evaluate the
risk factors for
death and serious
complications in very
preterm infants.@*RESULTS@#A total of 2 339 very
preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious
complications. The groups with a
gestational age of 22-25@*CONCLUSIONS@#The
survival rate is closely associated with
gestational age in very
preterm infants. A low 1-minute
Apgar score (≤3) may increase the
risk of
death in very
preterm infants, while high
gestational age, high
birth weight, and prenatal use of
glucocorticoids are associated with the reduced
risk of
death. A low 5-minute
Apgar score (≤3) and maternal
chorioamnionitis may increase the
risk of serious
complications in these
infants, while high
gestational age and high
birth weight may reduce the
risk of serious
complications.
