Abstract

Abstract:

Objective To analyze the clinical characteristics of extremely premature infants conceived by assisted reproductive technology (ART). Methods The clinical data of extremely premature infants admitted to the neonatal intensive care unit from January 2016 to December 2022 were collected. The patients were divided into the ART group and the natural conception (NC) group, and the clinical features between the two groups were compared. Results A total of 478 extremely premature infants were admitted during the study period, including 279 in the NC group and 199 in the ART group. Compared with the NC group, the ART group had lower proportions of male infants and premature rupture of membranes lasting more than 18 hours, but higher proportions of double/multiple births, maternal amniotic fluid abnormalities, gestational diabetes mellitus, periventricular-intraventricular hemorrhage (PIVH), abandonment and death, and the differences were statistically significant (P<0.05). Conclusions The incidence of PIVH in extremely premature infants conceived by ART is higher, and their parents are easy to give up treatment, and the case fatality rate of patients is higher. It is necessary to strengthen the maternal health care during the ART pregnancy and reduce the complications, in order to prevent the occurrence of extremely premature births.
