The average gestational age of the infants was 39 ± 1.41 weeks, with one neonate delivered preterm at 36 weeks without complications. Sixteen of the 54 infants were born by cesarean delivery. Normal Apgar scores at delivery were recorded, with only one neonate with blue asphyxia and an Apgar score of 7; the blue asphyxia symptoms disappeared after aggressive treatment, and the subsequent 5- and 10-min Apgar scores were normal.
The most common adverse events for infants were nuchal cord (13/54, 24.07%) and premature rupture of the membranes (4/54, 7.41%). Other adverse events included extremely long umbilical cord and caput succedaneum. There were no fetal developmental abnormalities reported around the time of delivery.
