The complication rate and death rate of preterm infants with gestational weeks ≥34 weeks, birth weight ≥2 000 g were significantly lower than those of the preterm infants with gestational weeks 〈 34 weeks, birth weight 〈 2 000 g （P 〈 0.05） . Conclusions Appropriate choice of controlled premature delivery can be beneficial to lower the mortality of pregnant women and in - crease the survival rate of perinatal infants.
