title: [Clinical analysis of 242 cases of controlled preterm delivery].
abstract: OBJECTIVE
  To understand the effect of controlled premature delivery and its termination method of pregnancy.
  
  
  METHODS
  The clinical data of 242 cases of controlled premature delivery were retrospectively analyzed.
  
  
  RESULTS
  The incidence of premature delivery was 5.75% and the incidence of controlled premature delivery was 46.81%. Pregnancy induced hypertension (PIH) was the first-place reason of controlled premature delivery. The cesarean section rate of controlled premature delivery was 64.88%, which was significantly higher than that of natural premature delivery (16.45%, P < 0.05); the rate of postpartum hemorrhage and neonatal suffocation in controlled premature delivery was significantly lower than that of natural premature delivery (P < 0.05).
  
  
  CONCLUSIONS
  Appropriately controlled premature delivery can be beneficial to the newborn's survival rate and can lower the mortality of pregnant women.
