When preterm labor is detected, if the fetal membranes are intact and the mother and fetus are in good condition, try to keep the fetus until 34 weeks and monitor the mother and child at the same time. If the contractions are frequent but there is no change in the cervix, magnesium sulfate or nifedipine can be used to suppress the contractions. The pregnant woman should rest properly, reduce activities, avoid standing for a long time, and review the ultrasound regularly to observe the condition of the fetus. If there are changes in the cervix of a pregnant woman with preterm labor, it is recommended that she be immediately hospitalized and strictly rest in bed. If there is severe vaginal bleeding, it can be treated by infusion of hemostatic drugs while suppressing contractions. Pregnant women with preterm labor need to be hospitalized immediately when they show symptoms of preterm labor. When the pregnancy is less than 35 weeks but delivery is possible within 1 week, glucocorticoids should be used to promote fetal lung maturation, and contraction inhibitors should be used at the same time. Although contraction inhibitors do not prevent preterm delivery, they may prolong the pregnancy by 3-7 days, buying time for fetal lung maturation. Usually after the fetal lung matures, the fetus can enter labor and delivery, and the newborn needs to go into the incubator for observation for about 2 weeks after birth.
