Fertility preservation measures given for preterm labor can help prolong the pregnancy, but cannot guarantee 100% success. Fertility preservation measures should be given as soon as possible when preterm labor occurs, proper rest should be paid attention to, glucocorticosteroids such as dexamethasone and betamethasone should be given if necessary to promote fetal lung maturation; contraction inhibiting treatments should be given depending on the situation, such as atosiban and magnesium sulfate, etc., and the condition of the pregnant woman and the fetus should be monitored during the use of these treatments; in the case of premature rupture of the fetal membranes, the infection should be controlled. The above measures can help prolong the pregnancy and improve the survival rate of the fetus. However, even if timely measures are taken to preserve the fetus, there may be progressive enhancement of contractions, which cannot be controlled after treatment and result in preterm labor. For those with intrauterine infections, those whose continued pregnancy is more harmful to the mother, and those ≥34 weeks of gestation, timely termination of pregnancy should be treated when necessary. After finding out that you are pregnant, you should consult a doctor as early as possible, build a perinatal health card, and have regular prenatal checkups to detect the risk factors for preterm labor as early as possible, and actively prevent preterm labor, which will help to greatly reduce the mortality rate of perinatal infants.
