Preterm infants are relatively mature at 32 weeks and have a survival rate of about 70%. Preterm birth refers to deliveries at 28 weeks of gestation but less than 37 weeks (196-258 days of intrauterine gestation), and newborns delivered during this period are clinically referred to as preterm. Premature infants weigh less than 2500g because their organs are not sufficiently developed, and the smaller the week of gestation and the lighter the weight, the worse the prognosis. About 15% of preterm infants die in the neonatal period, and about 2/3 of infants who die within 1 year of birth are preterm. Another 8% of preterm infants survive, but are left with mental retardation or neurological sequelae. The survival rate of preterm infants varies specifically in individual or overall rates, but in general, the overall survival rate is up to 70% at 32 weeks when the fetus is relatively mature. Therefore, preterm birth should start from prevention, first of all, we should strengthen pregnancy examination, pay attention to pregnancy hygiene, and pay full attention to the triggering factors that may cause preterm birth, and correct them early. If there are signs of preterm labor, you should keep quiet and try to take fetal preservation measures. Complications during pregnancy should be treated differently for different conditions. In general, a 32-week preterm baby will grow healthily as long as he is fed and cared for reasonably after birth to ensure steady weight gain. Although the survival rate of preterm babies is low, but 32 weeks preterm babies can grow up healthily with reasonable feeding.
