37 weeks of gestation is considered full term and a newborn weighing more than 5 pounds is not considered preterm. If the mother has gestational diabetes or hypertension, she may be sent to the neonatal unit for observation. The prognosis is not certain and the cost is generally high. The lungs are usually mature around 34 weeks of gestation, and once the contractions are unavoidable, those who are considering a short period of delivery can be given intramuscular dexamethasone to help promote lung maturation, while the compression of the birth canal during vaginal delivery is also beneficial to lung maturation, and if there are no other comorbidities, the newborn is in good health. Delivery at 37-41 weeks of gestation is a normal time for delivery, and it is not recommended to wait until more than 42 weeks to deliver because the placenta is already severely deteriorated at this time, which may lead to fetal ischemia and hypoxia in the uterine cavity, which is detrimental to fetal survival. In late pregnancy, it is important to pay attention to symptoms such as abnormal vaginal fluid flow, frequent hardening of the stomach and bloody vaginal discharge to avoid preterm labor. The 37th week of pregnancy is not considered preterm birth, and breastfeeding is recommended after delivery, which can strengthen the baby’s resistance and is also beneficial to the recovery of the uterus.
