Birth at 36 weeks gestation is considered preterm, and any birth before 28~37 weeks gestation is considered preterm. A woman who is pregnant and delivers at 28~37 weeks of gestation is considered preterm, and 36 weeks is within the range of preterm birth, and the birth is a preterm baby. Preterm babies born at 36 weeks of gestation are nearly full-term, and the development of all organs tends to be mature, and brain development is very similar to that of full-term babies, which is less likely to produce brain diseases. Preterm babies born at this stage are more likely to survive, but their resistance and immunity are relatively low, and changes in vital signs should be closely monitored after birth. Most 36-week preterm babies will have no significant health problems or defects, and a small percentage may have defects such as neonatal asphyxia, brain damage, and infections. Severe problems such as cerebral palsy and hearing impairment may occur. Preterm babies born at 36 weeks should be carefully cared for and medical attention should be sought for any abnormalities.
