Nowadays, with the improvement of medical technology, the survival rate of preterm babies is getting higher and higher. 30 weeks preterm babies are late preterm babies, and if they are less than 28 weeks, they are early preterm babies. Nowadays, medical technology is getting better and better, and most of 30-week preterm babies can survive. However, if the postnatal score is very poor and the resuscitation process is not successful, neonatal death may occur. Even if the score is fair after birth, complications of prematurity such as neonatal respiratory distress syndrome may occur. Currently, pulmonary surface active substances, as well as ventilators, can be used to help with breathing. With increasing time, preterm infants may also develop feeding intolerance, and intravenous nutrition can now also be used to help with the child’s nutritional supply. So a preterm baby born at 30 weeks is generally survivable.
