Premature babies at 29 weeks do not need to pass the six hurdles, but they need some special care, because preterm babies are usually born at less than 37 weeks of gestation, their weight at birth is low, and other indicators are lower than those of full-term babies. The body’s ability to adjust to the external environment is poor. Therefore, usually 29 weeks after the delivery of preterm infants have to enter the incubator to treat, give some special treatment such as promoting fetal lung maturation, preterm infants in the incubator period should always be observed, until the baby indicators are more stable before you can consider leaving the incubator.
