The survival rate of six-month preterm babies is low. Six-month-old fetuses have a lower survival rate after preterm delivery due to the immaturity of all organs, especially the fetal lungs, which are not yet mature and the respiratory system is weak and unable to adapt to the external environment. Six-month-old fetuses need to be sent to the neonatal intensive care unit for observation and ventilator-assisted respiration to promote the maturation of the fetal lungs, and preterm infants are prone to intracranial hemorrhage, which affects the function of the nervous system. In addition, six-month preterm infants have an imperfect digestive system and poor sucking ability, so they need to rely on nasal feeding or parenteral intravenous nutritional support, and are prone to gastric retention, vomiting, or abdominal distension. Pregnant women should pay attention to the prenatal examination during pregnancy, actively listen to the advice of professional doctors to do a comprehensive nursing care, pay attention to more rest, at the same time should be relaxed, to avoid nervousness, anxiety, any discomfort should be timely to the hospital, the doctor to clarify the diagnosis, and cooperate with the doctor to deal with the symptoms.
