The prognosis of the fetus with placenta abruptio is mainly related to the number of weeks of gestation. The prognosis of full-term placenta abruptio is good if it is treated promptly and there is no obvious signs of hypoxia at birth. Premature babies born after 34 weeks of gestation have a better prognosis because the functions of all organs in the body are basically perfect and they have the ability to survive on their own. In contrast, preterm infants born before 28 weeks of gestation have a lack of lung surface active substance and may develop pulmonary hyaline membrane disease and neonatal asphyxia, but if these fetuses are treated promptly, the prognosis is also good if the fetus does not show signs of hypoxia.
