The survival rate of preterm babies born at 27 weeks is usually low, but there is no specific data, mainly related to the pregnancy condition of the pregnant woman, the general condition of the preterm baby, the hospital treatment conditions, and the degree of cooperation of the parents and other factors. If the pregnant woman is in good condition during pregnancy, the general condition of the preterm baby at 27 weeks is also good, there are no serious comorbidities such as gastrointestinal hemorrhage, cerebral hemorrhage, respiratory distress, etc., and the hospital where they are located is well equipped with medical facilities, and after the birth, the parents also actively cooperate with the hospital treatment to strengthen feeding and care, the survival rate of the baby will be increased. However, if the mother has gestational hypertension, gestational diabetes, etc. during pregnancy, the 27-week preterm baby’s general condition is not good, there are serious comorbidities, and the hospital where the medical facilities are not perfect, and after the birth of the parents failed to actively cooperate with the doctor’s treatment, etc., the survival rate may be greatly reduced. If a pregnant woman gives birth to a preterm baby at 27 weeks, it is recommended that she undergoes timely postnatal care and, under the guidance of her doctor, improves the relevant examinations to ascertain whether or not there are any comorbidities, and then takes the appropriate treatment measures.
