The survival rate of a 1000 gram preterm baby is low, but if the preterm baby’s lungs are well developed and there are no complications, it is possible for the preterm baby to survive. Since the body tissues and organs of a preterm baby are not yet well developed, the chances of survival are low, and a slight choking or infection may take away the life of a preterm baby. However, if the preterm baby is carefully cared for, and the lungs and digestive system are well developed, the baby can breathe and feed normally, and can survive. The presence of complications is crucial for the survival of the fetus, and a 1000 gram preemie has a lower chance of survival if there are multiple complications, such as lung infections, pulmonary atelectasis, necrotizing small bowel colitis, and other conditions. Whether or not a 1000 gram preterm baby will survive is related to a number of factors, and parents are advised to take care of the baby carefully under the guidance of a healthcare professional.
