Can a premature infant born at 26 weeks weighing only 1.6 pounds survive?

　　A 26-week preterm infant weighing only 1 pound 6 taels (approximately 720 grams) faces a high risk of survival, but it is still possible to survive. If the preterm infant's growth and development are in good condition after birth, the survival rate will be relatively higher. However, if development is immature, the survival rate will decrease. After birth, preterm infants should receive continuous monitoring and treatment from an experienced medical team.

　　1. Good growth and development: If the preterm infant's weight, length, head circumference, and other indicators increase steadily, and no significant complications occur, the survival rate will be relatively higher.

　　2. Immature development: At such a low birth weight, the infant's organs may be extremely immature, especially the lungs, which can lead to respiratory failure and other life-threatening conditions, such as respiratory distress syndrome, intracranial hemorrhage, sepsis, and necrotizing enterocolitis.

　　In addition, medical conditions can also affect the survival of preterm infants. In medical institutions with advanced equipment and skilled medical techniques, preterm infants can receive timely medical interventions and life support.

　　Pregnant women should maintain a positive and optimistic mindset, follow a balanced diet, engage in appropriate physical activity, undergo regular prenatal checkups, and follow professional medical advice to ensure the health of both mother and baby.
