Introduction
In general, twin-to-twin transfusion syndrome is a serious complication occurring in monochorionic twin pregnancies. After surgery, closely monitor the babies' breathing, heart rate, and body temperature; seek immediate medical attention if rapid breathing, abnormal temperature, or other issues are observed. Adjust feeding amounts according to the babies' weight and health status, using a method of small, frequent feedings to ensure adequate nutrition.
In general, twin-to-twin transfusion syndrome (TTTS) is a serious complication that occurs in monochorionic twin pregnancies. The specific analysis is as follows:
TTTS mostly occurs in monochorionic diamniotic twin pregnancies. Because the two fetuses share a single placenta, abnormal vascular anastomoses within the placenta lead to an imbalance in blood distribution. The donor twin transfers excessive blood to the recipient twin, resulting in growth restriction, oligohydramnios, and even heart failure in itself. Conversely, the recipient twin suffers from hypervolemia, which may lead to cardiac overload, polyhydramnios, and fetal hydrops. Without timely intervention, TTTS poses a severe threat to the health and survival of both fetuses.
After surgery, closely monitor the baby's breathing, heart rate, and body temperature. Seek immediate medical attention if symptoms such as rapid breathing or abnormal temperature are observed. Adjust feeding amounts according to the baby’s weight and health status, using a strategy of small, frequent feedings to ensure adequate nutrition. Keep the baby’s skin clean and dry, and handle gently during diaper changes to prevent skin damage. Provide a quiet and comfortable resting environment, minimize external stimuli, ensure the baby gets sufficient sleep, and support recovery of bodily functions.
