Panda blood usually refers to RH-negative blood, and RH-negative blood flow in one pregnancy may or may not be normal in the second pregnancy. Because RH negative blood second child is prone to hemolysis of the newborn, so when pregnant with the second child should pay attention to check the antibody. If the pregnant woman is RH-negative blood, the pregnant woman’s spouse with and the pregnant woman’s blood type is not the same, there may be maternal and embryonic blood type incompatibility, so the fetus is prone to hemolysis. In the first pregnancy, the pregnant woman has antibodies against the embryonic blood, so the possibility of hemolysis is small, but in the second pregnancy, there is no more protection from the antibodies, and the probability of hemolysis is larger. Abortion is a surgical procedure to terminate pregnancy by inducing uterine contractions through artificial means. After having an abortion for the first pregnancy, it is important to check for antibodies when you are pregnant with your second child. If the antibody level is high, medication needs to be applied to lower the antibody in order to reduce the probability of hemolytic disease after the birth of the fetus. During pregnancy, you should keep a good mood, don’t smoke and have a balanced diet. Do a combination of work and rest, do not stay up late, and maintain sufficient rest. In addition, if the pregnant woman is not feeling well, it is recommended to go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
