Every pregnancy where there is more than one fetus in the uterus is called the multiple pregnancy. The most frequent multiple pregnancies are twin pregnancies, but because of more infertility treatment there is a higher frequency of pregnancies with more than one fetus. Twin pregnancies can be monozygotic and dizygotic. Monozygotic twins are developed from one fertilized egg that is fertilized by one sperm and therefore the DNA of those twins is identical. Dizygotic are developed from two fertilized eggs that are fertilized by two sperms and therefore the DNA in those twins is different. The diagnosis of multiple pregnancy is made with anamnesis, clinical and ultrasound examination. It is very important to know whether the mother is a twin or if there are twins in the family or if the mother was treated because of infertility. The safest confirmation is that of ultrasound examination. Health care of a woman with multiple pregnancy is similar to the care of a woman with single pregnancy, but with more supervision. Prenatal care is the same as in single fetus pregnancy, but amniocentesis is more frequent. During the perinatal care midwife has the role of an educator. She advises to the pregnant woman proper healthy nutrition rich with iron and vitamins. If there are no contraindications, pregnant woman is advised to do leisure activities like walking, but in certain periods. It is very important to have regular and proper supervision of the children during pregnancy. Emphasis is put on the tracking of the growth and oxygenation of the fetuses. It is very important during this to know the exact duration of the pregnancy. During this supervision the golden standard is the cardiotocography. Multiple pregnancies are shorter than other pregnancies. Twin pregnancies can end spontaneously or with a caesarean section. To prevent possible complications, in multiple pregnancies we often immediately move with the caesarean. It is better that these pregnancies are ended in tertiary perinatal centres. The midwife has one of the main roles during the birth and therefore she must be an expert in both theory and practice. But she has the more important role during the period of puerperium –when she is the main consultor of the new mother. The midwife is the mediator between the mother and her environment and makes it clear to the family, and especially to the partner, that the woman in labour is in need of support and help in her new role. The midwife needs to educate the new mother about correct breastfeeding/expressing breast milk, doing personal hygiene and underline what about she needs to be careful when doing everyday activities. She should educate the new mother how to care for the children, especially cleaning the navel during the first days and, moreover, the benefits of mother’s milk for the children and the mother herself. 7.
