ABSTRACT
Many biophysical techniques are used to assess fetal well-being in multiple pregnancy, including ultrasonography, Doppler velocimetry and cardiotocography. Considering the specific characteristics of multiple pregnancies in terms of higher rate of preterm delivery, higher incidence of fetal growth restriction and higher rates of obstetric complications as compared with singleton gestation, as well as specific problems related to chorionicity and to the number of fetuses, it is difficult to summarize generally the usefulness and role of each technique, or to provide a general standard of management. Rather, it is advisable to assess and manage each case individually on the basis of the presence of recognized risk factors, making use of each technique or of a combination of different techniques according to the specific information desired. These complexities also demand that the information obtained should be interpreted on the basis of a thorough understanding of the pathophysiology involved.
