The biophysical profile in multiple pregnancy

The high risk attributed to multiples calls for close observation during pregnancy. Based on adequate predictions in singletons, it was expected that the biophysical profile (reactive fetal heart rate pattern on non-stress test, presence of fetal breathing and body movements, documentation of normal fetal tone and adequate amount of amniotic fluid) could be used in multiples as well. However, the paucity of studies could not demonstrate an equivalent predictive capacity in multiple pregnancies.
