Antenatal Surveillance in Twin Pregnancies Using the Biophysical Profile
Twin pregnancies are at increased for stillbirth and warrant close surveillance, particularly towards the end of pregnancy. In singleton pregnancies, it has been shown that a Biophysical profile (BPP), which is an ultrasound assessment of fetal well-being, is superior to a NonStress Test (NST), which involves 20-40 minutes of fetal heart rate monitoring. In this study, we examined the utility of BPP testing in twin pregnancies and found that a normal test is associated with an extremely low rate of stillbirth and that there are few false positive results (false scares).
