Fetal heart rate response to maternal hypotension during amniocentesis

Ten cases of severe fetal heart rate deceleration following maternal vaso-vagal reflex during amniocentesis were presented. The good outcome of these fetuses suggests that this transient phenomenon has no adverse effect on the fetus. This type of FHR response should be recognized so as to avoid unnecessary Caesarian sections done because of severe FHR bradycardia following amniocentesis.
