Late Decelerations (labor and delivery). A âdecelerationâ describes a decrease in the heart rate of the fetus from its baseline heartrate. âLate decelerationsâ are described as a transient decrease in the fetal heart rate occurring at or after the peak of a uterine contraction. Late decelerations may represent some degree of utero-placental insufficiency. All blood flow in and out of the intravillious space stops briefly during a contraction.
Fetal bradycardia is defined as a baseline fetal heart rate less than 110 beats per minute for at least 10 minutes. Evaluation and management differs for antenatal and intrapartum fetal bradycardia. Fetal heart rate variability provides further information regarding the implications of bradycardia for fetal status. The most common causes of intrapartum bradycardia include poor uterine perfusion, maternal hypotension (e.g. after epidural placement), umbilical cord prolapse or occlusion, rapid fetal descent, tachysystole, placental abruption, or uterine rupture.
