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.
Here's a mini overview of deceleration in laborâ¦ early decelerations may be caused by head compression usually not associated with fetal compromise ; usually requires no intervention; late decelerations can be caused by uteroplacental insufficiency or impaired placental exchange the patterns look similar to early decelerations but begin well after the contraction begins and return to baseline after the contraction ends
