WebFeb 17, 2024 · Late Deceleration Late deceleration of the FHR is a gradual decrease of greater than 30 seconds to nadir and return to baseline associated with a uterine contraction, but the nadir occurs after the contraction. Late decelerations are nonreassuring, indicating uteroplacental insufficiency. WebNov 26, 2024 · Late deceleration Pelvic large iliac arteries were compressed by contracted uterus in the labor at supine posture, stopping placental arterial blood supply, developing fetal hypoxia and the deceleration after contraction (Poseiro effect). The pelvic angiography revealed the fact. The LD disappeared after maternal lateral posture [3]. 3). WebEach has its own features and clinical significance. In addition, a fetus may demonstrate combined decelerations (for example, a severe variable deceleration with a late deceleration component.)
