WebJan 30, 2024 · Late deceleration is defined as a visually apparent, gradual decrease in the fetal heart rate typically following the uterine contraction. The gradual decrease is defined as, from onset to nadir taking 30 seconds or more. WebWith constantly increasing incidence, it is estimated to increase to 6.3 million worldwide by the year 2050. 1 Despite advances in surgical technique, the surgery is still associated with high mortality rate and frequent postoperative cardiac complications in elderly patients with hip fracture. 2 The mortality rate was reported as high as 4 ...

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.) Early Decelerations Early decelerations are periodic slowing of the fetal heartbeat, synchronized exactly with the contractions. Accelerations are short-term increases in fetal heart rate by at least 15 beats per minute (bpm) that last at least 15 seconds. These accelerations occur at different times throughout labor and delivery and are a sign that the fetus has an adequate supply of oxygen. See more There are three types of deceleration that may occur during labor. Each type is categorized by the timing of the deceleration during uterine contractions.1 See more Electronic fetal heart rate monitoring can be used to evaluate the overall health of the fetus during labor. The primary benefit of monitoring is early detection of fetal distress, but there is … See more The cause of deceleration varies depending on the type. For example, early decelerations are caused by the compression of the baby’s head during uterine contractions. … See more
