Sentence examples for late deceleration from inspiring English sources

The critical periods for late deceleration with loss of variability and for prolonged deceleration were 60 and 30 min, respectively.

Umbilical pH values in fetuses with persistent late deceleration with loss of variability (7.15±0.11, P<0.01) and in those with prolonged deceleration (7.17±0.16, P<0.01) were significantly lower than in fetuses with reassuring FHR patterns (7.29±0.06).

All asphyxiated newborns were delivered by emergency cesarean section due to acute fetal distress, defined according to the American College of Obstetricians and Gynecologists as non-reassuring fetal status (bradycardia, late deceleration of the fetal heart rate, severe and repetitive variable deceleration of the fetal heart rate, reduced beat-to-beat variability).

Late decelerations and severe variable decelerations were significant factors associated with fetal acidosis.

The fetal heart rate pattern in 13 cases showed bradycardia and repetitive variable or late decelerations.

Conclusion: Subendocardial injury occurs after severe repeated intrauterine asphyxia in the late-gestation fetus, and this may contribute to cardiovascular compromise and the development of late decelerations.

Results: Patients with normal variability and accelerations, even in the presence of late decelerations or variable decelerations, maintained an umbilical artery pH 7.0 or greater in more than 97% of cases.

The patients were placed in six groups, depending on the absence or presence of normal variability (amplitude >5 beats) during the last hour of monitoring combined with the absence of decelerations or the presence of variable or late decelerations.

Decelerations in labor (P =.597), late decelerations (P =.999), cesarean deliveries for fetal distress (P =.413), and umbilical cord pH < 7.2 were similar (P =.647) Conclusion: Ultrasound-estimated and dye-determined amniotic fluid volumes are similar between upper-greater and lower-greater groups, and intrapartum/neonatal outcomes are not affected by the amniotic fluid distribution.

Conclusion: The most significant intrapartum fetal heart rate parameter to predict the development of significant acidemia is the presence of minimal/absent variability for at least 1 hour as a solitary abnormal finding or in conjunction with late decelerations in the absence of accelerations.

Exclusion criteria included: viral infections (human immunodeficiency virus or hepatitis), anhydramnios and presence of fetal heart rate abnormalities (bradycardia, recurrent variable and late decelerations) requiring emergency intervention.
