Incidence of fetal bradycardia and effect of placental injury on fetal heart rate during second-trimester genetic amniocentesis

The monitoring of fetal heart being essential in the second trimester of the prenatal periods. The abnormalities in the child heart rate has to be identified in the early stages, so as to take essential remedies for the babies in the womb, or would enable the physician to be ready for he complication on the delivery and the further treatment after the baby is received. The traditional methodologies being ineffective in detecting the abnormalities leading to fatalities, paves way for the granular computing based fuzzy set, that requires only a limited set of data for training, and helps in the eluding of the unwanted data set that are far beyond the optimal. Further the methods performance is analyzed to evident the improvement in the fetal heart rate detection in terms of prediction accuracy and the detection accuracy.

History Of

Dengue and chikungunya infections are commonly encountered by the clinicians in a tropical country like India. We report this case to emphasize the rare manifestations of self-limiting intrapartum bradycardia in fetuses of chikungunya and dengue infected mothers. A primigravida at 32 weeks of gestation presented with history of fever for one day. The blood investigations were positive for both dengue and chikungunya virus infection. On the third day of fever, NST showed a low baseline fetal heart rate of 95 to 100 beats per minute but good beat to beat variability and three accelerations in 10 minutes. This pattern persisted for 48 hours. Although, the finding initially appeared alarming, the change in baseline heart rate of fetus was transient and self-limiting and recovered completely. Hence, a judicious approach and close fetal surveillance can avoid hasty decisions regarding an early termination of pregnancy.
