Analysis of pregnancy outcome of category Ⅱ fetal heart rate tracing / 重庆医学

ABSTRACT

Objective To explore the potential risk of category Ⅱ fetal heart rate(FHR) tracing according to the latest electron-ic fetal monitoring tracings .Methods The prenatal fetal heart rate tracings in 400 parturients with hospitalized delivery in this hos-pital from November 2011 to October 2012 were classified by category .Among them ,the pregnancy outcomes were compared be-tween the category Ⅰ FHR tracings(control group) and category Ⅱ FHR tracings(observation group) .Results The case number of meconium-staining amniotic fluid ,cesarean rate ,hypamniony and umbilical cord abnormality was significantly higher than that of the control group with statistical difference between the two groups (P0 .05);among the groups with various fetal heart monitoring abnormalities ,the rate of meconium-staining amniotic fluid in the decreased variation group was significantly higher than that in the fetal tachycardia group ,the difference showing statistical significance (P<0 .05);the rate of meconium-staining amniotic fluid in the fetal tachycardia group was significantly higher than that in the prolonged acceleration and ineffective acceleration group with statistical difference (P< 0 .05);the pregnant outcomes had no statistical differences among the other groups .Conclusion Compared with the category Ⅰ FHR tracings ,the category Ⅱ FHR tracings indicate a potential risk to the fetus ,which need to strengthen the prenatal and intrapartum fetal monitoring .
