Pathophysiology Of Fetal Heart Rate And The Influence Of Electronic Fetal Monitoring On Pregnancy Outcome

Objective: 1.To understand the pathophysiology of fetal heart rate.2.To analysis the accuracy of intrauterine fetal condition and the influence on pregnancy outcome of electronic fetal monitoring tracings.Methods: 1.To summarize the pathophysiology of fetal heart rate according to the basis of diversified literatures.2.The objects of this study are derived from the population delivery at the clinic of the hospital from January 2016 to February 2016.They are grouped according to the non-stress test electronic fetal monitoring tracings and the latest NICHD electronic fetal monitoring tracings.Their pregnancy outcomes were recorded.Statistical analysis was performed to explore their relationships and differences.Results: 1.Physiologic control of the fetal heart rate can be divided loosely into three types of influences: those that are extrinsic to the fetus,those that are intrinsic to the fetus,and those that represent the homeostatic interaction between the fetus and its environment.2.The case number of the non-stress test electronic fetal monitoring tracings and the latest NICHD electronic fetal monitoring tracings had significant correlation(P?0.05).The case number of meconium-staining amniotic fluid and different types of deceleration had significant correlation(P?0.05).The case number of neonatal asphyxia had significant correlation(P>0.05).Conclusion: 1.The latest NICHD electronic fetal monitoring tracings is better than the non-stress test electronic fetal monitoring tracings since it can reduce unnecessary clinical interventions 2.The change of fetal heart rate can prompt the intrauterine fetal anoxia indirectly.We should also consider the homeostatic interaction between the fetus and its environment...
