Brief Summary

Comparison of amniotic fluid index between before and after maternal position change in Upright and left lateral decubitus maternal position

Detailed Description

Amniotic fluid has many important roles in fetal development such as the development of the digestive tract and respiratory system. The quantity of amniotic fluid can be measured by ultrasonography, measuring the deepest pocket in 4 quadrants of uterus then summarize as one value known as "amniotic fluid index"(AFI). The AFI has the normal range between 5-25 cm. The low AFI (\< 5 cm) is associated with abnormal fetal heart rate, and the abnormal AFI does affect to the treatment during the antepartum and intrapartum phase. However , there is the study shown that when compared to the single deepest pocket (SDP) , AFI could detect the oligohydramnios more which might led to the unnecessary labor induction or operative delivery without the significant change of perinatal outcome. To increase the accuracy of AFI, we theorize that maternal position change might affect the amniotic fluid position which would increase the visual of the amniotic fluid as well.
