Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Upright maternal position change

The participant will be measured by ultrasonograhy for amniotic fluid index in supine position before maternal position change, then she will do the upright position for 5 minute. After 5 minute of upright position , she will lie down in supine position and she will be measured by ultrasonograhy for amniotic fluid index after upright position.

Group Type EXPERIMENTAL

Amniotic fluid index

Intervention Type DIAGNOSTIC_TEST

Ultrasonography of the amniotic fluid level in each 4 quadrants of uterus then summerize as one value to measure the quantity of amniotic fluid index

Left lateral decubitus maternal position change

the participant will be measured by ultrasonograhy for amniotic fluid index in supine position before maternal position change, then she will do the left lateral decubitus position for 5 minutes. After 5 minutes of left lateral decubitus position , she will lie down in supine position and she will be measured by ultrasonograhy for amniotic fluid index after left lateral decubitus position.
