Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ultrasound measurement of amniotic fluid volume as regular part of antepartum assessment of fetal well-being is done by the SDP method.
In order to calculate the SDP, the largest vertical diameter of a fluid pocket (not containing small fetal parts or loops of umbilical cord) is measured by two perpendicular diameters.
Oligohydramnios is diagnosed if there was no SDP of 2 x 1 cm.
Once a patient was assigned to SDP arm, all subsequent assessments of amniotic fluid were done accordingly.
The amniotic fluid estimation used for this evaluation is the last volume within 3 days of delivery.

Diagnosis / Prognosis
Comparator / control treatment
Ultrasound measurement of amniotic fluid volume as regular part of antepartum assessment of fetal well-being is done by the AFI method.
In order to calculate the AFI, the operator divides the uterine cavity into four quadrants. In each quadrant, the largest vertical diameter of a fluid pocket (not containing small fetal parts or loops of umbilical cord) is measured.
The sum of these four measures provides a single value for the AFI.
Oligohydramnios is diagnosed if the AFI was under 5.1 cm.
Once a patient was assigned to AFI arm, all subsequent assessments of amniotic fluid were done accordingly.
The amniotic fluid estimation used for this evaluation is the last volume within 3 days of delivery.
