简要总结
the study will examine the effect of application of intermittent pneumatic pressure device on lower limbs on the amniotic fluid amount and fetal doppler indices in women with oligohydramnios
详细描述
oligohydramnios is diagnosed based on ultrasonographic finding of amniotic fluid index less than 5 cm.
Etiologies of oligohydramnios includes infection with viruses such as rubella, cytomegalo virus or parasites such as toxoplasma. other etiologies includes rupture of membranes or fetal malformatios especially urinary tract anomalies. in addition, placental insuffiency may lead to oligohydramnios and can be diagnosed through abnormal doppler measures in the umbilical and middle cereberal arteries. when these etiologies are excluded oligohydramnios is considered to be idiopathic.
The Kendall SCD™ 700 Smart Compression™ Controller is an intermittent pneumatic compression (IPC) device which delivers compression to the legs and feet to aid in the prevention of Venous Thromboembolism in at-risk patient.
previous studies had shown that intermittent pneumatic compression device may increase cardiac output through preload increase.
the study hypothesis that after the application of IPC there will be an improvement in the preload and cardiac which will lead to an increase in placental perfusion and eventually will lead to increase in amniotic fluid amount and improvement in fetal doppler measurement.

结局指标
主要结局
pulsatility index in fetal middle cerebral artery
时间窗: one hour
Pulsed wave high-resolution color Doppler uhrasonography will be used to identify and to obtain blood flow velocity waveforms. PI will be calculated from the difference in the systolic and diastolic flow velocity divided by the mean flow velocity baseline PI of the fetal middle cerebral artery will be calculated before the application of IPC on lower maternal limbs PI of the fetal middle cerebral artery will be re-calculated after the application of IPC on lower maternal limbs for one hour
amniotic fluid index
时间窗: one hour
basline amniotic fluid index (AFI in centemeters) will be calculated before the application of IPC on lower maternal limbs amniotic fluid index (AFI in centemeters) will be re-calculated after the application of IPC on lower maternal limbs for one hour
pulsatility index in maternal uterine artery
时间窗: one hour
