OBJECTIVE: To determine the effect of maternal hydration with intravenous (i.v.) isotonic fluid, i.v. hypotonic fluid, and oral water on amniotic fluid index (AFI) in women with oligohydramnios. METHODS: Patients with low AFI and gestational age over 35 weeks without maternal complications were randomized into four groups (2 L/2 h i.v. isotonic fluid, 2 L/2 [...]
OBJECTIVE: To estimate the effects of maternal intravenous hydration on amniotic fluid volume in normal pregnancies. METHODS: Women undergoing an amniocentesis for the evaluation of fetal lung maturity before an elective cesarean delivery were eligible to participate. An amniotic fluid index (AFI) was obtained before the amniocentesis, and at the time of the amniocentesis the [...]
OBJECTIVE: To evaluate the effect of long-term (1-week) oral hydration on amniotic fluid volume in women with an amniotic fluid index (AFI) < 10th percentile. STUDY DESIGN: This prospective, nonrandomized, interventional study was conducted on 30 women with AFI < 10th percentile. Study inclusion criteria were singleton pregnancy, well-established gestational age, intact membranes, no maternal [...]

OBJECTIVE: Our purpose was to determine whether acute maternal hydration in pregnancies with third-trimester oligohydramnios (1) increases amniotic fluid index and hourly fetal urine production rate and (2) alters uteroplacental perfusion and fetal blood flow. STUDY DESIGN: Ten women with third-trimester oligohydramnios (amniotic fluid index < or = 5 cm) and 10 controls with normal [...]
OBJECTIVE: To test the hypothesis that maternal oral hydration would increase the amniotic fluid (AF) index in pregnancies with normal AF. METHODS: Forty women with a normal AF index (7.0-24.0 cm) were randomized to either the control or hydration group. Women in the hydration group drank 2 L of water and returned for the post-treatment [...]
Although adequate amniotic fluid (AF) volume is considered an important aspect of fetal well-being, the etiology of decreased AF volume is not well understood. A randomized blinded trial was designed to examine our hypothesis that maternal hydration would increase the AF index in women with low AF indexes. Women seen in our testing centers were [...]
