Although most cases have normal amniotic fluid volume, some cases present with early oligohydramnios and renal failure associated with high perinatal mortality. [ncbi.nlm.nih.gov]

Assuming all is well and the presenting part well engaged in the pelvis, we are then past the problems of presentation, cord prolapse and greatest danger of placental abruption. [gentlebirth.org]

Intrapartum management Rates of fetal nonvertex presentation are reported to increase as severity of polyhydramnios increases. Clinical or sonographic determination of the fetal presenting part should be performed upon presentation in labor. [contemporaryobgyn.net]

The patient may clinically present as a large for dates uterus. Polyhydramnios occurs as a result of either increased production or decreased removal of amniotic fluid. [radiopaedia.org]

• Burkina Faso

  PATIENTS AND METHODS: A retrospective multicentre study over a three-year period carried out in Ivory Coast and Burkina Faso. We reviewed 3903 obstetric ultrasound reports. All cases of foetal malformation and polyhydramnios were counted. [ncbi.nlm.nih.gov]

• Dyspnea

  […] polyhydramnios in singleton pregnancies be defined as either a deepest vertical pocket of
  8 cm or an amniotic fluid index of
  24 cm (GRADE 2C); (2) we recommend that amnioreduction be considered only for the indication of severe maternal discomfort, dyspnea [smfm.org]

  […] moderate: single deepest pocket at 12-15 cm or AFI 30.1-35 severe: single deepest pocket >16 cm or AFI >35 The risk of the following obstetric complications is increased when polyhydramnios is present due to over-expansion of the uterus13: maternal dyspnea [radiopaedia.org]

  In the mother, the physician may observe increased abdominal size out of proportion for her weight gain and gestation age, uterine size that outpaces gestational age, shiny skin with stria (seen mostly in severe polyhydramnios), dyspnea, and chest heaviness [en.wikipedia.org]

  Polyhydramnios can result in: Preterm labour and premature rupture of the membranes Maternal discomfort and dyspnea (difficulty breathing) due to uterine overdistension, i.e over-expansion. [isuog.org]

• Mediastinal Shift

  The procedure not only decompressed the lung cyst but also improved the secondary physiological changes, i.e. mediastinal shift, hydrops and polyhydramnios. [ncbi.nlm.nih.gov]

Even after the discontinuation of NSAID treatment, the amniotic fluid production normalized, and the woman delivered a healthy boy at 39 weeks 2 days' gestation. [ncbi.nlm.nih.gov]

[…] for polyhydramnios Usually, mild polyhydramnios may need no treatment as it will go away on its own. [hellodoktor.com]

Treatment depends on the severity of the condition and varies from person to person. Every woman and her baby will react differently to a treatment method. [consumerhealthdigest.com]

Further treatment may not be needed. [lahey.org]

If polyhydramnios is not associated with any other findings, the prognosis is usually good. [emedicine.medscape.com]

We examined the relationships between polyhydramnios, pregnancy outcome and fetal prognosis. PATIENTS AND METHODS: Clinical data from cases diagnosed antenatally with congenital omphalocele from 1993 to 2006 were analyzed retrospectively. [ncbi.nlm.nih.gov]

Prognosis The prognosis for both polyhydramnios and oligohydramnios depends on the cause. If excess or reduced amniotic fluid is the result of an underlying fetal abnormality, the nature of that abnormality will determine the prognosis. [medical-dictionary.thefreedictionary.com]

Etiology- Fetal Anencephaly Esophageal atresia Spina Bifida Cleft lip & Palate Hydrocephalus Aneuploidy 6. Etiology- Placental Normal Placenta Chorioangioma 7. Etiology- Multiple pregnancy 8. Etiology- Maternal Maternal diabetes 9. [slideshare.net]

When an etiology of polyhydramnios is identified, it is most commonly a fetal anomaly or maternal diabetes. [contemporaryobgyn.net]

The likelihood that polyhydramnios is associated with a distinct identifiable etiology depends upon its severity. [cancertherapyadvisor.com]

The etiology of polyhydramnios may be idiopathic, the consequence of fetal structural anomalies, or the consequence of various fetal and maternal conditions. [ncbi.nlm.nih.gov]

Fetal goiter is only rarely observed in pregnant women without autoimmune thyroid disorders, and there is no epidemiological data on its pathophysiology. [ncbi.nlm.nih.gov]

Maternal metabolic abnormalities such as hypercalcaemia.[2] Epidemiology[3] There are few recent studies but polyhydramnios is said to affect 0.2-1.6% of all pregnancies. [patient.info]

Section 1: Epidemiology and aetiology In pregnancy, the amniotic sac contains the fetus surrounded by amniotic fluid. Initially amniotic fluid is maternal body water partitioned in the fetoplacental extracellular space. [gponline.com]

Understanding the epidemiology of polyhydramnios in LMICs might lead to strategies for reducing perinatal and peripartum morbidity and mortality. [bmcpregnancychildbirth.biomedcentral.com]

But their roles in the pathophysiology of polyhydramnios are unclear. [ncbi.nlm.nih.gov]

Polyhydramnios is over the 95th centile, oligohydramnios is below the 5th centile Pathophysiology The volume of amniotic fluid increases steadily until 33 weeks of gestation. [teachmeobgyn.com]

Antenatal fetal cyst decompression successfully reversed the polyhydramnios and prevented premature delivery, resulting in a full-term healthy infant delivered vaginally at thirty-nine weeks. [ncbi.nlm.nih.gov]

Prevention In order to prevent polyhydramnios or oligohydramnios, it would be necessary to prevent the underlying cause. [medical-dictionary.thefreedictionary.com]

You may not be able to prevent polyhydramnios. The following may lower the risk: Do not smoke. Nicotine increases the risk for problems with your pregnancy and your baby's health. [drugs.com]
