IntroductionPolyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac which can be seen in 1%-2% of women. The overall prevalence of this condition is reported on 750 pregnancies. Patients suffered from polyhydramnios often referred to hospitals complaining about discomfort in the abdomen and respiratory distress. Abnormal magnitude of the uterus (compared to gestational age) along with difficulty touching embryonic organs and problems associated with fetus auscultation can be observed on physical examination. A definitive diagnosis is ultimately possible through ultrasound and by measuring the ammonic fluid index. Amniotic fluid index (AFI) more than 25 cm is considered as polyhydramnios, accordingly (1).Polyhydramnios may be associated with fetal and maternal complications such as respiratory distress, thromboembolism, preterm labor, atonic uterus, anemia, caesarean section, premature fetus, umbilical cord prolapse caused by the rupture of the membranes and fetal distress (2-4).Common treatment methods of polyhydramnios pregnancies include examination of maternal risk factors (diabetes, viral hepatitis, syphilis and other torch infections and addiction) and examination of fetal risk factors (hydrops fetalis, esophageal atresia, gastroschisis, anencephaly, diaphragmatic hernia, placental chorioangioma, severe anemia, heart problems and chromosomal abnormalities). In mild cases, simple control and follow-ups, continuous ultrasound and conservative treatment methods AbstractObjectives: Polyhydramnios is a condition that could be along with significant maternal, fetal and neonatal consequences. One of the most important complications of this condition is preterm labor and delivery of preterm neonates. Although in mild cases expectant conservative management is effective, in more severe cases, medications (such as indomethacin) and amnioreduction could be considered. Each one of these methods could be accompanied with complications. This study aims to examine the results of management of patients with polyhydramnios according to the fetal and maternal distress and preterm labor criteria. Materials and Methods: In this descriptive-analytic setting, 26 pregnant mothers with polyhydramnios (amniotic fluid index [AFI] more than 30) were managed according to the fetal and maternal distress and preterm labor criteria. In cases under 32 gestational weeks, indomethacin was used with an initial dose of 25 mg every 6 hours and a maximum dose of 2-3 mg/kg that was tapered when the AFI diminished. In refractory cases, the flowchart of fetal and maternal distress and preterm labor was employed. In pregnancies aged over 32 weeks, in case of maternal distress amnioreduction was performed, and in asymptomatic patients, cervical length, funneling, color Doppler and placental thickness were evaluated and in normal cases controlling was carried every 1-2 weeks and abnormal cases amnioreduction was carried out. Results: The mean age of studies patients was 28.12 ± 7.22 years and the mean pregnanc...

“…In 358 pregnant women with polyhydramnios, Queenan and Gadow [2]found that 24.6% had diabetes mellitus, 11.5% had erythroblastosis fetalis, 8.4% had multiple births, 1.5% had acute polyhydramnios, and 20% had congenital anomalies; in 34% of these cases polyhydramnios was idiopathic. However, few studies were performed on the relationship between polyhydramnios and congenital anomalies and most of them were on at risk pregnancies [3, 4, 5, 6, 7, 8, 9, 10, 11]. Since the landmark report of Queenan and Gadow [2], the definition of polyhydramnios has shifted from a clinical to an ultrasonographic one.…”

Objectives: To provide data on polyhydramnios associated with congenital anomalies in 225,669 consecutive pregnancies. Material and Methods: The information in this study came from births of known outcome recorded in our registry of congenital malformations. Routine ultrasonographic examination was performed. Polyhydramnios was diagnosed ultrasonographically. A case-control study allowed the examination of genetic and environmental causal factors of polyhydramnios associated with congenital malformations. Results: The prevalence of this association was 1.28/1,000 (290 cases). Polyhydramnios associated with congenital malformations was diagnosed prenatally in 44.5% of the cases, 10.3% of the infants were stillborn. Forty-one percent of the cases had more than one malformation, 14.5% had a chromosomal aberration, and 20.0% had multiple malformations that do not constitute a syndrome. The more frequent malformations associated with polyhydramnios were cardiac, digestive, central nervous system, musculoskeletal, and urinary. There was increased parental consanguinity. The incidence of polyhydramnios and congenital anomalies among first-degree relatives was 4.1% and first-degree relatives had more malformations than controls (6.2 vs. 3.2%, p < 0.05). Threatened abortions and diabetes mellitus were significantly more frequent among mothers of children with congenital malformations associated with polyhydramnios than among controls. Conclusions: Our study demonstrated that careful fetal examination has to be performed when polyhydramnios is diagnosed as congenital malformations are often associated with polyhydramnios. We recommend the use of fetal chromosome analysis and careful ultrasonographic examination in every pregnancy complicated by polyhydramnios.

“…al. (1995) [7] reported that 20% of 275 women with an AFI of 25 cm delivered preterm and it were more common with anomalous fetus 40%. Malpresentation was seen in three cases (10%) in this study two cases were seen in severe polyhydramnios one was breech and the other was compound presentation.…”

The association between polyhydramnios and preterm delivery

Abstract: The underlying cause of polyhydramnios, rather than the relative excess of amniotic fluid as defined by this study, appears to determine when preterm labor will occur.
