Polyhydramnios is linked to complications such as placental abruption, preterm labor, congenital anomalies, and postpartum hemorrhage, emphasizing the need for early detection and management. While idiopathic causes account for 60%\u201370% of cases, other causes include impaired fetal swallowing and increased urine production due to maternal, fetal, and placental conditions. Accurate amniotic fluid volume (AFV) assessment and surveying the underlying cause are important, with ultrasound methods such as deep vertical pocket (DVP) and amniotic fluid index (AFI) preferred. Polyhydramnios is defined by an AFV exceeding 2000 ml, an AFI over 24 cm, or DVP more than 8 cm. Management typically targets underlying causes, with treatments such as amnioreduction and indomethacin for severe cases. Antepartum monitoring includes detailed fetal ultrasound, genomic and genetic examinations, and tests for maternal diabetes and infections. Intrapartum management addresses complications such as malpresentation and shoulder dystocia, whereas postpartum care involves monitoring for uterine atony and hemorrhage. Perinatal outcomes in idiopathic polyhydramnios are generally poorer, with increased risks of fetal demise, preterm delivery, and neonatal complications, but these results may need further stratification and verification.<\/jats:p>","DOI":"10.4103\/jmu.jmu_83_24","type":"journal-article","created":{"date-parts":[[2024,11,30]],"date-time":"2024-11-30T00:00:18Z","timestamp":1732924818000},"page":"285-290","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":6,"title":["Too Much of a Good Thing: Updated Current Management and Perinatal Outcomes of Polyhydramnios"],"prefix":"10.4103","volume":"32","author":[{"given":"Fang-Tzu","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Mackay Memorial Hospital, Taipei, Taiwan"},{"name":"Department of Medicine, Mackay Medical College, New Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chih-Ping","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Mackay Memorial Hospital, Taipei, Taiwan"},{"name":"Department of Medical Research, Mackay Memorial Hospital, Taipei, Taiwan"},{"name":"School of Chinese Medicine, College of Chinese Medicine, China Medical University, Taichung, Taiwan"},{"name":"Institute of Clinical and Community Health Nursing, National Yang-Ming Chiao-Tung University, Taipei, Taiwan"},{"name":"Department of Obstetrics and Gynecology, School of Medicine, National Yang-Ming Chiao-Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2024,11,30]]},"reference":[{"key":"R1-20260724","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1186\/s13256-024-04435-0","article-title":"Polyhydramnios associated with rare genetic syndromes: Two case reports","volume":"18","author":"Lim","year":"2024","journal-title":"J Med Case Rep"},{"key":"R2-20260724","doi-asserted-by":"crossref","first-page":"2827","DOI":"10.1002\/jum.15970","article-title":"Moderate-to-severe Polyhydramnios: Cutoffs for deepest vertical pocket corresponding to amniotic fluid index","volume":"41","author":"Qureshey","year":"2022","journal-title":"J Ultrasound Med"},{"key":"R3-20260724","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1111\/ajo.12578","article-title":"Outcome of pregnancy in women diagnosed with idiopathic Polyhydramnios","volume":"57","author":"Khan","year":"2017","journal-title":"Aust N Z J Obstet Gynaecol"},{"key":"R4-20260724","doi-asserted-by":"crossref","first-page":"B2","DOI":"10.1016\/j.ajog.2018.07.016","article-title":"SMFM consult series #46: Evaluation and management of Polyhydramnios","volume":"219","year":"2018","journal-title":"Am J Obstet Gynecol"},{"key":"R5-20260724","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1016\/j.bpobgyn.2016.08.004","article-title":"Antenatal fetal surveillance \u201cassessment of the AFV\u201d","volume":"38","author":"Hughes","year":"2017","journal-title":"Best Pract Res Clin Obstet Gynaecol"},{"key":"R6-20260724","doi-asserted-by":"crossref","first-page":"e81824","DOI":"10.1371\/journal.pone.0081824","article-title":"Amniotic fluid deficiency and congenital abnormalities both influence fluctuating asymmetry in developing limbs of human deceased fetuses","volume":"8","author":"ten Broek","year":"2013","journal-title":"PLoS One"},{"key":"R7-20260724","doi-asserted-by":"crossref","first-page":"816","DOI":"10.1016\/j.placenta.2006.11.009","article-title":"Amniotic fluid water dynamics","volume":"28","author":"Beall","year":"2007","journal-title":"Placenta"},{"key":"R8-20260724","doi-asserted-by":"crossref","first-page":"266","DOI":"10.1016\/0002-9378(66)90178-5","article-title":"Preliminary data on the use of sodium aminohippurate to determine amniotic fluid volumes","volume":"95","author":"Charles","year":"1966","journal-title":"Am J Obstet Gynecol"},{"key":"R9-20260724","doi-asserted-by":"crossref","first-page":"1353","DOI":"10.7863\/ultra.33.8.1353","article-title":"A systematic review of amniotic fluid assessments in twin pregnancies","volume":"33","author":"Ippolito","year":"2014","journal-title":"J Ultrasound Med"},{"key":"R10-20260724","doi-asserted-by":"crossref","first-page":"e241","DOI":"10.1097\/AOG.0000000000001815","article-title":"Practice bulletin no. 175.
