Methods: The studies establishing normal actual AFVs and the ultrasound estimates used to identify normal and abnormal AFVs were evaluated. Recommendations from national and international organizations were reviewed for guidance on the definitions and management of abnormal AFVs. Results: A timeline of the development of the thresholds that define abnormal AFVs was created. Recommendations from 13 national and international guidelines were identified, but the definitions and management recommendations for abnormal AFVs varied considerably between groups. An algorithm for the management of oligohydramnios and polyhydramnios was developed. Knowledge gaps and the structure of future studies were examined. Conclusions: Assessment of AFV is performed multiple times per day in antenatal clinics and hospitals. Current recommendations on defining and managing abnormal AFVs differ between national and international organizations. We have proposed algorithms to assist in the management of abnormal AFVs until further studies can be undertaken.<\/jats:p>","DOI":"10.3390\/jcm13164702","type":"journal-article","created":{"date-parts":[[2024,8,12]],"date-time":"2024-08-12T11:23:46Z","timestamp":1723461826000},"page":"4702","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Historical Assessment, Practical Management, and Future Recommendations for Abnormal Amniotic Fluid Volumes"],"prefix":"10.3390","volume":"13","author":[{"given":"Julie R.","family":"Whittington","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Navy Medicine Readiness and Training Command Portsmouth, Portsmouth, VA 23708, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suneet P.","family":"Chauhan","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston (UTHealth), Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8116-5613","authenticated-orcid":false,"given":"Michael P.","family":"Wendel","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynecology, University of Arkansas for Medical Sciences, 4301 W.
