Amniotic Fluid Volume and Composition in Mouse Pregnancy
Journal of the Society for Gynecologic Investigation, 2005The current study was undertaken to determine simultaneous changes in amniotic fluid (AF) volume and composition across gestation in the pregnant mouse.Young adult mice (6 to 7 weeks old) of the CB6F1 strain were mated overnight. AF was collected on consecutive days from embryonic days 9.5 through 18.5 for measurements of volume and composition ...

Assessment of Amniotic Fluid Volume in Pregnancy
RadioGraphics, 2023Amniotic fluid (AF) is an integral part of the fetal environment and is essential for fetal growth and development. Pathways of AF recirculation include the fetal lungs, swallowing, absorption through the fetal gastrointestinal tract, excretion through fetal urine production, and movement.

Amniotic Fluid Index: Correlation with Amniotic Fluid Volume
American Journal of Perinatology, 1992We calculated the amniotic fluid indexes (AFIs) of 310 women on 459 occasions. Normative data were analyzed and compared with data in several high-risk groups. In the normal gestations there was a progressive increase in AFI with advancing gestation until 32 weeks, after which there was a decline.

Measurement of amniotic fluid volume
Vrach, 2023The qualitative or semi-quantitative assessment of amniotic fluid volume (AFV) is a standard component of every ultrasound in the second and third trimesters of pregnancy. AFV abnormalities are associated with various pregnancy complications. In clinical practice, ultrasound (US) assessment of AFV is used in conjunction with other clinical and ...

Amniotic fluid volumes in normal pregnancies
American Journal of Obstetrics and Gynecology, 1972Abstract One hundred and eighty-seven amniotic fluid determinations were performed on 115 patients from 15 to 42 weeks' gestation by the para-aminohippurate method of Charles and Jacoby. Our results show a wide normal range which increases as pregnancy progresses. The significant variations in individual trends are shown.

SUMMARYThe various ways of estimating amniotic fluid volumes during pregnancy are all based on dilution techniques involving the use of dyes, radioactive isotopes, or such inert substances as inulin or sodium aminohippurate. Much work still needs to be done to show the limits of normality of the quantity of amniotic fluid at various stages of pregnancy.

Amniotic Fluid Volume in Spurious Labour
Journal of Obstetrics and Gynaecology Research, 1997AbstractObjective: A prospective study was undertaken to assess the amniotic fluid index (AFI) in women with spurious labour and its possible role in management.Methods: Eight hundred and ninety‐three women in early labour, who had uncomplicated pregnancy, were recruited for the study.

Amniotic Fluid and the Clinical Relevance of the Sonographically Estimated Amniotic Fluid Volume
Journal of Ultrasound in Medicine, 2011The amniotic fluid volume (AFV) is regulated by several systems, including the in-tramembranous pathway, fetal production (fetal urine and lung fluid) and uptake (fetal swallowing), and the balance of fluid movement via osmotic gradients. The normal AFV across gestation has not been clearly defined; consequently, abnormal volumes are also poorly ...

Abstract After a brief introduction concerning the physiology of amniotic fluid circulation, the different methods of volume estimation (eyeballing, maximum vertical depth, amniotic fluid index) are discussed. We conclude with the work-up in cases of oligo- and polyhydramnios.

Effect of Maternal Hydration on Amniotic Fluid Volume
Obstetrics & Gynecology, 2003To estimate the effects of maternal intravenous hydration on amniotic fluid volume in normal pregnancies.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 ...
