Fetal Urine Production in Late Pregnancy
Objective. Hourly fetal urine production rate (HFUPR) was studied in relation to both gestational age and the onset of spontaneous labor in normal term human pregnancies. Methods. Serial volume measurements were obtained from longitudinal ultrasound images of the fetal bladder at 1-5-minute intervals, and HFUPR was subsequently calculated. A total of 178 adequate bladder-filling cycles were rec...
متن کاملRenal Function and Urine Production in the Compromised Fetus
Fetal urine production begins in the first trimester. Autopsy findings of filled urinary bladders in human fetuses have been reported from 11 gestational weeks (Abramovich, 1968). In 1970, the first report on ultrasound investigations of the fetal urinary bladder was published (Garrett et al., 1970). Three years later, a method for estimating fetal urine production was introduced (Campbell et a...
متن کاملFetal blood volume responses to acute fetal hemorrhage.
The purpose of this study was to explore the changes in fetal blood volume that occur after fetal hemorrhage. Fifteen unanesthetized, chronically catheterized fetal sheep averaging 130 +/- 3 (SD) days gestation were studied 4 to 6 (average 5) days after catheter implantation. The fetuses were hemorrhaged by continuous withdrawal from an arterial catheter over 5 minutes. On the average (n = 15),...
متن کاملErrors in estimating lung liquid volume in fetal lambs when using radiolabeled serum albumin and blue dextran.
Fetal lung liquid volume is usually determined by using radio-iodinated serum albumin (RISA) or blue dextran (BD) as volume tracers. We tested the reliability of both tracers at 124 (G124) and 142 days of gestation (G142; term = G147) when the labels were employed simultaneously. We measured the proportion of label bound reversibly to the lung, or apparently lost from the lung compartment, by w...
