Amniotic fluid volume changes in response to frusemide induced maternal fluid shifts.

Frusemide use in pregnancy is generally restricted to patients with cardiac decompensation. In the past, maternal administration of oral frusemide had been tried to identify non-functioning fetal kidneys by utilizing the diuretic effect of frusemide on the fetal kidneys. We report a case of primigravida with severe mitral stenosis presenting in pulmonary edema that received high dose of frusemide. This was associated with the development of transient oligohydramnios. We discuss the clinical significance of this observation and the possible explanations.
