Zusammenfassung:The rate of passage of water and sodium from the maternal circulation to the amniotic fluid has been measured with heavy water and radioactive sodium as the tracer substances. The water of the fluid is completely replaced on the average once every 2.9 hours; this considerable rate of turnover is at variance with the concept that the amniotic fluid is stagnant. The rate of transfer of water is about five times more rapid than that of sodium.
