Fetal activity in premature rupture of membranes.

Fetal movement (FM) counts by mothers with premature rupture of membranes (PROM) may be helpful in estimating fetal well being, provided FM assessment is not altered by the reduced amniotic fluid. It is possible that the decreased uterine volume restricts fetal movements, though the closer contact of the fetus to the uterine wall may enhance maternal perception of even weak FM. The present study compared maternally perceived FM in 41 cases of PROM to 120 uncomplicated pregnancies. No significant differences in FM counts were detected between the two groups at any of the gestational ages. Fetal movement counts by mothers with PROM, therefore, can assist fetal surveillance as is the case in pregnancies with intact membranes.
