Abstract
Polyhydramnios is associated with many serious maternal complications such as placental
abruption or cord prolapse at rupture of membranes, uterine dysfunction at delivery,
and postpartum hemorrhage. When considering uterine dysfunction caused by overstretched
uterine muscles, active artificial amniotomy for more efficient labor seems to be
a preferred obstetric management, but the potential adverse complications make obstetricians
hesitate to perform this procedure. In such a challenging situation, a new strategy
is required. We recently performed pinhole artificial amniotomy using an amnioscope
in four women with polyhydramnios, not only to accelerate of labor but also to more
slowly and safely reduce amniotic fluid volume. We had no complications using this
procedure, and all women were able to have a vaginal delivery without postpartum hemorrhage
and neonatal asphyxia. Pinhole artificial amniotomy using an amnioscope may be more
convenient and safer than conventional artificial amniotomy. The significance of the
amnioscope has been practically nil in modern obstetric management. In this pilot
clinical study, we identified a new value for the amnioscope as a promising device
for safer amniotomy in women with polyhydramnios.
