Decreased fetal movements has nothing to do with Injection Betnesol
Betnesol is given to enhance the lung maturity of the babies, as preterm labour might be suspected.
Decreased movements of babies could be due to hypoxia, maternal dehydration
or disease, decreased amniotic fluid
, cord entanglement or any in utero stress to the babies.
You should consult your obstetrician as this is a precious pregnancy
for you, consult immediately and let her reassess the babies.
