We always try to postpone the delivery to 37 weeks if there is any way to control the situation with preference given to Mother> Baby.
If nothing can be done we go for termination of pregnancy by appropriate methods.
In polyhydramnios, if there is maternal distress and the pregnancy is less than 37 weeks of gestation, slow decompression by amniocentesis is performed to relieve symptoms and to allow fetal maturity. Once pregnancy reaches term (37 weeks) induction of labor is done. Thank you
