Question

Answer in at least 150 words:

May, pregnant for the first time, has been in the delivery room for several hours. Test indicated the fetus had its head down. She was ten days overdue so the obstetrician scheduled an induced delivery and injected her with oxytocin. Neither contractions nor pain have resulted. The physician then attempted a "drip" of OT and prostaglandin suppository with no success. The doctor even tried using different lot numbers and manufacturing dates of the hormones. Clearly, OT was making no difference! Keeping in mind that it is dangerous to allow the fetus to stay in the uterus much longer and based on ghe information in this chapter, provide a reason for the failure of the uterus to contract and a possible solution.

Answer 1

here the pregnant lady's over date and no spontaneous uterine contraction occured and even after giving injection oxytocin and suppository prostaglandin. oxytocin is a hormone produced in hypothalamus . oxytocin binds with its receptor present in uterine endometrium and myometrium and increases intracellulr calcium and increases smooth muscle conntraction . here the uterine underone atony , so that it will be in relaxed manner ad not pushing fetus outside uterus. the receptor of oxytocin may be oversaturated and that leads to failure of contraction even after iv injection of oxytocin. if she uses tocolytic agents like beta agonist drugs , magnesium sulphate , oxytocin antagonists , calcium chanel blockers , adrenal receptors antagonists., pain kilers  .. these cause failure of uterine contraction

the managment option for this primigravida is emergency cesarean delivery .
