<qa>  What is the effect of myometrial desensitization following pulsatileThe investigators hypothesize that the effect of myometrial desensitization following pulsatile oxytocin exposure would be lower when compared to continuous oxytocin exposure. These results will help in establishing whether myometrial contractility and sensitivity to oxytocin can be better preserved by delivery of pulsatile oxytocin, rather than continuous oxytocin for labor induction and augmentation, and thereby result in less PPH.
