 Characterization of the effect of pulsatile oxytocin on the desensitization of myometrium when compared to the effect of continuous oxytocin, may provide guidance for the delivery of pulsatile oxytocin for labor induction and augmentation to protect against the otherwise higher risk of PPH. Furthermore, the delivery of pulsatile oxytocin may be considered in subgroups who are already at higher risk of PPH, and require labor augmentation.
