Brief Summary:
Mothers are given the medication oxytocin after birth to help the uterus (womb) contract and therefore reduce blood loss. In Canada, oxytocin is given either into the muscle of the thigh or into a vein. However, it is not known which route is better.This study will test which dose and route of oxytocin is best in reducing blood loss following vaginal delivery.
