The study will evaluate whether prophylactic oxytocin administered in the third stage of labor via IV infusion results in a lower mean blood loss compared to IM injection.

The study will compare the effect of IV infusion and IM oxytocin administration on the proportion of women who experience blood loss greater than or equal t 350 ml, the proportion of women who experience blood loss greater than or equal to 500 ml, side effects, adverse events and change in hemoglobin pre- to post-delivery. It will also assess whether a bleeding history questionnaire can identify women at risk for excessive bleeding and help to define the distribution of bleeding scores among women with and without excessive bleeding.
