Conditions

Postpartum Hemorrhage

Brief summary

The purpose of this study is to decrease the likelihood of composite postpartum hemorrhage (PPH) morbidity, which consists of i) Estimated or quantified blood loss of 1,500 mL or more, ii) transfusion of any blood products or iii) hysterectomy

Interventions

COMBINATION_PRODUCTSaline delivered using an intrauterine pressure catheter (IUPC)

An intrauterine pressure catheter (IUPC) will be placed in participants after membrane rupture, or at 4 cm if membranes previously ruptured. A 300cc bolus of normal saline will be administered. A continuous rate of 100 cc/hr of normal saline will continue until delivery to prevent Postpartum Hemorrhage. If the IUPC is dislodged, it will be replaced by a trained clinician.
