Dr. Labib Ghulmiyeh, American University of Beirut Medical Center
  Purpose
The goal of this study is to determine the best dose of a drug called oxytocin, that is usually used to stop bleeding during a delivery, when used during a cesarean delivery. It will be administered during cesarean section in order to decrease the amount blood loss. The investigators are proposing to have 3 groups of subjects each given a different safe dose of oxytocin and then to assess the effectiveness of each regimens on the amount blood lost during cesarean sections.This will let use know which is the best lowest dose needed.

Primary Outcome Measures:
  • The change in hemoglobin as a measure of blood loss. The change in hemoglobin is defined as the difference between the predelivery hemoglobin value and the postpartum value [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • The need for blood transfusion and the use of additional uterotonic agents, pad weight, pad count, estimated blood loss. [ Time Frame: 1 year ]

Estimated Enrollment: 200
Study Start Date: July 2012
Study Completion Date: February 2013
Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: oxytocin
group 1 will receive oxytocin solutions with 20U/500ml during cesarean section
Drug: Oxytocin

Pre-mixed, oxytocin solutions with either 20U/500ml, 30U/500ml or 40U/500ml of Lactated Ringer's solution will be available in the pharmacy department. The bags will be identical in appearance. Each bag will be labeled with a study identification number, from which the pharmacy could determine the administered dose. Subjects as well as the medical providers will be blinded to the assignment of the solution used.

Immediately after delivery of the infant, the study solution will be infused over 30 minutes using a continuous infusion pump (666 mU/min versus 999 mU/min versus 1332mU/min).

Other Name: Pitocin
Active Comparator: oxytocin2
group 2 will receive oxytocin solutions with 30U/500ml during cesarean section
Drug: Oxytocin

Pre-mixed, oxytocin solutions with either 20U/500ml, 30U/500ml or 40U/500ml of Lactated Ringer's solution will be available in the pharmacy department. The bags will be identical in appearance.
