About this study
Official title: The Comparison of the Effect of Different Oxytocin Administrations on the Blood Loss During Cesarean Delivery: a Randomised Controlled Trial
This study compares the effect of starting intravenous oxytocin infusion early before uterine incision versus late after umbilical cord clamping on the blood loss during elective cesarean section
Read the detailed description
Postpartum hemorrhage (PPH) is still the major cause of maternal morbidity and mortality worldwide contributing to nearly 25% of direct maternal deaths. The average blood loss during cesarean section is 1000 ml which is nearly double the blood loss during vaginal delivery. Worldwide, the most commonly used uterotonic for the prevention of PPH is oxytocin. Several regimens of oxytocin have been tested during cesarean section with variable wanted (uterotonic) and unwanted (cardiovascular) effects. In the current study, we tested the hypothesis that initiating IV oxytocin infusion earlier before uterine incision would induce a rapid acceptable uterine contraction and minimize the intraoperative blood loss than the same dose administered after delivery of the fetus.

| Study group | Role | What they receive |
|---|---|---|
| before uterine incision oxytocin group | Experimental | IV infusion of 20 IU of oxytocin started before uterine incision Receives: Other: before uterine incision oxytocin |
| after clamping the umbilical cord oxytocin group | Active comparator | IV infusion of 20 IU of oxytocin started immediately after clamping the umbilical cord Receives: Other: after clamping the umbilical cord oxytocin |
What is being measured
The primary outcome is the main question the study is designed to answer.
blood loss during elective cesarean section
The intraoperative blood loss will be measured by adding the volume of the suction bottle with the blood soaked sponges (know dry weight). The blood loss was estimated after excluded amniotic fluid volume in the suction bottle in each case
Measured: 2 hours
Secondary outcomes (1)
postoperative blood loss
The hemoglobin and hematocrit values will be measured 24 hours after CS
Measured: 24 hours
