Carbetocin Versus Oxytocin Infusion Plus Tranexamic Acid During Cesarean Section

Registration Number
NCT03777878
Lead Sponsor
Aswan University Hospital
Brief Summary

Purpose to evaluates the effects of oxytocin infusion with or without intravenous tranexamic acid (TA) in comparison with Carbetocin for prevention of postpartum hemorrhage at a cesarean section with one or more risk factor for postpartum hemorrhage.

Detailed Description

Postpartum hemorrhage (PPH) is potentially life-threatening and is a significant contributor to maternal mortality and morbidity especially in developing countries. The risk of PPH is much higher for women undergoing cesarean delivery (CD). Oxytocin is regarded as the gold standard uterotonic agent but only has a half-life of 4-10 min; therefore, at cesarean section oxytocin must be administered as a continuous intravenous infusion to attain sustained uterotonic activity throughout the surgical procedure and immediate postpartum period. Carbetocin is a long-acting synthetic analog of oxytocin that can be administered as a single-dose injection; intravenously administered carbetocin has a half-life of approximately 40 min.

A single intravenous bolus of carbetocin produces a tetanic uterine contraction within 2 min and persists for an average of 60 min following injection.

The aim of this study is to compare the effectiveness of combined tranexamic acid (TA) and oxytocin infusion with intravenous carbetocin for prevention of PPH in patients with risk factors during cesarean section.
