Trial Outcomes & Findings for Tranexamic Acid and Thromboelastography During Cesarean Delivery (NCT NCT02026297)

NCT ID: NCT02026297

Last Updated: 2020-10-27

Results Overview

Blood samples will be collected for evaluation one our after initiation of the study infusion. Whole blood samples are tested in a point-of-care thromboelastography machine and R time, or time to initiation of clot formation, is measured in minutes.

PRIMARY outcome

Timeframe: 6 weeks postpartum

Population: postpartum Obstetrician evaluation at 6 weeks: obstetric bleeding requiring surgical intervention, blood transfusion, or both; thrombotic complications including: venous thrombus seen on ultrasound, thromboembolic event

The electronic patient record from each patients' 6-week postpartum visit will be reviewed for the following: * delayed bleeding complications, defined as obstetric bleeding requiring surgical intervention, blood transfusion, or both. * thrombotic complications including: venous thrombus seen on ultrasound, thromboembolic event
