Trial Outcomes & Findings for Study Of Tranexamic Acid For The Reduction Of Blood Loss In Patients Undergoing Major Abdominal Surgery (NCT NCT00827931)

Last Updated: 2012-04-26

Results Overview

Post-operative blood loss was defined as the sum of the drainage volumes measured over post-operative days 1, 2, and at drain removal. It was measured by weighing the drapes/ dressings or swabs prior to soaking to measure difference in weight and checking drain collectors until drains were removed.
