NCT01072747 | Unknown Phase 3

• 1 other identifier: HEPSBCCV1109BOV_BER
• Study Type: interventional
• Target: 104
• Locations: 1 country
• Sites: 1

Brief Summary

The primary objective of this study is to verify, through a randomized, blinded, parallel clinical trial, the efficacy of bovine heparin from Bergamo Laboratory ACTIPARIN ® product when compared to porcine heparin APP Pharmaceutical in patients undergoing surgery cardiovascular disease and who require cardiopulmonary bypass, through the control of hemostasis during and after surgery, based on measurements of markers of coagulation ACT, aPTT, anti-Xa heparin levels and the excessive blood loss (hemorrhage) after the end of surgery.

Conditions

Prevention of Venous Thromboembolism

Outcome Measures

Primary Outcomes (1)

• Coagulometric parameters markers heparin activity: ACT, APTT and Anti - Xa

  (T0) Pre heparintion; (T1) Top of extracorporeal; (T2) Intraoperative period; (T3) End bypass; (T4) Postoperative

Secondary Outcomes (1)

• Value of the total dose of heparin used, the activity and adequate reversal with the use of protamine.

  (T0) Pre heparintion; (T1) Top of extracorporeal; (T2) Intraoperative period; (T3) End bypass; (T4) Postoperative
