Efficacy and Safety of Sodium Heparin in Patients

Study Overview
=================
Brief Summary
-----------------
The objective of this study is verify, through a randomized, single-blind, multicentre, parallel and comparative study, the effectiveness of heparin sodium of porcine origin in patients undergoing heart surgery at that require the aid of cardiopulmonary bypass, through the control of hemostasis during and after surgery, based on the strengths of markers of coagulation TCA, TTPA, Anti-Xa, heparin bioavailable and loss of excessive blood (bleeding) at the end of the surgery.
