Abstract
Methods Over a two-year period (January 2011-January 2013), 32 (3.1%) patients who underwent on-pump cardiac surgery, presented ARF in the immediate postoperative period and submitted to CVVH. Blood samples were obtained in all patients before the start of the CVVH and at least 12 hours after the continuous passage of the blood through the hemofiltration filter of the CVVH-device. All blood samples were tested with thromboelastography in order to identify alterations in the elastic properties of the blood clots induced from the application of the CVVH. The main thromboelastographic parameters recorded were: the reaction time-R, the K-time, the maximum amplitude (MA), the G-index, the Angle and the coagulation index (CI).
Highlights
The purpose of this study is to present the changes in the elastic properties of the blood clots and to signify the consequential coagulation disorders after the application of CVVH in patients submitted to on-pump cardiac surgery who presented immediate postoperatively ARF
