Design outcomes

Primary

Measure	Time frame
The primary goal of this "hemolysis study" is to check the kidney function of patients after coronary bypass surgery with and without heart-lung machine (HLM) on the basis of special postoperative laboratory parameters (especially haptoglobilin, free Hb, but also creatinine, urea, GFR). Central goal: Is kidney function less severely impaired after bypass surgery without HLM?	—

Secondary

Measure	Time frame
Hb, leukocytes, hematocrit, platelets, K, Na, Quick, PTT, bilirubin, GOT, GPT, gamma-GT Questionnaire with assessment of quality of life (Visual analogical scale 1-10), recording of complications (morbidity, including further operations, cardiac catheterization procedures, pumping power of the heart), mortality	—
