  Purpose

Cardiac surgery leeds to a systematic inflammatory response induced by the surgical trauma and the use of the cardiopulmonary bypass (CPB). Activation of inflammatory cascades can cause a systemic inflammatory response syndrome (SIRS) which is associated with increased morbidity and mortality. Therefore, strategies to reduce the inflammatory response have a potential benefit for cardiac surgery patients.

The clinical benefit of reducing proinflammatory cytokines such as IL-6, Il-8 and TNF-a with the use of a cytokine adsorbing circuit (Cytosorb) during CBP remains unclear. Therefore, the investigators conduct this prospective, observational pilot study to determine the clinical impact of the use of a cytokine adsorbing circuit during CBP.

Study Type: Observational
Study Design: Observational Model: Case-Control
Time Perspective: Prospective
Official Title: Removal of Cytokine on Cardiopulmonary Bypass With CytoSorb® Compared to on- and Off-pump Myocardial Revascularization

Further study details as provided by Dr. Antje-Christin Deppe, University Hospital of Cologne:

Primary Outcome Measures:
  • Evolution of the inflammatory response [ Time Frame: Change from Baseline in cytokine level direct after surgery, 6 and 24 hours after surgery; 5. postoperative day ]
    Il-6; Il-8; TNF-a; C3/C4-complement Leucocytes CRP


Secondary Outcome Measures:
  • Length of ICU and hospital stay [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 10 days ]
    Length of ICU and hospital stay

  • Length of ventilation [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 10 days ]
    Length of ventilation (hours)

  • Length of catecholamine therapy [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 10 days ]
    Length of catecholamine therapy

  • kidney injury [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 10 days ]
    kidney injury defined as an increase in SCr by ≥1.0 mg/dl (≥26.5 μmol/l) after surgery ; or Increase in SCr to ≥1.5 times baseline, or Urine volume < 0.5 ml/kg/h for 6 hours.

  • MACCE (mortality; myocardial infarction; cerebrovascular accident) [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 10 days ]
    Mortality measured as any kind of death and myocardial death Myocardial Infarction measured with ECG; CK-MB, cTnT Cerebrovascular accident verified with abnormal cerebral CT scan

Estimated Enrollment: 300
Study Start Date: August 2014
Estimated Study Completion Date: July 2018
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Groups/Cohorts
CPB + Cytosorb
On pump myocardial revascularization with the use of the cytokine adsorbing circuit (Cytosorb)
CPB / Control
Controll group; on pump myocardial revascularization
OPCAB / Control
Controll Group; off-pump myocardial revascularization

Detailed Description:
Patients, who have an elective myocardial revascularization and give there written consent will be enrolled to the study. Demographic, intraoperative, and postoperative data will be collected prospectively. Furthermore, blood samples (1. before induction of anaesthesia 2. at the end of CPB 3. 6 hours after surgery 4. 24 hours after surgery 5. 3-5 days after surgery) will be analyzed.
