The Fusion Versus The Affinity Oxygenation Systems
- Conditions
- Complication of Coronary Artery Bypass Graft
- Interventions
- Device: fusion oxygenation systemDevice: Affinity oxygenation system
- Registration Number
- NCT02554305
- Lead Sponsor
- Hadassah Medical Organization
- Brief Summary
This study compares between the clinical, hematological, inflammatory and neurological outcome of patients undergoing Coronary Artery Bypass Grafting (CABG) surgery in which different oxygenation systems will be used.
- Detailed Description
In order to assess the efficacy and safety of fusion Oxygenation System in patients undergoing isolated CABG, a prospective one-to-one randomized trial comparing the fusion oxygenation to the currently used affinity oxygenation system will be conducted. Forty patients intending to undergo CABG will be divided into 2 groups according to the oxygenation system which will be used during surgery. Distribution into groups will be done randomly. Ten patients undergoing elective peripheral vascular surgical procedures under general anesthesia and 10 patients undergoing elective percutaneous coronary intervention will serve as control groups for the neurological outcomes. Clinical status, inflammatory and hematological response as well as Neurological outcome will be assessed.

- Primary Outcome Measures
Name Time Method major adverse events Participants will be followed for 30 days following the surgery Number of major adverse events (including mortality) will be assessed
- Secondary Outcome Measures
Name Time Method Neurological outcomes- electroencephalogram (EEG) Participants will be followed 3 days following the surgery. Changes in brain activity pattern before and after the surgery will be assessed and compared between the study groups.
Number of participants with abnormal laboratory values Participants will be followed for 3 days following the surgery. Hemoglobin and hematocrit, Platelet number and activation and Thrombin activation will be measured. Within each group, the change overtime will be compared to baseline. Participants' number with abnormal laboratory values in each study group will be assessed and compared with the other groups.
Neurological outcomes-Functional magnetic resonance imaging (MRI) Changes in brain activity pattern will be assessed at baseline and 4 weeks postoperatively . Changes in brain structure and patterns of neural activation in response to cognitive tasks will be assessed using structural and functional MRI and compared between the study groups.
Neurological outcomes-Transcranial Doppler (TCD) Participants will be followed 3 days following the surgery. Changes in brain activity pattern before and after the surgery will be assessed and compared between the study groups.
Systemic inflammatory response Participants will be followed 3 days following the surgery. Serum markers of inflammation will be measured at 4 time points: after induction of anesthesia, immediately after termination of cardiopulmonary bypass, 3 hours, and 3 days postoperatively. : heparinized arterial (intraoperatively) or venous (postoperatively) blood samples will be collected. Bio-assay of endothelial permeability will be also done. Within each group, the change overtime will be compared to baseline. Participants' number with abnormal laboratory values in each study group will be assessed and compared with the other groups.
