Myocardial Protection With Multiport Antegrade Cold Blood Cardioplegia and Continuous Controlled Warm Shot Through Vein Grafts During Proximal Ends Anastomosis in Conventional CABG
In Brief
A Phase 2 clinical trial evaluating multiport antegrade cardioplegia and Aortic root antegrade cardioplegia for Coronary Artery Bypass Surgery. Completed, enrolled 448 participants.
Detailed Summary
In spite improvements in methods of myocardial protection, peri-operative myocardial damage is still the commonest cause of early morbidity and mortality after technically successful CABG Surgery. What is the optimum method of myocardial protection is still debatable. The investigators conducted this study to see effects of multiport antegrade cold blood cardioplegia on myocardial protection, along with continuous controlled warm blood perfusion through veins graft during proximal ends anastomosis in conventional CABG surgery in patients having multi-vessel disease.
Study Details
Timeline
Interventions
Cold blood cardioplegia was used for myocardial protection and just before the removal of the aortic cross-clamp, warm blood shot (normo-kalemic) was started through multi-perfusion set attached to cardioplegia cannula in the aortic root and vein grafts.As contraction of heart started the multiport limb attached to cardioplegia cannula was off and cross clamp was removed .The warm perfusion through the vein grafts was continued at controlled pressures of about 50-70 mmHg, flow rate of 10-30ml/min/graft and temperature of 35-37 oC
only cold blood cardioplegia was used for myocardial protection without hotshot.
