Administering cold cardioplegia in patients undergoing coronary artery bypass grafting
BP Mindich, RA Jurado, MR Estioko and RS Litwak
In patients undergoing coronary artery bypass grafting (CABG), use of
hypothermic cardioplegia for myocardial protection may not always achieve
even cooling in the areas distal to a severely obstructed artery. Employing
simultaneous myocardial temperature measurements, we documented "warm"
areas in some patients having CABG. We then devised a technique of combined
aortic root and intracoronary cardioplegic infusion. This has achieved
prompt cooling of the warm areas and has resulted in uniform myocardial
temperatures of 5 degrees to 8 degrees C.
