An improved method of topical cardiac hypothermia
LI Bonchek and GN Olinger
Current methods of myocardial protection usually employ together with
topical hypothermia by pericardial lavage. Pericardial lavage is
inconvenient, inconsistent, and noisy: it wastes blood: it cannot cool the
right ventricle effectively. We use a new myocardial protection jacket to
cool the heart during operation other than simple coronary bypass
procedures. Myocardial temperatures are maintained at 7 degrees to 14
degrees C indefinitely without reinfusion of cardioplegia solution. The
jacket is a more convenient and much more effective method of obtaining
profound topical hypothermia.
