개심술시 대동맥차단후 반복투여되는 $

다국어 초록 (Multilingual Abstract)

In cardiac patients who received multidose cold blood potassium cardioplegia for intracardiac procedures, the intraoperative and the immediate postoperative blood potassium levels were decreased at aortic cross-clamp time below 2 hours and increased at aortic cross-clamp time above 2 hours, but they were within normal limit [not hypokalemia or hyperkalemia]. In spite of increased infusion numbers and amount of cold blood potassium cardioplegia, the postoperative blood potassium levels were similar to the postoperative levels, the immediate postoperative A-V blocks were transient and the postoperative arrhythmia were rare.
