Abstract:
The paper reports the myocaraial protection in 590 cases having undergone open heart surgery with CPB. The following methods were administered for heart preserving: Lowering the blood temperature to 24～27℃ under CPB; perfusing coronary arteries with cardioplegic solution(high potassium at 4℃) every half an hour; Keeping hemodilution at the middle degree(HCT: 20～25%, Hb: 80g/L); Lowering the temperature of the heart surface to 20～9℃ with snow ice. Automatic rebeating of the heart was in 413(68%) cases and defibrillative rebeating in 177(32%). Th method was characterized by complete hypo-temperature of the heart, decreaseing oxygen consumption and micro-thrombus etc. And therefore it made the automatic rebeating rate higher.
