摘要
目的分析心脏直视手术体外循环前并行阶段心室颤动(室颤)的可能原因。方法回顾既往5年病例,按病种、病情、施行手术等进行总结。结果1256例中前并行阶段发生室颤5例(3.98‰),先天性心脏病发生率3.88‰,风湿性心脏病2.06‰,冠心病7.84‰,各病种间无统计学差异(P>0.05)。结论血压骤降、心功能低下、酸中毒、高钾血症及低温是前并行阶段发生室颤的主要原因,应采取相应措施,提高体外循环管理水平,降低室颤的发生率。
OBJECTIVE To analyze the risk factors of ventricular fibrillation （VF） during pre - parallel bypass. METHODS Medical records of 1256 open heart surgeries over the past 5 years in our hospital were studied retrospectively according to preoperative characteristics and operations. RESULTS 5 （3.98%0） cases experienced VF during pre - parallel bypass. Significant difference was not found among congenital heart diseases （ 3.88‰）, rheumatic heart diseases （2.06‰） and coronary heart diseases （7.84‰）. CONCLUSION Hypotension, cardiac insufficiency, metabolic acidosis, hyperkalemia and hypothermia are the major inducements to VF. Myocardium protection during cardiopulmonary bypass influences the prognosis following VF.
