【摘要】 目的:回顾性总结重症心脏瓣膜病置换术体外循环经验。方法:105例重症心脏瓣膜病患者,使用stockerⅢ型心肺机及膜式氧合器,体外循环中采用中度低温,预充白蛋白并附加人工肾超滤,心肌保护用高钾含血停搏液灌注。结果:105例患者均顺利脱机,无1例死亡。体外循环时间60～180min,主动脉阻断时间60～120min,所有患者均顺利脱离体外循环,心脏自动复跳86例,电击19例。结论:手术中加强心肌保护,可减低手术后的功能衰竭和并发症,并可有效提高手术成功率。更多还原

【Abstract】 Objective To retrospectively summarize the CPB management experience of realacement severe heart valvular disease. Methods All of the 105cases used strockerIII heart-lung machine and film oxygen machine and adopted moderate blood dilution. Results CPB time was from 60 minutes to 180 minutes, aorta crass clamping from 60 to 120 minutes. All patients smoothly broke away from CPB Monitoring blood gas analysis and electrolytes were normal, The heart automation occured in 86 cases and heart electricity beating occured in 19 cases with no death. Conclusion Myocardial preservation , acid - base balance and electrolyte disturbance, ultrafiltration and vasodilatoin should be attempted during CPB. Myocardial preservation may reduce postoperative function and lower complication and operation success rate may be improved.更多还原
