  no reperfusion
When the ischemic time is longer than 90 min, warm retrograde blood cardioplegia provides better myocardial protection than no reperfusion.
      
In this study, we aimed at evaluating left atrial functions 6 months after acute myocardial infarction in three different patient groups (thrombolytic therapy, primary percutaneous intervention, or no reperfusion strategies).
      
In the ischaemia group, the volvulus remained for 4 h (no reperfusion).
      
In contrast, in those patients receiving no reperfusion therapy, no significant difference was observed between patients receiving placebo or GIK.
      
No reperfusion studies in the in situ heart were undertaken.

为了避免心肌缺血缺氧和再灌注损害,在维持心脏的血液供应及其生理活动最低限度的内环境要求下,我们在浅低温(31~35℃)体外循环心脏跳动中二尖瓣置换术,137例风心,先心二狭二闭,或合并主动脉瓣关闭不全的患者,接受了这个手术方法的治疗。不阻断主动脉,不灌注心脏停跳液,心脏空跳慢跳每分钟40~50次,术中鼻温控制在32±1℃之间。合并主动脉瓣关闭不全者先在心脏冷停跳中置换主动脉瓣,而后在心跳中置换二尖瓣,以缩短心脏泠缺血时间,三尖瓣成形术亦在心脏跳动中施术。术后病人病情平稳,平均动脉压维持在9.5~10.5kPa(70~80mmHg)之间,多巴胺用量明显减少其使用时间明显缩短。术后无低心排综合征、急性肾功能衰竭和严重心律紊乱者,术后死于感染和凝血机能障碍4例。本组手术死亡率2.9%(4/137)。为了排出左心腔内的积气,自行设计的左心腔无层级排气装置和主动脉灌流导流装置,术后无气栓症状和体征者。

Since December 1995, 7 cases of intracardiac repairing under direct vision have bcen successfully made under the condition of hypothermia extracorporeal circulation with beating heart,aorta unblocked and cardiac arrest perfusion unfilled. The key to The operation is the application of the aorta vascular with flow-leading device and the skill of continuously removing air from the root of aorta. The operation were performed with no complication, resuting in rapid recovery.

我院从1995年12月开始应用浅低温体外循环不阻断主动脉,不灌注心肌麻痹液,在心脏跳动的情况下完成7例心内直视修科手术。本本式的关键是采用具有导流装置的主动脉供血管,以及主动脉根部持续排气的技巧。全组病例手术顺利,术后无并发症,康复快,均治愈出院。

目的:为了避免心肌缺血缺氧和再灌注损伤,我们设计了体外循环下心脏跳动中室间隔缺损修补术。方法:144例室间隔缺损(VSD)接受了该手术,术中不阻断主动脉,不灌注心脏停跳液,心脏缓慢空跳40~50次/min,鼻温控制在31~35℃之间。结果:术后病人病情稳定,无低心排综合征,无Ⅲ度房室传导阻滞(Ⅲ°AVB),无气栓,无主动脉瓣关闭不全(AI)。残余漏2例,发生率1.4%(2/144)。死亡2例,占1.4%。结论:与心脏停跳下手术相比,心脏跳动中VSD修补术简化了操作,心肌无缺血缺氧和再灌注损伤状态,对减少和预防术后低心排综合征及Ⅲ°AVB等并发症的发生有积极的临床意义
