摘要 目的验证二氧化碳改良型术野充弥法在体外循环(CPB)中消除微气栓的效果。方法 60例CPB手术病例随机分A组(二氧化碳改良型术野充弥法),B组(Svenarud设计的CO2弥散头)和C组(不用CO2术野充弥)各20例。病例均以经颅多普勒超声(TCD)微气栓检测系统检测大脑中动脉中动脉血流微栓子信号,在CPB期间分五个时段分别记录和计算血流中微气栓数目。结果主动脉开放后5 min时间段内,C组微气栓数目〔(43.5±2.95)个/min〕显著多于A组〔(15.2±1.26)个/min〕和B组〔(13.8±1.21)个/min〕(P=0.000)。A与B组差异不差异(t=1.17,P=0.349)。结论二氧化碳改良型术野充弥器与Svenand等人设计CO2弥散器效果近似,可显著减少CPB手术中微气栓数目。
