摘要:

目的探讨保持有效灌注压前提下实施控制性低中心静脉压(LCVP)对脊柱侧弯矫形术中出血量的影响。方法 60例ASAⅠ或Ⅱ级脊柱侧弯行矫形手术患者随机均分为控制性LCVP组(L组)和对照组(N组)。两组均选择静-吸复合全麻,术中常规监测切皮前、切皮后30min、1、2、4h和术毕时的HR、MAP、CVP和SpO2。L组术中限制输液并辅以微量泵静脉注入硝酸甘油,控制CVP0~5cmH2O;N组术中维持CVP6~12cmH2O。两组均根据出血情况调整输液速度,出血量达血容量25%、测定Hb低于70g/L时输注红细胞悬液。记录两组患者术中出血量、输液量和输血量。结果两组不同时点HR、MAP组间组内差异无统计学意义。L组患者术中出血量、输液量和输血量明显少于N组(P   and normal central venous pressure group(group N, n一30)。八Il the patients received generalanesthesia, routinely monitoring HR, MAP, CVP, EC.G, SpO_.
