摘  要:目的 观测非体外循环冠脉搭桥术(OPCABG)中参附注射液对血流动力学和全身氧代谢的影响.方法 选择本院冠心病择期行OPCABG手术患者56例,美国麻醉医师协会(ASA)Ⅱ~Ⅲ级,完全随机分为参附组(SF组,29例)和生理盐水对照组(NS组,27例).SF组在手术切皮前和吻合心脏血管前各静脉注射参附注射液40 ml,NS组则分别注射等量生理盐水.用漂浮导管和动脉、混合静脉血气分析监测麻醉手术过程中麻醉诱导完成并血流动力学稳定时(T1)、锯胸骨后(T2),吻合血管前(T3),吻合前降支时(T4),吻合后降支或右冠状动脉时(T5),吻合左回旋支或对角支时(T6),血管吻合完成后心脏恢复原位置(T7),闭合胸骨前(T8)及手术结束时(T9)9个时点的血流动力学和全身氧代谢.结果 在T5和T6时点,两组的心脏指数(CI)和每搏指数(SI)均明显低于T1时点[(2.1±0.6)和(2.0±0.5)比(2.3±0.5)L·min-1· m-2,(1.7±0.6)和(1.8±0.6)比(2.1±0.5)L·min-1·m-2;(24±10)和(23±8)比(32±7)ml·beat-1· m-2,(22±9)和(22±8)比(32±9) ml·beat-1·m-2,P<0.05],其中T2和T5时点,SF组的CI略高于NS组[(2.5±0.7)比(2.1±0.6)L·min-1 ·m-2,(2.1±0.6)比(1.7 ±0.6) L·min-1 ·m-2,P<0.05].整个麻醉手术期间,SF组的心率(HR)、平均动脉压(MAP)、左室工作指数(LVWI)和右室工作指数(RVWI)均略高于NS组(P<0.05).两组的pH在手术开始后均呈降低变化,其中SF组术毕的pH明显低于NS组(P<0.05).手术期间两组的碳酸氢根离子(HCO3-)、剩余碱(BE-E)和总二氧化碳(TCO2)均下降,两组间在多个时间点差异有统计学意义(P<0.05).SF组在麻醉后时点的氧供(DO2)高于NS组,但术中两组间氧耗(vO2)、氧摄取率(O2ext)和体温(T)的变化差异无统计学意义(P<0.05).结论 ASAⅡ~Ⅲ级患者非体外循环冠脉搭�Objective To investigate the effect of Shenfu injection on hemodynamics and systemic oxygen metabolism during off-pump coronary artery bypass grafting (OPCABG).Methods Fifty-six patients with coronary heart disease undergoing selective OPCABG (ASA Ⅱ -Ⅲ )were randomly assigned to Shenfu group (SF,n=29) and normal saline control group (NS,n=27).Patients in SF group received Shenfu 40 ml via intravenous injection prior to dermal preparation and graft anastamosis,respectively.In contrast,an equivalent volume of normal saline was injected in subjects of NS group.Hemodynamics and systemic oxygen metabolism was monitored using Swan-Ganz catheter,arterial and mixed venous blood gas analysis during anesthesia and surgery at nine time points of post anesthetic induction with stable hemodynamics (T1),after stemotomy (T2),before vascular anastomosis (T3),anterior drop branch anastomosis (T4),posterior descending artery or right coronary artery anastamosis(T5),left circumflex coronary artery or diagonal branch anastamosis (T6),cardiac at original position after vascular anastomosis (T7),before sternum closur(T8)and the end of operation(T9).Results Cardiac index (CI) and stroke index (SI) were significantly lower after posterior descending artery or right coronary artery anastamosis (T5) and left circumflex coronary artery or diagonal branch anastamosis (T6) as compared with post anesthetic induction with stable hemodynamics (T1)[(2.1 ±0.6) and (2.0 ±0.5) vs (2.3±0.5) L·min-1·m-2,(1.7 ±0.6) and (1.8 ±0.6) vs (2.1±0.5) L·min-1·m-2;(24±10) and (23 ±8) vs (32±7) ml·beat-1·m-2,(22 ±9) and (22 ±8) vs (32±9) ml·beat-1·m-2,P〈0.05].As compared with NS group,CI in SF group after sternotomy (T2) or T5 was slightly higher[ (2.5 ±0.7) vs (2.1 ±0.6) L·min-1·m-2,(2.1 ±0.6) vs (1.7 ±0.6) L·min-1·m-2,P〈0.05].During the operation,HR,MAP,LVWI and RVWI in SF group were sli
