摘 要:目的 研究全麻诱导期急性超容量液体填充(acute hypervolemic fluid infusion, AHFI)对冠状动脉粥样硬化性心脏病患者行非体外循环冠脉旁路移植术(off-pump coronary artery bypass grafting, OPCABG)血液动力学的影响。方法 40例患者按随机数字表法随机分为6%羟乙基淀粉130/0.4(6% hydroxyethyl starch 130/0.4, HES 130/0.4)组和乳酸林格液(lactated ringer's solution, RL)组,每组20例。 全麻诱导前5 min开始, 30 min内分别输注HES 130/0.4或RL10 ml/kg。在麻醉诱导前5 min(T0),诱导后即刻(T1),插管后即刻(T2),插管后5 min(T3)及AHFI结束后(T4)分别记录心率(HR),血压(BP),中心静脉压(central venous pressure, CVP),心脏指数(cardiac index, CI),每搏输出量(stroke volume, SV)及每搏变异指数(stroke volume variation, SVV)。 结果 与T0时HR[(66.2±9.5) 次/min、平均动脉压(mean arterial pressure, MAP)[(98.6±12.5)mm Hg(1 mm Hg = 0.133 kPa)]、CI[(2.7±0.4) L?min-1?m-2]、SV[(82.5±17.4) ml]及SVV[(8.6±4.3)%比,HES130/0.4组患者T1时MAP[(82.3±10.8) mm Hg]、CI[(2.3±0.3) L?min-1?m-2]及SV[(73.4±15.5) ml]均下降;在T3和T4时HR[(57.8±6.2)次/min和(56.4±6.9) 次/min]下降;T4时CI[(3.2±0.4) L?min-1?m-2]升高,但是SVV[(6.3±3.2)%]降低(P 〈 0.05);而RL对照组在T1、T3及T4时MAP[(78.8±12.1)、(82.7±12.9) 及(79.2±10.1) mm Hg]和SV[(71.3±16.2)、(73.6±15.9)及(74.4±16.3) ml]均降低(P 〈 0.05或P 〈 0.01)。在T3时与RL对照组CI[(2.5±0.4) L?min-1?m-2]和SV[(73.6±15.9) ml]比,HES130/0.4组CI[(3.0±0.5) L?min-1?m-2]和SV[(91.2±18.6 ) ml]均升高(P 〈 0.05)。在T4时与RL对照组MAP[(79.2 ± 10.1) mm Hg]、CI[(2.6±0.4) L?min-1?m-2]、SV[(74.4±16.3) ml]和SVV[(10.6±4.5) %)]比较,HES130/0.4组MAP[(88.2±9.4) mm Hg]、CI[(3.2±0.4) L�Objective To investigate the effects on hemodynamic efficacy of acute hypervolemic fluid infusion (AHFI) during induction of general anesthesia in patients undergoing off-pump coronary artery bypass surgery. Methods Five minutes before induction of general anesthesia, forty patients undergoing off-pump coronary artery bypass surgery were randomized to receive 10 ml/kg of low-molecular 6% hydroxyethyl starch 130/0.4 (HES 130/0.4 group, n = 20) or lactated ringer’s solution (RL group, n= 20), within 30 min. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), central venous pressure (CVP), cardiac index (CI), stroke volume (SV), and stroke volume variation (SVV) were recorded 5 min before induction of anesthesia (T0, baseline), immediately after anesthetic induction (T1), immediately after intubation (T2), 5 min after intubation (T3), and after the end of AHFI (T4). Results Compared with T0, MAP, CI and SV were significantly decreased at T1 [from (98.6 ± 12.5) mm Hg(1 mm Hg = 0.133 kPa), (2.7 ± 0.4) L?min-1?m-2, and (82.5 ± 17.4) ml to (82.3 ± 10.8) mm Hg, (2.3 ± 0.3) L?min-1?m-2 and (73.4 ± 15.5) ml, respectively. (P 〈 0.05)], HR was significantly decreased at T3 and T4 [from (66.2 ± 9.5) bpm to (57.8 ± 6.2) bpm and (56.4 ± 6.9) bpm, respectively), CI was significantly decreased at T4 [from (2.3 ± 0.3) L?min-1?m-2 to (3.2 ± 0.4) L?min-1?m-2], but SVV was significantly increased at T4[from (8.6 ± 4.3) % to (6.3 ± 3.2) %] in HES140/0.4 groups. However, MAP and SV were significantly decreased at T1 [(78.8 ± 12.1) mm Hg and(71.3 ± 16.2)ml], T3 [ (82.7 ± 12.9) mm Hg and (73.6 ± 15.9) ml], and T4 [(79.2 ± 10.1) mm Hg and (74.4 ± 16.3) ml] in RL group (P 〈 0.05, or P 〈 0.01). Compared with RL group, CI and SV were significantly increased at T3 [from (2.5±0.4) L?min
