摘要
目的探讨中分子羟乙基淀粉(中分子羟乙基淀粉)对外科手术后脓毒性休克患者血流动力学和组织灌注的影响。方法对20例脓毒性休克患者用中分子羟乙基淀粉进行液体复苏治疗,分别于复苏前、复苏达标后测定血流动力学指标、血乳酸浓度、胃黏膜二氧化碳分压与动脉血二氧化碳分压的差值(Pg-aCO2)、氧输送(DO2)和氧消耗(VO2)。结果复苏达标后心脏指数(cardiac index,CI)从复苏前的(4.4±1.0)L·min^-1·m^-2上升至(5.9±1.4)L·min^-1·m^-2(P〈0.01);左心室每搏工作指数(left ventricular stroke work index,LVSWI)从复苏前的(37±12)J/m^-2上升至(51±14)J/m^-2(P〈0.01);体循环血管阻力指数(systemic vascular resistance index,SVRI)从复苏前的(1069±408)kPa·s·L^-1·m^-2上升至(1384±485)kPa·s·L^-1·m^-2(P〈0.01);血乳酸浓度从复苏前的(8±3)mmol/L下降至(6±4)mmol/L(P〈0.01);Pg-aCO2从复苏前的(16±7)mmHg下降至(12±6)mm Hg(P〈0.01);DO2从复苏前的(586±185)ml·min^-1·m^-2上升至(802±204)ml·min^-1·m^-2(P〈0.01),VO2变化不明显。结论中分子羟乙基淀粉可以改善脓毒性休克患者的血流动力学指标和组织灌注。
Objective To investigate the effects of hydroxyethyl starch on hemodynamics and tissue perfusion in patients with septic shock. Methods Twenty septic shock patients were treated with hydroxyethyl starch for fluid resuscitation, the hemodynamic values, blood lactate concentration, Pg-aCO2 , DO2 ,VO2 before and after successful resuscitation were measured respectively. Results CI increased from (4.4±1.0) L·min^-1·m^-2 to (5.9 ±1.4) L ·min^-1·m^-2(P〈0.01); LVSWI increased from ( 37 ± 12) J/m^2 to (51 ± 14) J/m^2 ( P 〈 0. 01 ) ; SVRI increased from ( 1069± 408 ) kPa·s·L^-1·m^-2 to ( 1384± 485 ) kPa ·s·L^-1·m^-2 ( p 〈 0. 01 ) ; Blood lactate concentration decreased from ( 8 ± 3 ) mmol/L to (6 ±4) mmol/L(P 〈0. 01 ) ; Pg-aCO2 decreased from ( 16 ±7) mm Hg to ( 12 ±6) mm Hg(P 〈0. 01 ) ; andDO2 increased from (586±185) ml ·min^-1·m^-2 to (802±204) ml ·min^-1·m^-2(P〈0.01). During the period VO2 experienced no changes. Conclusions Hydroxyethyl starch( 130/0. 4) can improve hemodynamics and tissue perfusion in patients with septic shock.
