摘  要:目的:评价连续性静脉-静脉血液滤过(CVVH)对经肺热稀释测量参数的影响。方法采用前瞻性观察性研究方法。选择2012年7月至2014年7月天津市第三中心医院重症医学科收治的需要同时进行CVVH和血流动力学监测的56例患者为研究对象。所有患者经股静脉置入血滤导管,同时使用脉搏指示连续心排血量(PiCCO)监测技术进行经肺热稀释测量。分别于CVVH前、即刻和30 min 3个时间点测定患者的平均动脉压(MAP)、中心血温、心排血指数(CI)、全心舒张期末容积指数(GEDVI)、胸腔内血容量指数(ITBVI)和血管外肺水指数(EVLWI)。结果56例患者中男性36例,女性20例;年龄(66±16)岁;身高(172±6)cm;体质量(68±10)kg;急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ)评分(26±6)分。CVVH开始后中心血温逐渐下降,CVVH 30 min时明显低于开始前(℃:37.17±1.06比37.57±1.26,P<0.01)。CVVH开始前后各时间点MAP、 EVLWI均无明显改变,MAP分别为(89±20)、(86±16)、(90±17)mmHg(1 mmHg=0.133 kPa);EVLWI分别为(9.4±3.2)、(9.3±3.0)、(9.4±2.9)mL/kg。CVVH开始后CI、 GEDVI、 ITBVI均呈逐渐下降趋势;与CVVH前比较, CVVH即刻CI、 GEDVI、 ITBVI下降差异均无统计学意义〔CI(mL·s-1·m-2):62.18±24.34比63.85±21.84,GEDVI(mL/m2):705±103比727±100,ITBVI(mL/m2):881±129比908±125,均P>0.05〕;而CVVH开始30 min时CI、 GEDVI、 ITBVI均显著下降,差异有统计学意义〔CI(mL·s-1·m-2):57.84±20.50比63.85±21.84,GEDVI(mL/m2):681±106比727±100,ITBVI(mL/m2):851±133比908±125,均P<0.05〕。CVVH 30 min时,CI较CVVH前下降了6.01 mL·s-1·m-2〔95%可信区间(95%CI)=-10.67~-1.50, P=0.011〕,GEDVI下降了46 mL/m2(95%CI=-81~11,P=0.014),ITBVI下降了57 mL/m2(95%CI=-101~-13, P=0.014)。结论 CVVH即刻对经�ObjectiveTo evaluate the influence of continuous venovenous hemofiltration (CVVH) on measurement of transpulmonary thermodilution parameters.MethodsA prospective observational study was conducted. Fifty-six patients who received CVVH and hemodynamic monitoring at the same time admitted to the Department of Critical Care Medicine of Tianjin Third Central Hospital from July 2012 to July 2014 were enrolled. In all the patients, the dialysis catheter was inserted through the femoral vein, and transpulmonary thermodilution measurements were performed by pulse indicator continuous cardiac output (PiCCO) monitoring technology at the same time. Mean arterial pressure (MAP), central blood temperature, cardiac index (CI), global end-diastolic volume index (GEDVI), intrathoracic blood volume index (ITBVI) and extravascular lung water index (EVLWI) were measured before CVVH, immediately after CVVH, and 30 minutes after CVVH, respectively.Results In the 56 patients, there were 36 males and 20 females, (66±16) years of old, height of (172±6) cm, body weight of (68±10) kg. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores was 26±6. After CVVH,the central blood temperature was gradually decreased, and blood temperature at 30 minutes after CVVH was significantly lower than that before CVVH (℃: 37.17±1.06 vs. 37.57±1.26,P〈 0.01). There were no significant changes in MAP and EVLWI before and after CVVH, the MAP was (89±20), (86±16), (90±17) mmHg (1 mmHg = 0.133 kPa) at three time points respectively, and EVLWI was (9.4±3.2), (9.3±3.0), (9.4±2.9) mL/kg, respectively. After CVVH, CI, GEDVI and ITBVI showed a gradual downward tendency. Compared with those before CVVH, the decline of CI, GEDVI, and ITBVI immediately after CVVH was not statistically significant [CI (mL·s-1·m-2): 62.18±24.34 vs. 63.85±21.84, GEDVI (mL/m2): 705±103 vs. 727±100, ITBVI (mL/m2): 881±129 vs. 908±125, allP〉
