摘 要:目的本研究旨在探讨动静脉二氧化碳分压差/氧含量差[P(v-a)CO_2/C(a-v)O_2]在预测脓毒症患者预后中的临床应用价值。方法前瞻性选取2013年1月-2015年12月收治的脓毒症患者120例。入院时收集患者复苏前(0 h)的P(v-a)CO_2/C(a-v)O_2、C(a-v)O_2、P(v-a)CO_2、乳酸、中心静脉血氧饱和度(Scv O_2)、心输出量和APACHEⅡ评分,比较上述指标在预测脓毒症患者预后中的临床价值。收集0、6、24和48 h时P(v-a)CO_2/C(a-v)O_2和心输出量,分析P(v-a)CO_2/C(a-v)O_2与心输出量的关联性。结果与存活组患者比较,死亡组患者入院时P(v-a)CO_2/C(a-v)O_2显著增高,差异有统计学意义(1.642±0.233)vs(1.183±0.186)mm Hg/ml,(P=0.000);C(a-v)O_2显著降低(2.827±1.215)vs(3.349±1.074)ml,(P=0.035);P(v-a)CO_2显著增高(4.625±0.870)vs(3.945±0.781)mm Hg,(P=0.000);乳酸水平显著增高(3.452±2.216)vs(2.218±2.344)mmol/L,(P=0.024);Scv O_2显著降低(62.324±12.226)vs(67.517±10.885)%,(P=0.045);心输出量显著降低(2.571±1.214)vs(3.569±1.345)L/min,(P=0.000);平均APACHEⅡ评分显著增高(25.329±4.234)vs(18.763±10.565),(P=0.000)。P(v-a)CO_2/C(a-v)O_2和心输出量在预测患者死亡中的曲线下面积分别高达0.925和0.920,最佳诊断界值分别为1.412 mm Hg/ml和3.214 L/min。Z检验分析显示,P(v-a)CO_2/C(a-v)O_2和心输出量在预测患者死亡中的曲线下面积明显高于C(a-v)O_2、P(v-a)CO_2、乳酸、Scv O_2和APACHEⅡ评分(P<0.05)。Pearson相关性检验分析显示在0、6、24和48 h时P(v-a)CO_2/C(a-v)O_2和心输出量均显著相关(r=-0.854、-0.901、-0.823和-0.825,P=0.000)。结论 P(v-a)CO_2/C(a-v)O_2在预测脓毒症患者预后中具有良好的临床应用价值,值得进一步推广。Objective To investigate the predictive value of P (v-a) COJC (a-v) O2 in long-term clinical outcome in patients with sepsis. Methods From jan, 2013 to Dec, 2015, a series of patients with sepsis admitted to our hospital were enrolled in this prospective study. The levels of P (v-a) CO2/C (a-v) O2, C (a-v) 02, P (v-a) CO2, lactate, ScvO2, cardiac output and APACHE Ⅱ score on admission were recorded. The predictive values of P (v-a) COJC (a-v)O2, C (a-v)O2, P (v-a) CO2, lactate, ScvO2, cardiac output and APACHE Ⅱ score on admission in long-term clinical outcome in patients with sepsis were compared. Moreover, the levels of P (v-a) CO2/C (a-v)O2 and cardiac output at 0 h, 6 h, 24 h and 48 h were recorded as well and their corrections were analyzed. Results When compared to the survival group, patients in the non-survival group got a significantly higher level of P (v-a) CO2/C (a-v) O2 (1.642 ± 0.233) vs (1.183 ± 0.186) mmHg/ml, (P = 0.000); a significantly lower level of C (a-v) O2 (2.827 ± 1.215) vs (3.349 ± 1.074) ml, (P = 0.035); a significantly higher level of P (v-a) CO2 (4.625 ± 0.870) vs (3.945± 0.781) mmHg, (P = 0.000); a signifieantly higher level of lactate (3.452 ± 2.216) vs (2.218 ±2.344) mmol/L, (P = 0.024); a significantly lower level of SevO2 (62.324± 12.226) vs (67.517± 10.885) %, (P = 0.045); a significantly lower level of eardiae output (2.571±1.214) vs (3.569 ± 1.345) L/min, (P = 0.000); a significantly higher level of APACHE Ⅱ seore (25.329± 4.234) vs (18.763 ± 10.565), (P =0.000). The areas of reeeiver operating eharaeteristie eurve of the predictive values of P (v-a) CO2/C (a-v) 02 and eardiae output in mortality of sepsis were 0.925 and 0.920, and the best cut off values were 1.412 mmHg/ml and 3.214 L/rain. Z test showed that the areas of receiver operating eharaeteristie eurve of the predictive values of P (v-a) CO
