摘　　要：目的:探讨左心室-动脉耦合对感染性休克患者去甲肾上腺素(NE)影响每博输出量(SV)的预测效果。方法:选取我院于2019年7月—2021年7月期间在ICU明确诊断为感染性休克的患者。依据NE输注后SV的变化程度将患者分为两组,NE致SV增加≥15%认定为SV反应者,纳入SV反应组(S组);NE致SV增加<15%认定为SV无反应者,纳入SV无反应组(N组)。最终S组、N组分别纳入18例、16例患者。记录NE用药剂量、尿量、NE输注至MAP稳定所需时间及累积液体输注量,所有患者均实施经胸超声心动图并记录相关指标。使用logistic回归分析筛选NE导致SV增加的潜在预测因子。绘制Ea/Ees比值、SAP、SV和左室舒张末期容积(LVEDV)的ROC曲线,并计算曲线下面积(AUC)。依据ROC曲线计算Ea/Ees比值、SAP、SV和LVEDV最大约登指数对应的敏感度及特异度。结果:两组患者NE输注至MAP稳定时间的比较差异无统计学意义(P>0.05)。两组患者NE使用剂量和研究期间尿量的比较,差异无统计学意义(P>0.05)。S组NE输注前LVESV值和Ea/Ees比值明显高于N组,Ees则明显低于N组,差异有统计学意义(P<0.05)。S组NE输注后DAP明显高于N组,Ees则明显低于N组,差异有统计学意义(P<0.05)。S组NE输注后左室收缩末期容积(LVESV)、Ea/Ees明显低于NE输注前,差异有统计学意义(P<0.05)。N组NE输注后SAP、DAP、Ea、Ees明显高于NE输注前,差异有统计学意义(P<0.05)。Logistic回归分析结果显示HR、SAP、VTI、SV和LVEDV与SV对NE的反应无明显相关性(P>0.05)。Ea/Ees则与SV对NE的反应存在明显相关性(P<0.05)。LVEDV、SAP、SV的AUC均<0.7,Ea/Ees的AUC为0.924。Ea/Ees的最大约登指数为0.701,对应敏感度为77.8%,特异度为100.0%。结论:输注NE可引起感染性休克患者Ea和Ees的变化,左心室-动脉耦合对感染性休克患者输注NE后SV反应具有预测价值。Objective:Todiscuss the prediction effect of left ventricular-arterial coupling on stroke volume(SV)response to norepinephrine(NE)in patients with septic shock.Methods:Patients diagnosed with septic shock in ICU of our hospital from July 2019 to July 2021 were selected.They were divided into two groups according to the SV change after NE infusion.Patients with≥15%increase in SV caused by NE were identified as SV responsor and included in SV responder group(S group).Patients with<15%increase in SV caused by NE were identified as non-responder to SV and included in the SV non-responder group(N group).Finally,18 and 16 patients were included in group S and group N,respectively.NE dose,urine volume,time required for NE infusion to MAP stabilization and cumulative fluid infusion volume were recorded.Transthoracic echocardiography was performed for all patients and related indicators were recorded.Logistic regression analysis was used to screen for potential predictors of the increase in SV due to NE.The ROC curves of Ea/Ees ratio,SAP,SV and LVEDV were drawn,and the AUC was calculated.The sensitivity and specificity of Ea/Ees ratio,SAP,SV and LVEDV were calculated according to ROC curve.Results:There was no statistical significance in the time from NE infusion to MAP stabilization between 2 groups(P>0.05).There was no significant difference in NE dose and urine volume between 2 groups(P>0.05).Before NE infusion,the LVESV value and Ea/Ees ratio of group S were significantly higher than those of group N,while Ees was significantly lower than that of group N,with statistical significance(P<0.05).After NE infusion,DAP in group S was significantly higher than that in group N,and Ees was significantly lower than that in group N,with statistical significance(P<0.05).The LVESV and Ea/Ees of group S after NE infusion were significantly lower than those before NE infusion,and the difference was statistically significant(P<0.05).SAP,DAP,Ea and Ees of group N after NE infusion were significantly higher than those before NE infus
