摘要(Abstract):

目的探讨中心静脉氧饱和度(central venous oxygen saturation,ScvO_2)与混合静脉氧饱和度(mixed venous oxygen saturation,SvO_2)对先天性心脏病(congenital heart disease,CHD)合并肺动脉高压(pulmonary arterial hypertension,PAH)患者修补术后评估价值的一致性。方法本研究前瞻性选取2016年3月至2017年3月,于河南省人民医院、北京阜外医院、广州中山大学第八附属医院及四川省广元市第一人民医院接受治疗且符合入选及排除标准的43例CHD-PAH患者,分别于停体外循环后即刻及转入重症监护室后6、12、24、48 h等5个时间点,同时测量ScvO_2及SvO_2,并记录血流动力学参数、血红蛋白及乳酸等指标。采用Bland-Altman检验分析两个指标的一致性,采用线性回归分析两指标偏倚的相关影响因素。结果 ScvO_2和SvO_2的总体相关系数R2=0.369,体外循环后即刻R2=0.369,体外循环后即刻R2=0.515,入重症监护室后6、12、24、48 h的R2=0.515,入重症监护室后6、12、24、48 h的R2分别为0.375、0.605、0.712、0.252。Bland-Altman检验显示ScvO_2与SvO_2的偏倚(△ScvO_2﹣SvO_2)为-1.3%,一致性区间(limits of agreement,LOA)为(-17.0%,14.4%)。总体上氧摄取率(oxygen extraction rate,O2ER)(R2分别为0.375、0.605、0.712、0.252。Bland-Altman检验显示ScvO_2与SvO_2的偏倚(△ScvO_2﹣SvO_2)为-1.3%,一致性区间(limits of agreement,LOA)为(-17.0%,14.4%)。总体上氧摄取率(oxygen extraction rate,O2ER)(R2=0.030,P<0.05)、肺动脉收缩压(R2=0.030,P<0.05)、肺动脉收缩压(R2=0.030,P<0.05)和心率(R2=0.030,P<0.05)和心率(R2=0.032,P<0.05)对△ScvO_2-SvO_2的影响较小;当ScvO_2<70%时,O2ER(R2=0.032,P<0.05)对△ScvO_2-SvO_2的影响较小;当ScvO_2<70%时,O2ER(R2=0.203,P<0.01)、肺动脉收缩压(R2=0.203,P<0.01)、肺动脉收缩压(R2=0.110,P<0.01)、心率(R2=0.110,P<0.01)、心率(R2=0.150,P<0.01)对△ScvO_2-SvO_2的影响则较大,此时ScvO_2有低估SvO_2的趋势,而当ScvO_2≥70%时,ScvO_2会高估SvO_2。机械通气期间ScvO_2与SvO_2的偏倚为-1.3%,LOA为(-16.1%,13.5%),△ScvO_2-SvO_2的影响因素为O2ER(R2=0.150,P<0.01)对△ScvO_2-SvO_2的影响则较大,此时ScvO_2有低估SvO_2的趋势,而当ScvO_2≥70%时,ScvO_2会高估SvO_2。机械通气期间ScvO_2与SvO_2的偏倚为-1.3%,LOA为(-16.1%,13.5%),△ScvO_2-SvO_2的影响因素为O2ER(R2=0.122,P<0.01);撤机后ScvO_2与SvO_2的偏倚为-1.3%,LOA为(-19.5%,16.8%),△ScvO_2-SvO_2的影响因素为O2ER(R2=0.122,P<0.01);撤机后ScvO_2与SvO_2的偏倚为-1.3%,LOA为(-19.5%,16.8%),△ScvO_2-SvO_2的影响因素为O2ER(R2=0.320,P<0.01)和动脉氧饱和度(R2=0.320,P<0.01)和动脉氧饱和度(R2=0.320,P<0.01)。结论CHD-PAH患者术后监护中ScvO_2不能替代SvO_2的评估价值。当ScvO_2≥70%时,宜同时监测ScvO_2与SvO_2以排除低灌注状态。
Objective This study aimed to investigate the agreement of central venous oxygen saturation( ScvO_2) with mixed venous oxygen saturation( SvO_2) in postoperative care of congenital heart disease( CHD)with pulmonary arterial hypertension( PAH).

Data of ScvO_2 and SvO_2 were synchronously collected after cardiopulmonary bypass( CPB),and 6,12,24,and 48 hours after admission to the intensive care unit. In addition,hemodynamic parameters,hemoglobin,and arterial lactate were recorded. Data were analyzed by Bland-Altman test and linear regression analysis.Results The overall R2=0.320,P<0.01)。结论CHD-PAH患者术后监护中ScvO_2不能替代SvO_2的评估价值。当ScvO_2≥70%时,宜同时监测ScvO_2与SvO_2以排除低灌注状态。

Bland-Altman test indicated during mechanical ventilation the mean bias of ScvO_2 and SvO_2( △ScvO_2-SvO_2) was-1. 3% and LOA were-16. 1%to 13. 5%,the only factor influencing △ScvO_2-SvO_2 wasO_2 ER( R2= 0. 150,P < 0. 01) were much greater,and ScvO_2 would underestimate SvO_2; ScvO_2 might overestimate SvO_2 when ≥ 70%.
