摘要术后低心输出量综合征是儿童先天性心脏病（CHD）术后较为严重的并发症，积极进行心输出量监测，有利于早期识别及合理治疗。经肺热稀释（TPTD）及持续脉搏轮廓分析（PiCCO）是目前儿童常用的监测心输出量的方法。我们特制定此专家共识，目的在于规范TPTD及PiCCO在儿童CHD术后的应用，提高临床医师对于血流动力学参数的认识和分析水平，并在此基础上合理治疗，促进CHD术后患儿恢复。

abstractsPostoperative low cardiac output syndrome is a serious complication for children with congenital heart disease (CHD) after surgery. Active monitoring of cardiac output may be helpful for early identification and rational treatment. Transpulmonary thermodilution (TPTD) and pulse index continuous cardiac output (PiCCO) are commonly used to monitor cardiac output in children. Thus, the purpose of this expert consensus is to standardize the application of TPTD and PiCCO in children after CHD operation, to improve the level of understanding and analysis of hemodynamic parameters by clinicians, and to promote the recovery of children after CHD operation on the basis of reasonable treatment.
