超声心输出量监测仪是一种无创、连续波多普勒监测仪，可用于测量心输出量。其在围手术期和重症监护中的准确性和精密度已被评估，结果各不相同。我们进行了一项荟萃分析，以计算该器械的合并平均偏倚、精密度和误差百分比。6项研究适合纳入由320个测量值组成的汇总参数分析。平均加权偏倚为-0.39 l.min-1（95% CI -0.25至-0.53 l.min-1），精密度为1.27 l.min-1，百分比误差为42.7%（95% CI 38.5-46.9%）。超声心输出量监测仪与推注热稀释法达到了与围手术期心输出量监测的其他微创方法相似的一致性，并可能在心输出量监测中发挥有用的作用。
The ultrasonic cardiac output monitor is a non-invasive, continuous-wave Doppler monitor that can be used to measure cardiac output. Its accuracy and precision in peri-operative and critical care has been assessed with varied results. We conducted a meta-analysis to calculate a pooled mean bias, precision and percentage error for this device. Six studies were suitable for inclusion into a pooled parametric analysis consisting of 320 measurements. The mean weighted bias was -0.39 l.min-1 (95% CI -0.25 to -0.53 l.min-1), precision 1.27 l.min-1 and percentage error 42.7% (95% CI 38.5-46.9%). The ultrasonic cardiac output monitor achieved similar agreement with bolus thermodilution to that of other minimally invasive methods of peri-operative cardiac output monitoring, and may have a useful role in cardiac output monitoring.
