Clinica Chimica Acta:监护仪“StatStrip®Xpress™”测量胎儿血乳酸的可靠性

测定胎儿血乳酸用来评估厌氧代谢的程度。在获取足够的头皮血液供血气分析仪分析的技术难题中,一般提倡使用床旁检测设备。

测定胎儿血乳酸用来评估厌氧代谢的程度。在获取足够的头皮血液供血气分析仪分析的技术难题中,一般提倡使用床旁检测设备。目前,StatStrip®Xpress(SSX)已显示出良好的性能,但在实施胎儿监测之前还需要进一步评估。

本研究采用SSX和参照方法ABL800™同时分析112例新生儿的动脉/静脉脐血。采用SSX321例心率异常胎儿头皮血进行反复采样分析。

ABL800™乳酸范围在动脉中为1.9-13.3mmol / L,在静脉脐血中为1.5-10.2mmol / L,与SSX具有极好的相关性(R2 = 0.95)。与参考方法相比,SSX值较低,低值为-0.79mmol / L,高值为-1.68mmol / L.脐带血和头皮血液SSX值的平均CV分别为:乳酸≤3mmol/ L7.1%,8.4;乳酸> 3mmol / L 3.8%,分别为6.8%。用SSX重复测量相同样品,其中脐带/头皮血液没有显著差异(p = 0.11)。

ssx -乳酸值一直降低,但与参考方法相关性极好。对脐带血和头皮血的重现性较好。我们建议SSX作为一种有前景的测量胎儿乳酸的设备。
