A 23 year-old woman with chronic hypertension, focal segmental glomerular sclerosis with chronic renal insufficiency, and superimposed severe preeclampsia, required cesarean delivery. The patient's course was also complicated by severe hyperkalemia and hypermagnesemia. "PulseCO" pulse contour analysis of a directly measured radial artery pressure tracing, without lithium calibration, enabled her physicians to follow trends in cardiac output and systemic vascular resistance, facilitating and rationalizing her care. The limitations of pulse contour analysis are discussed.
一位 23 岁的女性，患有慢性高血压、局灶节段性肾小球硬化伴慢性肾功能不全和重度子痫前期，需要行剖宫产术。患者的病情还伴有严重的高钾血症和高镁血症。对直接测量的桡动脉压力描记进行“PulseCO”脉搏轮廓分析，无需锂校准，使她的医生能够跟踪心输出量和全身血管阻力的趋势，从而方便并合理地对她进行治疗。本文讨论了脉搏轮廓分析的局限性。
