We have evaluated the use of an intravascular ion-selective electrode for continuous plasma potassium monitoring in patients during and after cardiac surgery. Potassium estimations from the indwelling electrode provided a rapid and sensitive, but only moderately reliable, indicator of potassium as confirmed by blood samples. Several significant changes in the plasma potassium were found to occur in the period studied and using this continuous monitor, the precise time course of these changes was recorded.
我们评估了一种血管内离子选择性电极在心脏手术期间及术后患者连续监测血浆钾方面的应用。通过留置电极进行的钾含量测定提供了一个快速且灵敏，但可靠性仅为中等的钾指标，这一点已由血样证实。在所研究的时间段内发现血浆钾出现了几次显著变化，使用这种连续监测仪记录了这些变化的精确时间进程。
