What does this mean for outcomes?
What does these mean on outcomes? The influence of potassium disorders especially hyperkalemia on outcomes has not been established
Potassium & Intraoperative dysrhythmias correlated with preoperative dysrhythmias Arrhythmias If present, there was a higher incidence intraop But NOT correlated to HIGH potassium levels Vitez TS, Soper LE, Wong KC, Soper P. Chronic hypokalemia and Intraoperative Dysrhythmias. Anesthesiology 1985; 63: 130-3.
