Influence of Dyskalemia at ICU Admission and Early Dyskalemia Correction on Survival
ccforum.biomedcentral.comDyskalemia is common at ICU admission and associated with increased mortality. Occurrence of cardiac events increased with dyskalemia depth.
A correction of serum potassium level by day 2 was associated with improved prognosis.
Of 12,090 patients at 22 French OUTCOMEREA network ICUs, 2,108 (17.4%) had hypokalemia and 1445 (12%) had hyperkalemia.
Prognostic impact of dyskalemia and its correction was assessed using multivariate Cox models.
After adjustment, hypokalemia and hyperkalemia were independently associated with a greater risk of 28-day mortality.
Patients were classified into six groups according to their serum potassium level at admission.
