Abstract：Objective To investigate the clinical significance of establishing the reporting system of critical value of serum kalium. Methods Serum kalium results from our laboratory between January and June 2012 were reviewed retrospec-tively by using criteria of≤3. 0 mmol/L as low critical value and≥6. 0 mmol/L as high critical value. The hospitalized pa-tients with reported critical value of serum kalium were all followed up for clinic, and their department distribution, distributed situation of serum kalium concentration, mortality rate of varying degree of hyperkalemia or hypokalemia and the time of start-ing treatment were all recorded. Results A total of 2240 in 114 847 (1. 95%) results were at critical value, which were mainly from inpatients. There were 617 patients with low critical value of serum kalium and 201 patients with high critical val-ue of serum kalium. A total of 120 patients died (10. 51%), and the mortality rate was high in patients with serum kalium lower than 2. 50 mmol/L or higher than 6. 50 mmol/L. The results showed that the more serious hypokalemia or hyperkalemia was, the shorter the time for clinicians responding to the critical results was. Conclusion Establishing a reporting system of critical value of serum kalium in laboratory has important significance to clinical treatment for serious electrolyte disorder and prognosis improvement.
