Abstract:

Objective

To analyze the distribution of the urgent value of serum potassium in the Second Hospital of Wenzhou Medical University in 2013, and to provide the adjustment basis for determining the value of potassium in different clinical departments.

Methods

Retrospective datas investigation.The data was collected by the laboratory management software developed by the center of information technology in our hospital. The total number of urgent value of serum potassium (the range of urgent value of serum potassium in our hospital was low K≤3.0 mmol/L and high K≥6.0 mmol/L), the total number of serum potassium in 2013, and the reporting rate of urgent value of serum potassium were statisticed.The clinical department distribution and the clinical treatment rate of serum potassium was evaluated.

Results

The reporting rate of urgent value of serum potassium was 2.1%(4661/218918) in the second hospital of Wenzhou Medical University in 2013. The urgent value of serum potassium distributed primarily within K≤3.0 mmol/L range, accounting for 79.02% (3683/4661); and the total number of the urgent value of serum potassium within K≥6.0 mmol/L range was 20.98%（978/4661). The ward with the total number of urgent value of serum potassium at first three were department of internal (respiratory, digestive,blood), kidney dialysis /centers of gastrointestinal, department of hepatobiliary surgery, The constituent ratios were 12.9% (465/3605), 9.63% (347/3605), and 8.02% (289/3605). The treatment rate of hyperkalemia in patients without neonatal ward was 99.1% (329/332); The treatment rate of hypokalemia in patient was 98.8% (660/668). The total treatment rate was 98.9% (989/1000). In neonatal ward, the treatment rate of hyperkalemia was 18.5% (15/81), the treatment rate of hypokalemia was 100% (33/33). In eonatal ward the total processing was 42.1% (48/114).

Conclusions

Existing potassium urgent value range is applicable to all major wards (except neonatal ward), The rate of clinical treatment for hyperkalemia is not appropriate in neonatal ward in the hospital. Paediatricians suggest the feasibility of increasing the upper limit of the urgent value in neonatal ward. It is essential to establish a more scientific and reasonable range of urgent value of serum potassium in neonatal ward, which can eliminate the physiological jaundice of newborn period when they are over the critical value range of hyperkalemia.
