“…According to Jain A et al, the cause for lower values of electrolytes in arterial blood is because of binding of heparin to electrolytes [11]. R King et al, observed that there was good agreement between the sodium and potassium values measured by ABG analyser and chemistry autoanalyser [12].…”

“…electrolyte analyzer with Indirect ISE i.e. auto analyzer where some studies have shown no similarity between parameters and some showed similarity with potassium but not for other [10] as both principles employed in analysis for electrolyte measurement were different so results in each study differed. But in our study we have observed that there are significant differences in the values in all the ranges.…”

Our aim is to determine whether the serum electrolytes (Sodium and Potassium) measured by two different methods on two different equipments are equivalent or not. This retrospective study was conducted over three months period (June 2017-August 2017. A total number of 300 patients from intensive care unit or in the different wards with a variety of diagnoses were enrolled in this study. Analysis of sodium and potassium levels in their serum was carried out using an electrolyte analyzer and an auto-analyzer. Statistical measures were applied using students paired t-tests. The Mean level (± standard deviation) of sodium measured by electrolyte analyzer was statistically significantly higher than the auto-analyzer values (139.99 ± 7.48 mmol/l and 137.15 ± 7.66 mmol/l respectively; P˂0.0001). Regarding the potassium levels, the Mean level (± standard deviation) measured by electrolyte analyzer was statistically significantly greater than that of potassium measured by auto-analyzer (4.290 ± 0.743 mmol/l and 4.147 ± 0.738 mmol/l respectively; p˂0.0001). Our results showed that serum electrolytes levels measured by electrolyte analyzer were higher than those measured by auto-analyzer. Differences obtained were statistically significant.

Son zamanlarda yapılan çalışmalarda venöz kan gazının pH, pCO 2 ve bikarbonat değerlendirilmesi amacıyla arteryal kan gazı yerine kullanılabileceği gösterilmektedir (1-3). Ayrıca venöz kan gazı kullanımı ile arteryal kan gazı alımı sırasında hastada ve sağlık çalışanlarında oluşabilecek komplikasyonlar azaltılabilmektedir (3). Kan gazı analizinde pH, bikarbonat, pCO 2 ve pO 2 'nin yanısıra sodyum, potasyum ve kalsiyum gibi elektrolit değerleri de ölçülebil-mektedir. AbstractObjective: To compare venous blood gas potassium levels, which provides rapid results, with laboratory potassium levels. Material and Methods:We reviewed the data of patients who had been referred to our emergency service between January 1 2011 and March 21 2011. Concurrent venous blood gas potassium levels and laboratory potassium levels from 99 patients were included. The data were analyzed using SPSS for Windows version 9.0. Results: Laboratory potassium levels were found to be 4.5 mmol/l (SD 0.86 mmol/l, 95% CI 4.32-4.66 mmol/l, min. 3.1 mmol/l, max. 7.3 mmol/l). Venous blood gas potassium levels were found to be 3.94 mmol/l (SD 0.79 mmol/l, 95% CI 3.78-4.09 mmol/l, min. 2.25 mmol/l, max. 6.37 mmol/l). The difference between laboratory potassium levels and venous blood gas potassium levels was 0.56 mmol/l (SD 0.41 mmol/l, 95% limits of agreement were from -0.24 mmol/l to 1.36 mmol/l, 95% CI 0.48-0.64 mmol/l). Both potassium levels were highly correlated (r= 0.882, p<0.001). Laboratory potassium levels were higher than venous blood gas potassium levels in 97% of patients. Conclusion: In this study, laboratory potassium levels were found to be higher than venous blood gas potassium levels. According to these results, venous blood gas potassium levels cannot be used in place of laboratory potassium levels. However, in emergency services, blood gas potassium levels may be used for especially critical patients until laboratory potassium levels are obtained. Further investigations are needed on this topic. (JAEM 2012; 11: 73-6 Venöz kan gazı potasyum değerleri ortalama 3.94 mmol/l (SD 0.79 mmol/l, %95 CI 3.78-4.09 mmol/l, min: 2.25 mmol/l,max: 6.37 mmol/l) bulundu. Laboratuar potasyum değerleri ile venöz kan gazı potasyum değerleri arasındaki ortalama fark 0.56 mmol/l (SD 0.41 mmol/l, %95 uyumluluk sınırı -0.24 mmol/l ile 1.36 mmol/l arası, %95 CI 0.48-0.64 mmol/l p<0.001) bulundu. Korelasyon katsayısı (r=0.882 p<0.001) sonuçlar arasında anlamlı derecede pozitif korelasyon bulundu. %97'sinde (n=96) laboratuar potasyum sonuçları venöz kan gazı potasyum sonuçlarından daha yüksekti. Sonuç: Bu çalışmada laboratuar potasyum değerleri ile venöz kan gazı potasyum değerleri arasında anlamlı fark bulundu. Bu sonuca göre venöz kan gazı potasyum değeri laboratuar potasyum sonuçları yerine kullanılması uygun değildir. Ancak acil servislerde özellikle hızlı tedavi kararlarının verilmesi gereken kritik hastalarda venöz kan gazı potasyum değerleri laboratuar sonuç-ları çıkana kadar potasyum değerini tahmin etmede kullanılabilir.
