Özet:

 Objective: In our study, we aimed to find out whether the parameters of venous blood gas analysis are reliable. Methods: Patients over the age of 18 years who presented to our emergency department between 01.10.2021 and 31.03.2022 and whose venous blood gas was taken simultaneously with the blood tests requested from the patients were included in the study. Blood biochemical tests potassium, sodium, hemoglobin, hematocrit and blood glucose levels and venous blood gas obtained simultaneously; Ph, potassium, sodium, hemoglobin, hematocrit and blood glucose levels were recorded on the patient intake form. Pearson correlation coefficients were calculated for each parameter; r 0.8 was considered a strong correlation. A Bland-Altman test with 95 confidence interval CI limits of agreement was used to assess the agreement between the central biochemistry laboratory auto analyzer and venous blood gas analysis results. Results: The results of 933 patients who presented to the emergency department and had venous blood gas analysis were analyzed and 582 patients were included in the study. Correlations between venous blood gas and central laboratory results showed a strong correlation for glucose level r0.91, hemoglobin r0.93, hematocrit r0.89 and potassium r0.80, and a weak correlation for sodium r0.69. According to Bland-Atman analysis, there was acceptable agreement for potassium, hemoglobin and hematocrit measurements for clinical use, but poor agreement for glucose and sodium measurements. Conclusion Considering the limits of agreement, potassium, hemoglobin and hematocrit values were acceptable, while glucose and sodium values were not acceptable. Clinicians should be aware of the limitations when using venous blood gas results.

 Amaç: Çalışmamızda venöz kan gazı analizi parametrelerinin güvenilir olup olmadığını bulmayı amaçladık. Yöntem: Acil servisimize 01.10.2021- 31.03.2022 tarihleri arasında başvuran 18 yaş üstü, hastalardan istenen kan tetkikleriyle eş zamanlı venöz kan gazı alınan hastalar çalışmaya alındı. Hastalardan alınan kan biyokimyasal tetkiklerinden potasyum, sodyum, hemoglobin, hematokrit ve kan glukoz düzeyi ve eş zamanlı alınan venöz kan gazında; Ph, potasyum, sodyum, hemoglobin, hematokrit ve kan glukoz düzeyi hasta alım formuna işlendi. Her parametre için Pearson korelasyon katsayıları hesaplandı; r 0.8 değeri güçlü bir korelasyon olarak kabul edildi. Merkezi biyokimya laboratuvarı oto analizörü ve venöz kan gazı analizi sonuçları arasındaki uyumu değerlendirmek için 95 güven aralığı CI uyum sınırları olan bir Bland-Altman testi kullanıldı. Bulgular: Acil servise başvuran ve venöz kan gazı alınan 933 hastanın sonuçları incelendi ve 582 hasta çalışmaya alındı. Venöz kan gazı ve merkezi laboratuvar sonuçları arasındaki korelasyonlar değerlendirildiğinde glukoz düzeyi için r0.91, hemoglobin için r0.93, hematokrit için r0.89 ve potasyum için r0.80 güçlü bir korelasyon olduğu görüldü. sodyum için ise  r0.69 zayıf bir korelasyon vardı. Bland-Atman analizine göre klinik kullanım için potasyum, hemoglobin ve hemotokrit ölçümleri için kabul edilebilir uyum olmasına rağmen, glukoz ve sodyum ölçümleri için zayıf bir uyum olduğu bulundu. Sonuç Uyum limitleri dikkate alındığında potasyum, hemoglobin ve hemotokrit değerlerinin kabul edilebilir, glukoz ve sodyum değerleri kabul edilebilir değildi. Klinisyenlerin venöz kan gazı sonuçlarını kullanması gerektiğinde kısıtlılıkların farkında olmalıdır.
