Abstract

It is aimed to investigate the utility of blood gas electrolyte and glucose values in place of biochemical electrolyte and glucose values in Emergency Department (ED). The group of patients, whose blood gas electrolyte , glucose and also biochemical electrolyte and glucose values were examined, These data were derived from 1007 patients at the age of 18 and older, who were admitted to Uludag University ED and whose blood gas values were examined between July 2011 and October 2011. While biochemistry K+ median was 4,2 mmol/L, blood gas K+ median was 3,86 mmol/L. When blood gas and biochemical K+ values were compared, average difference was -0,4 mmol/L (95% confidence limits: -1,5-0,7 mmol/L) and correlation coefficient was r=0.794 (p

Acil serviste kan gazı değerlerinin biyokimyasal değerler yerine kullanılabilirliği

Abstract

Bu çalışmanın amacı acil serviste kan gazı elektrolit ve glukoz değerlerinin biyokimyasal elektrolit ve glukoz değerleri yerine kullanılabilirliğini araştırmaktır. Uludağ Üniversitesi Acil servisine Temmuz 2011 ile Ekim 2011 tarihleri arasında başvuran ve acil serviste kan gazı bakılan 18 yaş ve üzeri 1007 hastadan; kan gazı elektrolit ve glukoz ile biyokimyasal elektrolit ve glukoz değerlerinin bakıldığı grup çalışmaya alınmıştır. Biyokimya K+ ortanca:4,2 mmol/L iken, kan gazı K+ ortanca:3,86 mmol/L idi. Kan gazı ve biyokimyasal K+ değerleri karşılaştırıldığında ortalama fark -0,4 mmol/L (%95 uyum sınırları: -1,5-0,7 mmol/L), korelasyon katsayısı (r=0,794 p
