To Study Arterial And Venous Blood Gas Sample For Diagnosis Of Acid Base Abnormality In Patient With Diabetes Ketoacidosis
Background: To study the values of Arterial Blood Gas (ABG) and Venous Blood Gas (VBG) sample for comparison of pH, HCO3 and pCO2 values in patients presenting with Diabetic KetoAcidosis. To determine Degree of Agreement between these values in such patient. To assess whether VBG analysis can replace ABG analysis in initial evaluation of patients presenting with DKA. Material & Methods: The observational comparative study was carried out on 38 patients above the age of 17 years presenting with Diabetic ketoacidosis admitted in Emergency Ward (EW) of medicine department at Tertiary Health Center, South Gujarat. Results: Strong linear correlation was found between Arterial and Venous pH, HCO3 and CO2 values and Venous pH and HCO3 is almost equivalent to that of Arterial, but according to the Degree of agreement Venous pCO2 is not equivalent to Arterial pCO2; so Venous pH and HCO3 can be used in place of Arterial pH and HCO3 in initial evaluation of DKA patient but not Venous pCO2. Conclusion: For initial evaluation of DKA patients (for pH and HCO3 determination), we can use VBGA in place of ABGA, as ABGA is technically more difficult, more painful, and carries higher incidence of complications.
