Background Arterial blood gas (ABG) analysis is vital in the emergency department. However, the accuracy and stability of some indicators in ABG analysis are debatable compared with venous ones. Disposable arterial blood syringe (DABS) usage is increasing in clinical practice. To compare the accuracy and stability of venous versus arterial blood results and newly emerging DABS versus traditionally used pre-heparinized syringe (PHS) results, we performed this study. Methods This retrospective study was performed at the emergency department of the Third Xiangya Hospital of Central South University. Participants were divided into two groups PHS and DABS, from which venous and arterial blood was drawn and analyzed either in laboratory or ABG-analyzer. Blood sample results were compared by the Pearson correlation coefficient and t-test. By removing extreme results, the sensitivity analysis was conducted. Results A total of 500 patients (64.80% male) and 400 patients (65.25% male) were enrolled in PHS and DABS groups, respectively. Mean differences of blood sample results between venous and arterial from PHS group were: Potassium=0.318±0.396 mmol/L (P |
