In this case, a 43-year-old male presents to the emergency department complaining of blurred vision during the past few days. He appears apprehensive. His eye examination is completely normal. On the basis of his increased respiratory rate and apprehension, a diagnosis of anxiety state is made, and he is discharged home. He returns the next day with continuing symptoms. On this occasion, an arterial blood gas is ordered, which eventually reveals his correct diagnosis.

The aim of this study was to compare simultaneously obtained arterial and capillary blood gas (CBG) values in comatose-poisoned patients presented with stable vital signs. Forty-five adult patients with a diagnosis of coma because of poisoning and stable vital signs were included in this prospective study. With respect to pH, the arterial blood gas (ABG) and CBG values correlated satisfactorily (r2 = .91) and had an acceptable limit of agreements (LOAs; —0.04 to 0.06). With respect to base excess (BE), the ABG and CBG values correlated well (r2 = .85), but their 95% LOAs seem too wide to allow substitution (—4.4 to 2.7). PCO2 (r2 = .61), HCO3 (r2 = .71) and PO2 (r2 = .53) correlated less reliably. A capillary PCO2 of 51.7 mm Hg had a sensitivity of 100% and a specificity of 95.12% for detecting hypercarbia (area under the curve, 0.99; 95% Confidence Interval, 0.90-0.99; p < .0001). In conclusion, CBG analysis for pH may be a reliable substitute for ABG analysis in the initial evaluation of patients presenting with coma and stable vital signs to the poisoning emergency department (PED). Subsequent ABG may be required in patients with capillary PCO2 > 51.7 mm Hg.

Abstract 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, mean age 63.55±16.82) and 400 patients (65.25% male, mean age 62.86±15.65) were enrolled in PHS and DABS groups, respectively. Compared with PHS group, DABS had a quite higher correlation coefficient in K + (0.923 vs. 0.855), Na + (0.911 vs. 0.850) and the differences between venous and arterial of all indicators (K + 0.202mmol/L vs. 0.318mmol/L, P<0.0001; Na + 1.187mmol/L vs. 2.902mmol/L, P<0.0001; Cl - -5.336mmol/L vs. –7.598mmol/L, P<0.0001; Hb -0.898g/L vs. 2.212g/L, P<0.0001; HCT -0.659% vs. 1.269%, P<0.0001) were significantly smaller in DABS group.Conclusion High accuracy was seen in arterial blood results irrespective of the usage of PHS or DABS for sample collection. DABS showed more accurate and stable results, suggesting its role for future medical use.

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<0.0001), Sodium=2.902±2.709 mmol/L (P<0.0001), Chloride=–7.598±5.060 mmol/L (P<0.0001), Hemoglobin (Hb)=2.212±7.992 g/L (P<0.0001), Hematocrit (HCT)=1.269±2.861% (P<0.0001). Correlation coefficients were: Potassium=0.855 (P<0.0001), Sodium=0.850 (P<0.0001), Chloride=0.742 (P<0.0001), Hb=0.967 (P<0.0001), and HCT=0.955 (P<0.0001). Mean differences from DABS group were: Potassium=0.202±0.276 mmol/L (P<0.0001), Sodium=1.187±2.346 mmol/L (P<0.0001), Chloride=–5.336±6.116 mmol/L (P<0.0001), Hb=-0.898±9.998 g/L (P=0.073), HCT=–0.659±3.228% (P<0.0001). Correlation coefficients were: Potassium=0.923 (P<0.0001), Sodium=0.911 (P<0.0001), Chloride=0.688 (P<0.0001), Hb=0.951 (P<0.0001), and HCT=0.943 (P<0.0001). After sensitivity analysis, the same but more reliable results were observed. Conclusion High accuracy was seen in venous and arterial blood results irrespective of the usage of PHS or DABS for sample collection. DABS showed more accurate and stable results, suggesting its role for future medical use.
