Abstract Transcutaneous pCO2 electrode response time was optimized by use of a new electrode filling solution composed of NaCl/NaHCO3 electrolyte buffer (100 and 20 mmol/L, respectively) in an equivolume mixture of glycerol and water. The 95% response time to a step change in pCO2 was 49.9 +/- 2.8 s (mean +/- SD) when there was no spacer between the membrane and glass of the electrode. Use of this filling solution during monitoring of severely ill premature infants with cardiopulmonary disease allowed identification of large, unpredictable transient changes in transcutaneous pCO2, and therefore presumably in arterial pCO2, that occurred during capillary blood gas sampling. The changes, which occurred in 19 of 20 samplings, ranged from -1.06 + 2.53 kPa (-8 to +19 Torr). The maximum relative change observed was +29%. These results indicate that the standard protocol for capillary blood collection induces significant transient fluctuations in blood gas tensions. We believe these fluctuations decrease the reliability of capillary pCO2 values for use in clinical management in patient populations similar to ours.

Arterial blood gas (ABGs) analysis forms the cornerstone of emergency respiratory investigation. In many situations values obtained dictate management strategy and facilitate decision-making. It is an uncomfortable procedure for the patients and if repeated ABGs are required, consider whether less invasive measures, such as respiratory rate, pulse oximetry or capillary blood gas measurements could be used....

AbstractBackgroundThe aim of the present study was to compare hemoglobin (Hb) levels determined by point-of-care testing (POCT) HemoCue® and arterial blood gas analyzer using an automated hematology analyzer in critically ill geriatric patients.MethodsForty geriatric patients requiring intensive care treatment were included in the study. Arterial blood sample was analyzed using HemoCue® (HemoCue®; Hb 201+, Angelholm, Sweden) (HbHemoCueArterial), blood gas analyzer (Techno Medica, Gastat1800 series, Japan) (HbBGA) and an automated hematology analyzer (Cell Dyne 3700 System, Abbott Laboratories, USA) (HbLab) as a reference method. Capillary blood measurements were performed (HbHemoCueCapillary) using HemoCue® at bedside. Bland-Altman analysis was applied to the results.ResultsWe found a positive correlation between the Hb measurements of HemoCueCapillary, HemoCueArterial and automated hematology analyzer (r-values were 0.799 and 0.922, respectively) and p<0.001. There was also a positive correlation between the Hb measurements of blood gas analyzer and automated hematology analyzer (r = 0.878) and p<0.001. The bias and limits of agreement were 0.32 and −2.5±3.14 g/dL for the HbHemoCueCapillary, 0.64 and −1.03±2.31 g/dL for the HbHemoCueArterial and −1.2 and −4.45±2.05 g/dL for the HbBGA. Inotropic agent administration did not affect the Hb values in all groups.ConclusionsBoth HemoCueCapillary and HemoCueArterial are sufficiently accurate and correlated with automated hematology analyzer in geriatric critically ill patients if used correctly. In terms of Hb levels, arterial and capillary blood sample measurements with HemoCue® provided more clinically acceptable accuracy than blood gas analysis system.

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.
