Agreement between Central Venous and Arterial Blood Gas Measurements in the Intensive Care Unit

Abstract: Background and objectives: Venous blood gas (VBG) analysis is a safer procedure than arterial blood gas (ABG) analysis and may be an alternative for determining acid-base status.

“…Richard Treger. 15 There was great similarity in correlation coefficients for pH,PCO2 HCO3 in our study and study done by Richard Treger. 15 Thus a number of studies have suggested agreement between AVG and VBG values, although most of the previous studies were limited by specific patient group samples (e.g.…”

“…14 Venous blood gas (VBG) analysis clearly does not replace ABG analysis in determining exact Po2 status, and arterial puncture may still be required for invasive arterial BP monitoring, but given the well-accepted accuracy of pulse oximetry, VBG analysis may be a safer alternative to ABG analysis for determining acid-base status, reducing the need for frequent invasive arterial sampling. 15 A few authors have expressed doubts the use of VBG values in lieu of arterial values. The aim of this study is to investigate the agreement between ABG and Central VBG samples for all commonly used parameters (pH, Pco2, Hb% saturation and bicarbonate) in a pathologically diverse ICU patient population.…”

“…It also avoids the inherent risks of performing an arterial puncture. Venous base excess has been shown to correlate well with arterial base excess in critically ill, (10)(11)(12) mechanicallyventilated trauma (13) and acute trauma patients. (14)(15)(16) In addition, it has been suggested that venous base excess better reflects overall tissue perfusion and is therefore a better predictor of severity of shock and mortality.…”

“…Nos seres humanos, a análise da gasometria arterial (GA) é comumente realizada para avaliação clínica, mas o processo tem certas limitações como a aceitação do paciente (uma vez que o procedimento pode ser doloroso) e o potencial de causar complicações como lesão arterial, trombose com isquemia distal, hemorragia, hematoma, formação de aneurisma, danos aos nervos medias e, raramente, distrofia simpática reflexa. Além disso, o procedimento apresenta risco, pequeno mas significativo, em deflagrar ferimentos por picada de agulha nas pessoas envolvidas na coleta do sangue (MALATESHA et al, 2007;TREGER et al, 2010). A análise dos gases no sangue venoso (GV) requer menor manipulação do animal, é um procedimento relativamente mais seguro para o paciente e para o profissional de saúde, e é uma alternativa para a análise da GA para o equilíbrio ácido-base.…”

“…Estudos recentes tem demonstrado a correlação entre os valores da GA e da GV (MALATESHA et al, 2007;MIDDLETON et al, 2006). A análise da GV não substitui a análise da GA na determinação da pressão parcial arterial de oxigênio (PaO 2 ), e a punção arterial pode ser necessária para monitorização da pressão arterial invasiva, mas dada a boa precisão da oximetria de pulso, a análise da GV é uma alternativa mais segura do que a análise da GA para determinar o equilíbrio ácido-base e a pressão parcial venosa de gás carbônico (PvCO 2 ), reduzindo a necessidade de amostragem arterial invasiva (TREGER et al, 2010).…”
