shock state, poor pick up) painful (should be performed with local anaesthetic in conscious patients) Venous blood gas (VBG) interpretation . Arterial blood gases (ABGs) are commonly used for estimating the acid-base status, oxygenation and carbon dioxide concentration of unwell patients. However, arterial blood can be difficult to obtain due to weak pulses or patient movement. Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO2 of 40 mmHg (5.3 kPa), while a base deficit (ie. a negative base excess) is defined by the amount of strong base that must be added. The formula for base deficit is as follows: 2012-07-13 · Rudkin et al studied 385 trauma patients requiring ABGs to see if venous pH and calculated base excess (BE) were similar to those values in an ABG . A priori, 15 physicians blinded to the study hypothesis set a consensus single threshold of <0.05 pH units and a variance in BE <2 as the greatest accepted difference between an ABG and VBG. 2015-12-16 · pH, PCO2 (if normocapnic), HCO3 and base excess from a VBG are usually adequate for clinical decision making SpO2 is usually sufficient for clinical decision making unless pulse oximetry is unreliable for other reasons (e.g.

Arterial blood gases are used to analyze the acid/base balance Agreement between arterial and central venous values for pH, bicarbonate, base excess, and lactate. Emerg Med J. 2006 Aug;23(8):622-4. Yıldızdas D et al. Introduction: To compare the use of arterial blood gas (ABG) base deficit and Hypothesis: Moderate VBG base deficit is less predictive of pediatric trauma IN ELDERLY SEPSIS PATIENTS: ALACTATE BASE EXCESS SHEDS SOME LIGHT .
Base excess – beyond the basics – Blodgas.se
BE is the amount of required acid or base to bring the pH of the totally oxygenated blood to 7.40 at 37°C and 40 mmHg PCO2; it is the indicator of the metabolic status.

Performing Laboratory Saint Lukes Regional Medical Center-Specimen Collection 2014-10-14 · Jane’s VBG result was pH 7.26, pCO 2 16 mm Hg (2.13 kPa), HCO 3 7.1 mmol/L, K 3.8 mmol/L, base excess (BE) −14 mEq/L and lactate 7.2 mmol/L. The evidence There are 13 studies exploring arteriovenous agree-ment of pH.2 They have a total of 2009 patients, but individual studies range in size from 44 to 346 patients. Weighted mean difference Hypothesis: Central venous blood gas (VBG) measurements of pH, PCO 2, and base excess can be substituted for the same values obtained from an arterial blood gas (ABG) analysis in mechanically ventilated trauma patients, obviating the need for arterial puncture. In contrast, base excess (BE), representing the degree of metabolic compensation of respiratory acidosis, is probably a more stable marker due to the inertia of the compensatory mechanisms .
VBG may eventually take the place of ABG analysis in determining acid–base status.

The base excess increases in metabolic alkalosis and decreases (or becomes more negative) in metabolic acidosis, but its utility in interpreting blood gas results is controversial. Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO2 of 40 mmHg (5.3 kPa), while a base deficit (ie. a negative base excess) is defined by the amount of strong base that must be added. 2015-12-16 2018-10-15 central venous base excess versus arterial bases excess Just three studies [22-24] compared central venous and arterial base excess (BE)(see Table V). Mean A-V difference was small (–0.19 mmol/L and –0.18 mmol/L) and 95 % limit of agreement was sufficiently narrow for one study author to conclude that central venous and arterial values are interchangeable .
