Acid Base Status

Objective: This study was aimed to compare between arterial and peripheral venous samples for blood gases and acid base status in critically ill patients and to evaluate if venous sample is a better alternative for initial assessment and resuscitation.Methods: This prospective study was conducted on 50 patients of more than 18 years of age in the department of Critical Care Medicine, BIRDEM General Hospital. Arterial and peripheral venous samples were taken within five minutes of each other and analyzed immediately for blood gases and acid base status. Mean difference and Pearson's product moment correlation coefficient was used to compare the result.Results: Mean difference and correlation coefficient between arterial and peripheral venous sample for pH, bicarbonate, base excess, PaCO2 and TCO2 value showed high correlation (r > 0.9). Comparison of electrolyte and hematocrit between arterial and peripheral venous sample also showed high correlation (r > 0.9).Conclusion: Peripheral venous gas analysis for pH, bicarbonate, base excess, PCO2 and Electrolytes (Na+, K+) show good correlation with the respective arterial values. This result suggests that venous estimations can be an acceptable alternative to arterial measurements for managing critically ill patients.Bangladesh Crit Care J September 2016; 4 (2): 92-95

Base Balance

UNDERSTANDING BLOOD GAS values and acid-base balance are fundamental skills of neonatal nursing. This is because, in the NICU, blood gases are probably ordered more than any other laboratory test. The bedside nurse not only obtains the specimen, but is also crucially involved in interpreting the results because blood gases cannot stand alone; they need to be evaluated in the context of the entire clinical picture. This article provides basic information on the components of a blood gas, acid-base balance, as well as a systematic approach to blood gas analysis.

Introduction: Arterial blood gas (ABG) analysis is the gold standard method and frequently performed intervention to evaluate acid-base status along with adequacy of ventilation and oxygenation among patients with predominantly critical / acute diseases. Aims And Objectives: The aim of this study is to evaluate the correlation of VBG analysis and pulse oximetry (SpO2) with ABG analysis in critically ill patients. Materials And Methods:Intensive Care Unit (ICU), Command Hospital (Eastern Command), Kolkata, Adult patients requiring arterial blood gas analysis, JAN 2018 –JUNE 2019, 100 critically ill patients and Age – 18yrs and older, Sex – Either sex. Conclusion: In this study population of critically ill patients, pH and pCO2 on VBG analysis correlated with pH and pCO2 on ABG analysis. The SpO2 correlated well with pO2 on ABG analysis

Acid Base Disturbance

As part of arterial blood gas analysis, base excess is often reported as a measure of non-respiratory acid-base disturbance. Most blood gas analysers offer the option of calculating either the base excess of the blood sample or the base excess of the extracellular fluid (ECF). We report a case that illustrates that selecting the physiologically appropriate parameter avoids the potential for misinterpretation of acid-base data. We recommend that the base excess of the ECF is the appropriate metabolic blood gas parameter for clinical use.

Abstract Background: The superiority of either the traditional or Stewart based approach to acid-base balance has focused primarily on analyzing metabolic acidemia, with little attention given to patients with neutral pH. In this study, we evaluate metabolic disturbances in patients in the immediate postoperative period focusing on patients with neutral pH, while comparing the Stewart and traditional approach. Methods: We conducted a single center retrospective observational cohort study. Over a 17 month period, data on arterial blood gas analysis, electrolytes and albumin on the morning after surgery were retrieved from patients admitted to the postsurgical high dependency unit (HDU). Albumin corrected anion gap (AG), apparent (SIDa) and effective strong ion difference (SIDe) and strong ion gap (SIG) were calculated.Results: Out of 1207 HDU admissions, 400 cases had a complete set of laboratory-data including albumin of which 281 presented with neutral pH (7.35 ≤ pH ≤ 7.45), 64 with acidemia (pH < 7.35) and 55 with alkalemia (pH > 7.45). In pH neutral patients the following acidifying disturbances were found: SIDa was lowered in 101 (36%), SIG was raised in 60 (21%). Base excess (BE) was decreased in 16 (6%) and corrected AG raised in 107 (38%). The alkalizing effect of hypoalbuminemia was present in 137 (49%). Out of 134 cases with normal BE and corrected AG, SIDa was lowered in 58 (43%). Out of 136 cases with normal SIDa and SIG, none had lowered BE and 28 increased AG (21%). Length of stay was significantly longer in patients with hypoalbuminemia, lowered SIDa and increased corrected AG, but not decreased BE (Hypoalbuminemia: 16 days vs. 10 days, P < 0.001. Low SIDa: 15 days vs. 12 days, P = 0.015. Increased AG: 16 days vs. 11 days, P < 0.001. Low BE: 14 days vs. 13 days, P = 0.736).Conclusions: Metabolic disturbances, characterized mainly by the presence of lowered SIDa, increased AG and hypoalbuminemia, are frequent in our population with apparent neutral acid-base balance based on pH and base excess. These changes on the morning after surgery are associated with increased length of stay.
