Acid-base homeostasis is vital for the maintenance of normal tissue and organ function, as both acidosis and alkalosis can have harmful and potentially life-threatening effects. Arterial blood gas analysis, combined with routine clinical history and examination, can provide useful information for the management of the critically ill cardiac patient. Most acid-base derangements are reversed by treatment of the underlying disease process, rather than simple correction of the abnormal pH, and prognosis is determined by the nature of the underlying disease, rather than the extent of pH value deviation. Within this chapter, a six-step approach is presented for prompt and accurate acid-base interpretation. Water and electrolyte disorders are common in the intensive cardiac care unit, particularly in patients with cardiac failure. Prompt recognition and treatment is required to prevent cardiovascular and neurological compromise. Therapeutic strategies range from simple electrolyte substitution and fluid management to extracorporeal filtration of excess fluid and electrolytes. These are discussed within this chapter.

Base Balance

We performed a prospective study on the association between acid-base balance and asphyxta based on Apgar scores in 45 newborn babies admitted to the Division of Perinatology, Pirngadi Hospital, Medan, from January 1 to February 28, 1993. Blood gas analysis was done on blood obtained from umbilical artery. Based on 1st and 5th minutes Apgar scores, 40 (88.9%) and 21 babies (46.7%}, respectively, had asphyxia. Relation to acid-base balance was determined with the sensitivity of the 5th minute Apgar score in predicting acidotic states. It was found that Apgar score had sensitivity of 57.7% and specificity of 68.4% in predicting the acidotic states. Apgar score of > 7 was unable to. exclude the possible acidosis in 45% of cases (negative predictive value 54.1%). Gestational age had no influence on Apgar Scores. Apgar score was more sensitive to eliminate suspected acidosis in term neonates than in preterms. We recommend to perform umbilical arterial blood gas analysis to determine acidotic state in high risk newborn infants.

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.
