SummaryObjective: To describe the prevalence and possible causes of hypochloremia in the local hospital cat population. Material and methods: Retrospective study consisting of two parts. Data were collected from the local electronic medical records database using the search terms „chloride“ and „cats“ (part A), and „blood gas analysis“ and „cats“ (part B). The medical records of the hypochloremic cats were then reviewed to determine prior treatment or infusions and to identify major underlying disease processes. Part A included an age and gender matched non-hypochloremic control group, whereas in part B acid-base status was assessed. Results: Hypochloremia was detected in 367 (27%) of 1363 blood samples. The application of a correction formula to adjust for free water changes decreased the number of hypochloremic cats to 253 (19%). Only a minority had received glucocorticoids or loop diuretics and the prevalence of vomiting was 44%. Common associated disorders were gastrointestinal and respiratory diseases, as well as azotemia and diabetes mellitus. Polyuria/ polydipsia, dehydration, prednisolone or furosemide pretreatment, azotemia and diabetes mellitus increased, whereas fluid therapy and the diagnosis of neoplasia decreased the prevalence of hypochloremia. An inverse correlation was found between corrected chloride and standar dized base excess (rs = –0.597, p = 0.001) as well as anion gap (rs = –0.4, p = 0.026). 99% of the hypochloremic cats had derangements of acid-base balance. Conclusion: Hypochloremia is a common electrolyte disorder in the local cat population. The correction formula is ne cessary to adjust for changes in plasma osmolality. Although associated with metabolic alkalosis, most of the hypochloremic cats have a normal or decreased pH. The inverse correlation of chloride and anion gap als well as the high proportion of azotemic or diabetic animals support the concept of compensatory acidosis induced hypochlor emia. Clinical relevance: Hypochloremia should prompt the clinician to performe blood-gas analysis. Diabetes mellitus (especially ketoacidosis) and renal disease should be included in current algorithms for the evaluation of hypochloremic patients.

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.

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.
