As a consequence of underlying diseases and therapeutic manipulations, surgical patients may develop potentially harmful disorders of acid–base equilibrium, intravascular and extravascular volume, and serum electrolytes (Prough DS, Funston JS, Svensen CH, Wolf SW. Fluids, electrolytes, and acid-base physiology. In: Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Ortega R, Stock MC, eds. Clinical Anesthesia. Philadelphia: Lippincott Williams & Wilkins; 2013: 327–361). Precise management of acid–base status, fluids, and electrolytes may limit perioperative morbidity and mortality.
