Administration of intravenous fluids is the most common therapy given to patients admitted to a hospital. Evidence suggests that the use of normal saline (NS) in large quantities is not without adverse effects. Balanced salt solutions (BSS) contain bicarbonate or one of its precursors that act as a buffer, and the electrolyte composition resembles that of plasma. ⋯ In surgical patients, studies found only transient hyperchloraemia and increase in the base deficit in patients receiving NS. Systematic reviews and meta-analyses did not find any significant differences in adverse outcomes such as the need for renal replacement therapy or mortality with the use of saline; however, blood chloride levels were consistently higher with saline compared to BSS. There is a need for larger trials with better methodology to determine if the physiological benefits of BSS translate into better clinical outcomes.
