    • "A decade later, in a rat model of massive haemorrhage, resuscitation with red blood cells and Ringer's lactate solution produced a significantly better acid-base balance and significantly greater 2-week survival than resuscitation with red blood cells and 0.9% saline [77]. The hyperchloraemic acidosis seen with 0.9% saline resuscitation has also been highlighted as an easily preventable iatrogenic cause of acidosis in trauma resuscitation [78]. "

    ABSTRACT: Chloride is the principal anion in the extracellular fluid and is the second main contributor to plasma tonicity. Its concentration is frequently abnormal in intensive care unit patients, often as a consequence of fluid therapy. Yet chloride has received less attention than any other ion in the critical care literature. New insights into its physiological roles have emerged together with progress in understanding the structures and functions of chloride channels. In clinical practice, interest in a physicochemical approach to acid-base physiology has directed renewed attention to chloride as a major determinant of acid-base status. It has also indirectly helped to generate interest in other possible effects of disorders of chloraemia. The present review summarizes key aspects of chloride physiology, including its channels, as well as the clinical relevance of disorders of chloraemia. The paper also highlights current knowledge on the impact of different types of intravenous fluids on chloride concentration and the potential effects of such changes on organ physiology. Finally, the review examines the potential intensive care unit practice implications of a better understanding of chloride.
