["Terminal" dehydration, part 2 : Medical indications and therapeutic approach]

The approach in the clinical fluid management of the dying is still controversially discussed in specialist circles and also in the general population. In this article the importance of establishing the therapeutic indications is emphasized against the background of a lack of evidence. Options to achieve noninvasive objectification of assumed dehydration as well as assessment of the reversibility of the symptoms are shown and the importance of monitoring of all therapeutic actions is discussed. The pathophysiological foundation of reversible disorders of fluid homoeostasis are described and distinguished from the irreversible disorders leading to terminal dehydration. If clinically assisted hydration (CAH) is indicated, the hydration status must be assessed individually as well as in advance and all therapeutic measures must be constantly adjusted to the results of non-invasive monitoring procedures.
