Subcutaneous fluid administration and the hydration of older people

Hypodermoclysis, or the subcutaneous administration of fluids, is a method of rehydration that is not routinely used in the UK. Yet it is a simple and effective method of fluid administration for individuals with mild-to-moderate dehydration, especially for the frail and elderly (Sasson and Shvartzman, 2001). Subcutaneous infusion is an alternative route of parenteral administration. It provides a number of advantages over the intravenous route for those individuals unable to tolerate enteral fluids, as it is associated with fewer complications, as well as a wider range of infusion sites. This makes it particularly advantageous for frail and/or older patients requiring low-volume hydration in the community setting. This article discusses indications and contraindications for subcutaneous infusions, as well as patient assessment, placement, securement and potential complications.
