Hypodermoclysis

Hypodermoclysis, which can also be called interstitial infusion or subcutaneous infusion, is the subcutaneous administration of fluids to the body, often saline or glucose solutions.Hypodermoclysis can be used where a slow rate of fluid uptake is required compared to intravenous infusion. Typically, it is limited to 1 ml per minute, although it is possible to increase this by using two sites simultaneously. [Source: Wikipedia ]
