limited to 1 ml per minute, although it is possible to increase this by using two sites simultaneously. The chief advantages of subcutaneous infusion over intravenous infusion is that it is cheap and can be administered by non-medical personnel with minimal supervision. It is therefore particularly suitable for home care. The enzyme hyaluronidase can be added to the fluid to improve absorption during the infusion. Subcutaneous infusion can be speeded up by applying it to multiple sites simultaneously. The technique was pioneered by Evan O'Neill Kane in 1900. Kane was looking for a technique that was as fast as intravenous infusion but not so risky to use on trauma patients in unhygienic conditions in the field.
