[Hypodermoclysis, a neglected approach]

Patients with advanced cancer frequently present with chronic nausea, emesis, bowel obstruction, confusional syndromes or dysphagia. All these conditions make it difficult for the patient to take oral medications or to maintain an adequate level of hydration by mouth. Hypodermoclysis is a safe and simple method that allows for cost-effective sucutaneous delivery of fluids and drugs. Hypodermoclysis has some clearcut advantages over the i.v. route. It can be started without need for a physician or a nurse, does not immobilize a limb, can be stopped and restarted at any moment without concern for clotting, and its use sparses nursing time. It also allows for easier and safer home discharge. Potentiel side effects of hypodermoclysis include pain at infusion site, sloughing tissues as a result of insufficient fluid absorption, infection, and puncture of vessels with bleeding. This paper gives some guidelines for the use of hypodermoclysis for fluid, electrolytes and drugs frequently used in a palliative care setting. The controversy surrounding the treatment of dehydration in the terminally ili is also briefly examined.
