[Pump-guided continuous subcutaneous opiate infusion for the treatment of the most severe pain].

The continuous subcutaneous infusion of opiate, a new approach to the alleviation of severe chronic pain, has been carried out using a pump system normally employed for the infusion of insulin. Relapses of pain can be controlled with bolus doses. This mode of application was compared with conventional therapy in 11 patients. All patients were free of pain during the continuous infusion, but none showed a satisfactory response during conventional treatment. The improved response under continuous opiate infusion was attained with much lower doses and thus with fewer side effects. The procedure is therefore highly effective and well tolerated.
