[Infusion pumps and subcutaneously implantable catheter systems as an aid in the ambulatory care of tumor patients].

Totally implantable catheters have greatly improved therapy and supportive care of tumor patients. Venous catheters can reduce the problem of maintaining reliable vascular access and the risk of cytotoxic drug extravasation. In addition, epidural or intrathecal catheter systems can result in an improved pain relief and in reduced side effect incidences in many patients suffering from severe cancer pain. The intraarterial and intraperitoneal catheters facilitate loco-regional chemotherapy. If used by an experienced team, most of these systems have a relatively low complication rate. The combination of such catheters with portable pumps does further facilitate the management of ambulatory tumor patients and will improve their quality of life.
