Safe drug therapy in clinical practice: experience of using microinfusion single-use mechanical systems in treatment of patients with malignant diseases of hematopoietic tissue and solid tumors

Recently due to significant successes in drug therapy of malignant tumors, the question of quality of life of patients has become more important. Cyclical drug treatment implies intravenous infusion of antitumor agents. Complications associated with this type of therapy include phlebitis and extravasation and, in some cases, lead to full obliteration of vessel lumen and vast skin and hypoderm necrosis. Multiple venous punctions can with time lead to significant technical difficulties in accessing the vein and limit the continuation of therapy. This drives the necessity to search for rational approaches to patient safety during both outpatient and inpatient antitumor drug treatment. To solve this problem, fully implanted venous port systems were developed and implemented in clinical practice which provide organization of aseptic continuous venous access, as well as infusion pumps (for independent prolonged intravenous therapy). Use of these devices allows for continuity and cycling of treatment process, significantly improves patients' quality of life by not limiting daily activities.In the article we present our experience of using microinfusion single-use mechanical systems for antitumor drug therapy and relief of intense pain syndrome in patients with malignant disorders of hematopoietic tissue and solid tumors.
