Strategies for preventing obstruction in central catheters fully implanted in oncological patients

Abstract

Objective: To analyze scientific productions that address prevention and care strategies in the obstruction of central venous catheters that are fully implanted in cancer patients. Material and Method: This is an integrative literature review, which took place on the MEDLINE, LILACS, CINAHL and EMBASE databases, from 20 July 2019 to 31 July 2019, using as descriptors: Central venous catheterization; Catheter obstruction and Oncology, in addition to the use of free terms: Catheter fully implanted and Neoplasia. Results: In total, 10 studies were selected and included. After the analysis, the following analysis categories emerged: Strategies for preventing obstruction in CVC-TI and Care established in clearing the CVC-TI; having as main subjects approached: the comparison between the effectiveness in the use of heparin and saline solution for maintenance and time interval between them; unblocking methods and permeability assessment of CVC-TI. Conclusion: Despite the emergence of new possible ways of preventing obstruction and care strategies for clearing CVC-TI, the literature does not have a consensus on the use of solutions with or without heparin and the time interval between maintenance for the effectiveness of the permeability of these devices in cancer patients.
