EFICÁCIA DAS COBERTURAS EM ÓSTIO DE CATETER VENOSO CENTRAL NA PREVENÇÃO DE INFECÇÃO: REVISÃO SISTEMÁTICA.

Abstract

Central venous catheters are very important devices in critically ill patients care. However, this device can become a threat to the health of patients, as commonly causes bloodstream infections, especially those most vulnerable. The aim of the study was to evaluate the effectiveness of chlorhexidine-impregnated coatings in central venous catheter ostium in reducing the incidence of catheter-related bloodstream infection. The method used was a systematic review study in a timeframe of eleven years, including the research published in the period from 2004 to 2014, including publications on coatings of central venous catheter ostium in the perspective of the prevention and control of infection, in search of evidences about the effectiveness of using chlorhexidine-impregnated coatings when compared to others coatings in reducing rates of catheter-related bloodstream infection. The search for articles was made through the CINAHL databases, Web of Science, EMBASE, LILACS, MEDLINE and PubMed, using the descriptors and relevant terms to each one. Seventy six publications were identified and eight fulfilled the eligibility criteria. Participants in the studies ranged from 85 to 2302 patients. The use of chlorhexidine-impregnated coating was related to the reduction of the catheterrelated infection rates and catheter-related bloodstream infection rates. The coating with chlorhexidine was well tolerated by participants, however, local reactions such as hyperemia, dermatitis and skin maceration were reported, especially in patients with multiple organ failure, subcutaneous edema or skin integrity impaired, and when remained without dressing change for more than three days. The chlorhexidineimpregnated coating presented advantages and reduction in catheter-related infection rates and in catheter-related bloodstream infection rates when compared to coating without antiseptics, besides representing a best cost-benefit ratio and reduction in mortality rate.
