Site of catheter insertion in burn patients and infection: a systematic review

Abstract

The aim of the study was to conduct a systematic review to identify and appraise the evidence on possible association of the site of venous catheter insertion in burn patients and an increased occurrence of catheter-related infection. Searches were performed in MEDLINE, LILACS, CINAHL, EMBASE, Web of Science and The Cochrane Library. Nine studies were selected for the review; four of them mentioned, directly or indirectly, an association between catheter-related infection and the insertion of the catheter either in the burn wound or in surrounding area, and five studies investigated the occurrence of infection related to both the catheter and the anatomical sites of catheter insertion. Higher infection rates occurred when the catheters were inserted directly in the burn wound or near the wound (level of evidence IV) or in the femoral vein (level of evidence IV). No significant differences in infection occurrence rates were observed between central catheters and peripherally inserted central catheter (level of evidence IV). Further investigations for techniques and types of coverage of venous catheter insertion dressings are important for preventing infection in burn patients. Also, new technologies for venous access must be evaluated.
