Does a Dedicated Lumen for Parenteral Nutrition Administration Reduce the Risk of Catheter-Related Bloodstream Infections? A Systematic Literature Review

Abstract

Guidelines recommend using single-lumen central vascular access devices (CVADs) for the administration of parenteral nutrition (PN) or lipid-based solutions, or a dedicated lumen on a multilumen CVAD. Publications reviewed by the authors reported comparative rates of catheter-related bloodstream infection (CR-BSI) in patients with CVADs who received PN through a dedicated lumen compared with those who had PN administered through multilumen CVADs. Two studies included 650 patients with 1349 CVADs. CR-BSIs were equally distributed between the 2 groups. Both studies were poorly reported and had significant risk of bias. These results should be interpreted with caution.
