Abstract

Prophylactic ethanol lock therapy (ELT) reduces central line-associated bloodstream infections (CLA-BSIs) in children with intestinal failure (IF). However, the risk of associated complications is unclear. We aim to describe our experience with prophylactic ethanol locks in a cohort of patients with IF. Thirty patients on ELT from 2010-2013 were identified by review of our intestinal rehabilitation registry. Patient demographics, CLA-BSI events, and line complications were extracted. Comparisons in infection and complication rates when on and off ELT were made using a Poisson mixed-effect regression model. CLA-BSIs when on and off ELT were 3.1 and 5.5 per 1000 catheter days, respectively (P <015). Overall complication rates were similar in both groups. In those patients who experienced a complication, the complication rates on ELT compared with time off ELT were significantly lower (P <003). Line perforation or breakage rates declined significantly when on ELT, from 1.8 to 1.53 per 1000 catheter days (P <006). Line occlusion rates also decreased on ELT, from 0.6 to 0.3 per 1000 catheter days (P =056). Infecting organisms were not different on and off ELT, and patients experienced a similar number of polymicrobial infections on or off therapy. Klebsiella pneumoniae was the most common infecting organism in both groups. Ethanol lock therapy use reduces both CLA-BSI and central line complication rates in children with IF. These results underscore the safety and efficacy of ELT use in this population.
