Abstract
AbstractBackgroundCentral line–associated bloodstream infections are a major concern for children with intestinal failure and in animal research using parenteral nutrition (PN). In neonatal piglets receiving PN, we compared sepsis, line occlusions, line replacements, mortality, and costs with and without the use of a 4%‐tetrasodium ethylenediaminetetraacetic acid (T‐EDTA) locking solution.MethodsWe performed a retrospective review of piglets with a central venous jugular catheter enrolled in 14‐day exclusive PN (TPN) trials or in 7‐day short bowel syndrome (SBS) trials, before and after initiation of T‐EDTA. Lines were locked with a 1‐ml solution for 2 h daily (T‐EDTATPN, n = 17; T‐EDTASBS, n = 48) and compared with our prior standard of care using 1.5‐ml heparin flushes twice daily (CONTPN, n = 34; CONSBS, n = 48). Line patency and signs of sepsis were checked twice daily. Jugular catheters were replaced for occlusions whenever possible. Humane end points were used for sepsis not responding to antibiotic treatment or unresolved catheter occlusions.ResultsCompared with CON, sepsis was reduced using T‐EDTA, significantly for TPN (P = 0.006) and with a trend for SBS piglets (P = 0.059). Line occlusions necessitating line changes were reduced 15% in TPN studies (P = 0.16), and no line occlusions occurred for T‐EDTA SBS piglets.ConclusionIn our neonatal piglet research, use of T‐EDTA locking solution decreased sepsis and, although not statistically significant, reduced occlusions requiring line replacements. Given the expense of animal research, adding a locking solution must be cost‐effective, and we were able to show that T‐EDTA significantly reduced total research costs and improved animal welfare.
