Aseptic non-touch technique and catheter-related bloodstream infection in children receiving parenteral nutrition at home.

ABSTRACT: OBJECTIVES: Parenteral nutrition (PN) at home is an acceptable form of delivering long-term PN for children with intestinal failure. Catheter-related bloodstream infection (CRBSI) is one of the serious complications of long-term PN and can lead to increasing morbidity and mortality. Using aseptic non-touch technique (ANTT) was proven to decrease the incidence of CRBSI in hospital patients. In this study we aimed to review the incidence of CRBSI in children receiving PN at home in our institution using the ANTT and a simplified training programme for parents and carers. METHODS: We retrospectively collected clinical and microbiological data on all children with intestinal failure (IF) who were on treatment with PN at home under our specialist IF rehabilitation service between November 2012 and November 2013. RESULTS: Thirty-five children were included, 16 of whom did not have any infection recorded during the study period. The overall CRBSI rate was 1.3 infections per 1000 line-days, with Staphylococcus being the commonest organism. Twenty-one children did not require catheter change and the overall catheter changes were 1.8 per 1000 line-days. CONCLUSION: In this article, we report a low incidence of CRBSI in a single institution by using the principle of ANTT for accessing central venous catheters combined with a simplified, nurse-led, two-week standardised training programme for parents of children going home on PN.

Project description:Manganese, an essential metal for normal growth and development, is neurotoxic on excessive exposure. Standard trace element-supplemented neonatal parenteral nutrition (PN) has a high manganese content and bypasses normal gastrointestinal absorptive control mechanisms, which places infants at risk of manganese neurotoxicity. Magnetic resonance (MR) relaxometry demonstrating short T1 relaxation time (T1R) in the basal ganglia reflects excessive brain manganese accumulation.This study tested the hypothesis that infants with greater parenteral manganese exposure have higher brain manganese accumulation, as measured by MR imaging, than do infants with lower parenteral manganese exposure.Infants exposed to parenteral manganese were enrolled in a prospective cohort study. Infants classified as having high manganese exposure received >75% of their nutrition in the preceding 4 wk as PN. All others were classified as having low exposure. Daily parenteral and enteral manganese intakes were calculated. Whole-blood manganese was measured by high-resolution inductively coupled plasma mass spectrometry. Brain MR relaxometry was interpreted by a masked reviewer. Linear regression models, adjusted for gestational age (GA) at birth, estimated the association of relaxometry indexes with total and parenteral manganese exposures.Seventy-three infants were enrolled. High-quality MR images were available for 58 infants, 39 with high and 19 with low manganese exposure. Four infants with a high exposure had blood manganese concentrations >30 ?g/L. After controlling for GA, higher parenteral and total manganese intakes were associated with a lower T1R (P = 0.01) in the globus pallidus and putamen but were not associated with whole-blood manganese (range: 3.6-56.6 ?g/L). Elevated conjugated bilirubin magnified the association between parenteral manganese and decreasing T1R.A short T1R for GA identifies infants at risk of increased brain manganese deposition associated with PN solutions commonly used to nourish critically ill infants. These trials were registered at clinicaltrials.gov as NCT00392977 and NCT00392730.
