Background and Objectives: Catheter-related bloodstream infections (CRBSIs) are one of the most severe complications in children with intestinal failure (IF) who require long-term parenteral nutrition (PN). Taurolidine-citrate solution (TCS), with proven antimicrobial and antibiofilm properties, has been proposed as a promising alternative to heparin locks for preventing infection. The aim is to evaluate the efficacy and safety of the TCS in reducing the rates of CRBSI and pathogen-specific infections in pediatric patients with indwelling central venous catheters (CVCs) who are receiving PN. Materials and Methods: This retrospective study included 48 pediatric IF patients treated at an intestinal rehabilitation and transplantation center in T & uuml;rkiye. Patients received either TCS or heparinized saline (0.9% saline solution containing 100 IU of heparin) as a catheter lock. Infection data were extracted from medical records and expressed as events per 1000 catheter days. Group comparisons were performed using non-parametric tests, and Poisson regression was applied to calculate rate ratios (RRs) and 95% confidence intervals (CIs). Adjusted rate ratios were obtained from a Poisson regression model that included the following variables: age, sex, diagnosis category, ostomy status, catheter type, and follow-up duration. Log(catheter-days) was incorporated as an offset term. Overdispersion was assessed and not detected. Results: The crude CRBSI rate was lower in the TCS group than in the heparinized saline group (29.4 vs. 42.8 per 1000 catheter days), though this difference was not statistically significant (p = 0.383). However, after adjustment by Poisson regression, TCS use was significantly associated with reduced infection rates (adjusted RR = 0.78, 95% CI = 0.70-0.87, p < 0.001). TCS use was also significantly associated with reduced rates of Gram-positive (RR = 0.78, p = 0.006), Gram-negative (RR = 0.48, p < 0.001) and fungal (RR = 0.63, p < 0.001) infections. No adverse events were observed among the TCS group. Conclusions: Standardized TCS lock therapy effectively and safely reduces CRBSIs in pediatric patients with IF, particularly those caused by Gram-negative and fungal organisms. These results support the use of TCS as a prophylactic option for preventing infection in long-term CVC use.
