Abstract
OBJECTIVE: To investigate infection prevention by antibiotic-impregnated shunts (AIS) relative to conventional ones after pediatric hydrocephalus treatment. METHODS: This single center, retrospective analysis comprised 807 consecutive pediatric cases of hydrocephalus shunting performed by the same neurosurgeon between January 2001 and February 2013. Conventional and AIS catheters were used in 303 and 504 cases, respectively. Study outcomes were infection rates at 6 months (primary), and at 1 month and between 1 and 6 months (secondary). An infant (<1year) subgroup was also analyzed. RESULTS: The AIS relative to the conventional catheter group had significantly lower infection rates at 6 months (1.98% [10/504] vs. 5.95% [18/303], two-tailed p=0.0046; central nervous system: 60% and 55.56%; abdominal: 20% and 27.77%; wound: 20% and 16.67%, respectively) and 1 month (0.19% [1/504] vs. 2.65% [8/303], p=0.0023, respectively), but statistically similar rates between 1 and 6 months (1.79% [9/504] vs. 3.30% [10/303], p=0.2296, respectively). In the infant subgroup, AIS application was also associated with reduction in shunt infection (1.49% [7/470] vs. 3.76% [10/266], p=0.0489, respectively). CONCLUSION: AIS as compared to conventional catheter use appears to lower infection risk at 6 months, mainly during the first month, after hydrocephalus therapy in children. Copyright Â
