Abstract
BACKGROUND:: Intrathecal baclofen (ITB) is an effective therapy for spasticity and dystonia in pediatric populations; however, there are associated infectious complications. METHODS:: Patients who had an initial ITB device implanted at our center were followed to determine the proportion of patients with infectious and non-infectious complications, identify risk factors for infection and describe the clinical presentations, treatment and outcomes of infectious complications. RESULTS:: Over the 15 year study period, 139 patients had an initial ITB device placed. The mean age at placement was 13.6 years (range- 6 months to 41 years). In the first year of follow-up, 83% had no complications or secondary procedures, 17% had at least one secondary procedure and 5% had an infectious complication. The median time until infection was 14 days (mean 33 ± 42 days). Patients with secondary spasticity or dystonia were more likely to have infections than patients with cerebral palsy (86% vs.14%; p<0.0001). In the 94 patients with a first secondary procedure, 29% had at least one other procedure and 8% had an infection in the one year follow-up. Overall, 24 patients had 27 infections; 22% superficial, 33% deep and 45% organ space. Staphylococcus aureus was isolated in 50% of those with cultures obtained. Explantation was required in 59% of patients with an infection and differed by infection type: superficial (17%), deep (44%) and organ space (92%) (p=0.004). CONCLUSIONS:: Infectious complications were relatively uncommon; however, when present, frequently led to the explantation of the ITB pump device.
