    IntroductionSpasticity is a complex problem in patients with neurological disorders and may distress their quality of life. Intrathecal baclofen infusion pumps reduce spasticity with low doses and minimal side effects but are not free from complications. We aimed to evaluate the efficacy and safety of intrathecal baclofen infusion pumps as well as patients' satisfaction.Material And MethodsRetrospective cohort study including all intrathecal baclofen infusion pumps placed up to December 2015. Demographic characteristics, clinical diagnoses, date of placement or withdrawal/replacement of intrathecal baclofen infusion pumps, baclofen dosage and complications of intrathecal baclofen infusion pumps were collected. Assessments from the Ashworth and Penn's scales, Katz index and patients' global satisfaction were analysed.ResultsIn 19 years we placed 251 intrathecal baclofen infusion pumps in 155 patients. The mean age was 41.1 ± 15.8 years. The most frequent conditions were: trauma (34%), cerebral palsy (14%), multiple sclerosis (12%) and stroke (12%). Eighty-five patients (55%) required a second pump, and eleven (7%) a third one. The lifetime of the first pump was 72 (36 - 89) and the total follow-up time was 96 (9 - 132) months. The causes of withdrawal/replacement were: battery failure (57%), catheter migration/kinking (24%), infection (14%) and pump displacement/exteriorization (7%). The complication rate was 0.21 events/month. There was a significant improvement in the Ashworth and Penn's scales after the placemen of intrathecal baclofen infusion pumps (p < 0.001 for all diagnoses) and the patients were satisfied with the treatment.DiscussionThe incidence of complications was within range of other international studies despite our long follow-up time. Events per month, loss to follow-up, re-intervention rate, incidence of infection and mortality were similar to other studies.ConclusionIntrathecal baclofen infusion pumps are safe and effective in the treatment of spasticity. Infusion pumps provide a high level of satisfaction regarding treatment and quality of life.
