RESUMEN
BACKGROUND: Children with cerebral palsy often suffer from increased tone, which can be treated with intrathecal baclofen via implanted pump. Additionally, they often require major orthopedic surgery for hip reconstruction; however, the presence of an intrathecal baclofen pump is a relative contraindication to regional anesthesia due to concerns about damaging the intrathecal baclofen pump system. AIMS: (a) To evaluate adverse events related to placing epidural catheters in children with intrathecal baclofen pumps and (b) describe our multidisciplinary approach to the care of these complex patients. METHODS: Children with cerebral palsy and intrathecal baclofen pump in situ who underwent hip reconstruction between 2010 and 2019 and had a perioperative epidural placed were reviewed retrospectively. Charts were assessed for adverse events or intrathecal baclofen complications. Fluoroscopic images were reviewed to evaluate the proximity between epidural and intrathecal baclofen catheters. The process of coordinating multiple services was examined. RESULTS: Sixteen children met the inclusion criteria. There were no major complications following epidural placement. Postoperative pump interrogation was normal for all patients. Fluoroscopy was utilized for 9/16 (56%) epidural procedures. Epidurogram was used to confirm 11/16 catheters (68%). Children with an intrathecal baclofen pump were identified by orthopedic surgeons at the time of surgical booking and referred to the regional anesthesia team for review. The neurosurgical, pain, and regional anesthesia teams determined the appropriateness and safety of approaching the neuraxis. Pain and/or regional anesthesiologists with competency in spine fluoroscopy were scheduled on the day of surgery for fluoroscopically guided epidural placement. Postoperatively, catheters were managed by the acute pain team. Intrathecal baclofen pumps were interrogated by the baclofen pump team prior to patient discharge. DISCUSSION: In this case series, not only was epidural placement feasible but also there were no observed complications. This work highlights the importance of a multidisciplinary approach to complex regional anesthetic techniques, as well as the importance of basic competency in spine fluoroscopy for regional anesthesiologists.
