Abstract

Abstract : Background: Epidural analgesia is commonly used for pain control after reconstructive hip surgery, but its use is controversial in the presence of an intrathecal baclofen pump (ITB). The purpose of this retrospective study was to investigate the rate of serious anesthetic and postoperative complications as well as the efficacy of epidural analgesia compared with lumbar plexus blocks (LPBs) for pain management after neuromuscular hip reconstruction in children with cerebral palsy (CP) and ITB. Methods: Pediatric patients with CP and ITB undergoing hip reconstructive surgery from 2010 to 2019 were retrospectively identified. Patients receiving epidural analgesia were compared with those receiving LPB. Morphine milligram equivalents per kilogram were used as a surrogate measure for pain-related outcomes, as pain scores were reported with wide ranges (eg, 0 to 5/10), making it unfeasible to compare them across the cohort. Postoperative complications were graded using the modified Clavien-Dindo classification. Results: Forty-four patients (26/44, 59% male) underwent surgery at an average age of 10.3 years (SD=3.4 y, range: 4 to 17 y). The majority utilized LPB (28/44, 64%) while the remaining utilized epidural (16/44, 36%). There were no differences in rates of serious complications, including no cases of ITB malfunction, damage, or infection. During the immediate postoperative course, patients who received LPB had higher morphine milligram equivalents per kilogram requirements than patients who received epidural analgesia. Conclusions: In patients with CP undergoing hip reconstruction surgery with an ITB in situ, epidural anesthesia was associated with improved analgesia compared with LPB analgesia, with a similar risk for adverse outcomes. Epidural catheters placed using image-guided insertion techniques can avoid damage to the ITB catheter while providing effective postoperative pain control without increasing rates of complications in this complex patient population. Level of Evidence: Level III.
