Comparison of the effect of epidural versus intravenous patient controlled analgesia on inpatient and outpatient functional outcomes after adult degenerative scoliosis surgery: a comparative study.
BACKGROUND: Perioperative pain can negatively impact patient recovery after spine surgery and be a contributing factor to increased hospital length of stay and cost. Most data currently available is extrapolated from adolescent idiopathic cases and may not apply to adult and geriatric populations with thoracolumbar spine degeneration. PURPOSE: Study the impact of epidural analgesia on pain control and outcomes after adult degenerative scoliosis surgery in a large single-institution series of adult patients undergoing thoraco-lumbar-pelvic fusion. STUDY DESIGN/SETTING: Retrospective single-center review of prospectively collected data. PATIENT SAMPLE: Patients undergoing thoracolumbar fusion with pelvic fixation. OUTCOME MEASURES: Self-reported measures: Visual analog scale for pain. Physiologic Measures: Oral pain control requirements converted into daily morphine equivalents. Functional Measures: Ambulation perimeter after surgery, urinary retention and constipation rates. METHODS: We retrospectively reviewed patient data for the years 2016 and 2017 before the use of patient controlled epidural analgesia (PCEA), and then 2018 and 2019 after its implementation, for all thoracolumbar degenerative procedures, and compared their postoperative outcomes measures. RESULTS: There were 46 patients in the PCEA group and 37 patients in the intravenous PCA (IVPCA) groups. All patients underwent long segment posterolateral thoracolumbar spinal fusion with pelvic fixation. Patients in the PCEA group had lower pain scores and ambulated greater distances compared with those in the IVPCA group. PCEA patients also had lower urinary retention and constipation rates, but no increased intraoperative or postoperative complications related to catheter placement. CONCLUSIONS: PCEA can provide optimal pain control after adult degenerative scoliosis spine surgery, and may promote greater early ambulation, while decreasing postoperative constipation and urinary retention rates.
