Episode 403: 411. Gabapentin and Emergency Carotid Artery Stenting in Stroke
Study Summary: Emergent Carotid Stenting in Acute Stroke ThrombectomyA multicenter registry study in Catalonia (2017–2023) evaluated outcomes in 578 patients with acute ischemic stroke and tandem lesions (large-vessel occlusion plus extracranial carotid stenosis). Patients were divided into two groups: those who received emergent carotid artery stenting (E-CAS) and those who did not (non-CAS).Key Findings:Favorable outcomes (modified Rankin Scale 0–2) were more common in the E-CAS group at:90 days: 46% vs. 37%1 year: Odds ratio 1.35Recanalization rates were higher with E-CAS: 92% vs. 73%No significant differences in:Hemorrhagic transformation at 36 hours (though a trend toward higher rates with E-CAS)1-year mortalityConclusion:Emergent carotid stenting during thrombectomy may improve functional outcomes and recanalization without significantly increasing bleeding or mortality. However, as this was not a randomized trial, results should be interpreted cautiously. Further randomized studies are needed. Ezcurra-Díaz G et al.

Gabapentinoids for Postoperative Pain: No Benefit FoundStudy Overview: A large randomized, placebo-controlled trial in the U.K. (GAP study) evaluated the effectiveness of gabapentin for postoperative pain in 1,200 patients undergoing various cardiac, thoracic, and abdominal surgeries.Intervention:Gabapentin group: 600 mg pre-op, then 300 mg twice daily for 2 days post-opControl group: PlaceboKey Findings:Slight pain reduction at 1 hour post-op (4.0 vs. 3.5 on 11-point scale)No difference in pain at later time pointsNo differences in:Opioid useSerious adverse eventsLength of hospital stayCommentary: Despite widespread off-label use, this large, well-designed trial found no meaningful benefit of gabapentin for postoperative pain. While short-term use appeared safe, prolonged use may pose risks (e.g., sedation, falls, respiratory depression). Clinicians are advised to reconsider routine perioperative use of gabapentinoids.
