Abstract：
OBJECTIVE: Chronic pain is a common symptom experienced by patients after spontaneous epidural hematoma (SSEH), and it seriously affects their quality of life. The outcome and prognosis of chronic pain after SSEH are rarely reported. Thus, we conduct this study to present the outcomes and explore prognostic factors of chronic pain in patients with SSEH.
METHODS: We retrospectively reviewed patients diagnosed with SSEH and invited them to complete the American Spinal Injury Association (ASIA) and Neuropathic Pain Symptom Inventory (NPSI) scales. Pearson χ2 and binary logistic regression were used to explore prognostic factors related to chronic pain after SSEH.
RESULTS: A total of 55 patients were reviewed; 21 patients (38.2%) were lost to follow-up, 3 patients (5.4%) died, and 31 patients (56.4%) completed the scales, with a mean follow-up time of 20.6 ± 17.3 months. The ASIA and NPSI results showed significant improvement after surgery. Pearson χ2 showed that timely surgery (≤ 12 h) was related to better outcomes (p < 0.05, Fisher test), and binary logistic regression revealed that patients with a preoperative NPSI score of 11-20 were prone to achieving significant pain relief (OR 23.67, 95%CI 1.11-503.48, p = 0.04).
CONCLUSIONS: Chronic pain is a common symptom during follow-up after SSEH, and timely intervention is suggested to obtain satisfactory outcomes. Patients who receive emergent surgery within 12 h or who have a preoperative NPSI score of 11-20 may achieve significant relief of chronic pain.

摘要：
目的：慢性疼痛是自发性硬膜外血肿（SSEH）后患者的常见症状，严重影响他们的生活质量。SSEH术后慢性疼痛的转归和预后鲜有报道。因此，本研究旨在介绍SSEH患者慢性疼痛的结局并探讨其预后因素.
方法：我们回顾性回顾了诊断为SSEH的患者，并邀请他们完成美国脊髓损伤协会（ASIA）和神经性疼痛症状量表（NPSI）量表。采用Pearsonχ2和二元logistic回归分析探讨SSEH术后慢性疼痛的相关预后因素。
结果：共检查55例患者；21例患者（38.2%）失访，3例（5.4%）死亡，31例(56.4%)患者完成量表,平均随访时间为20.6±17.3个月。ASIA和NPSI结果显示手术后明显改善。Pearsonχ2显示，及时手术（≤12h）与更好的结局相关（p<0.05，Fisher检验），和二元逻辑回归显示，术前NPSI评分为11-20分的患者易于实现明显的疼痛缓解（OR23.67，95CI1.11-503.48，p=0.04）。
结论：慢性疼痛是SSEH术后随访期间的常见症状，建议及时干预以获得满意的结果。在12小时内接受紧急手术或术前NPSI评分为11-20的患者可以显着缓解慢性疼痛。
