不同时间窗高压氧治疗对脊髓损伤患者疗效的影响

目的 观察不同时间窗高压氧治疗对脊髓损伤(SCI)患者疗效的影响.方法 共选取284例SCI患者,将其随机分为高压氧治疗组(HBO组)及对照组.2组均给予常规处理(包括脱水剂、神经营养药物、康复训练、针灸以及对症支持治疗等),HBO组患者在此基础上于不同时间窗(SCI发生8 h以内、8 h～1 d、1 d～1周、1周以上)分别辅以HBO治疗.于治疗前、治疗3个月后分别采用美国脊髓损伤协会(ASIA)评分及Barthel指数对患者脊髓功能及日常生活活动(ADL)能力进行评定.结果 在SCI发生8 h内开始治疗,2组患者脊髓感觉、运动功能及ADL能力均较治疗前显著改善(P＜0.01),2组间疗效差异无统计学意义(P＞0.05);在SCI发病24 h内或1周内开始治疗,2组患者脊髓功能、ADL能力亦较治疗前获得一定程度改善(P＜0.05),但均明显不及发病8 h内开始治疗的患者(P＜0.05);且此时HBO组疗效显著优于对照组(P＜0.05);在SCI发病1周后开始治疗,发现2组患者脊髓功能及ADL能力均无明显改善(P＞0.05).结论 于SCI发病早期(＜8 h)辅以HBO治疗,能显著改善患者脊髓功能及ADL能力,其疗效明显优于其它时间窗治疗.

Therapeutic window for the use of hyperbaric oxygen therapy in patients with spinal cord injury

Objective To compare the therapeutic effects of hyperbaric oxygen (HBO) therapy at different time points on patients with spinal cord injury. Methods A total of 284 cases of spinal cord injury (SCI) were divided into an HBO group and a control group. The control group was treated with routine interventions (including a dehydrator, medication for neurotrophy, rehabilitation management, acupuncture and supportive treatment). The HBO group was treated with HBO in addition to the routine treatments, initiated at different time points after onset of SCI ( from less than 8 hours to longer than 1 week). All of the patients were evaluated in terms of scores on the American Spinal Cord Injury Association (ASIA) assessment and Barthel's index (BI) before and after treatment.Results Both groups had excellent effects when the treatment was initiated within the first 8 hours after the onset of SCI. There was no significant difference between the two groups. Average ASIA and BI scores in both groups improved significantly within the first 24 hours, and over the 1 st week after the onset of SCI. The recovery of neurological function and ability in the activities of daily living (ADL) was significantly better when HBO treatment was initiated within 8 hours after SCI compared with that initiated after 24 hour and 1 week. The therapeutic effects in the HBO group patients were significantly better than in the control group when HBO was initiated at 8 and 24 hours after onset of SCI. Neither the HBO group nor the control group had significant further improvement in ASIA scores or ADL performance when treatments initiated after 1 week. Conclusions HBO can significantly improve neurological function and ADL performance after SCI if it is administered within 1-8 hours.
