研究发现保守麻醉治疗腰痛可行

2015-03-02 王国彪 译 医学论坛网

一项新近的研究发现,腰椎间硬膜外注射局麻药(用或不用类固醇)为相当一部分患中央型椎管狭窄的病人提供福音。 在美国,腰痛是残疾的首要原因,腰椎管狭窄是继腰椎间盘突出症和退行性腰椎滑脱症之后,作为腰腿疼需要手术的第三大需求之一,其治疗方法包括药物治疗和椎管减压的外科手术。硬膜外注射是治疗中央椎管狭窄常用的非手术干预措施之一,然而,目前有关硬膜外注射治疗中央椎管狭窄疗效的文献却很缺乏。

一项新近的研究发现,腰椎间硬膜外注射局麻药(用或不用类固醇)为相当一部分患中央型椎管狭窄的病人提供福音。

在美国,腰痛是残疾的首要原因,腰椎管狭窄是继腰椎间盘突出症和退行性腰椎滑脱症之后,作为腰腿疼需要手术的第三大需求之一,其治疗方法包括药物治疗和椎管减压的外科手术。硬膜外注射是治疗中央椎管狭窄常用的非手术干预措施之一,然而,目前有关硬膜外注射治疗中央椎管狭窄疗效的文献却很缺乏。

基于此,研究者评估了硬膜外注射(用或不用类固醇)持续长久缓解疼痛(中央腰椎狭窄相关的腰背和下肢疼痛)和改善功能状态的疗效。

在随机双盲主动对照试验设计中,纳入120例患者,分为两组。Ⅰ组患者局麻药(0.5%利多卡因)6ml硬膜外注射,Ⅱ组局麻药(0.5%利多卡因)5ml加1ml类固醇和6mg倍他米松混合硬膜外注射。评估结果采用治疗3,、6、12、18、24个月后的数字疼痛评分量表(NRS)和Oswestry功能障碍指数(ODI)。主要测量结果显著改善,定义为疼痛和功能障碍评分提高50%。

结果为,两年结束后明显缓解和改善功能状态在Ⅰ组和Ⅱ组所有患者中的比例分别为72%和73%,而成功治疗结束后比例为84%和85%。达到明显改善的时间Ⅰ组为65.7±37.3周,Ⅱ组为68.9±37.7周,而被分为成功组的时间分别为77±27.8周和77.9±30.2周。两组治疗过程平均相差5-6周。
