患者,中年,脊椎间盘破裂,髓质流出,严重炎症反应,一侧腿部及臀部疼痛,卧床,行动极为困难,上下床以及行走5米距离都疼痛,很困难。遵医嘱每天服用止疼消炎药。后来病情发展,即使严格卧床休息,患侧大小腿和臀部几乎每天抽筋,难以忍受,服用镁片无效。我提议用尼古丁贴片 (nicotine patch) 缓解抽筋。患者接受建议。取市售尼古丁贴片(Clear NicoDerm, 14mg), 剪成小片,大小尺寸~9mm x 6 mm,每片约含尼古丁~ 0.5mg (注:抽一支烟约吸入1mg 左右的尼古丁)。贴在腿及臀部痉挛部位,每个痉挛部位一小片。通常3~4片/1~2天。一般1分钟以后痉挛开始缓解,约5分钟后痉挛消失,对解除痛苦,和不得不进行的活动有很多帮助。后得知患者用尼古丁贴片处理方法进行了数周,始终有效。无尼古丁上瘾现象。
我认为,根据诸多文献,作用机理在于尼古丁增强交感神经功能,扩张小血管,增加血流,改善局部循环,进而解除痉挛。
