SIR 2016:冷冻治疗幻肢痛有奇效

2016-04-10 QQduhp 译 MedSci原创

许多接受截肢手术的民众经常觉得截肢部位出现如刺痛、痉挛痛、热、冷等感觉。这时,不要存在你拥有完整四肢的幻想,也不要以为疼痛可以根治。研究人员们指出他们发现了一种冷冻技术可减轻幻肢痛(PLP)和其他痛苦的感觉,他们在介入放射学协会年度会议上提出该结论。 埃默里大学研究人员发现,使用冷风治疗可以显著降低幻肢痛患者的慢性疼痛感。他们将此命名为冷冻消融术或极端寒冷法,主要是通过将患肢末端神经和疤痕组织冷冻

许多接受截肢手术的民众经常觉得截肢部位出现如刺痛、痉挛痛、热、冷等感觉。这时,不要存在你拥有完整四肢的幻想,也不要以为疼痛可以根治。研究人员们指出他们发现了一种冷冻技术可减轻幻肢痛(PLP)和其他痛苦感觉,他们在介入放射学协会年度会议上提出了该结论。
  
埃默里大学研究人员发现,使用冷风治疗可以显著降低幻肢痛患者的慢性疼痛感。他们将此命名为冷冻消融术或极端寒冷法,主要是通过将患肢末端神经和疤痕组织冷冻封闭起来,阻断神经信号通路,达到减轻患者疼痛的目的。 

CDC指出,美国每年约有185000人需要接受截肢术,且接受截肢手术的大多为战争中受伤的军人或糖尿病足患者。研究人员希望通过这种冷冻技术可减轻PLP患者的疼痛感,同时有助于从战场退伍的军人更好地回归社会,并提高他们的生存质量。

埃默里大学医学院介入放射学副教授David Prologo指出,曾经历过越南战争并受伤退伍的军人仍然存在幻肢痛,直到现在他们的痛苦也没有减少。
  
为了评估PLP患者使用冷冻消融术治疗的安全性和有效性,研究人员进行了一项临床试验,名为“对难治性幻肢疼痛经皮进行冷冻消融术治疗”的效果实验,并在2015年1月-2015年6月对20名诊断为PLP的患者进行了实验。
  
所有的参与者使用视觉模拟评分量表(VAS)描述自己的疼痛感受,得分范围为0毫米(没有痛苦)到100毫米(巨大痛苦),并在使用计算机辅助冷冻消融术进行治疗,使用冷风技术(-40℃)封闭患肢局部神经通路7天和45天后再次进行疼痛评分。 

结果显示,在进行冷冻消融术之前,患者的疼痛评分平均为6.4分,手术45天后患者的平均疼痛分数降至2.4分。
  
Prologo表示,他们正努力说明AMA批准PLP治疗方案,但是他指出他们仍需进行更进一步的研究。
