说痛的

《媚行者》实在太好看,每看两行就想做个笔记

幻痛可以在手术以后,即时出现,也可以在手术完成以后多时才出现。另一个调查报告显示,如果将痛楚程度分零至九度,零度微痛,九度极痛,有百分之八十三有幻痛的被访者,痛度位于三至六度之间,微痛与极痛的被访者比率相若,极痛者占百分之九,微痛者占百分之八。痛楚有刺痛(37)、痒痛(28)、抽痛(28)、烧痛(26)、撕痛(25)、抽搐痛(25)、诱痛(25)、极瘘(21)、切痛(18)、闷痛(14)、其他(l0)、热痛(o)、击痛(3)、扯痛(2),括弧内是受访者痛楚出现的次数。打呵欠,大便或咳嗽都可以引起严重的幻痛。

幻肢通常呈现伤者肢体受伤时的形态,譬如潜水时受伤,伤者就会感觉幻肢在水中浮动,如果开车时受伤,伤者会感觉断肢还在踏油门,如果滑雪,断肢就会感觉微曲微侧。痛的位置也会受受伤肢体前病影响,如伤者受伤前曾膝痛,即使膝盖切除后,仍会感到膝痛。

治疗方法包括局部电疗止痛,于诱发痛楚点注射止痛药,切除痛楚神经,心理治疗,但没有一种治疗方法可以完全止痛,亦无法治好痛楚。减轻痛楚的方法有按摩断肢,热敷,微波或超声波止痛。
