癌痛的评估与护理(汉译英)

1、最新 料推荐癌痛的评估与护理疼痛是癌症病人普遍存在的症状。尽管在止痛方面取得了巨大进展，但仍有三分之二的癌症病人到晚期都要忍受癌痛的折磨。 因此，需要护士具备处理癌痛的多方知识， 掌握正确评估方法和治疗技术及恰当的护理。现就其综述如下。1 癌性疼痛的护理评估1.1视觉模拟评分法(Viraal AualortScale，简称 VAS) ：该法比较灵敏，有可比性。具体做法是：在纸上面划一条10 cm 的横线，横线的一端为0，表示无痛；另一端为10，表示剧痛； 中间部分表示不同程度的疼痛。让病人根据自我感觉在横线上划一记号，表示疼痛的程度。轻度疼痛平均值为 2.57 1.04；中度疼痛平均值为 5.

2、18 1.41；重度疼痛平均值为 8.41 1.35。1.2评估表法：它是由美国的McmilLan 设计的疼痛估计表。即0 等于无痛， 1 等于有疼痛感，但不严重；2 等于轻微疼痛，病人不舒服；3 等于疼痛，病人痛苦；4 等于疼痛较剧烈，有恐惧感； 5 等于剧痛。通过问答形式由病人做出具体描述。内容包括：疼痛程度、部位、性质、发作情况及伴发症状等。据报道此表设计合理，实用性强。1.3口述评估法 (Verbal Report) ：Melzack 拟定了 1 份形容疼痛程度词汇，如轻度疼痛、重度疼痛、 阵痛、可怕的痛及无法忍受的疼痛等来帮助病人描述自己的疼痛， 使病人更好地把疼痛加以表达，按 0

3、10 分次序报告， 0 分表示无痛， 10 分表示剧痛。此法简单，但不易发觉细微变化。2 癌痛的止痛治疗2.1 药物治疗： 世界卫生组织 (WHO) 提出 2000 年消除癌症患者疼痛的奋斗目标。其提出的三级止痛方案是目前世界各地都在大力推行的癌前药物治疗准则。也称“按需给药”，即一级止痛：轻度疼痛使用非麻醉性镇痛药。如阿斯匹林、扑热息痛等。二级止痛：中度持续性疼痛或加重，使用弱麻醉剂。如强痛定、可待因、美散痛等。三级止痛：强烈持续性疼痛，使用强麻醉剂，直到疼痛消失。如吗啡、杜冷丁等。其主要给药途径有以下几种：2.1.1 消化道给药： 药物给药近来提倡口服为主，对慢性癌痛采用布罗芬与美散痛合用

4、取得了良好效果，用布罗芬600 mg 与美散痛2.5 5 mg 合用，效果优于单独应用美散痛，而不增加副作用。 且对骨转移癌痛也有较好的止痛效果。研究中未发现布罗芬对十二指肠粘膜有损伤， 认为布罗芬的安全性和较低的副作用是可取的。近年来开发的盐酸双氢吗啡控释片，克服了吗啡的某些副反应，又增加了镇痛效果。已成为需要麻醉止痛时的首选药物。不能口服者也可直肠给药。芬太尼、buprenophine 也可舌下给药。2.1.2 连续皮下或静脉给药：当大量口服止痛药不能控制疼痛时，或有严重的胃肠道反应如恶心、呕吐等副作用时，需采用连续皮下或静脉内输入麻醉剂：Sheider 评估了这种方法，肯定了其给药的安全

5、性和效能，现已普遍应用。2.1.3 皮肤给药： 近年来由于皮肤生理研究和制药技术的发展，皮肤与粘膜已经作为给药的新途径。有报道，一次芬太尼贴敷止痛可达72 h 。虽使用方便，但价格昂贵。另外，中药外治法能使药物经皮肤吸收，起效快、安全、方便、毒副作用小。用药10 min 即可见效，总有效率 79.2%。2.1.4 病人控制的止痛 (Patient Controleel Analgesir ，简称 PCA) ：PCA 方法 1984 年在美国被有效地应用。 其方法是患者拥有一个用计数电子仪控制的注药泵。它可提供麻醉剂的剂量、剂量增减范围和估计2 次剂量的间隔最短时间， 以及提供一个稳定的注药间隔

6、周期。能更好地取得疼痛控制效果，减少麻醉剂用量，减少副作用。但其缺点是必须有一定设备，且价格昂贵。并可引起药物外渗、静脉炎及感染等。目前已研制出新型控制止病人的痛药泵，分家庭用、护士用及防止用药过量的PCA 3 种类型。不仅可防止病人用药过量，还可通过1最新 料推荐电脑程序控制持续输液中的止痛药浓度，以维持稳定的止痛效果，防止病人出现剧痛。2.1.5麻醉技术控制癌痛：神经阻滞在晚期癌痛病人中已应用了多年，近年来提倡在早期癌痛患者中应用。 通过导管或泵， 连续或间断将药物输入硬膜外或鞘内。 此法避免了口服给药和其他方法给药的副作用， 同时还减少了辅助药物的应用。 但也有人报道， 全身先用阿片类药

7、物治疗的病人，脊柱内再给阿片类药物则无治疗效果。2.1.6 神经外科技术控制癌痛： 手术治疗的目的是在周围神经与中枢神经之间某一点切断产生疼痛的途径。3 癌痛的护理3.1护理观念的更新：迅速有效地减轻癌痛是护理的基本要求，也是护士基本的责任。因此， 护士应尽力发展提高癌痛的护理水平。癌痛的控制往往受病人、 护士、药物组合多种因素的综合影响， 而护士的密切观察和及时提供适应的止痛方法是控制癌痛重要因素。这就需要护理教育计划从基础和临床上对药物的药理学和用药方式进一步加强，树立果断采取各种治疗手段， 设法解除病人痛苦， 提高病人生存质量延长生命的新观念，严格遵守有效控制疼痛的指导原则。3.2护士的

8、作用3.2.1准确评估： 在对癌痛控制过程中，疼痛的评估是第一重要环节。护士不仅要客观地判断疼痛是否存在， 还要确定疼痛的程度。在用药前护士必须根据个体疼痛作出准确的判断，采取相应措施，才能有效地减轻病人的痛苦。通过对1 400 名注册护士问卷调查表明，最佳处理疼痛的主要障碍是对疼痛估计不足，处理疼痛的知识不够及病人不愿报告疼痛。因此，对护士而言更重要的是有关疼痛的处理和用以解除癌痛的标准教育。3.2.2 准确及时给药： 观察效果及副作用。 包括了解治疗的基本原则，向病人说明接受治疗的效果及帮助病人正确用药，评估治疗效果，向医生报告以及副作用的防治等。3.2.3心理护理：要帮助病人树立信心。因

9、势利导，调动病人积极的心理因素，帮助克服其消极的心理因素。争取病人信任，增强病人的安全感，稳定情绪，解除焦虑。注意分散病人注意力。建立“舒适家庭病房” ，因为舒适可使心理生理异常减轻到最低程度。Assessment and care of cancer painPain is common symptom of cancer patients.
