摘 要 目的:探讨盐酸右美托咪定连续静脉泵入联合罗哌卡因治疗顽固性晚期癌痛的疗效。方法:将98例顽固性晚期癌痛患者按照数字随机法随机分为观察组和对照组各49例,观察组选用盐酸右美托咪定连续静脉泵入联合罗哌卡因镇痛,对照组选用单纯盐酸右美托咪定连续静脉泵入镇痛,采用视觉模拟评分法(VAS) 评估患者在给药后的镇痛效果及满意度,并观察不良反应发生情况。结果:用药后,观察组VAS评分明显低于对照组( P<0.05);观察组和对照组不良反应发生率分别为6.12%和8.16%(P>0.05);观察组患者满意度为91.84%,明显高于对照组的81.63% ( P<0.05)。结论:盐酸右美托咪定连续静脉泵入联合罗哌卡因对顽固性晚期癌痛患者的镇痛效果显著,患者满意度高,值得临床推广。

ABSTRACT Objective: To explore the effect of the continuous intravenous pumping of dexmedetomidine hydrochloride combined with ropivacaine for the treatment of intractable advanced cancer pain. Methods: Ninety-eight cases of patients with intractable advanced cancer were randomly divided into an observation group and a control group with 49 cases each. The continuous intravenous pumping of dexmedetomidine hydrochloride combined with ropivacaine was given for analgesia in the observation group while only the continuous intravenous pumping of dexmedetomidine hydrochloride in the control group. Analgesia effect and satisfaction were evaluated by using a visual analog scale (VAS) after administration and the incidence of adverse reactions was also observed. Results: The VAS scores were significantly lower in the observation group than in the control group after treatment (P<0.05). The incidence of adverse reactions was 6.12% in the observation group and 8.16% in the control group (P>0.05). The satisfaction of patients was 91.84% in the observation group, which was significantly higher than 81.63% in the control group (P<0.05). Conclusion: The combination therapy has a significant analgesic effect with higher patient satisfaction and worthy of clinical promotion.

癌性疼痛是疼痛部位需要修复或调节的信息传递到神经中枢后引起的感觉,也称为癌痛。对于晚期癌痛患者,疼痛往往成为其生命最后阶段最为痛苦的经历,临床上口服或静脉注射阿片类药物是缓解疼痛的主要方法,但因不良反应多,故有效的镇痛治疗已成为目前亟待解决的问题[1]。笔者对本院98例顽固性晚期癌痛患者的治疗疗效进行观察,旨在探索对顽固性晚期癌痛有效治疗的新方法,现报道如下。

资料与方法

一般资料

入选2011年4月-2013年4月在本院就诊的98例顽固性晚期癌痛患者,按照数字随机法随机分为观察组和对照组各49例。纳入标准:① 经病理或细胞学确诊为晚期恶性肿瘤,预计生存期半年以上;② 无放化疗指征;③按照WHO推荐的三阶梯止痛法治疗无效;④对右美托咪定和罗哌卡因不过敏。排除标准:①伴有其他心、肝、肾等重要脏器严重性疾病;② 有精神病病史;③中途中止或拒绝参与本次试验。观察组中男31例,女18例,年龄34~78岁,平均年龄(54. 27±9.25)岁,其中肺癌10例,肝癌6例,肠癌11例,胃癌9例,乳腺癌9例,其他4例,视觉模拟评分法(VAS)疼痛评分为(9.13±1.27)分;对照组中男30例,女19例,年龄36~77岁,平均年龄(54.31±9.19)岁,其中肺癌11例,肝癌8例,肠癌10例,胃癌10例,乳腺癌7例,其他3例,VAS疼痛评分为(9.14±1.22)分。两组患者在性别、年龄、癌症类型、疼痛程度上比较无显著差异(P>0.05),具有可比性。所有患者均同意接受试验,签署知情同意书。
