本研究所采用的镇痛方法,术前口服塞来西布胶囊,降低疼痛超敏反应,术中注射长效止痛药物,术后继续规律口服塞来西布胶囊,并应用阿片类药物,是一种围术期的镇痛方法。塞来西布胶囊是特异性COX-2抑制剂,通过减少COX-2以抑制痛觉超敏,达到镇痛效果,且无传统非甾体类抗炎药的不良反应。术前应用塞来西布胶囊可以减少伤害性刺激传入所致的外周和中枢超敏,可起到超前镇痛的作用。罗哌卡因是一种长效酰胺类局麻药,其起效时间为2~5 min,持续时间可达6 h[11],是布比卡因的左旋异构体,中枢神经系统及心血管系统毒性均明显低于布比卡因,且不会引起致命的心律失常[12]。另外,罗哌卡因具有感觉与运动神经阻滞明显分离的特性,可在镇痛的同时增强肠蠕动,有利于术后肠功能的恢复[13]。研究表明,应激状态与创伤反应可彻底激活外周的阿片受体,使受体数量与阿片肽亲和力均显著增加,因此,手术时于外周组织注射吗啡可产生一定的镇痛效果[14]。本研究中,研究组在72 h内的镇痛效果非常明显,研究组哌替啶用量显著少于对照组,且研究组初次母乳哺乳时间与肛门排气时间明显早于对照组。产科提倡早期母乳喂养,本研究中研究组产妇泌乳时间明显早于对照组,且24 h泌乳次数明显多于对照组。
良好的镇痛效果、较少的不良反应与低廉的住院费用一直是临床医师所关心的问题,本研究所采用的联合镇痛措施,其镇痛效果明显,应用方便,不良反应少,相信会作为一种有效的超前镇痛措施在临床上得到应用。
