摘要 目的比较自动定量输注(ARB)与持续恒速输注(CI)技术在全膝关节置换术(TKA)术后持续股神经阻滞(CFNB)中的镇痛效果。方法选择行单侧TKA手术的患者120例,随机分为ARB组和CI组,每组60例。两组均连接电子自控输注泵术后镇痛,负荷剂量为0.33%罗哌卡因10 mL,持续镇痛配方为0.2%罗哌卡因(600 mg罗哌卡因用生理盐水配制成300 mL)。ARB组每隔1 h泵注5 mL,CI组持续恒速泵注5 mL/h,两组均复合PCA(5 mL/次)技术,锁定时间15 min。两组均行腰硬联合麻醉,术毕行股神经旁穿刺置管,连接电子自控输注泵行术后镇痛。记录两组患者术后不同时间点静息和活动时的疼痛评分、术后镇痛药物使用量、术后膝关节活动度及股四头肌肌力、不良反应的发生情况等。结果 ARB组患者术后8、12、24、36、72 h静息时疼痛评分及术后12、24、36、72 h活动时疼痛评分低于CI组(P<0.05),镇痛药物使用量减少;术后1、2、3 d的膝关节活动度ARB组优于CI组(P<0.05),股四头肌肌力分级两组差异无统计学意义(P>0.05)。结论在TKA术后CFNB镇痛中,ABR比传统的CI技术镇痛效果好,术后镇痛药物的使用量减少,同时不增加对运动神经的阻滞作用,为TKA术后股神经置管镇痛较理想的给药方式。
