【摘要】:目的评价不同间隔时间行程控硬膜外脉冲式注射(programmed intermittent epidural bolus,PIEB)或连续硬膜外输注(continuous infusion epiduaral,CEI)复合PCEA用于分娩镇痛的效果。方法选择有分娩镇痛要求的足月初产妇186例,ASAⅠ或Ⅱ级,采用数字表法随机分为三组,每组62例。三组均使用首次剂量(0.125%罗哌卡因+0.4μg/ml舒芬太尼)10 ml,镇痛泵均使用(0.08%罗哌卡因+0.4μg/ml舒芬太尼)100ml。PIEB1组(P1组):5ml/30min,首次剂量注入30min后开始脉冲给药;PIEB2组(P2组):10 ml/60 min,首次剂量注入60 min后开始脉冲给药;CEI组(C组):10ml/h,首次剂量注入后立即开始持续给予背景剂量。三组均设置PCA量5ml,锁定时间30min。记录镇痛期间宫缩疼痛VAS评分、运动阻滞程度Bromage评分、VAS评分3分的例数和(MBS)评分1分的例数;记录最高感觉阻滞平面、镇痛药物用药总量、催产素使用量、PCEA按压次数,第一次追加药物时间、产程时间、分娩方式和产间发热的例数;记录不良反应的发生情况。结果三组在分娩镇痛开始后VAS评分均明显低于镇痛前,P2组VAS3分的比率明显低于P1组和C组(P0.05)。镇痛期间,P1组最高感觉阻滞平面明显高于P2组和C组,P2组单侧阻滞发生率明显低于C组(P0.05)。P2组镇痛药物用药总量、PCEA按压次数明显少于,第一次追加药物时间明显长于P1组和C组(P0.05)。P1组与P2组器械助产与产间发热的例数明显少于C组(P0.05)。结论在分娩镇痛中给予首次剂量后,间隔60min行PIEB模式注射技术,是一种更有效的给药方法。
