               [摘   要] 目的:评价右美托咪定(dexmedetomidine,Dex)混合罗哌卡因用于程控硬膜外间歇脉冲式分娩镇痛的效果及对产时
                发热的影响。方法:选择单胎足月妊娠初产妇104例,随机数表法分为0.1%罗哌卡因混合0.5 μg/mL右美托咪定组(RD组,n=
                52)和0.1%罗哌卡因混合1 μg/mL芬太尼组(RF组,n=52)。两组患者均接受程控硬膜外间歇脉冲式分娩镇痛。记录分娩镇痛
                前(T0)、给予负荷量后 30 min(T1)、1 h(T2 )、2 h(T3 )、4 h(T4 )、6 h(T5 )、宫口开全时(T6 )、胎儿娩出后2 h(T7 )8个时点的疼痛视觉
                模拟评分(visual analogue scale,VAS)、鼓膜温度。记录爆发痛、不良反应和新生儿1 min、5 min Apgar评分。于T0和T7时点抽取
                患者非输液侧静脉血,检测白细胞计数和 C 反应蛋白水平。结果:RD 组镇痛起效时间短于 RF 组(5.9 min vs. 8.7 min);RD 组
                T2~T6时点的VAS评分分别低于RF组(P<0.05);RD组爆发痛的发生率低于RF组(4.1% vs. 20.0%)(P<0.05)。RD组患者的发
                热率低于RF组(8.2% vs. 38.0%)(P<0.05);T4~T7时点,RD组的鼓膜温度分别低于RF组(P<0.05)。与T0时比较,两组患者T7
                时的白细胞计数和C反应蛋白均明显升高(P<0.01),而组间比较,差异无统计学意义(P > 0.05)。RD组皮肤瘙痒的发生率低
                于RF组(P<0.05)。结论:右美托咪定可增强罗哌卡因硬膜外分娩镇痛的效果,降低硬膜外分娩镇痛相关产时发热的几率和
                程度,而对母婴无不良影响。

                American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 20~35 years,weighing 60~85 kg,scheduled for elective labor
                analgesia,were divided into 0.1% ropivacaine mixed with 0.5 μg/ml dexmedetomidine(group RD,n=52)and 0.1% ropivacaine mixed
                with 1 μg/mL fentanyl(group RF,n=52)by a random number table method. Both groups received programmed intermittent epidural
                bolus technique in labor analgesia. The visual analogue scale(VAS)score and the maternal temperature were measured before
                anesthesia(T0 ),at 30 min(T1 ),1 h(T2 ),2 h(T3 ),4 h(T4 ),6 h(T5 )post analgesia,10 cm cervical dilatation(T6 )and 2 h after delivery
               (T7 ). Recording the incidence of breakthrough pain and the adverse effects,the Apgar scores were evaluated at 1 min and 5 min after
                the delivery. Venous blood samples were collected in non⁃infusion sides at T 0 and T7 to detect the maternal white blood cell count and
                serum C⁃reactive protein. Results:Compared with group RF,the onset time of analgesia was significantly shortened,the VAS scores at
                T2~6 and the incidence of breakthrough pain(4.1% vs. 20.0%)were lower in group RD(P < 0.05). The incidence of intrapartum fever
                was lower in group RD(8.2% vs. 38.0%),and also the maternal temperature at T 4~7 than those in group RF. Compared with T 0,the
