摘　　要：目的:评估左布比卡因硬膜外复合全身麻醉对结肠手术的影响。方法:择期行结肠癌手术的60例患者随机、双盲分为4组,对照组(S组)、0.125%左布比卡因组(L1组)、0.25%左布比卡因组(L2组)及0.5%左布比卡因组(L3组),各15例。S组硬外注射首量生理盐水10 m L,随后5 m L/h泵注至术毕,L1、L2、L3组则选用左布比卡因。硬膜外穿刺后行麻醉诱导,记录入室5 min、插管1 min、切皮、探查、开刀1 h、术毕、拔管、离开复苏室八个时点的平均血压、心率,并测血糖、皮质醇,记录麻醉时间、复苏室时间,出血量、输液量、不良反应,异丙酚、瑞芬太尼、麻黄素、芬太尼总量。结果:S组复苏时间长于其他3组,L1组瑞芬太尼、芬太尼大于L2、L3组,L3组麻黄素大于其他3组;L1组血糖高于L2、L3组,皮质醇高于L3组,L3组低血压例数高于其他3组。结论:0.25%左布比卡因硬膜外输注可减少应激反应,节俭阿片药物,减少复苏时间,不增加麻黄素使用。Objective To evaluate the impact of epidural anesthesia with levobupivacaine combined with general anesthesia on colon surgery. Methods Sixty patients undergoing elective radical procedure for colon carcinoma were randomLy divided into four groups： saline group （group S）, 0.125% levobupivacaine group （group L1）, 0.25% levobupivacaine group （group L2）, and 0.5% levobupivacaine group （group L3）. Group S received normal saline of 10 mL epidurally and then infusion of 5 mL·h-1 until the procedure was finished; groups L1, L2, and L3 received levobupivacaine instead. Anesthetic induction was performed after epidural puncture. Mean blood pressure and heart rate were recorded at 8 time points including 5 min after entering into the operation room, 1 min after intubation, skin incision, abdominal exploration, 1 h after skin incision, completion of operation, extubation, and leaving PACU; meanwhile blood glucose and cortisol were detected, anesthesia time, time to PACU stay, bleeding, transfusion volume, adverse reaction, and doses of propofol, remifentanil, ephedrine, and fentanyl were noted. Results Time to PACU stay was longer in S group than in other 3 groups. Doses of remifentanil and fentanyl were larger in L1 group than in L2 group and L3 group. Ephedrine dose in L3 group was larger than in other 3 groups. Blood sugar in L1 group was higher than L2 group and L3 group. Cortisol in S group was higher than in other 3 group. Cortisol in L1 group was higher than in L3 group. The number of patients with hypotension was greater in L3 group than other 3 groups. Conclusions Continue epidural infusion of 0.25%levobupivacaine can reduce stress response and opioid uses, shorten PACU stay, whereas it does not increase use of ephedrine.
