目的观察对比肝癌射频消融术患者应用右美托咪啶和瑞芬太尼清醒镇静的临床效果。方法选择国家癌症中心/中国医学科学院北京协和医学院肿瘤医院2014年1月至2016年6月择期行肝癌射频消融手术、美国麻醉医师协会(ASA)Ⅰ~Ⅱ级、年龄41~73岁患者60例,采用随机数字表法将其分为:右美托咪啶组(D组)和瑞芬太尼组(R组),每组30例患者。D组患者10 min内静脉输注负荷右美托咪啶0.5 μg/kg,随后以0.2~1.0 μg·kg-1·h-1的速度持续输注,直至Ramsay镇静评分达到3~4分;R组患者静脉输注负荷剂量瑞芬太尼1 μg/kg,随后持续静脉输注瑞芬太尼4~10 μg·kg-1·h-1和丙泊酚1~2 mg·kg-1·h-1,直至Ramsay镇静评分达到3~4分。记录患者进入手术室(T0)、穿刺时(T1)、射频消融开始后15 min(T2)、射频消融结束退针时(T3)以及术后30 min时(T4)的血液动力学指标、呼吸频率、脉搏血氧饱和度(SpO2)和镇痛数字评分(NRS)。评估麻醉效果,记录术中呼吸抑制、术后恶心呕吐发生情况,统计患者和手术医生满意度。结果R组患者T2时刻的血压和心率分别为(92.2±15.7)mmHg和(69.7±15.3)次/min,低于D组的(102.4±16.7)mmHg和(79.4±17.7)次/min,差异有统计学意义(t=-2.437、-2.271,均P〈0.05)。R组患者在T1、T2和T3时的呼吸频率分别为(10.1±1.9)、(10.8±1.5)和(13.4±1.6)次/min,低于D组的(12.3±1.7)、(13.6±1.6)和(14.5±1.4)次/min,差异均有统计学意义(t=-4.726、-6.993、-2.834,均P〈0.05)。术中R组舒芬太尼用量为(23.2±8.3)μg,明显少于D组的(35.5±11.7)μg,R组T2和T3时NRS分别为(2.4±1.1)和(2.4±1.3)分,低于D组的(3.5±1.2)和(3.6±1.1)分,R组T4时NRS为(3.4±1.1)分,高于D组的(2.1±0.9)分,差异均有统计学意义(t=-4.696、-3.701、-3.860、
ObjectiveThis study aimed to compare dexmedetomidine with remifentanil for conscious sedation in patients undergoing radiofrequency ablation of hepatocellular carcinoma.MethodsSixty patients, who were aged 41 to 73 years with American Society of Anesthesiologists (ASA) physical status Ⅰ-Ⅱ, and scheduled for elective radiofrequency ablation of hepatocellular carcinoma under conscious sedation in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, from January 2014 to June 2016, were allocated randomly to receive dexmedetomidine maintenance regimen(group D, n=30)or remifentanil maintenance regimen(group R, n=30)by random digital table. Subjects in group D received dexmedetomidine at a loading dose of 0.5 μg/kg over 10 min followed by 0.2-1.0 μg·kg-1·h-1 infusion until Ramsay sedation scale reached 3-4. Patients in group R received a loading dose of remifentanil 1 μg/kg followed by remifentanil 4-10 μg·kg-1·h-1 infusion and propofol 1-2 mg·kg-1·h-1 infusion until Ramsay sedation scale reached 3-4. Haemodynamic variables, respiratory rate(RR), pulse oxygen saturation (SpO2)and numeric rating scales(NRS) in each group were collected at entrance(T0), puncturing(T1), 15 min after beginning of radiofrequency ablation(T2), the end of radiofrequency ablation(T3) and 30 min after operation(T4). Efficacy of anesthesia, incidences of intraoperative respiratory depression, postoperative nausea and vomiting, patient and surgeon satisfaction were evaluated.
ResultsCompared with group D, the arterial blood pressure and heart rate at T2 [(92.2±15.7)mmHg vs (102.4±16.7)mmHg, (69.7±15.3) beats/min vs (79.4±17.7) beats/min] and respiratory rate at T1, T2 and T3 [(10.1±1.9) breaths/min vs(12.3±1.7) breaths/min, (10.8±1.5) breaths/min vs(13.6±1.6) breaths/min, (13.4±1.6) breaths/min vs(14.5±1.4)breaths/min] were significantly lower in group R (t=-2.437, -2.271, -4.726,
