摘  要:目的探讨右美托咪啶复合舒芬太尼清醒镇静术用于老龄患者多发肠息肉切除术的有效性和可行性。方法选择2016年1至5月于北京大学第三医院接受多发肠息肉切除术的60例老龄患者,男28例,女32例;年龄65-80岁,平均年龄(70.4±4.5)岁;随机数字表法分为右美托咪啶组(D组)及丙泊酚组(P组),各30例。D组术前泵注右美托咪啶0.3 μg/kg, 10 min后静注舒芬太尼0.1 μg/kg,术中泵注右美托咪啶0.2-0.4 μg·kg^-1·min^-1;P组静注舒芬太尼0.1 μg/kg、丙泊酚1.5 mg/kg,术中泵注丙泊酚3-6 mg·kg^-1·h^-1。记录基础值、手术开始时、手术开始10 min、开始20 min、开始30 min、术毕及离室时的心率、平均动脉压、脉搏血氧饱和度、呼吸频率、脑电双频指数(BIS)值,同时记录镇静/警觉(OAA/S)评分及镇静后的其他临床效应。结果与基础值相比,给药后两组患者处于不同程度的镇静状态。D组患者手术开始时、手术开始10 min、开始20 min、开始30 min及术毕时的BIS值分别为89.6(87.8-91.0)、79.4(78.0-80.0)、76.9(75.0-80.0)、76.0(73.0-79.0)、75.6(70.0-79.0),显著低于基础值96.4(95.0-98.0),差异均有统计学意义(Z=-4.645, -4.788, -4.787, -4.789, -4.789,均P〈0.05);OAA/S评分分别为4.5(4.0-5.0)、3.4(3.0-4.0)、3.0(3.0-3.0)、3.5(3.0-4.0)、3.3(3.0-4.0)分,显著低于基础值4.8(5.0-5.0)分,差异有统计学意义(Z=-2.828,-4.862, -5.031, -4.420, -4.710,均P〈0.05)。P组患者手术开始时、手术开始10 min、开始20 min、开始30 min及术毕时的BIS值分别为54.7(50.0-59.3)、54.8(50.0-59.3)、50.7(47.8-56.8)、54.4(51.5-58.0)、53.7(50.0-57.3),显著低于基础值95.8(95.0-96.0),差异有统计学意义(Z=-4.786,-4.787, -4.788, -4.786, -4.786,均P〈0.05);OAA/S评分分别为0.4(0.0-1.0)、0.4(0.0-1.0)、0.4(0.0-1.0)、0.4(0.0-1.0)、0.4�ObjectiveTo explore the effectiveness and feasibility of conscious sedation with a low dose of dexmedetomidine and sufentanil during multiple intestinal polyps resection in elderly patients.MethodsSixty elderly patients who underwent multiple intestinal polyps resection in Peking University Third Hospital from Janurary to May 2016 were randomly divided into dexmedetomidine group (D group, n=30) and propofol group (P group, n=30). There were 28 males and 32 females with a mean age of (70.4±4.5) years old (range: 65-80 years old). The patients in the dexmedetomidine group received a loading dose of 0.3 μg/kg followed by a continuous infusion of 0.2-0.4 μg·kg^-1·min^-1 of dexmedetomidine and sufentanil (0.1 μg/kg) respectively.The patients in the propofol group received sufentanil 0.1 μg/kg and propofol 1.5 mg/kg and followed by a continuous infusion of 3-6 mg·kg^-1·h^-1 of propofol.Blood pressure, heart rate, pulse oxygen saturation (SpO2), respiratory rate and bispectral index (BIS) were recorded at the basic status and at the beginning of operation, 10 min, 20 min, 30 min after operation, the end of operation and departure.The observer′s assessment of alertness/sedation (OAA/S) scores and the clinical responses were also recorded.A statistical analysis was performed.ResultsAll patients in the two groups were sedated compared with baseline.The BIS values of patients in group D at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation were 89.6(87.8-91.0), 79.4(78.0-80.0), 76.9(75.0-80.0), 76.0(73.0-79.0) and 75.6(70.0-79.0) respectively, and those values were all significantly lower than baseline value[96.4(95.0-98.0)], (Z=-4.645, -4.788, -4.787, -4.789, -4.789, P〈0.05). The OAA/S score at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation were 4.5(4.0-5.0), 3.4(3.0-4.0), 3.0(3.0-3.0), 3.5(3.0-4.0) and 3.3(3.0-4.0) respectively, and were signif
