目的:观察全凭静脉麻醉下右美托咪定(dexmedetomidine,DEX)对脊柱矫形术患者唤醒麻醉期间唤醒质量的影响。方法:选择ASAⅡ~Ⅲ级的脊柱矫形术患者40例,随机分为两组(n=20);D组:DEX负荷剂量1μg/kg 泵注30 min,以0.5μg/(kg? h)维持;N组:以相同剂量的生理盐水替代。唤醒期间DEX和生理盐水泵注剂量降为0.2μg/(kg? h),停用其他所有麻醉药物。记录唤醒期间呼吸恢复时间( T1)、苏醒时间( T2)、唤醒前15 min、唤醒即刻、唤醒结束和拔管时心率( HR)、平均动脉压( MAP)和BIS值、唤醒期间Ramsay镇静评分、VAS评分。结果:两组患者呼吸恢复时间、苏醒时间无统计学差异( P>0.05)。唤醒期Ramsay镇静评分满意度D组明显高于N组(P<0.05),VAS评分D组比N组低(P<0.05),唤醒时躁动发生率N组多于D组(P<0.05),唤醒质量D组明显高于N组(P<0.025)。结论:唤醒期间持续输注右美托咪定不影响患者的苏醒时间,并能改善脊柱矫形术患者的术中唤醒质量。
目的:觀察全憑靜脈痳醉下右美託咪定(dexmedetomidine,DEX)對脊柱矯形術患者喚醒痳醉期間喚醒質量的影響。方法:選擇ASAⅡ~Ⅲ級的脊柱矯形術患者40例,隨機分為兩組(n=20);D組:DEX負荷劑量1μg/kg 泵註30 min,以0.5μg/(kg? h)維持;N組:以相同劑量的生理鹽水替代。喚醒期間DEX和生理鹽水泵註劑量降為0.2μg/(kg? h),停用其他所有痳醉藥物。記錄喚醒期間呼吸恢複時間( T1)、囌醒時間( T2)、喚醒前15 min、喚醒即刻、喚醒結束和拔管時心率( HR)、平均動脈壓( MAP)和BIS值、喚醒期間Ramsay鎮靜評分、VAS評分。結果:兩組患者呼吸恢複時間、囌醒時間無統計學差異( P>0.05)。喚醒期Ramsay鎮靜評分滿意度D組明顯高于N組(P<0.05),VAS評分D組比N組低(P<0.05),喚醒時躁動髮生率N組多于D組(P<0.05),喚醒質量D組明顯高于N組(P<0.025)。結論:喚醒期間持續輸註右美託咪定不影響患者的囌醒時間,併能改善脊柱矯形術患者的術中喚醒質量。

Objective:To evaluate effects of dexmedetomidine(DEX) on the wake-up quality of patients during spinal orthopaedic surgery by total intrave-nous anesthesia.Methods:Forty patients ( ASAⅡ -Ⅲ) undergoing spinal orthopedic surgery were randomized into group D and group N ( n =20 for each).Group D received infusion of DEX by loading dose of 1 μg/kg for 30 min,and maintained at the rate of 0.5 μg /(kg? h),and group N were given the same dose of 0.9% saline instead.During the wake-up test,the dose of DEX and saline was reduced to 0.2 μg /(kg? h),when all anesthetics were withdrawn.Index were recorded regarding breathing recovery time (T1),awakening time(T2),heart rate(HR) 15 min before wake-up,the moment of wake-up,after wake-up and extubation,mean arterial pressure(MAP) and BIS score,scoring on the Ramsay Sedation Scale and VAS during wake-up test. Results:The two groups were not different concerning the breathing recovery time and awakening time(P>0.05).During the wake-up time,group D had a higher the satisfaction by Ramsay Sedation Scale(P<0.05),and lower VAS score than group N(P<0.05),whereas group N had higher rate of agita-tion(P<0.025),and patient in group D had better wake-up quality(P<0.025).Conclusion:Continuous infusion of dexmeditomidine doesn′t inhibit the awakening time,yet may improve the wake-up quality for patients during the spinal orthopedic surgery.
