摘　　要：目的探讨不同剂量右美托咪啶对甲状腺癌患者术后苏醒质量的影响。方法选择甲状腺癌手术患者140例。按照随机数字法分为A组46例,B组47例,对照组47例。3组患者麻醉诱导及维持方法相同。A组、B组患者于诱导后30 min内分别静脉泵入右美托咪啶0.4μg/kg和0.8μg/kg,对照组患者泵入等量生理盐水。记录右美托咪啶给药前(T0)、手术结束时(T1)、睁眼即刻(T2)、拔管即刻(T3)、拔管后10 min(T4)的心率(HR)、收缩压(SBP)和舒张压(DBP),手术开始前和结束时的PETCO2,手术结束至患者睁眼、拔管所用时间,评定苏醒躁动程度评分(RS)、镇静评分(Ramsay)和拔管后10 min疼痛视觉评分(VAS),观察拔管期间的不良反应。结果 T1、T2、T3和T4时,A组和B组患者HR显著低于对照组(P<0.05);T3、T4时,B组患者HR显著低于A组(P<0.05)。T1、T2、T3和T4时,A组患者SBP显著低于对照组(P<0.05);T2、T3和T4时,B组患者SBP显著低于对照组(P<0.05);T1、T2、T3时,B组SBP显著低于A组(P<0.05)。T3、T4时,A组患者DBP显著低于对照组(P<0.05);T2、T3和T4时,B组患者DBP显著低于对照组(P<0.05);T2时,B组DBP显著低于A组(P<0.05)。A组、B组患者RS评分和VAS评分显著低于对照组,B组VAS评分显著低于A组。A组患者Ramsay评分显著高于对照组(P<0.05),B组患者Ramsay评分、手术结束至患者睁眼和拔管时间显著高于对照组(P<0.05),B组患者手术结束至患者睁眼和拔管时间显著高于A组(P<0.05)。A组和B组苏醒期的不良反应发生率显著低于对照组(P<0.05)。结论 0.4μg/kg剂量的右美托咪啶为甲状腺癌手术全麻诱导后泵入的最佳剂量,能有效预防甲状腺癌患者手术全麻恢复期应激反应,维持心率、血压的平稳,且不影响苏醒时间和拔管时间,不良反应少,使甲状腺癌手术患者获得满意的苏醒质量。Objective To investigate the effect of different doses of dexmedetomidine on general anesthesia convales -cence of patients with thyroid carcinoma after surgery.Methods 140 cases of patients with thyroid cancer ,according to the ran-dom number method,were divided into group A of 46 cases,group B of 47 cases,47 cases was the control group.Anesthesia in-duction and maintenance methods were the same in the 3 groups.Patients of group A and group B were within 30 min after induc-tion respectively vein pump into dexmedetomidine 0.4 g/kg and 0.8 g/kg,and the control group ,the pump into the normal sa-line.Dexmedetomidine to medicine before（T0）,and at the end of surgery（T1）,eyes immediately（T2）,extubation（T3）,extuba-tion after 10 min（T4）,heart rate（HR）,systolic blood pressure（SBP）and diastolic blood pressure（DBP）were recorded,to start the operation before and at the end of P et CO2 end of surgery to the affected person eye opening ,extubation time.To assess the re-covery of agitation degree score（RS）,sedation score（Ramsay）and 10min pain visual score（VAS）,and adverse reactions during extubation.Results At T1,T2,T3 and T4,group A and group B of patients with HR were significantly lower than the control group（P〈0.05）and at T3,T4,group B with HR was significantly lower than group A （P〈0.05）.At T1,T2,T3 and T4,group A with SBP was significantly lower than the control group （ P〈0.05）;at T2,T3 and T4,group B with SBP was significantly lower than the control group（P〈0.05）;at T1,T2 and T3,SBP of group B was significantly lower than that of group A （P〈0.05）.At T3,T4,patients with DBP of group A was significantly lower than the control group （P〈0.05）;at T2,T3 and T4,patients with DBP of group B significantly lower than the control group （P〈0.05）;at T2 the DBP of group B was significantly lower than group A（P〈0.05）.RS score and VAS score of group A were significantly lower than those of the control group ,Ramsay score was sig nificantly highe
