摘  要:目的:探讨3个不同时点泵注右美托咪定对全凭七氟醚麻醉腹腔镜胆囊切除术老年患者围拔管期应激与认知功能的影响。方法选择择期腹腔镜胆囊切除术老年患者100例,随机分为4组:对照组(C 组)、麻醉前20 min 泵注右美托咪定组(D1组)、插管后泵注右美托咪定组(D2组)、拔管前20 min 泵注右美托咪啶组(D3组),每组25例。对照组于麻醉诱导前20 min 泵入同等容量的生理盐水,D1、D2、D3组均泵注0.4μg/kg(根据药物使用说明书及临床应用指导意见,10 min 泵入)右美托咪定。于使用药物前(T1)、自主呼吸恢复时(T2)、拔管即刻(T3)、拔管后5 min(T4)、拔管后15 min(T5)记录患者的 HR 、MAP 和 Riker 镇静和躁动评分(SAS);用蒙特利尔认知评估量表(MoCA)对患者术前1 d 、术后1、3 d 认知功能进行评定并比较术后认知功能障碍发生率。结果4组患者年龄、BIM 、麻醉时间、受教育程度、术中输液量与出血量比较差异无统计学意义( P>0.05);与 D1组比较,D2组各时点 HR 、MAP 、Riker 镇静和躁动评分(SAS)差异无统计学意义(P >0.05),D1与 D2组 T3~ T5时点 HR 、MAP 、Riker 镇静和躁动评分(SAS)有所升高但差异无统计学意义(P>0.05);D3组 T2~ T5各时点 HR 、MAP 无明显升高,Riker 镇静和躁动评分(SAS)较低;对照组 T2~ T4时点 HR 、MAP 和 Riker 镇静和躁动评分(SAS)明显升高,且差异有显著性统计学意义( P <0.01)。4组患者术前1 d 认知功能比较差异无统计学意义(P >0.05);4组患者在术后1 d 认知功能有所下降,术后与术前比较,差异有统计学意义(P <0.05);D1、D2、D3组患者术后1天认知功能障碍发生率低于对照组(P <0.05);术后3 d 对照组患者仍有32%存在 POCD ,还有2例处于中度认知障碍,D1组患者仅有8%存在 POCD ,D2组�Objective To explpore the influence of three different time points(2 0 minutes before anesthesi-a 、after nasotracheal intubation 、2 0 minutes before extubation) for dexmedetomidine on extubation stress and cognitive function after the laparoscopic cholecystectomy in the elderly patients undergoing sevoflurane anesthesi-a .Methods One - hundred cases of elderly patients undergoing elective laparoscopic cholecystectomy were ran-domly divided into four groups( n = 2 5 ) :group D1 、D2 、D3 and C .All of the patients of group D1 、D2 、D3 re-ceived injection pump dexmedetomidine 0 .4 μg .kg - 1 (Guidance on the use of drug use and clinical application) respectively 2 0 minutes before anesthesia 、after nasotracheal intubation 、2 0 minutes before extubation within 1 0 minutes .The patients of group C only received an injection pump of same amount of saline .Mean blood pressure (MAP) ,heart rate(HR) ,Riker sedation and agitation assessment(SAS) were evaluated at time points of before using drugs(T1 ) 、spontaneous breathing recovery (T2 ) 、extubating (T3 ) 、5 minutes after extubation (T4 ) 、1 5 minutes after extubation(T5 ) .The cognitive function of preoperative 1 d 、postoperative 1 、3 d were evaluated by Montreal cognitive assessment scale (MoCA) ,and to compare with the incidence rate of postoperative cognitive dysfunction ,The concentration of serum insulin growth factor - 1 was detected at time points of preoperative 1 d 、postoperative 1 、3 d .Results There was no significant difference between the four groups in age ,BIM , anesthesia time ,education level ,intraoperative transfusion volume and blood loss( P 〉 0 .0 5 ) ;Compared with the D1 group ,there was no significant difference in HR ,MAP ,Riker sedation and agitation score(SAS) in D2 group( P 〉 0 .0 5 ) ,The HR ,MAP ,Riker sedation and agitation score(SAS)of D1 and D2 group were increased at the time point of T3 ~ T5 but there was no significant difference(P
