| TITLE： | Effects of dexmedetomidine-assisted general anesthesia on the hemodynamics and cognitive function in elderly patients undergoing painless enteroscopy |
| 摘要： | 目的 探讨右美托咪定（DEX）辅助全身麻醉对老年无痛肠镜检查患者血流动力学及认知功能的影响。方法将2020年7月至2022年2月在焦作市第二人民医院门诊手术室行无痛肠镜检查的老年患者180例，根据随机数字表法分为对照组（n＝90）和观察组（n＝90）。对照组患者给予常规全身麻醉（舒芬太尼+丙泊酚麻醉诱导，丙泊酚麻醉维持）；观察组患者在术前准备后加用DEX辅助全身麻醉。比较2组患者的血流动力学指标[平均动脉压（MAP）、心率（HR）]、全麻用药量、苏醒时间、认知功能[简易精神状况检查量表（MMSE）]评分、不良反应发生率。结果2组患者麻醉前（T0）各项指标的差异均无统计学意义（P＞0.05）；与T0时比较，麻醉10min后（T1）、肠镜达回盲部（T2）、检查后退镜（T3）、术后10min（T4）时两组患者的MAP、HR均显著降低，但观察组患者在T1、T2、T3、T4时的MAP、HR均显著高于对照组（P＜0.05）。与对照组比较，观察组患者的全麻用药量显著降低，苏醒时间显著缩短，术后1、2、3d的MMSE评分显著升高，认知功能障碍发生率及不良反应发生率均显著降低（P＜0.05）。结论DEX可有效改善老年无痛肠镜检查患者的血流动力学及认知功能，减少全麻用药量，缩短患者苏醒时间，且安全性较好。 |
| ABSTRACT： | OBJECTIVE To investigate the effects of dexmedetomidine （DEX）-assisted general anesthesia on hemodynamics and cognitive function in elderly patients undergoing painless enteroscopy. METHODS From July 2020 to February 2022， 180 elderly patients undergoing painless enteroscopy in the outpatient operating room of the Second People’s Hospital of Jiaozuo were selected and divided into a control group （n＝90） and an observation group （n＝90） according to the random number table method. The control group was given routine general anesthesia （induced with sufentanil and propofol anesthesia， maintained with propofol anesthesia）， while the observation group was given DEX-assisted general anesthesia after preoperative preparation. The hemodynamic indexes [mean arterial pressure （MAP）， heart rate （HR）]， dosage of general anesthesia， awakening time， cognitive function [minimized mental status examination （MMSE）]， and the incidence of adverse drug reactions were compared between the two groups. RESULTS There was no significant difference in various indicators before anesthesia （T0） between 2 groups （P＞ 0.05）. Compared with T0， MAP and HR of the two groups were reduced significantly 10 minutes after anesthesia （T1）， at the time of enteroscope reaching the ileum and cecum （T2）， enteroscope withdrawal after the examination （T3）， and 10 minutes after surgery （T4）； but MAP and HR of the observation group at T1， T2， T3， and T4 were all higher than those of the control group （P＜0.05）. Compared with the control group， the dosage of general anesthesia and the recovery time in the observation group were significantly reduced or shortened， the MMSE scores at 1， 2 and 3 days after the operation were significantly increased， while the incidence of cognitive dysfunction and adverse reactions were significantly reduced （P＜0.05）. CONCLUSIONS DEX can effectively improve the hemodynamics and cognitive function of elderly patients undergoing painless enteroscopy， which is beneficial to reduce the dosage of general anesthesia， shorten recovery time， and has better safety. |
