摘要:

目的: 探讨右美托咪定在老年患者内镜黏膜下剥离术(endoscopic submucosal dissection,ESD)手术中的应用。方法: 将60例在本院进行ESD手术的老年患者分为研究组和对照组,每组30例。研究组术前给予泵注0.5 μg/kg的右美托咪定。对照组给予等量的生理盐水。术中,两组均持续输注丙泊酚。对比两组手术时间、麻醉时间、苏醒时间、丙泊酚用量。分别于术前、术后6 h、术后1 d、术后3 d,采用简易智力状态检查表(MMSE)评估患者认知功能变化,同时评估术后认知功能障碍(POCD)的发生情况。结果: 两组手术时间、麻醉时间对比,差异无统计学意义(P>0.05);研究组的苏醒时间、丙泊酚用量显著低于对照组,差异有统计学意义(P<0.05);术后6 h、术后1 d、术后3 d,观察组MMSE评分的显著高于对照组,差异有统计学意义(P<0.05);术后6 h、术后1 d、术后3 d,研究组的POCD发生情况显著轻于对照组,差异有统计学意义(P<0.05);研究组不良反应发生率(6.67%)显著低于对照组(30.00%),差异有统计学意义(P<0.05)。结论: 右美托咪定对老年患者ESD手术后的认知功能具有保护作用。

Abstract:

AIM: To investigate the effects of dexmedetomidine in elderly patients with endoscopic submucosal dissection (endoscopic submucosal dissection, ESD) used in operation.  METHODS:Sixty elderly patients who underwent ESD operation in our hospital were divided into study group and control group, each group included 30 cases. The study group was given 0.5 μg/kg infusion of dexmedetomidine. The control group was given the same amount of saline. During operation, two groups weregiven continuous infusion of propofol. The operation time, anesthesia time, recovery time, propofol dosage were compared between the two groups. Post-operative cognitive function(POCD) was assessed by mini mental state examination (MMSE) before and 6 hours after operation, on the postoperative day 1 and day 3 after operation, and the incidence of POCD was assessed. RESULTS:Comparison of operation time, anesthesia time in two groups. The difference was not statistically significant (P>0.05). The recovery time and propofol dosage in the study group were significantly lower than those in the control group. The difference was statistically significant (P<0.05). Postoperative 6 hours, postoperative day 1, postoperative day 3, the observation group MMSE score was significantly higher than that of the control group. The difference was statistically significant (P<0.05). Postoperative 6 hours, postoperative day 1, postoperative day 3, the study group POCD was significantly lighter than that of the control group. The difference was statistically significant (P<0.05). The incidence of adverse reactions in the study group (6.67%) was significantly lower than that in the control group (30%). The difference was statistically significant (P<0.05). CONCLUSION: Dexmedetomidine has a protective effect on cognitive function in elderly patients after ESD surgery.
