摘要:

目的分析不同剂量右美托咪定对老年胃癌根治术患者氧化应激反应、认知功能的影响。方法收集2021年2月—2023年1月在西安大兴医院行胃癌根治术的老年胃癌患者88例,随机分为低剂量组[0.5 µg/(kg·h)速率泵注右美托咪定]、高剂量组[1 μg/(kg·h)速率泵注右美托咪定],记录围术期指标及患者麻醉前(T0)、麻醉后5 min(T1)、切皮时(T2)、手术结束时(T3)心率(heart rate, HR)、平均动脉压(mean arterial pressure, MAP),测量术前及术后1天患者血清丙二醛(malondialdehyde, MDA)、超氧化物歧化酶(superoxide dismutase, SOD)水平,利用蒙特利尔认知评估量表(Montreal cognitive assessment, MoCA)及简明精神状态检查表(mini‐mental state examination, MMSE)评估患者术前及术后1天认知功能,统计患者认知功能障碍发生情况。结果高剂量组与低剂量组手术用时、麻醉时长、失血量比较,差异均无统计学意义(P> 0.05);T2、T3时高剂量组HR、MAP均低于低剂量组,差异有统计学意义(P< 0.05);术后1天高剂量组血清MDA低于低剂量组,SOD水平高于低剂量组,差异有统计学意义(P< 0.05);术后1天高剂量组MoCA、MMSE评分高于低剂量组,差异有统计学意义(P< 0.05);术后1天高剂量组认知功能障碍发生率低于低剂量组,差异有统计学意义(P< 0.05)。结论老年胃癌根治术患者接受1 µg/(kg·h)右美托咪定可有效减轻其氧化应激反应,保护患者认知功能,降低认知功能障碍发生风险。

Abstract:

ObjectiveTo analyze the effects of different doses of dexmedetomidine on oxidative stress response and cognitive function in elderly patients undergoing radical gastrectomy.MethodsA total of 88 elderly patients with gastric cancer who underwent radical gastrectomy in our hospital from February 2021 to January 2023 were randomly divided into low-dose group [0.5 µg/(kg·h) pumping dexmedetomidine] andthe high-dose group [dexmedetomidine pumped at a rate of 1 µg/(kg·h)]. The perioperative indicators, the patient’s pre-anesthesia (T0), 5 min after anesthesia (T1), skin incision (T2), the end of the operation (T3) , heart rate (HR), mean arterial pressure (MAP), serum malondialdehyde (MDA) and superoxide dismutase (SOD) were measured before operation and 1 day after operation. The Montreal cognitive assessment (MoCA) and the mini-mental state examination (MMSE) were used to evaluate the cognitive function of the patients before operation and 1 day after the operation, and the occurrence of cognitive dysfunction in the patients was counted.ResultsThere was no significant difference in operation duration, anesthesia duration, and blood loss between the high-dose group and the low-dose group (P> 0.05); HR and MAP in the high-dose group were lower than those in the low-dose group at T2 and T3 (P< 0.05); the serum MDA level of the high-dose group was significantly lower than that of the low-dose group 1 day after operation, and the SOD level was higher than that of the low-dose group (P< 0.05); the MoCA and MMSE scores of the high-dose group were significantly higher than those of the low-dose group 1 day after operation (P< 0.05); the incidence of cognitive dysfunction in the high-dose group was significantly lower than that in the low-dose group 1 day after operation (P< 0.05).Conclusion1 µg/(kg·h) dexmedetomidine can effectively reduce the oxidative stress response of elderly patients undergoing radical gastrectomy, protect the cognitive function of patients and reduce the risk of cognitive dysfunction.
