【摘要】 目的:分析右美托咪定門静脉预处理对肝部分切除术患者肝脏缺血-再灌注损伤中炎症反应及氧化应激的价值。方法:选择2016年2月-2020年1月全身麻醉下肝部分切除术105例患者,以随机数字表法分为A、B、C组,每组35例。A组在门静脉游离后经门静脉输注1.0 μg/kg右美托咪定,B组在门静脉游离后经颈内静脉输注1.0 μg/kg右美托咪定,C组在门静脉游离后经颈内静脉输注等量0.9%氯化钠注射液。三组于肝门阻断前10 min(T0)以及肝门开放后1 h(T1)、6 h(T2)、12 h(T3)采集颈内静脉血,检测指标包括肿瘤坏死因子-α(TNF-α)、白细胞介素-33(IL-33)、高迁移率族蛋白1(HMGB1)、血红素氧合酶-1(HO-1)、超氧化物歧化酶(SOD)。结果:与T0比较,各组T1、T2、T3的TNF-α、IL-33、HMGB1、HO-1均明显升高,SOD活性均明显降低(P<0.05)。与C组比较,A、B组T1、T2、T3的TNF-α、IL-33、HMGB1均明显下降,而HO-1、SOD均明显升高(P<0.05);与B组比较,A组上述各时间点的TNF-α、IL-33、HMGB1均明显下降,而HO-1、SOD均明显升高(P<0.05)。结论:右美托咪定门静脉预处理能显著减轻肝部分切除术患者肝缺血-再灌注损伤,使炎症反应与氧化应激得到有效抑制,并增强抗炎抗氧化能力。

[Abstract] Objective: To analyze the value of Dexmedetomidine via portal vein preconditioning on inflammatory response and oxidative stress in hepatic ischemia-reperfusion injury in patients with partial hepatectomy. Method: A total of 105 patients with partial hepatectomy under general anesthesia from February 2016 to January 2020 were selected and randomly divided into group A, group B and group C, 35 cases in each group. Group A received 1.0 μg/kg Dexmedetomidine via portal vein after portal vein dissociation, group B received 1.0 μg/kg Dexmedetomidine via internal jugular vein after portal vein dissection, and group C received intrajugular Dexmedetomidine after portal vein dissociation intravenous infusion of 0.9% Sodium Chloride Injection. The internal jugular vein blood samples were collected at 10 min (T0) before hepatic portal occlusion and at 1 h (T1), 6 h (T2), 12 h (T3) after hepatic portal opening. The detection indexes included tumor necrosis factor-α (TNF-α), interleukin-33 (IL-33), high mobility group protein 1 (HMGB1), heme oxygenase-1 (HO-1) and superoxide dismutase (SOD). Result: Compared with T0, TNF-α, IL-33, HMGB1, HO-1 at T1, T2, T3 in each group were significantly increased, and SOD activity were significantly decreased (P<0.05). Compared with group C, TNF-α, IL-33 and HMGB1 in group A and group B were significantly decreased at T1, T2, T3, while HO-1 and SOD were significantly increased (P<0.05). Compared with group B, TNF-α, IL-33, HMGB1 in group A were significantly decreased, while HO-1 and SOD were significantly increased (P<0.05). Conclusion: Dexmedetomidine via portal vein preconditioning in patients with partial hepatectomy can significantly reduce hepatic ischemia-reperfusion injury, effectively inhibit inflammatory reaction and oxidative stress, and enhance anti-inflammatory and antioxidant capacity.

目前肝脏缺血-再灌注损伤(hepatic ischemia-reperfusion injury,HIRI)已成为肝部分切除术后患者肝功能异常甚至肝衰竭的重要原因[1]。右美托咪定是一类高选择性α2肾上腺素能受体激动药,不仅能用于镇静、抑制交感神经活性,还具有潜在保护神经作用[2]。文献[3]报道经中心静脉或外周静脉输注右美托咪定后,可經不同途径抑制中性粒细胞浸润及肝巨噬细胞活化,使得细胞因子释放减少以发挥减轻HIRI的作用。本研究拟分析右美托咪定门静脉预处理对肝部分切除术患者HIRI中炎症反应与氧化应激的价值,现报道如下。
