【摘要】:目的:评价右美托咪定对肢体缺血再灌注诱发肺损伤的影响。方法:择期行择期行下肢手术患者40例,性别不限,年龄40~65岁,体质量50~85 kg,ASA分级Ⅰ或Ⅱ级。采用随机数字表法,将其分为2组(n=20):对照组(C组)和右美托咪定组(D组)。麻醉诱导后气管插管,机械通气,采用静吸复合麻醉。麻醉诱导后,D组静脉输注右美托咪定1μg·kg-1(加入100 ml生理盐水),C组给予生理盐水,于止血带充气前滴注完毕。于麻醉诱导前(T1)、止血带充气(T2)、60 min(T3)、90 min(T4)时,止血带放气后5 min(T5)、30 min(T6)时采集桡动脉血样,行血气分析,计算氧合指数和呼吸指数。测定血浆白介素6(IL-6)、丙二醛(MDA)及细胞间黏附分子(ICAM-1)的浓度。结果:与C组相比,D组T2~5时RI升高(P0.05),而OI差异无统计学意义(P0.05);D组T2~6时血浆IL-6、MDA及ICAM-1的浓度降低(P0.05)。结论:右美托咪定可减轻肢体缺血再灌注诱发的肺损伤,其机制与抑制炎性反应有关。
