: To evaluate the effects of tramadol hydrochloride associated to remote ischemic perconditioning on oxidative stress.
: Twenty five male rats (Wistar) underwent right nephrectomy and were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minutes of renal ischemia; Remote ischemic perconditioning group (Per) with three cycles of 10 minutes of I/R performed during kidney ischemia; Tramadol group (T) treated with tramadol hydrochloride (40mg/kg); remote ischemic perconditioning + Tramadol group (Per+T) with both treatments. Oxidative stress was assessed after 24 hours of reperfusion.
: Statistical differences were observed in MDA levels between I/R group with all groups (p<0.01), in addition there was difference between Tramadol with Sham, Per and Per+T groups (p<0.05), both in plasma and renal tissue.
: Remote ischemic perconditioning was more effective reducing renal ischemia-reperfusion injury than administration of tramadol or association of both treatments.
评估盐酸曲马多联合远程缺血预处理对氧化应激的影响。
25只雄性Wistar大鼠接受右肾切除术，并分为五组：假手术组（S）；缺血/再灌注组（I/R），肾缺血30分钟；远程缺血预处理组（Per），在肾脏缺血期间进行三个周期的10分钟缺血/再灌注；曲马多组（T），用盐酸曲马多（40mg/kg）治疗；远程缺血预处理+曲马多组（Per+T），接受两种治疗。再灌注24小时后评估氧化应激。
I/R组与所有组之间的丙二醛（MDA）水平存在统计学差异（p<0.01），此外，曲马多组与假手术组、Per组和Per+T组之间在血浆和肾组织中均存在差异（p<0.05）。
远程缺血预处理在减轻肾缺血-再灌注损伤方面比曲马多给药或两种治疗联合更有效。
