Abstract

Cardiopulmonary bypass (CPB) surgery with extracorporeal circulation produce changes in the immune system and plasma levels of inflammatory cytokines. we hypothesize that Dexmedetomidine as an adjuvant , modulates the inflammatory response after CABG. In a prospective, randomized, blind study, 31 patients were assigned to Dexmedetomidine (Dex) group and compared with control group of 30 patients. Dex was administered at a loading dose of 0.5 μg/kg for 10 min , followed by a continuous infusion of 0.5 μg/kg per hour until the completion of CABG with CPB . The endpoints used to assess inflammatory responses to mini - CPB were plasma tumor necrosis factor (TNF) - � , interleukin (IL - 6 ) and interleukin ( IL - 10) levels. The inflammatory markers (IL - 6 , IL - 10 , TNF - � ) were determined after Dex administration , before CPB and 24 hours after admission to ICU. Biochemical factors including glucose , creatinine , lactate , BUN, AST , ALT , LDH were determined before CPB, immediately after entering the ICU , 24 hr , 48 hr and 72 hr post admission to ICU. Hemodynamic variables were also determined. Dex group was associated with a significant reduction in urea and creatinine. There were no significant differences in glucose, lactate, liver enzymes, LDH , IL - 6, IL - 10 and hemodynamic variables. In contrast, the surgery - induced increase in TNF - � levels in the Dex group was significantly higher compared with the control group.
