We sought to investigate the effects of the TCI method on blood urea nitrogen (BUN) and creatinine (Cr) levels in patients with renal impairment undergoing open-heart surgeries.   Methods: This double-blind clinical trial was performed on 66 patients undergoing cardiac surgeries with preoperative Cr levels of greater than 1.5 mg/dL. The patients were randomly divided into 3 groups. The first group received propofol and remifentanil via the TCI system. The second group received these 3 drugs via the usual dosing (mg/kg) method. The third group received midazolam and fentanyl conventionally (based on the mg/kg method). Postoperative Cr and BUN levels, urine volume, the need for dialysis, and hemodynamic parameters were recorded up to 3 postoperative days. After the exclusion of 10 patients from the study, 56 patients were analyzed.   Results: Postoperative BUN and Cr values were significantly lower in the TCI group than in the other groups (P<0.05) There were no significant differences between the 3 groups concerning hemodynamic status. The total dose of anesthetics was significantly lower in the TCI group than in the propofol-remifentanil group (P<0.05). The incidence of postoperative arrhythmias in the TCI group was significantly lower than that in the other 2 groups (P<0.05).   Conclusions: In our patients with renal dysfunction, the TCI method reduced post-cardiac surgery BUN and Cr levels, the dose of the anesthetics administered, and the incidence of arrhythmias.
