| Research Abstract |
We investigated the effects of circulating asymmetric dimethylarginine (ADMA) which is an endogenous competitive inhibitor of nitric oxide synthase (NOS) on CO_2R in 36 patients with chronic renal failure(CRF) or in 100 patients who underwent off-pump coronary artery bypass graft surgery.CO_2R was impaired concentration-dependently by BUN but ADMA did not contribute to the impairment of CO_2R in the patients with CRF during general anesthesia. In the patients with off-pump CABG surgery, 12% patients developed postoperative cognitive dysfunction, associating not with ADMA concentration but with impairment of CO_2R during anesthesia.
