objective to explore the reasonable utilization of cephalosporins in chronic renal failure patients with cephalosporin encephalopathy.method we retrospectively analyzed the clinical characteristics of 29 crf patients,who developed encephalopathic syndrome and was treated with cephalosporin.results the encepha1opathic syndrome include (1)mental confusion in 4 cases;(2)unconsciousness in 2 cases;(3)seizure in 23 cases.physical examination did not show signs of cerebral focal injury.computed tomography of the brain in 29 patients did not show acute lesions.the state of neurotoxicity was completely recovered after discontinuation of cephalosporins.conclusion cephalosporins used in conventional doses or reduced doses can cause temporary encephalopathy in patients with crfwhich might due to prolongation of drug half life.
