Intracisternal dimer X: Toxicity and prophylaxis

Abstract
Although Dimer X is said to be a low toxic water soluble contrast medium, epileptic seizures sometimes occur during or after Dimer X ventriculography. The toxicity of this dye was examined in rats and possible prophylactic measures were evaluated. From the results of our experiment it was concluded that Dimer X of low concentration should be used with premedication of Valium and Decadron.
