[Dimer-X in the intracranial subarachnoid space - electrocorticographic study (author's transl)].

As a sequel to our first report, we are now presenting the results of the ECoG examination of the rats in about 15 min. after injecting Dimer-X into their cisternae magnae. The injection of 28% iodine Dimer-X into the cisterna magna causes the multiple bursts of spikes, but the occurrence is less frequent when the low concentration of Dimer-X are injected. The ECoGs show occurence of a few spikes with the premedication of Valium or Decadron, and very few spikes are seen on the ECoG, when Valium and Decadron are given as a premedication. From these results as seen on ECoG, we conclude that during Dimer-X ventriculography lw concentration of Dimer-X should be used with premedication of Valium and Decadron.
