abstract：:I653 is a new volatile anesthetic structurally similar to enflurane and isoflurane. Since enflurane can induce convulsions, whereas isoflurane progressively depresses cortical electrical activity, the authors believed it important to assess the effect of I653 on the EEG (in both the "time" and "frequency" domain). The...
