[Dextrose and vigilance: the effect of dextrose on the spectro-analytic parameters of pharmaco-EEG].
In a randomized single-blind cross-over-design the effect of 15 g dextrose was investigated against placebo with 48 healthy subjects at two different days each. The quantitative pharmaco-EEG was recorded occipitocentral at the left side (O1-Cz) under vigilance controlled conditions and then under resting conditions (three minutes each). Having measured its baseline it was repeated six times every 20 minutes starting 10 minutes after the application of the substance. After the administration of dextrose a stabilization of vigilance could be seen in the EEG by the following differences of statistical significance (p < = 0.05) between dextrose and placebo under resting recording conditions: In the first control (14.-16. minute post) there was a significant decrease of the relative power in the delta and in the theta range combined with an increase of alpha 2. In the second control (34.-36. minute post) there was a significant decrease of relative power in the theta range and significant increase in the alpha 1 range. In the third control (54.-56. minute post) and later on no effects of dextrose were left in the pharmaco-EEG. The significant differences in the first and second control have to be interpreted as follows: After the administration of dextrose the level of vigilance was increased compared to the placebo group.
