Thiopental anaesthesia and the acid-base balance in the blood of experimental dogs.

An analysis of basic parameters representative of the acid-base balance was made in arterial blood samples from 140 clinically healthy dogs, under a general intravenous Thiopental anaesthesia. The following mean values +/- S.E.M. were obtained: pH = 7.33 +/- 0.01; pCO2 = 47.16 +/- 0.95; base excess = -2.12 +/- 0.27; buffer base = 46.63 +/- 0.37. The results showed a prevalent trend of lower values of pH, base excess and buffer base and higher values of pCO2 than those found commonly in human clinical practice. Special attention was paid to the respiratory component of the acid-base balance (ABB) revealing certain undesirable side effect of Thiopental anaesthesia.

A technique for on-line classification of evoked potentials into two groups according to subjective interpretation of the stimulus.

A technique is described for on-line classification of evoked potentials (EPs) into distinct groups for separate averaging according to a criterion available after the beginning of the EPs. It is suitable for analysing psychophysiological correlations (relationship between EPs and subjective perception). The system consists of a slightly modified NTA 512 B (Hungarian) average response computer (however, any CAT-computer-like device can be used in a similar way) and of an additional device. It can be used in all cases when the number of subjective judgements according to which EPs have to be classified can be limited to two (or three, when, by slightly changing the system, all quarters of memory are used).
