["Spike focus" during the evolution of febrile convulsion: an electrophysiological and clinical study of 35 patients (author's transl)].
Out of 500 patients with febrile convulsions, 41 were found to have a spike focus on E. E. G., 35 of these were then followed up. ⋯ In 35 patients the focus disappeared, in 45 p. 100 within a year and in 88 p. 100 within 3 years. Following the disappearance of the focus, generalised sharp wave activity was seen in 30 p. 100 cases, all 35 children being under treatment. All the seizures with the exception of two children who have become epileptic were benign rendering long term anticonvulsant therapy unnecessary.

[The Vasalva manoeuvre and the E.E.G. in a study of professional and trainee diverse (author's transl)].
The E. E. G., the oculocardiac reflex (OCR), the Valsalva manoeuvre and respiratory capacity, were studied and compared in 183 professional or trainee divers. ⋯ The Valsalva was more often positive in young subjects and trainee divers than in older subjects and professional divers. Also the Valsalva response was more likely to be positive when the subject's respiratory capacity was greater. These observations are used to make conclusions about the significance of a positive response to the Valsalva manoeuvre and about the value that can be attached to these various tests in subject selection.

[Monitoring the integrity of saccadic eye movements as a test of post-anaesthetic recovery (author's transl)].
After reviewing various tests of consciousness which can be used during the post-anaesthetic period, the authors chose to analyse the involvement of the visual receptor during different stages between sleep and complete recovery of consciousness, by an electro-oculographic (EOG) method, providing recordings of the displacement of the optical axis. In states of full consciousness the eye explores a static flat surface in saccades separated by pauses. ⋯ In a second group, the state of consciousness was monitored 2 hours after the last injection of the anaesthetic drug, so that correlations could be considered with the type of anaesthesia used. Th conclusion concerns the practical interest of the method (short term hospitalisation after general anaesthetic, medico-legal use due to the existence of a recording) and its basic use in the experimental study of new drugs in man.

[An examination of current techniques in anaesthesia (author's transl)].
The techniques of general anaesthesia may be divided into 2 major groups: those used in very brief surgical or diagnostic operations and those used in longer and more pain-producing interventions. The former normally involve a single drug which is very short-acting and allows consciousness to be recovered rapidly and well. The latter are anaesthetics using several drugs together, which allows very precise control of the degree of analgesia, neuro-vegetative protection, muscle relaxation and sleep. ⋯ E. G. remains a technique of choice for studying recovery, and any sequels of hypoxia during the operation. This should, of course, be accompanied by a clinical evaluation which is particularly important in assessing the state of ventilation (residual curarisation, depression by central analgesics).
