[Treatment of status epilepticus in the adult. Retrospective analysis of 192 cases treated in intensive care units].
The results of therapy have been analyzed in a series of 192 patients admitted for status epilepticus over 7 years in two intensive care units. Most (142 cases without any prior epilepsy) corresponded to secondary forms. In 2/3 of the cases, the patients were admitted because of failure of benzodiazepines and/or phenobarbitone. ⋯ Chlormethiazole often succeeds in controlling convulsive status which has proved refractory to other treatment. Supportive management is mandatory: 52% of patients required respiratory assistance. Fatalities (36%) exclusively correspond to the underlying cerebral conditions and systemic disorders.

[Comparative study of the nociceptive reflex and late components of the evoked somatosensory potential during stimulation of the sural nerve in healthy subjects].
A study was carried out with 10 normal volunteers in order to find a correlation between nociceptive flexion reflexes from the biceps femoris muscle and the amplitude of the late component (N150-P220) of the vertex evoked potential elicited by sural nerve stimulations at various intensities randomly delivered. The range of stimulus varied from the perception threshold (usually 1 mA) to 2 times the reflex threshold. ⋯ No significant correlation was found between the recruitment curve of the nociceptive reflex and that of the late component of the evoked potential as a function of stimulus intensity. Functional implications of these data are discussed.

[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.

[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).
