[The E.E.G. during althesin anaesthesia in paediatrics (preliminary study) (author's transl)]. / Etude de l'E.E.G. au cours de l'anesthésie par l'alfatésine en pédiatrie.

The authors studied 11 children (mean age 5 1/2 years) before and during anaesthesia, and then several times from 1 to 6 hours after the injection of althesin. The anaesthetic agent was either pure althesin or althesin combined with dextromoramide. The electroclinical correlations described for adults are also found in children: slow waves, discontinuous and then isoelectric recording during the operation stage, then rapid recovery after ending drug administration. The special interest of this study was the analysis of E.E.G. recordings during the hours following clinical recovery: only once was the recording like that of full consciousness. Repeated recordings were all of drowsiness and even sleep, despite the clinical state of the subject. A short associated study concerns the E.E.G. of neonates during their first 24 hours, born to mothers anaesthetised with alfathesin.
