[Study of recovery from anesthesia by means of graphic tests of writing and drawing]

As part of an investigation of the quality of the return to consciousness after anaesthesia, a comparison was made between recovery times in 60 patients divided into three groups, subjected to general anaesthesia and shallow maintenance with halothane, mixed short shallow neuro-analgesia, and short analgesia anaesthesia. Psycho-aptitudinal recovery was evaluated with three graphic tests. The results indicate that recovery times are much shorter for shallow neuro-analgesia, and particularly for analgesic anaesthesia by comparison with ordinary shallow techniques coupled with maintenance in O2 + N2O + Halothane.
