Summary
This study shows that there are two distinct types of muscular hyperactivity which occur during recovery from all types of inhalation anaesthesia. Spasticity, which occurred in the large majority of patients, seemed to be part of the normal recovery pattern. Shivering, on the other hand, occurred in fewer than half the patients and seemed to be largely related to temperature loss during the operative procedure.
Muscular hyperactivity during recovery from general anaesthesia has been reported by various authors, and has been particularly related to halothane anaesthesia. In order to determine the nature of this phenomenon more than 215 patients were closely observed during emergence from general anaesthesia with various inhalation agents.
It appears that there are two distinct types of muscular hyperactivity. The first, spasticity, occurred in the large majority of patients and seemed to be part of the normal recovery pattern. The second was shivering, which occurred in fewer than half the patients and seemed to be largely related to interoperative heat loss. Both forms of hyperactivity occurred with all agents studied,
Résumé
Différents auteurs ont fait part de ľobservation ďune hyperactivité musculaire chez les malades au réveil après une anesthésie générale et, cette hyperactivité musculaire était reliée particulièrement à ľusage du fluothane. Dans le but de préciser la nature de ce phénomène, nous avons observé de près 215 malades au cours du réveil après une anesthésie générale avec différents agents par inhalation.
Il semble qu’il existe deux sortes ďhyperactivité musculaire. La première est un état de spasmodicîté qui apparait chez la plupart des malades et semble faire partie des observations du réveil normal. La deuxième est: le frisson; il apparaît chez moins de la moitié des malades et il est vraisemblablement relié à la perte de chaleur préopératoire. Nous avons observé ľexistence de ces deux sortes ďhyperactivité muculaire avec tous les agents que nous avons étudiés.
