Serum cholinesterase activity following enflurane anaesthesia

Serum cholinesterase activity was determined in 30 female patients anaesthetized with enflurane for excision of lump in the breast. In all 30 patients biopsy of the tumor was negative for carcinoma. Blood samples were taken before induction of anaesthesia, at the end of the operation and 24 hours after the operation. Enzymatic determinations were performed by the Boerhinger cholinesterase kit.

Enzyme levels were found sufficiently high at the end of the operation and returned to the preoperative levels 24 hours post-operatively.

Ľactivité de la cholinestérase sérique a été étudiée chez trente malades du sexe féminin subissant ľexérèse ďune masse au sein. Aucune des lésions ne s’est avérée maligne. Des échantillons de sang furent prélevés avant ľinduction de ľanesthésie, à la fin de ľopération et 24 heures plus tard. Les dosages enzymatiques ont été effectués par la technique Boerhinger.

Tout en demeurant dans les limites normales, ľactivité cholinestérasique a subis une baisse significative à la fin de ľopération. Le retour au niveau pré-opératoire s’est produit dans les 24 heures.
