title: [Anesthesia for surgery of insulinoma].
abstract: The difficulties of interpretation of blood sugar level changes during the postoperative period in the anaesthetic management of insulinoma are discussed. Several specific means reduced the errors in the assessment of the hyperglycemic rebound which occurred after the removal of the tumour. They consisted of continuous sugar infusion accorded to measured glucose levels, in order to maintain a constant blood sugar value between 50 and 70 mg X 100 ml-1 before removal of the insulinoma. Furthermore, analgesia was provided by high doses fentanyl. Sugar containing solutes were avoided during the procedure. Glucose levels rose slowly after tumour removal and reached 170 mg X 100 ml-1 at 120 min. This rebound was known to be of no help in ascertaining complete resection. Simultaneous determinations of blood glucose and insulin were obtained. The value of portal blood insulin was found to be normal (12.3 mU X l-1) 30 min after insulinoma removal. Turner's index calculated every 30 min decreased simultaneously (143) and reached a normal value at 120 min (39). These results, obtained during the surgical procedure all the more easily because of rapid laboratory procedures, could be better arguments in determining whether tumour removal has been complete.
