Anesthesia for glucagonoma resection.

Anesthetic experience with three cases of the resection of glucagonoma, a rare tumor of alpha cells of pancreatic islets, is presented. Marked increases of blood glucagon and glucose levels, with the potential for clinically significant metabolic and myocardial dysfunction, did not occur during anesthesia and surgery. Associated tumors of other endocrine cell types also were absent in the three study patients. Strategies for anticipating and managing other perioperative problems associated with glucagonoma also are discussed.

Monitoring parenteral nutrition intraoperatively with the dextrometer.

Patients receiving parenteral nutrition support frequently undergo operative procedures. Proper selection of patients and close monitoring of glucose levels are crucial if parenteral nutrition is to be maintained intraoperatively. The Dextrometer was used in 10 patients receiving parenteral nutrition intraoperatively. The difference between the Dextrometer readings and the serum glucose level obtained by laboratory analysis was less than 10% in 83% of cases and readings were most accurate in the 200 to 400 mg/dl range. The Dextrometer provides a simple, inexpensive, and reasonably accurate method of monitoring glucose intraoperatively as part of the optimal management of these patients.
