[Problems associated with general anesthesia in patients with thyroid cancer].

The group of 100 patients with thyroid cancer operated in Institute of Oncology in Gliwice was described. The risk of anaesthesia, intraoperative complications and the results obtained depend on the preoperative preparation, especially on adequate treatment of endocrine disorders of thyroid, parathyroid and adrenal glands. It is necessary to estimate the presence of multiendocrine disorders in medullary thyroid carcinoma, especially of those with pheochromocytoma, because of its high mortality in the non alfa-blockers prepared patients.
