Abstract:
OBJECTIVETo clarify the frequency, presentation, associated factors, treatment and outcome of hyponatremia after transphenoidal surgery of pituitary adenomas.
METHODSRetrospectively reviewed the database of 183 patients who underwent transphenoidal surgery of pituitary adenoma between January 1999 and June 2000 in our department.
RESULTS38.8% (71/183) had postoperative hyponatremia. Among them, 59.2% (42/71) appeared on the 4th to 7th day postoperatively. 59.2% (42/71) presented with nausea, vomiting, headache, dizziness, confusion and weakness. Hyponatremia was related to age, tumor size and adenoma type, but not related to sex and degree of resection. Treatment consisted of salt replacement and mild fluid restriction in 4 patients and salt and fluid replacement in 67 patients. Hyponatremia resolved within 16 days in all the patients.
CONCLUSIONSHyponatremia often appeared about 7 days after transsphenoidal surgery of pituitary adenomas, especially in elderly and patients with macroadenomas and huge pituitary adenomas. The principle of treatment was salt and fluid replacement.
