Abstract:

Objective To investigate the etiology, regularity and treatment of postoperative hyponatremia of sella region tumor in children. Methods Clinical studies of 81 patients with postoperative hyponatremia of sella region tumor were reviewed retrospectively. Recording serum sodium on the operative day and postoperation daily, corresponding therapy according to the serum sodium and patient's condition was also recorded. Results Purely hyponatremia was observed in 81 of 450 cases. Mild moderate and severe cases hyponatremia were 28(34.6%), 35(43.2%) and 18(22.2%), respectively. 26 cases(32.1%)had disturbance of consciousness. 50.6%(41/81) was occurred on operative day and the first day after operation. 83.9%(68/81) was recovered within 8 d. Conclusion SIADH and CSWS are cardinal etiological factors of hyponatremia in children associated with sella tumor. Grasping the regularity and etiology can redress the sodium irregularity effectively and shorten the pathological process.
