Perioperative fluid and electrolyte management in children undergoing surgery for craniopharyngioma - A 10-year experience in a single institution

In a retrospective study, the intra- and early postoperative data of 39 children with 46 operations for craniopharyngioma were analyzed. Diabetes insipidus (DI) occurred in 30 out of 32 cases without preoperative evidence of DI. We observed that all children who did not have a pituitary stalk preserved and 5 out of 7 patients with preserved pituitary stalk developed DI within 18 h of surgery. Short-term inappropriate secretion of antidiuretic hormone (SIADH) occurred in 2 children, but was quickly followed by DI. The time of onset of DI and SIADH did not correlate with sex, age, body weight, location of tumor, or duration or extent: of surgery. Parenteral desmopressin was an effective treatment for intra- and postoperative DI. The duration of the clinical effect of desmopressin administration varied in different patients between 4 and 23 h. An approach to the immediate intra- and postoperative management of children with craniopharyngioma is presented.
